Atmospheric concentrations of carbon dioxide surpassed a notable milestone this week.


Special note on May 9, 2013 reading



May 10, 2013 Comment:
NOAA has reported 400.03 for May 9, 2013, while Scripps has reported 399.73. The difference partly reflects different reporting periods. NOAA uses UTC, whereas Scripps uses local time in Hawaii to define the 24-hr reporting period. If Scripps were to use same reporting period as NOAA, we would report 400.08 for May 9.

Press Release:


Climate change will cause widespread global-scale loss of common plants and animals


EMBARGO: 18.00 BST (London Time) on SUNDAY MAY 12, 2013 (13.00 US EST on SUNDAY MAY 12, 2013)


Quantifying the benefit of early climate change mitigation in avoiding biodiversity loss‘ will be published by the journal Nature Climate Change
on Sunday May 12, 2013.


Almost two thirds of common plants and half the animals could see a dramatic decline this century due to climate change – according to research from the University of East Anglia.  Research published today in the journal Nature Climate Change looked at 50,000 globally widespread and common species and found that two thirds of the plants and half of the animals will lose more than half of their climatic range by 2080 if nothing is done to reduce the amount of global warming and slow it down. This means that geographic ranges of common plants and animals will shrink globally and biodiversity will decline almost everywhere.

Plants, reptiles and particularly amphibians are expected to be at highest risk. Sub-Saharan Africa, Central America, Amazonia and Australia would lose the most species of plants and animals. And a major loss of plant species is projected for North Africa, Central Asia and South-eastern Europe. But acting quickly to mitigate climate change could reduce losses by 60 per cent and buy an additional 40 years for species to adapt. This is because this mitigation would slow and then stop global temperatures from rising by more than two degrees Celsius relative to pre-industrial times (1765). Without this mitigation, global temperatures could rise by 4 degrees Celsius by 2100.

The study was led by Dr Rachel Warren from UEA’s school of Environmental Sciences and the Tyndall Centre for Climate Change Research. Collaborators include Dr.Jeremy VanDerWal at James Cook University in Australia and Dr Jeff Price, also at UEA’s school of Environmental Sciences and the Tyndall Centre. The research was funded by the Natural Environment Research Council (NERC). Dr Warren said: “While there has been much research on the effect of climate change on rare and endangered species, little has been known about how an increase in global temperature will affect more common species. “This broader issue of potential range loss in widespread species is a serious concern as even small declines in these species can significantly disrupt ecosystems.

“Our research predicts that climate change will greatly reduce the diversity of even very common species found in most parts of the world. This loss of global-scale biodiversity would significantly impoverish the biosphere and the ecosystem services it provides.

“We looked at the effect of rising global temperatures, but other symptoms of climate change such as extreme weather events, pests, and diseases mean that our estimates are probably conservative. Animals in particular may decline more as our predictions will be compounded by a loss of food from plants.

“There will also be a knock-on effect for humans because these species are important for things like water and air purification, flood control, nutrient cycling, and eco-tourism. “The good news is that our research provides crucial new evidence of how swift action to reduce CO2 and other greenhouse gases can prevent the biodiversity loss by reducing the amount of global warming to 2 degrees Celsius rather than 4 degrees. This would also buy time – up to four decades – for plants and animals to adapt to the remaining 2 degrees of climate change.”

The research team quantified the benefits of acting now to mitigate climate change and found that up to 60 per cent of the projected climatic range loss for biodiversity can be avoided. Dr Warren said: “Prompt and stringent action to reduce greenhouse gas emissions globally would reduce these biodiversity losses by 60 per cent if global emissions peak in 2016, or by 40 per cent if emissions peak in 2030, showing that early action is very beneficial. This will both reduce the amount of climate change and also slow climate change down, making it easier for species and humans to adapt.” Information on the current distributions of the species used in this research came from the datasets shared online by hundreds of volunteers, scientists and natural history collections through the Global Biodiversity Information Facility (GBIF).

Co-author Dr Jeff Price, also from UEA’s school of Environmental Studies, said: “Without free and open access to massive amounts of data such as those made available online through GBIF, no individual researcher is able to contact every country, every museum, every scientist holding the data and pull it all together. So this research would not be possible without GBIF and its global community of researchers and volunteers who make their data freely available.”

Targeted action needed to protect waterbirds

Wetlands are disappearing rapidly worldwide in spite of performing vital functions including flood defence, removal of nutrients and toxicants, and providing humans with essential services such as drinking water, fish stocks and water for agriculture. Credit: Tamas Szekely

May 01, 2013 ( —Researchers from our Biodiversity Lab have identified specific areas around the world where conservation efforts could best be targeted to safeguard inland-breeding waterbirds. In their new report, the first ever global study of its kind, Laura Williamson and Professor Tamás Székely, analysed data from 471 species of birds, focusing on waterbird species which breed in inland wetlands. These inland wetland habitats are important breeding grounds for birds and are strongly affected by human activities. Waterbirds make up around 10 per cent of all bird species and are an important indicator for the health of a wetland ecosystem, including lakes, streams and rivers. The main threats to waterbirds are from habitat loss, primarily caused by human activities such as land reclamation and development, agriculture, pollution, transportation and energy production…..



Fracking Water Use Draining Resources, Especially In Western U.S., New Studies Find

Posted: 05/09/2013 11:50 am EDT

The natural gas extraction technique known as fracking uses so much water that it could threaten groundwater resources, especially in the Western U.S., two new reports conclude. The first report (pdf), from the Western Organization of Resource Councils (WORC), found that hydraulic fracking removes 7 billion gallons of water every year in just four states: North Dakota, Wyoming, Montana and Colorado. The organization blames inadequate federal and state-level protections for the use and/or contamination of fresh water. “Fracking’s growing demand for water can threaten availability of water for agriculture and Western rural communities,” WORC board member Bob LeResche said in a prepared release. He also told The Dickinson Press that “Unless our states take real action soon, we stand to watch our agricultural economies, and even our human habitation of some places, disappear. Ninety-nine percent of rural Americans rely on groundwater for their domestic needs, as do 51 percent of all Americans.” WORC is calling on states to improve the way they monitor and regulate oil and gas drilling, especially where it affects water — and in many states, water issues are handled by multiple agencies, none of which take full responsibility for water usage. The second report, from the sustainable business organization Ceres, said fracking is affecting water-stressed regions throughout the country, with Texas and Colorado being two of the most heavily affected states. The Ceres report used data on more than 25,000 wells collected by and compared it with water stress indicator maps. Their research concluded that 47 percent of wells are being developed in areas where the water basins are currently suffering from either high or extremely high water stress. “These findings highlight emerging tensions in many U.S. regions between growing hydraulic fracturing activity and localized water supply needs,” Ceres President Mindy Lubber said in a prepared statement…..

Orcas feast on gray whale calves off Monterey

David Cruz, Natures Lantern–Killer whales hunt gray whale calves as they migrate across a canyon in Monterey Bay.

By Peter Fimrite SF Chronicle May 6, 2013

Scores of killer whales are patrolling Monterey Bay, ambushing gray whales and picking off their young as the leviathans attempt to cross a deepwater canyon that bisects their annual migration route. It is a desperate situation for the migrating mother whales, which are trying to lead their calves through a gauntlet of hungry orcas to reach their feeding grounds in Alaska. Whale watchers and scientists, who are crowding onto boats to witness the action, have described it as the “Serengeti of the Sea.” …Scientists say the violent drama, involving fleeing whales and pursuing packs of orcas, is an annual extravaganza of death off the coast of Monterey that is growing in intensity as the number of whales and orcas increase.The mother gray whales and their calves leave their breeding grounds in Baja, Mexico, in April and travel north along the Northern California coast this time each year. As many as 35 whales and calves a day are swimming by right now, hugging the shore trying to elude predators, Black said. The problem for the mothers and calves is that they must navigate around a deepwater depression, called the Monterey Submarine Canyon, at Point Pinos…..Transient killer whales, which at 22 to 26 feet long are the ocean’s apex predators, congregate along the edges of the canyon, which starts a quarter mile from shore and is 6,000 feet deep in the middle. They wait for the big beasts – which are about 45 feet long – to attempt the crossing, kind of like crocodiles waiting for migrating wildebeests to swim across the Nile.

The more stealthy grays take the long way around, sticking close to shore and swimming through the kelp beds, but some of the more bold or hurried whales cut across the canyon, using sonar to follow the contour lines at the bottom.

“It is one of the few places on the gray whale migration where they have to leave the protection of the shore,” said Black, who has been studying killer whales since 1992 and is considered the Bay Area’s foremost expert. “The killer whales come in the area and patrol the canyon, searching for calves.” Most of the attacks occur along the edge of the drop-off, where packs of between four and seven mostly female orcas use the cover of deep water to approach from underneath, said Black and other researchers. It is not an easy kill. The calves are 18 to 20 feet long, weighing many tons. ….



Progress made removing Nevada mine-claim pipes that can kill birds

May 4, 2013 Reno

Wildlife officials and conservationists in Nevada said they’re making progress knocking down the white plastic pipes that miners traditionally have used to stake their claims, because such markers can become death traps for hundreds of thousands of small birds that get stuck inside. The U.S. Bureau of Land Management estimated there are more than 3.4 million of the white polyvinyl chloride pipes sticking out of the ground across the West — more than 1 million in Nevada alone in a 2011 survey. The American Bird Conservancy, Nevada Department of Wildlife, BLM and several mining companies have been tracking and removing the pipes, which have been required since 2009 to be replaced by solid posts under state law in Nevada, the biggest producer of gold in the nation and sixth-largest in the world. Darin Schroeder of the American Bird Conservancy estimates the PVC markers cause the death of more than a million birds a year nationally. He said small cavity-nesting birds mistake the openings for an ideal home, but once inside are doomed by the smooth sides of the pipe with a narrow diameter that keeps them from climbing or flying out…

Rising sea levels threaten migratory birds –

Phys.Org May 6 2013

Migrant egrits fly around a rice field looking for food in Pampanga province, the Philippines on January 23, 2011.

Millions of birds that stop at coastal wetlands during annual migrations could die as rising sea levels and land reclamation wipe out their feeding grounds, researchers warned Monday. The study into the migratory habits of shorebirds predicted that a loss of 23 to 40 percent of their main feeding areas could lead to a 70 percent decline in their population. Led by a team of scientists from Australia’s government-backed National Environmental Research Programme, the study said some areas have already reported alarming population losses of 30-80 percent. “Each year, millions of shorebirds stop at coastal wetlands to rest and feed as they migrate from Russia and Alaska to the coasts of Southeast Asia and Australasia,” said researcher Richard Fuller. “We’ve discovered that some of these wetlands are highly vulnerable to sea level rise and might be lost in the next few decades. “If the birds can no longer stop at these areas to ‘refuel’, they may not be able to complete the journey to their breeding grounds.” The researchers studied wetlands along migration routes across Alaska, Russia, China, North Korea, South Korea, Japan, Philippines, Vietnam, Thailand, Malaysia, Indonesia, Papua New Guinea, Australia and New Zealand.

In many cases rapid coastal development and reclamation for agriculture were already chewing into tidal wetlands the birds use as feeding grounds on their long journeys, which sometimes extend half way around the world. Species showing signs of being in trouble include the bar-tailed godwit, curlew sandpiper, great knot, grey-tailed tattler, lesser sand plover, and red knot, said the study, published in the Proceedings of the Royal Society B journal. The scientists used “graph theory“, a mathematical approach, to estimate the impact of the loss of these wetlands on shorebirds. It found that if a tidal wetland habitat served as an important “stepping stone” for the shorebirds, a small amount of habitat loss could trigger disproportionately large declines in bird populations. “This is because some of these tidal wetlands are ‘bottleneck’ sites where the majority of the birds stop to refuel,” said Takuya Iwamura, of Stanford University. “For example, we discovered that a sea level rise of 150 centimetres (59 inches) may result in the loss of 35 percent of coastal wetlands, but it could lead to a 60 percent decline in curlew sandpipers, eastern curlews and great knots.”

On Top Of Sea Ice Death Spiral, Ocean Acidification Poised To Radically Alter Arctic

Posted: 08 May 2013 07:59 AM PDT

The Arctic is the fastest changing place on earth. The most obvious and important change is the staggering loss of sea ice (see “CryoSat-2 Confirms Sea Ice Volume Has Collapsed“). In addition, “the Arctic marine waters are experiencing widespread and rapid ocean acidification,” a new study finds. This first-ever Arctic Ocean Acidification Assessment, commissioned by the Arctic Council’s Arctic Monitoring and Assessment Programme (AMAP), explains that the “primary driver of ocean acidification is uptake of carbon dioxide emitted to the atmosphere by human activities.” We knew from a 2010 Nature Geoscience study that the oceans are now acidifying 10 times faster today than 55 million years ago when a mass extinction of marine species occurred. We are risking a marine biological meltdown “by end of century” as a 2010 Geological Society study put it. As the lead author of a 2012 study on acidification in Science explained, “if industrial carbon emissions continue at the current pace, we may lose organisms we care about—coral reefs, oysters, salmon.”

Here is a video from AMAP on Arctic Ocean acidification:

Most species of gigantic animals that once roamed Australia had disappeared by the time people arrived, a major review of the available evidence has concluded. The research challenges the claim that humans were primarily responsible for the demise of the megafauna in a proposed “extinction window” between 40,000 and 50,000 years ago, and points the finger instead at climate change.



Global Warming: We are halfway to a mass extinction event

5/10/2013 10:00am by Gaius Publius

As you may know, we’ve restarted our climate crisis writing here at La Maison, beginning with this piece, a global warming picture “from 10,000 feet”:

The climate crisis in three easy charts

There we took the long view and noticed that the big temperature spike in the early days of the Cambrian, some 540 million years ago when life on earth was exploding in number and diversity of species, is a match for the temperature spike we could very well see in 2100 under the “do nothing” carbon scenario. The Cambrian temperature spikes reached 7°C (12.5°F) above pre-industrial (pre-1800) norms, which is also where we could be headed if we don’t stop.

We also saw that the entire period of time from the Cambrian (again, about 540 million years ago) until now is divided into just three geologic eras, or major divisions …

… and that each of the first two eras ended in a major mass extinction event. Will a mass extinction end the Cenozoic Era, the Age of Mammals? If we hit a warm enough temperature, yes. This piece explains why and looks at the broad consequences for man under a couple of warming scenarios.

What does “major mass extinction” mean?

In order to discuss global warming and mass extinction, we need to look at mass extinctions in general to get a sense of the scale of these events and their effect.

Consider again the chart of extinctions since the Cambrian, 540 million years ago. (This chart was presented in slightly different form here.) The labels across the top — “Cm” and so on — are geologic “periods”. For your convenience I’ve added the larger divisions, the three geologic eras as well, and indicated where the current geologic period, the Quarternary, fits in…..


As climate changes, boreal forests to shift north, relinquish more carbon than expected…

Phys.Org  – ‎ May 5, 2013‎

It’s difficult to imagine how a degree or two of warming will affect a location. Will it rain less? What will happen to the area’s vegetation? New Berkeley Lab research offers a way to envision a warmer future. It maps how Earth’s myriad climates—and the ecosystems that depend on them—will move from one area to another as global temperatures rise. The approach foresees big changes for one of the planet’s great carbon sponges. Boreal forests will likely shift north at a steady clip this century. Along the way, the vegetation will relinquish more trapped carbon than most current climate models predict. The research is published online May 5 in the journal Nature Geoscience. Boreal ecosystems encircle the planet’s high latitudes, covering swaths of Canada, Europe, and Russia in coniferous trees and wetlands. This vegetation stores vast amounts of carbon, keeping it out of the atmosphere where it can contribute to climate change.

Scientists use incredibly complex computer simulations called Earth system models to predict the interactions between climate change and ecosystems such as boreal forests. These models show that boreal habitat will expand poleward in the coming decades as regions to their north become warmer and wetter. This means that boreal ecosystems are expected to store even more carbon than they do today. But the Berkeley Lab research tells a different story. The planet’s boreal forests won’t expand poleward. Instead, they’ll shift poleward. The difference lies in the prediction that as boreal ecosystems follow the warming climate northward, their southern boundaries will be overtaken by even warmer and drier climates better suited for grassland. And that’s a key difference. Grassland stores a lot of carbon in its soil, but it accumulates at a much slower rate than is lost from diminishing forests. “I found that the boreal ecosystems ringing the globe will be pushed north and replaced in their current location by what’s currently to their south. In some places, that will be forest, but in other places it will be grassland,” says Charles Koven, a scientist in Berkeley Lab’s Earth Sciences Division who conducted the research. “Most Earth system models don’t predict this, which means they overestimate the amount of carbon that high-latitude vegetation will store in the future,” he adds.

‘Mother Nature Turned Off The Spigot’: California Wildfires Fueled By ‘Remarkable’ Dry Weather Conditions

California has experienced record low rainfall since the “rain year” began in July 2012

Posted: 03 May 2013 09:35 AM PDT

A Southern California wildfire that burned through 8,000 acres yesterday has marked an early and ominous start to the state’s fire season. The fire, fueled by unusually dry conditions and 25 to 60 mph winds that usually aren’t seen until late fall, has damaged 15 homes and forced the evacuation of hundreds of Ventura County residents. As of today, the so-called Springs fire spans more than 15 square miles, with weather forecasts predicting temperatures in the 90s and continuing strong winds. California has experienced record low rainfall since the “rain year” began in July 2012, with Los Angeles receiving only about five inches of rain since then. Though the winter and early spring months are typically some of Califorina’s wettest, since 2013 began, downtown L.A. has received less than two inches of rain — a fraction of the 11 inches that’s typical for the region at this time of year. The year’s low rainfall coupled with strong Santa Ana winds have created perfect conditions for wildfires in the region, as climatologist William Patzert told the L.A. Times: It was promising up to December and then all of sudden Mother Nature turned off the spigot,” he said. “It’s remarkable to get Santa Anas in May.… Every way you look at it, it’s been remarkable, unusual and incendiary.” So far, firefighters in California have responded to more than 680 wildfires this year — 200 more the average for this point in the season. In addition to the Springs fire, a wildfire in Riverside County east of L.A. burned through at least 2,950 acres and destroyed two homes before being contained on Thursday, and several fires erupted in Northern California this week as well. The fire risk isn’t expected to let up as the summer goes on — forecasters doubt the Southern California region will receive substantial rain this summer, which has led federal officials to warn of a potentially “devastating” fire season for the state. And California’s isn’t alone. Multiple studies have linked the risk of stronger, more frequent wildfires to the effects of climate change — most recently, a federal report warned that climate change will double the area of the U.S. burned by wildfires by 2050. Thanks to dry, hot conditions in much of the western U.S., the National Interagency Fire Center predicted this week that fire season could begin early in Oregon and Washington this year as well as in California. In addition to California’s low rainfall, the state is experiencing decreased snowpack this year, a problem that, as well as exacerbating the state’s dry conditions, spells trouble for California’s freshwater supply. California’s snowpack levels are only at 17 percent of normal readings for this time of year. Water from snowpack usually accounts for up to 75 percent of western California’s freshwater supply and 30 percent of freshwater to the state as a whole…..


Climate change may bring drought to temperate areas, study says

Los Angeles Times May 5, 2013

WASHINGTON – Climate change may increase the risk of extreme rainfall in the tropics and drought in the world’s temperate zones, according to a new study led by NASA….”These results in many ways are the worst of all possible worlds,” said Peter Gleick, a climatologist and water expert who is president of the Pacific Institute, an Oakland research organization. “Wet areas will get wetter and dry areas will get drier.” The regions that could get the heaviest rainfall are along the equator, mainly over the Pacific Ocean and the Asian tropics. Increased aridity and drought could have a greater effect on human life, however, because those conditions are more likely to occur where most of the world’s population lives. In the Northern Hemisphere, drought-prone areas include the Southwestern United States, Mexico, North Africa, the Middle East, Pakistan and northwestern China. In the Southern Hemisphere, drought could become more likely in South Africa, northwestern Australia, coastal Central America and northeastern Brazil. “Large changes in moderate rainfall, as well as prolonged no-rain events, can have the most impact on society because they occur in regions where most people live,” said William Lau, the study’s lead author and a scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. “The regions of heavier rainfall, except for the Asian monsoon, may have the smallest societal impact because they usually occur over the ocean,” he added. The study is based on the results of 14 models that show agreement on the possible rainfall trends, Gleick said. The study will be published in the journal Geophysical Research Letters. ….To prevent the 2 degree Celsius rise and its effects, including extremes in rainfall, the world has to keep emissions of heat-trapping carbon dioxide below a ratio of 400 parts per million. According to the Scripps Institution of Oceanography at UC San Diego, there have been isolated measurements of 400 parts per million in the Arctic, and scientists expect readings in Hawaii to exceed 400 parts per million this month.



Decline in snow cover spells trouble for many plants, animals

For plants and animals forced to tough out harsh winter weather, the coverlet of snow that blankets the north country is a refuge, a stable beneath-the-snow habitat that gives essential respite from biting winds and subzero temperatures.

May 7, 2013 — For plants and animals forced to tough out harsh winter weather, the coverlet of snow that blankets the north country is a refuge, a stable beneath-the-snow habitat that gives essential respite from biting winds and subzero temperatures. But in a warming world, winter and spring snow cover in the Northern Hemisphere is in decline, putting at risk many plants and animals that depend on the space beneath the snow to survive the blustery chill of winter. In a report published May 2 in the journal Frontiers in Ecology and the Environment, a team of scientists from the University of Wisconsin-Madison describes the gradual decay of the Northern Hemisphere’s “subnivium,” the term scientists use to describe the seasonal microenvironment beneath the snow, a habitat where life from microbes to bears take full advantage of warmer temperatures, near constant humidity and the absence of wind. “Underneath that homogenous blanket of snow is an incredibly stable refuge where the vast majority of organisms persist through the winter,” explains Jonathan Pauli, a UW-Madison professor of forest and wildlife ecology and a co-author of the new report. “The snow holds in heat radiating from the ground, plants photosynthesize, and it’s a haven for insects, reptiles, amphibians and many other organisms.”….

Into The Valley Of Death Rode The 600, Into The Valley Of 400 PPM Road The 7 Billion

Posted: 05 May 2013 09:34 AM PDT Joe Romm

“Forward, the Light Brigade!”
Was there a man dismay’d ?
Not tho’ the soldier knew
Some one had blunder’d:
Theirs not to make reply,
Theirs not to reason why,
Theirs but to do & die,
Into the valley of Death
Rode the six hundred.

– “The Charge Of The Light Brigade,” Alfred, Lord Tennyson, 1854

How will poets memorialize us? How will we be remembered if, like the British light cavalry charging a well-prepared Russian artillery battery in the Crimean War in 1854, we don’t reason why, we just keep on our current path even though it is eself-evidently suicidal.

CO2 levels for past 12,000 years and projected to 2100 assuming no change in policies (via Koomey)

“It may seem impossible to imagine that a technologically advanced society could choose, in essence, to destroy itself, but that is what we are now in the process of doing.” So ends Field Notes from a Catastrophe, the terrific 2006 book by Elizabeth Kolbert, one of the country’s most thoughtful climate journalists. Certainly as we hit 400 parts per million (ppm) for the first time in human existence, with not even a plan to avoid 600 ppm, 800 ppm, and then 1000 — not even a national discussion or an outcry by the so-called intelligentsia – it is worth asking, why? Is there something inherent in homo “sapiens” that makes us oblivious to the obvious? In his latest analysis, uber-hedge fund manager Jeremy Grantham points us in the direction of a new book, Immoderate Greatness: Why Civilizations Fail, by William Ophuls. Grantham, a self-described “die hard contrarian,” is one of the few leading financial figures who gets both global warming and growing food insecurity (see “Welcome to Dystopia”: We Are “Entering A Long-Term And Politically Dangerous Food Crisis“). Ophuls’ treatise, a synthesis of various analyses for civilizations fail, is well worth reading, though it isn’t a sunny book. Grantham’s analysis is a short, marginally-more optimistic version of the book, augmented with his own thinking. Grantham begins…

Filling In The Gap On Climate Education In Classrooms

NPR May 07, 2013 4:35 PM

The auditorium at James Blake High School in Silver Spring, Md., is packed when Cy Maramangalam strolls onstage, sporting jeans and a shaved head. “All right, how’s everyone doing today?” he says to rousing cheers. It feels as if he’s about to introduce a hot new band, but Maramangalam is with the , or ACE, and he’s here to talk climate change. In the past few years, the nonprofit has put on multimedia presentations for more than 1 million students across the country. Think of it as Al Gore for Gen Y. “Check this out,” Maramangalam tells the students, as cartoon characters and graphs dance on a giant screen behind him. He explains that carbon dioxide levels are higher than they’ve ever been in 800,000 years, and that this is driving up the globe’s thermostat.

“Jacking up the temperature toward this point should be freaking people out,” he says. “But it’s happening quietly.” ACE aims to fill a big gap. Polls show most U.S. students learn little about climate change at school, and even many adults have a fuzzy notion of what causes it.

For the first time, new issued in April include climate change. But the standards, written by a consortium of science and education groups in consultation with 26 states, are only voluntary and could take years to roll out. So Maramangalam hopes to bring kids up to speed fast on a topic that scientists say must be urgently addressed…..





Global carbon dioxide levels set to pass 400ppm milestone

The concentration of carbon in the atmosphere over the next few days is expected to hit record levels

John Vidal The Guardian, Monday 29 April 2013 15.32 EDT

The concentration of carbon dioxide in the atmosphere has reached 399.72 parts per million (ppm) and is likely to pass the symbolically important 400ppm level for the first time in the next few days. Readings at the US government’s Earth Systems Research laboratory in Hawaii, are not expected to reach their 2013 peak until mid May, but were recorded at a daily average of 399.72ppm on 25 April. The weekly average stood at 398.5 on Monday. Hourly readings above 400ppm have been recorded six times in the last week, and on occasion, at observatories in the high Arctic. But the Mauna Loa station, sited at 3,400m and far away from major pollution sources in the Pacific Ocean, has been monitoring levels for more than 50 years and is considered the gold standard. “I wish it weren’t true but it looks like the world is going to blow through the 400ppm level without losing a beat. At this pace we’ll hit 450ppm within a few decades,” said Ralph Keeling, a geologist with the Scripps Institution of Oceanography which operates the Hawaiian observatory. “Each year, the concentration of CO2 at Mauna Loa rises and falls in a sawtooth fashion, with the next year higher than the year before. The peak of the sawtooth typically comes in May. If CO2 levels don’t top 400ppm in May 2013, they almost certainly will next year,” Keeling said. CO2 atmospheric levels have been steadily rising for 200 years, registering around 280ppm at the start of the industrial revolution and 316ppm in 1958 when the Mauna Loa observatory started measurements. The increase in the global burning of fossil fuels is the primary cause of the increase. The approaching record level comes as countries resumed deadlocked UN climate talks in Bonn. No global agreement to reduce emissions is expected to be reached until 2015. “The 400ppm threshold is a sobering milestone, and should serve as a wake up call for all of us to support clean energy technology and reduce emissions of greenhouse gases, before it’s too late for our children and grandchildren,” said Tim Lueker, an oceanographer and carbon cycle researcher with Scripps CO2 Group. The last time CO2 levels were so high was probably in the Pliocene epoch, between 3.2m and 5m years ago, when Earth’s climate was much warmer than today…..


The measure of global warming

Carbon-dioxide concentrations hit their highest level in 4m years

May 11th 2013

AT NOON on May 4th the carbon-dioxide concentration in the atmosphere around the Mauna Loa Observatory in Hawaii hit 400 parts per million (ppm). The average for the day was 399.73 and researchers at the observatory expect this figure, too, to exceed 400 in the next few days. The last time such values prevailed on Earth was in the Pliocene epoch, 4m years ago, when jungles covered northern Canada. There have already been a few readings above 400ppm elsewhere—those taken over the Arctic Ocean in May 2012, for example—but they were exceptional. Mauna Loa is the benchmark for CO2 measurement (and has been since 1958, see chart) because Hawaii is so far from large concentrations of humanity. The Arctic, by contrast, gets a lot of polluted air from Europe and North America. The concentration of CO2 peaks in May, falls until October as plant growth in the northern hemisphere’s summer absorbs the gas, and then goes up again during winter and spring. This year the average reading for the whole month will probably also reach 400ppm, according to Pieter Tans, who is in charge of monitoring at Mauna Loa, and the seasonally adjusted annual figure will reach 400ppm in the spring of 2014 or 2015…







Republican Senators Boycott Vote On Gina McCarthy’s Nomination To Head EPA

Posted: 09 May 2013 08:53 AM PDT

Zero Republicans show up to vote on Gina McCarthy’s nomination to be EPA Administrator.

The Senate Environment and Public Works Committee was scheduled to vote today at 9:15 on the nomination of Gina McCarthy to be the next EPA Administrator. Despite the fact that she has answered more than a thousand of the committee’s questions, Senate Republicans announced just before the hearing that they would be boycotting the vote, denying the committee quorum and postponing the confirmation hearing.

The committee rules require that at least two members of the minority party be present during a vote. Not a single Republican bothered to show up.

Senator Barbara Boxer, Chair of the committee, still held a meeting, allowing the Democrats in attendance to try to explain to the American people why they still have no EPA Administrator. The ostensible reason that the Republicans boycotted today’s vote was because they said she did not satisfactorily answer their questions. Senator Boxer reminded those present that Gina McCarthy has already answered more than a thousand questions from the committee and moreover is eminently qualified with an excellent track record of working with the business community and and both parties to do her job. Boxer later floated the idea of changing the rules of the committee so that a boycott such as this would not gum up the works. She urged her GOP colleagues to listen to the many “mainstream” Republicans who support Gina McCarthy’s nomination and “get out of the fringe lane.” If senators oppose a nominee, they should show up and vote against the nominee, not hold the process hostage for ideological reasons.

In 2009, the Senate easily confirmed the highly qualified McCarthy by a voice vote to head the Clean Air division of the EPA. With nearly three decades of experience working at the local, state and federal levels, McCarthy has been a champion for clean air and has even won plaudits from Republican leaders. She has received extensive support from business, health officials, environmental organizations and scientists, who have repeatedly suggested she is willing to work with all sides to find the best outcome.

By W.J. Hennigan, Los Angeles Times May 9, 2013

For the first time in its 10 year history, electric car maker Tesla Motors Inc. turned a quarterly profit, beating analysts expectations for sales of its pricey luxury sedans. The Palo Alto automaker on Wednesday reported net income of $11.2 million, or 12 cents a share, in the three month period that ended March 31. That’s up from a loss of $89.9 million, or 76 cents a share, a year earlier. Analysts, on average, had predicted a profit of 4 cents a share. Tesla reported revenue of $561.8 million on record sales of 4,900 of its top-of-the-line Model S sedans. That surpassed the company’s forecast by more than 250 vehicles and prompted the automaker to raise its 2013 forecast. It now expects to sell about 21,000 of its Model S vehicles by the end of this year. “There was a lot of skepticism out there that the company would be able to reach that delivery mark,” said Elaine Kwei, an analyst with Jefferies & Co. “So the fact that they’re raising it — albeit moderately — shows they have visibility to not only hit the mark — but exceeded it. That gives investors additional confidence that the company can hit their targets.” Tesla shares surged in after-hours trading, up nearly $13.91, or 25%, to $69.70. For the quarter, Tesla was the top seller of rechargeable cars in North America, surging past Nissan Motor Co.‘s 3,695 deliveries of the Leaf and General Motors Co.‘s 4,421 sales of the Volt plug-in hybrid. That’s notable considering that Tesla vehicles command premium prices. The Model S starts at about $62,000 and can top $100,000, depending on trim level and options. The car is stylish and fast, boasting a zero-to-60 mph acceleration of less than six seconds. Wealthy, eco-conscious buyers are snapping up the company’s sedans as fast as the company can build them. The company sold 2,650 vehicles in 2012.
