Flooding from high tides has doubled in the US in just 30 years; record levels of “sunny day” or nuisance flooding in 2017

Shoreline communities may be inundated in the next two years as ocean levels rise amid serious climate change concerns 2017 saw an average of six flooding days per area across 98 coastal areas monitored by NOAA – an all-time record by Oliver Milman June 6 2018 Read full Guardian UK article here The frequency of […]


Groundwater pumping can increase arsenic levels in San Joaquin Valley irrigation and drinking water; recovery possible if withdrawals stop

Satellite-derived measurements of ground sinking could predict arsenic concentrations in groundwater and serve as an early warning system to prevent dangerous levels of arsenic contamination in aquifers with certain characteristics worldwide. Researchers found signs that aquifers contaminated as a result of overpumping can recover if withdrawals stop. June 5, 2018 Stanford University Read full ScienceDaily […]


Surprising resurgence of red spruce likely result of cleaner air and warmer winters in US N.E.

Researchers found that reduced acid rain and warmer fall, winter and spring temperatures are leading to the species recovery June 5, 2018 USDA Forest Service – Northern Research Station Read full ScienceDaily article here When scientists found a resurgence of red spruce in northeastern forests, they had a lot of questions. Fifty years ago, red […]


The key triggers of the West’s costly 2017 wildfire season

NASA Earth Observatory

A series of wildfire factors- fuel, aridity, and ignition- culminated in the big burns of 2017. June 5, 2018 University of Colorado at Boulder Read full ScienceDaily article here …Research shows that three major “switches” affecting wildfire — fuel, aridity, and ignition — were either flipped on and/or kept on longer than expected last year, triggering […]


A little water could make a big difference for endangered salmon in coastal Sonoma County (CA)

Less than a gallon per second during dry periods is enough to allow salmon to survive in dry months. This information can drive how riparian restoration is designed to improve fish survival. June 5, 2018 University of California – San Diego Read full ScienceDaily article here Even small amounts of running water — less than […]


California generates more power from solar than gas in May for first time

During May utility-scale solar provided 17% of generation on California’s grid, outpacing gas for the first time on a monthly basis. California was one of only three states in 2017 to get more than 10% of its power from solar. June 4, 2018 Christian Roselund Read full PV Magazine article here In many ways California […]


Hawaii just passed a law to make the state carbon neutral by 2045; most ambitious plan in US

June 5, 2018

The plan is the most ambitious emissions reduction and renewable energy plan of any state in the country. June 4, 2018 Read full FastCompany article In a little less than three decades, Hawaii plans to be carbon neutral–the most ambitious climate goal in the United States. Governor David Ige signed a bill today committing to […]


‘Carbon bubble’ could wipe trillions from global economy; Fossil fuel demand will decline in near future with major economic & geopolitical consequences; need to decarbonise early

Scientists conclude that further economic damage from a potential bubble burst could be avoided by decarbonising early. The study findings support the existence of a carbon bubble which, if not deflated early, could lead to a discounted global wealth loss of between 1 to 4 trillion dollars, a loss comparable to what triggered the 2007 […]
