Nature-based solutions can prevent $50 billion in Gulf Coast flood damages– Restoration of marshes and oyster reefs are among the most cost-effective solutions

April 13, 2018

Wetland and reef restoration can yield benefit-to-cost ratios greater than seven to one, meaning more than $7 in direct flood-reduction benefits for every $1 spent on restoration. Future flood risks from coastal hazards will grow, and that the major driver of risk in the Gulf is coastal development, particularly for the most extreme and costly […]

Is it worth paying for carbon offsets next time you fly?

April 12, 2018

Does it work?  Even if you pay, you’re not stopping carbon dioxide produced by your flight from entering the atmosphere. Reduce your number of flights per year. And if you must fly, do research and choose to fly with an airline that has a good emission reduction record. And if your airline doesn’t have a […]

Hotter, longer, more frequent — marine heatwaves on the rise


From 1925-2016, the study found the frequency of marine heatwaves had increased on average by 34% and the length of each heatwave had increased by 17%. Together this led to a 54% increase in the number of marine heatwave days every year. April 10, 2018 University of New South Wales We know heatwaves over land […]

Atlantic Ocean circulation at weakest point in more than 1,500 years; that’s bad news


AMOC conveyor belt

The oceans’ circulation hasn’t been this sluggish in 1,600 years. That’s bad news. The research suggests that the Atlantic Meridional Overturning Circulation (AMOC) has weakened over the past 150 years by approximately 15 to 20 percent. The present-day AMOC is exceptionally weak April 11, 2018 Woods Hole Oceanographic Institution  Read full ScienceDaily article here and […]

Grazing Management to Improve Soil Health- rotational grazing can improve soil health over continuous grazing strategies

April 11, 2018

Proper livestock grazing – which maintains and improves soil health – results in a series of interconnected positive outcomes including: Soil densities and structure that allow root and water penetration of the entire soil profile. Vigorous forage plants with capacity to develop and maintain extensive rooting systems. A community of palatable forage plants with high […]

Birds migrate away from diseases


Immune systems of migratory birds show a similarly low variation to that of European sedentary birds,a surprising result since migratory birds don’t have to resist diseases during breeding and during their migration. To explain the surprising result, the researchers propose the idea that the costs associated with a strong and complex immune system could be […]

One of Europe’s largest lakes has wide range of toxic plastic pollution

April 6, 2018

Freshwater systems have been largely overlooked with regards to the impact of plastic. The impacts of plastic-bound toxic elements on lake wildlife are currently unknown. Researchers detected cadmium, mercury and lead — sometimes in very high concentrations that exceed the maximum permitted under EU law. April 3, 2018 Frontiers Read full ScienceDaily article here The […]

Climate change also threatens the survival of seabirds– new global study with Point Blue co-authors


According to the study, seabirds have not adopted their breeding cycle to the new climate conditions, which are marked by global change. In a future time, the progressive rise of sea temperatures could create a lack of synchrony between the breeding and feeding period and the stages in which preys are more abundant in oceans. […]
