Mixing waters may hasten arrival of ice-free Arctic Ocean summers
In yet another sign that the balance of Earth’s climate system is being perturbed by global warming, scientists are documenting how a steady intrusion of water from the Atlantic is undermining sea ice in the Arctic Ocean.
Freezes, fires and tornadoes caused significant regional economic harm in Jan.-March

Tornadoes, wildfires, and blizzards during the second-warmest winter on record for the U.S. killed 37 people and caused an estimated $5.8 billion dollars in damage, according to the latest monthly update from federal climate trackers at the National Oceanic and Atmospheric Administration.
Study looks at hybridization of trout in Northern Rocky Mountains
Global warming is intensifying the hybridization of native and non-native trout in the northern Rocky Mountains, according to a new study from the U.S. Geological Survey and other scientists. The trend is a serious threat to the biodiversity of Rocky Mountain aquatic ecosystems, says the study published in the journal Global Change Biology.
Study shows how coffee plants suffer even during short heatwaves
Heatwaves are becoming more common in a world warmed by heat-trapping greenhouse gas pollution, and at some point in the not-too-distant future, that could spell bad news for your morning cup of wake-me-up.
Scientists with Oregon State University’s College of Forestry have showed that, when Coffea arabica plants were subjected to short-duration heat waves, they became unable to produce flowers and fruit. That means no coffee beans, and no coffee to drink.
Skiers have as much to lose as anyone. Glaciers are shrinking everywhere, overall there is less snow and winters are getting shorter at both ends, but especially in the spring. In a groundbreaking 2013 study, the U.S. Geological study found a 20 percent decline in Rocky Mountain snow cover since 1980.
Another research paper published just this year in meticulous Swiss fashion documented that the snow season has shortened by 37 days since 1970, with a 25 percent decline in the average maximum snow depth across the entire Swiss Alps, at all elevations. The researchers were surprised to find the decline even at the higher mountain weather stations close to famous resorts like Zermatt and Davos.
Anti-environmental agency head may have violated EPA policies and lied to Congress under oath
By Bob Berwyn
There’s little question that Scott Pruitt is the worst possible person to lead the EPA. He’s been involved in more than a dozen lawsuits against the agency and he’s called for it to be abolished completely, so it’s no surprise that he’s a target for bitter criticism from conservation groups. But his troubles are about to get much bigger than indignant tweets.
The Sierra Club has filed a formal complaint with the Inspector General of the Environmental Protection Agency demonstrating that EPA Administrator Scott Pruitt has violated the Agency’s Scientific Integrity Policy in multiple ways. The filing calls for an investigation into and resolution of Pruitt’s comments on carbon dioxide’s role in fueling the climate crisis.
