Permafrost soil warming

Global warming is leaving more and more apparent scars in the world’s permafrost regions. As the new global comparative study conducted by the international permafrost network GTN-P shows, in all regions with permafrost soils the temperature of the frozen ground at a depth of more than 10 meters rose by an average of 0.3 degrees…

Antarctic ice sheet could suffer a one-two climate punch

Writing this week (Jan. 14, 2019) in the journal Nature Geoscience, a team led by Richard Levy of New Zealand’s GNS Science and Victoria University of Wellington, and Stephen Meyers of the University of Wisconsin-Madison describes research that matches the geologic record of Antarctica’s ice with the periodic astronomical motions of the Earth. Comparing the…

Upper-ocean warming is making waves stronger

Sea level rise puts coastal areas at the forefront of the impacts of climate change, but new research shows they face other climate-related threats as well. In a study published January 14 in Nature Communications, researchers report that the energy of ocean waves has been growing globally, and they found a direct association between ocean…

Ocean warming is accelerating

Wild fires. Severe storms. Record breaking rains. Heat waves. All occurred in abundance in 2018, and 2018 is shaping up to be the hottest for the oceans as a whole, and therefore for the Earth, in the instrumental record. Global warming is here, and has major consequences already. There is no doubt, none! On January…

How the fossil fuel industry got the media to think climate change was debatable

George H.W. Bush identified as an environmentalist and called for action on global warming, framing it as a technological challenge that American innovation could address. But fossil fuel interests were shifting as the industry and its allies began to push back against empirical evidence of climate change, taking many conservatives along with them. Documents uncovered…

Kauai at 50% renewable power

The 28-megawatt solar farm on the south shore of the Garden Isle includes a first-of-its-kind design that transfers power from the sun to batteries and onto the power grid more efficiently than other existing storage systems, AES Chief Executive Officer Andres Gluski said Tuesday in an interview. That allows the Lawai Solar and Energy Storage…

Local governments spend to protect against climate change

Frustrated by what they see as the Trump administration’s decision to de-emphasize the danger posed by climate change, local government officials, non-profit leaders and university researchers are busily forging ahead with limited resources in a piecemeal approach they say is better than nothing. They’re hardening buildings, digging bigger storm drains and changing zoning laws to…

Tidal flat ecosystems are being lost

Scientists from the University of New South Wales (UNSW) and the University of Queensland used machine-learning to analyse more than 700,000 satellite images to map the extent of and change in tidal flats around the globe. The study, published in Nature, found tidal flat ecosystems in some countries declined by as much as 16% in…

EPA Weakens Basis for Calculating Mercury and Future Environmental Standards

According to New E.P.A. Plan Could Free Coal Plants to Release More Mercury Into the Air as reported by The New York Times: In the proposal, the Environmental Protection Agency issued a finding declaring that federal rules imposed on mercury by the Obama administration are too costly to justify. It drastically changed the formula the…

Unprepared For Sea Level Rise

Each year, $500 million worth of coastal structures are lost as coastlines disappear. The federal government spends nearly $150 million each year to manage the loss of beaches and coastal real estate. Two-thirds of the U.S. population lives and works in coastal counties. Ocean-related businesses are responsible for over $352 billion of the U.S.’ annual…
