Global team of scientists determine 'fingerprint' for how much heat, drought is too much for forests
University of Florida

A new study, “Global field observations of tree die-off reveal hotter-drought fingerprint for Earth’s forests,” compiled a global database of the published locations of climate-induced forest die-off events, from 1970-2018, across 675 locations. After analyzing the climate conditions at each location during each event, researchers found a common ‘hotter-drought fingerprint’ for Earth’s forests, a term that describes the combination of higher temperatures and more frequent droughts for a lethal set of climate conditions.

UCI researchers first to sample permafrost CO2 emissions during fall and winter
University of California, Irvine

The Arctic is warming along with the rest of the planet, and as this is happening, its permafrost – perennially frozen arctic soil that holds a lot of trapped organic matter from dead plants – is thawing. As the permafrost thaws, the organic matter it holds is thawing, too, and this is opening the door for microorganisms to decompose that matter and, in the process, release climate-warming greenhouse gases like carbon dioxide and methane into the atmosphere.

Study Finds Growing Potential for Toxic Algal Blooms in the Alaskan Arctic
Woods Hole Oceanographic Institution

Changes in the northern Alaskan Arctic ocean environment have reached a point at which a previously rare phenomenon—widespread blooms of toxic algae—could become more commonplace, potentially threatening a wide range of marine wildlife and the people who rely on local marine resources for food. That is the conclusion of a new study about harmful algal blooms (HABs) of the toxic algae Alexandrium catenella being published in the journal Proceedings of the National Academy of Science.

A new study predicts that any sea level rise in the world’s most southern continent will be countered by an increase in snowfall, associated with a warmer Polar atmosphere. Using modern methods to calculate projected changes to sea levels, researchers discovered that the two ice sheets of Greenland and Antarctica respond differently, reflecting their very distinct local climates.

New Study Finds Emperor Penguins Increasingly Threatened by Climate Change
Woods Hole Oceanographic Institution

Woods Hole, MA (August 3, 2021) – A new study published today in Global Change Biology provides valuable new data that highlights how species extinction risk is accelerating due to rapid climate change and an increase in extreme climate events, such as glacial calving and sea ice loss. The study, led by Stephanie Jenouvrier, associate scientist, and seabird ecologist at Woods Hole Oceanographic Institution, and co-authored by an international team of scientists, policy experts, ecologists, and climate scientists, provided pivotal research and projections tailored for use by the U.S Fish & Wildlife Service (USFWS). Their work proposed that emperor penguins be listed as threatened under the Endangered Species Act and this week, USFWS submitted that listing proposal.

Catastrophic Sea-Level Rise from Antarctic Melting is Possible with Severe Global Warming
Rutgers University-New Brunswick

The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, according to a Rutgers coauthored study. But if global warming exceeds the target – 2 degrees Celsius (3.6 degrees Fahrenheit) – the risk of ice shelves around the ice sheet’s perimeter melting would increase significantly, and their collapse would trigger rapid Antarctic melting. That would result in at least 0.07 inches of global average sea-level rise a year in 2060 and beyond, according to the study in the journal Nature.
