Llamas could help replenish plant life after glaciers retreat
The rapid retreat of glaciers from alpine regions around the world could result in widespread ecosystem losses, according to new research. Now, scientists are exploring a hairy solution to this hairy problem in the form of llamas.

Wildfire residue may contribute to climate change
Wildfires leave behind large swathes of blackened earth when they raze a landscape. That charred material contains a host of molecules that could continue to release carbon dioxide into the atmosphere days and weeks after the fire has gone out, according to new research.

Can Arctic ‘ice management’ combat climate change?
Both sea ice retreat and global warming could be slowed by millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter. Researchers have now, for the first time, tested the concept using a complex climate model.

New study models impact of calving on retreat of Thwaites Glacier
A new study in the AGU journal Geophysical Research Letters modeled how much faster Thwaites, one of West Antarctica’s largest and fastest-retreating glaciers, would retreat in the absence of its ice shelf — the part of the glacier that floats on top of the sea, supporting the thicker ice behind…“Worst-case scenario, it is going to be gone in less than a century. But it may also take much longer.”

Advancing spring warmth could disrupt species migration, development
In a new study in the AGU journal Geophysical Research Letters, scientists found that in many areas of the U.S. springtime temperature thresholds important for plant and animal life cycles occur between six to 20 days earlier in the season than they did 70 years ago.

Study Tallies Huge Hidden Health Costs from Climate Change
Research sheds light on public health impact from climate-related events, spotlight on CO, FL, MI, NV, NJ, NY, NC, OH, TX, WA, and WI.

Researchers find new ways for coral reef ecosystems to grow
Particulate organic matter from the open ocean has a bigger-than-expected role in the growth and health of coral reefs, say researchers studying declining coral reefs in Hawaii.

Upper Nile will experience more water scarcity due to hotter, drier periods
An increase in hotter, drier years in the coming decades due to climate change may worsen water scarcity issues in the Upper Nile Basin. These impacts are likely to cause an increase in agricultural failure in Ethiopia and may potentially lead to civil strife, according to the authors of a new study published in Earth’s Future, a journal of the American Geophysical Union.

Climate change is altering winter precipitation across the Northern Hemisphere
A team of scientists has successfully teased out the influence of human-caused climate change on wintertime precipitation over much of the last century, showing that the warming climate is significantly altering wintertime rainfall and snowfall across the Northern Hemisphere.

Unprecedented 2018 Bering Sea ice loss repeated in 2019
Sea ice in the Bering Sea reached record-low levels during winter 2018, thanks to persistent warm southerly winds. These conditions caused the ice to retreat to the northern reaches of the 800,000 square mile body of water. By the end of April 2018, sea ice was about 10 percent of normal. And then, much to scientists’ surprise, 2019 just missed eclipsing the record set in 2018.
