Surviving on a warming planet can be a matter of timing — but simply shifting lifecycle stages to match the tempo of climate change has hidden dangers for some animals, according to new research. The study has uncovered drastic consequences for birds that are breeding earlier in lockstep with earlier starts of spring: chicks hatching earlier face increased risk of poor weather conditions, food shortages and mortality.
Scientists have spotted a once-in-a-century climate anomaly during World War I that likely increased mortality during the war and the influenza pandemic in the years that followed.
Researchers have predicted how and where the Asian giant hornet, an invasive newcomer to the Pacific Northwest, popularly dubbed the ‘murder hornet,’ could spread and find ideal habitat, both in the United States and globally.
A warming climate and more frequent wildfires do not necessarily mean the western United States will see the forest loss that many scientists expect. Dry forest margins may be more resilient to climate change than previously thought if managed appropriately, according to researchers.
The 2020 minimum extent, which was likely reached on Sept. 15, 2020 measured 1.44 million square miles (3.74 million square kilometers).
