North American cold-climate forests are already absorbing less carbon, study shows
Trees are one of humans' biggest allies in the fight against climate change, soaking up around 30% of the carbon we pump into the...
Findings refute idea of monarchs’ migration mortality as major cause of...
In a new study, Monarch Watch Director Chip Taylor and colleagues have shown that speculation regarding the declining monarch population, despite having received much...
The tropics are expanding, and climate change is the primary culprit
Earth's tropics are expanding poleward and that expansion is driven by human-caused changes to the ocean, according to new research.
The tropics wrap around Earth's...

Exploding stars may have caused mass extinction on Earth, study shows
Imagine reading by the light of an exploded star, brighter than a full moon—it might be fun to think about, but this scene is...
A stepping stone for measuring quantum gravity
A group of theoretical physicists, including two physicists from the University of Groningen, have proposed a 'table-top' device that could measure gravity waves. However,...
Recent global warming trends are inconsistent with very high climate sensitivity
Research published this week in Earth System Dynamics reports that the most sensitive climate models overestimate global warming during the last 50 years.Three scientists from the...
Flies and mosquitoes beware, here comes the slingshot spider
Running into an unseen spiderweb in the woods can be scary enough, but what if you had to worry about a spiderweb—and the spider—being...
How a protein stops cells from attacking their own DNA
Viruses multiply by injecting their DNA into a host cell. Once it enters the intracellular fluid, this foreign material triggers a defense mechanism known...
Restoring degraded tropical forests generates big carbon gains
More than half of the world's aboveground carbon is stored in tropical forests, the degradation of which poses a direct threat to global climate...
