Biological production of this greenhouse gas, once thought to be the reserve of anaerobic microbes, occurs in these widespread, photosynthesizing cyanobacteria.

As global temperatures rise and winters shorten, caterpillars of the corn borer moth are emerging earlier in parts of the US thanks to changes in two genes, researchers find.

The wildfires burning across Australia have caused significant damage to ecosystems and vulnerable species, yet some are faring worse than others.

The new experiments use standardized methods and video recordings, but some researchers stand by earlier evidence that ocean pH influences coral reef fish’s response to predator cues.

A mass death event claimed the hominins’ lives and likely resulted from changing environmental conditions.

The animals have a smaller body mass, shorter legs, and longer wings than they did four decades ago.

Chinstrap penguins are decreasing in numbers due to a lack of krill, their only food source.

From 1969 to 1988, 25,000 infants were born early each year as a result of hot weather, and with global warming pushing temperatures higher, more babies will be at risk for early birth.

Carbon dioxide and temperature need to increase in a constant ratio for plants to keep up with climate change.
