The movements of water within the ocean basins has been increasing in speed over the last 20 years, a new study shows, conflicting with prior models of climate change.
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 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.
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.
The concentration of the greenhouse gas is now one-and-a-half times what it was before the Industrial Revolution, the World Meteorological Association says.
