WASHINGTON — Earth just broiled to its hottest month in recorded history, according to NASA.
Even after the fading of a strong El Nino, which spikes global temperatures on top of man-made climate change, July burst global temperature records.
WASHINGTON — Tempers are rising in America, along with the temperatures.
WASHINGTON — It’s the early bird that gets the Cheetos. But it’s the bigger bird that steals it away.
Behavioural ecologist Rhea Esposito used the snack food to see how two types of smart birds smaller magpies and bigger crows interact and compete for food.
WASHINGTON — Scientists now calculate that Greenland sharks are Earth’s oldest living animals with backbones.
They estimate that one of those grey sharks was born in icy Arctic waters roughly 400 years ago and lived until only a couple of years ago.
WASHINGTON — A new study clearly connects rising temperatures to increases in waterborne food-poisonings and other infections.
WASHINGTON — Flying through dangerous cold and pitch-dark, a small plane is making a 1,500-mile trip to evacuate a sick worker from a remote U.S. science station on the South Pole.
WASHINGTON — For a long time, the debate has gone on: Does size matter to females? Biologists now say, definitively, that it does.
Among fruit flies.
WASHINGTON — A new discovery about how clouds form may scale back some of the more dire predictions about temperature increases caused by man-made global warming.
That’s because it implies that a key assumption for making such predictions is a bit off.
WASHINGTON — The amount of heat-trapping carbon dioxide in the air jumped by the biggest amount on record last month, a rise amplified by El Nino, scientists say.
