Europe, North America and east Asia can expect more cold, moist and snowy winters such as the one just passed, a top scientist said Friday.
For more than a century scientists have known that Earth's ice ages are caused by the wobbling of the planet's orbit, which changes its orientation to the sun and affects the amount of sunlight reaching higher latitudes, ...
Parts of ancient Antarctica were as warm as today's California coast, and polar regions of the southern Pacific Ocean registered 21st-century Florida heat, according to scientists using a new way to measure past temperatures.
Millions of people in northern Europe are still battling snow and ice, wondering why they are being punished with bitter cold when—officially—spring has arrived and Earth is in the grip of global warming.
