Critical turning point can trigger abrupt climate change
Ice ages are the greatest natural climate changes in recent geological times. Their rise and fall are caused by slight changes in the Earth's orbit around the Sun due to the influence of the other planets. But we do not know ...

Global monsoon drives long-term carbon cycles in the ocean
Monsoon is a global system, and many arrays of evidence indicate that it drives long-term cyclicity of the carbon reservoir in the global ocean. The new view is introduced in a substantial paper in Issue 7 (April 2009) of ...

Warmer than a Hot Tub: Atlantic Ocean Temperatures Much Higher in the Past
Scientists have found evidence that tropical Atlantic Ocean temperatures may have once reached 107°F (42°C)—about 25°F (14°C) higher than ocean temperatures today and warmer than a hot tub.

Antarctic iced over when greenhouse gases – not ocean currents – shifted, study suggests
A longstanding theory that provides much of the basis for our understanding of climate change – that the mile-thick ice sheet covering Antarctica developed because of a shift in ocean currents millions of years ...
