Antarctica's Climate Much Warmer During Interglacials Than Once Thought

A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages (interglacials) may have been higher than previously thought. The latest analysis of ice core records suggests that Antarctic temperatures may ...

Warming Oceans Losing Ability To Absorb CO2, Geophysicist Says

As the world's oceans warm, they are absorbing less carbon dioxide, a new study in the November 25 issue of Geophysical Research Letters has found.  With the oceans currently absorbing over 40 percent of the CO2 emitted by human activity, this could q ...

What's Up With Climate Change And The Ozone Hole?

Yes, what's up! Here we go. Climate change and ozone depletion affect one another in complicated ways. In simple terms, "the ozone hole" pertains to the Southern Hemisphere. However, reductions in ozone content in the stratosphere above the ...

Study Predicts Warming In Antarctica As Ozone Layer Recovers

Thanks to compliance with the Montreal Protocol, the ozone layer is beginning to recover and that means Antarctica is about to experience more warming and an increase in snowmelt, a new study in Geophysical Research Letters predicts. Based on space-borne m ...

Are Scientists Underestimating Earth's Sensitivity To CO2?

A study appearing in Nature Geoscience this week claims that Earth's temperature may be 30-50% more sensitive to atmospheric carbon dioxide than previous estimates suggest, and the effects of this increased sensitivity could make climate change an eve ...

Earth's Atmosphere Likely Came From Outer Space

A team of scientists has detected tiny quantities of the unreactive volcanic trace gases Krypton and Xenon in Earth's mantle, which reveal an isotopic 'fingerprint' matching that of meteorites. The researchers say this means the gases that f ...

Earth's Atmosphere Came From Outer Space, Not Volcanoes, Say Scientists

The gases which formed the Earth's atmosphere and probably its oceans did not come from inside the Earth but from outer space, according to a study by University of Manchester and University of Houston scientists. The report in Science claims that tex ...
