The world’s oceans are absorbing less carbon dioxide than they were previously as a result of rising anthropogenic CO2 emissions, according to recently completed research by oceanographers at Columbia University’s Lamont-Doherty Earth Observatory.
The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. The researchers estimate...

And the vast majority of this three percent is trapped in glaciers or deep underground chambers, which leaves only a fraction for human consumption or use. The total usable freshwater supply for ecosystems and humans is a mere...
