CO2 pulses and the last Ice Age
October 30, 2014 12:34 PM - Oregon State University

A new study shows that the rise of atmospheric carbon dioxide that contributed to the end of the last ice age more than 10,000 years ago did not occur gradually, but was characterized by three “pulses” in which C02 rose abruptly.

Scientists are not sure what caused these abrupt increases, during which C02 levels rose about 10-15 parts per million – or about 5 percent per episode – over a period of 1-2 centuries. It likely was a combination of factors, they say, including ocean circulation, changing wind patterns, and terrestrial processes.

The Aral Desert: Once a Sea - Now, All Dried Up

Anson Mackay, The Ecologist

The Aral Sea is a well known environmental disaster zone. But this year, it got a whole worse, writes Anson Mackay, as its biggest basin dried up completely to expose a toxic, salty wasteland. With continuing irrigation and declining river flows due to climate change, the desert is only set to expand. The Aral Sea has reached a new low, literally and figuratively. New satellite images from NASA show that, for the first time in its recorded history, its largest basin has completely dried up. However, the Aral Sea has an interesting history - and as recently as 600-700 years ago it was as small, if not smaller, than today.
