Did global warming delay a new Ice Age?
Shall we call it the upside of global warming?
If researchers are correct, then elevated levels of carbon dioxide linked to human emissions has helped put off the next Ice Age. Their article, published in the journal Nature Geoscience, argues that the next Ice Age was slated to begin approximately 1,500 years from now. "At current levels of CO2, even if emissions stopped now we'd probably have a long interglacial duration determined by whatever long-term processes could kick in and bring [atmospheric] CO2 down," according to Luke Skinner from Cambridge University.
Earth's last Ice Age ended about 11,500 years ago.
According to the researchers' calculations, the Earth's atmospheric concentration of CO2 would need to drop below 240 parts per million before the process of glaciation could kick in. The planet's current level is around 390ppm.
