How anchoring a ship to an ice floe will help fight climate change

In September, the giant German polar research vessel Polarstern will set off from Tromsø in Norway on a remarkable voyage. It will sail across the Arctic Ocean and after a few weeks reach a point off the Siberian coast, around 85 deg N 120 deg E, where it will attach itself to the biggest, strongest-looking ice floe its crew can find.

Why the Guardian is putting global CO2 levels in the weather forecast

As CO2 levels climb, the carbon count is a daily reminder we must tackle climate change now. The simplest measure of how the mass burning of fossil fuels is disrupting the stable climate in which human civilisation developed is the number of carbon dioxide molecules in the atmosphere.

Extreme CO2 levels could trigger clouds ‘tipping point’ and 8C of global warming

If atmospheric CO2 levels exceed 1,200 parts per million (ppm), it could push the Earth’s climate over a “tipping point”, finds a new study. This would see clouds that shade large part of the oceans start to break up.
