We caught bacteria from the most pristine air on earth to help solve a climate modeling mystery

Climate models have been overestimating how much sunlight hits the Southern Ocean. This is because the clouds there are different from clouds anywhere else. Bacterial DNA helped us understand why.
During the Pliocene, up to one third of Antarctica’s ice sheet melted, causing sea-level rise of 20 metres. from www.shutterstock.com

If warming exceeds 2°C, Antarctica’s melting ice sheets could raise seas 20 metres in coming centuries

New research shows that warming by more than 2°C could be a tipping point for Antarctica's ice sheets, resulting in widespread meltdown and changes to the world's shorelines for centuries to come.

Britain’s industrial pioneers couldn’t have known how they would affect the climate. Henry Gastineau

The Industrial Revolution kick-started global warming much earlier than we realised
