Climate sensitivity – reducing the uncertainty of uncertainty

New research aims at making climate change prediction more accurate.

Global warming is a reality – but just how bad will it be? A study published in January 2018 claims to halve the uncertainty around how much our planet’s temperature will change in response to rising carbon dioxide (CO2) levels, potentially giving governments more confidence to prepare for the future. The results suggest that, when it … Read more

Warmer, saltier polar water could change global ocean currents

When ice shelves melt, they dump freshwater into the sea which lightens the salty water.

Melting ice shelves are changing the ocean’s chemistry at the South Pole and the result could be a change in global currents and increased glacial melt, according to scientists who are creating maps to feed into climate change models. At the North and South Poles, cold dense water sinks, powering the so-called global ocean conveyor belt, … Read more
