Back when there were Arctic alligators and turtles, ‘polar stratospheric clouds’ kept their world warm. Research suggests these clouds contribute to the ‘missing warming’ in climate models.

Evidence in Earth’s natural archives, from tree rings to seafloor sediments, points to one trend. Some climate models suggest another.
The current estimate is that Earth would warm by 1.5°C to 4.5°C if emissions were to double on pre-industrial levels. The range has remained stubbornly wide, despite improved climate modelling.
An article in the eminent US magazine Science has triggered debate over whether scientists should use climate models. Here’s what you should know about climate models ahead of today’s IPCC report.
Climate change is strengthening the division between the ocean surface and the abyss.
In a bid to ditch fossil fuels, some countries are considering carpeting deserts with solar panels.
Peat beds around the world hold huge quantities of carbon and keep it from warming the planet. But rising temperatures and over-use could turn them from a brake on climate change into an accelerant.
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.
Despite its global importance, the rainy ‘Maritime Continent’ around Indonesia is hard to capture using global climate models. But fear not - new research shows how to improve our forecasts.
