Not all clouds are the same, and climate models have been predicting the wrong kinds of clouds over the Southern Ocean. Kathryn Moore

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.

Video: How simple math can help predict the melting of sea ice

Understanding sea ice loss requires expensive and difficult expeditions. Scientists have developed a new model that predicts the growth of small ponds on sea ice more efficiently.

Why Cape Town’s drought was so hard to forecast

Cape Town promised alternative water sources with the ongoing drought being declared a disaster. Its main strategy is water rationing but climate models are also being used.

Climate models too complicated? Here’s one that everyone can use

Climate models are complicated - and necessarily so if they are to recreate our complex world. But a new, simpler climate model aims to take some of the mystery out of the art of climate modelling.

Climate meme debunked as the ‘tropospheric hot spot’ is found

Climate models have been criticised because observations could not find the predicted "hot spot" of strong warming in the troposphere. But analyses now show that the tropospheric hot spot is indeed real.
