Clouds can act as both blanket and parasol – warming our atmosphere at the same time as cooling it. But which effect will dominate?
Not all clouds are the same, and climate models have been predicting the wrong kinds of clouds over the Southern Ocean.
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.
The new model predicts the growth of small ponds on arctic ice sheets.

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.

The new values are a worrying outcome that no one wants, but one we must still grapple with.

Humanity at risk if we keep thinking everything is under control
Reducing pollution will help stave off climate change but avoiding the worst effects means taking CO2 out of the atmosphere at large scale.

Countries are not on track to meet Paris Agreement goals. A climate researcher argues that a range of technologies that take CO2 out of the air are needed.

New research addresses two questions about the supposed 'pause' in warming.
Clouds roll across Samosir in northern Sumatra.
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.
MiMA: an open source way to model the climate.
The creation of climate models with open source code, available for anyone to use, has improved scientific collaboration and helped research get more efficient.
Cape Town’s drought and associated water shortage has escalated disaster level.
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.
A new paper improves our estimate of the climate’s sensitivity to carbon dioxide.
A new analysis suggests that weather records have not yet had time to capture the full effects of climate change, some of which are likely to take centuries to play out.
CSIRO’s decision a decade ago to merge its marine and atmospheric research set the stage for a national climate research plan.
CSIRO was instrumental in creating a unified plan for all of Australia's climate research. The latest round of cuts would see that collaboration fall apart.
Simpler climate models could help more people understand the processes behind the predictions.
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.
Gathering data at the calving front of the Ilulissat Glacier, Greenland.
To create accurate models that predict how ice sheets and oceans will react to changing climate, modelers need precise current data. One researcher heads to the ends of the earth to collect just that.
Even another 85 years of global warming won’t stop the odd cold, snowy winter.

While global warming will continue, it's important to assess variability as well as long-term average climates.
A new analysis of historic weather balloon data reveals that the troposphere has been warming as climate models predicted.
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.
