Warm waters run very deep.
The prospect of attempting to engineer the world's climate has become a lot more real since the Paris Agreement.
Tony Abbott was being his old pre-prime-ministerial self on Monday, with a full-on speech to a climate sceptics group in London.
Speaking in a light and bright FM radio interview on Tuesday, Malcolm Turnbull said that in politics, “just being chilled, calm is very important. A little bit of zen goes a long way.” He was answering…

Without limiting global warming Europe is likely to see more severe heatwaves, less frequent extreme cold and more intense rain events.

Europeans are, on average, more likely than Americans to say they fear climate change. What explains the gap?
The window for staving off the worst of climate change is wider than we thought, but still pretty narrow.
It's still possible to hit the more ambitious of the two Paris global warming goals, according to a new estimate of the global carbon budget. But it sure won't be easy, and we need to start now.
Sea ice trapped atmospheric carbon dioxide in the last ice age.
The last ice age locked atmospheric carbon dioxide into oceans, which has major implications for how the oceans and carbon dioxide may be linked in the future.
This winter had some extreme low and high temperatures.
In 2017 Australia's winter had the highest average daytime temperatures on record. This extreme is 60 times more likely to occur under the influence of greenhouse gas emissions.
Algae could be the key to a new type of biofuel.
The right kind of algae can be converted to biofuel, and there are potential side benefits for carbon capture.

Unlike the more abstract idea of global climate change, pollution is tangible and its effects are obvious.
When is it too hot to fly?
Major airports around the world will see more frequent flight restrictions in the coming decades because of increasingly common hot temperatures.

The globe is greening as plants grow faster in response to rising carbon dioxide. But a new analysis shows they aren't using more water to do it - a rare piece of good news for our changing planet.
What does the shrinking of the Colorado River mean for Native American religions?
Historically, indigenous peoples used the natural seasonal cycles of weather, plants and animals as part of their religious calendar. What will be the impact of climate change on their practices?
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.
Best-case scenario, how much are we locked into?
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
Protests at the Brandenburg Gate, in Berlin, against the US withdrawal from the Paris climate change deal.
An expert report shows that the G20 countries are using their energy more efficiently. But there is still a long way to go.

Action on climate change is now increasingly in China's hands, and the decisions the country's leaders make in the next decade will have a profound global impact.
Water mass enters the ocean from glaciers such as this along the Greenland coast.
Greenland's ice is largely responsible for the accelerating pace of sea-level rise. A new analysis shows that, while Greenland accounted for just 5% of the rise in 1993, that figure rose to 25% by 2014.
Solar radiation management involves spraying tiny reflective particles into the upper atmosphere to reflect away some of the energy from the sun
Solar radiation management might be able to reduce some of the risks of global warming while countries get their emissions under control.
Diversity, resilience, resistance to disease: seeds must be preserved to ensure we can feed our world in the future.
