Scientists need to be comfortable dealing with subjective views, rather than empirical data, and people’s feelings to make progress in addressing climate change.

Things can change disturbingly quickly – just ask the people who once farmed the Sahara.
Melting ice means sea levels will rise…but how fast?

Since scientists are the real sceptics, they still argue a lot among themselves.

The Millennium Drought was bad, but the most detailed record of droughts since 1500 reveals there were far more severe super-droughts in the past.
Extreme weather is more common than ever.

2015 will likely be the hottest year on record, according to a preliminary analysis released by the World Meteorological Organization.
Yep…still melting.

There’s no agreed definition, no agreed starting point – and no data to back it up.
It’s no wonder people are sometimes confused about science.

Research shows how the the tobacco and fossil fuel industries used different tactics to undermine scientific consensus.
Even if Exxon eludes charges in New York, the attorney general’s investigation sends a message on corporate accountability.

2014 saw heatwaves of all kinds and other wild weather. Research can now explain that climate change made these events much more likely.

This has been Australia’s hottest October on record. And the record-breaking temperatures are at least six times more likely thanks to human-induced global warming.
Replanting forests is one way to remove carbon dioxide from the atmosphere. This is a site in China.

New research shows that we’ll have to remove carbon from the atmosphere for any chance of keeping warming below 2C.
The Southern Ocean is remote, cloudy – and full of plankton.

These tiny organisms play a big role in regulating the Earth’s climate.
London’s ‘frost fairs’ are a thing of the past – not the future.

Any drop in solar activity will be dwarfed by the impact of increased carbon dioxide in the atmosphere.

Stalagmites in Scottish preserve 3,000 years of climate history, suggesting human migration is linked to wet and dry periods.

We’ve never had multi-year seasons here on Earth, but long cold spells might be similar to a Westerosi winter.
The threat of an El Niño has not gone away for Australia.

This last year we were preparing for an El Niño. But then it all just fizzled out. So what happened? And could this be the year?
Another way to change the carbon balance: trees.

Divestment campaigns aim to halt the use of fossil fuels, but the climate can be also stabilized through ‘recarbonization’ techniques, such as reforestation and changing agricultural practices.
