2015 looks set to be the hottest year on record.
2015 will likely be the hottest year on record, according to a preliminary analysis released by the World Meteorological Organization.
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.
Until now, the legal system has tolerated corporate deceptions of the public but New York state's investigation into Exxon on climate could start to rewrite the rules.

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.

Loss of sea ice near Greenland and Iceland portend a colder future for Europe.

Stalagmites in Scottish preserve 3,000 years of climate history, suggesting human migration is linked to wet and dry periods.
Someone knit this young man a nice woolly hat.
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.
Out of sight out of mind? The vast majority of global warming is going into the ocean.
Over the past decade, warming air temperatures at Earth's surface appear to have slowed. But that ignores the vast majority of heat going steadily into the ocean. And, a new paper shows, that makes no difference to the long-term prognosis.
Clumps of thunderstorms are driving increases in rain over tropical oceans.

For a long time climate models have forecast increasing rainfall in tropics. Now we know part of the reason: clumpy thunderstorms.
Everything is more interesting with colourful lights.
Sometimes it's fine for climate science to be plain old interesting.
If we’re going to mess with the weather, better know what we’re doing first.
The publication of a hefty two-volume report on geoengineering by the US National Research Council represents a marked shift in the global debate over how to respond to global warming. To date, the debate…
Carbon dioxide levels are rising at their fastest rate since the dinosaurs’ time.
The latest climate projections released last week by the Bureau of Meteorology and CSIRO predict that Australia could potentially warm by between 2.8C and 5.1C by 2090. Meanwhile, the 2014 State of the…
Researchers deploy robotic Argo floats into the ocean to measure temperature.
The oceans are continuing to warm steadily despite an apparent slowdown in global warming at the earth’s surface, according…
