After three years in which global carbon emissions scarcely rose, 2017 has seen them climb by 2%, as the long-anticipated peak in global emissions remains elusive.
Who will emerge as the leader on climate change following the U.S. withdrawal from the Paris agreement?

Canada ratified the Paris agreement on climate change, but it hasn’t yet filled the leadership void left by the United States. Time is running out.
Sunrise over the Earth. Hydrofluorocarbons were created to protect the ozone layer, but their stable nature makes them an extremely potent greenhouse gas.

Australia has ratified an agreement to phase out hydrofluorocarbons, a manmade compound once hailed as the saviour of the ozone layer. What went wrong?
Human activity, along with a strong El Nino, drove 2016 greenhouse gas levels to new heights.

Global greenhouse gas levels have hit their highest point in at least 3 million years, according to new figures from the World Meteorological Organisation.
The federal government has announced a new National Energy Guarantee focused on electricity reliability, after deciding not to implement a clean energy target.

The amount of atmospheric energy available to thunderstorms will increase in response to climate change, putting the tropics and subtropics at risk of being lashed with more intense storms.

New data from a NASA satellite show in unprecedented detail the flow of carbon dioxide into the atmosphere. Future satellites should even be able to detect the signatures of individual power stations.
A nuclear blast and runaway climate change could propel us into the Plutocene.

Imagine a world ravaged by the fallout from nuclear weapons and the runaway effects of climate change. Congratulations, you’ve just imagined the Plutocene, but let’s hope it doesn’t become a reality.
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.
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.
So large are the nation’s daily greenhouse gas emissions that if yours is a typical Australian lifestyle you’re contributing disproportionately to climate change.

It would take a lifestyle upheaval to drop most Australians’ household emissions to a sustainable level. Even many of us who urge equitable action on climate change act as if this doesn’t apply to us.
Methane is produced in landfill when organic waste decomposes.

Landfills produce huge amounts of methane. Many of the bigger operators capture it to turn into energy, but they’re wasting about 80% of what’s available. It’s time Australia stepped up.
Tonight on the ABC’s Catalyst, scientist Tim Flannery asks if seaweed can save the world. It’s a bold claim for algae, but seaweed could play a key role in keeping climate change in check.
Australia will need more sources of zero-emissions energy if it is to stay on track for carbon-neutrality by 2050.

A new analysis by ClimateWorks Australia says that the electricity sector needs to do far more to cut its carbon emissions than will be delivered by current policies.
There have been successive large scale droughts in East Africa.

Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?

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.
