Global emissions almost back to pre-pandemic levels after unprecedented drop in 2020, new analysis shows

Most concerning is the long-term upward trends of CO₂ emissions form burning fossil fuels, which are far from trending towards net-zero by 2050.

Peatlands worldwide are drying out, threatening to release 860 million tonnes of carbon dioxide every year

Peatlands worldwide are running short of water, and the amount of greenhouse gases this could set loose would be devastating for our efforts to curb climate change.

New research shows global CFC emissions are declining

New research shows global CFC-11 emissions, which unexpectedly and concerningly began to rise in 2013, are lowering once again.

Global emissions are down by an unprecedented 7% — but don’t start celebrating just yet

The pandemic, along with other recent trends such as the shift towards clean energy, have placed us at a crossroad: the choices we make today can change the course of global emissions.

Turning methane into carbon dioxide could help us fight climate change

In a paper published today in Nature Sustainability, we propose a new technique to clean the atmosphere of the second most powerful greenhouse gas people produce: methane. The technique could restore the concentration of methane to levels found before the Industrial Revolution, and in doing so, reduce global warming by one-sixth.
