Releasing reflective particles into the upper atmosphere would help us tackle climate change – but it’s not without risk.
The world is on track to exceed 2°C warming within the next five years, with dire consequences for polar ice, mountain glaciers and permafrost – and human society.
While a seemingly remote and unfamiliar landscape, the Arctic shares many surprising similarities with contemporary Canadian cityscapes.
Large stretches of the Arctic are carbon-rich peat bogs. As the region warms and dries, lightning strikes can spark underground fires that can burn for years.
DNA frozen for 2 million years paints a picture of an extinct ecosystem.
A Pandoravirus has been revived after remaining dormant in the Siberian permafrost for nearly 50,000 years.
Ground is collapsing and massive lakes are draining in a matter of days. Thawing permafrost is having profound effects on the region and its infrastructure.
The growing season on the tundra is starting earlier as the planet warms, but the plants aren’t sequestering more carbon, a new study finds.
Permafrost in the Yukon is a treasure trove of ancient environmental DNA, but climate change threatens these rich historical archives.
Sea ice is thinning at an alarming rate. Snow is shifting to rain. And humans worldwide are increasingly feeling the impact of what happens in the seemingly distant Arctic.
Alaska is warming faster than any other U.S. state, and that’s causing problems, a team of bridge engineers and social scientists explains. The infrastructure bill in Congress would offer some help.
Earth observation satellites can measure millimetre changes in sea level and track deforestation in near-real time.
Australia must treble its emissions reduction targets and reach net-zero emissions by 2035. Without this and other radical global action, the chance to hold warming to well below 2°C will pass us by.
New research shows that permafrost contains huge amounts of particles that make it easier for cloud moisture to freeze. Thawing permafrost is releasing these ice-nucleating particles.
Peat beds around the world hold huge quantities of carbon and keep it from warming the planet. But rising temperatures and over-use could turn them from a brake on climate change into an accelerant.
Three scientists describe the fieldwork they’ve had to delay in 2020 because of the pandemic. These are setbacks not just for their careers, but for the body of scientific knowledge.
The Zimovs want to restore the prehistoric ‘mammoth steppe’ ecosystem and see if it slows down – or even reverses – melting permafrost.
Massive landslides can trigger destructive and deadly tsunamis, and climate change could make them worse.
Peatlands will become a major source of greenhouse gases as the permafrost thaws.
Arctic heat waves were once rare and unusual events. But as their intensity and frequency increase with climate change, their fallout could affect the north — and the planet — for decades to come.
