2020 was Europe's hottest year on record as Arctic wildfires raged
Europe's average annual temperature in 2020 was the highest on record. Climate change also saw record-breaking wildfires in the Arctic.

This chart shows more than 30 years of Arctic sea ice cover
Data from the National Oceanic and Atmospheric Administration shows how Arctic sea ice cover in March - when it typically reaches its maximum - has changed.

Arctic sea ice winter peak in 2021 is joint-seventh lowest on record
Arctic sea ice has reached its maximum extent for the year. Here scientists explain what that means and put this year's figure in context.
SDG 13: Climate Action
Sea levels are rising fastest in big cities – here’s why
Jakarta, Shanghai and New Orleans are some of the cities worst affected by sea-level rises. These sinking cities need new solutions to safeguard their future.

Wind-blown dust is causing Greenland’s ice to melt faster
A study published in Nature Communications found phosphorus, a mineral in dust, is a key nutrient for an extensive glacier algae bloom on Greenland's ice sheet.
Climate Change
Polyester fibres are being found in areas as remote as the Arctic Ocean
Scientists have found evidence of tiny synthetic fibres which are consumed by sea creatures and could cause further damage to the fragile Arctic ecosystem.
Climate Indicators
Here's how sea ice algae could show past and future climate change
As sea ice concentration ebbs and flows, so do the algae associated with it, as well as the molecules they leave behind, which can help scientists determine past temperatures.

Where’s the sea ice? 3 reasons the Arctic freeze is unseasonably late and why it matters
Global warming, highlighted by the Siberian heatwave in June, has meant that much of the Arctic's sea ice hasn't formed. This can cause a cycle of more melting sea ice.

Arctic Ocean: why winter sea ice has stalled, and what it means for the rest of the world
Multi-year ice helps reflect the sun's rays, reducing the rate of global warming. However, these ice sheets are rapidly disappearing, releasing CO2 and raising sea levels.

Zombie fires and other strange events are happening in the Arctic – here’s what you need to know
Warming temperatures could be creating underground wildfires, while explosive craters appear in the Siberian tundra.

Arctic sea ice shrinks to second-lowest 'summer minimum' on record
This year, the Arctic sea ice has reached its second lowest 'summer minimum' on record, according to data from the National Snow and Ice Data Center (NSIDC).

Arctic sea ice shrinks to second-lowest 'summer minimum' on record
This year, the Arctic sea ice has reached its second lowest 'summer minimum' on record, according to data from the National Snow and Ice Data Center (NSIDC).

Scientists have figured out just how cold the last Ice Age was. Here's why it matters
The global average temperature, during the period known as the last glacial maximum, is thought to be around 46 degrees Fahrenheit (7.8 degrees Celsius).
Antarctica
Antarctica's giant ice shelves are vulnerable to collapse, study warns
A recent study has found that about 60% of the ice shelf area is vulnerable to a process call hydrofracturing, where meltwater seeps into the shelves’ crevasses and triggers collapse.

Global warming: Scientists 'stunned' by how much ice we've lost
The rise in temperature across the Arctic Ocean between Canada, Russia, and Europe is faster than climate models have previously predicted.
