Why Polar Bears Approach Human Infrastructure? It's All About Ice
Findings suggest that sea ice loss probably doesn't lead to more interactions with people just because polar bears are thinner or hungrier.

Days Are Getting Slightly Longer As Earth's Spin Is Slowing At An "Unprecedented Rate"
Between 2000 and 2020, Earth's day length increased by 1.33 milliseconds per century due to climate-related mass redistribution.

Record-Breaking Drill Beneath Antarctic Ice Reveals Ancient Open Ocean and Future Sea Level Risks
Scientists drilled deeper than ever beneath the West Antarctic Ice Sheet and found sediment and marine remains showing the area was once open ocean. The 23-million-year record offers key clues about past melting, helping researchers better predict how quickly the ice sheet could retreat and affect future global sea levels.

NASA Spots Giant Antarctic Iceberg Turning Blue as It Nears Breakup
NASA scientists are closely tracking iceberg A-23A as vivid blue meltwater pools spread across its surface, signalling rapid decay. Once covering nearly 4,000 square kilometres, the Antarctic megaberg has shrunk to about 1,180 square kilometres and is fragmenting in warmer South Atlantic waters, offering valuable insight into how rising temperature...

New Study Explains Why Earth’s Poles Are Heating Up at an Alarming Rate
The Arctic is warming faster than anywhere on Earth, and new research reveals why. Using aircraft and ground measurements, scientists found that openings in sea ice boost cloud formation while pollution from oil fields alters Arctic chemistry. Together, these processes form powerful feedback loops that trap heat and speed ice loss. The findings hig...

Arctic Report Card Flags Fast Warming, Record Heat and New Risks
The 2025 Arctic Report Card shows the Arctic is warming faster than expected, with record heat, shrinking ice, stronger storms, and rusting rivers. Scientists warn that rising temperatures are reshaping ecosystems, threatening water safety, and increasing risks for Arctic communities. The changes highlight how quickly climate impacts are unfolding,...

Satellite Observations Record Arctic Sea Ice at Lowest Level of the Year
NASA satellites recorded Arctic sea ice at 1.78 million sq miles on Sept. 10, 2025—its tenth-lowest extent. Antarctic ice also stayed below seasonal averages. Scientists stress these lows reflect long-term climate-driven changes reshaping Earth’s polar regions.

Ariane 6 Launches Metop-SGA1 Weather Satellite into Polar Orbit
Europe’s heavy-lift Ariane 6 rocket completed its third successful launch on Aug. 12, 2025, lifting off from Kourou, French Guiana at 8:37 p.m. EDT. The mission carried Metop-SGA1, an 8,900-pound next-generation polar-orbiting weather satellite operated by EUMETSAT. Placed into an 800 km polar orbit 64 minutes after liftoff, Metop-SGA1 will deliv...

Greenland's Melting Glaciers Feed Ocean Life, Study Finds
A new NASA-led study reveals that Greenland’s melting glaciers are fueling life in the Arctic Ocean. Each summer, massive freshwater plumes from glaciers like Jakobshavn drag deep-sea nutrients upward, boosting phytoplankton growth by up to 40%. These microscopic organisms form the base of the marine food web and play a key role in carbon absorpt...

Greenland's Melting Ice Caps Reveal The True Extent Of Climate Change
In recent decades this territory 80 per cent of which is covered with ice has recorded a loss of frozen mass that outpaced previous estimates by 20 per cent.
