The Arctic is the "frontline" for climate change, scientists said. If there is any doubt about climate change, look no further than the coldest regions of the planet for proof that the planet is ...

The Arctic Ocean, once locked in a vault of thick, old ice, now is transforming at lightspeed. Temperatures there are increasing at up to four times the rate of the planet overall, melting sea ice ...

Arctic sea ice is melting at an accelerated rate, leading to a warmer ocean that absorbs more sunlight. This loss of ice disrupts the polar vortex, potentially causing colder Arctic air to spill south ...

Melting Arctic ice is revealing a hidden world of nitrogen-fixing bacteria beneath the surface. These microbes, not the usual cyanobacteria, enrich the ocean with nitrogen, fueling algae growth that ...

Arctic Passages: Ice, Exploration and the Battle for Power at the Top of the World. By Kieran Mulvaney. Island Press; 240 pages; $30 and £24 Ends of the Earth: Journeys to the Polar Regions in Search ...

The Arctic region is undergoing significant environmental changes due to the rapid melting of sea ice, with researchers increasingly focused on the potential ecological shifts that accompany it.

In a nutshell: Although global temperatures continue to rise, Arctic sea ice hasn't declined as quickly as models predicted. Scientists warn that this temporary slowdown likely won't change the ...

As the Arctic Ocean loses its sea ice due to climate change, sunlight penetrates deeper into the water and encourages the growth of tiny plant-like organisms (phytoplankton). But to thrive, they need ...
