Arctic sea ice decline has resumed with a record winter reduction between 2024-2025, ending a previously observed slowdown. Researchers attribute the temporary reprieve to natural ocean variations, warning of ongoing climate crisis impacts.
Researchers in Cambridge Bay, Canada, experimented with spraying seawater onto existing sea ice to thicken it. The treated ice grew significantly thicker and remained more reflective, showing promise for combating Arctic sea ice melt, though large-scale application faces significant challenges.
New research suggests Antarctica's sea ice loss, linked to cloud cover and ocean heat absorption, could accelerate global warming faster than previously thought. Recent record-low sea ice extents and higher regional temperatures signal a major climate shift, with potential for amplified warming and more severe climate impacts globally.
New research suggests Antarctica's sea ice and cloud cover have a stronger link to global warming than previously believed. The study by the European Geosciences Union (EGU) indicates potential underestimation of ocean heat absorption and climate sensitivity in current models, raising concerns about faster and more severe future warming.
A UK-funded geoengineering experiment in Cambridge Bay, Canada, is pumping ocean water onto sea ice to thicken it and combat rapid melting due to climate change. The "Real Ice" project aims to test the feasibility and safety of refreezing Arctic ice, with potential benefits for local communities and global climate.
