The World Meteorological Organization (WMO) has issued a “red alert” as all major global climate records — greenhouse gas levels, near-surface temperatures, ocean heat and acidification, Antarctic sea ice cover, glacier retreat and sea level rise — were broken in 2023, a WMO press release said. Floods, swiftly intensifying tropical cyclones, heat waves, drought and […]
If you thought this year was exceptionally hot, you were right. Not only has it been the warmest year on record, it’s on track to be the warmest the planet has been in a quarter of a million years. Scientists at the Copernicus Climate Change Service (C3S) say 2023 is almost certain to be the […]
Recent satellite data from the U.S. National Snow and Ice Data Center shows that Antarctic sea ice extent is far below any level ever recorded. The continent’s sea ice is an important regulator of Earth’s temperature by not only lowering the temperature of the water below, but also reflecting the sun’s rays back into the […]
A new study has found a direct link between human-caused greenhouse gas emissions and the survival of polar bear cubs. The findings could help address a former legal opinion that impacts polar bear protections. A 2008 legal opinion from the Solicitor of the Department of Interior noted that emissions did not need to be considered […]
Rapid global heating due to humans’ use of fossil fuels has contributed to an array of damaging environmental effects on the planet, including extreme weather, unprecedented ocean temperatures and a rapid decline in sea ice. Sea ice is the habitat of several animal species, including polar bears, Arctic fox, caribou and emperor penguins, who live […]
Quick Key Facts What Is Arctic Sea Ice? Sea ice forms and covers most of the Arctic Ocean during the shorter, darker winter months. How much of the ocean’s surface is covered in sea ice is an important indicator of climate change. By mid-September, after the summer melt, the area covered by Arctic sea ice […]
Even with dramatic shifts in emissions, summer sea ice in the Arctic is doomed. A new analysis has found that even greatly and swiftly reducing greenhouse gas emissions will not prevent the disappearance of sea ice in September over the coming decades. Researchers predict the first summer without Arctic sea ice will happen in the […]
Evidence from the last ice age has troubling implications for future sea level rise. The research, published in Nature Wednesday, found that ice sheets could collapse around 20 times faster than previously assumed as the climate warms. “Our research provides a warning from the past about the speeds that ice sheets are physically capable of […]
The Arctic sea ice extent for the Northern Hemisphere winter of 2023 is the fifth lowest on record. The National Snow and Ice Data Center (NSIDC) announced Wednesday that the Arctic sea ice likely reached its maximum extent on March 6 at 5.64 million square miles. That’s 398,000 square miles below the average maximum for […]
