Global Warming

Record-high global temperatures aren’t driven only by well-known greenhouse gas culprits. These other emissions, unlike carbon dioxide, don’t have a direct warming effect on their own. Instead, they trigger reactions in the atmosphere that create more greenhouse gases or make the gases stick around longer. A new paper published Thursday…

Alaska’s glaciers are sending a stark climate signal, and Canada should pay close attention. In a new study based on synthetic aperture radar (SAR) observations, researchers found that each 1°C rise in average summer temperature extends glacier melt by roughly three weeks. They also showed that short, intense heatwaves can…

For decades, American politicians have been slow to take on climate change and curb carbon dioxide emissions, under the assumption that doing so might pass along costs to their voters. Ironically, their failure to rein in fossil fuel emissions has yielded the same result: Expenses for everyday Americans have soared…

So-called indirect greenhouse gases, including carbon monoxide and volatile organic compounds, aren’t covered by climate policies even though they heat the planet...Read More

Everyone knows the major chemical culprits responsible for climate change—carbon dioxide and methane—but there are a handful of lesser emissions that contribute, too. Now, in a policy paper published today in Science, leading scientists and climate experts are calling for these overlooked pollutants to be monitored and regulated as well. …

The upcoming loss of a deep-ocean monitoring system is triggering deep anxiety in Alaska, the nation’s top fish-producing state, where temperatures are warming twice as quickly as the global average. The National Science Foundation announced plans in May to decommission the Ocean Observatories Initiative, a nearly $368 million network of…

Global warming will amplify the impacts of El Niño events, and could also make them much stronger and more far-reaching...Read More

A group of the world’s leading climate scientists are warning governments and the livestock industry against adopting an “accounting trick” that will imperil the all-out global effort required to control heat-trapping emissions. In the statement, 42 scientists call on the government of Ireland, a major dairy producer, to reject a…

Scientists warn that heat stress could threaten vast numbers of insects in regions like the Amazon, potentially disrupting entire ecosystems. Tropical Insects…
