Higher-resolution models don’t consistently improve accuracy of extreme rainfall predictions, a new study finds. A better approach may balance model resolution and model intricacies.

A new study compared wind data alongside Sargassum Inundation Risk (SIR) maps against citizen science reports from the coasts of Florida, Gulf of Mexico, Bahamas, and Caribbean regions. The study found that including shoreward wind velocity greatly improves the agreement with coastal observations of Sargassum beaching compared to SIR indicators alone.
New research confirms that, even as the Arctic warms faster than the rest of the world, cold-air outbreaks from the polar region will continue across the Northern Hemisphere in the coming decades.
Around the world, from the surface waters to the seafloor, our oceans are warming, and we are beginning to adapt to and prepare for this change in our climate.
Carbon dioxide levels also recorded a big jump.
For the second year in a row, NOAA scientists observed a record annual increase in atmospheric levels of methane, a powerful, heat-trapping greenhouse gas that’s the second biggest contributor to human-caused global warming after carbon dioxide.
Days with the most prominent Saharan dust correlated with fewer thunderstorms in the Atlantic and less rainfall across Puerto Rico, a pattern that has become more frequent over the past 40 years.
Key Findings According to GFDL ESM4.1, burned area and fire carbon emissions have increased since the 1950s in Alaska, especially in July, resulting in more frequent extreme events as in 2019. The…
A new climate model simulates realistic extreme precipitation over the Northeastern United States. By the mid-twenty-first century, the model projects unprecedented rainfall events over the region under the IPCC’s SSP5-8.5 scenario. Extreme precipitation (top 1 percent of daily precipitation) would double its frequency by the end of the century.
Key Findings Global warming made the 2018 Cape Town “Day Zero” drought five-to-six times more likely than it would have been in the 19th century, based on results from a new high…
