New NOAA-led research reveals species in the Gulf of Mexico and South Atlantic that may be most vulnerable or more resilient to climate change, as well as the reasons why.

Short-term increases in fine particulate air pollution (PM2.5) during the summer and winter months in a mountain valley region of Utah were associated with increased health care visits for heart attack and unstable chest pain; however, the risk for each cardiac event differed by season, according to a preliminary study to be presented at the American Heart Association’s Scientific Sessions 2023. 

Up to now, the results of climate simulations have sometimes contradicted the analysis of climate traces from the past. 

Agriculture is one of the hardest human activities to decarbonize; people must eat, but the land-use practices associated with growing crops account for roughly a quarter of global greenhouse gas emissions. 

Methane ‘hot spots’ in the Yukon-Kuskokwim Delta are more likely to be found where recent wildfires burned into the tundra, altering carbon emissions from the land.

There are many creatures on our planet with more advanced senses than humans. 

UArizona researchers studied how young trees respond to a hotter, drier climate. 

Naturally occurring methane hydrate deposits are potential sources of energy. However, their observation in natural environments remains challenging.

Humans have raised the level of mercury in the atmosphere sevenfold, largely by burning coal, a new study finds.

The world’s largest dam removal and restoration project currently underway on the Klamath River in Oregon and California will aid salmon populations that have been devastated by disease and other factors.
