New Study Finds That the Gulf Stream is Warming and Shifting Closer to Shore
The Gulf Stream is intrinsic to the global climate system, bringing warm waters from the Caribbean up the East Coast of the United States. As it flows along the coast and then across the Atlantic Ocean, this powerful ocean current influences weather patterns and storms, and it carries heat from the tropics to higher latitudes as part of the Atlantic Meridional Overturning Circulation.
A new study published today in Nature Climate Change now documents that over the past 20 years, the Gulf Stream has warmed faster than the global ocean as a whole and has shifted towards the coast. The study, led by Robert Todd, a physical oceanographer at the Woods Hole Oceanographic Institution (WHOI), relies on over 25,000 temperature and salinity profiles collected between 2001 and 2023.

FSU atmospheric scientist available to comment on what El Niño conditions mean for winter, spring
By: Patty Cox | Published: October 2, 2023 | 12:30 pm | SHARE: El Niño, the climate phenomenon characterized by warmer-than-average sea surface temperatures across the equatorial central and eastern Pacific Ocean, has far-reaching impacts on weather patterns across the globe. El Niño events can last for several months up to a year or more and typically peak in the winter months of the Northern Hemisphere, so we’re likely to see El Niño conditions continue to strengthen over the coming months, said Alyssa Atwood, an assistant professor in Florida State University’s Department of Earth, Ocean and Atmospheric Science, part of the College of Arts and Sciences.
Important additional driver of insect decline identified: Weather explains the decline and rise of insect biomass over 34 years

Researchers investigated how large-scale urbanization and irrigation in the United States affect the three dominant types of summer precipitation in the mid-Atlantic region. They found that urbanization suppresses all three types of precipitation. Irrigation enhances non-convective and isolated deep convection precipitation, and its effects on mesoscale convective systems (MCS) depends on whether an MCS formed locally or remotely.
