Ocean scientists are one step closer to understanding the connection between warming in the Eastern Tropical Pacific Ocean and its impact on weather and climate. The new study by @oceanclilmatecu.bsky.social and partners in @agu.org Earth's Future is spotlighted here! buff.ly/Tcbj2fq

Today, we published a study long in the making on how upper and subsurface tropical Pacific waters responded (and maybe will adjust) to warmer global climate. Here’s the story of how we got here after 15 years. many authors but shout out @jfarmersalmanac.bsky.social

Persistent eastern equatorial Pacific Ocean upwelling since the warm Pliocene

Upwelling generates a nutrient-rich “cold tongue” in the eastern equatorial Pacific Ocean (EEP), with impacts on global climate, oceanic biological productivity, and the carbon cycle. The cold tongue ...

"my mentee sent an email thanking me for my support and guidance, which she said helped increase her confidence. She probably doesn’t know that she helped increase my confidence, too."

As a Ph.D. student, I felt unprepared to mentor—but I’m glad I took the leap

“I could help even when I did not have a solution,” this scientist learned

The one in 2023/24 didn't. Why?

Our general tendency to underestimate equatorial upwelling may offer a clue into the disagreement between historical trends and climate model simulations of Pacific SSTs.

Climate.gov, a major US government website supporting public education on climate science, will likely shut down after almost all of its staff were fired. What would be worse is if the website were co-opted to publish climate denial content.

185 departures in a day. Up about 50% from this time in 2021. (Nothing to do with the holiday weekend. Last Thursday was just an average day in terms of traffic.)
