New paper in @theAGU GRL. A simple non-Gaussian extension of linear climate models that reproduces key observed ENSO features: diversity, asymmetry, and extremes, including the curved El Niño–La Niña phase space and the dominance of extreme El Niño events https://t.co/7fgzlfJvyt

I’m a climate scientist. Let me fix this headline.

“Nearly a century ago, scientists showed that burning fossil fuels warms the planet.*

Today, we know human emissions account for over 100% of the warming.**

Yet dark money and disinformation still work to keep Americans addicted to fossil fuels.”***

* in 1937, Guy Callendar published a paper showing that the world had already warmed over the last 50 years due to human emissions what he called “carbonic acid“ – what we now call CO2 – from burning fossil fuels

** If you are wondering, “how could humans be causing more than 100% of the warming?”

— it’s because, according to natural factors, the earth should be cooling right now.

So our emissions are offsetting that cooling AND causing all of the observed warming.

Big El Niño? The window is closing. June’s westerly wind bursts may decide everything.

Yes, the ocean looks a lot like early 1997: warm water expanding east across the equatorial Pacific, Kelvin wave warming lighting up the South American coast.

But El Niño is an ocean-atmosphere phenomenon. And the atmosphere is not cooperating.

By late May 1997, a major westerly wind burst was already ripping across the western Pacific, helping tip the system into the strongest El Niño on record.

This year? Nothing of the sort. No sustained WWB so far. If anything, the opposite — a possibility some 2-week weather forecasts were already flagging when NOAA issued NOAA’s May outlook.

That doesn’t mean a big El Niño is off the table. It means caution is still warranted when using 1997 as an analog, because the next few weeks matter a lot.

Surface maps can look similar. Forecast outcomes can still diverge sharply.

This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.

Anthropogenic aerosol forcing is perceived as highly uncertain. Our new paper shows that the uncertainty is in the magnitude while the spatial pattern of the climate response is robust across models.

Big El Niños 🌊 usually have big 🌎 teleconnections.
The one in 2023/24 didn’t. Why?
Rainfall anomalies in the tropical Pacific were suppressed due to greater warming in Indian and Atlantic Oceans.
