Fielding questions re: this article w/bizarre factual errors. First, there's no "Montecito County" in CA. Second, 2 fires are actually in *Monterey,* & 3rd in *Mendocino*. Third, 60k ac have *not* burned in either fictional Montecito nor real Mendocino.🤨 https://t.co/bl5tPxt2pH 24.8K views · 434 likes · 58 reposts · 33 replies Open on X →

If you missed it live, and are interested in this year's extreme El Niño event and its potential to bring major California impacts, I'd strongly encourage you to check out the recording! I even created some custom graphics just for this session... https://t.co/YG5ZnvHPps 25.1K views · 276 likes · 60 reposts · 9 replies Open on X →

I can now announce that, thanks to the support of the philanthropic funders behind the Climate Science and Communication Fund, the NSIDC Sea Ice Today blog has now returned (albeit in somewhat scaled back form)! https://t.co/QSlXnzWq9W 8.5K views · 124 likes · 14 reposts · 2 replies Open on X →

With widespread temperatures in 95-105F range, plus very high humidity (dew points mostly 65-70F), heat index/apparent temperatures are now 105-110F across most of SoCal, with pockets of 110-115F. Peak may be a bit higher still later this PM. This humid heatwave is no joke! #CAwx

Importantly, El Niño—even a very strong one—does not guarantee specific outcomes in California. However, this year’s exceptionally strong event will likely result in a strong tilt in the odds toward a wetter than average winter, and also toward individual heavy rain events. https
Screenshot of factsheet subsection text. It reads: "Importantly, El Niño—even a very strong one—does not guarantee specific outcomes in California. This is particularly true with respect to winter precipitation and inland flood risk. However, this year’s exceptionally strong event will likely result in a strong tilt in the odds toward a wetter than average winter, particularly in central and southern portions of the state, and also toward individual heavy precipitation events. This may increase the risk of inland freshwater flooding of rivers, creeks, and streams, though it is important to note that consequential flooding can occur in California during any winter—El Niño or otherwise."

While weak-moderate El Niño events exert modest/uncertain effects on California climate, very strong ones will likely cause: 1) Warmer near-shore ocean temperatures, 2) Higher sea levels and stronger wave action, & 3) Shifted winter storm track favoring increased seasonal precip
Screenshot of fact sheet subsection text. It begins: "What might this very strong El Niño event mean for California? While El Niño events of weak to moderate strength tend to exert only modest and/or uncertain effects on California climate, very strong east Pacific-based events (like this year’s) tend to increase confidence in larger and more widespread effects. These effects and potential consequences include: • Warmer near-shore ocean temperatures and higher coastal humidity; marine ecosystem disruption and potential for increased human health impacts from late summer/autumn heatwaves • Higher local sea levels and stronger wave action along coast, with elevated water levels in bays; risk of significant coastal inundation and/or erosion, especially during King Tides & storm events • A shifted winter storm track that favors increased seasonal precipitation; potential inland flood risk from heavy precipitation • Peak impacts arriving by November or December, and possibly lingering..."

Screenshot of fact sheet subsection text. It reads: "What might be the global effects of a very strong El Niño? Given its potentially historic magnitude, the current El Niño event will likely have substantial global impacts. By increasing the total amount of heat and water vapor in the Earth’s atmosphere, and by shifting global storm tracks, this event will likely contribute to significant regional drought and flood events, as well as extreme heat. Additionally, the temporary effects from this very strong El Niño event will amplify the effects of long-term warming from climate change, greatly elevating the likelihood of record-breaking global temperatures and extreme weather events during 2026-2027."

As of August, a strong El Niño event has already developed—and substantial further strengthening is expected. In fact, there's now very high likelihood (>90%) that El Niño will become very strong, and high likelihood (~70%) that the 2026 event will become the strongest on record.
Screenshot of fact sheet subsection text. It reads: "What is the forecast for 2026-2027? As of August 2026, a strong El Niño event has already developed in the tropical Pacific Ocean—and substantial further strengthening is expected. In fact, there is now a very high likelihood (>90%) that El Niño will become very strong, and a high likelihood (~70%) that the 2026 event will become the strongest on record (since at least 1950) later this year, likely peaking in intensity between October and December."

El Niño is the warm phase of a natural cycle (ENSO) occurring every 2-7 years in tropical Pacific Ocean. El Niño directly affects local climate in places closest to unusually warm ocean waters, but can also indirectly influence climate of distant regions thousands of miles away.
Screenshot of text from factsheet subsection. It reads: "What is El Niño? El Niño is the warm phase of a natural cycle, known as El Niño/Southern Oscillation (ENSO), that occurs roughly every 2-7 years in the tropical Pacific Ocean. During El Niño events, the eastern tropical Pacific Ocean warms to well above typical levels. El Niño directly affects local climate in the countries closest to the unusually warm ocean waters, but can also indirectly influence the climate of distant regions thousands of miles away. During the strongest events, El Niño can profoundly affect climate even on global scales, causing temporary planetary warming and disrupting large-scale precipitation patterns."

I've been talking a lot about the disastrous recent loss of American institutional capacity regarding climate science. But today, I'd like to announce something we've been working on, quietly, in the meantime to offer a lifeline to some of those affected. [Thread] https://t.co/Dh
