🔥 Ring of Fire Heat Dome will punch above its weight with near all-time records! The position of this heat dome / “ring of fire” (real term) will allow winds from the west on the north side of the dome to “downslope”/ flow downhills from the Appalachians & other mountains… 1/

This! Take a look at the dewpoint, which is the measure of moisture in the atmosphere. 60s = you can feel the thickness in the air 70s = tropical 79 in New Jersey is gross, pushing the feels like temperature 20 degrees higher! Note: this is not an official reading. #ItsAllAboutTheDewpoint

"Summers can be much rougher than the ones we and our parents and grandparents experienced. Every camp in the country should be ready for the seasons we actually have ‒ not the ones we used to have." www.usatoday.com/story/opinio... @4abrighterfuture.bsky.social

Incredible. 123 all-time records broken today in #France 2 sites had peak temps of 44°C/ 111°F

#Arctic sea ice in the Barents Sea is a record low for this time of year and potentially on its way to the earliest melt-out on record for the summer season. There is an area with sharply declining ice cover for long-term trends too. Map of the the region: zacklabe.com/arctic-clima...

🎙️ Great discussions need great moderators. Thanks to Paul Gross, Brigitte Perrin, Bernadette Woods Placky & Ariel Rodriguez for guiding the conversations at #FIMC2026. Connecting ideas, people & perspectives. @bernwoodsplacky.bsky.social @arielt51.bsky.social

You can even wear the stripes-they're a great convo starter!

ZOOMING OUT: Over 20 states woke up to exceptional, climate-driven near/all-time record warmth Thursday morning. 💡Did you know: Summer nights across the US are warming nearly TWICE AS FAST as summer days? On average, 231 U.S. major cities June-August nights have warmed by 3.1°

Breaking: El Niño is officially here, and it could break records. NOAA is giving it a 63% chance of becoming one of the “largest El Niño events in the historical record going back to 1950.” www.cnn.com/2026/06/11/w...

Despite attacks on climate science and the rise of disinformation, meaningful climate action continues to move forward. On June 16 at 2PM ET, I'm joining @globalecoguy.bsky.social, with @projectdrawdown.bsky.social, to talk about where climate action goes from here: us02web.zoom.us/webinar/regi...

Our oceans are extremely warm compared to the historical record. One of those areas of record high temperatures last month was across the North Pacific. Graph shows the average for a band across the midlatitudes for every May from 1854-2026 using NOAA ERSSTv5 data (psl.noaa.gov/data/gridded...). 🌊

So often, we think of climate change as a separate bucket at the end of the row of all of the buckets of things we care about. [But] climate change is the hole in every bucket. @climateactapp.bsky.social @katharinehayhoe.com climateactionnow.activehosted.com/index.php?ac...

Scientists are sounding the alarm about a new rule that would dramatically change how the federal gov't makes grant funding decisions. The rule is extraordinarily sweeping, and could have huge impacts on health and climate research. W/ @ellanilsen.bsky.social www.cnn.com/2026/06/04/c...

What an amazing duo!

Peak El Niño median forecast is now forecast ONI at +3.3°C (RONI +2.7°C) up .2°C from last month so far. If it verifies, it will be by far the strongest El Niño on record. Thanks @hausfath for the great visual.

It starts today! ALL are welcome.

#Hurricane season starts today. 🌊The Gulf of Mexico is running as one of the warmest on record for this time of year. El Niño will shape the season's forecast, but don't overlook this early-season ocean warmth -- particularly in the Gulf & Caribbean.

The Western European heatwave was so deviant for May it’s almost impossible to count all the records. Here’s a last 7-day review of all the records neared, tied, and broken. The pink are all-time May records! #heatwave #Europe

Yet again, another record-breaking heatwave is arriving well outside of the typical season. This time impacting the UK and other parts of western Europe with a strong ridge. 🥵 Here's how climate change is making that heat more likely via @climatecentral.org at csi.climatecentral.org/climate-shif...

Is climate change change making the European heat more likely? Yup! Deep red is at least 5X more likely.

Meeting up with the @wclivestream.bsky.social on their trek through Central NJ. There is a strong weather & climate science community here with @noaa.gov GFDL, C-Change Conversations, Watershed Institute, @princeton.edu, Climate Central. And of course, sporting my #stripes! @edhawkins.org

Western Europe Bakes! Pink dots are all-time records for May. I count at 30, but there are many more. Temps 15°C+ (almost 30F) above normal. For some areas a heatwave this extreme this early is without precedent, but climate change makes it much more likely, more intense and longer lasting.. 1/

NOAA's seasonal hurricane outlook for the Atlantic aggressively points to below normal activity given the growing confidence for a very powerful El Niño. It is crucially important to remember that climate change is supercharging tropical cyclones that DO form, with higher propensity for Cat 4 & 5.
