DC Climate Week starts Monday. 500 people in DC for the Opening Ceremony. Sold out. But you can watch live — globally, free — starting 1:30 PM ET. Come listen to @jigarshahdc.bsky.social, @ericwesoff.bsky.social, and more with @canarymedia.com streaming it worldwide. youtube.com/live/lmIe7UUtg6E

This seems suboptimal

"Clark et al. (2016) showed that decisions made in the next few decades will lock in sea level rise, ice sheet loss, and temperature change that persist for thousands of years — well beyond any planning horizon human civilization has ever contemplated."

Been living between a bunch of airbnbs the past month while my house is being repaired and after using induction for a decade, gas stoves suuuuuck. Gas stoves are so slow to boil water and heat up pans. Induction is hot magic.

* 2015-2025 was the hottest 11 years on record * Earth’s energy imbalance is the highest in 65-year record * The ocean has been absorbing about eighteen times the annual human energy use each year for the past two decades Probably fine.

The DC Climate Week 2026 Opening Ceremony is 50% sold out. Monday, April 20. Confirmed speakers include Jigar Shah, Katie Rae (Engine Ventures), Matthew Nordan (Azolla Ventures), Dave Turk, Nelson Switzer (Climate Innovation Capital), Eric Wesoff, and Victoria Herrmann. luma.com/2im2fa4b

DC Climate Week is back. April 20-26, Washington DC. Year 1: 4,731 people. 152 events. More hugs than handshakes. Year 2 is shaping up to be bigger. Full calendar: dcclimateweek.com

Rising sea levels are slowing Earth’s rotation, lengthening days by 1.33 milliseconds per century

Support my favorite podcast if you love hearing about how Climate-Tech is being deployed across the US and globally. David Roberts @volts.wtf is a hero that I constantly learn from. I was starstruck meeting him at NY Climate Week ‘25, thanks to a free ticket for subscribers ;).

Even as elites abandon any pretense of giving a shit ... climate change is accelerating.

Do you like charts? Oh yes you do. I've just published hundreds of them, as I do every year. www.nathanielbullard.com/presentations

Climate change is bad.

"Global investment in green technology for the first three quarters of the year has already surpassed all of 2024. The fortunes of the sector have been in decline for three years, but explosive energy demand fueled by data centers has sparked a reversal."

"Air pollution from oil and gas causes more than 90,000 premature deaths and sickens hundreds of thousands of people across the US each year, a new study shows..." If MAHA were anything other than dipshit reactionary fantasies & conspiracy theories, it would focus overwhelmingly on air pollution.

"a lot of people assume that there’s really great knowledge and huge due diligence on the chemical safety of these things. But it really isn’t the case.” We are swimming in a toxic soup of chemicals, + we know very little about what they're doing to us: www.theguardian.com/environment/...

In case anyone needs to reference the DOE's liftoff reports, which no longer appear on the official website: yardsale.energy/liftoff-repo... 🔌💡

DC Climate Week is heating up 📣 🔥 🎉 ! We have over 100 events on the public calendar and more than 2,000 people participating across the week! If you haven't checked the calendar lately, now is the time. Some extremely exciting events have been added! DCCW Calendar: lu.ma/dcclimateweek

DC Climate week is happening April 28 – May 2, 2025. Attendees will engage with policymakers, learn from world-renowned experts and help make the nation’s capital a sustainable model for other cities. Learn more here: ow.ly/IgZN50VAN9a #Partner

Last month was the 2nd warmest March on record for land areas around the world... Data provided by @noaa.gov NOAAGlobalTemp v6.0.0 (www.ncei.noaa.gov/products/lan...).

DC 1st Climate Week is April 28 to May 2! It’s going to be an amazing event with some exceptional speakers throughout the week. Now is the time for community members to organize their own events alongside the main programming. www.dcclimateweek.com

Update - my monthly climate change dashboard... Higher resolution graphic available at zacklabe.com/climate-chan...

Scientists think there's a decent chance that, if global temps rise 2 degrees above pre-industrial levels, it could trigger a cascade of tipping points that further accelerate warming, up to 5 or 6 degrees. AKA: "A cluster of abrupt shifts occur in ESMs [Earth system models] at 1.5 to 2ºC."

Just a quick head's up on the global f&%kery that's unfolding. In the middle of a La Nina, the global surface temperature anomaly year-to-date (Jan. 1 - Feb. 6) for 2025 is currently at 1.74°C above the 1850-1900 IPCC pre-industrial average. That's 1.74°C.

If DOGE really wants to save taxpayers money, they would deal with climate change because that shit’s gonna cost us trillions of dollars.

Say goodbye to the US as the best place in the world to be a scientist. 🧪

“One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss.” “Which means that Copenhagen, a city of 1.2 million people, saves $357 million a year on health costs because something like 80% of its population commutes by bike.” #CityMakingMath grist.org/biking/one-m...

My annual decarbonization presentation is here. 200 slides, covering everything from water levels in Lake Gatún to sulfur dioxide emissions to ESG fund flows to Chinese auto exports to artificial intelligence. www.nathanielbullard.com/presentations

A gentle reminder that if we miss the 1.5°C target (and we certainly will), the next target is 1.51°C and not 2°C. We need to keep fighting. Every tonne of CO₂ emitted makes the job of future CO₂ removal harder, and every 0.01°C of temperature increase makes the world more chaotic and dangerous.

When I was in graduate school, we were headed for 4-5°C of warming so this is progress. But it's not enough.
