Data wants to be free. Lets help the @IEA free it! https://t.co/rftpvRArtI

Carbon removal is important, but how long it stays out of the atmosphere makes a big difference on resulting climate impacts. Here are the results of a simple climate model simulating a one-time removal of 10 GtCO2 in 2022, which is stored for 10, 20, 50, or 100+ years:

Interesting bipartisan action on climate adaptation, though I could do without the description of adaptation as "opposed to" mitigation. We can do (and need to do) both. https://t.co/tTpTWf3WDd

Good thread on the infinite silliness of folks claiming that scientists manufacture global warming by manipulating the temperature record. Extra points for the Buffy meme. https://t.co/elinO3uGDb

Many countries have adopted net-zero commitments later this century. In most cases these apply to all GHGs, not just CO2, and are structured using 100-year global warming potentials (GWP-100). It turns out this choice effectively commits countries to a lot of carbon removal. 1/

No @USDA, beef with a 10% lower carbon emissions is not "low carbon beef". Its still more carbon intensive than just about any other protein you could choose to eat: https://t.co/Z5P2hFyMqj

Our State of the Climate 2021 is out! https://t.co/gLkLUmt8tx ⬆ 5th or 6th highest surface temps ⬆ Warmest summer on land ⬆ Warmest year for 25 countries + 1.8 billion people ⬆ Record ocean heat ⬆ Record high GHGs ⬆ Record high sea levels ⬇ Record low glacier mass 1/18

Well, we tried our best, but in the end we got it. Symptoms are mostly mild for the family so far, thankfully. We had four negative at-home rapid antigen tests prior to positive PCR results, so treat those with a bit of caution.

The Tonga eruption yesterday appears to be one of the largest volcanic events we have seen in decades. We do not know how much cooling SO2 it has put in the stratosphere (data will come in later today), but this is the effect a Pinatubo-sized volcano would have on temps today:

Its understandable that everyone is dunking on this given sea level rise. But if there is anywhere the cost of massive sea walls and related infrastructure would not be prohibitive, its probably Manhattan. Also, large parts of many cities (SF, Boston, Miami) are built on infill. https://t.co/MBjtLO9TC1

Most observers think that current policies and commitments to reduce greenhouse emissions put us somewhere between the yellow and the light green, heading towards maybe 2.5 °C in 2100. That's a better path than we had a decade ago, but still not meeting Paris Agreement goals.

I have always thought that Primary Energy with substitution is a proxy for final energy. I am perhaps wrong... Substitution scales up non-fossil because of fossil efficiency. Final energy scales down fossil because of fossil efficiency. The problem. The level changes. 1/

As global warming continues, how often will a new year be the warmest yet observed? Looking at model simulations of the middle-of-the-road SSP2-4.5 scenario (about +3 °C in 2100), almost one year out of every 3 would set a new record. h/t @AndrewDessler for the idea.

A picture's worth a 1,000 words and it couldn't be any clearer: UK energy bills are skyrocketing because of very high wholesale gas prices https://t.co/V2wefGvdy7

We see this with all of the anti-science bad faith arguments. Regardless of how often people have pointed out how silly it is, or that it makes no logical sense, or that there would be no motive to doing something like that, the smugs will continue to make it.

Not gonna lie, best government website I have ever used. You just type your address, click one button, and they send some tests. Many said this could not be done, for some reason. And yet—behold! https://t.co/7ZMnlUxgap

The COP climate negotiations are the largest gatherings of world leaders in history. After 30 years of this process. Tonight's @EcoEye asks if we've made any ground in solving climate change and what does the future hold. Thanks @KevinClimate @hausfath for great contributions. https://t.co/wI3VQxERWO

Climate action, unlike deflecting a comet, won't bring immediate reward for politicians and companies. Even though results won't be seen for 20-30 years, we need to take action now. @laurent_bopp and I wrote about lessons from @GhostPanther's #DontLookUp. https://t.co/iKbLCXPAj9

Quick comparison of Berkeley Earth surface temperature measurements and the RSS and UAH satellite estimates of lower tropospheric temperature. Despite using the same observations, the two satellite data sets arrive at rather different estimates of recent warming.

First look at SO₂ in the Jan 15 #eruption cloud measured by @eumetsat MetOp/GOME-2. So far, the SO₂ columns do not appear to be extreme; generally <20 Dobson Units (DU). For a Pinatubo-scale event we'd expect SO₂ columns >100 DU. More data soon. Source: https://t.co/B7OcmWaX4Q

It is clear that massive eruption near Tonga produced an extremely large convection plume (on order of something generated by large nuclear detonation). It is *not* yet clear whether it actually emitted lots of SO2, which would be needed for it to have global climate effects. https://t.co/kar5VpfSyG

As people have noted in the replies this is from around 01:18 GMT (14:18 local time), prior to the bigger eruption at around 5pm local. Note that Aura has a local equatorial crossing time of 1:30pm. The next image will be revealing.

That plot shows a release of 62 kilotons of SO2. Mt. Pinatubo in 1991 released 20,000 kilotons; El Chicon of 1982, 7,000 tons. So the Tonga eruption needs to emit a lot more SO2 to reach the climate-cooling impact of those previous eruptions. See: https://t.co/FoRh2xBDWQ https://t.co/wrncTuuPMC

The Audubon Society, the Sierra Club, and other legacy environmentalist organizations are now engaging in NIMBY efforts to prevent the construction of solar and wind plants, thus endangering the fight against climate change. https://t.co/7Caj2OYNmW

Tonga's Hunga Tonga volcano just had one of the most violent volcano eruptions ever captured on satellite.
