🌍 What can we do as people to tackle climate change? Too often, the answer is framed narrowly around consumption choices. These choices are crucial for mitigation, but they’re only part of the story. We influence #climate change in many areas of our lives🧵

Because destroying the US is not enough, Trump is using tariffs, visa restrictions, and trade deals to pressure other countries to abandon climate goals and increase fossil fuel use, further destroying the world and the future.

As for that infamous Trump administration DOE "climate report" that Judith Curry recently co-authored, here are some assessments from the experts First, @sciencefeedback.bsky.social: science.feedback.org/review/misle...

#USpolitics #AGWdeniers @giacgrassi.bsky.social‬ e @caserinik.bsky.social fanno a polpette il rapporto dei 5 negaioli per il DOE. Sono stati più veloci del solito, ma gli argomenti di quei "mercanti di dubbi... sono già stati più volte confutati anche su Climalteranti."

"Nella mia regione X di rinnovabili ce ne sono già abbastanza" Quante volte avete sentito questo luogo comune? Nel post smonto questo mito per la Calabria, ma considerazioni simili valgono anche per altre regioni luigimoccia.substack.com/p/calabria-q...

Today on Volts: the sun doesn't shine at night, but if you add batteries it might as well! If you're not closely tracking the industry, you're probably not aware of just how cheap solar+storage is getting, and how quickly. I talk with the authors of a new Ember report about the good news.

#energiaeolica "Da qualche tempo, poi, alle solite complicazioni e lungaggini burocratiche si sono aggiunte proteste popolari che cominciano a mostrare aspetti inquietanti." Mi ricordano quelle in USA di cui parlava @amywestervelt.bsky.social 🔽

Un romanzo potente e disturbante sulla crisi climatica, che parla del nostro presente più di quanto vorremmo. Su Climalteranti il commento del professor Caserini su Diluvio: www.climalteranti.it/2025/07/02/d... @caserinik.bsky.social

Sicily is so hot that the region has just issued an ordinance to suspend various types of agricultural and construction activities on hot days to avoid accidents at work. Essentially these activities will be off at 12:30-16:00pm until 31/8. But let’s talk again how expensive climate mitigation is..

One of the biggest problems with the world is that fools are always so sure and certain about everything and intelligent people are so full of doubts and uncertainties.

NEW – Ocean current ‘collapse’ could trigger ‘profound cooling’ in northern Europe – even with global warming | @ceciliakeating.carbonbrief.org‬ w/comment from Rene van Westen Read here: buff.ly/iMXdkOR

#AGW @caserinik.bsky.social e altri ricercatori in scienze del clima e transizione energetica spiegano - brevemente - alla PdC Giorgia Meloni e al ministro G. Pichetto Fratin perché le emissioni di gas serra nei paesi UE vanno ridotte del 90% entro il 2040.

The political theory behind IRA was roughly as follows: We have lost control of the information landscape and can no longer win rhetorical or purely political battles; however, if we make substantive policy progress that directly touches voters' lives, they will notice and reward us.

www.nature.com/articles/s43... Warming of +1.5 °C is too high for polar ice sheets "Mass loss from ice sheets in Greenland and Antarctica has quadrupled since the 1990s and now represents the dominant source of global mean sea-level rise from the cryosphere."

📆Europe at a crossroads: the #GreenDeal in a trade war Today in Rome, we hosted a timely event on how Europe can respond to the US trade war. Discussions focused on shaping a united #European strategy that aligns with the Green Deal while ensuring strategic autonomy and industrial competitiveness.

Global average temperatures are spiking, rising faster than climate models seem able to explain, and in a sane world, every country would be united in a full-scale effort to figure this out & respond. Instead the US is dismantling its scientific infrastructure.

Denmark’s electric vehicle surge is just incredible. 🚗⚡️ Feb 2025: BEV 66.1%, PHEV 2.8%, ICE 31.1% Trailing 12M: 54.4% BEV ➡️ Only Norway ahead now, Sweden 3rd. ⛔️ ICE extinction event incoming? The internal combustion engine is pretty much over in Scandinavia. @leraffl.bsky.social

does Musk know what he's talking about, when he talks about climate? spoiler alert: no. youtu.be/IcnLcEGTikk

“Do you know of any challenge in the history of humankind that was successfully overcome that began with pessimism and defeatism? There isn’t. So optimism is a choice.” — Christiana Figueres, who knows what it looks like to tackle seemingly impossible challenge – and succeed!

Mary, if climate change is a sham, why did God create climate scientists who have definitively figured out that humans, not the sun, are causing climate change and how to stop it? See how that works?

Only a cruel God would create a human being with no brain

One of the most insidious arguments about renewable energy is that it is expensive because "it needs backup". This post from Electrotech Revolution explains in detail how adding renewable power to the grid *saves* money. open.substack.com/pub/electrot...

“We now expect a 3°C world,” Morgan Stanley analysts wrote earlier this month. They predicted this would be good for air conditioning stocks. Something it would not be good for? Life on Earth. www.eenews.net/articles/big...

Michel Barnard sta scrivendo una esaustiva serie di articoli divulgativi sul geotermico. Su questa fonte, di cui noi italiani siamo stati pionieri, c’è molta confusione. Di questa serie di post di Barnard consiglio di non perdere questo: cleantechnica.com/2025/03/21/c...

If someone says an entire field is “canceling” them, they’re most likely just a bullshit artist. Real scientists convince experts with evidence.

Hannah Ritchie is one of the few people who does the back-of-envelope calculations needed to provide context for numbers in the news. Doing such back-of-envelope calculations is a skill all of us should develop. www.sustainabilitybynumbers.com/p/whale-carb... @hannahritchie.bsky.social

Y’all wanna know what it really says in the Kennedy Papers? It says… … THE WORLD HAS WARMED BY 1.14°C SINCE KENNEDY’s ASSASSINATION THANKS MOSLTY TO THE COMBUSTION OF FOSSIL FUELS AND THE RATE OF WARMING IS ACCELERATING!!!

The new WMO State of the Climate report has a section by Gavin Schmidt and me on attributing exceptional 2023 and 2024 warmth. We find that while 2024 can be well explained by changes in forcings and internal variability, 2023 remains more of a mystery:

The people who produce this Mauna Loa atmospheric CO₂ record have a lab in Hilo, Hawaiʻi, about 50 miles (80 km) from the observatory. By closing the lab, it'll be really difficult to maintain the CO₂ observations.

The Criminal-Trump administration just revoked federal grants for EV charging stations across the US, aimed at promoting vehicles using fossil fuels. The only person who benefits from this is Elon Musk who has a Tesla network of charging stations, now available to other cars — for a fee.

Beautiful deal The free to read (tks!) paper explains how vast quantities of data show what lies under my old Nat. Geographic map 🔽. And why the Peninsula, Pine Island, Thwaites, most of W.A.'s glaciers & ice shelves loose mass while E.A.'s gain "modest amounts" - www.youtube.com/embed/6PLBEz....

Grazie @stefanocavok.bsky.social , fa piacere che le lezioni siano apprezzate.

It is about freedom of speach and fremdom of research in Europe. Europe must not join the spirit and action of intimidation currently prevailing in the USA.

The idea that the countries of the Global South will be capable of recycling materials that rich countries dump on them is unrealistic.
