How does a patch of warmer-than-normal water in the Pacific shift weather patterns thousands of kilometres away? This week’s new graphic and write-up explains how. www.climatetrunk.com/infographics... Visual #29 of 150 odd is on #ElNiño @climatetrunk.bsky.social @skepticalscience.bsky.social

El Niño reshuffles heat across the Pacific Ocean and into the atmosphere. This year’s Super El Niño is landing on top of a much hotter world, amplifying climate impacts already being felt.

Great to bring Climate Trunk to the Oxford World Forum hosted by the @smithschool.ox.ac.uk. Under the watchful eye of a fairly stern-looking former don, 20 Trunk visuals brightened up the wall a bit. @climatetrunk.bsky.social @oxfordnetzero.bsky.social @skepticalscience.bsky.social #WFSS

Why aviation’s climate impact flies above its emissions, and how we could bring it down. www.climatetrunk.com/infographics... Flying produces ~2.5% of global CO2 emissions, but closer to ~4% of heating. Visual 23 of 100+ 🌳 ✈️ @climatetrunk.bsky.social H/t @milank.bsky.social and others.

Aviation punches above the weight of its CO2 emissions.
Flying accounts for around 2.5% of global CO2 emissions, but closer to 4% of global heating once other effects are included. As other sectors of the economy decarbonise, aviation’s relative share of heating will rise.

Last week I asked if an historical version of @climatetrunk.bsky.social’s breakdown of annual emissions would be useful. The answer was an emphatic yes. Some familiar names loom much larger. @skepticalscience.bsky.social @visualisingclimate.com www.climatetrunk.com/infographics...

Just 35 companies can be linked to 40% of global CO2 emissions since 1854. CO2 emissions accumulate in the atmosphere over time. Today’s heating reflects the stock that has built up over generations – about 1.2 trillion tonnes.

John Lang @johnlang.bsky.social · 18/08/2026

Half of annual CO2 emissions can be traced to just 32 firms. Saudi Aramco is linked to 4% of the total, while China’s red giants dominate the picture. Squint and you'll spot the investor-owned firms we all know: Exxon, BP, Shell etc H/t @influencemap.bsky.social @climatetrunk.bsky.social 🌳

Just 32 companies were linked to more than half of global fossil-fuel and cement CO2 emissions in 2024. Emissions may be highly concentrated, but getting to net zero is a shared responsibility – fossil fuel producers are ultimately influenced by governments, companies, investors and individuals.

In 2018, climate scientist @drkatemarvel.bsky.social wrote in @sciam.bsky.social: 'Climate change isn't a cliff we fall off, but a slope we slide down.' The latest @climatetrunk.bsky.social visual and write-up explores that slope. www.climatetrunk.com/infographics... #12 of 100+ visuals

$Climate change is a slope we slide down, not a cliff we fall off. Every fraction of a degree matters: impacts worsen, risks compound, and avoiding additional heating reduces the risk of triggering dangerous, potentially irreversible tipping points.$

Climate change unfolds over decades. Political cycles don't. That's why countries are increasingly embedding climate action into law through targets, carbon budgets, independent oversight and long-term planning. This week's Climate Trunk graphic explores eight building blocks of effective climate governance.

Only 8 nations voted against the UN General Assembly backing the #ICJ’s landmark climate ruling. Combined, they account for one-third of historical CO2 emissions. The US (#1) + Russia (#3) make up the vast bulk, with generous support from Iran and Saudi Arabia. @daisydunne.carbonbrief.org

The UN General Assembly backed the ICJ’s landmark climate ruling by 141 votes to 8. The eight voting against, including the US and Russia, account for one-third of cumulative historical CO2 emissions since 1750.

This week’s @climatetrunk.bsky.social graphic shows how solar beat the IEA’s 2015 forecast for 2025 by 1,800%. The IEA expected the world to add about 34 GW of solar each year through to 2040. In 2025, the world added almost 650 GW. #9 of 100: www.climatetrunk.com/infographics... 🌞🌳

Solar is fast becoming the backbone of a new global electricity system. What once looked marginal is outgrowing expectations at breakneck speed – driven by plunging costs, learning curves and the explosive rise of batteries, which is turning daytime solar into anytime solar.

Climate and energy are hard to get your head around, unless you're in the climate Bluesky community. Over the last year, I’ve been building something to help everyone else: @climatetrunk.bsky.social 🌳 One visual a week, for a year. Probably two years now, given I've already drafted more than 52.

Most consequentially: Pre-Paris: world heading for ~4°C of heating by 2100. Post-Paris: down to ~2.6°C because of strengthened policy, #cleantech S-curves and #AmbitionLoops. (That is, assuming current policies are delivered and sustained.) @frediotto.bsky.social Credit: #WorldWeatherAttribution

John Lang @johnlang.bsky.social · 31/10/2025

Progress on reducing Amazon deforestation. Why? Because of renewed policy and enforcement. Brazil lost more rainforest than any other country in 2024 —due to to #wildfires — but the last few years show that better policy makes a massive difference. Now for #COP30 + #TropicalForestsForeverFacility

John Lang @johnlang.bsky.social · 31/10/2025

OK, not progress per se, but signs that climate risk really is becoming financially material, 10 years after Mark Carney's #TragedyOfTheHorizon speech. We zoom in on the #CanariesInTheCoalMine in the US. #InsurancePremiums @cathmckenna.bsky.social @marcdaalder.bsky.social

Clean energy #jobs (36.2m) now outnumber those in oil, gas and coal + ICE manufacturing (~33 million), and the gap is widening. #Renewablesjobs have nearly doubled from 8.5m in 2015 to 16.2m 2023. Updated @irena-official.bsky.social 2024 data dropping in December... 20m might be a stretch?

Climate policy has proliferated globally: - #ClimateFrameworkLaws have tripled since 2015. - Climate councils have also tripled. @climatecouncils.bsky.social - National climate policy tools are up seven-fold @oxfordnetzero.bsky.social @climatepolicyradar.bsky.social @granthamlse.bsky.social

83% of the 🌎 economy is still under #netzerotargets despite Trump's rollback of climate policy. 19 of the G20 are committed to #netzero by midcentury. 70% of the largest listed companies are still in, inc. most US firms. But yes, integrity's still crap. @netzerotracker.bsky.social @ketanjoshi.co

John Lang @johnlang.bsky.social · 31/10/2025

Global #CO2emissions plateaued: since 2015, annual emissions (including land use) are up by about 2%, compared with >18% in the decade before Paris. Since Paris, the annual CAGR increase in the growth rate of all #GHGemissions slowed to 0.32 %, a five-fold drop. @drsimevans.carbonbrief.org

#ElectricVehicles hit 20% of new car sales globally in 2024, and is on track for 40% by 2030, over 10 years ahead of the IEA’s 2015 forecast. @colin-walker.bsky.social gets troubled that PHEVs and BEVs are grouped together. Fair. But progress nonetheless. (I'll produce a solely BEV one next time.)

John Lang @johnlang.bsky.social · 31/10/2025

Investment in #cleanenergy now beats fossil fuels 2 to 1, with the gap wider in the Big Four: the US, EU, China and India. Like in the UK, China's #CleanEnergyEconomy is outpacing the wider economy threefold, now worth 10% of GDP. @eciu.net @davidrvetter.bsky.social

#Wind deployment kept pace. Added capacity in 2024: triple 2015 IEA forecasts. Wind's costs have edged up on average recently but both onshore and offshore still deliver electricity below the #fossilfuels average.

Couldn't resist reproducing the @ourworldindata.org graph of solar LCOE dropping off a cliff — yes a 2009 baseline (not 2015) because it tells such a compelling story. Since 2015, the #costcollapse was still a healthy 66%. @hannahritchie.bsky.social @chrisstark.bsky.social

#TheSunHasWon — solar beat IEA forecasts 1500% to became the 'cheapest electricity in history' 6 years after The Economist said it was uneconomic. In 2015, BP predicted the global non-fossil share of generation would rise from 32% to 38% by 2035. By 2024? >40% of power supply. @ember-energy.org

I often appreciate Daniel Yergin's dose of reality, but his claim that 'The 2050 target is enshrined in British law. But it is not embraced by others' is a dose of nonsense. - 100 countries have a #netzero target in law or policy - 130+ if we count 'Pledged' and 'Proposed' @eciu.net @ketanjoshi.co

John Lang @johnlang.bsky.social · 18/02/2025

The @netzerotracker.bsky.social now shows a drop from 93% to 78% thanks to Mr Trump's executive orders revoking mention of a federal-level #netzero target. Account for US states and that 78% becomes 84%. In total, 66% of the US economy *still* has deep reduction targets. My latest #infographic 👇
