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.

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.

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.

As for generation: almost 2,800 TWh in 2025, about as much electricity as the EU consumes in a year. That helped clean power meet all new electricity demand growth globally and nudged fossil generation into decline. h/t @ember-energy.org Solar’s going bananas and this is only the beginning ⚡🍌

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.

No country is too small to matter. Nations that each emit around 1% of global CO2 may look negligible on their own, but together they produce about 30% of the total – roughly as much as China. If they sit it out, the maths doesn’t stack up.

Climate change is bad news for societies built on stability. But the future is not pre-written. Within a single lifetime, the extent of heating – and the risks that come with it – depends on the choices societies make over the next decade or so.
