My @TEDCountdown talk is live. Thank you @chrishemsworth and @priyankachopra for the wonderful introduction. It was a rare and unexpected honour to come on stage after Pope Francis with his important message on equality, love and environment @Pontifex

Meet me in Dublin the 19th of November:

Good post on cherry picked non-science graphs people are floating.

Only 3 in 10 Veterans know about 0% down home loans. Join our mission to help veterans find their way home.

The atmospheric CO₂ growth rate was off the chart in 2024!

Deniers say ‘CO2 is plant food - so it can’t cause climate change’. That’s like saying water is essential to life - so it’s impossible to drown.

The Lomborg trolley problem: Save the climate OR help the poor. The most likely option is to do neither. Climate sceptics are increasingly anti vaxx. We are in the era of the destruction of USAID AND climate goals.

The "only way" says this childish post with ice in a glass- while thermal expansion has been a significant contributor to sea level rise in recent decades.

Iceland Noir is becoming one of the best literary festivals I have attended. Doing an early warmup today in Fríkirkjan for some great authors, legendary George R.R Martin closing the festival.

Never forget: At breakneck speed we are leaving the stable Holocene climate in which human society developed and thrived. Weather extremes are outside historical experience. Sea-level rise is accelerating. Dangerous tipping points are ahead. Graph: https://t.co/UNaqGEKMQc

@volcaholic1 I know vollie firefighters here in Australia and one of them once said to me: "You won't see a climate change denier at the end of a fire hose."

Imagine a world so filled with magic that it seems normal. You can fly through the air, project yourself into crystal balls across the globe, remove heat from buildings, see through transparent walls… The magic is so common that the magicians — the people who learned the arcane

The end of the internal combustion engine? Sales of petrol and diesel cars in China peaked in 2017 and are now falling rapidly. The shift to electric and low-carbon transport is well underway—and EV sales are rising fast.

Heat pumps are magical machines. Instead of combusting fossil fuels to generate heat they transport heat from the air, ground or water into your home. This reduces carbon emissions instantly by about 80% with the current electricity mix. It will be close to 100% by mid 2030s

Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004. Today, building a fence with solar can be cheaper than using wood.

The 4 Horsemen of Climate Reality I just spent the last 2 days at the Sustainable Ocean Solutions conference in SF and it revealed the harsh realities of how much work is needed to respond to Climate Change. Unfortunately, most of the problems aren't scientific. 1. Noise. In

Battery costs = 📉 Battery storage capacity = 📈 69 GW of capacity was installed in 2024, nearly DOUBLING total battery storage capacity 🔋 https://t.co/dEcMEGCY1v

More grim news, whichever way you look at it But no surprise https://t.co/hpOf9MP00V

What does one of the richest men in the world get wrong about climate change? Ahead of this month’s COP30 summit in Brazil, Bill Gates is advising world leaders that global warming “will not lead to humanity’s demise.” But is that true? Join me and fellow scientists
