The world faces three existential threats: Runaway artificial intelligence. The climate crisis. And the intolerable deepening of inequalities. Next week, world leaders are coming together at #UNGA. My message to them: International cooperation is more important than ever.

Humanity is speeding towards a climate catastrophe. That’s the stark warning from the latest @UNEP report. Every fraction of a degree of warming will cost lives, deepen inequalities & push ecosystems closer to irreversible damage. We must raise ambition, accelerate #ClimateAction & fight for humanity.

As extreme heat is becoming more dangerous, we need more action to address it: 1. Protect people before heat becomes deadlier. 2. Make work safer. No one should have to risk their life to earn a living. 3. Build & retrofit for the heat. 4. Stop fuelling the crisis.

The climate fight will not be won in negotiating rooms, but through the actions we take in our communities. Local leaders have the responsibility to ensure the clean energy transition is fast, fair & delivers security, resilience & prosperity for all. They have my full support.

The clean energy future is already here. Renewables are the cheapest, fastest and most reliable source of new power. But the transition is still not fast & fair enough. This is our moment of choice, truth & opportunity to truly supercharge a global clean energy transition.

The climate crisis & the energy crisis may seem separate, but they share the same destructive origin: Fossil fuels. And they demand the same answer: A fast, fair transition to clean energy & a surge in adaptation, resilience & climate justice for those already facing climate harm.

For climate, this is the best of times & the worst of times. The worst – because climate impacts are intensifying & the energy crisis has exposed the deep risks of dependence on fossil fuels. The best – because the renewables revolution is well underway. We have the enormous opportunity – and responsibility - to turn this into a moment of resolve, fairness & shared progress. We can finally turn the page on fossil fuels & write a future powered by renewables & rooted in climate justice.

Methane drives around 1/3 of global warming and is 80 times more powerful than CO2. But aggressive cuts could deliver visible temperature benefits within a generation. That's why I’m launching a global call to cut methane emissions – in waste, agriculture & fossil fuels. This includes setting a new global standard for the oil & gas sector: near-zero methane emissions across the value chain.

The past eleven years have been the hottest on record. Every fraction of a degree brings greater harm – especially to the most vulnerable. This #WorldEnvironmentDay, warning signals are everywhere. This is the moment to act for our environment & for our future.

El Niño is arriving on our doorstep in the coming months with 90% certainty. The world must treat it as the urgent climate warning it is. The only effective response is #ClimateAction equal to the crisis – ending the addiction to fossil fuels, accelerating the shift to renewables, protecting the most vulnerable, and delivering early warning systems for all. wmo.int/resources/publicatio…
