New @IRENA data: global renewables avoided almost half a trillion US$ in fossil fuel costs. With fossil fuel dependency driving higher food prices & inflation, any leader must be serious about cutting planet-baking fossil fuels & building resilience. bit.ly/4cV5TtE

Climate is sometimes seen as territory in the culture wars. It's not. Climate impacts like extreme heat are killing thousands, driving up costs, hitting economies and energy security. Inflation is a common enemy, security is a common cause. Both demand action on climate.

Today, the world meets for #COP17Mongolia. Droughts have increased by nearly 30% since 2000. But restoring 150 million hectares of degraded land, an area the size of our host, Mongolia, could provide food for 200 million people. unccd.int/cop17 #UNited4Land @UNCCD

Created at COP22, the Marrakech Partnership turns ten this year. As we prepare for COP31 in Antalya, it's more relevant than ever. It's the platform connecting governments with businesses, cities, investors and civil society to turn Paris Agreement goals into action: tripling renewables, halting deforestation, building climate-resilient health systems, and more. Today it brings together initiatives under the Global Climate Action Agenda, working through “Plans to Accelerate Solutions” to unblock what's stopping climate solutions from scaling.

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 verdict is clear: the climate crisis is in overdrive.” – @antonioguterres on the new global climate forecast released today by the @WMO. More coal, oil and gas will lead to a more combustible future. Unless we act – to protect people and tackle the root cause of the crisis.

“The answers are all there. But the matching is missing.” Today I convened an Interactive Dialogue on the Global Energy Transition. UNFCCC’s @simonstiell was direct: finance is essential to building resilience. IRENA’s @flacamera put it simply: geology no longer decides who has power. And ASG @SelwinHart reminded us that this revolution is “unstoppable and irreversible. Now we need to deliver, for everyone, including Africa. #UNGA80

A world addicted to coal, oil & gas is a world of instability and rising costs for all. Renewables are cheaper, safer and faster to market. They can fortify the foundations of peace – while cutting planet-heating pollution and supercharging economies. 👉 bit.ly/4x1qVhY
