Climate finance isn’t charity, it’s an investment in global stability and a livable planet.
From funding clean energy to drought-resilient seeds for farmers, it cuts emissions and strengthens communities.

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.

🌍 Happy #InternationalYouthDay!

Young people aren’t waiting for change — they’re making it happen.

For #IYD2026, ASG @felipepaullier calls for investment in future-ready skills, meaningful youth participation and every young person’s potential.

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.

[UN Climate Change @UNFCCC]

“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.

[Annalena Baerbock @UN_PGA]

“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

[Simon Stiell @simonstiell]

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.

Annual renewable capacity additions have increased notably over the past 25 years, reaching an unprecedented peak of 693 GW in 2025. This positive trend in installed capacity confirms that renewable deployment continues to outpace fossil-fuel growth.

Sand and dust storms are natural phenomena, but they are growing increasingly frequent and severe.

Climate change is already affecting our lives... and ⚽️ is no exception.

14 of 16 #WorldCup2026 host stadiums already face multiple major climate hazards, including extreme heat, heavy rainfall and flooding.

The good news? The solutions already exist 👇

[Simon Stiell @simonstiell]

US cities hosting #WorldCup matches are twice as likely to see extreme heat & storms than in 1994, and we’re seeing that play out.

That’s climate change - driven by burning massive amounts of coal, oil and gas.

The solutions already exist: clean energy and building resilience.

[Int’l Telecommunication Union @ITU]

Across all stages of the #EarlyWarnings value cycle, AI is reshaping how we protect lives.

New @ITU report shows how AI can strengthen early warning systems through strong infrastructure, partnerships, and a human-centered, responsible approach.

The annual #SDGReport makes two things unmistakably clear: the Sustainable Development Goals work. They are delivering for people — but not fast enough, not evenly and not without setbacks.

They are still within reach, but only if we act with greater urgency, solidarity and political will.

The next four years are our opportunity to accelerate progress and deliver on the promise of the SDGs.

Ocean waters in the South-West Pacific are becoming hotter and more acidic, harming economies & marine ecosystems. Sea level rise is threatening coastal communities & low-lying island nations.

New @IRENA report: Over 90% of the utility-scale renewable capacity added in 2025 was cheaper than the lowest-cost new fossil alternative.

In total, installed renewables helped avoid an estimated USD 480 billion in fossil-fuel costs in 2025.

[Simon Stiell @simonstiell]

Europe’s savage heatwave has the fingerprints of the climate crisis all over it.

Until humanity stops burning coal, oil and gas, extreme heat will keep getting worse.

The solutions are clear: a faster shift to renewables, protecting forests and boosting climate resilience.

[UN Climate Change @UNFCCC]

From local pitches to the World Cup, football brings people together

But climate change is reshaping the conditions the game is played in

The shift to clean energy and stronger resilience is already underway. Now we must move faster to protect the game & everyone who watches it
