Gaps in the global climate observing system make it harder to track progress, monitor adaptation & provide early warnings.
At #COP31 w/ @UNFCCC, we explored how coordination, protecting observations & closing gaps can secure the observations we depend on.

I never make a key climate intervention without consulting with a group of scientists first, to make sure my remarks are informed by the latest scientific evidence.
I thank the climate scientists who shared their insights with me today, ahead of tomorrow's #COP31 Leaders' Summit.

We've entered a new age of climate extremes:
A supersized El Niño is colliding with a planet already superheated by climate change.
The latest @WMO report shows once again that leaders must get serious by cutting emissions faster, accelerating a just transition from fossil fuels & delivering the finance & protection vulnerable countries need.

“The past 11 years have been the warmest on record and this trend is set to continue. CO2 has a very long lifetime and so will affect the global climate not just for years but for decades & even centuries,” @WMO Deputy Secretary-General Ko Barrett warned.

El Niño is back, and it is more powerful than ever.
We must act urgently to limit the impact.
With @WMO, we have set out the potential impact. And called for action.

When extreme weather hits, time is precious. AI could help forecasters move faster.
@WMO Secretary-General Celeste Saulo explains how AI is transforming weather forecasting, from analyzing massive amounts of data and running models faster to delivering early warnings in multiple languages.
