Yes, this week Lead Authors for the @ipcc.bsky.social Seventh Assessment Report (AR7) are meeting in Paris β€” almost 700 of us across all three working groups!

As IPCC Chair Jim Skea shares, there's even some highest-level climate diplomacy happening beyond the plenary sessions. πŸ‘‡

We cannot air condition our way out of the heat crisis.

Many cooling methods add planet warming emissions, in-turn increasing cooling demand.

But solutions exist to make cooling more sustainable & affordable: www.unep.org/news-and-sto...

When folks ask what I’ve done to reduce my personal carbon footprint, I say β€˜I moved from Toronto to Copenhagen’. It may sound glib, but per capita emissions are 3-4 lower. Our carbon footprints are shaped by our legislation.

The increasing participation of fossil-fuel lobbyists in recent COP meetings is concerning. Climate solutions should be shaped by those committed to real progress, not by those invested in slowing it down.

Hey Cryoverse! πŸ‘‹

If you need any motivation to call for action on the #AmbitionForMeltingIce at #COP30, check out the Glacier Casualty List. It's a global summary of 'critically endangered' & 'disappeared' glaciers and their stories.

It's really happening. πŸ§ŠπŸ’§

β€˜Change course now’: humanity has missed 1.5C climate target, says UN head Exclusive: β€˜Devastating consequences’ now inevitable but emissions cuts still vital, says AntΓ³nio Guterres in sole interview before Cop30 * I am the first Indigenous journalist to exclusively interview AntΓ³nio Guterres. How many others will listen? Humanity has failed to limit global heating to 1.5C and must change course immediately, the secretary general of the UN has warned. In his only interview before next month’s Cop30 climate summit, AntΓ³nio Guterres acknowledged it is now β€œinevitable” that humanity will overshoot the target in the Paris climate agreement, with β€œdevastating consequences” for the world. This interview is also published in English, Portuguese and Spanish by SumaΓΊma. Continue reading...
