We cannot air condition our way out of the heat crisis.
Many cooling methods add planet warming emissions, in-turn increasing cooling demand.

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.

More than 1,600 fossil fuel lobbyists have been granted access to the Cop30 climate negotiations in Belém, significantly outnumbering every single country’s delegation apart from the host Brazil, new analysis has found.
One in every 25 participants at this year’s UN climate summit is a fossil fuel lobbyist, according to the analysis by the Kick Big Polluters Out (KBPO) coalition, raising serious questions about the corporate capture and credibility of the annual Cop negotiations. Continue reading...

‘Change course now’: humanity has missed 1.5C climate target, says UN head
Exclusive: ‘Devastating consequences’ now inevitable but emissions cuts still vital, says António Guterres in sole interview before Cop30
*
I am the first Indigenous journalist to exclusively interview António 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, António Guterres acknowledged it is now “inevitable” that humanity will overshoot the target in the Paris climate agreement, with “devastating consequences” for the world.
This interview is also published in English, Portuguese and Spanish by Sumaúma. Continue reading...
