The 2024 Hajj heatwave hit 51.8 °C, killing 1,300+ people. New research shows such extremes are becoming the new normal with climate change—and could happen annually later this century. Adaptation is now lifesaving.

We are now tracking 69 projects, $70.5B in investment, and 66,758 jobs that have been delayed, shrunk, paused, or cancelled since Trump took office.

And if solar parks are built near villages or towns, then offer the people who are potentially affected free electricity to offset their concerns.
Solar panels are not nuclear power stations. They can be removed with little environmental impact and can actually benefit biodiversity.

The solution is right above us. Solar panels on existing buildings, car parks, and along highways generate clean power without sacrificing farmland or wild spaces. Let's use our built world first. #Renewables #Innovation

Conditional on a moderately strong El Nino, I estimate that 2027 will likely be around 1.6C above preindustrial levels, though the uncertainties are huge and range from as low as 1.3C (with no El Nino) to as high as 1.8C (with an exceptionally strong one).

It appears increasingly likely that an El Nino event will develop in the latter half of 2026, which will contribute to higher global temperatures in 2027 (on top of long-term warming). However, it still remains highly uncertain how it will develop.
