Dear reader,

In many parts of the world, this has been another summer of devastating, extreme heat – having a catastrophic impact on the planet and all that lives on it.

Throughout the summer months, my team of environment reporters have been sending dispatches from across the world on how extreme heat impacts everyone and everything, in every corner of the globe: from burning wetlands in the Amazon to agricultural workers picking food in unbearable heat in rich northern-hemisphere countries to wildfires in California, Canada and beyond.

Alongside this reporting, the Guardian has been encouraging regular readers like you to sign up to financially support our journalism.

We’re committed to covering the dangers of the climate emergency – as well as exposing its causes, and providing ideas and alternatives for those in positions to effect global, systemic change.

We won’t stop as the summer heat fades. But we need your help to keep going.

If you can afford it, please consider backing our journalism with a one-off payment or from just £4 per month. It takes less than a minute to sign up, and makes all the difference in the world.

Thank you
Natalie Hanman
Head of environment,
The Guardian
