The deluge capped a summer of extreme climate events, from deadly heatwaves to wildfires. We must take action now

For millennia, the high peaks of the Himalayas were held together by an invisible, frozen cement – permafrost and glacial ice that bound ancient rock into seemingly unshakable fortresses. But as the planet continues to warm, this alpine glue is liquefying.

The glacial collapse and deluge in Nepal and Tibet was not a freak weather event; it was the structural failure of a mountain itself, nature’s latest commentary on the deadly consequences of human-caused planetary warming. And it was the exclamation point on a summer of extremes, illustrating with a sole unnatural disaster the apocalyptic future that lies in store if we fail to take dramatic climate action.

Richer countries might have more resources to deal with catastrophe, but this problem grips the entire planet, however much leaders may want to deny it

Climate breakdown is happening on one Earth, but two different worlds. In one, its impacts increasingly encroach on everyday life; longer periods of discomfort and shorter periods of sharp pain. Endless, hotter summers, and within them sudden wildfires, evacuations, homes burned to cinders in a matter of hours. In another, catastrophe. This summer has been a snapshot of that split-screen. The hottest day on record in parts of Europe, and a wave of water, mud and ice in Nepal that so far has claimed more than 750 lives. Thousands of people are still missing.

The difference is also one of resources. The climate crisis has an economic cost, but some places can absorb it better than others. Responses to this summer of wildfires in Europe included a rapid scrambling by the French government to provide everything from tax breaks for businesses affected by the fires to relocation costs and aid to rebuild homes. The UK government had deployed almost £100m before the summer to strengthen wildfire resilience.
