Global warming is caused by humanity’s greenhouse gas emissions, which continue at near-record pace.

Our world-first analysis, published today, examines the experience of global warming over the lifetimes of people around the world: young and old, rich and poor.

First, we wanted to know, for every location in the world, how clearly global warming could be perceived, relative to natural temperature variability.

We might conclude people in the poorest parts of the world have experienced the most perceptible global warming over their lifetimes.

In these places, the lack of recent warming is likely down to a few factors: natural climate variability, and the local cooling effect of particles released into the atmosphere from pollution and changes in land use.

Identifying who has experienced significant global warming in their lives may help explain attitudes to tackling climate change.

Of course, warming temperatures are not the only way people experience climate change.
