Climate Change, Heat, and Death (Part 2)


Following yesterday’s blog post on the human health (and death) implications of sustained, high heat, new maps and projections from the Climate Impact Lab ( illustrate the increase in the number of 95 F (35 C) days that we can expect to see given climate change. Even under relatively modest reductions in global emissions (based on the Paris Accord), the number of extreme heat days (those 95 F or greater) are expected to grow by the end of the century.  The hardest hit areas are those near the equator. If there are no changes to emissions and no action is taken on global warming, the situation is even worse, with some equatorial locations experiencing these extreme heat days most of the year.

Of course, such heat events will have impacts on mortality, as my previous blog discussed. But the impact of extreme extends further, and includes lower crop yields – a real problem when the world is asked to feed a growing population! Yet additional reasons for why we must tackle climate change.
