The South Pole is warming, and warming fast. In the last 30 years, the place furthest from the summer sun, the place where one winter’s night lasts for 179 days, has been warming at 0.6°C per decade. This is three times the speed of average warming for the whole planet. The finding is unexpected. The geographic South Pole is not only the most extreme location in the southern hemisphere, it is also at Alpine altitude. The Amundsen-Scott research station at the pole is at 2,835 metres, perched on a sheet of glacier ice 2,700 metres above the bedrock, and moving towards the sea at 10 metres a year. Winter temperatures have fallen to minus 82.8°C. The warmest summer day ever recorded was minus 13.6°C. And yet this unforgiving spot, with an annual average temperature of minus 49°C, still registers a measure of global warming. Whether this warming is fuelled by a natural climate cycle or by the profligate human use of fossil fuels, or by both, is not certain.

Millions of people around the world could be exposed to dangerous levels of heat stress – a dangerous condition which can cause organs to shut down. Many live in developing countries, and do jobs that expose them to potentially life threatening conditions. These include being out in the open on farms and building sites or indoors in factories and hospitals. Global warming will increase the chances of summer conditions that may be “too hot for humans” to work in.
