US President Donald Trump and his administration may not believe in measures to protect Earth’s climate, but scientists are still concerned about global warming and its effect on our planet.

A time-lapse video created by Nasa shows how Earth’s surface temperatures have changed over the last 130 years.

The agency and the US National Oceanic and Atmospheric Administration (Noaa) have yet again confirmed that 2016 was the hottest year on record.

Nasa’s data shows the average global temperature in 2016 was 0.99C (1.78F) warmer than the mean temperature in the mid-20th century.

It might not sound like a large increase, but record years are part of a worrying long-term trend that could pose a threat to our survival.

Nasa points out: “The planet’s average surface temperature has risen about 1.1 Celsius (2.0F) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere.”

The map does not show temperatures itself but instead tracks the rise in temperatures. This is why the poles are much redder than the equator, where the temperatures are rising at a quicker rate.

Gavin Schmidt, director of Nasa’s Goddard Institute for Space Studies, said: “2016 is remarkably the third record year in a row in this series.

“We don’t expect record years every year, but the ongoing long-term warming trend is clear.”
