It is a stark warning of how the earth’s temperature has risen since records began in 1880.
Nasa has created a video showing the changes until the present day – all condensed into just 26 seconds.
It shows that as greenhouse gas emissions from energy production, industry and vehicles have increased, temperatures have climbed – with a huge peak in the 1970s.
The video uses Nasa temperature data to create a stunning visual explanation of global warming. Here, in 1888 when records began, it reveals how cool the global temperature was.
Nasa’s Goddard Institute for Space Studies (GISS) in New York, which monitors global surface temperatures on an ongoing basis, created the video to show how Earth continues to experience warmer temperatures than several decades ago.
‘We know the planet is absorbing more energy than it is emitting,’ GISS Director James Hansen said at the video’s launch.
‘So we are continuing to see a trend toward higher temperatures.
‘Even with the cooling effects of a strong La Niña influence and low solar activity for the past several years, 2011 was one of the 10 warmest years on record.’
By 1915, temperatures can be seen heating up in some parts of the world.
The difference between 2011 and the warmest year in the GISS record (2010) is 0.22 degrees F (0.12 C).
The first 11 years of the 21st century experienced notably higher temperatures compared to the middle and late 20th century, Hansen said.
The average temperature around the globe in 2011 was 0.92 degrees F (0.51 C) warmer than the mid-20th century baseline.
In this animation of temperature data from 1880-2011, reds indicate temperatures higher than the ave rage during a baseline period of 1951-1980, while blues indicate lower temperatures than the baseline average.
