Temperatures Are Breaking Records Around The World
The 21st century has seen the most temperature records broken in recorded history. 2016 was the hottest year on record since 1880, according to Nasa and the National Oceanic and Atmospheric Administration (NOAA), with average temperatures measuring 1.78 degrees Fahrenheit (0.99 degrees Celsius) warmer than the mid-20th century mean. This makes 2016 the third year in a row to set a new record for global average surface temperatures. Since the 1950s, every continent has warmed substantially. NASA's latest visualisations, above, make that reality stark.
