Last year was the hottest in recorded history
If you like warm weather, last year must have been a blast for you. It was the warmest year in recorded history.
NASA Goddard are reporting that 2016 was the hottest year in recorded history of mankind, again.
How do they know this? They have been monitoring the earths surface temperature from 3 sources:
- 6300 weather stations around the world
- Ship and buoy based observations of sea surface temperatures
- Temperature measurements from antarctic research stations
Recorded since 1880
Recordings of the earths temperature began back in 1880. The global average temperature in 2016 was 1.78 degrees (0.99 degrees celcius) hotter than they were back in the 20th century.
2016 is the third year in a row now that the earths average temperature sets a new record.
Because of the weather stations locations and measurement practices have change during the course of the years, its hard, even for NASA to get a good and accurate measurement to compare with, but even with these factors included, their scientists say that they with 95% accuracy concur that 2016 is the hottest year so far.
The earths temperature has risen by 2.0 degrees Fahrenheit (1.1 degrees celcius) since the 19th century, and most of it has happened during the last 35 years.
