NOAA’s latest monthly climate report confirms that 2015 will crush previous global temperature records.
That’s especially true up here in the northern hemisphere, where the first half of 2015 is a remarkable 0.36°F warmer than the first half of any year since records started being kept 135 years ago.
Here are some of the other records for “combined average temperature over global land and ocean surfaces” in the dataset for the month of June from the years 1880 to 2015:
- Hottest first half of any year (January-June) at “1.53°F (0.85°C) above the 20th century average … surpassing the previous record of 2010 by 0.16°F (0.09°C).”
- Hottest June at “1.58°F (0.88°C) above the 20th century average … surpassing the previous record set last year in 2014 by 0.22°F (0.12°C).”
Here is the Northern Hemisphere plot of historical temperatures for January through June showing the huge jump this year:
