30 Responses to NOAA: June is fourth month in a row of record global temperatures, first half of 2010 also on record pace
10 warmest years on record all since 1995
Here are some highlights and a fascinating chart comparing recent years:
- June was the fourth consecutive month that was the warmest on record for the combined global land and surface temperatures (March, April, and May were also the warmest). This was the 304th consecutive month with a combined global land and surface temperature above the 20th century average. The last month with below average temperatures was February 1985.
- It was the warmest June on record for the land surfaces of the globe. Previous record was set in 2005. The land surface temperature exceeded the previous record by 0.11ËšC (0.20ËšF). This large difference over land contributed strongly to the overall global land and ocean temperature anomaly….
- The year-to-date (January-June) combined global land and ocean temperature was the warmest on record…..
- 2010 surpassed 1998 (Feb, Jul, Aug) for the most “warmest months” in any calendar year….
- Each of the 10 warmest average global temperatures recorded since 1880 have occurred in the last fifteen years. The warmest year-to-date on record, through June, was 1998, and 2010 is warmer so far (note: although 1998 was the warmest year through June, a late-year warm surge in 2005 made that year the warmest total year):
“This graph plots the year-to-date average global land and ocean temperature. The 2010 value, complete only through June, is shown in red”
Given that a pretty big La Ni±a formed in 1998, and one is now forming today, it may end up pretty close between 2010 and 2005 and 1998.
The 2010 records are all the more powerful evidence of human-caused warming “because it occurs when the recent minimum of solar irradiance is having its maximum cooling effect,” as a recent must-read NASA paper notes.
