NEWS FLASH

September 2012 Tied For The Warmest Ever Recorded | Last month was tied for the warmest September ever recorded globally, according to new data from the National Climatic Data Center. The average combined land and ocean surface temperature last month was 1.21 degrees F above the 20th century average — rivaling September of 2005 as the warmest on record.

In August, the National Climatic Data Center reported that June through August of 2012 was the warmest ever recorded for global land surface temperatures. When factored with ocean surface temperature, the average global temperature between June and August was the third warmest in recorded history. The summer of 2012 was also the third warmest ever recorded for the U.S. — only .2 degrees F lower than the summer of 1936, during the height of the Dust Bowl.

In early September, the climate center reported that January through August of this year was the most extreme for weather ever recorded for the U.S.

  1. A very bad sign considering the fact that ENSO is still neutral. When El Nino comes back, Earth will see even more record high temps.

    • Mulga Mumblebrain says:

      Maybe El Nino won’t come back. Maybe something new and virulent, as befits a new climate regime. Maybe El Diablo.

  2. NOT the warmest month ever; the warmest SEPTEMBER.

    • Stephen Lacey says:

      Yes, that was the original intent. However, the language was unclear and I tweaked it slightly to make it clearer. Thanks!

  3. Pangolin says:

    Is it just me or is every month lately the warmest X-month every recorded? Does somebody have a link where that data is presented in a accessible format?

    • Spike says:

      The August global report had this stunning fact:

      “August 2012 marks the 36th consecutive August and 330th consecutive month with a global temperature above the 20th century average.The last below-average August temperature was August 1976 and the last below-average temperature for any month was February 1985″
