NOAA: Global temperatures in March make coolest March since 1999 even with US’ record-breaking warmth

The average global temperature for March 2012 made it the coolest March since 1999, and the 16th warmest since record keeping began in 1880, according to the US National Oceanic and Atmospheric Administration (NOAA). At the same time, the contiguous US recorded warmest March on record since 1895. (Earlier post.)

Arctic sea ice extent during the month was below average but was the largest extent since 2008 and one of the largest March extents of the past decade, according to NOAA. Additionally, La Niña conditions continued to weaken during March as temperatures across the equatorial Pacific Ocean warmed during the last two months. According to NOAA’s Climate Prediction Center, La Niña is expected to dissipate by the end of April 2012.

Highlights of NOAA’s monthly report for March include:

  • The combined average temperature over global land and ocean surfaces for March 2012 was the 16th warmest March record and the coolest since 1999 at 55.73 °F (13.16 °C), which is 0.83 °F (0.46 °C) above the 20th century average of 54.9 °F (12.7 °C). The margin of error associated with this temperature is ±0.13°F (0.07°C).

  • The global land-only surface temperature was 1.31 °F (0.73 °C) above the 20th century average of 40.8 °F (5.0 °C), making it the 18th warmest March on record and the coolest global land-only March temperature anomaly since 2003. The margin of error is ±0.23 °F (0.13 °C).

  • Warmer-than-average conditions occurred across nearly all of Canada, the contiguous United States, Mexico, Europe, Argentina, Peru, and parts of northern and central Russia, India, China, and eastern Brazil. Cooler-than-average regions included Alaska, Australia, eastern and western Russia, and parts of New Zealand.

  • Norway experienced its warmest March since national records began in 1900, while Australia had its third coolest March maximum temperature since national temperature records began in 1950.

  • For the ocean, the March global sea surface temperature was 0.63 °F (0.35 °C) above the 20th century average of 60.7 °F (15.9 °C), tying with 1988 and 1990 as the 14th warmest March on record and coolest since 2008. The margin of error is ±0.07 °F (0.04 °C). The warmth was most pronounced across the north central Pacific, the North Atlantic, much of the eastern Indian Ocean, and portions of the mid-latitude Southern oceans.

The average March 2012 temperature in our area was by far the warmest on records. Five consecutive days over +25C in March never happened since records are kept.

In my city the icecream trucks are already making their rounds - I've seen them go pass my house for a third weekend in a row.

Sometimes people don't get it until it gets them;

The unfortunate fact is NOAA and IPC...er, can't remember the acronym for the defunct UN group - have lost all credibility. Climate is below zero on the chart of human concerns.

ai_vin

For the most part, anybody they might have lost credibility with - had none of their own and are not good judges of it.

Whether can be affected by climate change, it is the long and short term periodicity. The planet has a heat budget, when more comes in it has to be dealt with somehow. That could be tornadoes, hurricanes, droughts, floods or of methods.

The sad part of the deniers is they will not be around to explain their positions when the crops fail and there is no return nor remedy. At some point, open minded people should not listen to people that do not make any sense. They have nothing to add except the same old denial.

Come on guys... this all boils down to the inevitable movement to less gloom and doom. While this may not fit YOUR reality projection - it DOES fit those of growing human mindshare:

In spite of what some of you may think - the human race thinks otherwise. ALL are welcome. There's plenty for everyone!

ai_vin

You should worry more about YOUR credibility.

Reel$$

Who ME worry? It's unhealthy ai...;)

ai_vin

So is ignoring an existing problem.

Reel$$

People who THINK it's a problem ARE the problem. See my links. Things just aren't as gloomy as some wish they were!

ai_vin

Oh please! I saw your links and I know what you're doing, you're revisiting your Antarctica argument again, or as I like to called it: The "it's-cold-somewhere-in-the-world-so-it-can't-be-GLOBAL-warming" argument.

This was debunked and explained the first time you brought it up (as well as the second, third, etc. times) and YOU KNOW THAT. So for you to bring it up yet again proves you have no credibility left (as if you had any remaining after the Rossi debacle, the "volcanoes-emit-more-CO2" joke, the Roy Spencer blunder, the cosmic-ray overreach, and the list goes on and on) and if you're not worried about that... you have more of a problem than I care to deal with.

How does the thickening ice in the Himalayas appear to be the Antarctic to you ai?? Read the paper. It's COLD out there (for some esp;)
