I’m sure the
press will make this into a much bigger story. This today from NOAA News. The
choice of “hottest” in the title is interesting. We should ask our Canadian
friends if it was “hot” during March, since Canada seems to be leading the
world in “hotness” according to the NOAA image. – Anthony
NOAA: Global Temps Push Last Month to Hottest March on Record
combined global land and ocean surface temperature made last month the warmest
March on record, according to NOAA. Taken separately, average ocean
temperatures were the warmest for any March and the global land surface was the
fourth warmest for any March on record. Additionally, the planet has seen the
fourth warmest January – March period on record.
The monthly National Climatic Data Center analysis,
which is based on records going back to 1880, is part of the suite of climate
services NOAA provides government, business and community leaders so they can
make informed decisions.
Temperature Highlights – March 2010
anomaly is the difference from average, which gives a more accurate
picture of temperature change. In calculating average regional temperatures,
factors like station location or elevation affect the data, but those factors
are less critical when looking at the difference from the average.

- The combined global land
and ocean average surface temperature for March 2010 was the warmest on
record at 56.3°F (13.5°C), which is 1.39°F (0.77°C) above the 20th century
average of 54.9°F (12.7°C).
- The worldwide ocean surface
temperature was the highest for any March on record –1.01°F (0.56°C) above
the 20th century average of 60.7°F (15.9°C).
- Separately, the global land
surface temperature was 2.45°F (1.36°C) above the 20th century average of
40.8 °F (5.0°C) — the fourth warmest on record. Warmer-than-normal
conditions dominated the globe, especially in northern Africa, South Asia
and Canada. Cooler-than-normal regions included Mongolia and eastern
Russia, northern and western Europe, Mexico, northern Australia, western
Alaska and the southeastern United States.
- El Niño weakened to moderate
strength in March, but it contributed significantly to the warmth in the
tropical belt and the overall ocean temperature. According to NOAA’s
Climate Prediction Center, El Niño is expected to continue its influence
in the Northern Hemisphere at least through the spring.
- For the year-to-date, the
combined global land- and ocean-surface temperature of 55.3°F (13.0°C) was
the fourth warmest for a January-March period. This value is 1.19°F
(0.66°C) above the 20th century average.
- According to the Beijing
Climate Center, Tibet experienced its second warmest March since
historical records began in 1951. Delhi, India also had its second warmest
March since records began in 1901, according to the India Meteorological

- Arctic sea ice covered an
average of 5.8 million square miles (15.1 million square kilometers)
during March. This is 4.1 percent below the 1979-2000 average expanse, and
the fifth-smallest March coverage since records began in 1979. Ice
coverage traditionally reaches its maximum in March, and this was the 17th
consecutive March with below-average Arctic sea ice coverage. This year
the Arctic sea ice reached its maximum size on March 31st, the latest date
for the maximum Arctic sea ice extent since satellite records began in
- Antarctic sea ice expanse
in March was 6.9 percent below the 1979-2000 average, resulting in the
eighth smallest March ice coverage on record.
- In China, the Xinjiang
province had its wettest March since records began in 1951, while Jilin
and Shanghai had their second wettest March on record. Meanwhile, Guangxi
and Hainan provinces in southern China experienced their driest March on
record, according to the Beijing Climate Center.
- Many locations across
Ontario, Canada received no snow, or traces of snow, in March, which set
new low snowfall records, according to Environment Canada.
