Ag Weather Forum

A couple items on the climate scene are worth noting.

First--this item from the Associated Press on greenhouse gas content around the world.

GENEVA (AP) -- The U.N. weather agency says concentrations of the main global warming pollutant in the world's air reached a record high in 2011.

The World Meteorological Organization says the planet averaged 390 parts per million of heat-trapping carbon dioxide in the atmosphere, up 40 percent from before the Industrial Age when levels were about 275 parts per million.

WMO officials said Tuesday there was a 30 percent increase in the warming effect on the global climate between 1990 and 2011, mainly due to carbon dioxide from fossil fuel burning.

WMO Secretary-General Michel Jarraud said the 350 billion metric tons of carbon dioxide added to the atmosphere since 1750 "will remain there for centuries, causing our planet to warm further and impacting on all aspects of life on earth."

And second--the NOAA October climate report highlights continued warming around the world. World temperatures in October were above normal for the 332nd consecutive month--which amounts to 27.6 years straight. Here is a portion of the introduction to the report:

"The average temperature across land and ocean surfaces during October was 14.63°C (58.23°F). This is 0.63°C (1.13°F) above the 20th century average and ties with 2008 as the fifth warmest October on record. The record warmest October occurred in 2003 and the record coldest October occurred in 1912. This is the 332nd consecutive month with an above-average temperature. The last below-average month was February 1985. The last October with a below-average temperature was 1976. The Northern Hemisphere ranked as the seventh warmest October on record, while the Southern Hemisphere ranked as second warmest, behind 1997.

The average global temperature over land was 0.92°C (1.66°F) above average, making this the eighth warmest October on record. Several regions around the globe were much warmer than average, including northeastern and southwestern North America, most of South America, northern Africa, southeastern Europe, southwestern Asia, and far eastern Russia. A heat wave brought record warmth to large areas of Brazil and Bolivia. Record heat was also present in southern India. It was cooler than average in parts of northern Siberia, Mongolia, and northern China along with much of central North America. Western Canada was much cooler than average."
