Slight fluctuations from 1998’s record heat doesn’t mean warming is done


Sometimes you find rational discussion and good information in the newspaper.

This story moved on the McClatchy wire last August (I just recently came across it):

Drop in world temperatures fuels global warming debate

By Robert S. Boyd | McClatchy Newspapers

WASHINGTON — Has Earth’s fever broken?

Official government measurements show that the world’s temperature has cooled a bit since reaching its most recent peak in 1998.

That’s given global warming skeptics new ammunition to attack the prevailing theory of climate change. The skeptics argue that the current stretch of slightly cooler temperatures means that costly measures to limit carbon dioxide emissions are ill-founded and unnecessary.

Proposals to combat global warming are “crazy” and will “destroy more than a million good American jobs and increase the average family’s annual energy bill by at least $1,500 a year,” the Heartland Institute, a conservative research organization based in Chicago, declared in full-page newspaper ads earlier this summer. “High levels of carbon dioxide actually benefit wildlife and human health,” the ads asserted.

Many scientists agree, however, that hotter times are ahead. A decade of level or slightly lower temperatures is only a temporary dip to be expected as a result of natural, short-term variations in the enormously complex climate system, they say.

McClatchy’s story would be accurate today, even after the records show that the last decade is the hottest ever — such a long shelf-life shows good research and writing by McClatchy’s reporters.  McClatchy’s story doesn’t contradict this press release last week from the World Meteorological Organization (WMO):

2000–2009, THE WARMEST DECADE

Geneva, 8 December 2009 (WMO) – The year 2009 is likely to rank in the top 10 warmest on record since the beginning of instrumental climate records in 1850, according to data sources compiled by the World Meteorological Organization (WMO). The global combined sea surface and land surface air temperature for 2009 (January–October) is currently estimated at 0.44°C ± 0.11°C (0.79°F ± 0.20°F) above the 1961–1990 annual average of 14.00°C/57.2°F. The current nominal ranking of 2009, which does not account for uncertainties in the annual averages, places it as the fifth-warmest year. The decade of the 2000s (2000–2009) was warmer than the decade spanning the 1990s (1990–1999), which in turn was warmer than the 1980s (1980–1989). More complete data for the remainder of the year 2009 will be analysed at the beginning of 2010 to update the current assessment.

This year above-normal temperatures were recorded in most parts of the continents. Only North America (United States and Canada) experienced conditions that were cooler than average. Given the current figures, large parts of southern Asia and central Africa are likely to have the warmest year on record.

If only all reporting were so accurate.
