Global warming is will set in on an obvious course after 2009. Researchers at
Britain's Met Office -- which deals with meteorology -- made a computer model that takes into account such natural phenomena as the El Nino pattern in the Pacific Ocean and other fluctuations in ocean circulation and heat content. Study author
Douglas Smith and his colleagues predicted that the next three or four years would show little warming. To check their models, the scientists used a series of "hindcasts" -- forecasts that look back in time -- going back to 1982, and compared what their models predicted with what actually occurred. The real heat will start after 2009, they said.
"There is ... particular interest in the coming decade, which represents a key planning horizon for infrastructure upgrades, insurance, energy policy and business development," Smith and his co-authors noted.

"Over the 100-year timescale, the main change is going to come from greenhouse gases that will dominate natural variability, but in the coming 10 years the natural internal variability is comparable," Smith said.
