The Earth's temperature hasn't increased significantly in about 15 years, which wouldn't be big news except global warming extremists had predicted temperatures would soar during that time because of manmade greenhouse-gas emissions.

That forecast would be just another failed hypothesis, except governments around the world used the threatened overheating as an excuse to regulate, tax and subsidize in order to curb greenhouse gases and, of course, to save the Earth.

In 1989 the Miami Herald quoted a U.N. environment official who warned of a "10-year window of opportunity to solve" global warming, because "entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend is not reversed by the year 2000." We know how that turned out.

There are new forecasts today. We're not much more confident about them, but considering how far down the costly road to combating global warming the world has gone, they are worth noting.

Great Britain's heretofore hotbed of global warming alarmism, East Anglia's Climate Research Center, now says there been no meaningful warming since 1997. Indeed, the Earth may even be cooling, according to Britain's Meteorological Office. The Met, as it's called, said we are entering a period of slower solar activity, perhaps as severe as the solar slump from 1645-1715, the coldest part of the Little Ice Age, when Britain's river Thames and Holland's canals froze over.

Warmists may have seen this coming. Five years ago, climate scientist Kevin Trenberth lamented that none of the touted computer models that predicted temperature increases "correspond even remotely to the current observed climate." If temperatures merely stay flat, the difference between real temperatures and what the global warming models predict "will eventually become so great that the whole scientific community will question the current theories," said Duke University scientist Nicola Scafetta, whose specialty is theoretical and applied statistics.

The New York Times reported that "wind and solar companies are telling Congress that they cannot be truly competitive and keep creating jobs without a few more years of government support," but the lobbying "comes at a time when there is little enthusiasm for alternative-energy subsidies in Washington."

Sixteen noteworthy scientists published a statement last week in the Wall Street Journal, pooh-poohing global warming alarmism, assuring the public, "there's no compelling scientific argument for drastic action to 'decarbonize' the world's economy."
