The Northern Hemisphere briefly emerged from the last ice age some 14,700 years ago with a 22-degree-Fahrenheit spike in just 50 years, then plunged back into icy conditions before abruptly warming again about 11,700 years ago.
Massive “reorganizations” of atmospheric circulation coincided with each temperature spurt, with each reorganization taking just one or two years, according to a new study.
Wind energy reduces carbon dioxide emissions and cuts natural gas and water use. Of particular interest to investors, wind power is unaffected by price swings in natural gas, coal and uranium — all of which soared this year.
The new filings reflect the deepening role of wind in the battle against climate change.
But what was unusual, and surprising, was the prominent role of economists as measured by the statement that acting quickly to cut emissions “would be the most cost-effective way to limit climate change.”
The humble bucket turns out to be at the bottom of a perplexing anomaly in the climate records for the twentieth century.
Land and ocean temperature measurements show a strange cooling of about 0.3 °C in the global mean temperature in 1945. A US–British team of climate scientists has now found a surprisingly simple explanation for the long-standing conundrum. It turns out that the mysterious drop is due to differences in the way that British and US ships' crews measured the sea surface temperature (SST) in the 1940s.
After virtually abandoning the issue for three decades, the environmental movement got a bold reality check this week from a new book highlighting relentless human population growth as a driving force behind global warming.
This wouldn’t have raised eyebrows in the 1970s, when the modern environmental movement had its genesis and Paul Erlich’s “The Population Bomb” was on just about everybody’s bookshelf.
Since then, however, overpopulation has dropped from the vocabulary of most environmentalists despite a near doubling of the world’s numbers to an estimated 6.8 billion people today.
In sharp contrast to denier’s claims that action against global warming will trigger economic catastrophe, a new study has concluded it would actually be cheaper to cut greenhouse-gas emissions than to suffer the consequences of a changing world.
In fact, the report by economists at Tufts University warns, “The longer we wait, the more painful and expensive the consequences will be.”
Democracy is utterly dependent upon an electorate that is accurately informed. In promoting climate change denial (and often denying their responsibility for doing so) industry has done more than endanger the environment. It has undermined democracy.
There is a vast difference between putting forth a point of view, honestly held, and intentionally sowing the seeds of confusion. Free speech does not include the right to deceive. Deception is not a point of view. And the right to disagree does not include a right to intentionally subvert the public awareness.
