"What is clear from the record going back over nearly four decades is that White House science czar John Holdren is a climate alarmist, even if he can’t make up his mind whether the crisis is the Earth warming up or cooling down.

But long before Holdren was the global warming Cassandra he is today, he was a global cooling alarmist predicting a new ice age.

The only consistency seems to be that Holdren has always utilized climate hysteria to argue that government must mandate public policy measures to prevent imminent and otherwise unavoidable climate catastrophes.

In the 1970s, Holdren’s theme was that government-mandated population control was essential to prevent “eco-disasters” such as the foreseen coming new ice age; today Holdren urges immediate passage of the Obama administration’s proposed cap-and-trade legislation to control carbon emissions before it is too late to save the planet from global warming.

The new ice age Holdren predicted in the 1970s failed to materialize, just as WND has reported an increasing number of scientists are discounting claims mankind has significant influence on global climate.

Still, Holdren remains a climate alarmist, now with an important government policy position as science czar in the Obama White House."

Here's some real, potential Winger Global Cooling (North Atlantic mostly) for you to ponder. (Do wingers ponder?)

Another theory proposed by Ewing and Donn in 1956 hypothesized that an ice-free Arctic Ocean leads to increased snowfall at high latitudes. When low-temperature ice covers the Arctic Ocean there is little evaporation or sublimation and the polar regions are quite dry in terms of precipitation, comparable to the amount found in mid-latitude deserts. This low precipitation allows high-latitude snowfalls to melt during the summer. An ice-free Arctic Ocean absorbs solar radiation during the long summer days, and evaporates more water into the Arctic atmosphere. With higher precipitation, portions of this snow may not melt during the summer and so glacial ice can form at lower altitudes and more southerly latitudes, reducing the temperatures over land by increased albedo. Furthermore, under this hypothesis the lack of oceanic pack ice allows increased exchange of waters between the Arctic and the North Atlantic Oceans, warming the Arctic and cooling the North Atlantic. (Current projected consequences of global warming include a largely ice-free Arctic Ocean within 5–20 years). Additional fresh water flowing into the North Atlantic during a warming cycle may also reduce the global ocean water circulation. Such a reduction, by reducing the effects of the Gulf Stream, would have a cooling effect on northern Europe, which in turn would lead to increased low-latitude snow retention during the summer. It has also been suggested that during an extensive glacial period, glaciers may move through the Gulf of Saint Lawrence, extending into the North Atlantic ocean far enough to block the Gulf Stream.
