We are currently in an inter-glacial (glacier free) period of a long-term ice age.  Al Gore wants to doom our descendants to suffer through another glacial period, when most of earth's temperate zone would be covered by snow and ice.

In popular culture, there is often reference to "the next ice age."[22] Technically, since the earth is currently in an ice age, this usually refers to the next glacial period (because the earth is currently in an interglacial period).

The next glacial seemed rapidly approaching, when paleoclimatologists met in 1972 to discuss this issue (a period of so-called global cooling).[23][22] The previous interglacial periods seemed to have lasted about 10,000 years each.[22] Assuming that the present interglacial period would be just as long, they concluded, "it is likely that the present-day warm epoch will terminate relatively soon if man does not intervene."[24] Since 1972, our understanding of the climate system has improved. It is known that not all interglacial periods are of the same length and that solar heating varies in a non-linear fashion forced by the Milankovitch orbital cycles (see Causes section above). At the same time, it is also known that greenhouse gases are increasing in concentration with each passing year. Based on the variations in solar heating and on the amount of CO2 in the atmosphere, some calculations of future temperatures have been made. According to these estimates, the interglacial period the earth is in now may persist for another 50,000 years. That is, if CO2 levels increase to 750 parts per million (ppm). (The present atmospheric concentration of CO2 is about 385 ppm by volume,[25] but is rising rapidly as humans continue to burn fossil fuels.) If CO2 drops instead (to 210 ppm), then the next glacial period may only be 15,000 years away.

Moreover, studies of seafloor sediments and ice cores from glaciers around the world, namely Greenland, indicate that climatic change is not smooth. Studies of isotopic composition of the ice cores indicate the change from warm to frigid temperatures can occur in a decade or two.[26] In addition, the ice cores show that an ice age is not uniformly cold, nor are interglacial periods uniformly warm. Analysis of ice cores of the entire thickness of the Greenland glacier shows that climate over the last 250,000 years has changed frequently and abruptly. The present interglacial period (the last 10,000 to 15,000 years) has been fairly stable and warm, but the previous one was interrupted by numerous frigid spells lasting hundreds of years. If the previous period was more typical than the present one, the period of stable climate in which humans flourished--inventing agriculture and thus civilization--may have been possible only because of a highly unusual period of stable temperature.

Global warming is a good thing. Unless you already live in a desert. Which brings me back to my original statement.

I've been saying for years that everyone should thank us for Global warming, because without it we'd be in a frickin' Ice Age.


FUCK OBAMA

Speaking of Ice Ages -- 28 April 1975 Newsweek article

A survey completed last year by Dr. Murray Mitchell of the National Oceanic and Atmospheric Administration reveals a drop of half a degree in average ground temperatures in the Northern Hemisphere between 1945 and 1968. According to George Kukla of Columbia University, satellite photos indicated a sudden, large increase in Northern Hemisphere snow cover in the winter of 1971-72. And a study released last month by two NOAA scientists notes that the amount of sunshine reaching the ground in the continental U.S. diminished by 1.3% between 1964 and 1972.

To the layman, the relatively small changes in temperature and sunshine can be highly misleading. Reid Bryson of the University of Wisconsin points out that the Earth’s average temperature during the great Ice Ages was only about seven degrees lower than during its warmest eras — and that the present decline has taken the planet about a sixth of the way toward the Ice Age average.

And my favorite:

Climatologists are pessimistic that political leaders will take any positive action to compensate for the climatic change, or even to allay its effects.

They concede that some of the more spectacular solutions proposed, such as melting the Arctic ice cap by covering it with black soot or diverting arctic rivers, might create problems far greater than those they solve. But the scientists see few signs that government leaders anywhere are even prepared to take the simple measures of stockpiling food or of introducing the variables of climatic uncertainty into economic projections of future food supplies. The longer the planners delay, the more difficult will they find it to cope with climatic change once the results become grim reality.
