1 It's hot in here!

In fact, "It's the baseline, stupid." Claiming that present temperatures are warm requires a starting point at, say, the 1970s, or around the Little Ice Age (approximately 1200 A.D to the end of the 19th Century), or thousands of years ago. Select many other baselines, for example, compared o the 1930s, or 1000 A.D.-or 1998-and it is presently cool. Cooling does paint a far more frightening picture, given that another ice age would be truly catastrophic, while throughout history, warming periods have always ushered in prosperity. Maybe that's why the greens tried "global cooling" first.

The claim that the 1990s were the honest decade on record specifically targets the intellectually lazy and easily frightened, ignoring numerous obvious factors. "On record" obviously means a very short period, typically the past 100+ years, or since the end of the Little Ice Age. The National Academies of Science debunked this claim in 2006. Previously rural measuring stations register warmer temps after decades of "sprawl" (growth), cement being warmer than a pasture.

2 The science is settled-CO2 causes global warming.

Al Gore shows his audience a slide of CO2 concentrations, and a slide of historical temperatures. But for very good reason he does not combine them in one overlaid slide: Historically, atmospheric CO2, as often as not, increases after wanning. This is typical in the campaign of claiming "consensus" to avoid debate (consensus about what being left unspoken or distorted).

What scientists do agree on is little and says nothing about man-made global warming, to wit: (1) that global average temperature is probably about 0.6 degree Celsius-or 1 degree Fahrenheit-higher than a century ago; (2) that atmospheric levels of carbon dioxide have risen by about 30% over the past 200 years; and (3) that CO2 is one greenhouse gas, some level of an increase of which presumably would warm the Earth's atmosphere were all else equal, which it demonstrably is not.

Until scientists are willing to save the U.S. taxpayer more than $5 billion per year thrown at researching climate, it is fair to presume the science is not settled.

3 Climate was stable until man came along.

Swallowing this whopper requires burning every basic history and science text, just as "witches" were burned in retaliation for changing climates in ages (we had thought) long past. The "hockey stick" chart-poster child for this concept-has been disgraced and air-brushed from the UN's alarmist repertoire.

4 The glaciers are melting!

As good fortune has it. frozen things do in fact melt or at least recede after cooling periods mercifully end. The glacial retreat we read about is selective, however. Glaciers are also advancing all over, including lonely glaciers nearby their more popular retreating neighbors. If retreating glaciers were proof of global warming, then advancing glaciers are evidence of global cooling. They cannot both be true, and in fact, neither is. Also, retreat often seems to be unrelated to warming. For example, the snow cap on Mount Kilimanjaro is receding-despite decades of cooling in Kenya-due to regional land use and atmospheric moisture.

5 Climate change is raising the sea levels.

Sea levels rise during interglacial periods such as that in which we (happily) find ourselves. Even the distorted United Nations Intergovernmental Panel on Climate Change reports refute the hysteria, finding no statistically significant change in the rate of increase over the past century of man's greatest influence, despite green claims of massive melting already occurring. Small island nations seeking welfare and asylum for their citizens such as in socially generous New Zealand and Australia have no sea-level rise at all and in some cases see instead a drop. These societies' real problem is typically that they have made a mess of their own situation. One archipelago nation is even spending lavishly to lobby the European Union for development money to build beachfront hotel resorts, at the same time it shrieks about a watery and imminent grave. So, which time are they lying?

6 Global warming has doomed the polar bears!

For some reason, Al Gore's computerized polar bear can't swim, unlike the real kind, as one might expect of an animal named Ursa Maritimus. On the whole, these bears are thriving, if a little less well in those areas of the Arctic that are cooling (yes, cooling). Their biggest threat seems to be computer models that air-brush them from the future, the same models that tell us it is much warmer now than it is. As usual in this context, you must answer the question: Who are you going to believe-me or your lying eyes?

7 Global warming means more frequent, more severe storms.

Here again the alarmists cannot even turn to the wildly distorted and politicized "Summary for Policy Makers" of the UN's IPCC to support this favorite chestnut of the press.
