According to temperature reconstruction made within an [[Old Earth]] paradigm, there have been many cycles of naturally-caused global warming and cooling over many millions of years (see [[climate cycles]]). Some scientists, including [[Richard Lindzen]] of [[MIT]], [[Sallie Baliunas]] of [[Harvard]] and [[Fred Singer]] (independent), say that the recent warming could be part of another natural cycle or random fluctuations in the atmosphere. However, many scientists also think that human activities were most likely the cause of the the planet's recent warming.

:Indeed, a recent Gallup poll of climate scientists in the American Meteorological Society and in the American Geophysical Union shows that a vast majority doubts that there has been any identifiable man-caused warming to date (49 percent asserted no, 33 percent did not know, 18 percent thought some has occurred; however, among those actively involved in research and publishing frequently in peer-reviewed research journals, none believes that any man-caused global warming has been identified so far). <ref>http://www.cato.org/pubs/regulation/regv15n2/reg15n2g.html</ref>

Oddly enough, even though 82% of US climate scientists refused to support the global warming theory then, liberal activists were already claiming a scientific consensus for [[anthropogenic global warming]]. (It's hard to understand how 18 percent credence in ''any'' global warming translates into "consensus" support for ''human-caused'' global warming.)

Clearly, "global warming" is a tempting issue for many very important groups to exploit.

... dealing with the threat of warming fits in with a great variety of preexisting agendas [like] dissatisfaction with industrial society (neopastoralism), ... governmental desires for enhanced revenues (carbon taxes), and bureaucratic desires for enhanced power. <ref>http://www.cato.org/pubs/regulation/regv15n2/reg15n2g.html</ref>

The global average surface temperature warmed about 0.9&nbsp;°F over the second half of the 20th Century.

Assessments of climate science by the [[United Nations]] (see [[IPCC]] - ''Intergovernmental Panel on Climate Change'')

Assessments of climate science by the [[United Nations]] (see [[IPCC]] - ''Intergovernmental Panel on Climate Change'')

have claimed that scientists are 90% sure that over 50% of the observed global warming in recent decades is human-caused, and that continued global warming should be expected over at least the next century. ''Science'' published a literature search by Naomi Oreskes concluding that "scientific consensus" supports the IPCC reports. <ref>http://www.sciencemag.org/cgi/content/full/306/5702/1686]</ref>

Several prominent scientists have pointed out the [[politicized science]] of the UN's assessment methods. The scientific reports are submitted to a panel of representatives appointed by each country in the IPCC. Several scientists whose research demonstrates that climate change is taking place have complained about their work being misrepresented by the U.N.

*In addition, a number of the participants have testified to the pressures placed on them to emphasize results supportive of the current scenario and to suppress other results. That pressure has frequently been effective, and a survey of participants reveals substantial disagreement with the final report. <ref>http://www.cato.org/pubs/regulation/regv15n2/reg15n2g.html</ref>

*[[Al Gore]] claims that Himalayan glaciers are shrinking and global warming is to blame.

<!-- This is wrong. Read the paper and you will see that it never claimed anything which contradicted global warming theory; indeed, the anomalous growing of these particular glaciers was expected. -->

*Gore claims the snow cap atop Africa's Mt. Kilimanjaro is shrinking and that global warming is to blame. Yet according to the November 23, 2003, issue of Nature magazine, "Although it's tempting to blame the ice loss on global warming, researchers think that deforestation of the mountain's foothills is the more likely culprit. Without the forests' humidity, previously moisture-laden winds blew dry. No longer replenished with water, the ice is evaporating in the strong equatorial sunshine." <ref>http://www.suntimes.com/news/otherviews/450392,CST-EDT-REF30b.article</ref>
