Line 34:
Line 34: − + − − A [[United Nations]] panel ([[IPCC]]) asserts that most of the warming since around 1850 is human-caused. Global warming proponents call this panel "authoritative". Others question its objectivity, and a handful of scientists have resigned from the panel in protest over unauthorized changes in scientific reports. − − In February, 2007, the [[IPCC|Intergovernmental Panel on Climate Change]], whose members were appointed by their governments, released their fourth assessment report on climate change. That report concluded that most of recent global warming was "very likely" caused by human activity<ref>http://news.bbc.co.uk/2/hi/science/nature/6321351.stm</ref>. It says that increases in atmospheric concentrations of [[greenhouse gas]]es cause warming. Several members of this panel later complained their contributions were misrepresented in the final report. − − ===IPCC controversy=== − A reporter for the ''Chicago Tribune'' called the IPCC "the top body of climate change scientists in the world". <ref>http://www.chicagotribune.com/news/nationworld/chi-0704280477apr29,1,4275902.story?coll=chi-newsnationworld-hed</ref> − − Fred Singer and other scientists dispute this view. <!-- I need to supply some quotes from Singer and Lindzen. The IPCC is not just scientists, in fact not even mostly climatologists. It supports a pre-ordained conclusion. It ignores contrary data. --> − <!-- Backing evidence for this claim? -->
The IPCC is a political group, not a scientific body
Nonetheless, controversy has persisted over the influence of urban warming on reported large-scale surface-air temperature trends. <ref name="col" />

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.
