==Scientific opinion== {{See also|scientific opinion on climate change}} The IPCC is backed by the scientific community.<ref name="royal society misleading arguments">{{citation | date=13 April 2005 | author=Royal Society | at=[https://publications.parliament.uk/pa/ld200506/ldselect/ldeconaf/12/12we24.htm Letter from The Royal Society: A GUIDE TO FACTS AND FICTIONS ABOUT CLIMATE CHANGE: Misleading arguments: The IPCC has become too politicised and does not accurately reflect the wide range of views within the scientific community. The IPCC summary for policy-makers does not adequately represent the scientific uncertainty.] | title=Economic Affairs β Written Evidence }}, in {{harvnb|Economic Affairs Committee|2005}}. This document is also available in [http://royalsociety.org/Facts-and-fictions-about-climate-change/ PDF format] {{Webarchive|url=https://web.archive.org/web/20100210034153/http://royalsociety.org/Facts-and-fictions-about-climate-change/ |date=2010-02-10 }}</ref> For example, a joint statement of support was issued in May 2001 by the science academies of Australia, Belgium, Brazil, Canada, the Caribbean, China, France, Germany, India, Indonesia, Ireland, Italy, Malaysia, New Zealand, Sweden and the UK. It states: "We recognise the IPCC as the world's most reliable source of information on climate change and its causes, and we endorse its method of achieving consensus."<ref name="royal society misleading arguments"/> In 2001, the executive branch of the [[US federal government]] asked the [[US National Research Council]] (US NRC, 2001)<ref> {{citation | at=[http://www.nap.edu/openbook.php?record_id=10139&page=R7 p.VII] | title=Foreword }}, in {{harvnb|US NRC|2001}} </ref> to produce an assessment of climate change science. Part of the assessment by US NRC (2001)<ref name="us nrc 2001 summary p1"> {{citation | at=[http://www.nap.edu/openbook.php?record_id=10139&page=1 p.1] | title=Summary }}, in {{harvnb|US NRC|2001}} </ref> looks at the report produced by Working Group I (WG I) in the TAR. Working Group I's contribution to the TAR assesses the physical scientific aspects of the climate system and climate change. US NRC (2001)<ref name="us nrc 2001 summary p1"/> generally agrees with findings of the WG I report, for example, US NRC (2001)<ref> {{citation | at=[http://www.nap.edu/openbook.php?record_id=10139&page=3 p.3] | title=Summary }}, in {{harvnb|US NRC|2001}} </ref> state that "[the] IPCC's conclusion that most of the observed warming of the last 50 years is likely to have been due to the increase in greenhouse gas concentrations accurately reflects the current thinking of the scientific community on this issue." US NRC (2001)<ref name="us nrc 2001 ipcc assessment"> {{citation | at=[http://www.nap.edu/openbook.php?record_id=10139&page=22 pp.22-23] | title=7 Assessing Progress in Climate Science }}, in {{harvnb|US NRC|2001}} </ref> emphasise the need for governments to have a good understanding of uncertainties in climate change science. The example cited by US NRC (2001)<ref name="us nrc 2001 ipcc assessment"/> is the uncertainty over future changes in GHG emissions, which may be less or more than that projected by the TAR. US NRC (2001)<ref name="us nrc 2001 ipcc assessment"/> also state: <blockquote>The most valuable contribution U.S. scientists can make is to continually question basic assumptions and conclusions, promote clear and careful appraisal and presentation of the uncertainties about climate change as well as those areas in which science is leading to robust conclusions, and work toward a significant improvement in the ability to project the future.</blockquote>
