Well, you throw much out there as fact without one source to back up your clearly rehearsed religious talking points. But just answer this question...Have scientists ever been wrong?
j-mac
Of course scientists have been wrong. But they still represent by far the best, most informed opinion on the subject.
Okay, here goes.
Part I.
Academies of Science
European Academy of Sciences and Arts
In 2007, the European Academy of Sciences and Arts issued a formal declaration on climate change titled Let's Be Honest:
Human activity is most likely responsible for climate warming. Most of the climatic warming over the last 50 years is likely to have been caused by increased concentrations of greenhouse gases in the atmosphere. Documented long-term climate changes include changes in Arctic temperatures and ice, widespread changes in precipitation amounts, ocean salinity, wind patterns and extreme weather including droughts, heavy precipitation, heat waves and the intensity of tropical cyclones. The above development potentially has dramatic consequences for mankind's future.
InterAcademy Council
As the representative of the world's scientific and engineering academies, the InterAcademy Council (IAC) issued a report in 2007 titled Lighting the Way: Toward a Sustainable Energy Future.
Current patterns of energy resources and energy usage are proving detrimental to the long-term welfare of humanity. The integrity of essential natural systems is already at risk from climate change caused by the atmospheric emissions of greenhouse gases.
Concerted efforts should be mounted for improving energy efficiency and reducing the carbon intensity of the world economy.
International Council of Academies of Engineering and Technological Sciences
In 2007, the International Council of Academies of Engineering and Technological Sciences (CAETS) issued a Statement on Environment and Sustainable Growth
As reported by the Intergovernmental Panel on Climate Change (IPCC), most of the observed global warming since the mid-20th century is very likely due to human-produced emission of greenhouse gases and this warming will continue unabated if present anthropogenic emissions continue or, worse, expand without control.
CAETS, therefore, endorses the many recent calls to decrease and control greenhouse gas emissions to an acceptable level as quickly as possible.
Joint science academies' statements
Since 2001,
32 national science academies have come together to issue joint declarations confirming anthropogenic global warming, and urging the nations of the world to reduce emissions of greenhouse gases. The signatories of these statements have been the national science academies of Australia, Belgium, Brazil, Cameroon, Canada, the Caribbean, China, France, Ghana, Germany, Indonesia, Ireland, Italy, India, Japan, Kenya, Madagascar, Malaysia, Mexico, Nigeria, New Zealand, Russia, Senegal, South Africa, Sudan, Sweden, Tanzania, Uganda, United Kingdom, United States, Zambia, and Zimbabwe.
2001-Following the publication of the IPCC Third Assessment Report, sixteen national science academies issued a joint statement explicitly acknowledging the IPCC position as representing the scientific consensus on climate change science. The sixteen science academies that issued the statement were those of Australia, Belgium, Brazil, Canada, the Caribbean, China, France, Germany, India, Indonesia, Ireland, Italy, Malaysia, New Zealand, Sweden, and the United Kingdom.
2005-The national science academies of the G8 nations, plus Brazil, China and India, three of the largest emitters of greenhouse gases in the developing world, signed a statement on the global response to climate change. The statement stresses that the scientific understanding of climate change is now sufficiently clear to justify nations taking prompt action, and explicitly endorsed the IPCC consensus. The eleven signatories were the science academies of Brazil, Canada, China, France, Germany, India, Italy, Japan, Russia, the United Kingdom, and the United States.
2007-In preparation for the 33rd G8 summit, the national science academies of the G8+5 nations issued a declaration referencing the position of the 2005 joint science academies' statement, and acknowledging the confirmation of their previous conclusion by recent research. Following the IPCC Fourth Assessment Report, the declaration states, "It is unequivocal that the climate is changing, and it is very likely that this is predominantly caused by the increasing human interference with the atmosphere. These changes will transform the environmental conditions on Earth unless counter-measures are taken." The thirteen signatories were the national science academies of Brazil, Canada, China, France, Germany, Italy, India, Japan, Mexico, Russia, South Africa, the United Kingdom, and the United States.
2008-In preparation for the 34th G8 summit, the national science academies of the G8+5 nations issued a declaration reiterating the position of the 2005 joint science academies' statement, and reaffirming "that climate change is happening and that anthropogenic warming is influencing many physical and biological systems." Among other actions, the declaration urges all nations to "(t)ake appropriate economic and policy measures to accelerate transition to a low carbon society and to encourage and effect changes in individual and national behaviour." The thirteen signatories were the same national science academies that issued the 2007 joint statement.
2009-In advance of the UNFCCC negotiations to be held in Copenhagen in December 2009, the national science academies of the G8+5 nations issued a joint statement declaring, "Climate change and sustainable energy supply are crucial challenges for the future of humanity. It is essential that world leaders agree on the emission reductions needed to combat negative consequences of anthropogenic climate change". The statement references the IPCC's Fourth Assessment of 2007, and asserts that "climate change is happening even faster than previously estimated; global CO2 emissions since 2000 have been higher than even the highest predictions, Arctic sea ice has been melting at rates much faster than predicted, and the rise in the sea level has become more rapid." The thirteen signatories were the same national science academies that issued the 2007 and 2008 joint statements.
Network of African Science Academies
In 2007, the Network of African Science Academies submitted a joint "statement on sustainability, energy efficiency, and climate change" to the leaders meeting at the G8 Summit in Heiligendamm, Germany:
"A consensus, based on current evidence, now exists within the global scientific community that human activities are the main source of climate change and that the burning of fossil fuels is largely responsible for driving this change."
"The IPCC should be congratulated for the contribution it has made to public understanding of the nexus that exists between energy, climate and sustainability."
The thirteen signatories were the science academies of Cameroon, Ghana, Kenya, Madagascar, Nigeria, Senegal, South Africa, Sudan, Tanzania, Uganda, Zambia, Zimbabwe, as well as the African Academy of Sciences.
Royal Society of New Zealand [Yo KEN!
]
Having signed onto the first joint science academies' statement in 2001, the Royal Society of New Zealand released a separate statement in 2008 in order to clear up "the controversy over climate change and its causes, and possible confusion among the public":
The globe is warming because of increasing greenhouse gas emissions. Measurements show that greenhouse gas concentrations in the atmosphere are well above levels seen for many thousands of years. Further global climate changes are predicted, with impacts expected to become more costly as time progresses. Reducing future impacts of climate change will require substantial reductions of greenhouse gas emissions.
Polish Academy of Sciences
In December 2007, the General Assembly of the Polish Academy of Sciences (PAN) issued a statement endorsing the IPCC conclusions, and states:
"it is the duty of Polish science and the national government to, in a thoughtful, organized and active manner, become involved in realisation of these ideas".
"Problems of global warming, climate change, and their various negative impacts on human life and on the functioning of entire societies are one of the most dramatic challenges of modern times."
"PAS General Assembly calls on the national scientific communities and the national government to actively support Polish participation in this important endeavor."[23]
National Research Council (US)
In 2001, the Committee on the Science of Climate Change of the National Research Council published Climate Change Science: An Analysis of Some Key Questions. This report explicitly endorses the IPCC view of attribution of recent climate change as representing the view of the scientific community:
The changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability. Human-induced warming and associated sea level rises are expected to continue through the 21st century... 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.
