Nobody denied climate change, there is scientific record of many ice ages. It's man-made climate change the politicians need to convince everybody as the cause. In order to do that, they have to prove that warming and cooling cycles of the earth were all normal cycles EXCEPT for the current cycle.
What temperature is the earth supposed to be in 2014? If the temperature is changing, what should it be? What is the normal rate global temperatures should rise and fall? How is that determined?
If Cissy were serious about LEARNING ABOUT CLIMATE CHANGE, I'd offer some information that might
inform him.
Cissy isn't interested in learning anything, he's interested in opposing everything, especially everything
supported by his govt.
For everyone else who may be interested:
Ninety-seven percent of climate scientists agree that climate-warming trends over the past
century are very likely due to human activities,1and most of the leading scientific organizations
worldwide have issued public statements endorsing this position. The following is a partial list
of these organizations, along with links to their published statements and a selection of
related resources.
American Association for the Advancement of Science
"The scientific evidence is clear: global climate change caused by human activities is
occurring now, and it is a growing threat to society." (2006)
American Chemical Society
"Comprehensive scientific assessments of our current and potential future climates clearly
indicate that climate change is real, largely attributable to emissions from human activities,
and potentially a very serious problem." (2004)
American Geophysical Union
"Human‐induced climate change requires urgent action. Humanity is the major influence
on the global climate change observed over the past 50 years. Rapid societal responses
can significantly lessen negative outcomes." (Adopted 2003, revised and reaffirmed 2007,
2012, 2013)
American Medical Association
"Our AMA ... supports the findings of the Intergovernmental Panel on Climate Change’s
fourth assessment report and concurs with the scientific consensus that the Earth is
undergoing adverse global climate change and that anthropogenic contributions are
significant." (2013)
American Meteorological Society
"It is clear from extensive scientific evidence that the dominant cause of the rapid change
in climate of the past half century is human-induced increases in the amount of atmospheric
greenhouse gases, including carbon dioxide (CO2), chlorofluorocarbons, methane, and nitrous
oxide." (2012)
American Physical Society
"The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are
taken, significant disruptions in the Earth’s physical and ecological systems, social systems,
security and human health are likely to occur. We must reduce emissions of greenhouse gases
beginning now." (2007)
The Geological Society of America
"The Geological Society of America (GSA) concurs with assessments by the National Academies
of Science (2005), the National Research Council (2006), and the Intergovernmental Panel
on Climate Change (IPCC, 2007) that global climate has warmed and that human activities
(mainly greenhouse‐gas emissions) account for most of the warming since the middle 1900s."
(2006; revised 2010)
International academies: Joint statement
"Climate change is real. There will always be uncertainty in understanding a system as complex
as the world’s climate. However there is now strong evidence that significant global warming
is occurring. The evidence comes from direct measurements of rising surface air temperatures
and subsurface ocean temperatures and from phenomena such as increases in average global
sea levels, retreating glaciers, and changes to many physical and biological systems. It is likely
that most of the warming in recent decades can be attributed to human activities (IPCC 2001)."
(2005, 11 international science academies)
U.S. National Academy of Sciences
"The scientific understanding of climate change is now sufficiently clear to justify taking steps
to reduce the amount of greenhouse gases in the atmosphere." (2005)
U.S. Global Change Research Program
"The global warming of the past 50 years is due primarily to human-induced increases in heat
-trapping gases. Human 'fingerprints' also have been identified in many other aspects of the
climate system, including changes in ocean heat content, precipitation, atmospheric moisture,
and Arctic sea ice." (2009, 13 U.S. government departments and agencies)
Intergovernmental Panel on Climate Change
“Warming of the climate system is unequivocal, as is now evident from observations of increases
in global average air and ocean temperatures, widespread melting of snow and ice, and rising global
average sea level.”13
“Most of the observed increase in global average temperatures since the mid-20th century is very
likely* due to the observed increase in anthropogenic greenhouse gas concentrations.”
*IPCC defines ‘very likely’ as greater than 90 percent probability of occurrence.List of worldwide scientific organizations
The following page lists the nearly 200 worldwide scientific organizations that hold the position
that climate change has been caused by human action.
