Why do cons continue to deny the scientific consensus on man made global warming?

1) THE AMERICAN CHEMICAL SOCIETY, FOUNDED IN 1876, OVER 160,000 MEMBERS

"There is now general agreement among scientific experts that the recent warming trend is real (and particularly strong within the past 20 years), that most of the observed warming is likely due to increased atmospheric greenhouse gas concentrations, and that climate change could have serious adverse effects by the end of this century."

http://www.chemistry.org/portal/resources/ACS/ACSC...

2) THE GEOLOGICAL SOCIETY OF AMERICA, FOUNDED IN 1888, OVER 20,500 MEMBERS

"The Geological Society of America (GSA) supports the scientific conclusions that Earth’s climate is changing; the climate changes are due in part to human activities; and the probable consequences of the climate changes will be significant and blind to geopolitical boundaries.

http://www.geosociety.org/aboutus/position10.htm

3) THE AMERICAN METEOROLOGY SOCIETY, FOUNDED IN 1919, OVER 11,000 MEMBERS

"Despite the uncertainties noted above, there is adequate evidence from observations and interpretations of climate simulations to conclude that the atmosphere, ocean, and land surface are warming; that humans have significantly contributed to this change; and that further climate change will continue to have important impacts on human societies, on economies, on ecosystems, and on wildlife through the 21st century and beyond."

4) THE U.S. NATIONAL ACADEMY OF SCIENCE (ALONG WITH THE NAS OF THE G8 NATIONS), FOUNDED IN 1863, OVER 2,000 MEMBERS, OVER 200 NOBEL PRIZE MEMBERS

"There is now strong evidence that significant global warming is occurring. It is likely that most of the warming in recent decades can be attributed to human activities. The scientific understanding of climate change is now sufficiently clear to justify nations taking prompt action.

5) THE AMERICAN GEOPHYSICAL UNION, FOUNDED IN 1919, OVER 45,000 MEMBERS

"Human activities are increasingly altering the Earth's climate. These effects add to natural influences that have been present over Earth's history. Scientific evidence strongly indicates that natural influences cannot explain the rapid increase in global near-surface temperatures observed during the second half of the 20th century.

http://www.agu.org/sci_soc/policy/climate_change_p...

6) THE INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE, CREATED IN 1988, HUNDREDS OF SCIENTISTS FROM OVER 130 NATIONS

"Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely (defined in footnotes as greater then 90% likelyhood) due to the observed increase in anthropogenic greenhouse gas concentrations. Discernible human influences now extend to other aspects of climate, including ocean warming, continental-average temperatures, temperature extremes and wind patterns"

7) THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE, FOUNDED IN 1848, SERVES 262 AFFILIATED SOCIETIES AND ACADEMIES OF SCIENCE FOR A TOTAL OF 10 MILLION INDIVIDUALS

"The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society. Accumulating data from across the globe reveal a wide array of effects: rapidly melting glaciers, destabilization of major ice sheets, increases in extreme weather, rising sea level, shifts in species ranges, and more. The pace of change and the evidence of harm have increased markedly over the last five years. The time to control greenhouse gas emissions is now."

8) THE NOAA'S NATIONAL CLIMATIC DATA CENTER PALEOCLIMATOLOGY PROGRAM, FOUNDED IN 1992, HAS THE LARGEST ARCHIVE OF CLIMATE AND PALEOCLIMATE DATA

"Many scientists have now concluded that global warming can be explained by a human-caused enhancement of the greenhouse effect. It is important to remember both that the greenhouse effect occurs naturally, and that it has been intensified by humankind's input of greenhouse gases into the atmosphere."

9) THE NATIONAL CENTER FOR ATMOSPHERIC RESEARCH, FOUNDED IN 1960, OVER 120 MEMBERS, SERVES OVER 62 PARTNER ORGANIZATIONS INCLUDING UNIVERSITIES AND RESEARCH CENTERS

"Together, these data show that Earth's surface air temperature has risen more than 1.1°F (0.7°C) since the late 1800s. This warming of the average temperature around the globe has been especially sharp since the 1970s. Global models at NCAR have simulated 20th century climate and found three main factors at work:

1) Solar activity contributed to a warming trend in global average temperature from the 1910s through 1930s.

2) As industrial activity increased following World War II, sun-blocking sulfates and other aerosol emissions helped lead to a slight global cooling from the 1940s to 1970s.

3) Since 1980, the rise in greenhouse gas emissions from human activity has overwhelmed the aerosol effect to produce overall global warming."

10) THE NASA'S GODDARD INSTITUTE FOR SPACE STUDIES, FOUNDED IN 1961, SPECIALIZES IN SPACECRAFT OBSERVATIONS AND GLOBAL CLIMATE MODELS

"A new NASA-funded study used a computer climate model to simulate the last 50 years of climate changes, projects warming over the next 50 years regardless of whether or not nations curb their greenhouse gas (GHG) emissions soon. If no emission reductions are made and they continue to increase at the current rate, global temperatures may increase by 1-2º Celsius (1.8º-3.6º Fahrenheit). But if the growth rate of carbon dioxide does not exceed its current rate and if the growth of true air pollutants (things that are harmful to human health) is reversed, temperatures may rise by only 0.75C (1.35F)."

genny,

The scientific consensus is based on the facts:

- temperature records

- balloon measurements

- satellite measurements

- ice core data (going back 1 million years)

- ocean sediment samples

- tree rings

- radiocarbon dating

- advanced climate models using the basical laws of physics run on supercomputers

and

- PEER REVIEW

working,

The only views that count are those who are doing the actual science. The vast majority of scientists support the scientific consensus that the earth is warming and that man is the main cause. A small minority has doubts.

Bluesteel,

Thank you for proving me right. You cited editorials, individual scientists, and political websites. The conservative book club?
