Increases in CO2 - Causes Cooling

  • Statement on climate change from 18 scientific associations
    "Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver." (2009)2

  • AAAS-emblem-with-canvas-border.jpg

    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)3

  • ACS-emblem-with-canvass-border.jpg

    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)4

  • AGU-emblem-with-canvas-border.jpg

    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)5

  • AMA-emblem-with-canvas-border.jpg

    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)6

  • AMS-emblem-with-canvass-border_133x75.jpg

    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)7

  • APS-emblem-with-canvass-border.jpg

    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)8

  • GSA-emblem-with-canvass-border.jpg

    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)9


SCIENCE ACADEMIES

  • 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)10

  • USNAS-emblem-with-canvass-border_133x75.jpg

    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)11


U.S. GOVERNMENT AGENCIES

  • USGCRP-emblem-with-canvas-border.jpg

    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)12


INTERGOVERNMENTAL BODIES

  • IPCC-emblem-with-canvass-and-border.jpg

    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.”14

    *IPCC defines ‘very likely’ as greater than 90 percent probability of occurrence.

RSS data is industry standard data. The chart is of RSS data.
I post the the chart because it shows the model failed.
the models are the only science you have for saying man made co2 causes warming.

The models have failed for another 2 years since this chart.

Another deceptive chart. Data set not from thermometers. These data sets have the most error rate and show the least temp gain.

They are deceptive so of course they are the ones you choose. You have no interest in the facts.

Finally, the IR radiation is not absorbed by nitrogen, oxygen, and argon gases which make up 99% of the atmosphere, so a large fraction of it directly warms the Earth's surface. Some, is absorbed by the dominant greenhouse gas, water vapor, and small amounts are absorbed by carbon dioxide and other greenhouse gases. The incoming IR radiation absorbed in the atmosphere is less effective in warming the Earth's surface than is that which is absorbed by the Earth's surface directly. This is because some this energy absorbed in the atmosphere then is radiated again in the form of IR radiation, but now half or more of that is directed out to space. In other words, more water vapor and CO2 in the atmosphere results in a less effective warming of the surface than does less of these gases with respect to the incoming IR energy from the sun. The greenhouse gases have a cooling effect on the original solar radiance spectrum for the 45% of the solar energy in the form of IR.

Jem it is important to recognize the difference between the effect of these gases in the outer reaches of the atmosphere and their effect near the earths surface. It is true that these gases have a shielding effect in the outer atmosphere, but their affect is different near the earths surface. They don't act as a greenhouse gas in the outer atmosphere where they instead act as a shield against incoming ir radiation from the sun, as you have pointed out. They would also, in the outer atmosphere, absorb some uv in the vacuum uv region. I am led to believe, by the experts, that on balance their net effect is slightly warming.

denier liars like jerm conveniently leave out the most accurate, actual thermometer based reading. There has been no slowdown of the earth's warming at all. In fact it is speeding up.

wow are you a deceptive troll. I already showed earlier on this thread or another the data is virtually the same.

I have told him that multiple times. It does not matter. Like you, he is not interested in the facts.
 
I now expect that piehole, having pretended to be reasonable and even handed, will say something like "There are no positive feedback processes at work in global warming" or something similarly absurd and he will refer to one the handful of fools, whores and frauds that are used by the denial machine to support their otherwise untenable position
