What 95% certainty of warming means to scientists

Discussion in 'Politics' started by futurecurrents, Sep 24, 2013.


  1. No. YOU say there is no science proving CO2 causes warming. The scientists say otherwise. I linked you to the science. You choose to ignore it and call NASA fraudulent. I am more convinced than ever that you are simply insane.

    You remind me of this guy.....

  2. Like a crazy broken record. Here's what NASA says

    "Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities,

    and 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 SCIENTIFIC SOCIETIES
    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
    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
    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
    American Geophysical Union
    "The Earth's climate is now clearly out of balance and is warming. Many components of the climate system — including the temperatures of the atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the sea level, the distribution of precipitation, and the length of seasons — are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century." (Adopted 2003, revised and reaffirmed 2007)5
    AMA emblem
    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
    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
    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
    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
    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

    you are such a troll..

    1. i granted you the science that greenhouses gases can keep some warmth in.

    2. NASA showed with science and you must agree that in an upper layer CO2 repels some solar energy.

    So... the question is what is the net effect on the earth's temperature when you add co2 to the atmosphere...

    the truth is that science does not know...

    you produced no other science viable science...

    the rest of your link was just speculative numbers plugged into a energy budget formula. The recent lack of warming showed those numbers to be ridiculous guesses.

    the moon gets up to 105 during the day... what moderates the earths temps... greenhouses gases....

    here is a comment from and excellent exchange on your link at skeptical science...

    @Ricardo At 15 microns the sun produces 180 times as much energy as the earth.

    It is irrelevant how much energy the sun produces in the visible, it is the energy emmitted by the earth and absorbed by CO2 which is key.

    Your Siki link states: "Thus heat is easily let in, but is partially trapped by these gasses as it tries to leave. "

    This isnt true. Visible energy is let in, not heat. The heat of the sun is bloocked by the same GH gasses as block the heat going out.

    The difference is that thr sun produces far more heat than the earth. The net effect of GH ghasses is therefore to reduce the maximum temperaturs that would be otherwise acchieved,

    Consider the moon,. Its daytime temperature is 105`C. It gets this hot because it hasnt got an atmosphere."

  5. Just cut the shit- when do we all start on fire?

  6. Are these the same 95% from 1970 who told us the world would be frozen over by the beginning of the 21st century if we didn't do something, NOW?
    There is only one solution according the the leftists. We must tax Americans into a third world status while igoring the fact that Russia, China, and India are the bigger problem. It is the final solution. Comrade Gore said so.

    I was looking around the internet the other day and now the left is saying that it is a myth that global cooling was predicted in the 70's.

    These people are just pathological liars.

  8. FC how many scientists agreed that the temperatures would be much warmer now than they actually are? I bet it's above 90%.

    Also, the heat being trapped in the Pacific is merely a theory. Ie. a guess. No proof.

    LOL idiot.

    The recent peer reviewed study would say that a third at most of the papers would have made that prediction because the large majority understood the sun and the tides played a big role and there was no science showing man made co2 had a significant influence.

  10. I know the denialist Republicans here are too fucking stupid to understand this chart but maybe some others may get something out of it.
