Is there any credible evidence that the increase CO2 levels in the atmosphere is not the cause of global warming?

In 1824 Fourier calculates that the Earth would be far colder if it lacked an atmosphere.  In 1859 Tyndall demonstrates that some gases block infrared radiation, and notes that changes in the concentration of the gases could bring climate change.

Is there any other reason why the earth is warming?

    in 30 years there has not been one study published in a credible scientific journal that overturns the central thesis that warming we are seeing now is due to the man-made release of greenhouse gases. A handful of unpublished fringe scientists funded by the fossil fuel industry are taken by morons as the gospel, and no doubt we'll get some of their discredited false ideas regurgitated by them in this question

    Because of tax records and usage records we know how much fossil fuel has been burned since the beginning of the Industrial Age.  We also know how much CO2 that burning generated.  We also know that the amount of CO2 in our paper thin atmosphere has increased since the advent of the Industrial Age.  From 286ppm in 1850 to 350ppm in 1950 to 415ppm today.  At the current rate of increase we will reach 450ppm by 2050...the foothills of a runaway heating event.  This doesn't include the rate of increase in the overall atmospheric methane load... another greenhouse gas.

    Some say the 'greenhouse gas' business is a ho-ax!  Most scientists understand that it's a scientific fact.  Adding CO2 and methane to the atmosphere WILL have a negative effect on life on this planet no matter how many deniers are out there.

    Good scientific theories are said to have ‘predictive power’. In other words, armed only with a theory, we should be able to make predictions about a subject. If the theory’s any good, the predictions will come true.

    Here’s an example: when the Table of Elements was proposed, many elements were yet to be discovered. Using the theory behind the Periodic Table, the Russian chemist Dmitri Mendeleev was able to predict the properties of germanium, gallium and scandium, despite the fact they hadn’t been discovered.

    It has actually been proven with greater than a 99% confidence level that natural variation is NOT the cause of the warming that's been seen.

    But look at the level of scientific knowledge you're dealing with in this group--Pindar seems to think there is actually some question as to whether or not the planet has warmed. Here's a homework exercise for you, Pindar, find a measure of global mean temperature--just one is enough--that supports your claim. You won't, because there aren't any. Sea level rise is accelerating for a reason, alpine glaciers are retreating for a reason, Greenland is losing ice for a reason--see if you can figure out what that reason is.

    What warming?       Is there any credible unmanipulated evidence that it’s significantly warmed?

    Still doesn't matter, Dirac.  There are no negative effects cited in peer review.  I have cited these dozens of studies in detail over the past months.  You have not addressed one of them.

    CO2 gas is absorbed by plants, but CH4 and hydrocarbons don't go anywhere, it should be the main concern.

    Conservatives these days don't do credible evidence, they do conspiracy theories.  If a conservative can spend 30 seconds manufacturing a conspiracy theory ("scientists all say that to get funding") they don't feel the need to address the mountains of data (see below).

    The global warming / climate change we're seeing in the last 100 or so years is MUCH different from anything measured in the glacial & sea sediment records covering the last 700,000 years.  CO2 is rising 100x faster, and temps 10x faster.

    "How is Today’s Warming Different from the Past?"    "As the Earth moved out of ice ages over the past million years, the global temperature rose a total of 4 to 7 degrees Celsius over about 5,000 years. In the past century alone, the temperature has climbed 0.7 degrees Celsius, roughly ten times faster than the average rate of ice-age-recovery warming."

    How is today's CO2 increase different?  "The annual rate of increase in atmospheric carbon dioxide over the past 60 years is about 100 times faster than previous natural increases, such as those that occurred at the end of the last ice age 11,000-17,000 years ago."

    Fact is, anthropogenic global warming is accepted by a YUGE segment of the scientific community. Would you accept the consensus opinion of the American Physical Society AND the American Chemical Society? How about the American Association for the Advancement of Science, and at least 15 other national organizations of publishing scientists? See
