Is there scientific measurement data or test results that prove global warming on Earth is caused by C02 or any other greenhouse gas? An answer could include a reference to a journal article or possibly some commonly observable fact.

CO2 emissions are causing oceans to warm, ocean chemistry to change, and rainfall patterns to shift

The clearest evidence yet that Earth is warming and that CO2 emissions are largely responsible was presented by researchers in February at the annual meeting of the American Association for the Advancement of Science (AAAS), in Washington, D.C.

The researchers also presented evidence that increasing concentrations of atmospheric CO2 may be causing some biosystems, such as coral reefs, to approach the threshold for damage. If global temperatures rise more than 1.5 °C over today’s level, the world’s tropical coral reefs may be irreversibly destroyed, they said.

Beginning in the 1960s, the average temperatures of surface waters in all of the world’s major oceans began to rise, said Tim P. Barnett, research marine physicist at Scripps Institution of Oceanography. The results of computer models simulating the rise in ocean temperatures from increasing levels of atmospheric CO2 are nearly identical to temperature measurements taken since 1960 at various oceanic depths, he said.

“This is perhaps the most compelling evidence yet that global warming is happening right now, and it shows that we can successfully simulate its past and likely future evolution,” Barnett explained. For the Pacific, Atlantic, and Indian Oceans, graphs representing computer-generated temperatures are almost identical to the plots of actual temperatures, he observed. “The models have captured the observed warming with stunning realism.”

The warming experienced across the globe will have practical effects on water supplies, Barnett said. During the summer, 300 million people in China depend, in whole or in part, on melt water from glaciers for drinking and irrigation. By 2050, two-thirds of these glaciers will have disappeared, he noted.

There is ample evidence that the planetary water cycle is already altered as a result of global warming,” said Ruth Curry, research specialist in physical oceanography at Woods Hole Oceanographic Institution. In the past four decades, oceanic surface water at low latitudes has become markedly more saline, while the high-latitude surface ocean has become much fresher, she said.

Go to this web site:

http://www.ncdc.noaa.gov/paleo/icecore/antarctica/vostok/vostok_data.html

Download and plot the global temperature and atmospheric CO2 data and you will see that high CO2 and high temperatures occur at the same time as do low CO2 levels and low global temperatures.

The same goes for methane, another green house gas.

Go do a good study of plants and photosynthesis .I don't buy the global warming.
