It ISN’T just the end of an ice age and all part of a long cycle.
Some comments need to be addressed to what was mentioned about the idea that global warming is not caused by human activity and just a normal cycle. It is funny how the blame for the global warming term is now being blamed on politicians.
In reality more politicians don’t want to touch the issue cause many get reelected with the campaign contributions from the huge oil and gas corporations. Many are afraid to speak out about the crisis we are experiencing because being reelected is more important then what happens down the road to our environment.
It was mentioned that, “the extinction of large animals in North America 10,000 years ago happened as a result of warming climate that no longer provided the habitat needed for the great mammoths, saber tooth tigers, and other large beasts.”
There happens to be even more evidence that part of the extinctions of these large mammals was brought on by over hunting and possible introduced viruses or diseases by man. These large mammals had survived for a couple million years with ice ages and warming trends coming and going. Even the wild horse became extinct after the last ice age, when man was present in their habitat. There are no wild horses in existence from the last ice age. Present day horses all come from domesticated versions of the wild horse.
Another comment was, “Changes in climate happen in cycles regardless of man’s intervention.” That is very true, but they haven’t happened at the accelerated rate that is occurring in the past 200 years. The extinction rate is much higher then in other equal previous periods of time.
Out of 13,950 scientific papers published between 1 January 1991 and 9 November 2012, it was found 24, or 0.17 percent, or 1 in 581, that clearly reject global warming or endorse a cause other than CO2 emissions for observed warming.
There is overwhelming scientific evidence among climatologists and other scientists that global warming is occurring and much is due to human activity.
Here are just some reputable organizations that back the scientific evidence that greenhouse gases emitted by human activity are the primary driver of global warming.
American Association for the Advancement of Science, American Chemical Society, American Geophysical Union, American Institute of Biological Sciences, American Meteorological Society, American Society of Agronomy, American Society of Plant Biologists, American Statistical Association, Association of Ecosystem Research Centers, Botanical Society of America, Crop Science Society of America, Ecological Society of America, Natural Science Collections Alliance, Organization of Biological Field Stations, Society for Industrial and Applied Mathematics, Society of Systematic Biologists, Soil Science Society of America, University Corporation for Atmospheric Research.
Show me a reputable scientific organization that denies that greenhouse gases, emitted by human activity, is not a primary driver of global warming.
Much climate change denial and funding for it has been associated with the energy lobby industry advocates and free market think tanks, most often in the United States. Also one of the main outspoken groups denying global warming is from conservative politicians as well. I wonder who is financing their reelections.
