First, the argument about global warming had not been up for debate. Most scientists agreed that global warming was occurring but not that it was manmade.
Turns out that global warming stopped in 1996. The fact is renewable energy is the driving force behind trying to prove a coming disaster because many people in the world of academia have been working on solutions for the coming energy crisis for some time. As early as even 1911 there was a belief that solar energy would be the way of the future as a renewable source. It was believed that coal would eventually run out and the other form would be needed. But other forms of energy have risen like Oil and natural gas. So all those that bought into and invested into renewable energy, making it become a reality had become a problem. So then in the 1950s and 1960s temperatures were dropping and an idea about carbon in the atmosphere from a study back in 1896 regarding combustible energy and the carbon produced was starting to be used as the blame. It was bringing on an ice age. Then in 1980 temperatures were on the rise and by the mid 1980s the idea about the coming ice age had all but died. Then in 1988 the temperature had been rising for the last 8 years and then global warming became the topic of discussion. Now for the past 16 years or since 1996 the temperature has stayed flat. No global warming no global cooling but we still are trying to make policy regarding a research that has no supporting evidence. Why you ask well the reason is simple and the reason is money. All the investments over the past nearly 100 years are not wasted. They need renewable energy to take off so they can make a profit and maintain credibility. They cannot afford to wait another 100 or more years before these things might, I repeat might, be needed. So they need policies to help force renewable energy on people because it is more expensive.

There is not one Scientific Society, not one National Academy of Science, and not one major University that denies the reality of AGW. Here is the statement of the Scientific Society with the largest number of scientists involved in climate study, the American Geophyical Union.
AGU Position Statement: Human Impacts on Climate
Human Impacts on Climate
Adopted by Council December 2003
Revised and Reaffirmed December 2007
The Earth's climate is now clearly out of balance and is warming. Many components of the climate systemincluding 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 seasonsare 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. Global average surface temperatures increased on average by about 0.6°C over the period 19562006. As of 2006, eleven of the previous twelve years were warmer than any others since 1850. The observed rapid retreat of Arctic sea ice is expected to continue and lead to the disappearance of summertime ice within this century. Evidence from most oceans and all continents except Antarctica shows warming attributable to human activities. Recent changes in many physical and biological systems are linked with this regional climate change. A sustained research effort, involving many AGU members and summarized in the 2007 assessments of the Intergovernmental Panel on Climate Change, continues to improve our scientific understanding of the climate.
During recent millennia of relatively stable climate, civilization became established and populations have grown rapidly. In the next 50 years, even the lower limit of impending climate changean additional global mean warming of 1°C above the last decadeis far beyond the range of climate variability experienced during the past thousand years and poses global problems in planning for and adapting to it. Warming greater than 2°C above 19th century levels is projected to be disruptive, reducing global agricultural productivity, causing widespread loss of biodiversity, andif sustained over centuriesmelting much of the Greenland ice sheet with ensuing rise in sea level of several meters. If this 2°C warming is to be avoided, then our net annual emissions of CO2 must be reduced by more than 50 percent within this century. With such projections, there are many sources of scientific uncertainty, but none are known that could make the impact of climate change inconsequential. Given the uncertainty in climate projections, there can be surprises that may cause more dramatic disruptions than anticipated from the most probable model projections.
With climate change, as with ozone depletion, the human footprint on Earth is apparent. The cause of disruptive climate change, unlike ozone depletion, is tied to energy use and runs through modern society. Solutions will necessarily involve all aspects of society. Mitigation strategies and adaptation responses will call for collaborations across science, technology, industry, and government. Members of the AGU, as part of the scientific community, collectively have special responsibilities: to pursue research needed to understand it; to educate the public on the causes, risks, and hazards; and to communicate clearly and objectively with those who can implement policies to shape future climate
