Study: Global warming this century could lead to ‘hundreds of millions’ dead

House Energy and Commerce Committee backs 83 percent emissions cut by 2050

A new study published in the American Meteorological Society’s Journal of Climate warns that global climate change may actually be twice as detrimental as previously predicted, with temperatures climbing by as much as nine degrees by 2100, leading to mass migrations, wars and "hundreds of millions" dead.

"The research, conducted by the Massachusetts Institute of Technology (MIT), predicts a 90% probability that worldwide surface temperatures will rise more than 9 degrees (F) by 2100, compared to a previous 2003 MIT study that forecast a rise of just over 4 degrees," noted USA Today .

The paper added: "The Intergovernmental Panel on Climate Change in 2007 forecast a temperature rise of anywhere from 2 to 11 degrees by 2100 based on a variety of different greenhouse-gas-emissions scenarios."

"The new study was done using 400 applications of a computer model, which included looking at complicated factors such as atmospheric, oceanic and biological systems data, as well as global economic activity," noted Reuters .

The same day as the study was published, the House Energy and Commerce Committee approved, by a vote of 33 to 25, a plan to reduce America’s climate-driving emissions 83 percent by 2050.

"This bill, when enacted into law this year, will break our dependence on foreign oil, make our nation the world leader in clean energy jobs and technology, and cut global warming pollution," said committee chairman Henry Waxman (D-CA).

"The legislation has four titles," notes the Environmental News Service :

* A clean energy title that promotes renewable sources of energy, carbon capture and sequestration technologies, clean electric vehicles, and the smart grid and electricity transmission.

* An energy efficiency title that increases energy efficiency across all sectors of the economy, including buildings, appliances, transportation, and industry.

* A global warming title that places limits on emissions of heat-trapping pollutants and establishes a cap-and-trade system of limiting carbon emissions and trading in emissions allowances. This would cut global warming pollution by 17 percent compared to 2005 levels in 2020, by 42 percent in 2030, and by 83 percent in 2050. These are science-based targets and within the range agreed to by the U.S. Climate Action Partnership, USCAP, a coalition of some of America’s largest corporations and environmental NGOs.

* A title that protects U.S. consumers and industry and promotes green jobs during the transition to a clean energy economy.

"Friends of the Earth climate campaigner Tom Picken said that if the new research by MIT is accurate the results for the planet would be catastrophic," reported The Telegraph .

"A 7.4C rise would mean severe ecosystem collapse worldwide, with total economic collapse in many parts of the world," Picken told the paper. "The planet would face resource wars between people, and you can safely say many, many hundred of millions of people would die."

"Because vehicles last for years, and buildings and powerplants last for decades, it is essential to start making major changes through adoption of significant national and international policies as soon as possible," advised an MIT press release regarding the new study. "The least-cost option to lower the risk is to start now and steadily transform the global energy system over the coming decades to low or zero greenhouse gas-emitting technologies."
