do they not keep up with the facts? do they want instant change? it seems they want to come here and bitch at us when in reality the changes are required elsewhere and more importantly, are in fact happening.

Rare optimism ahead of climate talks in Lima
Pledges by Chinese President Xi Jinping and U.S. President Barack Obama earlier this month to limit their emissions after 2020 sent a powerful signal that a global deal could be possible next year. The two countries, which produce about 40 percent of all global emissions, long have been adversaries in the U.N. climate talks.

The United States can reduce greenhouse gas emissions by 80 percent by 2050, using existing or near-commercial technologies, according to researchers with the Deep Decarbonization Pathways Project. The study analyzed scenarios with four types of decarbonized electricity: renewable energy, nuclear energy, fossil fuel with carbon capture and storage, and a mixed case. The scenarios achieved reductions of 83 percent below 2005 levels and 80 percent below 1990 levels, according to the study, which was released ahead of next month?s climate talks in Lima, Peru, and negotiations in Paris in December 2015. The energy efficiency of buildings, transportation, and industry would need to increase through the use of smart materials and energy-efficient designs, and vehicles will need to be fueled with electricity generated from wind, solar, or nuclear, as opposed to coal, the researchers said. They project the net costs would be on the order of 1 percent of gross domestic product per year. The 80-percent reduction by 2050 is a long-standing goal of the Obama administration, in line with the global commitment to limit global warming to less than 2 degrees Celsius. ?One important conclusion is that investment opportunities in clean technologies will arise during the natural rollover and replacement of infrastructure,? said lead author Jim Williams. ?The plan calls for non-disruptive, sustained infrastructure transitions that can deeply decarbonize the U.S. by 2050, and enhance its competitive position in the process.?
