"have to be a century-long transition to energy sources that have no impact on the climate" A century long???What part of systems theory, energy interactions, and stagnant energy science is still not understood? What part of freedom inextricably interwoven with evolution, survival, wisdom, understanding and quality of life is still NOT understood on the energy front?

Climate Panel Reaches Consensus on the Need to Reduce Harmful Emissions
By ANDREW C. REVKIN and SETH MYDANS
BANGKOK, May 4 — The world’s established and emerging powers will need to divert substantially from today’s main energy sources within a few decades, to limit centuries of rising temperatures and seas driven by the buildup of heat-trapping emissions in the air, the top body studying climate change has concluded.
In an all-night session capping four days of talks, economists, scientists, and government officials from more than 100 countries agreed in Bangkok early today on the last sections of a report outlining ways to limit such emissions, led by carbon dioxide, an unavoidable byproduct of burning coal and oil.
The final report, from the Intergovernmental Panel on Climate Change, said prompt slowing of emissions could set the stage later in the century for stabilization of the concentration of carbon dioxide. Now at about 380 parts per million, the concentration has risen by more than one-third since the start of the industrial revolution, and could easily double from pre-industrial level within decades.
The report concluded that significant progress could be made toward halting the increase in the next 25 years using known technologies and policy changes, setting the stage for what would have to be a century-long transition to energy sources that have no impact on the climate.
Several authors said its message was clear.
