Sobering news from Bo Nordell and Bruno Gervet of Sweden. They "have calculated the total energy emissions from the start of the industrial revolution in the 1880s to the modern day."
"They point out that net heat emissions between the industrial revolution circa 1880 and the modern era at 2000 correspond to almost three quarters of the accumulated heat, i.e., global warming, during that period."
"using the increase in average global air temperature as a measure of global warming is an inadequate measure of climate change"
Net heat emissions blows carbon sequestration and nuclear energy out of the water as solutions to global warming. We can't use so-called clean coal. We have to stop using fossil fuel all together. Because, whether it takes 100 years or 1000 years to burn it all, the net heat released will overheat the planet and make it uninhabitable.
It's like a choice between boiling ourselves alive over low heat or high heat; our only sustainable choice is to turn off that heat.
"Although nuclear power does not produce carbon dioxide emissions in the same way as burning fossil fuels it does produce heat emissions equivalent to three times the energy of the electricity it generates and so contributes to global warming significantly, Nordell adds."
Realizing that net heat emissions is the real problem means there will never be a long-term solution using fusion or fission power. To prevent civilization collapse, we'll have to redesign to depend entirely on renewables such as solar power, wind, tides, and geothermal ... methods that merely redistribute the earth's heat instead of increasing it absolutely. It also becomes clear that overpopulation is a REAL limiting factor, not merely a technological challenge.http://www.sciencedaily.com/releases/2009/07/090713085248.htm
Aagh!
