NEW YORK (TheStreet) -- The on-again, off-again debate over global warming is on again.While fighting global warming has become a $1 billion a day industry, according to the Global Warming Policy Initiative, that's less than half what should be going into mitigating climate change, and even less than what's being spent subsidizing fossil fuels. The World Bank has weighed in with a report called On Thin Ice: How Cutting Pollution Can Slow Warming and Save Lives. The report says better stoves for the developing world, better control of methane and improved efficiency for diesel engines to reduce black carbon can slow melting of the "cryosphere," the glaciers and ice caps that moderate the global climate. our only hope for preventing a climate catastrophe . Meanwhile, climate skeptics have latched on to a study by Judith Curry of Georgia Tech, arguing that most scientists have underestimated the impact of natural cycles on global temperature and that the planet is actually 1 degree centigrade cooler than most models say it should be. "practical levers" to tackle the problem, such as reducing deforestation, emissions that come from agriculture and use of such chemicals as hydrofluorocarbons, which are often produced in just a few industries. It would seem that climate change has ceased to be strictly a scientific dispute, and has now become an economic one. Every side of the energy industry is now fighting for a fairly fixed investment pie and using the latest scientific studies to buttress its case.
