Scientists admit that their weather models are still relatively crude. Others claim the models could be completely misleading. Thus wood, coal, gasoline and natural gas used for heating, power generation, or in automobiles and trucks all produce carbon dioxide. Each sector has been reducing emissions, using improved technologies. But we all work somewhere.
Industrial expansion is needed to keep up employment.
That means more energy consumption and GHG emissions. Europe proposes that developed countries take drastic measures to limit global temperature increase by the year 2100 to 0.9 degrees below what would otherwise occur. Two simpler ways to go Fortunately, two other developments could reduce average temperatures by half a degree without imposing substantial pain. The first will occur naturally. World oil and gas production is expected to peak in 2020 and then drop as reserves start running out.
