unfortunatly the best way to stop global warming is to stop burning things that make co2 and produce waste heat at the same time. you can not tell the data apart since whenever you get co2 you also get heat: in our gas heat, in our cars, in our power plants. Even when you air condition, you make more heat than you take ou of your house
the amount of BTU's lost by thermal efficiencies - range 30 to 45%- in most processes are enormous. For just oil, consider the effects of converting 50 million barrels a day of oil into heat, since a 50% conversion ratio is pretty opimistic.
so how many BTUS in a barrel of oil compared to suns daily heating? that is the number that is most important. then add wood and coal and gas. Very very big numbers, enough to affect heat of earth
We are also changing our albedo by having to make room for people and losing forests
that is why I think that fuel cells and solar power will help.
It is thought that a great degree of volcanism wih attendent burning helped usher in the last ice age.
right now NYC is 5 degrees warmer that its surroundings just because of the power used. On a global scale you dont have to think beyond whether there are more things burning today than there was 50 years ago.
The population has increased about 4 billion. that a lot of extra "fires"
