The source I gave is not up to date....Exxon's final acknowledged contribution to the Heartland Institute was more than 22 million by 2014.
Heartland is not a research organization. They are a political think tank, which like all such think tanks attempt to influence the political landscape according to their ideology. There are many such organizations, they happen to be the largest with a vested interest in shaping the minds of people in contrast to climate science. Many of it's same people argued against the Surgeon General's warning of the dangers of smoking on the behalf of the tobacco companies. Experts in both smoking and global warming...the same people mind you.
It must be easy to use the same paintbrush for all things, but not all things are apple to apple comparisons.
Tobacco is a single source recreational product, with minimal actual benefit, and considerable bad side effects.
The fuel and other products from fossil oil, are the basis for our entire modern society.
We currently cannot support our population without the benefits of fossil fuels.
Will that change in the future? it has to, fossil oil, is a finite supply.
The when and why it will change, will be because the alternatives are the lowest cost path,
without government intervention, (roughly $90 a barrel oil).
I know you are down on Exxon, but ask yourself, what does Exxon sell?
The thing that they exchange money for, is not oil, but finished fuel products.
Their profits come from passing a raw material through a manufacturing process to produce
usable fuel for sale. Instability in the price and availability of that raw material (oil),
is the source of great business risk and expense.
Why would a large corporation expose themselves to this level of risk?
It is simply the current least cost path to profits, but it will not always be so.
Within the next decade or two, oil prices will come up, and when the profits for the
refineries to make their own feedstock exceed the profits for using crude oil, they will switch.
