So you're implying that industrial conglomerates have smaller vested interests than climatologists, to whom the benefits of 'winning' are far less tangible?
It's much easier to continue with old established ways than come up with and adapt to new ones. So maybe the fact that industrial conglomerates don't really try to counter these scientists is because what the latter say is, by and large, true, and not because they are winning in some sort of a deceitful political game? I just don't see how and why the industrial conglomerates would surrender if this is merely a battle of propaganda.
The industrial conglomerates "surrendered" because they realized they can continue to pump as much CO2 as they want as long as they pay lip service to "Green" causes and preferably donate some millions to GW research.
The oil companies are a good example, as ainwood mentioned. Instead of trying to fund skeptics, as they did in the past, they now pretend to be devoted to fighting GW and even donate to warming alarmists. But have they fundamentally changed their ways? Of course not. It makes for great TV adds, though, and if they can score some publicity points and avoid a bitter fight with the environmentalist lobby all by "admitting that there is a problem" and donating a few millions of bucks every year, why not?
Again, I am not saying there is a GW conspiracy. I don't believe in conspiracies that big. I do believe in personal interest, though, and it is obvious that nowadays many of the leading climatologists make a living, and guarantee their research funds, with highly alarmist literature aimed at shocking the public and government (and thus making them more likely to open their pockets). They do have an interest of keeping the skeptics away from the "mainstream", as widespread skepticism could compromise their funding and even their careers.
I also do believe that AGW is real, we do have evidence to reasonably assume so. But can we effectively measure how significant it will be over the next decades? NO!. Can we decently estimate the economic impact of the warming, and whether the net result will be positive or negative? NO!. The IPCC should admit at least as much if it wants credibility.
