I think that's true although it's also true that rapidly increasing CO2 now seems a dangerous experiment with our only planet.
As an aside noting the downvotes on the above comment I sometimes question if that stuff is a good idea. I can see the point that mentioning high CO2 levels may not be a problem could be dangerous as the masses will keep burning CO2 but trying to drum up panic isn't working that great as illustrated by the "highest point in 800,000 years" thing. From an engineering kind of view point I feel you should look at things as neutrally as possible though I guess from a political view point maybe not.
