One could also say the folllowing:
1) Let's keep in mind that these are the e-mails from one university, and that the national science academies of virtually every nation on the planet have signed on to man made climate change, based on thousands of studies from across the planet.
That could also hiding the truth.
2) What's to say that all of the e-mails are authentic?
What's to say they are not?
3) If what this one university has found "proves" man-made climate change is bogus, why didn't anybody else twig on to it? If they did, then that would imply a truly global conspiracy, hello tin foil hatters.
Because it would be more beneficial to hide the truth? Global Conspiracy? The world has the US as the main cause of "climate change" why wouldn't they have a global conspiracy against us? It would be the smart thing to do.
-Regardless- of whether or not the increased amounts of greenhouse gases are from human activity or not, the continual increase of these gases spells a world of hurt not just for us but the entire planet.
And that's the trick right there. You also need to keep in mind that opposition to man-made climate change is not about not wanting to give up our SUV's and big screen TV's, it's about making major changes that will cost the average person too much, that will require more taxes in a short amount of time, that will make one industry fall and leave millions without jobs, etc. Basically, the changes will be big, too fast, costly and will do more harm to our society than good for something that may not stop climate change in the end.
Most people are all for cars that produce less or no emmisions, but we don't want to pay twice as much for it. Most people would rather use solar power, but the tech is still in it's early stages. Most people would rather eat healthy, but we don't want to be told what we can and can't eat. Most people woul change their electronics for more energy efficient ones, we just don't want to be limited to what we can buy, pay up the yingyang for it and also be taxed for all of it.
If we are saving the world, why does someone have to benefit financially from it in the process?
