RE: What's Your Favorite Climate Change Study?
What It Would Really Take to Reverse Climate Change - Funded by Google and published by IEEE. No idea who peer reviewed it.
The main weakness I see is that they hand-waved away their main conclusion with some vague talk about disruptive innovation.
Bottom line: There's no way to reverse climate change with existing or foreseeable technology. So it really doesn't matter if it's man made or natural. We should follow Google's example and stop wasting money on it. Let's all just start getting along with each other again and focus on global prosperity so that we can adapt to whatever changes come our way.
Unfortunately, most of the public debate is of a political and pseudo-religious nature, so the science doesn't really matter. Virtually no one will be persuaded - either way - by scientific arguments.
