My instinct tells me that we're destroying the planet. The effect of global warming is hard to see, but it's not hard to imagine given all of the other messes we've made.
Seriously, whenever money or prestige is involved, the bad science has a much better chance.
Money and prestige? Really? I wasn't aware climate science was the path to fame and wealth. Do you only trust the poor and obscure?
Phil Jones is famous and was reasonably comfortable tenured professor with a guaranteed steady income, and wielding power over most of the western world with prophecies of doom and gloom. It's unlikely he'll say "I've been wrong for the last 20 years" regardless of what science shows.
There are numerous examples: Read Michael Pollen's NYTimes "Unhappy meals", "Is it all one big fat lie" or Gary Taubes "Good Calories, Bad Calories" on how nutrition science is perverted for profit.
Read about the recent raw milk legislation about how medical science is perverted for profit.
edit: Wanted to say I'm not stating anything about climate research, as I don't know enough about it; just that I don't share the "good science outnumbers bad science" view.
