Honestly, I don't see what's so controversial about this. Science, at its roots, should be objective. At least that's my understanding of things.
That IS the exact point..
Controversy comes into the picture when lawmakers start making policy on science before the facts are all in or when they make policies that are to their advantage but detrimental to others.
The simple fact is, there just is not enough evidence to say either way.
The Earth IS getting warmer (but it's done that before).
Humans ARE pumping a lot of Carbon Dioxide (contrary to popular belief, CO2 is a "weak" contributor to "greenhouse" gases) into the air. The issue is whether or not that is having the effect we think it is. The atmospheric concentration of CO2 has approximately doubled since the start of the industrial revolution. The models we have predict a certain increase of temperature. The actual increase measured is about half that much (and not statistically different from our understanding of "natural" increase). This could mean a number of things. One, that the CO2 measurements are off. Two, that the models are wrong. Three, that temperature measurements are wrong. Four, that there are factors that lead to, at least, a partial cooling of the planet to make up for the increase. Five, that there is no human influence on planetary temperature. Or, five, that our paleoclimatic records are wrong and the planet doesn't naturally increase it's temperature as much as we think..
See? Not as simple as "Oil Companies are causing global warming to line their pockets", is it?
One of the most interesting things to come out of the talk was that Exxon-Mobil is one of the leaders in researching alternative energy sources (Fossil Fuels WILL run out eventually, no matter what, so they'd better have alternate ways to make a buck). That kinda flies in the face of the "oil companies are suppressing alternative energy" thing you usually hear..
I still haven't been able to get the presentation slides. Dr Spencer wasn't in his office when I went to see him after I got out of class. I went to the meeting, then came back to my office to get my book for Atmospheric Radiation, made the "no flying chairs" post, and went to class.. By the time I got out, he'd left the building for the day. Poo.
