I teach physics. The most depressing part of my job is teaching a general-education class where I have to explain global warming.
Scientists don't have a private agenda. We would LOVE to be wrong about this, but:
- Temperatures are going up worldwide
- Global temperatures are historically very well correlated to CO2 concentrations
- CO2 concentrations have a straightforward and well-understood effect on infrared light produced by
earth's blackbody radiation
- Even small changes to global temperature will create big changes to local climates
- We can stop this, but only if radical action is taken right now
so
- We're all fucked.
This is not the time for the debate about whether the effect is real. This is the time for debate about just how MUCH we should be panicking. We're in the deep shit here. We're talking about large proportions of humanity not having enough food to eat. The resulting warfare and hardship will be devastating.
