Yeah there is. Good evidence.
Stupid people call it global warming, and worry about environments changing, and sea levels moving about, but these things happen all the time and are a normal part of geological history.
We may be effecting them and speeding them up, but that’s not a huge cause for concern.
The problem isn’t SUVs either. It doesn’t make a damn bit of difference what we drive here in the US.
The problem is the buildup of Carbon dioxide and other greenhouse gases in the earth’s atmosphere. Western industrialization has raised the levels of these gases appreciably and dramatically as has been verified and reverified many times.
Now, four billion or so people are living in the unindustrialized third world, and their going to want the benefits of modern society and they’re going to industrialize.
They’re not going to want to waste money on things like catalytic convertors and clean energy plants. They’re not concerned about the environment. They’re concerned about economic and physical survival.
They are going to need to burn a lot of fuel to industrialize. That fuel is likely to be coal. There are huge reserves in India and elsewhere. It is cheap, abundant and economical.
Carbon Dioxide rates are rising fast enough and accelerating even now. The industrialization of the third world is gonna make that look like peanuts.
Burning takes the oxygen out of the air and puts in carbon dioxide.
The only way that the carbon dioxide gets taken out, and oxygen put back in is from plants, trees and such.
We’re not exactly doing good things to the forests.
Anyway to make a long story short, once Co2 concentrations reach a certain level nobody breathes anymore.
In the meantime we probably get huge algae blooms that completely choke the ocean of life.
Anyway people worried about SUV emmisions are kind of missing the big picture. It’s like complaining about a small leak in the ceiling of your house right before the tidal wave hits and blasts it to smithereens.
