Let's face it. We do not have a good understanding of the earth's weather system in spite of the fact that many atmospheric scientists have been trying to understand it for many years. That's why we keep sending instruments to Mars to measure it's atmospheric properties. It's a much simpler system than earth's and if we can figure out Mars, maybe it will help us figure out earth. But, we can't even figure out the Martian atmosphere!

That being said, anything that effects our atmosphere is critical to our future existance. So, when most scientists think global warming is occurring and we're at least part of the cause, we'd better pay attention.
