agreeof course, certainly things like solar activity has been increasing over the last century, yet other contributors, such as sulfur, have actually been decreasing
How does the increase in Solar activity affect our climate? We don't know.
How does the increase in CO2 affect our climate? We don't know.
We've become so entrenched in it must be greenhouse gases, that we are no longer looking to WHY it's happening.
We've never bothered to prove the hypothesis that Greenhouse gases are the cause of Global Warming.
The Earth warms and cools naturally, but this is unprecedented (certainly, since the 60s) and warming has been going hand in hand with increased emissions
It's also been going hand in hand with increased sun spot activity...
It's also been going hand in hand with decreased cosmic ray activity...
We don't know what's causing it... picking a topic and acting as if that's the answer, without actually PROVING IT, is about as idiotic as deciding the transmission is the problem with your car, and repeatedly tearing it apart unable to make the car work (problem could be the engine or alternator... etc...)
even if the amount of human contribution was as low as 30% (and its a lot higher as you know), why would we not take action?
We don't know how much we affect the climate AT ALL. It could be as low as 5%.
If CO2 plays an important part in cloud formation, than the amount of CO2 in the atmosphere doesn't matter one bit. We don't know that either.
If you graph the amount of cosmic ray activity, and the amount of cloud cover, there appears to be a relationship between the two.
Good cloud cover can completely offset every bit of greenhouse gases in the atmosphere. That's why volcanoes (which emit more greenhouse gases in one eruption than man has throughout our entire history) don't affect the climate. The Haze created by an eruption cools the earth in spite of the greenhouse gases put into the atmosphere.
