Can you identify convincing scientific evidences that human release of carbon dioxide, methane, or other green house gases is responsible for the earth's global warming effect? Is global warming really happening? What can and cannot be done about it?

What do you think about this activity?

I find it interesting that only a few years ago, there was a global cooling scare: "The coming of the next Ice Age" and other similar headlines were heralded from the newspapers. But now they have made a complete turnaround. It seems to me that Global Warming is just another fad scare and it will hopefully come out that the data that supports it is unscientific. BTW, the computer generated models (CGM's) that the UN and others use to promote this propaganda were applied to past data to see if they could predict current (observed) conditions, and they failed. If we can't trust these models to predict observable conditions, why would we trust them to predict future (unobserved) conditions? Hopefully someone will present some evidences that Humans are NOT wrecking the planet via "Global Warming" to enhance this discussion.
