Is that so?

The Union of Concerned Scientists begs to differ:

By matching the observed and modeled patterns, scientists can now positively identify the "human fingerprints" associated with the changes. The fingerprints that humans have left on Earth's climate are turning up in a diverse range of records and can be seen in the ocean, in the atmosphere, and at the surface.
...
The identification of humans as the main driver of global warming helps us understand how and why our climate is changing, and it clearly defines the problem as one that is within our power to address.
...
with aggressive emission reductions as well as flexibility in adapting to those changes we cannot avoid, we have a small window in which to avoid truly dangerous warming and provide future generations with a sustainable world.

But in case you think "scientists" are a biased interest group, the United Nations Intergovernmental Panel on Climate Change (IPCC) concludes that

we are seeing global warming caused by human activities and there are growing fears of feedbacks that will accelerate this warming.

There are literally dozens of others, but I won't bore you. You might start with the National Academy of Sciences' report to the Bush administration on this issue, which pretty much directly contradicts what you just said. The fact is, there's a broad scientific consensus on this point. Are there cranks who are producing junk science on the other side of this issue? Of course.

There are also "scientists" who believe in creationism--and there have been "scientists" who believe that the earth is flat. Now is NOT the time to stick our heads in the sand on this issue, because it's not yet too late to create meaningful change.

As it happens, I agree with some who've said that nuclear power is probably the answer, at least in the short term. That makes me a bad environmentalist, I'm told. I'm no expert--and I realize that this merely substitutes one problem for another. But warming and greenhouse gases is a much more urgent problem right now--and we need an efficient power source that can be implemented quickly.
