The climate always does change, and always will. But our activity looks like it is pushing it in a direction that could make life very difficult for us in the long run. Increasing CO2 concentrations are melting the permafrost in the near-arctic regions, which will release even more CO2 and methane, which in turn will accelerate warming even further.
We're not in danger of becoming Venus, but in a few decades to a century we may be facing more than just rising sea levels and adverse weather; we may be dealing with large-scale drought and facing staggering population losses. We may also be causing the extinction of numerous other species during this time.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
