Then we should be afraid [Social Darwinism]. Very afraid. [Eugenics]
Yesterday Creationists confused the science of Evolution with the political application of Evolution to public policy (Social Darwinism, & Eugenics). They were wrong. Politics never disprove science; only evidence can do that.
Today "skeptics" of climate change tell us that the science of climate change is wrong because of the possible irresponsible political applications of climate science to public policy. They too are wrong. Politics never disprove science; only evidence can do that.
" If Darwin's theory had come from a computer model and it turned out his computer model didn't match real world observations, nobody would believe it."
That is your opinion, but I prefer facts.
"UN climate change projections made in 1990 'coming true'
Climate change projections made over two decades ago have stood the test of time, according to a report published Monday in the journal Nature."

The people who have actually compared the model projections to observed climate changes over the past two decades have found the models to be accurate.
We are not a clone.
