But in real life, do you actually expect we will stop climate change before it causes any serious harm? When do you think we'll start doing that? We've done almost nothing so far but what we have done is incrementally developed technology to allow humans to comfortably survive severe weather like storms, floods, and droughts. So I say pragmatic because it's a continuation of what we already do, and optimistic because I believe it will be successful at saving us. I've yet to see a highly likely climate change prediction that couldn't be defended against with engineering on a scale smaller than what we've already achieved.
