Scientists agree that there's man-made climate change. There's no nuance of what the implications will be (e.g. rising sea levels, failing crops, mass migration), or what the solution should be (e.g. carbon tax).
It feels insanely difficult to say "climate change is real, but it's not something we should [overly] worry about; humans are getting better at combating natural disasters, our food yields are getting better, and the best we can do for the 3rd world is [for them] to continue to use gas [for the time being]"
