Donald Trump does not believe or support climate change and does not plan to support action or policies that support climate change. He was very vocal during the campaign that he has no intentions of supporting climate change. He will do little to create policies for sustainable development and will over ride or eliminate the policies currently in place.
Trump has openly stated that he does not believe in climate change. He has hired people who openly fight environmental protections. Trump doesn't give a hoot about our environment, and is very likely to ruin any and all progress that has been made in the last eight years. The issue is not a priority for him.
No, Donald Trump will not roll back all the progress we've made on climate change. It would be too much work to repeal all the laws that have been passed and the efforts that have been made so far. He may not allow for much headway to be made in the beginning, but there is too much evidence of the problem to be ignored for long. Soon, everyone will have to acknowledge the problem and make efforts to change it as quickly as possible.
He might not be progressing on climate change but I don't think he is going to roll back our progress. There are measures in place and checks and balances that will prevent him from doing too much damage. Faith in the system is what will make or break all the things we're worried about.
