The good news of all those climate change plans is that they actually do cut into the business-as-usual projection of greenhouse gas emissions as well as temperature, we are no longer heading to a world that would increase temperatures by 4, 5 or sometimes even 6 degrees( Celsius) according to some studies, which is what we had a few years ago. But, rather, with full implementation of these climate change plans, we could be heading to a future that would increase the global temperature by 2.7 or 3 degrees.
