Although it is true that climate change, heating and cooling cycles, have occurred throughout geologic time; the current increase in temperatures, which might have been occurring naturally, albeit much slower, are being exacerbated by excess CO2 in the atmosphere. While we destroy plant life which could moderate the excess CO2 we add to the gasses through excess fossil fuel consumption. If Trump takes us backward the gains of the past few years will be lost. However, renewables are becoming more cost effective so perhaps there is a chance that the market will actually benefit us going forward.
