Climate change is just what it sounds like: a change in climate. Weather will trend to extremes. Storms will be more severe, droughts will be more extreme, cold temps will be colder, warm temps will be warmer, etc. You get the idea. It is not a made up concept, it is for real. It has continually become more severe since the Industrial Revolution. The burning of fossil fuels! Will the Earth be able to survive? Probably, but not without severe consequences:world wide hunger and poverty, displacement, and the extinction of many animal and plant species. Is climate change something to worry about? YES!
