The main change in climate is the global warming, and it will likely influence our future through:
-less severe winters in many regions (this is what I am experiencing) - can be seen as positive
-more severe summers with heat waves - which can be hazardous for health and which will require extra costs in form of air conditioning.
Climate is connected to the hydrological cycle, and some of the changes are:
-droughts in some regions, which mean that we have to save water and plan for the droughts
-floods in other regions, which means that those regions have to be abandoned or protected by infrustucture
