The climate is always changing regardless of man's influence or not. Although, man's influence is not just theoretically accelerating this change, it is basically accelerating the change. Just because it is not a "proven" fact doesn't discredit the concerns or it's existence. There is more than enough evidence suggesting it's existence even if not a completely proven fact. As an example, some people say smoking is not a proven fact that will lead to cancer. Yes this is actually true, but you can't take away the fact that there is more than enough evidence suggesting that smoking can increase the risk of cancer.
Just "one" of the major concerns that faces "Climate change" aka "Global Warming" is the accelerating rise of the ocean. Eventually at the rate the ocean is rising because of things like the "polar icecaps" melting alone due to this "climate changing" The current entire Mid Atlantic Seaboard will basically just become another part of the Atlantic Ocean sooner than later.

As a side note weather changing and climate changing are two different things when talking about "global warming". Just because you live somewhere and are experiencing extremely cold weather other places in the world are most likely experiencing extremely warm weather.
