One of the major consequences of climate change is that range limits are moving north. At present, we can clearly see that the moose is gaining territory at the expense of the woodland caribou. The moose is moving north. So is the black bear. So certain species are moving in a significant way. Diseases then follow the wildlife, also in a significant way. You just have to think about Lyme disease. The ticks that carry the disease came from the United States and have moved north.
Climate change brings with it other changes too. In the spring, the snow geese are arriving more quickly in the south of Quebec and are staying longer. That causes problems for farmers. These are examples of the effects of climate change, as we see them. That is why they concern us. However, perhaps there are other positive benefits we can attribute to some kinds of climate change. For example, we now have a spring hunting season for greater snow geese, which we did not have a few years ago.
