No single weather event can be attributed to climate change. Storms, floods and droughts have always happened and some of them have always been severe. However, two centuries of people burning fossil fuels has altered temperatures just enough that some of the storms we have seen in recent times have been much worse than they otherwise would have been.
Plants and animals have evolved over time to live in specific environmental niches. As the climate warms, parts of the ranges in which they live may no longer offer the conditions under which they can thrive. Species can respond to these changes in three ways: they can adapt to new conditions by undergoing niche shifts; they can relocate to better conditions, such as by moving to higher elevations or latitudes; or they can locally go extinct.
