How can the climate be warming if I keep getting blizzards in my town?

The most important concept around climate change is that "weather", such as snowstorms and blizzards, is different then "climate". With climate change, the extremes are what fluctuate most: the colds are colder, and the hots are hotter. This sounds like your experience with blizzards and snowstorms. You may actually be experiencing more extreme cold weather as the planet warms due to greenhouse gases because of how the jet-stream is changing and warmer ocean temperatures put more water vapor into the atmosphere. Although it may seem that the weather is still cold at a local level, nearly every scientist agrees that climate change is causing more dramatic and extreme weather all around the world.
