"...as I often say, weather is your mood and climate is your personality. So on any given day, you can have really cold weather or really violent weather. But the scientific literature, including our recent AMS Climate Change statement, does suggest that our climate is changing and I think we can say some things about certain weather phenomenon and climate phenomenon that are more linked to this climate change and we are in a different climate system now. Almost every weather phenomenon happens in a warmer and more moist climate."
