Climate change and its impacts are both obvious and pervasive, through measurement and experience. Climate change itself is controversial in some circles, and its connections to certain extreme weather hazards are controversial even within science. The globe has warmed by nearly two degrees Fahrenheit in the last century. How much of that has been driven by human, versus natural, activity? Through September, 15 separate weather and climate disasters have caused at least one billion dollars in direct damages in the United States. How are these events related to climate change? This presentation will examine climate change, from the lens of the institution tasked to calculate both the rate of warming and the number of billion dollar disasters, and will explore the relationships between climate and extreme weather, and share insights on what can be learned from history.
