The Greenhouse Effect and its impact on Earth's surface temperature have been understood for over a century. Long before satellites, computer models or even computers existed, scientists recognized that the massive increase in fossil fuel combustion beginning with the Industrial Revolution would lead to a warming planet and a changing climate. This lecture reviews the evolution of climate change science from the early 1800s to the present, profiling 12 scientists—from Joseph Fourier to Klaus Hasselmann. Key scientific issues will be discussed in the context of these historical figures and their contributions to our understanding of climate change. In addition, the impacts of climate change on humankind and the measures that need to be taken to mitigate it will be discussed.

This lecture takes place virtually via Zoom.
