Museum Lecture – August 15, 2019 – Climate Change

Since the industrial revolution, global average surface temperature has significantly increased, likely making our planet the warmest it has been in the last millennium.  This, has led the Intergovernmental Panel of Climate Change to conclude that warming of the climate  system is undeniable, and that most of the warming is very likely due to the observed increase in anthropogenic greenhouse gases.        Human caused climate change is now likely to continue for many   centuries, including not only additional warming of our planet, but  also changes in temperature extremes and precipitation, decreases in snow and ice extent, and sea level rise.  We are venturing into the  unknown with climate, and its associated impacts are likely to be quite disruptive.
