Please join us. It will be at the West Metro Critical Thinking Club on Saturday, December 28, 2013, at 10:00 AM at the RidgePointe Senior Apartments on 12600 Marion Ln. W, Minnetonka, MN.
I know these people. This will be a tough audience. This is a well educated and thoughtful group. Also, there are many climate skeptics in the group, and a talk given last September that questioned the strength of the evidence for Global Warming was well received. So, this is going to be interesting and fun!
Here’s the writeup for the talk, and more info can be found HERE:
The Global and Local Impacts of Climate Change
Anthropogenic climate change, also known as “Global Warming,” has emerged as a significant reality affecting societies and economies around the world and at home. In this talk we’ll examine the contentious questions of changes in weather patterns and sea level rise. Both of these effects of warming have already had impacts and these impacts are expected to increase in the future. What does the science say about “weather whiplash,” severe storms, and the rise of seas in the near and longer term future, how certain are we of what may happen, and how severe might these impacts be?
Greg Laden is a science communicator and teacher who has studied the relationship between human evolution and ecology, climate change during the Holocene, and African and North American prehistory. He has addressed, mostly through his writing on National Geographic Scienceblogs, the science of climate change, and has presented several talks and workshops on this issue. He is currently teaching at Century College and is writing two books, one on fieldwork in the Congo and the other, a novel, on life in the upper Midwest and Plains in a post-climate change world. He strongly hopes that the novel remains fiction rather than prediction. Greg lives with his wife and two children in Coon Rapids, Minnesota.
I’m purposefully not going to address the following things beyond a brief mention:
<ul>
Atmospheric CO2 has increased and this increase is because of the burning of fossil fuels by humans.
<li>This change in the chemistry of the atmosphere has caused the warming of the atmosphere and oceans in accord with expectations from the physical science, and continues apace.</li></ul>
These are facts so well established by science that I don’t need to drive across town to tell them to people. Within that second fact is the question of the so-called “Hiatus” and I’ll address that briefly but really, it is just a Fox News meme and need not demand the energy and time of this thoughtful group of well educated people.
Sea level, storms, and weird weather, on the other hand, are a different thing. There are aspects of this feature of climate change that climate scientists argue about among themselves, and the there are differences between what the IPCC officially said in its recently released report and what many groups of mainstream climate scientists say. The differences are not deep or huge … we are not talking about science denialism here. But there is uncertainty and we are approaching new territory. This makes the science interesting, and the potential consequences of climate change make it important.
See you on December 28th, come hell or high water. As it were.
