The “smoking gun” is the fossil fuel signature of atmospheric CO2 molecules.
Thinking about Carl Sagan’s “baloney buster” piece, I came across this article in The New York Times written by a geologist/journalist. She did a wonderful job of baloney busting by clearly highlighting all the scientific evidence showing that climate change is real and that this assessment has strong consensus among climate scientists. They see the data as incontrovertible. These data include: 150 years of global temperature measurements, satellite data from the 1970s, tree-ring samples, ice-core and earth samples, sea-level rise measurements, flora and fauna monitoring, and atmospheric and oceanic analyses–all pointing to the same conclusion–that it is getting hotter and we are the major contributors.
The “smoking gun” is the fossil fuel signature of atmospheric CO2 molecules. “Fossil fuels are too ancient to have any carbon-14 left in them, so if they were behind rising CO2 levels, you would expect the amount of carbon-14 in the atmosphere to drop, which is exactly what the data show.”

I'm a retired medical sociologist from the University of Rochester. Climate change is one of the two great challenges facing humanity (the other is nuclear weapons). In writing about the impact of climate change I read reputable books and articles on the topic. So when I make statements about climate change you will see a link taking you to the scientific source(s) of the information I provide.
As for my independently published photobooks, each has gone through several layers of editing and peer review for both readability and accuracy.
This is not to say that everything I say is accurate. Even the New York Times makes mistakes. So, if you find something that is factually incorrect, let me know.
I hope you find reading my blog a positive experience. If you do, please encourage your family and friends to have a look.

Best wishes,
