The quote above is from the 2014 federal report, Climate Change Impacts in the United States, Southeastern Region. Given the title and the subject, one would have to conclude that our government is telling us that this is a result of climate change.
“Authoritative” documents such as this often wind up in legal proceedings, as the “science” backup for proposed regulations. As such, statements of this ilk should be based upon some semblance of reality.
We find that many of these “factuals” are indeed subject to test. The one above is yet another assertion that climate change, presumably caused by emissions of carbon dioxide, is the cause of an increase in the frequency or severity of “extreme” events.
Floods and droughts qualify. After all, a flood is merely a cases of extreme high streamflow, and a prolonged drought will result an extreme low. Further, it is hard to find any weather extreme, any hurricane, tornado or wildfire where some apparent authority finds a television camera and does not blame it on global warming.
