According to a White House summary, “the report finds that, on the whole, summers are longer and hotter, with longer periods of extended heat. Wildfires start earlier in the spring and continue later into the fall. Rain comes down in heavier downpours. People are experiencing changes in the length and severity of seasonal allergies. And climate disruptions to water resources and agriculture have been increasing.”
The report is detailed, data-driven, and the online version is media-rich. In my opinion, the web-site is over-complicated and it uses a great deal of white text on blue background or thin light blue on white background… initially pleasing but not good for sustained engagement.
I suggest downloading the overview PDF (20 pages, 4.93 MB) and starting there. Reports on individual states are also available.
There are alternative views. Writing at Fox News, Mario Lewis offers, “the new report is an alarmist document designed to scare people and build political support for unpopular policies such as carbon taxes, cap-and-trade, and EPA regulatory mandates.”
There is a section of the report on Response Strategies. I cannot recommend the website for accessing this information. You can download five separate PDFs here, scroll down.
