Climate attribution scientists using “fingerprint studies” are now able to detect man-made climate change. Not so long ago, this kind of analysis would have been impossible but climate scientists are now able to separate out the natural from the man-made influence.
Cities face downgrades from credit rating agencies if they are not deemed resilient to climate change. They are also increasingly being taken to court for a lack of preparedness. Some cities are suing the largest oil producers. Attribution science is behind these court cases.
Simon Fowell and I have an article about attribution science in the May 2018 issue of the APWA Reporter, (The APWA Reporter is the official magazine of the American Public Works Association). You can view it online here (pp. 69-72).
