Revisiting: Hurricanes are slowing down and becoming more dangerous

In 2017, Hurricane Harvey moved very slowly across parts of Texas (US) dropping “more than 30 inches of rain in two days and nearly 50 inches over four days.” “Harvey’s rainfall exceeded every known flooding event in American history since 1899.” The reason for the high rainfall totals was the slow movement of the storm–and a 2018 study (Kossin) reports that “between 1949 and 2016,…

How cities are/will be impacted by climate change

News: City life has changed and will change even more due to the impacts of climate change.
