- Last year, researchers with the US Geological Survey (USGS) and two universities published a report that an event like the recent flood in Yellowstone was increasingly likely due to climate change.
- The report found that the average temperatures could increase by up to 10 degrees in the coming decades and the region should expect intense dry conditions peppered with dangerous downpours.

- As temperatures continue to climb, extreme events will not just increase – they’re more likely to overlap and become “compound extremes”.
- The flood in Yellowstone was a “compound extreme” after warming weather flushed melting snow into the waterways as a deluge pelted the region, dropping up to three months-worth of summer rain over the span of just a few day.
- Following the heat dome in the Pacific Northwest last year, Portland, Oregon is working on multiple projects to keep residents cool this summer.
- The TriMet bus system created a new policy that it would not collect fares from riders traveling to or from cooling shelters any time the state or county issues a heat emergency.
