Too often, rising climate risk is conflated with rising CO2. That takes the heat off national and local leaders who can cut drivers of risk on the ground now. Andy Revkin collects in-depth perspective from scientists and others on the global risk of flooding, the inequities and policies that are driving up that risk, and what we can do to manage it. Revkin cites work that involved Albert Kettner and Bob Brakenridge of the DFO Flood Observatory.

Satellite imagery reveals how floods are changing and who’s most at risk. A new global floods database involved Bob Brakenridge and Albert Kettner of the DFO Flood Observatory.

Massive explosions of energy happening thousands of light-years from Earth may have left traces in our planet’s biology and geology, according to new research by CU Boulder geoscientist Robert Brakenridge. The study, published this month in the International Journal of Astrobiology, probes the impacts of supernovas, some of the most violent events in the known universe. To study those possible impacts, Brakenridge searched through the planet’s tree ring records for the fingerprints of these distant, cosmic explosions. While not conclusive, his findings suggest that relatively close supernovas could theoretically have triggered at least four disruptions to Earth’s climate over the last 40,000 years.
