3 Questions Worth Answering in the Wake of Winter Storm Grayson

Yesterday in Massachusetts we were asking ourselves questions that have rarely, if ever, needed asking.

What happens when half-frozen seawater suddenly floods onto roadways? Can something the consistency of a milkshake and 3 feet deep be plowed? There’s a large dumpster floating down the street… What depth of water is sufficient to do that? What happens if some of this water freezes in place before it retreats (as I write this, the temps have plummeted to 12 degrees F and dropping)?

We’ve witnessed the destruction done by Hurricane Harvey and now, less than two weeks later, with clean-up in Texas and Louisiana scarcely underway, we see the path of Caribbean devastation Hurricane Irma is leaving as it heads toward mainland US. The NHC is warning that Irma will bring dangerous storm surge to coastal Florida, and heavy rain and life-threatening flooding from Florida to North Carolina.

With preparedness efforts being marshalled to the Southeast US and specific risks coming into better focus, we offer a composite of what our team – experts at the intersection of science, policy, and social equity – is seeing.

How Does Your Whiteness Inform Your Climate Work? Fair Question.

This past weekend, I had the honor and challenge of presenting at the Fifth Annual Climate Conference of the Historically Black Colleges and Universities (HBCUs). For the past three years, UCS has been proud to be one of the sponsors of this summit at Dillard University, in New Orleans, and we’re looking forward to continuing to support it in years to come.

For me personally, this year’s event took an important turn when a Howard University student stood up and posed a good, hard question: How does your whiteness inform your work on climate change? Read more >
