The violet filter on the Imaging Science System aboard Voyager 1 and 2Many years ago, I said to a colleague, “What a beautiful shirt! Royal blue is a good color on you.” She replied, “What do you mean blue? This shirt is purple!” After some experimenting, we discovered that we consistently differed on the line between blue and purple. In extending our experiments to co-workers, we found that I was the outlier—most people saw blue and purple more like my colleague. It turns out that such differences are real; the proteins that detect light in our eyes can be tuned to slightly different wavelengths, and we can each have slightly different ratios of the three proteins that allow us to distinguish colors. I really do see blue where most people see purple. (Do you? Here’s a Buzzfeed quiz.)

In part 1, I observed that there are two obstacles that might seem to face teachers wanting to use recent extreme weather, like Hurricane Harvey, in teaching about climate change: the complexities and uncertainties involved in attributing specific weather events to global climate change on the one hand, and the tendency of the opponents of teaching climate change to portray those complexities and uncertainties as admissions of ignorance and error.

Extreme weather events are occurring across the country and around the world. Just to name a few recent events in the U.S., 2017 has seen a record swing from drought conditions to the wettest winter in California history; the earliest tornadoes in Massachusetts and Minnesota history; hurricanes Harvey, Irma, and Maria in rapid succession; and record wildfires, again in California. Surely something is screwy, right?

The other week I got to see something really amazing: a community where teachers have all the support they need to teach climate change and evolution.

NCSEteach is a unique resource for science teachers. The monthly NCSEteach newsletter goes out to over 6,000 teachers nationwide and the Scientist in the Classroom program fosters collaborations between professional scientists and educators. This year, three teachers were awarded a rafting trip down the Grand Canyon in 2017, and shared their experience through the NCSE blog (Marie Story, Nate Chisholm, and Robyn Witty).

We are proud of our teachers, and the work they are doing!
