USGS topographic maps from National Geographic

Coventry, CT - USGS 7.5 minute quad National Geographic has made available nearly all of the topographic quadrangle maps from the US Geological Survey as PDF download.

They are pre-packaged using the standard 7.5 minute, 1:24,000 base but with some twists:

  • Page 1 is an overview map showing the Quad in context
  • Pages 2 through 5 are the standard USGS Quads cut in quarters to fit on standard printers
  • Hillshading has been added to each page of the PDF to help visualize the topography

I use regularly use a GPS when I’m in unfamiliar territory, but it is even better to have a topographic map to refer to. I’m delighted to have found this resource.

Climate change neoskepticism

Paul Stern and colleagues1 use the term “neoskepticism” to describe the view that although climate change is real and although humans are responsible for much of it, the costs of attempting to reduce or mitigate it exceed the benefits.

[N]eoskepticism accepts the existence of [anthropogenic climate change] but advocates against urgent mitigation efforts on various grounds, such as that climate models run “too hot” or are too uncertain to justify anything other than “no-regrets” policies as having net benefits. Mainstream climate scientists are well aware of uncertainty in climate projections. But neoskeptics’ citing of it to justify policy inaction marks a shift of focus in climate debates from the existence of ACC to its import and to response options.

The problem, of course, is that uncertainty is a double-edged sword. It’s possible that the impacts of climate change won’t be as bad as current (mean) projections, but it’s also possible that they will be far worse. Worse yet, the longer we wait to mitigate impacts, the more difficult and expensive it will be to prevent them. In response, they argue both for more attention to decision sciences and to the science of science communication. Both are certainly needed. But they also focus only on part of the science communication that’s needed, the part having to do with facts about costs, benefits, and risks of action or inaction.

As scientists, we pay too little attention to the emotional aspects of persuasion involved in guiding public policy, and here I’m not talking about appeals to “your children and grandchildren” or “our fellow creatures.” I’m talking about the emotions people feel when they think about scientists in particular or experts more generally, for example. Science communication is important even when it isn’t imparting facts or knowledge. In fact, it may be even more important when it’s not imparting facts or knowledge. It may be most important when it’s sharing scientists as caring human beings who can be trusted. Only if we are trusted will anyone listen when we share our insights with them.
