Mark bad climate.nasa.gov redirects as 404 (#1306)

NASA went through a year-and-a-half long transition of pages from `climate.nasa.gov` to `science.nasa.gov/climate-change` that concluded a couple weeks ago. Unfortunately, when they finished, they started redirecting `climate.nasa.gov/*` to the new climate change home page instead of to the matching page on the new site, making a bunch of URLs effectively into 404s.
