This is a short article that explains a lot about the field of geoengineering. It introduces the reader to a subject they likely haven’t heard of before, and explains some pressing issues surrounding this technology. Overall, the article conveys its ideas well with the help of good organization and strong transitions.
The topic heading used in this article aren’t very specific (“Lone Rangers”) but they do inform the reader where one point of discussion ends and another one begins. “Albedo Enhancers” is about the advantages and disadvantages to one geoengineering approach, “Lone Rangers” describes the harm that just one country could cause with a geoengineering venture, and “From Science Fiction to Facts” emphasizes the need for scientific and international consensus on geoengineering matters. Tying these sections together are strong transitions that serve to orient the reader. These transitions help speed up the pace, when it is easy get caught in technical details.
One particularly strong transition appears at the very end of “Albedo Enhancers”: the author writes about potential disadvantages and disasters caused by artificially raising albedo. He (or she) then mentions that the massive consequences of geoengineering projects mean that international responsibility is needed, before moving on to “Lone Rangers” and the risks of unilateralism.
