Editing Nuclear winter (section)

=== Nuclear summer ===
A "nuclear summer" is a hypothesized scenario in which, after a nuclear winter caused by [[aerosol]]s inserted into the atmosphere that would prevent sunlight from reaching lower levels or the surface,<ref name="New Scientist">{{cite journal|journal=[[New Scientist]]|date=February 26, 1987|title=Researchers Blow Hot and Cold Over Armageddon|page=28}}</ref> has abated, a [[greenhouse effect]] then occurs due to carbon dioxide released by combustion and [[methane]] released from the [[marsh gas|decay of the organic matter]] such as corpses that froze during the nuclear winter.<ref name="New Scientist"/><ref name="Irregular Warfare">{{cite web |author=Gates |first=John M. |title=The U.S. Army and Irregular Warfare, Chapter Eleven The Continuing Problem of Conceptual Confusion |url=http://www3.wooster.edu/history/jgates/book-ch11.html |archive-url=https://web.archive.org/web/20110814051805/http://www3.wooster.edu/history/jgates/book-ch11.html |archive-date=2011-08-14 |access-date=2011-11-27}}</ref>

Another more sequential hypothetical scenario, following the settling out of most of the aerosols in 1–3 years, the cooling effect would be overcome by a heating effect from [[greenhouse warming]], which would raise surface temperatures rapidly by many degrees, enough to cause the death of much if not most of the life that had survived the cooling, much of which is more vulnerable to higher-than-normal temperatures than to lower-than-normal temperatures. The nuclear detonations would release CO<sub>2</sub> and other greenhouse gases from burning, followed by more released from the decay of dead organic matter. The detonations would also insert [[nitrogen oxide]]s into the stratosphere that would then deplete the [[ozone layer]] around the Earth.<ref name="New Scientist"/>

Other more straightforward hypothetical versions exist of the hypothesis that nuclear winter might give way to a nuclear summer. The high temperatures of the nuclear fireballs could destroy the ozone gas of the middle stratosphere.<ref name="Irregular Warfare"/>
