According to experts, the risk of nuclear war is currently very high. This applies in particular to the risk of accidental nuclear war. Climate change will significantly increase this risk in the coming years or decades. Increasing capacities for cyber wars and a new arms race with hypersonic missiles also increase the risk of nuclear war. These correlations (also between climate change and nuclear war risk) are described in www.unintended-nuclear-war.eu/ (see in particular the section entitled ” unintended nuclear war – quick introduction to the topic”).
Even with a locally limited nuclear war (e.g. between India and Pakistan), there is a great danger of a nuclear winter with a drop in temperature and food production worldwide being ruined. (see https://www.pik-potsdam.de/aktuelles/nachrichten/regionaler-atomkrieg-waere-ein-risiko-fuer-die-globale-ernaehrungssicherheit, http://news.ippnw.de/index.php?id=1700 and https://www.zeit.de/2018/08/atomkrieg-ruestungsindustrie-atomwaffen-usa-russland, page 2)
An “unintended nuclear war” is thus followed by a “nuclear climate change” in the form of an “accidental ice age”.
