The overarching question imparting urgency to this exploration is: Can U.S.-Russian contention in cyberspace cause the two nuclear superpowers to stumble into war? In considering this question we were constantly reminded of recent comments by a prominent U.S. arms control expert: At least as dangerous as the risk of an actual cyberattack, he observed, is cyber operations’ “blurring of the line between peace and war.” Or, as Nye wrote, “in the cyber realm, the difference between a weapon and a non-weapon may come down to a single line of code, or simply the intent of a computer program’s user.”
"Fear of solar geoengineering is justified. So is fear of the largely unaccounted-for tail risks of climate change, which make the problem much worse than most realise. Ending fossil fuels will not eliminate climate risks, it just stops the increase of atmospheric carbon. That carbon and its climate risk cannot be wished away.
There is a prudent case for an international, transparent, and sustainable solar geoengineering research programme that includes field experiments with appropriate governance."
