There will be a global reckoning, I believe, once the results of the November 3rd election are known.  On the one hand, there won't be a simple and full "snap-back" to pre-Trump relationships if Biden wins.  But on the other hand,  if Biden wins, our European allies will be hoping for a renewed U.S. commitment to NATO, our Asian allies will let it be known that they've been holding a seat for us in the TPP, and the Paris Accord signatories would make a show of flexibiltiy -- as I suggest in the post -- about the precise mechanics/timeline of withdrawal.  In the converse case, I think the Accord would continue but there would likely be some defections by countries such as Brazil and Poland.  The critical issue would be how much the U.S. and China both would continue to backslide in the face of the COVID-19-triggered global economic slowdown and as a result of continuing deterioration of the U.S.-China relationship as Xi continues to overplay his hand and as Trump continues to try to isolate and, to a certain extent, demonize China.
