  • The records show warm but not extreme conditions during the document’s final revision and approval, with Congress adopting the Declaration that afternoon and sending it for printing the next day.
  • Jefferson also logged 72 degrees on July 5, when copies were dispatched to committees, assemblies and Continental Army commanders, and an 80-degree peak on Aug. 2, when the Declaration was formally signed.
