A lot of T2k campaigns tend to relegate most macro-level game universe stuff to the background. PCs generally have a fairly narrow view of the world, as day-to-day survival is usually the most pressing concern. Regardless of whether or not your T2kU features global or large-region level environmental collapse, local environmental conditions can still affect the PCs' daily existence. In some ways, the local environment can act as an NPC, creating problems and, less frequently, opportunities, for PC parties. How has the environment factored into your gaming experience?

I ran a Pirates of the Vistula PbP for close to a decade. It's seems weird to me now, but I don't remember ever considering throwing a flooding event at my players (although I do recall describing the aftermath of past floods).

In T2k campaign set in 2030 Arkansas, the party was a unit of the State Guard sent to reestablish contact with state gov't outposts after a major hurricane, the PCs encountered a variety of storm-related damage.

I briefly ran a PbP set in New Mexico. It didn't last long enough for the environment to play any role, but I did intend for drought to affect the rural farming communities that the PCs were sent to assist.

Also the 4e core rules have a couple of environment-based random encounters- one involves a forest fire (I can't remember if it's natural, man-made, or cause-unspecified), and another a radioactive ash-fall.
