Beer/smelly brew

Question
So I decided to put a small space heater into the closet where some of my brews were fermenting last week.  The temp changed from 65 to 70 after a few days.  Now when I go to check the progress, 2 of the 4 batches in that closet smell really strong, almost astringent nose burning strong.  What happened? Can I salvage the beers?  

Answer
Seems a little strange that the temp change would cause your problem.

Could it be that the "nose burning" is just concentrated carbon dioxide?  It doesn't smell, but it sure can get your nose's attention.

Give your brews time and don't toss anything until the end of fermentation and a tasting.
