BIG leaf!

monster poison ivy leaf

This photo was sent by a viewer. And this might be the largest poison ivy leaf we have ever seen! Could be 6 x 8 inches, which is enormous.

Because of vastly increased CO2 in the atmosphere, poison ivy is growing larger (and more potent). 

Of course, nastier poison ivy is not the most profound result of the increase in CO2; that would be climate change. (Want to argue that? Make my day.)

When I was a kid, rarely was a poison ivy leaf larger than two inches long, but these monsters are becoming more common.

In fact, we would have wondered if this IS poison ivy, but the viewer sent many good photos that were clearly PI, and this was among them.
