Pheasant population down 50% from last year

Higher temperatures are killing Pheasant's and the hunting industry in Kansas.  How?
1) Adults (along with other wildlife) are decimated in some localities.
2) High temps and drought stress chicks, few survive.
3) A warm winter and spring moved wheat harvest 3 weeks earlier than it has ever been before, robbing young birds of critical shade and shelter.

This is what global warming looks like.  Spring in some areas looks like fall.
