Not to sound like the Phelps... but maybe some of this crazy weather is God's doing for something we've done wrong as a people... look to the Old Testament...

Ezekiel 25:17,

And I will execute great vengeance upon them with furious rebukes; and they shall know that I [am] the LORD, when I shall lay my vengeance upon them

Isaiah 13:9

Behold, the day of the LORD cometh, cruel both with wrath and fierce anger, to lay the land desolate: and he shall destroy the sinners thereof out of it

Nahum 1:2

God [is] jealous, and the LORD revengeth; the LORD revengeth, and [is] furious; the LORD will take vengeance on his adversaries, and he reserveth [wrath] for his enemies.

Just as examples.
