The global scientific body on climate change will report soon that only greenhouse gas emissions can explain freak weather patterns.

And the situation remains fundamentally unchanged: The scientist are more concerned, the US government is more determined to not act, and the situation keeps getting worse.
Another example of Republican leadership in action.
