This
guideline does not mean that climate change is harmless below 2 C, or that it suddenly becomes so catastrophic above 2 C that further efforts at limiting warming are pointless, but like a highway speed limit, it serves as a
useful benchmark for where you start to worry about things being
really bad.
This is a
useful reminder that, even now after the Supreme Court has clarified in Gall and Kimbrough that the federal
guidelines are
really, truly, yes - we -
really - mean - it advisory, lots of sentencing judges are still going to be following the
guidelines advice.
