According to Katharine Hayhoe in 2007, 

More frequent days with temperatures above 90F are occurring across the Northeast, and, these observed changes are consistent with those expected to be caused by global warming.

 

She must have forgotten to check Pennsylvania.

She also mentions that

Since 1970 the Northeast has been warming at a rate of nearly 0.5 degrees Fahrenheit per decade.

 

 Has nobody told her about the Atlantic Multidecadal Oscillation?

Can anyone tell Katharine what will happen to Northeast temperatures when the AMO starts to turn back downhill in the next few years?

    Paradoxically it is getting [a bit] warmer on the US east coast during a global cooling period. It just runs a bit out of phase as does London.

    Basically what happens is that as the temperature differential between the poles and equator grows larger due to the cooling from the top,there will be more clouds and rain, and snow, in these areas, causing a natural green house effect.
    Awesome, is it not?
