Hold on didn't you guys just have one of the coldest winters in decades?
Oh also they are predicting another freezing winter this year. So which is it global warming or cooling, you can't pick and choose.
In case people just don't get this, March is usually the hottest month of the year. In the northern hemisphere, this might seem kind of strange. Part of the reason for this is that the Earth is closest to the Sun in January, and furthest from the Sun in July.
Average monthly temperature from data.giss.nasa.gov...
Over the longer term, the trend is slightly different - but it's possible that could be from less accurate measurements.
The Earth's orbit is not a circle. The Earth is closest to the Sun in January. It is furthest six months later. The entire Earth receives a greater radiation during January. It receives less radiation during July.
The total amount of energy received at ground level from the sun at the zenith depends on the distance to the sun and thus on the time of year. It is about 3.3% higher than average in January and 3.3% lower in July.
In a point at the top of Earth’s atmosphere, the beam of nearly parallel incident
sunrays is referred to as extraterrestrial radiation (ETR). ETR fluctuates about
6.9 % during a year (from 1412.0 Wm-2 in January to 1321.0 Wm-2 in July) due
to the Earth’s varying distance from the Sun.

I'm very happy for you. Ever vote republican? I was a registered democrat for 25 years. Only democrat I ever voted for was Ed Koch.

The OP is refering to the US only, i guess. Because here in Europe, we've had the coolest summer in decades- it never got hot. It's like we went from spring right on into fall.
Even in the Antartic, it was the coolest summer ever recorded. wattsupwiththat.com...
If there is a global trend, it would have to be extreme weather in general- not extreme heat. It would have been less misleading if the title of the thread specified it was refering only to the US....
-but this being page 8, I imagine that has already been said repeatedly...
