"That's just stupid. BTW where is the evidence nights are warmer? And why does the heat only come out at night?more hot days. "
No, that's what is stupid. "Why would the heat only come out at night?" is so twoish.
All this was predicted, even B4 Arrhenius wrote his theory. Just click on the studies
Global warming has a distinct greenhouse signatureAs far back as the mid 1800s, Tyndall predicted that greenhouse warming should cause nights to warm faster than days. This is because at night, the Earth’s surface cools by radiating heat out to space. Greenhouse gases trap some of this heat, slowing the night-time cooling. It took over 130 years before Tyndall’s prediction was confirmed. Over the last few decades, surface measurements have observed nights warming faster than days ( Braganza 2004, Alexander 2006, Zhou 2009).
Tyndall made another prediction of what greenhouse warming should look like. Just as greenhouse gases slow down nighttime cooling, they also slow down winter cooling. So Tyndall anticipated winters warming faster than summers. Again, recent analysis of temperature trends over the last few decades bear this out ( Braganza et al 2003, Braganza et al 2004). Both thermometers and satellites find winters warming faster than summers.

Winters Are Getting WarmerPublished: Jan 27th, 2016
By Climate Central
As the world continues to warm from the increase of greenhouse gases, the amount of extreme cold during winter will start to decrease. According to a 2013 report by Climate Central, nationwide nighttime winter temperatures since 1970 have risen about 30 percent faster than nighttime temperatures over the entire year. Every NOAA climate division has shown warming, with the Upper Midwest, Great Lakes, and New England warming the most over the past 45 years.
