Actually that is not what I contend. What I contend is that the effect, by a greenhouse mechanism, of an additional 120 molecules of CO2 per million molecules of air over the period from the mid 1890s to 2014s is not detectable against a background of all the other important heating and cooling influences on the Earth. I also contend that temperature changes over the past 100 years are not abnormal.

So much for global cooling...
"Africa, July 2014
Mean temperatures were much warmer than average across Africa, with some locations across the west experiencing a record warm July."
Seriously? ..."global warming causes cooling" --- there is not enough crack on the face of the earth to alter scientific reality in this manner.
That's fucking absurd. You are either very stupid or a liar.
So you DO contend that man made CO2 is not causing warming. Thank you for confirming.
And this chart?
And don't forget, CO2 levels determine the temperature of the earth. Always has and it is doing so now. It the most important greenhouse gas the earth has. Without it the earth would be 40 degrees colder.
The temp spike is certainly abnormal and only CO2 increase explains it. There is no other reason for it.
Deniers may as well argue that cigarettes are not harmful. Oh wait, they HAVE done that. Same group of scumbags.

Fortunately, according to that homo db, warming causes cooling. So we're OK.
The few degrees of warming is nothing compared to the climate change this warming unleashes.
Remember the polar vortex, the huge mass of Arctic air that can plunge much of the U.S. into the deep freeze? You might have to get used to it.
A new study says that as the world gets warmer, parts of North America, Europe and Asia could see more frequent and stronger visits of that cold air. Researchers say that's because of shrinking ice in the seas off Russia.
Normally, the polar vortex is penned in the Arctic. But at times it escapes and wanders south, bringing with it a bit of Arctic super chill.
That can happen for several reasons, and the new study suggests that one of them occurs when ice in northern seas shrinks, leaving more water uncovered.
Normally, sea ice keeps heat energy from escaping the ocean and entering the atmosphere. When there's less ice, more energy gets into the atmosphere and weakens the jet stream, the high-altitude river of air that usually keeps Arctic air from wandering south, said study co-author Jin-Ho Yoon of the Pacific Northwest National Laboratory in Richland, Washington. So the cold air escapes instead.
That happened relatively infrequently in the 1990s, but since 2000 it has happened nearly every year, according to a study published Tuesday in the journal Nature Communications. A team of scientists from South Korea and United States found that many such cold outbreaks happened a few months after unusually low sea ice levels in the Barents and Kara seas, off Russia.
