If observed climate variables such as temperature or precipitation change over time, it raises the question as to whether human influence plays a role. To investigate this, scientists are applying a method for estimating causal relationships.
The fact that greenhouse gases emitted by humans are changing the global climate system is scientifically undisputed. Climate researchers often look to the future with their models and try to calculate how the increasing concentration of CO2 in the atmosphere will affect various climate variables.
To test whether these climate variables are influenced by rising greenhouse gas emissions from human activities, scientists have developed the detection and attribution method.
The method involves a combined analysis of long observation series and simulation experiments in which climate models are calculated both with and without human influence in order to compare them with the actual observations. If the latter are only reproduced by the simulations with emissions, it can be concluded that man-made climate change is demonstrable in the observations.
The detection and attribution method is an important instrument for climate research and was used in the last UN climate report in the chapter on the evidence of man-made climate change.

Its really a simple math formula. Take an eye dropper of ink and squirt one drop into a swimming pool the size of 100 Olympic sized pools. No wait, that was the oil spill in the Gulf.
Never mind
The fact that greenhouse gases emitted by humans are changing the global climate system is scientifically undisputed
Just like in the 70’s when the Ice Age was here and we were all going to freeze to death, or how about Acid Rain, Allar, the Ozone hole and CFC’s and of course the $2500 reduction in Health Insurance Premiums per year, ALL GUARANTEED AND UNDISPUTED FACTS.
PUT THE PIPE DOWN UNTIL AFTER WORK, OK.
How can man-made climate change be proven?
It can’t. That is what makes it a perfect tool of the Left!
But I don't see any units on that graph. And the words below describing it seem to imply it is just a conceptual graph to get the idea across of what it would be like if the data favored the climate alarmist position...in other words fiction...but not clearly labeled as fiction...while all the actual factual graphs I have seen have it the other way.
Seems highly dishonest to me.
"The fact that greenhouse gases emitted by humans are changing the global climate system is scientifically undisputed [??? emphasis added]."
On the other hand, note that Phys.Org shows that scientists arent scared to challenge other scientific absolutes, questioning Einsteins ideas about the speed of light for example.
Theory that challenges Einstein's physics could soon be put to the test
Actually this statement is correct. The significance of the effect is in dispute though. Its like if you make a campfire you also certainly are warming the planet, but also nobody thinks the amount is significant. CO2 is a greenhouse gas and emitting some into the air will have some warming effect. But the debate at issue is whether its enough to bother about. I think the answer based on data since the early 2000s is no, its not enough to bother with. But the theory won't die because promoting it pays for the research due to the corrupting influence of politics.
Something I realized years ago was that water vapor is created by diffusion. Diffusion increases with heat. If Water Vapor was a positive feedback effect, the process would run away with itself.
Our mere existence proves conclusively that water vapor is not a positive feedback effect, but is instead a negative feedback effect.
To be more clear, water vapor is positive up to a certain amount of humidity, but when the atmosphere has soaked up enough to form clouds, the clouds reflect more sunlight back into space before it has a chance to warm the lower layers of atmosphere. This creates the negative feedback effect. More water vapor, more clouds, more sunlight reflected.
The system is self balancing, and a runaway greenhouse effect is impossible.
Outstanding presentation by a rational, highly respected Nobel Laureate. Scientific practicality-Occam’s Razor logic. With direct, correct analysis of the temperature models (and methods, the changing (!) thermometers/methods, locations and inclusion suddenly to monkey/massage the data points— the ocean temperatures). Models constructed from assumptions and ridiculously small number of comparative data points to arrive conclusively at a “fraction of a degree” average for the entire WORLD over 100 years.
Things ignored— population shrinkage worldwide, natural and man-made:
Two somethings ignored in those 100 years is what happened historically. 1) Actual loss of human life (natural and manmade losses) and 2) War which WAS clearly man made and SHOULD (accepting their assumptions on CO2) have increased the warming if you accept the notion that man’s activities to generate CO2 are directly linked vs. the actual temperature change in the “models”. Wars... lots of them, including two World Wars (worldwide, WWII more so than WWI but both involving massive use of petroleum fuels).

Who needs proof?
Oh goody!
Now their super computers can manipulate millions of terabytes of new data!
“How can man-made climate change be proven?”
Yup, start with a conclusion and try to prove it.
No science here. Move along.
They finally realize than climate change can occur without human activity, mainly because it has in the past. Not rocket science.
Didn't take long to get to a bald-faced lie.

Thank you, that was very informative.
The hallmark of all skeptical and disproveable scientific postulations is to forecast them so far in the future that no one can hold you accountable. Eventually the scientist and his predictions will be forgotten.
If the humans are removed, who or what will measure the after? Who or what will do the comparison?
That’s what they should be showing the kids in school. If I was in academia, I would make sure it happened.
The effect is completely negligible and there insignificant. No one can even prove it CO2 makes the temperature go up or down as the accepted science is all faked.
One supervacano Blows and it will put out multitudes more CO2 than every spec of pollution Man has ever created on this earth.
And they still cannot model water vapor ... clouds, rain ... the largest greenhouse gas of all. Not in their models.
