Humans -ARE BY FAR- the Dominant Cause of Global Warming: A Comprehensive Review of the Science

[kpete]

Skeptical Science reviews the scientific literature, which shows humans are the dominant cause of global warming.
by Dana Nuccitelli

At Skeptical Science, we have several recent studies which have used a number of diverse approaches to tease out the contributions of various natural and human effects to global warming. Here we will review the results of these various studies, and a few others which we have not previously examined, to see what the scientific literature and data have to say about exactly what is causing global warming.

All of these studies, using a wide range of independent methods, provide multiple lines of evidence that humans are the dominant cause of global warming over the past century, and especially over the past 50 to 65 years (Figure 1).

Figure 1: Net human and natural percent contributions to the observed global surface warming over the past 50-65 years according to Tett et al. 2000 (T00, dark blue), Meehl et al. 2004 (M04, red), Stone et al. 2007 (S07, green), Lean and Rind 2008 (LR08, purple), Huber and Knutti 2011 (HK11, light blue), and Gillett et al. 2012 (G12, orange). This has been added to the SkS Climate Graphics Page.

1. In this country, there doesn't seem to be much debate about the origin of climate change.......

And I can't imagine there being much debate over the science.

Is this 'debate' another hobby horse of the religious right?

4. Um, evolution...

You're dealing with a party that still debates the merits of evolutionary science, where a sizable percentage literally believe the Earth is 6,000 years old, and God put dinosaur bones in the ground just to screw with us.

6. Oh, right. Sorry, we don't have much debate about that, either......

It's amazing to me.

9. I thought Satan threw in dinosaur bones to fool us and make us doubt the Bible.

But now a lot of believers are saying no, Jesus loved dinosaurs, sometimes cradling their young in his loving arms. People used triceratops like oxen, to plow the fields.

In any case, the science is all wrong. The bible proves it.

2. On a related note,

shit happens. And when it does, 99.9% of the time it's because humans are involved.

3. This is bigotry towards Humans

Machines are the real culprit. Machine made Machines.

5. Am I reading this graph wrong?

Humans are responsible for more than 100% of global surface warming? I thought the maximum someone could be responsible for something would be 100%.

7. The writers argue that natural events should have cooled the earth.

Therefore any warming is more than 100% caused by humans. This graph is pop science at best. It would never be allowed in any peer reviewed journal. It does not contain any range of error or where the mean or median is.

10. It's a review of science

they only acknowledge a review of their God.
