Richard A. Muller said:Just as important, our record is long enough that we could search for the fingerprint of solar variability, based on the historical record of sunspots. That fingerprint is absent. Although the I.P.C.C. allowed for the possibility that variations in sunlight could have ended the "Little Ice Age," a period of cooling from the 14th century to about 1850, our data argues strongly that the temperature rise of the past 250 years cannot be attributed to solar changes.

Richard A. Muller said:To be considered seriously, an alternative explanation must match the data at least as well as carbon dioxide does.
So the suns activity level has no effect on the temperature on earth?Just as important, our record is long enough that we could search for the fingerprint of solar variability, based on the historical record of sunspots. That fingerprint is absent
Over the last 50 years or so, Earth's average temperature has, by some accounts, risen about one degree Fahrenheit. During this same time, global warming has been observed on Mars, Neptune, Neptune's moon Triton, and Pluto. Is that just coincidence or are natural cycles at work?
That's right AGW is pure bureaucratic science, whose end goal is more control and less freedom.I offer for your consideration an essay by British scientist and engineer Dr. John Brignell titled: "How we know they know they are lying." Among other things, he discusses the difference between real science and bureaucratic science (BS):
Lovey80 said:YKY, I think you'll also find there was excessive temperatures but the temperature rises significantly PRECEEDED the spikes in CO2 by a significant time frame. Something the liar himself Al Gore chose to manipulate so that it looked the other way round.
I'm not trying to bust your balls YKY we are in the same camp almost. Just making sure that the basis for that is correct.

You're a bit behind the times there Yippee.

Er...

It would seem that the actual data indicates the exact opposite of what you're saying.

Yippe-Ki-Ya said:I'm loathe to have to break this to you - but much of the so-called "land surface records" of temperature are not worth much mate. Artificially high temperatures have been recorded due to their proximity to built up "manmade/artificial" areas and stuctures.
By far the best measurement of whether the planet is heating of cooling is the temperature of the oceans - especially the deep parts.
And so sad for you, but ocean temperature analysis does show that the planet is in a cooling phase.

The heat island effect is addressed by the Berkeley study.
Please read it, lest you continue to appear uninformed and foolish.
Lovey80 said:Big A.D. What method did the Berkely study use to calculate it's temperature levels Pre the area of modern recording methods?
Lovey80 said:I think the people that actually compiled the Berkely study have already been made to look foolish. They have zero cred.

Edit: and that critique seems to come from a believer.
Richard A. Muller said:Call me a converted skeptic. Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming. Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I'm now going a step further: Humans are almost entirely the cause.
Lovey80 said:So, does the Berkely study show global warming is a problem or not?
Richard A. Muller said:What about the future? As carbon dioxide emissions increase, the temperature should continue to rise. I expect the rate of warming to proceed at a steady pace, about one and a half degrees over land in the next 50 years, less if the oceans are included. But if China continues its rapid economic growth (it has averaged 10 percent per year over the last 20 years) and its vast use of coal (it typically adds one new gigawatt per month), then that same warming could take place in less than 20 years.
Science is that narrow realm of knowledge that, in principle, is universally accepted. I embarked on this analysis to answer questions that, to my mind, had not been answered. I hope that the Berkeley Earth analysis will help settle the scientific debate regarding global warming and its human causes. Then comes the difficult part: agreeing across the political and diplomatic spectrum about what can and should be done.
"If Al Gore reaches more people and convinces the world that global warming is real, even if he does it through exaggeration and distortion - which he does, but he's very effective at it - then let him fly any plane he wants." - Richard Muller, 2008
"There is a consensus that global warming is real. ...it's going to get much, much worse." - Richard Muller, 2008
"Let me be clear. My own reading of the literature and study of paleoclimate suggests strongly that carbon dioxide from burning of fossil fuels will prove to be the greatest pollutant of human history. It is likely to have severe and detrimental effects on global climate." - Richard Muller, 2003
