Well it being winter in the northern hemisphere does help to explain the general cold weather there. As being summer here helps to explain the general hot weather we are experiencing presently.

'Exceptional' heatwave challenges records
Australia's “exceptional” heatwave has produced record-breaking temperatures, with at least six of the first seven days of 2013 among the top 20 hottest days in the past century. ..
Such a result would make it six days in a row when the national average has been above 39 degrees; tomorrow is expected to make it seven. Prior to this series, the longest run of 39 degrees or more was four days, in 1973. ..
The final four months of 2012 were the hottest on record for Australia and January is making an early run at adding to the sequence of especially hot weather.
“Australia-wide, and for individual states, we are currently well above average by many degrees,” said Aaron Coutts-Smith, the bureau's NSW manager for climate services.
Jeff Masters
It's been a summer like no other in the history of Australia, where a sprawling heat wave of historical proportions is entering its second week. Monday, January 7, was the hottest day in Australian history, averaged over the entire country, according to the Australian Bureau of Meteorology. The high temperature averaged over Australia was 105°F (40.3°C), eclipsing the previous record of 104°F (40.2°C) set on 21 December 1972. Never before in 103 years of record keeping has a heat wave this intense, wide-spread, and long-lasting affected Australia. The nation's average high temperature exceeded 102°F (39°C) for five consecutive days January 2 - 6, 2013--the first time that has happened since record keeping began in 1910. Monday's temperatures extended that string by another day, to six. To put this remarkable streak in perspective, the previous record of four consecutive days with a national average high temperature in excess of 102°F (39°C) has occurred once only (1973), and only two other years have had three such days in a row--1972 and 2002
Get used to record-breaking heat: bureau
‘The current heatwave – in terms of its duration, its intensity and its extent – is now unprecedented in our records,’’ the Bureau of Meteorology’s manager of climate monitoring and prediction, David Jones, said.
‘‘Clearly, the climate system is responding to the background warming trend. Everything that happens in the climate system now is taking place on a planet which is a degree hotter than it used to be.’’
As the warming trend increases over coming years, record-breaking heat will become more and more common, Dr Jones said.

Global warming has STALLED since 1998: Met Office admits Earth's temperature is rising slower than first thought
Now a press release, published yesterday, has confirmed that over the next five years temperatures will be 0.43 degrees above the 1971-2000 average, instead of the previously forecast 0.54 degrees – a 20 per cent reduction.
This rise would be only slightly higher than the 0.4-degree rise recorded in 1998, an increase which is itself attributed by forecasters to an exceptional weather phenomenon.
With all but 0.03 degrees of the increase having occurred by 1998, the revision means that no further significant increases to the planet’s temperature are expected over the next few years.

State of the Climate, National Overview Annual 2012, National Oceanic and Atmospheric Administration
In 2012, the contiguous United States (CONUS) average annual temperature of 55.3°F was 3.3°F above the 20th century average, and was the warmest year in the 1895-2012 period of record for the nation. The 2012 annual temperature was 1.0°F warmer than the previous record warm year of 1998. Since 1895, the CONUS has observed a long-term temperature increase of about 0.13°F per decade. Precipitation averaged across the CONUS in 2012 was 26.57 inches, which is 2.57 inches below the 20th century average. Precipitation totals in 2012 ranked as the 15th driest year on record. Over the 118-year period of record, precipitation across the CONUS has increased at a rate of about 0.16 inch per decade.

Solar Variability and Terrestrial Climate
science.nasa.gov
Jan. 8, 2013: In the galactic scheme of things, the Sun is a remarkably constant star. While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our own sun varies a measly 0.1% over the course of the 11-year solar cycle.
There is, however, a dawning realization among researchers that even these apparently tiny variations can have a significant effect on terrestrial climate. A new report issued by the National Research Council (NRC), "The Effects of Solar Variability on Earth's Climate," lays out some of the surprisingly complex ways that solar activity can make itself felt on our planet.

A new report issued by the National Research Council (NRC), "The Effects of Solar Variability on Earth's Climate," lays out some of the surprisingly complex ways that solar activity can make itself felt on our planet.
Many of the mechanisms proposed at the workshop had a Rube Goldberg-like quality. They relied on multi-step interactions between multiple layers of atmosphere and ocean, some relying on chemistry to get their work done, others leaning on thermodynamics or fluid physics. But just because something is complicated doesn't mean it's not real.
In recent years, researchers have considered the possibility that the sun plays a role in global warming. After all, the sun is the main source of heat for our planet. The NRC report suggests, however, that the influence of solar variability is more regional than global. The Pacific region is only one example.
Caspar Amman of NCAR noted in the report that "When Earth's radiative balance is altered, as in the case of a change in solar cycle forcing, not all locations are affected equally. The equatorial central Pacific is generally cooler, the runoff from rivers in Peru is reduced, and drier conditions affect the western USA."
Raymond Bradley of UMass, who has studied historical records of solar activity imprinted by radioisotopes in tree rings and ice cores, says that regional rainfall seems to be more affected than temperature. "If there is indeed a solar effect on climate, it is manifested by changes in general circulation rather than in a direct temperature signal." This fits in with the conclusion of the IPCC and previous NRC reports that solar variability is NOT the cause of global warming over the last 50 years.

Yep, you definitely continue to cherry pick and distort.
I mean if you had simply refrained from saying "definitely" and "significant" you could have made a point.
Understanding the sun-climate connection requires a breadth of expertise in fields such as plasma physics, solar activity, atmospheric chemistry and fluid dynamics, energetic particle physics, and even terrestrial history. No single researcher has the full range of knowledge required to solve the problem. To make progress, the NRC had to assemble dozens of experts from many fields at a single workshop. The report summarizes their combined efforts to frame the problem in a truly multi-disciplinary context.

Koch-Funded Study Finds 2.5°F Warming Of Land Since 1750 Is Manmade, ‘Solar Forcing Does Not Appear To Contribute’
By Joe Romm on Jan 20, 2013 at 12:17 pm
The Berkeley Earth Surface Temperature Study (BEST) has finally published its findings on the cause of recent global warming. This Koch-funded reanalysis of millions of temperature observations from around the world, “A New Estimate of the Average Earth Surface Land Temperature Spanning 1753 to 2011,” concludes:
… solar forcing does not appear to contribute to the observed global warming of the past 250 years; the entire change can be modeled by a sum of volcanism and a single anthropogenic [human-made] proxy.
The decadal land surface temperature from BEST average (black line), “compared to a linear combination of volcanic sulfate emissions (responsible for the short dips) and the natural logarithm of CO2 (responsible for the gradual rise) shown in red. Inclusion of a proxy for solar activity did not significantly improve the fit. The grey area is the 95% confidence interval.”
You may recall that back in July, Richard Muller, BEST’s Founder and Scientific Director, published a NY Times op-ed, “The Conversion of a Climate-Change Skeptic,” which concluded
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.
The finding itself is “dog bites man” (see It’s “Extremely Likely That at Least 74% of Observed Warming Since 1950″ Was Manmade; It’s Highly Likely All of It Was).
What makes this “man bites dog” is that Muller has been a skeptic of climate science, and the single biggest funder of this study is the “Charles G. Koch Charitable Foundation ($150,000).” The Kochs are the leading funder of climate disinformation in the world!
Muller further explained:
Our results show that the average temperature of the earth’s land has risen by two and a half degrees Fahrenheit over the past 250 years, including an increase of one and a half degrees over the most recent 50 years. Moreover, it appears likely that essentially all of this increase results from the human emission of greenhouse gases.
These findings are stronger than those of the Intergovernmental Panel on Climate Change, the United Nations group that defines the scientific and diplomatic consensus on global warming.
In short, a Koch-funded study has found that the IPCC “consensus” underestimated both the rate of surface warming and how much could be attributed to human emissions!
The Koch-finded study also finds, “the rate of warming we observe is broadly consistent with the IPCC estimates of 2-4.5°C warming (for land plus oceans) at doubled CO2.” A summary of BEST’s findings are on their website.

Richard Muller is marketing natural gas in a “converted skeptic” costume
RICHARD MULLER: Well, The Koch Foundation provided about one quarter or maybe it was one-sixth of our funding and they made it clear to us that the reason they funded us was that we did recognize that these issues were real, issues that Michael Mann did not accept as real. But, I think he was wrong. I think there were valid questions and we addressed them, and they’ve expressed nothing but delight that we have been able to reach a conclusion. So, I think this cartoon-like characterization of the Koch Foundation as being right-wing deniers, I found that to be completely wrong.
Global warming convert's natural-gas sales push
Professor Richard Muller's U-turn on global warming made headlines, but was it a publicity stunt to push natural gas?
by brainpanhandler » Tue Jan 22, 2013 12:36 pm
AMY GOODMAN: We turn now to a story making headlines in the science world. One of the country’s most prominent global warming skeptics has openly admitted he was wrong. Over the weekend, Richard Muller, a professor of physics at the University of California, Berkeley, wrote an op-ed for the New York Times titled "The Conversion of a Climate-Change Skeptic."
Dr. Muller began the piece by writing, quote, "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."
Richard Muller’s admission has gained additional attention because some of his research has been funded by Charles Koch of the Koch brothers, the right-wing billionaires known for funding climate skeptic groups like the Heartland Institute. Richard Muller is the author of the newly published book, Energy for Future Presidents: The Science Behind the Headlines.
Welcome to Democracy Now!, Professor Muller. Talk about your change.
RICHARD MULLER: Well, I felt there were legitimate issues that had not been addressed. There’s the whole issue of climate change and whether hurricanes are increasing and so on, but the most solid evidence was the temperature data, and questions had been raised. The stations that were used were of poor quality. Could that be addressed? Could you use such data? There were issues that prior groups had highly selected the data—in the U.K., using only 5 to 7 percent of the data, here in the U.S., only 20 percent of the stations. It was a concern whether they had picked stations that showed warming and not the others. There were other issues, too, about the influence of urban heat islands. Cities get warmer, but that’s not the greenhouse effect. So, is that—how do we estimate the greenhouse effect? And there was the data adjustment and then the huge computer programs that they used to make the attribution to humans. All of these things deeply concerned me, and I could not get the answers in a satisfactory way.
As a scientist, on such an important issue, I felt it was my duty to be what I would call properly skeptical. And the only way to answer this was to put together a program. So, we gathered together a group of truly eminent scientists, so people who are really good at analyzing data. These include Art Rosenfeld, who’s a hero in the energy conservation field, and Saul Perlmutter, who actually last December, after working on our project for a year, over a year, was awarded the Nobel Prize in Physics, not for work he was doing for us but for prior work he had done in astrophysics.
So, it began to come together about a year ago. We were able to show that the poor station quality, although it affected the temperature measurements, didn’t affect the temperature changes. We were able to use 100 percent of the data, not the 20 percent that others had used. We found that data selection bias didn’t affect things. We looked at the urban heat island. It came together. We concluded that global warming was indeed real.
But then, about three to six months ago, thanks largely to the effort of a brilliant young scientist named Robert Rohde, who we hired to do and use the best possible statistics in order to be able to use all the data, he was able to push our record back to 1753. That’s before the American Revolution. That’s back when the measurements in the U.S. were being made by Benjamin Franklin and Thomas Jefferson. With that long record, we could look for the fingerprints. We could see how much was due to volcanoes, how much was due to ocean currents, how much was due to the variability of the sun. We could do this much better than people had done before.
And I’ve got to admit, I was shocked when I saw the results. There was short-time—short-term variability that was due to volcanoes, essentially nothing due to the solar variation. Theoretically, that’s not too surprising, but I was surprised nonetheless. But the remaining curve, the rise in that curve, was dead on to human production of carbon dioxide and other greenhouse gases. At that point, the data had led me to a conclusion I would not have expected a few years earlier.
AMY GOODMAN: And what has been the response of your colleagues, those who, like you, have been skeptical for so long?
RICHARD MULLER: Well, I don’t expect people to say, "Oh, Muller has changed his mind, therefore I do." What we’ve done is, I think, an exceptional level of transparency. We have five detailed scientific papers, which we have placed online. These have all been submitted to peer-reviewed journals. We have put all of the data online. We’ve put all of our computer programs online, along with a lot of supplemental information that your watchers and listeners might like. If you go to berkeleyearth.org, you’ll find—you can look up the temperature record in your hometown or your home state. But by putting this online, we have a transparency where people who think we did something wrong can find, well, this is your assumption right on this line here, this is what we don’t like. And our responses is, OK, change it, see if it makes a difference, or we can change it for you and see if it makes a difference. So, this is, I think—the wonderful thing about science is that it’s that narrow realm of knowledge on which we expect to achieve universal agreement.
I believe that some of the—most of the skeptics—there were some deniers who refuse to pay any attention to the science, but many of the skeptics recognized there were valid problems with the data. And we have now directly addressed those. So my hope is that as they study our work, that they will recognize that we did address these in the proper way, and that now the—now we can agree on the science. How you address this, what you do on the international arena, is a separate question.
AMY GOODMAN: I want to ask you about the role of Congress in the climate debate, Dr. Muller. On Wednesday, the Senate held its first hearing on the topic in more than two years. The Republican-controlled House has turned down 15 requests from Democrats for a similar hearing. Senator Barbara Boxer, of course Democrat of California, your state, who chairs the Environment and Public Works Committee, opened the session.
SEN. BARBARA BOXER: Colleagues, climate change is real. Human activities are the primary cause, and the warming planet poses a significant risk to people and the environment. I believe to declare otherwise is putting the American people in direct danger. The body of evidence is overwhelming. The world’s leading scientists agree, and predictions of climate change impacts are coming true before our eyes. The purpose of this hearing is to share with the committee the mountain of scientific evidence that has increased substantially over time—time that I believe we should have used to reduce carbon pollution, the main cause of climate change.
AMY GOODMAN: Most of scientists who testified said human activity has accelerated climate change, intensified a recent U.S. heat wave, and raised sea levels. But much of the hearing was dominated by senators bickering over the science. Senator James Inhofe of Oklahoma, the ranking Republican on the committee, echoed points from his recent book, The Greatest Hoax: How the Global Warming Conspiracy Threatens Your Future. His points were disputed by independent Senator Bernie Sanders of Vermont.
SEN. BERNIE SANDERS: Now, Senator—Senator Inhofe has said repeatedly, recently just the other day on the floor of the Senate and in his book, which I am reading—I am reading it. He gave it to me very kindly, and I’m going to read every word of it. He said that, in his view, global warming is the greatest hoax ever perpetrated on the American people. Now, my understanding is that NOAA says global average surface temperatures have increased 1.3 degree Fahrenheit since 1900. NASA says the global average surface temperatures of this planet have increased by 1.5 degrees Fahrenheit since 1880. Dr. Richard Muller recently wrote an article in which he said that the planet has warmed 2.5 degrees Fahrenheit over the last 250 years. So, either NASA, NOAA and many other scientists are correct in stating that the planet is warming, or perhaps Senator Inhofe is correct that global warming is a hoax.
AMY GOODMAN: That’s independent Senator Bernie Sanders. Professor Muller, your response?
RICHARD MULLER: Well, I’m hoping that our study on global warming will help achieve the sort of scientific consensus. I understand why many of the skeptics in Congress have opposed—have opposed it in the past. I’ve been there, I’ve talked to them in the past, and they had raised issues which were ones that I considered value—correct, issues that now I think we have raised. You know, just because global warming is real doesn’t mean that everything attributed to it is real. Hurricane Katrina was not caused by global warming. Polar bears are not dying because of global warming. A heat spell in France—even the recent record year of temperatures in the United States is not a result of global warming, because if you look at the complete detail, you’d find it was matched by more than cooling elsewhere in the world. So, many people attribute every change in the weather to global warming, and I can understand why people object to that. But the temperature change itself is real, and it is due to humans. And I think, because I now feel that this is true, and I think we could make the scientific case more solidly than had been made in the past, I think this does say we do need to take action, and we do need to do something about it.
AMY GOODMAN: What is your message, particularly to Republican lawmakers like Senator Inhofe? And were you consulting with them before your conversion?
RICHARD MULLER: Oh, yes, I’ve met with both the Republicans and the Democrats and explained things to them. I’ve been asked to come several times to Washington, D.C. The message, however, is not an easy one, and I find nobody really likes my message, neither the Republicans nor the Democrats.
My new message is there are two things that must be done if we’re going to stop this. There are many things you can do. We each can do our part. You know, we can get higher-mileage automobiles and all that kind of stuff. But from the world point of view, there are only two big things that can be done. One of them is an extensive program in energy conservation and energy efficiency. This is absolutely essential, and there are huge gains to be made. The fact is, energy efficiency and conservation are profitable. And that’s really important, because, unfortunately, most of the global warming, most of the carbon dioxide, is going to be coming not from the U.S. but from China. Anything we do must be something that can be emulated and followed in China. Electric cars, for example, don’t do any good. If a Chinese person switched from a gasoline car to an electric car, he would wind up producing more carbon dioxide, because that electricity is coming from coal, and that’s worse than gasoline. So, we have to do things that will have an impact.
The other thing we need to do is—and this is one where, unfortunately, a lot of my Democrat friends have a knee-jerk reaction against it, but I think it’s essential—we have to get the Chinese to convert, to move over, get away from coal into a natural gas economy. By the end of this year, China will be producing twice the carbon dioxide of the United States, and whereas our carbon dioxide is going down, their carbon dioxide is shooting up. So it will get worse and worse. Natural gas produces only one-third of the carbon dioxide that does coal. And the coal chokes their citizens, too. Now, in the U.S., a lot of people say, "Oh, fracking is bad. It’s dirty," which is true, "and it’s a fossil fuel." Well, China can’t afford—will not be able to afford massive solar and massive wind for several decades. In the meantime, soon they’ll be producing more carbon dioxide per person than we are. So, we have to help them, expedite them switch over to natural gas, that has one-third of the emissions of carbon dioxide. Anything we do in the U.S., if we ignore China, is not really addressing the problem.
AMY GOODMAN: When Democracy Now! was at the U.N. Climate Change Conference in Durban this past December, I spoke with Marc Morano, publisher of Climate Depot, a website run by climate denier group Committee for a Constructive Tomorrow, and I asked him about President Obama’s record on climate change.
MARC MORANO: His nickname is "George W. Obama." Obama’s negotiator, Todd Stern, will be here today. They have kept the exact same principles and negotiating stance as President George Bush did for eight years. Obama has carried on Bush’s legacy. So, as skeptics, we tip our hat to President Obama in helping crush and continue to defeat the United Nations process. Obama has been a great friend of global warming skeptics at these conferences. Obama has problems, you know, for us, because he’s going through the EPA regulatory process, which is a grave threat. But in terms of this, President Obama could not have turned out better when it came to his lack of interest in the congressional climate bill and his lack of interest in the United Nations Kyoto Protocol. So, a job well done for President Obama.
AMY GOODMAN: That’s Marc Morano, publisher of Climate Depot, run by the website—the climate denier group Committee for a Constructive Tomorrow. Dr. Muller, your response?
RICHARD MULLER: Well, I think that in opposing any—joining the Kyoto agreement, President Obama recognized that the non-involvement of China made our participation—would not have done much. At Copenhagen, President Obama went there to try to get the Chinese involved. He insisted on having inspections, because the Chinese rate of growth, they’ve averaged 10 percent growth over the last 20 years. That growth is so enormous that they are going to dominate the global warming—global warming of the future. And if they wouldn’t even allow us to inspect, then we can’t do—if we were, in the United States, to cut back to zero—ridiculous, but let’s say we cut back to zero emissions—within three-and-a-half to four years, the emissions would be back where they were just from the growth of China. So I think President Obama has done the right thing in insisting that China must be involved.
In the proposed Copenhagen treaty, they were going to slow their growth to 6 percent per year rather than cut it to zero. And even at that, they would be surpassing us. So I think he’s done the right thing. Now, what we need to do, I believe, is to—we need a presidential program, a national program, in which we will share our technology. No, we don’t want dirty fracking in China any more than we want it here, but we can make it clean. It’s just a matter of using the technology to assure that it will be clean, that it won’t cause earthquakes and so on. That, as a technical problem, is not that difficult. We need to share our technology with them to help them switch away from coal, which is what is going to be responsible for the global warming of the future.
AMY GOODMAN: Richard Muller, you’re known for your change of heart on climate science, your "conversion," as you’ve described it, and it’s come fairly recently. I want to play a comment you made during a 2009 interview.
RICHARD MULLER: One, you have to recognize how bad it is. And the surprising answer is that so far it hasn’t been very bad. We’ve had about one degree Fahrenheit of global warming so far, none whatsoever in the last 10 years. You need to know that, because otherwise you will misunderstand. When people criticize global warming and say it’s not real, the reason they’re saying it’s not real is there hasn’t been any in 10 years. But we don’t expect it to happen every year. It’s a gradual thing that builds up.
AMY GOODMAN: Professor Muller, that was you speaking in 2009. Is this still your opinion?
RICHARD MULLER: Oh, yes. In fact, my former book, Physics for Future Presidents, goes through Vice President Al Gore’s movie, An Inconvenient Truth, and I think correctly shows that essentially 90 percent of what he presented was exaggerated or distorted or just false. But I think part of the problem here is that when we attribute every change in the weather to climate change, we engender a lot of skepticism. And that, I think, in the end, has done some harm. I think science has hurt itself by exaggerating the case.
Global warming, so far, has not been very much. In the last 50 years, it’s been two-thirds of a degree Celsius, over—well, one degree Fahrenheit, and that hasn’t been much. One-third of the cities in the United States have cooled over the last 100 years. Astonishing statistic, but not surprising when you realize that local variations are much larger than this one-degree change. The danger isn’t that we have done harm. The danger is that we understand that this will continue to go up, that in the future, what is now two-thirds of a degree will become one, two, three degrees, and that that will be warmer than Homo sapiens have ever experienced.
So, I believe we need to act, but we need to act in a way that recognizes the problem isn’t with us, the problem is with the world, particularly with the extensive coal that is used around the world, in the developing countries. If we don’t address that, then we are just playing games. We’re going to say, "Oh, hey, we—you know, I have an electric—I have a Prius. Hey, I’m not to blame. I did my part." No, that’s baloney. We need to address the real problem, which is the extensive coal burning, and we have to bite the bullet and recognize that natural gas is the only thing that can get us there over the next 20 years, that and energy conservation. Energy conservation is win-win. I believe the Chinese will adopt that. We should help them adopt that, because that is something where they can earn money at a great return, better than Bernie Madoff, but it’s legitimate. You can—again, my new book discusses in detail the many places where you can get a profit of 20 percent, 30 percent per year just by investing in energy conservation. So that combination of energy conservation, on one hand, and then the switch to the natural gas economy via clean fracking, on the other hand, I think can get us through to the era when China and India can afford solar and the upcoming technologies that will finally get us away from fossil fuels.
AMY GOODMAN: Finally, Professor Muller, I wanted to get your response to Michael E. Mann, the director of the Earth System Science Center at Pennsylvania State University, who wrote on his Facebook page, "There is a certain ironic satisfaction in seeing a study funded by the Koch Brothers—the greatest funders of climate change denial and disinformation on the planet—demonstrate what scientists have known with some degree of confidence for nearly two decades: that the globe is indeed warming, and that this warming can only be explained by human-caused increases in greenhouse gas concentrations. I applaud Muller and his colleagues for acting as any good scientists would, following where their analyses led them, without regard for the possible political repercussions." Your response to Michael Mann and to your Koch-funded research and what this means for them?
RICHARD MULLER: Well, the Koch Foundation provided about one-quarter, or maybe it was one-sixth, one-sixth of our funding, and they made it clear to us that why, the reason they funded us, was because we did recognize that these issues were real, issues that Michael Mann didn’t accept as real, but I think he was wrong. I think there were valid questions, and we addressed them, and they’ve expressed nothing but delight that we have been able to reach a conclusion. So I think this cartoon-like characterization of the Koch Foundation as being right-wing deniers, I found that to be completely wrong.
Michael Mann, on the other hand, has published a lot of things that I disagree with. He has claimed that there was no—that there was no Medieval warm period, that it’s been the warmest now it’s been in a thousand years. And I was a part of that National Academy study that basically demonstrated that his conclusions were wrong. So, no, he and I don’t agree on lots of things.
But I think now the key thing is, science is that small realm of knowledge on which there can be universal agreement. And so, now I’m hoping we will have that universal agreement, that—it’s not going to happen overnight. People will read our papers and study them, and I hope that the open-minded skeptics will be won over. I also hope some of the climate exaggerators, who blame Hurricane Katrina on global warming, will also come and meet everybody halfway and say, "OK, we were exaggerating. Global warming is real. We need to do something about it. This is the science. And now we recognize that the solutions must be energy conservation."
AMY GOODMAN: But, Professor Muller, your fundamental conversion—your fundamental conversion is that climate change is largely human-caused.
RICHARD MULLER: I wouldn’t put it as "climate change." I would say "global warming." Too many things in climate change are actually just weather or local climate. So, I can go through a list of them, but I would not say all climate change—
AMY GOODMAN: But global warming—no, we just have 10 seconds.
RICHARD MULLER: Just global warming, yes. Global warming is human-caused.
AMY GOODMAN: Well, I thank you very much.
RICHARD MULLER: You’re welcome.
AMY GOODMAN: Richard Muller, professor of physics at the University of California, Berkeley. His op-ed piece, "The Conversion of a Climate Change Skeptic." I thank you very much for being with us.

And I’ve got to admit, I was shocked when I saw the results. There was short-time—short-term variability that was due to volcanoes, essentially nothing due to the solar variation. Theoretically, that’s not too surprising, but I was surprised nonetheless. But the remaining curve, the rise in that curve, was dead on to human production of carbon dioxide and other greenhouse gases.
