Judith Curry is a climatologist at Georgia Tech, infamous for flirting with the denier community on the basis that some of them have "good ideas" and can't get their contrarian papers published. For instance, she has posted on Anthony Watts' blog, as well as Steve McIntyre's Climate Audit. She has further embarrassed herself (and her university) by using refuted denier talking points and defending the Wegman Report, eventually admitting she hadn't even read it in the first place.[1] This and other shenanigans led Tamino of Open Mind to say, "Judith, your credibility is now below zero."[2] In short, she's the Richard Lindzen of the South. Or maybe the Roy Spencer of Georgia, take your pick. Perhaps what has sparked the most criticism, more than any other one thing, is that she has invited McIntyre to talk at Georgia Tech. No, really.[3] This makes her a massive enabler. Some other stuff she's been wrong about: Maybe the Heartland Institute isn't so bad after all![4] The BEST team tried to "hide the decline," because there has been "no warming since 1998." (This was widely quoted in a Daily Mail article.)[5] (From the same Daily Mail article) "The models are broken." She later backed down about this on her blog, saying she was misquoted and "had no idea where it came from."[6] Murry Salby is right about CO2 and every other scientist is wrong.[7] This list could actually go on for much longer -- just go to her blog for more info.
In addition, the IMF has also come to the same conclusion... Carbon Pricing: Good for You, Good for the Planet Posted on September 17, 2014 by iMFdirect By Ian Parry The time has come to end hand wringing on climate strategy, particularly controlling carbon dioxide (CO2) emissions. We need an approach that builds on national self-interest and spurs a race to the top in low-carbon energy solutions. Our findings here at the IMF—that carbon pricing is practical, raises revenue that permits tax reductions in other areas, and is often in countries’ own interests—should strike a chord at the United Nations Climate Summit in New York next week. Let me explain how. http://blog-imfdirect.imf.org/2014/09/17/carbon-pricing-good-for-you-good-for-the-planet/
Don't laugh bro, these guys are going to become the new terrorists. They're becoming increasingly shrill and increasingly irrational. The whole movement has completely broken away from the scientific method and are beginning to resemble the Flagellants. http://en.wikipedia.org/wiki/Flagellant Prediction: The climate change cult will commit large scale eco-terror before the decade is out.
They already have. Years ago I remember some of these moon bats setting SUV's on fire. Sending thick plumes of toxic smoke into the very air they were supposedly protecting by burning the gas guzzlers to begin with.
The effect of adding man-made CO2 is predicted in the theory of greenhouse gases. This theory was first proposed by Swedish scientist Svante Arrhenius in 1896, based on earlier work by Fourier and Tyndall. Many scientist have refined the theory in the last century. Nearly all have reached the same conclusion: if we increase the amount of greenhouse gases in the atmosphere, the Earth will warm up. What they don’t agree on is by how much. This issue is called ‘climate sensitivity’, the amount the temperatures will increase if CO2 is doubled from pre-industrial levels. Climate models have predicted the least temperature rise would be on average 1.65°C (2.97°F) , but upper estimates vary a lot, averaging 5.2°C (9.36°F). Current best estimates are for a rise of around 3°C (5.4°F), with a likely maximum of 4.5°C (8.1°F). What Goes Down… The greenhouse effect works like this: Energy arrives from the sun in the form of visible light and ultraviolet radiation. The Earth then emits some of this energy as infrared radiation.Greenhouse gases in the atmosphere 'capture' some of this heat, then re-emit it in all directions - including back to the Earth's surface. Through this process, CO2 and other greenhouse gases keep the Earth’s surface 33°Celsius (59.4°F) warmer than it would be without them. We have added 42% more CO2, and temperatures have gone up. There should be some evidence that links CO2 to the temperature rise. So far, the average global temperature has gone up by about 0.8 degrees C (1.4°F): "According to an ongoing temperature analysis conducted by scientists atNASA’s Goddard Institute for Space Studies (GISS)…the average global temperature on Earth has increased by about 0.8°Celsius (1.4°Fahrenheit) since 1880. Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15-0.20°C per decade." The temperatures are going up, just like the theory predicted. But where’s the connection with CO2, or other greenhouse gases like methane, ozone or nitrous oxide? The connection can be found in the spectrum of greenhouse radiation. Using high-resolution FTIR spectroscopy, we can measure the exact wavelengths of long-wave (infrared) radiation reaching the ground. Figure 1: Spectrum of the greenhouse radiation measured at the surface. Greenhouse effect from water vapour is filtered out, showing the contributions of other greenhouse gases (Evans 2006). Sure enough, we can see that CO2 is adding considerable warming, along with ozone (O3) and methane (CH4). This is called surface radiative forcing, and the measurements are part of the empirical evidence that CO2 is causing the warming. ...Must Go Up How long has CO2 been contributing to increased warming? According to NASA, “Two-thirds of the warming has occurred since 1975”. Is there a reliable way to identify CO2’s influence on temperatures over that period? There is: we can measure the wavelengths of long-wave radiation leaving the Earth (upward radiation). Satellites have recorded the Earth's outbound radiation. We can examine the spectrum of upward long-wave radiation in 1970 and 1997 to see if there are changes. Figure 2: Change in spectrum from 1970 to 1996 due to trace gases. 'Brightness temperature' indicates equivalent blackbody temperature (Harries 2001). This time, we see that during the period when temperatures increased the most, emissions of upward radiation have decreased through radiative trapping at exactly the same wavenumbers as they increased for downward radiation. The same greenhouse gases are identified: CO2, methane, ozone etc. The Empirical Evidence As temperatures started to rise, scientists became more and more interested in the cause. Many theories were proposed. All save one have fallen by the wayside, discarded for lack of evidence. One theory alone has stood the test of time, strengthened by experiments. We know CO2 absorbs and re-emits longwave radiation (Tyndall). The theory ofgreenhouse gases predicts that if we increase the proportion of greenhouse gases, more warming will occur (Arrhenius). Scientists have measured the influence of CO2 on both incoming solar energy and outgoing long-wave radiation. Less longwave radiation is escaping to space at the specific wavelengths of greenhouse gases. Increased longwave radiation is measured at the surface of the Earth at the same wavelengths. These data provide empirical evidence for the predicted effect of CO2 http://www.skepticalscience.co...reenhouse-effect.htm
