A Quote by Alexander Cockburn
There is still zero empirical evidence that anthropogenic production of CO2 is making any measurable contribution to the world's present warming trend.

I am not at all convinced that human emissions of CO2 are adding to global warming.... I remain to be convinced about the theory of anthropogenic global warming.
Evidence of warming is not evidence that the cause is anthropogenic.
There is a movement of more people recognizing global warming as a danger, recognizing the human contribution to global warming, recognizing the necessity for doing something about it. So there's a trend in that direction, and that trend is consistent with what a climate swerve - which is, as we're both saying, a mindset.
It's likely that CO2 has some warming effect, but real proof of that hypothesis is tricky. You have to confirm by observation exactly how the CO2 changes the situation at different altitudes in the atmosphere and in different regions of the world. For example, CO2 is supposed to warm the upper air faster than the surface, but the measurements don't show that happening. When the CO2 effect is eventually pinned down, it will probably turn out to be weaker and much less worrisome than predicted by the global warming theorists.
CO2 is a minor player in the total system, and human CO2 emissions are insignificant compared to total natural greenhouse gas emissions. Therefore, lowering human CO2 emissions will have no measurable effect on climate, and continued CO2 emissions will have little or no effect on future temperature....While controlling CO2 emissions from burning fossil fuels may have some beneficial effects on air quality, it will have no measurable effect on climate, but great detrimental effects on the economy and our standard of living.
NASA should be at the forefront in the collection of scientific evidence and debunking the current hysteria over human-caused, or Anthropogenic Global Warming (AGW). Unfortunately, it is becoming just another agency caught up in the politics of global warming, or worse, politicized science.
There is no strong evidence to prove significant human influence on climate on a global basis. The global cooling trend from 1940 to 1970 is inconsistent with models based on anthropogenic carbon dioxide emissions. There is no reliable evidence to support that the 20th century was the warmest in the last 1000 years.
The best scientific evidence suggests temperatures are rising, and the best scientific evidence suggests man-made anthropogenic carbon emissions have some substantial thing to do with that. However, does that mean the trend will continue forever? We don't know.
Actually, he gave false evidence [of chemical weapons]. In this case,[John] Kerry didn't even present any evidence. He talked "we have evidence" and he didn't present anything. Not yet, nothing so far ; not a single shred of evidence.
There's zero evidence, empirical or anecdotal, that more guns leads to less gun crime.
... The reality is that atmospheric CO2 has a minimal impact on greenhouse gases and world temperature. Water vapor is responsible for 95 percent of the greenhouse effect. CO2 contributes just 3.6 percent, with human activity responsible for only 3.2 percent of that. That is why some studies claim CO2 levels are largely irrelevant to global warming.
The truth is that the phenomena of artistic production are still so obscure, so baffling, we are still so far from an accurate scientific and psychological knowledge of their genesis or meaning, that we are forced to accept them as empirical facts; and empirical and non-explanatory names are the names that suit them best.
Industrial production of meat makes a huge contribution to global warming.
To date, no convincing evidence for AGW (anthropogenic global warming) has been discovered. And recent global climate behavior is not consistent with AGW model predictions.
It presents a really compelling case against the whole theory of anthropogenic global warming. From my point of view, it is a theory that has completely corrupted public policy making in most of the developed world. It confronts all the dubious claims that the warmists have put out there.
They've been changing the cry from "global warming" to "climate change" because there's so little evidence there's actually any warming going on. I believe that as little as a decade from now, global warming will be recognized as one of the greatest swindles in world history. It has so little scientific basis, it can only rationally be considered a political scam.
