Who says manmade CO2 causes catastrophic global warming?
We enjoyed the letter to the Wall Street Journal last week from 16 scientists who said there’s “no need to panic about global warming,” and of course it drew a response from a warming faction of scientists saying essentially, “yes there is.”

Adding some perspective to this they-said/they-said back and forth is yet another letter we saw today from Martin Hertzberg, a Stanford Ph. D., Stanford, class of 1959, who served as a research and forecasting meteorologist in the Navy, “long before the ersatz field now called ‘Climate Science’ was fabricated out of thin air for the main purpose of promoting the false theory that human CO2 emission was causing ‘global warming/climate change/extreme weather phenomena’,” as he put it.

The position of the warmists is: “…the science is clear: The world is heating up and humans are primarily responsible.”

The position of the other guys is: “The lack of warming for more than a decade—indeed, the smaller-than-predicted warming over the 22 years since the U.N.’s Intergovernmental Panel on Climate Change (IPCC) began issuing projections—suggests that computer models have greatly exaggerated how much warming additional CO2 can cause.”

And now comes Dr. Hertzberg, who says: “Weather and Climate are controlled by natural laws on a scale that is enormous compared to the scale of human activity. Those natural laws engender forces and motions in the Earth’s atmosphere, its oceans, and its surface that are beyond human control. Weather and climate existed long before humans appeared on Earth, and they will continue to exist in the same way long after we are gone, either individually or collectively as the human race. … the human emission of CO2 is totally insignificant for the Earth’s weather and climate and there is not one iota of reliable evidence that proves otherwise.”...
