The opposition argument: No Need to Decarbonize, say 16 scientists

with one comment

TRC works daily on behalf of and cares greatly about the future of this planet and its human and non-human inhabitants. As a result, TRC take seriously the dangers inherent in pumping carbon dioxide into the atmosphere in volumes that we do. We believe the scientific community when it says: climate change is real, and we are causing it. The results stand over and over. This is our position.

But not everyone agrees. In fairness to the science of climate change, TRC feels it is worthwhile to post this editorial from the WSJ, signed by 16 scientists, arguing against the need to take drastic action on climate change.

Titled No Need to Panic on Global Warming, the op-ed is a cool and considerate argument that there is no evidence in the science that points towards a need to decarbonize our global economy. There are many problems in the argument presented here, in my opinion, but I will note that the main reasons this group of scientists do not want to take action boils down to very familiar arguments: CO2 is good for the planet, scientists are strong-armed by the alarmists into submission, and the benefits of carbon-free investment are not worth the costs.

Here’s some excerpts.

  • The fact is that CO2 is not a pollutant. CO2 is a colorless and odorless gas, exhaled at high concentrations by each of us, and a key component of the biosphere’s life cycle. Plants do so much better with more CO2 that greenhouse operators often increase the CO2 concentrations by factors of three or four to get better growth. This is no surprise since plants and animals evolved when CO2 concentrations were about 10 times larger than they are today. Better plant varieties, chemical fertilizers and agricultural management contributed to the great increase in agricultural yields of the past century, but part of the increase almost certainly came from additional CO2 in the atmosphere.
  • Although the number of publicly dissenting scientists is growing, many young scientists furtively say that while they also have serious doubts about the global-warming message, they are afraid to speak up for fear of not being promoted—or worse. They have good reason to worry. In 2003, Dr. Chris de Freitas, the editor of the journal Climate Research, dared to publish a peer-reviewed article with the politically incorrect (but factually correct) conclusion that the recent warming is not unusual in the context of climate changes over the past thousand years. The international warming establishment quickly mounted a determined campaign to have Dr. de Freitas removed from his editorial job and fired from his university position. Fortunately, Dr. de Freitas was able to keep his university job.
  • There is no compelling scientific argument for drastic action to “decarbonize” the world’s economy. Even if one accepts the inflated climate forecasts of the IPCC, aggressive greenhouse-gas control policies are not justified economically.
  • A recent study of a wide variety of policy options by Yale economist William Nordhaus showed that nearly the highest benefit-to-cost ratio is achieved for a policy that allows 50 more years of economic growth unimpeded by greenhouse gas controls. This would be especially beneficial to the less-developed parts of the world that would like to share some of the same advantages of material well-being, health and life expectancy that the fully developed parts of the world enjoy now. Many other policy responses would have a negative return on investment. And it is likely that more CO2 and the modest warming that may come with it will be an overall benefit to the planet.
