Wait a minute, what about that 97 percent consensus?The message was clear: “There is no climate emergency.”With those five simple words, a global network of scientists and professionals attempted to inject reasonableness and decorum into what should be a robust discussion about a complex scientific and public policy issue, but has instead degenerated into an ever more intense mud-slinging contest over the years.People on one side of the argument dismiss their opponents as wild-eyed socialists attempting to leverage public fear and ignorance to further their political agenda. On the opposite side, people dismiss those who disagree with their supposedly settled scientific conclusions as nothing more than knowing shills or ignorant dupes of evil energy interests.In between those extremes that are so popular with armies of public relations professionals, who shape the messages of public interest groups and professional politicians to maximum effect, are a not-so-quiet silent majority of scientists and professionals who take a more measured, reasoned view of the science when considering the supposed climate emergency some say we’re facing.A group of 500-some scientists and professionals signed on to the “European Climate Declaration” that was released last week. This simple, short, and understandable statement proposed how analysis of any public policy issue involving complex science should be approached from a reasoned, fact-based perspective.
The signatories have also sent a letter to UN Secretary-General Antonio Guttierez. We shall see if he has any response.Statements such as “97 percent of climatologists agree that anthropogenic climate change is occurring” isn’t a statement of fact, it’s an opinion twice removed. It’s an opinion that involves evaluation of the legitimacy of how the results of the poll in question were sorted to dismiss some answers and allow others, and it’s an opinion in terms of how representative the sample size is with respect to all climate professionals.Statements such as “modeling shows that catastrophic climate change will occur in the next [pick a number] years unless drastic changes are made” is also an opinion. It’s an opinion because the results of any model, and in particular any model that purports to predict the future of anything as complex as the entire planet’s climate system, necessarily relies on a multitude of choices made by the model’s designer. The relative importance of the many, many factors that go into the model’s complex calculations are based on the judgments of the model designer, and those judgments are matters of opinion, not statements of fact.
Three big takeaways from the declaration:
One: “The world has warmed at less than half the originally predicted rate, and at less than half the rate to be expected on the basis of net anthropogenic forcing and radiative imbalance. It tells us that we are far from understanding climate change.”
Two: “Climate models have many shortcomings and are not remotely plausible as policy tools. Moreover, they most likely exaggerate the effect of greenhouse gases such as CO2. In addition, they ignore the fact that enriching the atmosphere with CO2 is beneficial.”
Three: “There is no climate emergency. Therefore, there is no cause for panic and alarm. We strongly oppose the harmful and unrealistic net-zero CO2 policy proposed for 2050. If better approaches emerge, we will have ample time to reflect and adapt. The aim of international policy should be to provide reliable and affordable energy at all times, and throughout the world.”Thank you, signatories.
Big money in tha pleasant sounding phrase "reliable and affordable." Ignorant armies (of public relationa professionals) clashing in the night. What are mere citizens of Planet Earth to do to sort it all out?
