Every country may have to consider what, if anything, to do about “global warming”. We should understand that the oft-repeated claim that nearly all scientists demand that something dramatic be done to stop global warming is not true.

Perhaps the most inconvenient fact is the lack of global warming for well over 10 years now. This is known to the warming establishment, as one can see from the 2009 “Climategate” email of climate scientist Kevin Trenberth: “The fact is that we can’t account for the lack of warming at the moment and it is an irony that we can’t.” But the warming is only missing if one believes computer models where so-called feedback involving water vapor and clouds greatly amplifies the small effect of CO2. The fact is that CO2 is not a pollutant and it is a key component of the biosphere ( 生物圈)’s life cycle. Plants get better growth with more of it and part of the increase of agricultural yields in the past century certainly came from additional CO2 in the atmosphere.

Although the number of the scientists who are publicly opposed to the claim is growing, many young scientists secretly 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.

Why is there so much passion about global warming? There are several reasons, but a good place to start is the old question “Cui bono?”, or the modern update, “Follow the money”. Alarmism (危言耸听) over climate is of great benefit to many, providing government funding for academic research, and thus those people who benefit from this fiercely defended their dogma (信条) and the privileges it brought them.

Every country should support rational ( 合理 的) measures to protect and improve our environment, but it makes no sense at all to back expensive programs that turn away resources from real needs and are based on alarming but shaky claims of “incontrovertible” evidence.
