Hmmh … . Even though it’s more than four years old, Censoring Science was reviewed just the other day on the Daily Kos. Might have something to do with the fact that this is an election year. And, come to think of it, it might be worthwhile to refresh our memories about the brutal tactics of the last Republican administration, since they will almost certainly return if a Republican wins the election this year. After all, as I show in the book, every Republican administration since 1988, when Jim Hansen turned global warming into a public issue, has censored government scientists who work in this area.

Somehow I can’t seem to leave global warming behind …

Ed Douglas is a fine writer and an avid climber, whom I once met over dinner at a friend’s house in England. We had a memorable conversation, to which he refers in an opinion piece that was published yesterday in the Guardian (UK). I fully agree with Ed’s call for climbers to bear witness to the catastrophic effects of global warming in our beloved mountains. We must also work to debunk the myth being propogated by global warming deniers that anecdotal evidence–i.e., facts that are so obvious that they slap you in the face, such as the present wasting away of the world’s mountain glaciers–is somehow unscientfic and therefore easily ignored.

There is nothing magical about science; it is simply observation of the physical world, coupled with deduction and insight. What is magical thinking is the way some people–both of the leading contenders for the Republican nomination for U.S. President, for example–continue to deny the unassailable evidence for human-induced climate change (links here and here).

Climbers are perfectly placed to make accurate observations of the mountain world. Who better to ask about changes in that world than those whose very lives depend on their ability to observe it?

You will find blog posts related to Ed’s opinion piece here, and here. (The latter is a complete draft of the 2001 article that I wrote for Climbing, which was the subject of an absurd controversy that was manufactured by the denial lobby at the beginning of last year.)

I recommend Ed’s biography of Tenzing Norgay, as well as his most well-known book, Chomolungma Sings The Blues.

A thoughtful opinion piece by Root Routledge. Check it out and then send it to those of your friends who call themselves skeptics.  Most likely, they are actually misinformed …

This is the best thing I’ve read lately about the fundamental facts and the fictional “debate” about global warming, the latter of which, as I’ve pointed out before, is actually a public relations war. The letter was written by dozens of members of the United States National Academy of Sciences. They submitted it to a number of news outlets who refused to print it, including the New York Times. It was ultimately published in Science (link).

Please read this.

Thanks,

Climate Change and the Integrity of Science

We are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular. All citizens should understand some basic scientific facts. There is always some uncertainty associated with scientific conclusions; science never absolutely proves anything. When someone says that society should wait until scientists are absolutely certain before taking any action, it is the same as saying society should never take action. For a problem as potentially catastrophic as climate change, taking no action poses a dangerous risk for our planet.

Scientific conclusions derive from an understanding of basic laws supported by laboratory experiments, observations of nature, and mathematical and computer modeling. Like all human beings, scientists make mistakes, but the scientific process is designed to find and correct them. This process is inherently adversarial—scientists build reputations and gain recognition not only for supporting conventional wisdom, but even more so for demonstrating that the scientific consensus is wrong and that there is a better explanation. That’s what Galileo, Pasteur, Darwin, and Einstein did. But when some conclusions have been thoroughly and deeply tested, questioned, and examined, they gain the status of “well-established theories” and are often spoken of as “facts.”

For instance, there is compelling scientific evidence that our planet is about 4.5 billion years old (the theory of the origin of Earth), that our universe was born from a single event about 14 billion years ago (the Big Bang theory), and that today’s organisms evolved from ones living in the past (the theory of evolution). Even as these are overwhelmingly accepted by the scientific community, fame still awaits anyone who could show these theories to be wrong. Climate change now falls into this category: There is compelling, comprehensive, and consistent objective evidence that humans are changing the climate in ways that threaten our societies and the ecosystems on which we depend.

Many recent assaults on climate science and, more disturbingly, on climate scientists by climate change deniers are typically driven by special interests or dogma, not by an honest effort to provide an alternative theory that credibly satisfies the evidence. The Intergovernmental Panel on Climate Change (IPCC) and other scientific assessments of climate change, which involve thousands of scientists producing massive and comprehensive reports, have, quite expectedly and normally, made some mistakes. When errors are pointed out, they are corrected. But there is nothing remotely identified in the recent events that changes the fundamental conclusions about climate change:

(i) The planet is warming due to increased concentrations of heat-trapping gases in our atmosphere. A snowy winter in Washington does not alter this fact.

(ii) Most of the increase in the concentration of these gases over the last century is due to human activities, especially the burning of fossil fuels and deforestation.

(iii) Natural causes always play a role in changing Earth’s climate, but are now being overwhelmed by human-induced changes.

(iv) Warming the planet will cause many other climatic patterns to change at speeds unprecedented in modern times, including increasing rates of sea-level rise and alterations in the hydrologic cycle. Rising concentrations of carbon dioxide are making the oceans more acidic.

(v) The combination of these complex climate changes threatens coastal communities and cities, our food and water supplies, marine and freshwater ecosystems, forests, high mountain environments, and far more.

Much more can be, and has been, said by the world’s scientific societies, national academies, and individuals, but these conclusions should be enough to indicate why scientists are concerned about what future generations will face from business-as-usual practices. We urge our policy-makers and the public to move forward immediately to address the causes of climate change, including the unrestrained burning of fossil fuels.

We also call for an end to McCarthy-like threats of criminal prosecution against our colleagues based on innuendo and guilt by association, the harassment of scientists by politicians seeking distractions to avoid taking action, and the outright lies being spread about them. Society has two choices: We can ignore the science and hide our heads in the sand and hope we are lucky, or we can act in the public interest to reduce the threat of global climate change quickly and substantively. The good news is that smart and effective actions are possible. But delay must not be an option.
