To me, it's just another sign of the overwhelming complexity that so many people can be swayed by bullshit and outright lies. When the evidence is staring you in the face, when ice is disappearing all over the planet, temperatures are rising, habitats moving, destructive storms increasing, winters warming... when every sign points to the clear, undeniable evidence and there is, literally ZERO scientific evidence to support any other conclusion, one can only conclude that we prefer our delusions and will defend them at any cost. Or, that those who possess power will lie the world into mass destruction before giving up that power. And that is possible only because it is impossible for the average person to know for certain who is lying and who isn't.
We aren't scientists. It wasn't that long ago that the basic daily lives of scientists was much like that of you and I. We all observed the same world. But now? Now scientists' daily life experiencea are nothing like ours. We have little ability to judge what we are being told is reality, so we are susceptible to the lies and propaganda that power and ideology generate to hold onto the last vestiges of the power and wealth that fossil fuels made possible.
But it is possible to know. Just look around you. And don't pretend to yourself that scientists sit around contemplating separating you from your wallets because some uneducated idiot on the radio, in the newspaper, on TV or in Congress tells you so. For, if you are willing to accept that virtually every climate scientist on the planet is in a conspiracy to control the world, then the whacko is the one in the mirror.
Think about it. For a person to deny climate science due to some conspiracy theory involving virtually every climate scientist, every major science organization, and from every nation on the planet, not only means to do the preceding, but it means it had to start more than a hundred years ago when the problem of green house gases was first identified. And if we are willing to do that, then how does one trust **any other** science? Why should we trust cars or airplanes? They exist because of science. How can you trust doctors? After all, they're paid to treat your illnesses. Maybe they're the ones making us sick! How do we trust our computers? They are how we see and hear all our info an news these days, so they must be filling us with nanobots to control us!
It's time to come back from the era of the Salem Witch trials and re-enter the current century. A letter from climate scientists to you:
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.
