From “global warming” to “climate change” to “ecosystem management,” the buzzwords have changed, but the issue remains: enthusiasm and hype are part of the PR machine that drives the public perception of science. When well-meaning activists rely on emotions as a shortcut to get the cooperation of the public, the fabric of civic discourse is [...]

I’ve been blogging about the climate change issue for some time now. Here’s the latest, which responds to the exposure of private e-mails in which a climatologist is accused of acknowledging deliberately tweaking the data in order to make a stronger environmental case. [N]ot only did British investigators clear the East Anglia scientist at the center [...] It is dangerous to use local weather events (such as a heavy or light winter) to make judgments about global climate. With that caveat, I’m blogging the following because I’ve noted a shift in the online discussion about “global warming,” or the more general “climate change”. This essay does a good job exploring the events [...] While the Church gets a lot of guff for its skeptical responses to Galileo’s astronomical findings, some Jesuit astronomers not only listened to his ideas but repeated his observations, and some university faculty members flatly refused to look through a telescope. Simplistic representations of scientific issues, with heroes and villains, make good stories, but rarely [...] The Australian publishes an interesting detail about coverage of climate change: Duffy asked Marohasy: “Is the Earth still warming?” She replied: “No, actually, there has been cooling, if you take 1998 as your point of reference. If you take 2002 as your point of reference, then temperatures have plateaued. This is certainly not whethat [...] Times Online: In December 2005 a study in the journal Nature offered the observation that the circulation in the North Atlantic Ocean, which sustains the Gulf Stream, had weakened by up to 30 per cent over the previous few decades. This figure and its juxtapositioning alongside the melodrama of films such as The Day [...] ‘One approach to seeing the future is through scenarios — carefully crafted “what if?” stories that let us imagine several different outcomes’, the book says. It suggests holding a ‘scenario party’ (seriously) where you can ‘pool the imaginations and experiences of your friends’. In short: we have no idea what the future will look like, [...] Solar scientists predict that, by 2020, the sun will be starting into its weakest Schwabe solar cycle of the past two centuries, likely leading to unusually cool conditions on Earth. Beginning to plan for adaptation to such a cool period, one which may continue well beyond one 11-year cycle, as did the Little Ice Age, [...] The words “global warming” provoke a sharp retort from Colorado State University meteorology professor emeritus William Gray: “It’s a big scam.” And the name of climate researcher Kevin Trenberth elicits a sputtered “opportunist.” At the National Center for Atmospheric Research, where Trenberth works, Gray’s name prompts dismay. “Bill Gray is completely unreasonable,” Trenberth says. “He [...] The former vice president’s movie — replete with the prospect of a flooded New York City, an inundated Florida, more and nastier hurricanes, worsening droughts, retreating glaciers and disappearing ice sheets — mostly got the science right, said all 19 climate scientists who had seen the movie or read the book and answered questions from [...] |
