Availability Entrepreneurs.
In the New York Times, John Tierney talks about "availability entrepreneurs", those people who selectively interpret some weather as evidence of global warming, yet ignore contradictory evidence:
Today’s interpreters of the weather are what social scientists call availability entrepreneurs: the activists, journalists and publicity-savvy scientists who selectively monitor the globe looking for newsworthy evidence of a new form of sinfulness, burning fossil fuels.A year ago, British meteorologists made headlines predicting that the buildup of greenhouse gases would help make 2007 the hottest year on record. At year’s end, even though the British scientists reported the global temperature average was not a new record — it was actually lower than any year since 2001 — the BBC confidently proclaimed, “2007 Data Confirms Warming Trend.”
He provides several examples of this bias, all well worth a read.
