...discreet puff. Indeed, France's cannabis culture has become so prevalent that the use of the word petard is as likely to refer to a joint as to its more literal meaning, "firecracker." Myriad nicknames for hash and marijuana have passed into the modern lexicon, such as chichon, beuh, teuteu, matos and teuch - the latter being an approximate phonic reversal of the borrowed English word most commonly used for hashish (hint: bulls produce...
That is one reason the latest IPCC predictions for temperature increase are higher than they were five years ago. Back in the mid-1990s, climate models didn't include the effects of the El Chichon and Mount Pinatubo volcanic eruptions, which threw enough dust into the air to block out some sunlight and slow down the rate of warming. That effect has dissipated, and the heating should start to accelerate. Moreover, the IPCC noted, many countries have begun to reduce their emissions of sulfur dioxide in order to fight acid rain. But sulfur dioxide particles, too, reflect sunlight; without this...

...frequency waves that resonate through the magma itself. While their origin remains a mystery, these vibrations may result from small surges of gas and molten rock. Large numbers of such signals preceded Mount St. Helens' 1980 blast. They also appeared before the unexpected explosion of Mexico's El Chichon in 1982, the blowup of Colombia's Nevado del Ruiz in 1985 and 1987 and multiple eruptions of Alaska's Redoubt. Seismometers positioned at Pinatubo have recorded similar seismic patterns...
...Offsetting the obvious weaknesses of climate models, says Warren Washington, who developed the model now used at NCAR, is one significant advantage. "They are experimental tools that allow us to test our hypotheses," he says. "We can ask such questions as 'What happens when a big volcano like El Chichon goes off?' and 'How much will the earth warm up by 2030 if we continue to dump CO2 into the atmosphere...
