Lightning displays above erupting volcano

Lightning bolts appear above and around the Chaiten volcano as seen from Chana, some 30 kms (19 miles) north of the volcano, as it began its first eruption in thousands of years, in southern Chile on May 2, 2008. Cases of electrical storms breaking out directly above erupting volcanoes are well documented, although scientists differ on what causes them. (Pictures taken May 2, 2008. Carlos Gutierrez/Reuters)

June at Spatter writes about "ostriches" after discovering over 50% of the people surveyed about global warming are "not very concerned" (11.5%) or "not convinced it's true" (38.9%). Not convinced? Ask the dying polar bears, whose habitat is rapidly melting.
