Soot worse for global warming than thought

Soot particles may be twice as bad as the greenhouse gas carbon dioxide in contributing to global warming, suggests a new study.

Grains of soot deposited in snow have also caused about one-quarter of the observed rise in global surface temperature since 1880, suggests the model by James Hansen and Larissa Nazarenko. The pair examined how soot particles affect the atmosphere when they darken snow and ice.

Darkened snow traps more solar energy than pristine snow. The effect could explain why sea ice and glaciers are melting faster than expected from the increase in surface temperature alone, says Hansen of the NASA Goddard Institute for Space Studies in New York.

“The effect of soot on snow is unambiguous,” he told New Scientist. “It causes a strong warming effect.”

Obama’s Secretary Of Energy confesses his unwavering faith in the holy climate models.

Chu noted that even the most optimistic climate models for the second half of this century suggest that 30 to 70 percent of the snowpack will disappear. “There’s a two-thirds chance there will be a disaster,” Chu said, “and that’s in the best scenario.”
