FableThis painting by Gustav Klimt was created in 1883, the same year as the Krakatoa eruption. Researchers analyzed the color of the sky to gauge atmospheric pollution levels in the past. … [Read more...] about Volcanoes in Art: A Gallery of Climate Change Clues
Climate change adaptation strategies in agriculture
Harvard’s Keith leads a team that wants to conduct an albedo experiment that involves releasing roughly one-half kilogram of sulfuric acid particles into the stratosphere to study its effects on ozone. “The agencies say they're waiting from guidance from [the White House Office of Science and Technology Policy], but OSTP says the agencies can do what they want,” he says. (OSTP declined to address Keith's comment, though a White House official said the administration would review the reports.) He hopes the new report might help end such gridlock. … [Read more...] about U.S. should fund climate engineering research, report concludes
Some researchers believe these changes are so big that they mark the beginning of a new "human age" of Earth history, the Anthropocene epoch. A committee of geologists has now proposed to mark the start of the Anthropocene in the mid-20th century, based on a striking indicator: the widely scattered radioactive dust from nuclear bomb tests in the early 1950s. … [Read more...] about Anthropocene? Humans Have Been Changing the Planet for Millennia.
International relations professor Simon Nicholson, who co-runs the Forum for Climate Engineering Assessment at American University in Washington, D.C., says the new call for federal geoengineering research, in the last days of the Obama administration, is “ironic and extraordinarily sad.” Nicholson, like many researchers, has wanted federal research agencies to support more work in this area. Now, he fears that having “climate intervention on the radar of the new administration would be a distraction.” He’s reluctant to discuss the idea, he says. “The most important work to do with the new administration is to be sure they keep intact important international work on climate mitigation and adaptation.” Over the long term, he worries that climate skeptics in the policy world, after dismissing climate change as a risk in recent years, could later change positions and say it was real, embracing climate engineering “as this magic solution … [Read more...] about U.S. should pursue controversial geoengineering research, federal scientists say for first time
One is to inject sulfur dioxide or a similar aerosol into the stratosphere to help shade the Earth from more intense sunlight. It is patterned after a natural solution: volcanic eruptions, which have been found to cool the Earth by emitting huge clouds of sulfur dioxide. … [Read more...] about U.S. geoengineering research gets a lift with $4 million from Congress
