DemocracyNow.org – Extreme weather from Texas to Somalia may indicate that a new era of climate war is upon us. Just this month, massive floods have shut down two nuclear power facilities in Nebraska. In New Mexico, the nation’s top nuclear weapons lab in Los Alamos is being threatened by an uncontrolled wildfire. Meanwhile, the United Nations warns the Horn of Africa is facing its worst drought in 60 years, affecting more than 10 million in Djibouti, Ethiopia, Kenya, Somalia and Uganda. Democracy Now! interviews award-winning journalist Christian Parenti who argues in his new book that global warming is leading to social and environmental catastrophe. “The weather associated with climate change, extreme weather such as the drought, punctuated by flooding in East Africa, punctuated by flooding in East Africa, is adding to this.Climate change very often doesn’t just look bad weather, it looks like ethnic violence or religious violence or banditry or civil war,” says Parenti.

Christian Parenti, contributing editor at the Nation. Author of several books, most recently, “Tropic of Chaos: Climate Change and the New Geography of Violence.”

B McKibben C Parenti: 2013 “Year Zero” in the Battle over Climate Change ?

Further informations about topics addressed are available in favourites, play lists on my channels and complementary video responses. Mirrored and published with the permission of: DemocracyNow.org – We host a conversation about how to confront global warming it with 350.org founder Bill McKibben and journalist Christian Parenti. Some have called 2013 “year zero” in the battle over climate change. This comes as 2012 was a year of extreme weather, from the melting of the Arctic, to Superstorm Sandy, to the massive typhoon in the Philippines. It was also the warmest year on record in the United States, with massive droughts and frequent wildfires. In the U.S. presidential debates, neither of the major party candidates took on climate change. But right after the election, McKibben and 350.org hit the road to begin a campaign focused on confronting the role of the fossil fuel industry — what McKibben calls, “Public Enemy Number One to the survival of our planetary civilization.” The tour has since ended, but the fossil fuel divestment campaign it launched is growing. Many environmentalists welcome the fossil fuel divestment campaign as the new frontier in their activism, but some have raised questions about the effectiveness of a widespread fossil fuels divestment campaign, including Parenti, who wrote the recent article, “Problems With the Math: Is 350’s Carbon Divestment Campaign Complete?” We host a discussion about the campaign with McKibben, who was just voted “Vermonter of the Year” by the Burlington Free Press and is the author of “Eaarth: Making A Life On A Tough New Planet.” Parenti is professor of sustainable development at the School for International Training and the author of “Tropic of Chaos: Climate Change and the New Geography of Violence.”

Climate Change May Increase Volcanic Eruptions | Janurary 3rd; 2013

The rapid rise in sea levels could cause a dramatic increase in volcanic eruptions, according to a new study.

The study, published in the journal Geology, found that during periods of rapid climate change over the last million years, the rapid melting of continental glaciers and the resulting sea-level rise eventually increased volcanic eruptions as much as fold.

“Everybody knows that volcanoes have an impact on climate,” said study co-author Marion Jegen, a geophysicist at Geomar in Germany. “What we found was just the opposite.”

The findings were based only on natural changes in climate, so it’s not clear whether human-caused climate change would have the same impact, Jegen said. And if it did, she added, the effect wouldn’t be seen for centuries.

Volcanic changes

It’s long been known that volcanism can dramatically alter the climate, often in cataclysmic ways. For instance, mass extinctions such as the one at the end of the Permian period may have been caused by continuous volcanic eruptions that cooled the climate and poisoned the atmosphere and the seas. [50 Amazing Volcano Facts]

But few people thought climate change could fuel volcanic eruptions before Jegen and her colleagues began looking at cores drilled from the oceans off of South and Central America. The sediments showed the last 1 million years of Earth’s climatic history.

Every so often, shifts in Earth’s orbit lead to rapid warming of the planet, massive melting of glaciers and a quick rise in sea levels. The team found that much more tephra, or layers of volcanic ash, appeared in the sediment cores after those periods. Some places, such as Costa Rica, saw five to 10 times as much volcanic activity during periods of glacial melting as at other times, Jegen told LiveScience.

To understand why that would be, the research team used a computer model and captured how those changes affected the pressures experienced at different places on the Earth’s crust. The team found that when glaciers melt, they reduce the pressure on continents, while sea-level rise increases pressures on the ocean floor crust. In the computer model, the change in pressures on the Earth’s crust seem to cause increases in volcanism.

In general, the speed of the transition from ice age to melting, rather than the total amount of melting, predicted how intensely the volcanic eruptions increased, she said.

The study doesn’t address whether modern-day climate change would have any impact on the frequency of volcanic eruptions, though in theory it’s possible, Jegen said.

But even if anthropogenic, or human-caused, climate change impacts volcanic eruptions, people wouldn’t see the effect in this lifetime, because the volcanic activity doesn’t occur immediately after the climate change, Jegen said.

“We predict there’s a time lag of about 2,500 years,” Jegen said. “So even if we change the climate, you wouldn’t really expect anything to happen in the next few thousand years.”
