Inside Story Americas – Holding Chevron accountable

Published on Nov 28, 2012 by AlJazeeraEnglish

After decades of oil drilling, they have seen their land destroyed, and their waters polluted. But members of Ecuador’s indigenous communities have yet to see a single penny for the damage inflicted on their lives by Chevron and its subsidiary, Texaco.

An “alarming” rate of Arctic Sea ice melt and “far-reaching changes” to the Earth from climate change follow a year of extremes, the World Meteorological Organization (WMO) said on Wednesday as the third day of climate negotiations take place in Doha, Qatar.

The WMO statement comes a day after the UN Environment Program (UNEP) warned that the looming release of methane in the Arctic could push the world past a “tipping point.”…..(more).

Food, Inc. – Documentary Film Trailer

Uploaded by povborders on Feb 1, 2010

Food Inc. A Documentary Film by Robert Kenner. The film airs on POV on April 21st.

How much do we know about the food we buy at our local supermarkets and serve to our families? Though our food appears the same as ever — a tomato still looks like a tomato — it has been radically transformed. In Food Inc., filmmaker Robert Kenner and investigative authors Eric Schlosser (Fast Food Nation), Michael Pollan (The Omnivore’s Dilemma) lift the veil on our U.S. food industry, revealing surprising facts about what we eat, how it’s produced, who we have become as a nation and where we may go from here.

All Biofuels Are ‘Nonsense’, Says Nobel-Winning Photosynthesis Expert Hartmut Michel

Well-Thought Out Argument Against Biofuels

Dr. Hartmut Michel won the Nobel Prize in Chemistry in 1988 for his work on photosynthesis, and he’s currently the director of the Molecular Membrane Biology department at the Max Planck Institute for Biophysics. It’s fair to say that he’s not only one of the smartest people in the world, but also one of the top experts on how plants turn sunlight into energy. To say that he’s qualified to comment on biofuels – which is basically all about turning sunlight into chemical energy via plants – is an understatement. His views on this topic should carry a lot of weight.

NOVA | Storm Surges and New York City

Days after Hurricane Sandy rumbled through the Northeast, New York City, the region’s economic hub, was struggling to get back on its feet. Crews were desperately scrambling to get the city’s crippled infrastructure operational. It wasn’t the hurricane force winds that were the problem, per se, but the extra seawater they had blown into the harbor. Salt water had crept into electrical substations, poured into basements, and cascaded into tunnels and subway stations. It swiftly corroded mechanical and electrical equipment, plunging much of the city south of 39th Street into darkness and shutting down hundreds of miles of transportation corridors. Nearly 400,000 people would return home, uncertain of what damage lie in wait for them.

Sandy was predicted to be a large storm, but no one had anticipated the height of the storm surge. Originally predicted to be up to 11 feet, it finally crested at 13.88 feet in Battery Park in Lower Manhattan. That’s over three feet above the previous record, set in 1960. Since then, the water level in New York Harbor has risen four to six inches, meaning the city will likely have to endure similarly threatening surges in the coming years. ….(more).

Could climate change be contributing to extreme weather events like Hurricane Sandy? Jennifer Francis, a climatologist at Rutgers University in New Jersey, believes that may be the case. In fact, her research shows that Arctic warming may have contributed to many of the extreme weather events of the past few years. Sam Eaton reports from New Jersey.

Listen to the story.

A climate scientist suggests that rapid warming in the Arctic helped create October’s “superstorm.”

David Robinson knows just about everything there is to know about climate change. But starting a borrowed chainsaw is another thing altogether.

“Ahh, this doesn’t look good,” Robinson sighs as he struggles with the cord. “This isn’t going to start.”

Robinson finally does get it started, and he and his son set to carving up a giant oak tree that fell in his son’s yard during Hurricane Sandy. He says chainsaws are one of the most common sounds around this part of New Jersey these days. …..(more).

Abstract

We analyse global temperature and sea-level data for the past few decades and compare them to projections published in the third and fourth assessment reports of the Intergovernmental Panel on Climate Change (IPCC). The results show that global temperature continues to increase in good agreement with the best estimates of the IPCC, especially if we account for the effects of short-term variability due to the El Niño/Southern Oscillation, volcanic activity and solar variability. The rate of sea-level rise of the past few decades, on the other hand, is greater than projected by the IPCC models. This suggests that IPCC sea-level projections for the future may also be biased low. [emphasis added]

Doha climate talks: US defends ‘enormous’ efforts

Negotiator Jonathan Pershing says America deserves more credit for the ‘scale and extent’ of its action

The United States defended its track record on fighting climate change on Monday as UN talks began in Doha, saying it is making “enormous” efforts to slow global warming and help the poor nations most affected by it.

Other countries have accused Washington of hampering the climate talks ever since the Bush administration abandoned the Kyoto protocol, the 1997 treaty limiting emissions of heat-trapping gases by industrialised countries. As negotiators met for a two-week session in oil and gas-rich Qatar, US delegate Jonathan Pershing suggested America deserved more credit.

“Those who don’t follow what the US is doing may not be informed of the scale and extent of the effort, but it’s enormous,” Pershing said.

He noted that the Obama administration has taken a series of steps, including sharply increasing fuel efficiency standards for cars and trucks, and made good on promises of climate financing for poor countries. A climate bill that would have capped emissions stalled in the Senate.

“It doesn’t mean enough is being done,” Pershing said. “It’s clear the global community, and that includes us, has to do more if we are going to succeed at avoiding the damages projected in a warming world.” ….(more).
