NASA scientists produced this image to study the behavior of aerosols -- tiny airborne particles -- in the Earth's climate system. Dust, in red, is lifted from the surface. Sea salt, in blue, swirls inside cyclones. Smoke, in green, rises from fires. Sulfate particles, in white, stream from volcanoes and fossil fuel emissions, NASA writes.

InsideClimateNews (Berlin) -- The view from the Reichstag roof on a sun-drenched spring afternoon is spectacular. Looking out over Berlin from the seat of the German government, you can see the full sweep of the nation's history: from Humboldt University, where Albert Einstein taught physics for two decades, to the site of the former Gestapo headquarters.
I'm not here to see this country's freighted past, however. I've come to learn about what a majority of Germans believe is their future—and perhaps our own. There is no better place to begin this adventure than the Reichstag, rebuilt from near ruins in 1999 and now both a symbol and an example of the revolutionary movement known as the Energiewende. The word translates simply as, "energy change." But there's nothing simple about the Energiewende. It calls for an end to the use of fossil fuels and nuclear power and embraces clean, renewable energy sources such as solar, wind and biomass. The government has set a target of 80 percent renewable power by 2050, but many Germans I spoke with in three weeks traveling across this country believe 100 percent renewable power is achievable by then.Read more »
InsideClimateNews.org (Zingst, Germany) —"What an eyesore, huh?" the man standing next to me on the beach said, nodding in the direction of a little girl flying a kite. The man, in his mid-40s, seemed to enjoy my confusion. He waited a beat before pointing beyond the girl, far out into the Baltic Sea. "There," he said, smiling to make sure I understood his sarcasm. "The 'ugly' wind farm."
Staring hard, it was barely possible to make out the turbines on the horizon. Ten miles from shore, the Baltic 1 Wind Farm seemed as small and insubstantial as the scruffy grass along the coast. But, in fact, each of the nearly two dozen turbines is as tall as a 27-story building and has fiberglass epoxy blades nearly 150 feet long. Work has already begun on wind farms with even larger turbines that will generate twice the power of those at Baltic 1, enough to supply 250,000 households with electricity.Read more »
World Resources Institute -- With President Obama’s re-election, he has the opportunity to extend his legacy and take on big challenges. Climate change stands high on the list of issues that need to be addressed. As the President said in his acceptance speech:
“We want our children to live in an America that isn’t burdened by debt, that isn’t weakened by inequality, that isn’t threatened by the destructive power of a warming planet.”
In the final days of the campaign, Hurricane Sandy provided a wake-up call about the impacts of climate change. Recent extreme weather and climate events make clear that ignoring climate change will be costly in human, environmental, and economic terms for the United States and the world. How President Obama addresses climate and energy issues will help define his legacy.Read more »
Agriculture and industry produce huge amounts of leftover carbon -- hiding in the tips and branches of trees, stalks, husks and other plant material. If only there was a way to put it to good use.
Kior Inc. announced today the opening of its first commercial-scale plant designed to do just that. The facility, located in Columbus, Mississippi, at full capacity will take in 500 tons of biomass a day and transform it into what sounds like a contradiction in terms -- 40,000 gallons a day of gasoline and diesel that could help companies meet their renewable energy goals or mandates. Kior's next plants may be at least three times as large. The company’s technology uses catalysts to vaporize biomass, removing the oxygen and condensing the remainder to oil that can be refined into cellulosic gasoline, diesel and jet fuel. Silicon Valley powerhouse Khosla Ventures owns more than half of the five-year-old company, which is based in Pasadena, Texas.Read more »
Eleven years, one month, three weeks and five days ago I stood on West Street in southern Manhattan and watched many hundreds of people murdered, as a gray avalanche of concrete, glass and steel poured forth from a disintegrating tower to the street below. The 9/11 attacks changed everything, for all time, and we all felt it instantaneously.
Superstorm Sandy delivers a message first heard on Sept. 11, 2001: New York, as a proxy for the United States, is unprepared for anticipated 21st century threats.Read more »
Sure, it would be rash to describe Hurricane Sandy as climate change incarnate. But it does make one wonder just how much longer we can ignore the bigger picture.
The bigger picture is that of a storm eating the northeastern United States from the Carolinas in the South to Lake Michigan in the West. More than 60 million Americans have been affected, many of them in areas where hurricane damages have not historically been a concern. Initial estimates by Eqecat put insured losses at $10 billion to $20 billion, with up to another $50 billion in economic damages. Once economists tally the total losses from property damage to homes, stores, cars, and utilities, as well as the opportunity costs of foregone wages and other productivity losses, the figure is likely to be even higher.Read more »
Hurricane Sandy was a massive and deadly storm, extending more than 1,000 miles, bringing huge waves and more than 13 feet of water to parts of New York City. In Manhattan, floods swept away cars and overflowed subway stations. Along the Jersey shore, homes, property, and businesses were washed away in just a few hours. More than 8 million people in the northeastern United States lost power. Tens of millions more have been affected. And, tragically at least 160 people lost their lives in total. Outside of the United States, six Caribbean countries were battered by the storm, taking lives and destroying property as it struck. Some early estimates say the storm will cost $50 billion; others say it will be more.
Sadly, science tells us that this type of event will become much more common as our climate continues to change.Read more »
Research has shown for several years that Manhattan faces serious flood risk.
A 2008 study concluded that New York was vulnerable to storm-surge flooding from even a moderate storm and recommended that local authorities build protections as other cities have. The Fox Point Hurricane Barrier, which spans the Providence River in Rhode Island, was built in the middle of the last century after major storms. London's Thames Barrier has protected London since 1982.Read more »
