Financier Soros to invest $1 billion in clean tech

Can a $1 billion help save the environment? George Soros hopes so.

The billionaire financier and philanthropist plans to invest part of his wealth on clean tech to fight global warming. In a speech at the Project Syndicate editors' forum in Copenhagen, Denmark, on Saturday, Soros gave the keynote address announcing his new plans.

Soros said he will invest $1 billion in clean-energy technologies and will provide $100 million--$10 million each year for the next 10 years--for the new Climate Policy Initiative, a watchdog-type foundation to promote measures to combat climate change.

Climate change taking toll on Glacier National Park

Note: All information in this story, unless otherwise noted, is from the National Park Service's pamphlets on and in-park signs about climate change and Glacier National Park.

GLACIER NATIONAL PARK, Mont.--The small graphics on a single sign, deep inside this incredible natural treasure says just about all you need to know about the drastic effects of rapid and intense climate change on the park and what's inside it.

"With warmer temperatures and changes to the water cycle, Glacier National Park will be glacier-free by 2030," the sign reads. "These changes will also have consequences … Read more

E-mails indicate EPA suppressed report skeptical of global warming

The Environmental Protection Agency may have suppressed an internal report that was skeptical of claims about global warming, including whether carbon dioxide must be strictly regulated by the federal government, according to a series of newly disclosed e-mail messages.

Less than two weeks before the agency formally submitted its pro-regulation recommendation to the White House, an EPA center director quashed a 98-page report that warned against making hasty "decisions based on a scientific hypothesis that does not appear to explain most of the available data."

The EPA official, Al McGartland, said in an e-mail message (PDF) to a … Read more

Why to buy into global warming

Tim O'Reilly makes the most cogent argument I've yet seen on why we should believe in global warming and act accordingly, even if we don't fully buy into the hype: The downside to belief is quite small. The upside is quite big.

In other words, it's a near-perfect application of Pascal's Wager, as Tim points out:

In my talks, I've argued that climate change provides us with a modern version of Pascal's wager: if catastrophic global warming turns out not to happen, the steps we'd take to address it are still worthwhile. … Read more

Asian air pollution could make U.S. summers hotter, but for how long?

So-called "short-lived" gasses and black particle pollution from power plants in Asia and transport in the United States could have a greater influence than previously predicted on temperature changes in North America and elsewhere on Earth, the U.S. National Oceanic and Atmospheric Administration reported last week. But is the headline the whole story?

While the general press and blog coverage of the report emphasizes Asia as a cause of warming in the United States, scientists also emphasized that better practices in energy-intensive economies with less-than-clean power plants could be an equally large opportunity for stabilizing the climate. … Read more

One-third of China's carbon emissions tied to exports

One-third of China's carbon emissions come from manufacturing electronics and other goods that are then exported worldwide, according to a July report in the journal Energy Policy.

The findings come from researchers led by Christopher Weber, a professor of civil and environmental engineering at Carnegie Mellon University.

Researchers measured 1.7 billion metric tons of carbon dioxide resulting from China's exporting industries in 2005. That rose from 760 million tons in 2002 and from 230 million tons in 1987, based on an analysis of economic and emissions reports from China.

In that time, carbon emissions from making electronics … Read more

Is Al Gore nuts?

In his speech in Constitution Hall this week, former Vice President and renewable energy investor Al Gore extolled a stretch goal challenging America to achieve 100% renewable power within 10 years.

The quote: "Today I challenge our nation to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years." And my favorite part: "When President John F. Kennedy challenged our nation to land a man on the moon and bring him back safely in 10 years, many people doubted we could accomplish that goal. But 8 years and … Read more

What Cleantech sector are the VCs after now?

As always, the venture community is looking for its next big thing. The cleantech world is no exception. Despite the dearth of exits, so much capital has flowed into the cleantech sector that investors need new places to put it. So despite my promise to certain friends not to blog certain funding rumors in each category, the top 4 contenders are:

Green building materials - I'm not sure it would be my thing, but investors across the board seem to think this area is ripe for a hit.

Carbon IT - With some sort of cap and trade a … Read more

Craig Venter's CO2-Eating Organisms

Craig Venter, who led the charge to decypher human DNA, is now on the green hunt. According to Treehugger he's looking for a double-wammy: take CO2 in the atmosphere and convert it into fuel (rather than fuel creating CO2 as is mostly the case today).

As we've described before, Venter's overarching goal is to produce microorganisms that are able to "convert things like sugar or sunlight or carbon dioxide into fuels that people are very familiar with, like diesel fuel and gasoline," as he himself put it. These would constitute not only the fabled second- … Read more
