Now that project appears to have hit a snag. While the site the consortium picked to build the project was selected in December as Mattoon, Illinois, after a short delay in responding, the DOE is … Read more
For some 4.5 billion years, natural forces such as volcanic eruptions, asteroid strikes, and earthquakes have shaped the Earth.
They blame the industrial revolution for a new geologic epoch, dubbed the Anthropocene. Stresses to the planet's atmosphere, oceans, life forms, and very surface are dramatic enough to end the Holocene epoch, the geologists say. That period began about 12,000 years ago as the last Ice Age melted and the planet warmed enough … Read more
To curb global warming, we're going to have to crack down on greenhouse gases in a big way, says the American Geophysical Union.
The AGU, an organization that publishes and promotes geophysical research, issued a statement Thursday stating that, to avoid a 2-degree Celsius rise in average temperatures, carbon dioxide emissions will have to be cut in half during the century.
"In the next 50 years, even the lower limit of impending climate change--an additional global mean warming of 1 degree C above the last decade--is far beyond the range of climate variability experienced during the past thousand … Read more
Meraki, a start-up that hopes to bring cheap Wi-Fi to the emerging world, has raised $20 million in a second round of funding.
The company, which grew out of a Ph.D. thesis at MIT, has created inexpensive routers and a back-end networking service that balances available bandwidth between the routers and users. The end result is that the available bandwidth is used more efficiently, according to Sanjit Biswas, Meraki's CEO and co-founder.
"There are a small number of Internet connections, but they are repeated by a large number of radios" in networks based on the company'… Read more
Most Americans now agree that something needs to be done to reduce our greenhouse gas emissions. Hopefully most Americans now appreciate that this is not a small, but even more so, not a simple problem. I am a big believer that the playing field for our low carbon future should start level, and the market should be structured to allow our major power and energy companies a chance to lead the way, instead of simply dishing out punishment for our combined historical choices. Carrots and sticks work well together, but sticks alone are not going to solve our global carbon … Read more
Correction at 3:30 p.m. PST Thursday: Blame my Rust Belt ignorance. The Ohio river that burned is the Cuyahoga.
SAN FRANCISCO--I've been spending some time at the the American Geophysical Union conference here, and I've had a recurring thought: When it comes to apocalyptic predictions, geophysicists have the Book of Revelations beat, hands down.
Sometime in the last few years, the idea that global warming is a reality and that it's caused in large measure by people has finally started sinking in. But perhaps because of the remaining skepticism, and more likely because of the … Read more
SAN FRANCISCO--Warmth may not be an attribute you associate with a place where the sun doesn't shine in the winter and the sea freezes over, but all things are relative. And compared to earlier years, the Arctic was downright sweltering this year.
According to new research presented here at the the American Geophysical Union conference, the Arctic Ocean reached record high temperatures, arctic ice diminished to a record low, and ice melted on Greenland for a record number of days.
SAN FRANCISCO--Researchers have linked global climate change to a tripling in the frequency of large fires in major forests of Alaska and Canada.
Black spruce forests cover about 2.7 million square kilometers in Canada and Alaska--about a third of the area of the lower 48 states of the U.S., and fire records date back to the 1950s. Beginning around 1987, the rate that large wildfires struck the forest jumped from about once every 10 years to once every 3 years, said Eric Kasischke of the University of Maryland at College Park, speaking at the American Geophysical Union conference … Read more
Tuesday was a really bad day for my carbon footprint.
First I learned that my divorce is heating up the planet. A Michigan State University study concluded that divorced couples use up more space in their respective homes, resulting in 38 million more rooms around the globe to light, heat, and cool.
Then, later in the day, as I readied to go home and light candles for the first night of Hanukkah--the Jewish Festival of Lights--I learned of the environmental implications of the annual tradition. The Jerusalem Post told of a campaign--now the topic of much blog fodder--encouraging Jews to … Read more
