Cures for congestion can come cheap

When I was a little kid, I remember being stuck in gridlock on I-5. (Seattle had congested freeways even back in the 1970s, shocking as that sounds.) And I remember being perplexed that all the cars would slow down in heavy traffic. Instead of spacing out so far, I wondered, why couldn't they all just maintain 55 miles per hour and drive inches apart. As long as everyone agreed to drive the same speed and not hit the brakes, heavy traffic wouldn't require us to slow down. Right?

My parents didn't get it. Typical parents.

Cheap coal and $100 oil

Amid vague talk of how $100/barrel oil might represent a kind of sea change, inspiring corporations and individuals to lower their carbon footprints, the smart money is betting on another direction: the burning of more coal. That’s a harrowing trend. As NASA climatologist James Hanson recently put it: Coal will determine whether we continue to […]

For every 1 degree Celsius globe warms, some 21,000 people could die, says study

For every 1 degree Celsius of anthropogenic global warming, some 21,000 people worldwide could die, including more than 1,000 in the U.S., says a new study in Geophysical Research Letters. According to computer modeling by researcher Mark Jacobson, increased air pollution due to rising carbon-dioxide levels will lead to more fatalities. “This is a cause […]

New study says trees are absorbing less CO2 than predicted

Forests have gained a lot of attention in the climate change conversation because of their ability to suck carbon out of the atmosphere. Individuals can buy "reforestation" offsets on the internet. There's talk of including credits for carbon stored in trees and wood products as part of many proposed cap-and-trade systems. Cities and businesses are even planting trees as part of their efforts to slow climate change. But forest ecosystems are, by their nature, unpredictable. And new research shows carbon sinks are weaker than predicted.

There's no doubt that forests, and their tremendous ability to store carbon, can play a role in protecting the climate. But we have to be cautious about that role. Forest ecosystems are, by their nature, unpredictable -- - there's simply no way to know how much carbon a forest will store over the long haul. Worse, climate change itself magnifies those uncertainties. If a warmer climate makes forest fires more frequent -- as some people believe is possible -- then a lot of "offsets" will simply go up in smoke. Or consider BC's devastating pine beetle infestation -- an example of how ecosystem disruption can fell more trees than any chainsaw.

And there's troubling news today that makes us more cautious than ever: A new global study by researchers at the University of Helsinki shows that trees are absorbing less CO2 than predicted, as the world warms and vegetation patterns shift.

Green lists from 2007

Remember when we published our Top 15 Green Stories of 2007? Literally the day before the holiday break? So no one read it? That was awesome. Now go read it. When you get back, here are a few other random greenish lists I’ve stumbled across: Plenty magazine: Plenty’s picks for top environmental stories of 2007 […]

Toshiba said to have developed mini nuclear reactor

Says Next Energy News: Toshiba has developed a new class of micro size Nuclear Reactors that is designed to power individual apartment buildings or city blocks. The new reactor, which is only 20 feet by 6 feet, could change everything for small remote communities, small businesses or even a group of neighbors who are fed […]

California stats say state emissions-reduction plan far more effective than federal law

When the U.S. EPA denied California the right to regulate greenhouse-gas emissions from vehicles, the agency reasoned that the just-passed energy bill’s boost to national fuel-economy standards would be stronger emissions-reduction policy than the state’s plan. California, which has sued, would beg to differ, and has released statistics refuting the EPA’s claim. For example: The […]

More on cap-and-trade systems

Here's a clear demonstration of why, in a cap-and-trade system, grandfathering emissions rights to historic polluters is a terrible idea:

The UK's biggest polluters will reap a windfall of at least £6bn from rising power prices and the soaring value of carbon under the new European carbon trading scheme ...

Critics argue ... that the scheme, under which nearly all allowances are granted free of charge rather than having to be bought by big polluters, has created a distorted market in which the worst offenders will enjoy bumper profits while incurring no extra underlying cost for producing greenhouse gases.

That's just about right: handing out pollution rights for free, as the European emissions trading system did, creates the potential for massive, unearned windfall profits.

Permits will have a market value -- someone will want to buy them. So when we hand out emissions permits at no cost, we're essentially handing out free money.

There may be a few exceptions to this rule: a few economic sectors where free allocation won't lead to windfall profits. But they're the exceptions. The rule (as demonstrated in Europe) is that grandfathering is great for polluters, and bad for consumers.

So maybe that's why lots of big oil and coal companies are so supportive of grandfathering ...

Climate refugees and Wi-Fi pollution

The Ecologist is such a great magazine. But I'm sorry that they don't make any of their content freely available online for me to link to here, because the Dec/Jan issue has some really important reading. For one, the world's first (human) climate refugees are about to lose their islands (in the Sunderbans Delta, which straddles the border of India and Bangladesh and is the world's largest mangrove forest, due to increased flows of water from melting glaciers in the Ganges headwaters).

There's also a meaty discussion about the possible negative health effects of Wi-Fi. Whether or not Wi-Fi microwaves actually cause headaches, sleep disturbance, depression, memory loss, and worse, as some studies claim, it is pretty remarkable -- according to a physicist interviewed for the piece -- that this technology could come to market and become ubiquitous without having to undergo safety trials or scrutiny.

With oil prices rising, Asia turns to coal

You may have heard that oil prices are flirting with $100 a barrel; what’s an oil-dependent, energy-hungry globe to do? In Asia, home to a third of the world’s proven coal reserves, the answer seems obvious. Across the continent, billions of dollars are being poured into R&D of coal-to-liquid fuel and coal-bed methane extraction. Some […]
