New research indicates the Arctic seabed is releasing methane at a rate higher than all the other oceans of the world combined. Lester Graham reports, this recent discovery raises concerns about the pace of global warming.

Under a shallow part of the Arctic Ocean, the seafloor was thought to be permanently frozen, capping vast stores of methane underneath. Researchers at the University of Alaska Fairbanks have found that frozen cap is beginning to leak large amounts of methane into the atmosphere. Natalia Shakhova is one of the leaders of a team that’s been studying the permafrost under the Arctic Ocean.

“What we’re having now, it’s up to ten-million ton[s] of methane annually escaping from this seabed. That means that permafrost does not serve as an impermeable cap to prevent these leakages any longer.”

Methane is a greenhouse gas 30 times more potent than carbon dioxide. The greatest concern about methane releases had been the permafrost on land… but this underwater release could mean climate changes could accelerate.

The Obama Administration’s
release of money for higher
speed rail ended up being less
than most states wanted. Lester
Graham reports on what this
will mean for passenger train
service:

Eight billion dollars apparently doesn’t go that far in rail projects. The pundits have noted California’s Sacramento to San Diego corridor got 2.3 billion and Florida’s Tampa to Orlando route got 1.25 billion, making those states the big winners.

But if you forget state boundaries and look at rail networks, the Midwest’s Chicago Hub network pulled in a whopping 2.6 billion to improve the rails.

Amtrak doesn’t get any of this money. It just runs the trains. It doesn’t own many of the tracks. But spokesman Steve Kulm says better tracks mean Amtrak trains can go faster.

“Train speeds are going to increase from say 79 to 90 or from 90 to 110. But wit this funding that was announced, there was the Florida project and the California project. If those projects do happen and get moving, those projects will be at the 150 or higher levels.”

That’s how fast the train from Washington to New York goes and it’s getting more passengers than the airlines.

High-Speed Rail Money Slow

Today, August 24, is a deadline for
states competing for eight billion
dollars in federal stimulus money
for higher speed rail. Shawn Allee reports, this stimulus could
run in slow-motion:

Federal Railroad Administration staff are staying late tonight – August 24 – to accept hundreds of applications for higher-speed rail funds.

FRA spokesperson Rob Kulat says the agency wants to give out stimulus money quickly, but, just in case, it’s announced there might be two rounds of applications – not just one.

“It would be a delay, but the idea is to have successful projects, to have them work cost-effectively. If a state isn’t ready financially or technically to implement their plan, then they need to go back to the drawing board a bit. We’re not going to throw good money after bad.”

Kulat says some states have shovel-ready rail projects, but others states are just in the planning stage.

It could be years before they clear the track for faster trains.

Investors Driving Up Food Prices?

The price of food is going up and some
members of Congress want to know why. The Senate
recently held hearings on whether investors in
the commodities market are artificially inflating
prices. Mark Brush has more:

Big investors are moving money out of stocks and other investments and into
commodities.

In the last five years, the amount of money in commodities markets has
increased 20 fold. And there’s a theory that these investors are driving up food and gas
prices.

Timothy Wood says that’s not so. He’s the editor of ResourceInvestor.com.

Instead, he
says you’re paying more mostly because the dollar is worth a lot less these days. He also
says Congressional mandates to turn corn into fuel are driving up corn prices.

“When corn is so much a part of the American food chain, and the global food chain, it is
just a complete and utter farce that this has gone and been legislated.”

Wood says Congress should let the markets sort themselves out. But some members of
Congress wonder if big investors in commodities are getting rich at the expense of
families.
