Bradford Plumer summarizes:

About one-quarter of the oil is still bobbing on the sea surface or washed ashore. Another quarter has been dispersed into microscopic droplets, either by artificial chemicals or natural processes. And another quarter has been “dissolved.” All told, just 25 percent has been physically removed from the Gulf ecosystem. The rest is still lurking… somewhere.

It’s good to know that much of the oil has evaporated or been dispersed. The trouble is, as Kate Sheppard notes, that there are still “about nine and a half Exxon Valdez spills” out there.

From 2000 to 2009, onshore pipeline accidents caused 2,554 major incidents, including 161 deaths and 576 injuries. Offshore, 1,443 incidents caused 41 fatalities, 302 injuries, 476 fires, and 356 releases of pollution into the waters.

Interestingly, even though transportation uses account for about 28% of our energy consumption, very little of the projected emissions reductions to be achieved under climate legislation would have come from the transportation sector. As David Roberts notes, “The reason for this is simple: It takes an extremely high price on carbon to substantially raise the price of gasoline.” Roberts:

Under the American Power Act, the ceiling on the price of a ton of carbon in 2013 is $25. Even in the unlikely event that the price hits the ceiling, that will boost the price of a gas by just under a quarter per gallon. Given that gas has swung around over a $2-3 range just in the last few years, a quarter isn’t much more than noise. A recent study at Harvard found that in order to reduce carbon emissions in the transportation sector 14 percent from 2005 levels by 2020, gas will need to rise to $7 a gallon by then. Getting there from today’s $4 gas would require a carbon price of well over $300 a ton, and that, in turn, would completely upend the utility sector. So it won’t happen.

Which is all a propos of the new “utilities-only cap-and-trade bill” trial balloon floating around Washington. Even if it’s not ideal, it sounds like a productive development in what has been looking like a politically moribund debate. Read David Roberts’ piece for more.

Is the BP disaster in the Gulf of Mexico going to wipe out the brown pelican? Not globally, at least, writes Phil McKenna at the New Scientist:

The species as a whole isn’t about to go extinct as a result of the oil spill: as 400,000 out of a total global population of 650,000 live in Peru. Roughly 60 per cent of the subspecies Pelecanus occidentalis carolinensis breed along the Gulf coast, where many nest on the barrier islands off Louisiana that have already been exposed to oil.

The slicks threaten the birds and their fragile wetland habitat only a few months after brown pelicans were removed from the US federal endangered and threatened species list in November last year. The birds had been on the list since 1970 after the pesticide DDT poisoned and nearly wiped out pelicans across the country. At the time Louisiana, where the pelican is the official state bird, lost its entire population. After years of resettling individual birds from Atlantic coast populations, Louisiana was able to boast the largest brown pelican population of any Gulf state, with 16,000 nesting pairs in 2004.

Just a small clarification: it’s true that Louisiana’s brown pelicans were just removed from the endangered list in November 2009. But the Alabama, Florida, and the Atlanta coast populations were taken off the list in 1985.

Ezra Klein writes:

So though Obama deserves to take his lumps on this one, Americans should take the lesson of recent disasters, from the financial crisis to the BP spill to Katrina, and realize that they actually like having good regulators and they get upset when their regulators fail them. Which might mean it’s a good idea to elect people who are interested in making sure regulators don’t stop doing their jobs every couple of years, as opposed to people who think that the best regulation is no regulation, and the second-best regulation is whatever the relevant industry tells them it is.

Effective government is about ends and means. It requires taking both seriously. To ensure public safety and prosperity, we need regulation adequate to those ends. Elections matter.

Here are two pictures I took with my phone this morning. Take a good look. It may be the last you’ll see of that unspoiled quartz sand.

And here’s a NASA satellite image (at a different scale and, admittedly, hard to make out):
