Vice President Joe Biden told an activist on Friday that he doesn't support the proposed Keystone XL pipeline, according to a post on the Sierra Club website.

While the veep was working the crowd at an event in South Carolina, Elaine Cooper got a moment with him:

I asked him about the administration’s commitment to making progress on climate and whether the president would reject the pipeline. He looked at the Sierra Club hat on my head, and he said “yes, I do -- I share your views -- but I am in the minority,” and he smiled. ...

I know that this vice president is a man who isn’t afraid to speak from his heart, and who sometimes gets out in front of the rest of the administration on moral issues. It was nearly a year before, on May 6, 2012, that Biden said that he was “absolutely comfortable” with marriage equality. What the vice president said to me on Friday was equally brave and equally right.

Environmental leaders seized on the news, BuzzFeed reports:

Last summer, a leaky tank led to the shutdown of the Palisades nuclear power plant in Michigan. So plant owner Entergy patched up the leak, fired back up the reactor, and hoped for the best.

Unfortunately, the best did not materialize.

The tank began leaking again. But no worries, thought the Einsteins at Entergy, it was only leaking a gallon a day. That was OK, they figured, because the NRC had allowed it to leak up to 38 gallons a day. As of Friday, they were still doing that whole "hoping for the best" thing.

But on Saturday the leaky drip turned into a gush, and all the hoping in the world couldn't hold back the tide of spilling radioactive water. Nearly 80 gallons of water containing small amounts of radioactive tritium and possibly trace amounts of cobalt and cesium spewed into Lake Michigan, the Nuclear Regulatory Commission told the AP.

It looks like Pacific Gas & Electric's shareholders are going to have to spend $2.25 billion on safety improvements because of a 2010 natural-gas pipeline explosion in the San Francisco exurb of San Bruno.

That was the record-breaking penalty proposed this week by staff of the California Public Utilities Commission. The agency's five commissioners will have the final say on the proposal, and PG&E will have an opportunity to try to barter down that price tag. The company says it has already spent more than $1 billion on improvements since the fatal accident.

The penalty is being characterized by the agency and media reports as a "fine," but while fines are typically paid into general government coffers, this $2.25 billion would be invested fully in improving the safety of PG&E's infrastructure. And the money would need to come out of shareholder profits; it couldn't be gouged from customers by hiking their bills.

It's great to go green and it's laudable to go local. But don't you dare try to do both at once.

That's the message the World Trade Organization sent this week went it ruled -- again -- that Ontario’s Green Energy Act illegally discriminated against international renewable energy companies. Similar green jobs programs in other countries might also have to be disbanded following the ruling.

The Green Energy Act aims to reduce greenhouse gas emissions while encouraging energy conservation and fostering a jobs-rich renewable energy sector. Under the controversial elements of the act, electricity suppliers could charge premium prices for clean energy, but only if they produced that electricity using a certain amount of locally manufactured equipment like solar panels.

The European Union and Japan protested to the international trade body, claiming that the program illegally discriminated against their manufacturers. The WTO sided with the E.U. and Japan in a November ruling. Ontario appealed against that ruling, and on Monday the WTO rejected the appeal [PDF] while making some minor tweaks to its earlier ruling. From the Toronto Star:

Uber-conservative Beltway newspaper The Washington Examiner has revealed its secret crush on Barack Obama and his administration's fracker-friendly ways.

It's not often that the newspaper says anything nice about the president. The Examiner is owned by Philip Anschutz, an oil-drilling magnate, and the newspaper sometimes seems to exist only to beam its owner's conservative views into the brains of D.C. insiders.

In March, for example, the paper's editorial writers likened the president to "a desperate gambler who doubles down on a losing bet" after he called for more green energy spending. In January, the editorial writers charged that "Obamacare threatens states' fiscal autonomy." And, famously, back in 2009, Examiner political correspondent Byron York argued that Obama's "sky-high ratings among African-Americans make some of his positions appear a bit more popular overall than they actually are" -- as if the opinions of blacks shouldn't count.

But when it comes to the Obama administration's complicity in the nationwide fracking spree, the Examiner has nothing but love. Here are some excerpts from "Two cheers for Obama on fracking," the newspaper's May 5 editorial:

On Tuesday, voters in Youngstown, Ohio, gave the fracking industry carte blanche to continue pumping chemicals into the ground beneath them and pumping natural gas out.

A city charter amendment that would have outlawed hydraulic fracturing in the city was rejected by voters, with the unofficial final vote tally showing 3,821 votes against and 2,880 in favor. The ballot measure would also have banned new pipelines in the city and prevented oil-field waste from being transported through the city.

A fracking boom is underway in Ohio, especially in its east, where Youngstown is located. But the boom has not brought with it many jobs for Ohioans, despite promises otherwise, as most of the work is being done by specialists who've come in from other states. It has, however, brought with it water pollution problems.

Opposition to the ballot measure was spearheaded by a business-backed group calling itself Mahoning Valley Coalition for Job Growth and Investment. That group was formed especially to defeat the ballot measure, and it easily outspent the measure's backers. In campaigning, the business group had described the ballot measure as unconstitutional, far-reaching, and unenforceable, and claimed it would send the wrong kind of message to the business community.

The drought that parched much of the nation during the past year didn't just stunt crops -- it also stunted the annual yield of tornadoes. And an unseasonably chilly spring is so far helping to keep the hellish twisters at bay -- although weather forecasters warn that trend may be short-lived.

During the past 12 months, the U.S. was hit by an estimated 197 tornadoes rated EF1 or stronger on the Enhanced Fujita scale, which ranks tornadoes according to their destructive potential from a low "0" up to a devastating "5." That was the lowest number of such tornadoes during any 12-month period since record-keeping began in 1954 -- well below the previous low of 247 recorded between July 1990 and June 1991.

That's in huge contrast to the onslaught of tornadoes that tore deadly paths of destruction through the nation in 2011, which was a record-busting year of tornadoes galore.

Back in high school, I had a great strategy for dealing with parking tickets I couldn’t afford to pay: I went down to city hall and challenged them -- sometimes with a legitimate excuse, sometimes not (“The two-hour sign was obscured by a flowering cherry tree!”). I had figured out that bureaucrats cared less about the reliability of my sob story than they did about getting on with their day, so often they’d just roll their eyes, reduce the fine, and shoo me out the door.

Turns out the same tactic works for coal companies facing fines for safety infractions. A Cleveland Plain Dealer investigation found that when federal regulators fine mine operators for violating safety standards, those companies “are fighting significant fines as a matter of course and getting them reduced, if not dropped,” which means “clogging up the appeals process and wearing down a system that lacks resources to match the challenge.” You know, just like a privileged teenager exploiting an overburdened traffic court -- except with hundreds of thousands of dollars, not to mention miners’ lives, at stake.

The Plain Dealer reports:

If you want to a kill a honeybee hive's buzz, take all its honey away and feed the bees a steady diet of high-fructose corn syrup.

Believe it or not, apiarists have been doing just that since the 1970s -- feeding HFCS to their colonies as a replacement source of nourishment for the honey that gets taken away from them to be sold.

And believe it or not, HFCS, which is bad for humans, is also bad for honeybees. It's especially bad for those that are exposed to pesticides, which these days is a high proportion of them.

It's not that HFCS contributes to honeybee diabetes, nor does it result in honeybee obesity. But it weakens their defenses. And right now, the bees need all the defenses they can get in order to survive.

When honeybees collect nectar from flowers, they also gather pollen and a substance called propolis, which they use to make waxy honeycombs. The pollen and propolis are loaded with three types of compounds that University of Illinois entomologists discovered can help the bees detoxify their cells and protect themselves from pesticides and microbes.

California's governor was quick to blame climate change for the early-season wildfires that are already wreaking havoc in his state.

Gov. Jerry Brown (D) has been an advocate for climate action and a fiery critic of climate deniers. On Monday, he visited the state fire department's aviation management unit as firefighters battled the remains of what a couple days earlier had been a raging blaze in the Santa Monica Mountains. While he was there, he shared some choice words with reporters about the causes and consequences of a fire season that's shaping up to be a big one. From the Los Angeles Times:
