Sometime later this year, a yet-to-be-named guinea pig very lucky culinary pioneer will take the first bite of the first hamburger grown in a lab. At that point, the cost of making that burger will have totaled more than $331,000 (an estimated 250,000 euros). The meat will be grown from bovine stem cells that produce muscle and fat -- and if that sounds less than appetizing, keep in mind that the burger will be prepared by famed chef Heston Blumenthal.

Via the Dish, this art installation in downtown San Francisco is the ultimate tiny house. It's seven by eight by 11 feet, and it's suspended 40 feet in the air. Plus, it’s recycled AND green: It's made of 100-year-old reclaimed barn wood, and powered by off-grid solar.

Among other ideas, the project is meant to communicate "a new home front in the remaining voids of San Francisco" and "the arrogance of westward expansion," according to designboom. While we now think it's awesome and perhaps necessary to inhabit tiny spaces, for pioneers, it was just practical.

Todd Tanner will give you his gun when you pry it from his cold, convinced-of-the-nonexistence-of-climate-change hands. Tanner, the chair of the new group Conservation Hawks -- sportsmen (i.e. hunters) who don't want climate change to ruin their fun -- has challenged anyone to prove to him that climate change shouldn’t be a concern. If you win, he will give you, the Conservationist's Hal Herring reports, "his most prized possession: A Beretta Silver Pigeon 12 gauge over/under that was a gift from his wife, and has been a faithful companion on many a Montana bird hunt." (Grist List doesn’t know that much about guns but this one looks pretty much like the gun we’d want to own, if we owned a gun.)

Lest deniers think the man is joking, Herring assures us, "I know the gun, and I’ve hunted and fished with Todd for years. He’s not kidding. You convince him, he’ll give you the gun."

Yesterday evening, water researcher and Pacific Institute Director Peter Gleick came forward to say that it was he who had first obtained the documents revealing the inner workings of the climate-denying Heartland Institute. Gleick admitted that he had obtained most of the documents using a false identity. This morning, the climate community has exploded with judgments, positive and negative, of Gleick's actions. Was he Goofus or Gallant? Here's a sampling of arguments on either side.

First, Gleick's own assessment of his decision. In his post, he called it "a serious lapse of my own and professional judgment and ethics." He also apologized "to all those affected."

Heartland, of course, isn't about to praise his actions. The institute's president wrote to reporters that "Gleick’s crime was a serious one … A mere apology is not enough to undo the damage.” (We know political hypocrisy is getting so commonplace as to be boring, so we’ll just say “cough cough Climategate.”)

Plenty of climate thinkers jumped to Gleick's defense, though.

Peter Gleick, a water expert and climate scientist, says he obtained documents that revealed the inner workings of the Heartland Institute by soliciting them from the group under someone else's name.

A new study says that exploiting Canada's tar sands might not exacerbate climate change as much as environmental groups fear.

Mexico and the U.S. are going to work together on offshore oil drilling.

Public lands belong to all of us, so when the federal government decides to lease them out to oil and gas drillers, those companies have to pay for depriving taxpayers of environmental and recreational benefits. And the Obama administration has decided that they're not paying enough. So the Interior Department's budget includes a proposal to raise royalties for oil and gas projects by 50 percent.

The House passed a bill expanding oil drilling in ANWR and oil shale drilling. Revenues are meant to fund the transportation bill, which won't be considered until after the President's Day recess.

Mexico City shut down a giant landfill, but will capture methane that the landfill exudes and use it as a power source.

A new technique could turn grass into plastic.

Secretary of State Hillary Clinton, along with EPA's Lisa Jackson and a handful of international diplomats, has had enough of climate inaction. She announced a new initiative Thursday morning to start attacking "short-lived climate pollutants" -- otherwise known as "everything except carbon dioxide." Recent research has shown that decreasing these pollutants, which include methane, soot, and HFCs, could actually pull back climate change by as much as 0.9 degrees F. That won't solve the problem, but it could buy the world some time while diplomats continue squabbling over carbon.

There's also a win-win-win angle to attacking pollutants like soot and methane.

The State Department is going to announce this morning a program to reduce shorter-lived greenhouse gases, like methane.

The House won't vote on Republicans' transportation bill of horrors quite yet.

Mining in Mongolia -- good for China, maybe not the best idea for the desert environment or the people who live there, who are mostly herders.
