Farmers markets are growing, but farmers’ incomes are not

She's not getting rich.

It's National Agriculture Day! What an appropriate day to celebrate the awesome work of our nation's farmers! The awesome work they are so crappily compensated for, that is.

They may seem to be raking in the cash at all those new local farmers markets, but America's food-growers -- those producing fruits and veg, not soy and corn -- aren't having an easy go of it. NPR's All Things Considered reports:

The market for locally grown food has seen dramatic growth over the last decade. Despite this boost in sales and popularity, evidence suggests that the economics behind the movement still don't favor the farmer. The U.S. Department of Agriculture has new programs to try to prop up small-scale operations, but many local farms only survive because they scrape by on below-market wages, or by doing without things like insurance.

Summer rains in Southwest arriving late because of climate change

These dark clouds will be coming later and later.

As if the parched Southwestern U.S. didn't have enough problems already, here's another one.

The quenching storms that take the edge off the scorching heat near parts of the U.S.-Mexico border during the hottest months are arriving later than they used to. New research indicates that climate change could push their arrival back nearly until the fall by the end of the century.

That's because it's becoming more difficult for rain-forming clouds to materialize until the atmosphere becomes saturated later in the summer season, when the skies finally explode in rainstorms over parts of Arizona, New Mexico, Texas, and northwestern Mexico.

The fallout from a substantially delayed monsoon season, which is predicted in a new study published in the Journal of Geophysical Research, could include crop failures and increasingly uncomfortable summers.

Natural-gas liquid is gushing near a Colorado creek, and nobody can figure out how to stop it

Officials in Parachute, Colo., have stopped the flow of creek-water into their reservoir in case of contamination from a mystery oil spill.

Parachute, Colo., near where a hydrocarbon spill potentially threatens water supplies.

An unidentified “liquid natural-gas product” is flowing freely into the shallow ground near a creekside gas processing plant in rural western Colorado. After 11 days of cleanup operations and investigations, the source and precise contents of the toxic spill remain a mystery.

Officials at Williams Energy, the presumed culprit in the spill, have not been able to locate the source of the leak, so they have been unable to staunch the flow of underground pollution that is threatening to contaminate Parachute Creek.

More than 60,000 gallons of hydrocarbon gunk have so far been sucked up using vacuum-equipped trucks. The underground pollution plume is believed to have grown to at least 200 feet by 170 feet and is at least 14 feet deep.


Researchers find that ‘wind turbine syndrome’ is bogus

A windfarm in South Australia
Watch out, they're coming to get you. Or are they?

South Australian cattle farmer David Mortimer allowed wind turbines to be built on his property in 2004. Now he says the turbines have made him ill.

"Mostly I've had sleep-related problems," Mortimer told The Guardian. "At night I get a deep rumbling sensation in my head which makes it hard to get to sleep. I also get a pulsing in my heart that does not correlate to my heartbeat. It gives me an acute sense of anxiety and arrhythmia that goes on for days."

Are the wind turbines making Mortimer sick? Or has he been fooled by anti-wind activists into thinking that he is sick?

Simon Chapman, a professor of public health at Sydney University, says it's the latter. He led a team of four scientists that concluded that ailments afflicting some people who live near wind farms -- often described as "wind turbine syndrome" or "vibro-acoustic disease" -- are merely "communicated diseases."


America’s infrastructure grade improves to a still very sad D+

America is full of potholes, slumping levees, and fraying electrical grids. So it may surprise you to learn that the country's physical infrastructure is actually apparently improving.

For the first time in 15 years, the American Society of Civil Engineers gave the country's infrastructure a higher grade than it did last time. Congrats, America, you've improved from a D to a D+! Soo you'll still have to repeat the class.


The New York Times reports:

Some connected trends have led to the shift, according to the engineering organization. It cited a rise in the private financing of public projects and renewed attention from state and local government to kick-start their own projects, rather than wait for Washington to send money. The jump in private investment was instrumental, for example, in the improved outlook for the nation’s rails, according to the report. That evaluation jumped to a C+ from a C-. The group also cited short-term increases in financing — a reference to President Obama’s economic stimulus package, which focused in part on “shovel-ready” projects like road and bridge repair.

“When investments are made and projects move forward, the grades rise,” the report stated.

Gregory E. DiLoreto, the group’s president, said, “A D+ is simply unacceptable for anyone serious about strengthening our nation’s economy,” but he added that the improvement “shows that this problem can be solved.”

In addition to the overall grade, ASCE handed out individual marks for specific kinds of infrastructure: near-failing D- grades for levees and inland waterways, and D grades for drinking water, hazardous waste, roads, transit, and wastewater, among others.


Green tech incubator Greenstart ups its game

We'd all like to accelerate cool green tech, but maybe the initial acceleration is less important than the distance traveled.

At least that's what Greenstart, which Grist profiled back in October, seems to be thinking as it retools its business plan: No longer an accelerator, Greenstart will essentially become a venture capital endeavor, with a focus on helping companies through multiple stages of their development instead of just shoving them off a cliff with bags of money.

"This change was 100 percent motivated by listening to our startups," writes founder and managing partner Mitch Lowe in a post today very effectively titled "We Killed Our Accelerator."

Fast Co.Exist reports:

This week, Greenstart announced that it’s shutting down its three-month accelerator program -- and morphing into a combination early-stage venture capital firm and design studio. What happened?

"It was simply because entrepreneurs were saying loud and clear that 90 days is nice but we want a partner for the life of our company," says Mitch Lowe, managing partner at Greenstart. "You just get to the good stuff at 90 days. You’re starting to add real value."

Greenstart will now be writing even fatter checks to its portfolio companies, funneling $250,000 to $500,000 into about a dozen startups each year. And those companies won't just be incubated -- Greenstart is in it for the long haul.


A cool new way climate change is killing bivalves

We already know that carbon-dioxide-filled, acidic ocean water is no-good, very-bad news for mussels and other underwater shelled creatures, causing their shells to dissolve. But, as these things so often go, it turns out that climate change is even worse for bivalves than we thought: It's unleashing an awkward kind of anti-puberty on them. They're growing smaller and weaker, and now we find out that they're basically losing their hair.


New research published in the journal Nature shows that mussels' proteinaceuous byssal threads -- the little stringy bits that allow them to stick their bodies on stuff -- are particularly susceptible to ocean acidification. The researchers found mussels' little stringy bits were 40 percent weaker when exposed to elevated CO2 levels, even when their shell strength and tissue growth weren't affected.

Colorado wildfires get an early start this dry year

Colorado on fire in 2012.

An early start to wildfire season took northern Colorado residents by surprise late last week. Two fires broke out on Friday, fanned by unusually high temperatures, low humidity, and strong winds, which forced hundreds of people to evacuate their homes. And the state has been suffering from epic, epic drought, so that’s really helping with the burning.

Reuters reports:

The early-season wildfires could be a bad omen for drought-stricken Colorado, which had one of its worst ever wildfire seasons in 2012.

All of Colorado is experiencing moderate to exceptional drought conditions, according to the U.S. Drought Monitor.

Snowpack levels in the Colorado mountains are below the annual average. The state's high-population urban corridor and farmers on the eastern plains rely on melting mountain snow for drinking water and irrigation.

As local fire captain Patrick Love told the Los Angeles Times, "the drought that we have been in, in this portion of the state, has somewhat played a role in the dryness of all the fuels.”


Fastest-growing metro areas in U.S. are sprawling and water-challenged

Yep, New York grew too, but not nearly as much as Texas.
New York grew too, but not as much as big metro areas in Texas.

It's time again for another fun-filled Census report on how much bigger U.S. cities are getting! Happy Monday, Southern and Western states: Y'all dominated the top 30 winning metropolitan areas, crushing the Midwest and Eastern seaboard.

"While most metro areas didn’t experience significant swings in population over the past year, several in the Sun Belt and Mountain West saw noticeable gains," the Governing blog reports.

Here's the thing about these Census city growth reports, though: While we at Grist like to celebrate cities, the Census doesn't calculate urban growth. The agency looks at total metropolitan-area growth, which includes suburbs and sometimes even exurbs. And it turns out that many of the fastest-growing metros are among the sprawlingest and least sustainable.

The top three metro winners for population growth from July 2011 to July 2012, according to the Census, were car-dependent areas with water problems: Dallas-Fort Worth-Arlington, Texas; Houston-the Woodlands-Sugar Land, Texas; and Los Angeles-Long Beach-Anaheim, Calif. Shouldn't-even-exist Phoenix, Ariz., is No. 7 for big growth; Las Vegas, Nev., is No. 20. City growth is great, but not when it's really sprawl, which is what happens most of the time when metro areas expand.

Louisiana pipeline fire, now extinguished, sickened residents

The fire on Friday, three days after a tug boat and pipeline ignited in Louisiana

The fire on Friday, three days after a tug boat and pipeline ignited in Louisiana.

Air pollution from a huge pipeline and tug boat fire, which raged 30 miles south of New Orleans from Tuesday until it was extinguished on Friday, sickened nearby residents with respiratory ailments and other conditions.

Two days after the fire ignited, the Louisiana Bucket Brigade went door-to-door in LaFitte, La., just east of the bayou where the accident happened, and found that one out of every 10 residents surveyed suffered breathing difficulty, sore eyes, headaches, or other health problems triggered by the acrid pollution plume. About twice that number reported smelling the smoke, and nearly two-thirds said they saw the smoke or fire. "I have bronchial asthma, and I couldn't breathe very well," one resident told the nonprofit.

Health problems could have been far worse had northerly winds not blown the smoke away from the tiny Jefferson Parish community.
