The decline of honey bees has been a major concern globally for the past decade. One of the factors that could be contributing to the decline is the use of insecticides — specifically neonicotinoids — that persist in rivers and streams. Researchers now report in the ACS journal Environmental Science & Technology Letters that although sunlight plays an important role in degrading pollutants, its effects on neonicotinoids can diminish dramatically even in shallow water.
Neonicotinoids protect crops from pests, such as whiteflies, beetles and termites. They are a popular tool in a farmer’s arsenal, but they end up washing into surface waters and soil. Some research has suggested the insecticides play a role in the disappearance of bees, a phenomenon known as colony collapse disorder. But scientists didn’t fully understand the fate of neonicotinoids in the environment, an important factor in determining how they might contribute to the disorder. Charles S. Wong and colleagues wanted to investigate sunlight’s effects on these insecticides in water.
Out of five neonicotinoids the researchers tested in water under simulated sunny conditions, three degraded considerably within minutes.
Two took a few days to break down. But a depth of just 3 inches of water was enough to shield at least one, thiamethoxam, from the degrading effects of the sun. The researchers say that this persistence at shallow depths could increase the chances aquatic life and other wildlife, including bees, could get exposed to the insecticide.
How many agribusiness/farm lobbies did you ever hear of that spend time lobbying for clean water – after it’s outbound from the fields just irrigated?

MEXICO CITY — On a sweaty May morning in this sprawling mountain capital, residents heard a painfully familiar warning on the radio and TV.
Air pollution was at dangerous levels, environmental authorities said. People were advised to stay indoors as much as possible and avoid exercise. Asthma sufferers should take particular care.
On the city streets, this pollution could be seen in dirty clouds hanging amid grid-locked traffic.
The “environmental pre-contingency” on May 9 was the fourth so far this year, compared to three in all of 2014. The warnings are a reminder of the long uphill battle against dirty air in North America’s largest city — which has been a laboratory for pollution in megacities around the planet.
This rise comes after years in which Mexico City air has been getting cleaner, thanks to concerted campaigns. But while some problems have been resolved, others appear.
One issue is that Mexico is getting steadily hotter, apparently due to global warming. Last year was the hottest in Mexico since records began, with average temperatures of 71.78 degrees Fahrenheit.
Higher temperatures mean that pollutants release faster into the air…
By 2010, when Mexico City hosted a UN climate change conference, it was hailed as a poster child for anti-pollution measures. Lead in the air had dropped by 90 percent over two decades, environmental authorities reported.
Yet despite the giant steps, pollution persists and is exacerbated by new problems, including the rising temperatures…
While cars have gotten cleaner they have also gotten more numerous. There are now 275 cars per 1,000 people in Mexico, according to the World Bank. In the Mexico City urban sprawl with 20 million residents, this would mean about 5.5 million automobiles.
“Air is very democratic,” Jose Agustin Garcia of Mexico’s Center for Atmosphere Science says. “The same air goes into rich and poor neighborhoods alike.”
Of course, scumbags like the Koch Bros and their Mexican equivalents can afford to live anywhere. They can manage their polluted empires from a resort or their favorite palacio in another country altogether.
People are one of the cheapest component of their corporate profits.
Dead zones in the Atlantic — so called because their lack of oxygen can’t sustain life — have been seen for the first time by scientists.
These areas of extremely low oxygen occurred in the tropical North Atlantic. The levels of oxygen were the lowest ever recorded in the open Atlantic. And while some microorganisms can live in these zones, most sea life can’t, which could lead to massive fish kills…
The oxygen levels found in the open North Atlantic had about 1/2 the concentrations scientists expected to see, lead-author Johannes Karstensen said…
Most dead zones are found near inhabited coastlines, after rivers carry fertilizers and other chemicals that cause algae blooms. When the algae die, they’re decomposed by bacteria that take up the oxygen.
The Atlantic dead zones, by contrast, appear to form in large (60 to 100 miles) eddies, “with the dead zone taking up the upper 100 meters or so,” explains Karstensen, a researcher at GEOMAR, the Helmholtz Centre for Ocean Research Kiel, in Kiel, Germany.
“The fast rotation of the eddies makes it very difficult to exchange oxygen across the boundary between the rotating current and the surrounding ocean. Moreover, the circulation creates a very shallow layer — of a few tens of meters — on top of the swirling water that supports intense plant growth similar to coastal algae blooms,” Karstensen said. “From our measurements, we estimated that the oxygen consumption within the eddies is some five times larger than in normal ocean conditions.”
“Given that the few dead zones we observed propagated less than 100 kilometers north of the Cape Verde archipelago, it is not unlikely that an open-ocean dead zone will hit the islands at some point. This could cause the coast to be flooded with low-oxygen water, which may put severe stress on the coastal ecosystems and may even provoke fish kills and the die-off of other marine life.”
But, hey, as long as there’s sufficient cheap labor available from the local unemployed to clean the hulls of every Cruise Line skyscraper pulling into souvenir harbors – why worry?
The Obama administration said Friday it is requiring companies that drill for oil and natural gas on federal lands to disclose chemicals used in hydraulic fracturing operations.
A rule to take effect in June also updates requirements for well construction and disposal of water and other fluids used in fracking, a drilling method that has prompted an ongoing boom in natural gas production.
The rule has been under consideration for more than three years, drawing criticism from the oil and gas industry and environmental groups. The industry fears the regulation could hinder the drilling boom, while some environmental groups worry that it could allow unsafe drilling techniques to pollute groundwater.
What crap writing/editing. It’s the absence of regulations that allows unsafe drilling techniques to pollute groundwater.
The final rule hews closely to a draft that has lingered since the Obama administration proposed it in May 2013. The rule relies on an online database used by at least 16 states to track the chemicals used in fracking operations. The website, FracFocus.org, was formed by industry and intergovernmental groups in 2011 and allows users to gather well-specific data on tens of thousands of drilling sites across the country.
Companies will have to disclose the chemicals they use within 30 days of the fracking operation.
While the new rule only applies to federal land – which makes up just one-tenth of natural gas drilling in the United States – the Obama administration is hoping the rule will serve as a model and set a new standard for hydraulic fracturing that states and other regulators will follow.
Brian Deese, a senior adviser to President Barack Obama, said…“Ultimately, this is an issue that is going to be decided in state capitals and localities as well as with the industry,” he said…
Thomas Pyle, president of the pro-industry Institute for Energy Research, said blah, blah, blah.
The League of Conservation Voters called the bill an important step forward to regulate fracking.
Even so, the group was disappointed with the continued reliance on FracFocus, which a spokeswoman described as an industry-run website.
Participation in FracFocus is voluntarily. So, the creeps using deleterious chemicals simply don’t participate.
FracFocus, right now, displays info on fewer than 95,000 oil and gas wells. The industry admits to approximately 441,000 fracked gas wells alone.
After three years of introspection, investigation and time-wasting the White House proposes tightening of regulations based on info from a single voluntary website. No requirements for compliance. And the regulations only apply to federal lands.
The rest is left in the hands of state legislatures who will use their God-given states rights – and motivational handouts from oil and gas lobbyists – to do absolutely nothing.
Bridger LLC – “We are committed to environmetal stewardship”
Bridger Pipeline LLC said on Monday it has shut the 42,000 barrel per day Poplar pipeline system after a weekend breach that sent as much as 1,200 barrels of crude oil into the Yellowstone River near Glendive, Montana.
The company said crews are now cleaning up the site after the leak on Saturday morning. Bridger estimates between 300 and 1,200 barrels spilled but could not say how much of the light crude flowed into the river.
The pipeline system runs from the Canadian border to Baker, Montana, where it meets the Butte pipeline. The Poplar system gathers crude from Bakken producers in eastern Montana and North Dakota. The company cannot yet say when the line will reopen or what caused the leak…
The spill is the second in the river in recent years. In 2011, Exxon Mobil Corp’s 40,000 bpd Silvertip pipeline in Montana ruptured underneath the river, releasing more than 1,000 barrels of crude and costing the company about $135 million to clean up…
Yup. The Yellowatone is a lovely river to fish. When you’re not concerned if the oil coating the fish is something other than olive oil.
When Reuters rolled out this article at 4:13 EST, they said no municipalities reported any problems with their water supplies. Well – the EPA has now shut down the water supply system for the town of Glendive, There is oil pollution in that system,, Federal, state and local agencies are working to secure a separate clean water supply for residents until the system can be flushed – and clean water from the river is available.
The screen shot at the top is from Bridger’s website. No mention of any oil spill in the Yellowstone River,

The new year has only just begun, but we’ve already recorded our first days with average carbon dioxide levels above 400 parts per million, potentially leading to many months in a row above this threshold, experts say.
The Scripps Institution of Oceanography records of atmospheric carbon dioxide levels show that Jan. 1 was the first day of the new year above that concentration, followed by Jan. 3 and Jan. 7. Daily averages have continued at this level or higher through Jan. 9, though they could continue to dance up and down around that mark due to day-to-day variations caused by weather systems. But even with those fluctuations, 2015 will likely see many months above 400 ppm, possibly starting with the very first month of the year…
The 400 ppm mark was first passed on May 9, 2013. In 2014, it happened two months earlier, in March. The average CO2 concentrations for March, April and June 2014 were all above 400 ppm, the first time that has been recorded. The peak CO2 measurement of 2014 was just shy of 402 ppm in May.
While the 400 ppm mark is somewhat symbolic (as the increase in warming between 399 ppm and 400 ppm is small), it is a large increase from pre-industrial CO2 concentrations, which were around 280 ppm. The progressively earlier occurrence of these high CO2 levels — not seen in somewhere between 800,000 and 15 million years — points to the inexorable buildup of heat-trapping gas in the atmosphere as human emissions continue unabated.
That increase in CO2 and other greenhouse gases has raised Earth’s average temperature by 1.6°F since the beginning of the 20th century. Some scientists say that to avoid the worst consequences of climate change, that warming needs to stay under 2°C, or 3.6°F…
The world’s plants can only pull so much CO2 out of the atmosphere in a given season, while human emissions keep rising. This is leaving an excess of about 2 ppm of CO2 in the atmosphere every year, meaning the 400 ppm mark will keep occurring earlier and earlier. In just a year or two, carbon dioxide levels will likely be about 400 ppm year-round.
But, hey, Congressional Republicans, Tea Party Know-Nothings and other intellectual failures keep telling the world, “Don’t Worry, Be Happy!” Corporate profits are up. The four or five biggest banks in America need new wheelbarrows to truck their cash around.
And nothing else matters.
More than 11,000 oil wells have been drilled in North Dakota since 2006, covering the state’s agricultural landscape. In all, almost 40,000 miles of well bores have been drilled underground to connect the fracking operations to surface wells. Laid end to end, they would circle the Earth about one and a half times.
On Sunday, The New York Times published a monthslong investigation by Deborah Sontag and Robert Gebeloff into North Dakota’s conflicted relationship with its booming oil industry. In the process of reporting that article, we obtained the locations of every oil drilling line of every well in the state.
The precise depths and directions of these remain out of sight for a very obvious reason: The drilling lines are underground. Here, we change that.
The illustrations shown here are accurate in every respect except one: We changed the vertical direction of each oil well bore to go above ground instead of below it. Otherwise, every bore line is shown precisely how it’s described by North Dakota’s Department of Mineral Resources.
Makes you feel all warm and fuzzy over lowered gasoline prices we’re all getting to enjoy. Why worry about air pollution when you can get in your car and drive to every sale in every brick-and-mortar store in your county over the weekend?
However – given my personal experience working for some of these profit-hungry creeps now awash in dollars as much as they are in oil – I could drive you into North Dakota blindfolded. And with the windows open in my pickup, you could tell when we were entering that oil field by the smell of what used to be clean air.
Thanks, Ursarodinia, for the reminder
About 15 train tanker cars carrying crude oil derailed Wednesday afternoon in Lynchburg, Va., plunging several of them into the James River, sparking a massive fire and spilling oil.
The derailment prompted evacuations in the downtown district near the railway for hours until the massive fire that spewed black, acrid smoke was extinguished. There were no reports of injuries or damage to nearby buildings.
Downstream more than 100 miles, a spokeswoman for the city of Richmond said utility officials stopped capturing water from the river as a precaution until the extent of environmental damage caused by the oil spill became clear. Instead, Richmond is relying on a backup canal for water…
CSX Transportation, which operated the Chicago-to-Virginia freight train, said the fire erupted from three punctured cars after the 2:30 p.m. derailment. In a statement, the company said it was sending safety and environmental experts to the scene…
Wednesday’s fire is the latest in a series involving trains carrying crude oil as the nation’s drilling boom fuels a surge in oil transportation. Fearful of seeing similar accidents in their own jurisdictions, some officials have called for tougher safety regulations for freight train operators.
A significant portion of the oil-carrying rolling stock on US railroads is about as out-of-date as the ideology of politicians who fight 24/7 against modernizing our railroad system. I’m not certain why they hate railroads so much. They certainly don’t give a damn about people killed or the pollution of environments around North America as a result of their idjit mentality.
Not that the owners of railway companies are spending much – yet – on updating the ancient tankers they’re using to haul boomtown oil from the Dakotas and elsewhere.
Somewhere around two hundred thousand years ago, a new primate emerges on Earth.
“The members of the species are not particularly swift or strong or fertile,” the New Yorker’s Elizabeth Kolbert writes in her new book, “The Sixth Extinction: An Unnatural History.” “They are, however, singularly resourceful.”
It is, of course, us — big-brained, small-browed genetic mutants clever enough to outcompete animals ten times our size and gradually fan out across the globe.
Eventually, humankind invents axes, engines, cities and strip malls. We tear down forests and dig up fuel from the ground.
Other times we excavate out of curiosity, traveling backward in time through the records of bones, fossils and rocks that eventually give up clues to mass tragedies in the ancient past. Huge portions of the world’s creatures disappeared in a geologic blink of the eye.
In fact, five blinks — so far. The reasons aren’t always settled in science, but strong possibilities for the various mass extinctions include a dramatic release of carbon dioxide in the atmosphere, climatic shifts that tipped the globe into prolonged ice ages and a gigantic asteroid strike that kicked up enormous clouds of dust.
The early part of Kolbert’s new book is an exploration of this exploration of the past, telling the stories of scientists who worked to reconstruct this grim timeline of species loss. But mostly it’s scene setting for the real subject of the book, the one telegraphed in the title: The Sixth Extinction.
The salient characteristics of the latest epoch are that we appear to be living through it now — and causing it…
That’s the start. In between the start and finish there’s lots of important science stuff.
It’s not that I have a solution I’m trying to work toward and just haven’t said what it is. I don’t have a solution. It’s possible that massive thinking and massive effort will yield, not a solution, but a much better future than the one we seem to be heading toward.
Sherwood Rowland, one of the scientists who discovered ozone depleting chemicals and who recently died, had a couple of great lines, including one I quoted in the book. “The work is going well, but it looks like it might be the end of the world…”
The politics of the discussion is simple enough:
“What’s the use of having developed a science well enough to make predictions if, in the end, all we’re willing to do is stand around and wait for them to come true?”
The combination of know-nothings, The Party of No, idjits and Cowardly Lions in Congress aren’t even doing that much. RTFA for lots more about the book, what can and can’t be done – you already know who needs to be thrown out of Congress and state legislatures to achieve anything more than political babble.
