Republicans have sought to frame the Keystone XL pipeline as a job-creating project being thwarted by “radical environmentalists.” Is it? A new Cornell University study claims that the pipeline could actually have a negative impact on the economies of the states it would pass through.

“In the national debate, job creation has been set alongside environmental concerns in a rigid either-or fashion,” says Sean Sweeney, one of the study’s authors, “But oil spills also kill jobs, they consume resources, they have an impact on health, and can also lead to a lower quality of life.”

The range of estimates of jobs vary widely. TransCanada claims the pipeline will create 20,000 jobs. A State Department report estimates that only 20 permanent operating jobs would be created in the six states along the pipeline route. By comparison, those same states are home to robust agricultural, ranching and tourist industries that are dependent on water and vulnerable to environmental contamination. Across the six states agriculture employs 571,000 workers and tourism 780,000; the total revenue from those sectors, respectively, is $76.3 billion and $67 billion.

Sludge not crude

Tar sands oil — known in energy circles as diluted bitumen — may be more damaging to environments and communities than regular crude. Said Sweeney, “Diluted bitumen is an irregular substance — it runs thick and thin, hot and cold. It’s basically a sludge, not like regular crude — it behaves differently.” Tar sands also seem more likely to spill than conventional crude: The spill rate for diluted bitumen in the northern Midwest between 2007-2010 was three times the national average for conventional oil. This may be because the heavy, corrosive material puts greater stress on pipelines.

The already existing Keystone I pipeline, which runs 2,100 miles from Alberta to Illinois, began operating in 2010; in the two years since, 35 spills have occurred. In the pipeline’s first year of operation alone, its spill rate was 100 times TransCanada’s projection. All told the amount of tar sands oil being transported through the United States has more than tripled in the past decade to 600,000 barrels in 2010. Keystone XL, if built, would add another 830,000 barrels per day.



John Stansbury, a professor of civil engineering at the University of Nebraska, analyzed spill data from the Keystone I pipeline to estimate that 91 spills would occur over the course of 50 years of Keystone XL’s operation — close to two spills each year.  In a worst-case scenario, he says, a spill could contaminate 4.9 billion gallons of groundwater in Nebraska’s Sand Hills with benzene, a known carcinogen.

The threat the pipeline poses to Nebraska’s Ogallala Aquifer, which provides 30 percent of the irrigation water in the U.S., has been much-discussed, but the pipeline would also cross another 1,747 bodies of water, including the Yellowstone and Missouri Rivers and the Carrizo-Wilcox aquifer, the third largest aquifer in Texas.

If Keystone were to leak — or worse, rupture — the consequences could be serious. In July 2010, a pipeline operated by the company Enbridge ruptured — the company has never explained why — spilling 1 million gallons of tar sands oil into Michigan’s Kalamazoo River. The oil drifted 40 miles upstream, causing 145 reported instances of illness and health problems for people living in the riverside community of Marshall, Mich. Marshall residents living within 200 feet of the river were eligible for a buyout program; about 130 people sold their houses to Enbridge, leaving some areas uninhabited.

The Kalamazoo cleanup has cost $725 million so far — twice as much as Enbridge estimated — and the river remains closed to fishing, hunting and other recreational activities over a year and a half after the spill occurred. Officials in the Calhoun County Health Department have said some bitumen will likely remain in the river “indefinitely.” Sweeney points out that the rural areas along pipeline routes are unprepared to cope with spills.  “They had to bring someone in from the Gulf to deal with Kalamazoo,” he explained.

While the Kalamazoo spill was the biggest-ever tar sands spill, pipeline spills occur with startling frequency. In 2011 alone, there were 600 reported pipeline incidents. TransCanada’s website argues that “if they do occur, pipeline leaks are small,” yet pipeline spills caused 17 deaths and 68 injuries, and over $335 million in property damage. In 2010, when the Kalamazoo spill occurred, the damages from pipeline spills topped $1 billion. While pipeline spills don’t get the attention of disasters like the Exxon-Valdez and BP, they point to a familiar pattern of underestimating risk and underpreparing for disaster.

TransCanada insists that it will comply with all federal regulations, and construct and operate Keystone XL “to the highest industry standards.” Danielle Droitsch, an attorney with the National Resources Defense Council, argues that we don’t know enough about diluted bitumen to be able to transport it safely. “We’re building these pipelines as if they were conventional oil pipelines,” she said. “We don’t have any special regulations in place to deal with the fact that these are tar sands pipelines and they are very different. Until we have a new regulatory system in place there are no safety measures proposed that would make this pipeline safer.”

And in the meantime? “There’s no question this pipeline will spill — it’s a question of when.”

    California drought

    Since May, California has faced a historic drought, resulting in the loss of 63 trillion gallons of water. 95.4 percent of the state is now experiencing "severe" drought conditions, which is only a marginal improvement from 97.5 percent last week.

    A recent study published in the journal Science found that the Earth has actually risen about 0.16 inches in the past 18 months because of the extreme loss of groundwater. The drought is particularly devastating for California's enormous agriculture industry and will cost the state $2.2 billion this year, cutting over 17,000 jobs in the process.

       

    Meteorologists blame the drought on a large zone (almost 4 miles high and 2,000 miles long) of high pressure in the atmosphere off the West Coast which blocks Pacific winter storms from reaching land. High pressure zones come and go, but this one has been stationary since December 2012.

    Great Plains tornadoes

    From June 16-18 this year, the Midwest was slammed by a series of four tornadoes, all ranking as category EF4--meaning the winds reached up to 200 miles per hour. An unlucky town called Pilger in Nebraska was hit especially hard, suffering through twin tornadoes, an extreme event that may only occur every few decades. The two that swept through the town killed two people, injured 16 and demolished as many as 50 homes.   

    "It was terribly wide," local resident Marianne Pesotta said to CNN affiliate KETV-TV. "I drove east [to escape]. I could see how bad it was. I had to get out of there."   

    But atmospheric scientist Jeff Weber cautions against connecting these events with climate change. "This is not a climate signal," he said in an interview with NBC News. "This is a meteorological signal."

    Michigan flooding

    On Aug. 11, Detroit's wettest day in 89 years -- with rainfall at 4.57 inches -- resulted in the flooding of at least five major freeways, leading to three deaths, more than 1,000 cars being abandoned on the road and thousands of ruined basements. Gov. Rick Snyder declared it a disaster. It took officials two full days to clear the roads. Weeks later, FEMA is finally set to begin assessing damage.   

    Heavy rainfall events are becoming more and more common, and some scientists have attributed the trend to climate change, since the atmosphere can hold more moisture at higher temperatures. Mashable's Andrew Freedman wrote on the increasing incidence of this type of weather: "This means that storms, from localized thunderstorms to massive hurricanes, have more energy to work with, and are able to wring out greater amounts of rain or snow in heavy bursts. In general, more precipitation is now coming in shorter, heavier bursts compared to a few decades ago, and this is putting strain on urban infrastructure such as sewer systems that are unable to handle such sudden influxes of water."

    Yosemite wildfires

    An extreme wildfire burning near Yosemite National Park forced authorities to evacuate 13,000 nearby residents, while the Madera County sheriff declared a local emergency. The summer has been marked by several wildfires due to California's extreme drought, which causes vegetation to become perfect kindling.   

    Surprisingly, however, firefighters have done an admirable job containing the blazes. According to the L.A. Times, firefighters with the state's Department of Forestry and Fire Protection have fought over 4,000 fires so far in 2014 -- an increase of over 500 fires from the same time in 2013.

    Hawaii hurricanes

    Hurricane Iselle was set to be the first hurricane to make landfall in Hawaii in 22 years. It was downgraded to a tropical storm and didn't end up being nearly as disastrous as it could have been, but it still managed to essentially shut down the entire state for a day, as businesses and residents hunkered down in preparation, with many boarding up their windows to guard against strong gusts. The storm resulted in downed trees, 21,000 people out of power and a number of damaged homes.

    Debbie Arita, a local from the Big Island described her experience: "We could hear the wind howling through the doors. The light poles in the parking lot were bobbing up and down with all the wind and rain."

    Florida red tide

    A major red tide bloom can reach more than 100 miles along the coast and around 30 miles offshore. Although you can't really see it in the above photo, the effects are devastating for wildlife. This summer, Florida was hit by an enormous, lingering red tide, also known as a harmful algae bloom (HAB), which occurs when algae grow out of control. HABs are toxic to fish, crabs, octopuses and other sea creatures, and this one resulted in the death of thousands of fish. When the HAB gets close enough to shore, it can also have an effect on air quality, making it harder for people to breathe.   

    The HAB is currently closest to land near Pinellas County in the Gulf of Mexico, where it is 5-10 miles offshore.
