In the past 20 years, fuel has been the fastest growing export in the world, both in terms of volume and value. Oil makes up a huge portion of these fuel exports and is also the primary energy source for transportation throughout the world. Currently, the only alternatives to oil for the transportation sector are electric and hydrogen cell powered cars. Both of these are comparatively very small industries and only act as energy alternatives to on-road vehicles, while the transportation sector also includes all the world’s ships, planes, and military vehicles, which are all heavily dependent upon petroleum. As of now, oil is here to stay on planet earth, whatever its consequences may be.

Oil production in the United States has changed a lot in recent years. Following the discovery of the Bakken Shale formation in North Dakota and Montana, the United States increased its domestic production dramatically. The Bakken formation combined with the Eagle Ford and Permian Basins located in Texas allowed the U.S. to produce 66 percent of its oil domestically in 2014. The discovery of the Bakken Shale was hailed by some as an incredible discovery that will allow the United States newfound energy independence. But an equal number of people have objected furiously to our exploitation of the shale patch, claiming that it only further solidifies the United States on a path toward fossil fuel dependence. Our domestic production has decreased somewhat in the last two years as oil prices have dropped abroad, but overall our production rates are higher than they have been in a very long time and there is a considerable push to continue strengthening the industry domestically.

Now that a greater quantity of oil is being produced on the U.S. mainland than before, the amount of oil being shipped via tanker to the United States has dropped dramatically, which means that globally the risk of ocean oil spills has decreased as well. However, transporting oil domestically poses its own environmental problems and even imported oil often needs to be shipped to different parts of the country by land transport. If oil spills on the mainland, it can destroy ecosystems and watersheds and render communities unstable. If oil catches fire, it can lead to gigantic explosions, a few of which have historically had terrible consequences for American towns. Read on to learn about the pros and cons of different methods of oil transportation and the policy fights involved.

Rail

Currently, the most common method of oil transport is by railway. Truck transport of oil now only accounts for 4 percent of all petroleum moved because of its high level of inefficiency and risk. While pipelines can often be more efficient modes of transport, their construction can lead to political battles. The advantage of rail transport is that the infrastructure is already in place and already spans across America–all it needs is to be re-utilized.

Many railroads owners are willing to sign contracts with crude oil companies that allow for their railways to be used for transporting oil. Often these contracts are short term and many railway owners reserve the ability to withdraw from the business relationship later down the road. The railway transport business has grown exponentially along with the upward spike in oil extraction. Only 9,500 carloads of oil were moved on freight lines in 2008; by 2013 435,560 carloads of oil were moved, equivalent to 300 million barrels of oil.

However, this increase in railway transport has led to an increase in the risk of oil-related disasters. When a train transporting oil (also known as a “bomb train”) runs into a problem, it generally causes the oil to ignite, which results in an explosion. These explosions can be gigantic in size and result in large scale destruction. While railway movement is considerably safer than trucks in terms of land transportation, a single incident can have disastrous effects. This is further compounded by some evidence suggesting that Bakken shale produces a more flammable crude oil because of its specific mineral content. Because of North Dakota’s location in the very center of America, these bomb trains have to span incredible distances to move oil to the coasts of the country, which increases the risk that something may go wrong. Between 2013 and 2015 more than 10 major explosions took place in America.

The explosions can have devastating immediate effects, but oil leakage also poses its own risk. In 2013 alone more than 1.15 million gallons of oil were spilled. Oil leaks can take a considerable amount of time to clean up and the damage can happen very quickly. Oil is mostly made up of a combination of thousands of different hydrocarbons and is generally toxic to almost every living creature. Crude oil, in particular, is oil in its least processed form and poses a greater risk than refined petroleum to an area it enters and contaminates. Because of this, an oil spill can cause tremendous damage to an ecosystem. Furthermore, an oil spill in the ocean will eventually go away, partially through evaporation and partially through breaking down and falling to the ocean floor as an inert tar. However, if oil enters freshwater it can permanently render it undrinkable, which can be particularly serious in areas where humans live nearby and rely on freshwater for drinking water.

Pipeline Alternatives and the Keystone XL Expansion

Right now Canada is the largest U.S. supplier of foreign oil, which offers a certain level of ease of transport because the two countries are on the same landmass. Currently, 70 percent of petroleum products in Canada and the United States are shipped via pipeline. A certain amount of crude oil can be moved over the border on the Canadian Pacific Railway and Canadian National Railway, but there’s been a huge push to connect the two countries via new and larger pipelines. Pipelines would dramatically expedite the process of oil movement by making it both quicker and cheaper, and many argue that it would make the process dramatically safer for Canadian and American communities.

Much of the argument around pipeline transport has focused on the construction of the Keystone XL Pipeline expansion, a gigantic pipe system that would in theory run 1,661 miles between Alberta, Canada and Illinois. The oil giant TransCanada proposed Keystone XL in September 2008 and estimated that it would cost about $7 billion to create. Most of the labor force that would go into its  design would be from the United States, creating up to 20,000 new jobs. It would also generate about $585 million in taxes for the states it ran through and over $5.2 billion in property taxes over the course of its functional lifetime. Many saw the pipeline as an incredible chance to increase energy security and to generate new job opportunities. An equal number of people opposed the movement, saying it only put the United States at greater risk of leaks.

There are others who support the pipeline from an environmental/human health perspective. It’s important to remember that while one can object to oil as an energy source in theory, we still very much need it to live our normal lives. Oil transportation will happen one way or another, and pipelines are generally thought as being safer than trains and therefore the lesser of two evils. However, the distinction really depends on how you measure safety. If you use damage to human life and property as your metric, then trains are the far more dangerous method of transportation because they can generate large explosions. When something goes wrong on a train, the damage is immediate and severe. However, a leak from a pipeline can last indefinitely and may even go unnoticed, pouring a continuous stream of oil into the surrounding areas. Because of this, pipelines cause a much greater level of oil spillage overall than trains and may have a much more severe impact on the environment.

Keystone Pipeline Debate

There was a lot of opposition to the construction of the Keystone XL pipeline from environmentalists as well as worried community members who felt that their areas would be endangered by potential spills. A large portion of the public opposition to the pipeline has come from Native American communities that live in the states the pipe would run through. Several Native American groups in Nebraska especially have argued that the location of the pipeline directly endangers the Ogallala Aquifer, which sustains huge numbers of people and a thriving agricultural business. The sheer length of the pipeline is also alarming to many; while it ends in Illinois, the crude oil will then be processed in-state and shipped south via existing pipelines all the way to the Texas coast. This means that gigantic streams of crude oil would constantly be moving across the center band of the United States.

TransCanada argued that the pipeline would be built with state-of-the-art safety equipment, including over 16,000 smart sensors along its body, to allow for the quick relay of any problems and relevant information to repair teams. These sensors deliver information to satellites, which then dispatch emergency response crews that are located along the pipeline in each state. This level of security is particularly important because the Keystone XL would transport pre-processed crude oil to refineries. Crude oil is so thick that it has to be continuously heated in order to flow properly, which increases its volatility in the event of a spill.

Four years after it was initially proposed, President Obama rejected the Keystone XL expansion presidential permit in 2012. Not to be deterred, TransCanada began to explore alternative methods of building the pipeline and working closely with Nebraska, which led to the submission of another presidential permit less than half a year after the original rejection. The Obama Administration spent several years refusing to make a final decision on the expansion, saying that while it supports the pipeline’s ability to spur business and create jobs, it wouldn’t make a decision that will cause an increase in greenhouse gas emissions.

In November 2015, President Obama made the final decision to reject the Keystone XL pipeline, claiming that the benefit it would have for the economy in the long term wouldn’t outweigh the damage it would do to U.S. energy security and the country’s role as a progressive energy leader. TransCanada responded by asking for a delay on the review of the Nebraska route, which most likely would have pushed the final decision back for another indefinite period of time. This most likely would have placed the power of approving or rejecting Keystone XL in the hands of the winner of the 2016 Presidential race. However, the Obama Administration rejected this as well, ending the battle over the Keystone XL once and for all.

Conservatives were mostly furious and environmentalists were generally overjoyed. However, from a public health perspective, it isn’t completely clear what impact this decision will have. The risk of oil pollution will decrease but railway oil transportation and its dangers will remain prevalent instead. Furthermore, a large part of the argument from pipeline supporters is centered around energy security; increasing oil imports from Canada is viewed as a much safer business deal than increasing them from the Organization of Petroleum Exporting Countries, for instance. With the pipeline abandoned, it’s possible that the next energy argument will center around increasing oil extraction from U.S. reserves back to their 2014 levels and beyond, which would increase energy independence but also cause greater damage to the U.S. ecosystems and communities.

Conclusion

No method of oil transportation is completely safe, and different methods have their own advantages and disadvantages. Boats are generally the safest method for moving oil but have the greatest possible impact on the environment when they do actually spill. Oil movement on land is a completely different issue because it involves areas where humans live. While oil spills from trains result in higher levels of human death and property destruction, oil spills from pipelines are more common and often more severe, with longer lasting effects on the environment.

The extreme position is to fight against all forms of oil transportation under the argument that every resource dedicated towards oil industry infrastructure takes away from resources that could go to more progressive transportation technologies, such as electric cars and hydrogen fuel cells. Currently, the world is nowhere near ready to wean itself completely off oil, but competitor transportation technologies have steadily grown larger and larger in the past decades.

It’s important to remember that none of these alternatives are perfect and completely environmentally friendly–electric cars require large-scale mining operations to access the lithium iron for their batteries, for instance. However, overall a shift toward non-fossil fuel based transportation alternatives would still dramatically reduce global emissions. The world may not be technologically prepared to survive without oil, but as long as we depend on it, oil transportation and its risks and dangers will always be a factor in our lives and communities.

Out of context, the words “climate change” don’t sound very scary at all. Here’s the context that makes it scary.

The earth’s climate has been in flux since it burst into existence some 4.5 billion years ago. It’s been hot and cold and everywhere in between. Carbon dioxide in the atmosphere danced between 200-300 parts per million (ppm) during the earth’s long lifespan. But starting in the 1900s, carbon dioxide  pushed past the 300 ppm marker and kept climbing. Today, carbon dioxide levels “weigh in” at about 400 ppm. So what? Well, carbon dioxide and other greenhouse gases trap heat and send average temperatures climbing. Even worse, experts believe human activities like burning fossil fuels and deforestation increased carbon dioxide and caused climate change.

We’ve only been on the earth for a fraction of its lifetime. We’ve evolved based on certain conditions, and now those conditions are changing. In other words, we’re not well adapted for the world we’re creating. The changing climate is a crucible of possible human health complications.

Here’s what the future of health looks like if we don’t combat and adapt to climate change.

 Climate Change: What’s Happening?

Before I run away with how climate change will kill us all (just kidding!), let’s do a quick overview.

Greenhouse gases like carbon dioxide hang out in our atmosphere and absorb heat from the sun. Since these gases don’t occur naturally, the extra heat they absorb causes temperatures to increase above normal levels. As of 1900, carbon dioxide emissions from human activities have billowed up by 40 percent and global temperatures keep creeping upward too.

In our interconnected world, increased temperatures have implications beyond needing more A/C. Increased heat warms our oceans, melts polar and alpine ice, and drives up the sea level, which in turn facilitates stronger and more devastating storms.

Why is climate change bad for our health?

Ripples from climate change impact things directly related to your health, like the water and food supply. The World Health Organization predicts that climate change will cause 250,000 additional deaths a year between 2030 and 2050 because of heat stress, malnutrition, malaria, and diarrhoeal disease. Areas with fewer resources to adapt will suffer the most.

Here are some startling health scenarios of the future, and how climate change might cause them.

Diseases Will Become More Virulent

Climate change will make it easier for existing diseases to infect more people by altering their geographic range and lengthening the infection season. For example, ticks carrying Lyme Disease will cover more ground as more regions warm to temperatures where they can survive. Mosquitoes, which carry many diseases like Malaria and Dengue, will also flourish in warmer temperatures. High temperatures increase their reproduction rate, grow their breeding season, and enable them to bite more people. In general, all bacteria multiply faster in warmer temperatures, so many pathogens will find our warming climate suitable for proliferation.

Climate change might also encourage emerging and shifting diseases. Experts at the University of Nebraska-Lincoln say climate change makes it easier for diseases to switch to new hosts. Many assume that the co-evolution of pathogens and specific hosts will make it harder for pathogens to shift and infect a new host with different biological makeup. Alarming evidence has shown that pathogens can shift to new hosts rather quickly when necessary. The researchers offer Costa Rica as an example, where humans decimated the population of capuchin and spider monkeys. A parasite once exclusive to these monkeys was unphased and latched on to howler monkeys, a different genus of monkey. If pathogens need to make rapid shifts, humans might find themselves facing several for which they have no immunity. Climate change threatens to uproot habitats and living patterns, bringing humans, animals, and insects into closer contact with each other–and their unfamiliar pathogens.

More Will Die From Extreme Heat

Heat stroke and heat-associated dehydration are the most common causes of weather-related deaths. People with existing cardiovascular issues are especially vulnerable to extreme heat. Furthermore, heat complications have a cumulative effect; your vulnerability to heat stroke increases after one episode. Cities have been heating up at a higher rate than rural areas in recent years. This leaves some of the world’s most populated areas in danger.

Basic Hygiene Won’t Be Guaranteed

As rainfall becomes less predictable, it will compromise our safe water supply. With less safe water, it won’t be nearly as easy to do simple things that prevent disease, like washing hands. People take hand-washing for granted, but it reduces risk of diarrhoeal disease by 20 percent, which actually kills 760,000 children five and under annually.

Too much water, brought from the climate change risks of severe flooding, also wreaks havoc on sanitation. Floods contaminate freshwater, spread waterborne disease, and create ideal living conditions for mosquitoes–one of the most prolific disease carriers.

Breathing Won’t Be as Easy

Warmer temperatures bring more ground-level ozone, a miasma of pollutants like carbon dioxide and nitrous oxide. Ground-level ozone is also called smog, a term you’re probably more familiar with. It’s been known to damage lung tissue and aggravate respiratory systems. Increased smog will make breathing an excruciating task for people with existing lung diseases and Asthma. It might even encourage the development of Asthma in otherwise healthy people.

People with allergies should also be very afraid of climate change. The spring allergy season has already grown in the United States and it threatens to continue expansion. Ragweed allergies? Tests show that more carbon dioxide and higher temperatures increases the yield of ragweed pollen.

More People Will Go Hungry

Climbing temperatures, patchy rainfall, droughts, and floods will devastate staple crop yields in the world’s poorest regions. Malnutrition and undernutrition will burgeon as a result. By as early as 2020, crop yields in some African countries could be halved.

Increasingly severe weather already destroys crops. Pollinators disappear while pathogens and pests flourish to chomp through human crops. For example, soybean rust, a fungal infection caused by the pathogen P. pachyrhizi, spreads easily in warm, moist environments. Soybean rust has been a scourge in Asia and Africa for years and was introduced to the United States by a hurricane. Winds carry the spores for miles, leaving behind crop devastation. Similar diseases will most likely plague crops in new climates.

911 Might Not Be Working

Scientists believe climate change will lead to much stronger storms. The World Health Organization says that natural disasters reported globally have tripled since 1960, resulting in over 60,000 deaths.

Strong storms and natural disasters destroy medical facilities, cut the electricity that powers medical equipment, interferes with emergency communications tools like 911, and hinders transportation. Many injuries will happen in times when disaster strikes, even though our responsive capabilities will be restricted.

We Gotta Do Something

It’s pretty clear that we have to do something before things get out of hand. Do something…but what?

We’re flooded by climate change recommendations, but here are some key points from the 2014 National Climate Assessment. The assessment distills climate change responses into two main categories:

• Adaptation: Reducing negative impacts of climate change through infrastructure and preparedness planning. An adaptation example is the creation of the State, Local, and Tribal Leaders Task Force on Climate Preparedness and Resilience that aims to prepare communities for the challenges of changing weather.
• Mitigation: Attempting to reduce the climate change itself through updated policies and practices. A mitigation example is the Appliance and Equipment Standards Program, which pushes for energy efficiency.

While these two categories encompass different approaches, we need both to achieve the greatest effect. If you’re interested in reading about more climate change adaptation and mitigation initiatives, check out this fact sheet on President Obama’s Climate Change Action Plan. In terms of public health, however, we’ll stick to a few health-related initiatives, most of which fall under the adaptation category.

The Sustainable and Climate-Resilient Healthcare Facilities Initiative

As the name suggests, this plan aims to prepare healthcare facilities for climate change and related complications. The Department of Health and Human Services released an intensive guide with a framework designed to help healthcare facilities revamp their infrastructure and technology. The initiative includes an online planning toolkit that serves as an interactive guide to walk professionals through these steps of resilience:

1. Identify the problem.
2. Determine vulnerabilities.
3. Investigate options.
4. Evaluate risks and costs.
5. Take action.

So far, healthcare industry leaders like Kaiser Permanente have committed to use the guides to help in their resilience planning.

The BRACE (Building Resilience Against Climate Effects) Framework

The Centers for Disease Control and Prevention developed a framework of preparedness geared more toward public health professionals working locally. Their framework involves projecting the impacts of climate change and assessing effectiveness of interventions. The evidence of effectiveness will be especially useful for people planning future interventions. Click here to see a chart made by the CDC to explain the BRACE framework.

NYC Cool Roofs

The NYC Cool Roofs initiative presents a perfect real-world example of an initiative already underway. Reflective surfaces are added to New York City roofs, which mitigate further climate change by reducing cooling energy needed, consequentially lowering greenhouse gas emissions. They’re also adaptive as they’ll help cool the city, and hopefully reduce heat-related deaths.

Controversy in Congress

Many look at the Keystone XL pipeline decision to judge the climate change temperature in Congress. To the dismay of environmentalists, the Senate rejected two amendments related to the Keystone XL pipeline bill that admitted the human role in climate change and called for more government interventions. The President just vetoed the bill and many believe Congress will not override it.

Still, many climate change advocates are alarmed that the bill went as far it did, saying it would contribute to climate change because of the sheer amount of extra energy it would require and carbon pollution it would make. According to this NRDC Issue Brief, building the pipeline would create the same carbon dioxide emissions as Americans driving 60 billion more miles this year.

Conclusion

If you’re frustrated with the accuracy of forecasts now, be prepared. While climate change poses a new challenge without guiding evidence or precedent, the health complications from climate change have already begun. We see more cases of Lyme disease. Allergies grow in severity. We’re not sure what will work, we’re not sure what the future will bring, but we’re sure we need to brace ourselves for coming changes and meet current changes head on. We all need to work together to make sure that we stay healthy in coming years.
