The radical environmentalist war on fossil fuels has opened a new front: a war on pipelines.

For years, activists claimed the world was rapidly depleting its oil and natural gas supplies. The fracking revolution (horizontal drilling and hydraulic fracturing) obliterated that argument, by sending US oil and gas production to new heights. Indeed, record gas supplies and plummeting gas prices combined with the Obama EPA war on coal to shutter many coal-fired power plants.

So the battle increasingly shifted to the far more emotional claim that continued reliance on fossil fuels (which provide over 80% of the US and global energy that powers modern civilization and living standards) will cause dangerous manmade global warming and climate change. This gave birth to the climate and renewable energy consortium and the “keep it in the ground” movement. No evidence to the contrary will budge them from their hysteria-laden talking points on looming climate cataclysms.

The prestigious journal Nature Geoscience recently published a careful study that found there has been far less planetary warming since 1998 than alarmist scientists and computer models had predicted. The models are based on the assumption that carbon dioxide drives climate change, and they “run too hot,” resulting in predictions that deviate from actual temperature measurements more and more every year.

But instead of admitting they were wrong, the usual strident suspects in the climate crisis industry doubled down and attacked the study and any news outlet that called attention to it. Even Britain’s BBC denounced the inconvenient study and displayed not a whit of apology over its climate chaos claims.

Climate campaigners jumped all over Hurricanes Harvey and Irma, insisting without an iota of evidence that they had been created or at least intensified by manmade greenhouse gases. They’re making the equally absurd claim that shutting down US and Canadian pipelines will somehow reduce atmospheric CO2 levels and prevent climate change and extreme weather – even though China already has 2,363 coal-fired power plants and is adding 1,171 more; India has 589 and is adding another 446; Indonesia and Vietnam are adding 140 to their fleet; and even Germany is burning more coal every year.

Pipelines get conventional, fracking and oil sands oil and gas to markets: natural gas to homes and power plants, oil to refineries, oil and gas to petrochemical plants – and crude oil, refined products and liquefied natural gas to export terminals that send the energy to Mexico, Europe and Asia. If they can’t prevent companies from producing oil and gas, hydrocarbon haters want to prevent them from shipping it.

“Obviously the best means of transportation of oil is none,” said an activist involved in campaigns against the Keystone XL Pipeline. But if there is going to be increased production, “I would rather it go by train.”

Some pipeline protesters somehow think rail or truck transport means the oil will be used domestically, whereas pipelined crude will more likely go to coastal refineries and be shipped overseas. Others claim pipelines are less safe than truck or railroad tanker cars. They cite a 2013 International Energy Agency report that said railroad transport is six times more likely to have an accident than pipelines are – but pipelines spill three times as much oil per-billion-barrel-miles of fuel transported.

However, the study is seriously outdated. It analyzed data from 2004 to 2012 – before the surge in US oil production … and before the monumental increase in rail transportation necessitated by protests and Obama Administration decisions that blocked construction of the Keystone and Dakota Access pipelines.

In 2014, the USA set a new record for railroad tanker spills: 141 – versus an average of 24 during the years covered by the IEA report. Rail accidents in Colorado, Virginia, West Virginia and other states resulted in significant oil spills, evacuations and even serious explosions, but fortunately no deaths. However, a 2013 disaster in Lac-Megantic, Quebec burned 47 people to death and left many others seriously injured. The danger of moving oil on rails and highways through populated areas is clearly high.

Better track maintenance, stronger tanker cars, improved train scheduling and other safety practices would reduce rail accidents and spills. However, US State Department studies concluded that the Keystone pipeline would likely result in fewer than 520 barrels of crude being spilled annually, compared to 32,000 barrels in three rail spills that it evaluated. The same holds true for other modern pipelines.

New pipelines are built with state-of-the-art pipe and other components, to the latest design, manufacturing and construction specifications. Warning systems, automatic shutoff valves, 24/7/365 monitoring and other safeguards further minimize the risk of spills. New lines often replace older pipes that carry greater risks of corrosion and rupturing as they age. New lines can often be routed to avoid population centers and sensitive water and wildlife areas. Because they are underground, once they are installed and grasses are planted, pipelines are invisible except for occasional pumping stations, valves and other small facilities.

Environmentalists tend to focus on potential volumes of oil spilled when a major pipeline rupture occurs, and on impacts to waterways and wildlife. While these are vitally important considerations, human safety should be of paramount concern.

Light crude oils from North Dakota’s Bakken Field and other shale plays contain more dissolved gases and thus are more flammable than heavier crudes. That makes explosions more likely. On highways and along rail lines through rural or urban communities, the results would be devastating. The sheer volume of oil to be shipped further underscores these dangers.

The 1,172-mile-long Dakota Access Pipe Line alone carries some 470,000 barrels of oil every day. Hauling that quantity overland would require 700 rail tanker cars per day (256,000 per year) or 2,000 semi-trailer tanker trucks per day on our highways (730,000 per year)! All would go through populated areas along parts of their route. Multiply that times the Keystone and other pipelines in planning or under construction, and the rail/truck “alternative” is mind-boggling in its scale and risks.

A new technology transforms heavy crude oil into pill-sized pellets, self-sealing balls of bitumen that can then be moved in coal rail cars or transport trucks with less risk of spills. That may eventually reduce the need for new pipelines; but it is just now in the testing stage.

Moreover, we cannot ship natural gas by tanker truck or rail car. Pipelines are essential for that.

Even more important, some activists are now going far beyond mere rhetoric and protests – and engaging in sabotage of pipeline construction equipmentand even pipeline safety valves. These intolerable acts should be met with police action, major fines and jail terms. Free speech and peaceful protests are absolutely acceptable. Eco-terrorism and threats to public safety cannot be tolerated.

These radical activists would never give up their reliance on – and addiction to – computers, smart phones, synthetic fiber shoes and clothing, affordable heating and air conditioning, cars, skis, kayaks, wind turbines and solar panels, and all the other blessings that petroleum brings us. They should not expect the rest of us to give them up, either. Especially for the phony reasons they cite.

For all these reasons, it is hard to understand the increasing opposition to pipeline building by states and communities: from Minnesota to New York and even Virginia and West Virginia.

It is even harder to understand or tolerate the actions of these tax-exempt anti-pipeline organizations – and the tax-exempt outfits that fund the radical groups: from the Rockefeller Brothers Fund to the Sea Change Foundation and its secretive Russian donors, and even to Warren Buffett’s NoVoFoundation.

If an increasingly divided, partisan, dysfunctional Congress cannot address these problems, perhaps the Trump Administration and some state governors and legislators can do so.
