What Mass Shootings and Global Warming Have in Common
by John Lawrence
Even if sales of AK-15s were banned today, there would still be enough AK-15s on the streets for mass shootings to continue for decades. Even if no more carbon dioxide goes into the atmosphere starting today, there is enough already there to provide weather disasters for decades. Meanwhile, gun sales and carbon dioxide generation are continuing apace. There will be no diminution of gun violence nor will there be any diminution of carbon dioxide entering the atmosphere. If there were zero gun sales tomorrow and zero carbon dioxide generation tomorrow, there might be a chance for recovery from both travesties, but, no, those travesties will continue along predictable lines. There will be even more mass shootings and assorted other gun violence while gas powered vehicles and power generating plants will continue to pump out carbon dioxide using the atmosphere as a waste dump. Plastic will continue to pollute the oceans. Chemical fertilizer and pest control chemicals will continue to pollute waterways. People pursuing the American Dream will continue consuming products to the point of commercial gluttony and beyond.
The production of steel and cement produces large amounts of carbon dioxide that goes directly into the atmosphere. It's a matter of sheer chemistry. Steelmaking is one of the most carbon emission intensive industries in the world. As of 2020, steelmaking is estimated to be responsible for 7 to 9 per cent of all direct fossil fuel greenhouse gas emissions. In order to mitigate global warming, the industry will need to find reductions in emissions. In 2020, McKinsey identified a number of technologies for decarbonization including hydrogen usage, carbon capture and reuse, and maximizing use of electric arc furnaces powered by clean energy. A Swedish company has developed a way of making carbon dioxide emission free steel. The Guardian reported:
The world’s first customer delivery of “green steel” produced without using coal is taking place in Sweden, according to its manufacturer.
The Swedish venture Hybrit said it was delivering the steel to truck-maker Volvo AB as a trial run before full commercial production in 2026. Volvo has said it will start production in 2021 of prototype vehicles and components from the green steel.
Steel production using coal accounts for around 8% of global greenhouse gas emissions. Hybrit started test operations at its pilot plant for green steel in Lulea, northern Sweden, a year ago. It aims to replace coking coal, traditionally needed for ore-based steel making, with renewable electricity and hydrogen. Hydrogen is a key part of the EU’s plan to reach net zero greenhouse gas emissions by 2050.
So the chemistry is being changed so that water H2O is produced as a by product instead of carbon dioxide, CO2.
CNBC reported:
Cars and electricity get a lot of attention in conversations about decarbonization, and they should. But building materials like cement and steel also need to be scrutinized.
The production of cement is responsible for about 8% of global carbon dioxide emissions and 5.5% of total global greenhouse gas emissions.
“We need to recognize that cement is a massive problem for climate and that nobody has figured out how to address it at scale without dramatically increasing costs or moving away from the regulated materials that the construction industry knows and loves,” Breakthrough partner Carmichael Roberts told CNBC.
So it is not enough to get gas guzzlers off the roads. Gas prices going up is a good thing. It will guarantee that more new car purchases will be hybrid or all electric vehicles. But the world is not changing over to non-polluting forms of energy quick enough. Major climate related disasters are already occurring and will continue to occur. Since we are still adding carbon dioxide to the atmosphere, these disasters will only get worse as time goes by. Meanwhile, all kinds of other ecological disasters are taking place including the insane and greedy pursuit of insatiable profits in the gun production industry and the buildup of military hardware. In 2019, a report released by Durham and Lancaster University found the US military to be “one of the largest climate polluters in history, consuming more liquid fuels and emitting more CO2e (carbon-dioxide equivalent) than most countries”. In addition to climate pollution the military is responsible for the development of assault rifles like the AR-15 which was first developed for combat operations. Very conveniently, it is now a profit center for US gun corporations, and in addition to killing combatants on the field of battle, it has brought war time slaughter into children's schools, people's super markets and night clubs. We've come full circle. And in addition the production of steel weapons results in increased carbon emissions.
