This new generation of climate activists is picking up the torch, now lit by LED. They recognize they have a life-and-death stake in the climate system they will be inhabiting for longer than anyone in my generation. Some of them are the children and grandchildren of those who have gone before. People like Sophie Kivlehan, James Hansen’s granddaughter, who served as a youth plaintiff in the landmark Juliana vs U.S. government. Although dismissed last year, the case argued that the government was violating the youngest generation’s constitutional rights to life, liberty, and property, as well as failing to protect critical public trust resources.

When an Outside editor reached out to ask me to write this story, I was on a trip to Marble Canyon, Arizona, to train raft guide companies on what is happening with the river. I drove my diesel Sprinter van from Tucson to the site, which tallied 383 miles at 20 miles per gallon of gasoline. When I ran the numbers later, the lifecycle water footprint of my fuel was around 110 gallons. One drive to the work I do on the Colorado River used more than 20 times the water of everything I did with AI in 11 weeks. That comparison stopped me cold—and I study this for a living.

As the current owner of a diesel sprinter van… ouch.

despite having higher initial infrastructure costs to build because of overhead lines and electric substations, electric locomotives usually cost 20% less than diesel locomotives, according to the Environmental and Energy Study Institute. They offer superior performance and efficiency over diesel, featuring over 90% energy efficiency, higher acceleration and hauling power, lower operating costs (25%-35% less maintenance and costing up to 50% less to run) and zero tailpipe emissions. Electric locomotives don’t carry the weight of 3,000 to 5,500 gallons of diesel fuel. They surpass diesel locomotives while pulling urban and commuter trains, as well as pulling heavier freight trains because of their ability to be quieter with steady and high torque.

We should be running an electrification conversion across our entire rail infrastructure.

If US educational leaders were to consult their Swedish colleagues, the advice they’d likely get is not to remove digital technology whole cloth. “The goal is recalibration rather than reversal,” wrote Fälth. This was echoed in a statement sent to Undark by the Swedish Ministry of Education and Research: The “Swedish government believes that digitalization is fundamentally important and beneficial, but the use of digital tools in schools must be carried out carefully and thoughtfully.”
