People are understandably upset. Because it's nearly a decade and a half in the future, protests now include towering holograms and desperate calls to limit global warming — which has long since blown past 1.5 degrees Celsius (2.7 degrees Fahrenheit) — to 2 degrees C. One thing is eerily familiar, though: In one scene, demonstrators chant "net-zero now!" — a catchphrase with origins at the end of the last decade.
To some, this is a surprising slogan to hear today, let alone in 2037. Although the concept of global net-zero is rooted in climate science, today's carbon neutrality pledges from individual governments and corporations have been criticized in some quarters as a "con," because they allow polluters to continue emitting greenhouse gases. The carbon offset projects that are supposed to neutralize all those residual emissions are often questionable, if not a sham.
