Vad händer
Kontext
I sin nya bok “Into the Clear Blue Sky” skriver klimatforskaren Rob Jackson om möjligheten och ansvaret människan har att återställa jordens atmosfär till förindustriella nivåer.
we shouldn’t only be trying to stabilize the Earth’s temperature at some arbitrary value. Instead, we can restore the atmosphere itself in a lifetime—and this should be our moral duty. Restoring the atmosphere means reducing the amount of greenhouse gases in the air to pre-industrial levels—starting with super-potent methane—to heal the harm we have done. Emissions must be cut, first and foremost. But to safeguard a livable planet for future generations, we must repair the damage we have caused.
Rob Jackson
Metan lämnar atmosfären på ett decennium. Den korta livstiden innebär att om vi eliminerar alla människans metanutsläpp, från jordbruk, avfall och fossila bränslen, kan vi återställa atmosfärens metannivåer till förindustriella nivåer på tio år. Det skulle spara en halv grads uppvärmning under vår livstid.
“Optimism and hope are muscles we have to exercise. I try to exercise them myself. I try to help my students exercise them too. I don’t want to pretend that solving the climate problem is easy or that we’re even close to anything like restoring the atmosphere. We’re not. But I can’t help but hope.”
Rob Jackson
Varje människa kan se den globala uppvärmningen som en möjlighet att göra oss friskare och låta oss leva längre liv. Varje klimatlösning bidrar till människans och andra djurs hälsa.
Particulate pollution from cars and coal still kills 100,000 Americans a year through heart and lung disease in spite of the progress we’ve made in improving our air quality. Worldwide it’s 10 million people. That’s more people than are murdered, die in traffic accidents and drown, combined. Globally, one in five of all deaths is attributable to burning fossil fuels. That’s 10 million people dying senselessly every year when cleaner fuels are available. I would love to help people see the link between climate action today and longer, healthier lives.
