Even if we stopped emitting greenhouse gas today, the Earth would continue warming for centuries. Arctic ice and permafrost are already on an irreversible path of melting.
That’s the finding of new research published Thursday in the journal Scientific Reports. The model suggests that even if emissions were to drop to zero this year, global temperatures would ultimately rise to be 5.4 degrees Fahrenheit higher in 2500 than they were in 1850 (that’s 3 degrees Celsius).
