Is it possible to end global warming

The study said that by the year , the planet's temperatures will be about 5. And sea levels will be roughly 8 feet higher. The authors suggest that global temperatures could continue to increase after human-caused greenhouse gas emissions have been reduced as the continued melting of Arctic ice and carbon-containing permafrost increase water vapor, methane and carbon dioxide in the atmosphere. The melting of Arctic ice and permafrost also would reduce the area of ice reflecting heat and light from the sun.

According to the study, to prevent the authors' projected temperature and sea-level rises, all human-caused greenhouse gas emissions would have had to be reduced to zero between and To prevent global temperature and sea level rises after greenhouse gas emissions have ceased, and to limit the potentially catastrophic effects on Earth's ecosystems and human society, at least 33 gigatons of carbon dioxide would need to be removed from the atmosphere each year from onward through carbon capture and storage methods, according to the authors.

Temperatures would then plateau but remain well-elevated for many, many centuries. There is a time lag between what we do and when we feel it, but that lag is less than a decade.

While the effects of human activities on Earth's climate to date are irreversible on the timescale of humans alive today, every little bit of avoided future temperature increases results in less warming that would otherwise persist for essentially forever.
