Climate change is “largely irreversible” for the next 1,000 years even if carbon dioxide (CO2) emissions could be abruptly halted, according to a new study led by the US National Oceanic and Atmospheric Administration (NOAA).

The study’s authors said there was “no going back” after the report showed that changes in surface temperature, rainfall and sea level are “largely irreversible for more than 1,000 years after CO2 emissions are completely stopped.”

The study found that CO2 levels are irreversibly impacting climate change, which will contribute to global sea level rise and rainfall changes in certain regions.

The authors emphasized that increases in CO2 that occur from 2000 to 2100 are set to “lock in” a sea level rise over the next 1,000 years.

Rising sea levels would cause “irreversible commitments to future changes in the geography of the Earth, since many coastal and island features would ultimately become submerged,” the study said.

Decreases in rainfall that last for centuries can be expected to have a range of impacts, said the authors. Regional impacts include — but are not limited to — decreased human water supplies, increased fire frequency, ecosystem change and expanded deserts.
