But slashing greenhouse gas emissions as quickly as possible remains crucial to avoid even more devastating economic impacts after mid-century, researchers reported in the journal Nature. The study projects that -- absent climate impacts after 2020 -- global GDP would double by 2050 from $100 trillion in 2022.
