Discussion
In their paper, Dell and her coauthors estimated the impact of warming on GDP. They found no significant impact on the richer half of their data set. The case for this economic insulation from the effects of warming argues for an absolute income threshold for this insulation rather than a relative threshold. This means that worldwide economic growth will push more and more countries above the threshold, reducing the impact of warming. According to them, a constantly warming climate would slow the pace at which a country approaches this threshold and would cause GDP losses until it passes that threshold. Some countries would not pass the threshold by 2100.
