Delayed action on climate to result in irreversible change and high costs
The physics of Earth’s natural systems show that a delay—of even a decade—in reducing CO2 emissions will lock in large-scale, irreversible changes. If carbon dioxide emissions do not begin to trend down this decade, it will be nearly impossible to stabilize the climate at any acceptable level.
“The Costs of Delay,” co-authored by Hal Harvey and Sonia Aggarwal, demonstrates that delaying action will escalate the risks and multiply the costs of dealing with climate change. Harvey and Aggarwal argue that the world has a window of about 10 years to bend carbon emissions curves downward and avert a climate catastrophe.
