Delay and Pay: Tipping Point Costs Quadruple After Waiting
Reversing climate change grows more costly the longer you wait, with costs quickly quadrupling immediately after tipping points are crossed

RICHLAND, Wash. Tip the first tile in a line of dominoes and youll set off a chain reaction, one tile falling after another. Cross a tipping point in the climate system and, similarly, you might spark a cascading set of consequences like hastened warming,
rising sea levels and increasingly
extreme weather.
It turns out theres more to weigh than catastrophic environmental change as tipping points draw near, though. Another point to consider, a new study led by researchers at the Department of Energy's
Pacific Northwest National Laboratory reveals, is the cost of undoing the damage.
The cost of reversing the effects of climate changerestoring melted polar sea ice, for examplequickly climbs nearly fourfold soon after a tipping point is crossed, according to
new work published today in the journal npj Climate and Atmospheric Science. Much work has been done to explore the environmental costs tied to climate change. But this new study marks the first time researchers have quantified the costs of controlling tipping points before and after they unfold.
Common examples of Earths tipping points include melting ice sheets and dwindling tropical coral reefs. As ice melts and reefs die off, drastic environmental effects like flooded coastal cities and lost biodiversity soon followa shared trait among what the Intergovernmental Panel on Climate Change defines as critical thresholds in a system that, when exceeded, can lead to a significant change in the state of the system.
Oh! So,
catastrophic environmental change isnt the only concern! It might cost us more money too!
Now youve got my attention!
