True “Social Cost Of Carbon” Is More Than Double Earlier Estimates, Study Finds

Submitted by on November 30, 2017 – 5:33 pmNo Comment

by James Ayre (Clean Technica)  The true “social cost of carbon” is more than double earlier estimates — with even just an updated accounting of the agricultural sector on its own more than doubling earlier estimates in aggregate — according to a new analysis from the University of California—Davis and Purdue University.

Going on the new analysis, the true “social cost of carbon” is 72% to 129% greater than previously estimated following updated agricultural sector estimates. In addition, the new analysis shows that climate change has an overall net-negative effect on agriculture; and that every ton of CO2 emitted currently causes up to $8.50 in costs on agriculture.

Also noteworthy is the analysis shows that higher temperatures have net-negative effects on 4 major crops in essentially all of the locations where they are grown.

An email sent to CleanTechnica provides more: “This leads the overall social cost of carbon to increase from $8.60 per ton of CO2 to between $14.80 and $19.70, an increase of 72% to 129%. … Previous estimates were based on data from the 1980s and 1990s that suggested the short-term benefits of increased CO2 emissions on plant growth would benefit agriculture. The updated estimates show that climate change has an overall negative effect on agriculture.

The new study is detailed in a paper published in the journal Nature CommunicationsREAD MORE  Abstract (Nature Communications)
