Report: Climate change could flush your savings

Grist: “Businesses say risks to their bottom line from climate climate add up to tens of billions of dollars. That may seem like a lot, but their actual risks to business are at least 100 times higher, according to a study just published in Nature Climate Change. Trillions, instead of billions. The mismatch between those numbers could liquify the money you’ve been saving for retirement. Company climate plans “give little inkling that up to 30 percent of manageable assets globally may be at risk,” researchers wrote. Climate change could soon be “the defining issue for financial stability” according to Mark Carney, governor of the Bank of England and former head of the Financial Stability Board, the international body established to make recommendations to prevent financial collapse. To take that out of econo-speak: Failure to fully comprehend climate risks — droughts, floods, heat waves — could lead to an economic crisis that makes the Great Recession look like a joyride. The researchers had access to a treasure trove of data, environmental disclosures from 1,630 companies worth more than more than two-thirds of the world’s stock markets added together. It’s the biggest and most comprehensive study of this kind ever done. Some 83 percent of businesses said that they faced real risks from climate change, but only 21 percent had quantified those risks.

It’s fascinating to see how the one in five companies that have crunched the numbers anticipate climate change will affect their business. For example, Samsung estimated that if a cyclone shut down one of their semiconductor factories for a single day it would cost $110 million. And when monsoon floods stopped Hewlett-Packard’s hard drive manufacturing in Thailand, back in 2011, it cost the company $4 billion...the estimates of investor risk come from the Economist Intelligence Unit, academic research, and the World Economic Forum, not Conservation International. In this paper, the researchers simply tallied up all the adaptations companies are making…”
