While we have trouble adapting to the Fed's feints and hints about where its inconsistent policy is going, we will have less trouble adapting to future heat waves. It turns out that Mother Nature is more predictable than Janet Yellen. The NY Times reports that "deadly heat waves" can now be predicted two months in advance (see source). You don't have to be too much of an adaptation optimist to predict that thanks to this "Paul Revere" type early notification that death rates caused by heat will sharply decline. We are increasingly able to take a punch.
Of course, the poor have the least ability to protect themselves from such punches. How do we protect this group? First, the price of air conditioners continues to decline. The EPA should create a price index for key adaptation goods and measure how their purchase price and operating cost have changed over time. This CPI for adaptation would inform environmental justice research.
In the case of Los Angeles, public cooling centers exist. We must make it easier for people who do not have access to cars or even UberX to access these centers. Here is the list of centers. These small private and public steps are how we adapt.
