Needed: new authority to build public health system capacity for climate change health threats

Strong public health system capacity is essential to protection against climate change health threats. Taken as a whole, the United States (U.S.) public health system lacks the requisite capacity. Unlike some other countries, the U.S. federal government and most state and local governments give low priority to strengthening public health capacity even though states and localities have begun investing billions of dollars in strategies to protect physical infrastructure from climate change-related severe weather events. I recommend enactment of new legislative authority specifically to develop public health capacity more rapidly and completely. Doing so can give new impetus to construction of, ultimately, a national public health system able to protect all those who reside in the U.S. from climate change health threats and to serve as a model for building such system capacity globally.
