Climate change will have a number of serious impacts on California, including
public health risks, damage to property and infrastructure, life-threatening events,
and impaired natural resources. This report focuses on how a changing climate
CROSSCUTTING
ISSUES is affecting the health of Californians and key issues the Legislature faces in
responding to those impacts. This is one of a series of reports summarizing
how climate change will impact different sectors across California.
We find that climate change has a wide variety of direct and indirect health
HOUSING
effects on Californians. In particular, rising temperatures and extreme heat events
are projected to increase deaths and exacerbate conditions like cardiovascular
disease and kidney failure. Similarly, additional wildfire smoke driven by a changing
K-12 EDUCATION climate leads to higher levels of respiratory illness, preterm births, and deaths.
The adverse health effects are not uniformly distributed across regions and
populations, however. Some areas are more susceptible to climate-induced disasters
or other changes, or are less able to adapt to these changing conditions. Certain
TRANSPORTATION populations, particularly lower-income, older, or medically compromised individuals,
as well as outdoor workers, will disproportionately bear the adverse health burdens
of climate change. Finally, changing climate conditions likely will challenge the
state’s health care delivery system in multiple ways—including placing additional
WORKERS & strain on emergency response systems and increasing demand for climate-related
EMPLOYERS
services—although the magnitude of these challenges is not yet well known.
As the Legislature considers various climate adaptation strategies within the
health policy domain, it will first want to consider how state health policies and
programs fit into the broader set of actions taken by individuals, the private sector,
local governments, and other state agencies. For example, state health departments
can play a vital role in supporting research on the health effects of climate change;
improving data collection, sharing, monitoring, and analysis; and evaluating which
health-related climate adaptation activities are most effective and efficient. This
information can be used to assist and support other state agencies and local
governments. The Legislature also may want to consider ways to ensure health care
delivery systems are adequately prepared to respond to climate change, particularly
climate-induced disasters. Finally, the Legislature will want to think about how the state
can reduce adverse health impacts on the most vulnerable populations. For example,
state policies and funding could be targeted in ways that support populations lacking
the resources to adequately protect themselves from the increasing health risks.
