This climate-change connection is straightforward: Warmer temperatures dry out fuels. Moreover, average summer temperatures in California were the hottest on record in 2021, breaking the previous JunethroughAugust record set in 2017. Researchers . Warmer temperatures and less water runoff during dry years also impair conditions for fish, aquatic wildlife, and migratory birds that depend on the states rivers, streams, and wetlands. California is home to a multi-billion dollar agricultural industry that provides thousands of jobs and produces more than 400 agricultural commodities, built on fertile soil, a temperate climate, and a complex network of water storage and delivery systems that have created an agricultural oasis where grasslands -- or even desert -- would naturally reside. The marketplace has largely collapsed, an advocate for counties in the state said. A new studyinvolving a mannequin wearing wigs in a wind tunnelreveals how. Wildfires. Climate scientists predict the region will get even hotter and drier. An official website of the United States government. The degree to which climate change will impact particulate emissions in the future is subject to some uncertainty, but researchers have estimated that particulate matter in fireprone areas could roughly double by the end of the century. Asdiscussed above, certain populationssuch as lowincome households, medically sensitive populations, and workers in outdoor industriesgenerally are more vulnerable to the effects of climate change. Here is a selection of our coverage of the connection between climate change and Californias wildfires. In the western Sierra Nevadas, the air is filled with smoke and haze from wildfires. Since 1990, the average annual number of homes lost to wildfires has increased by 300%. As global temperatures rise, understanding fire is becoming ever more important. These scientifically-based measurements track trends in various aspects of climate change and are useful for communicating information about the climate change issues confronting the state. But in the last decade, it's averaged 15 days per year with temperatures over 85, and some years it's more than. All rights reserved. [25], Drought-surviving sugar pines around Lake Tahoe have been found among 129 million trees in California killed between 2012 and 2016 by drought and bark beetles. To avoid unintended consequences, the Legislature will want to use a climate lens in considering new policies and projects that may have nonclimate related objectives as their primary goals. While California's climate has always made the state prone to fires, the link between human-caused climate change and bigger fires is inextricable, said Park Williams, a bioclimatologist at . "The 2006 California Heat Wave: Impacts on Hospitalizations and Emergency Department Visits". Despite inherent complications in assessing the indefinite costs associated with some potential climate impacts, such considerations will be important for the Legislature to take into account as it determines its priorities. United States EPA. As discussed in greater detail below, these prolonged periods of heat will have negative impacts on human healthsuch as by raising the risks of heat stroke and dehydrationas well impair agricultural production and natural habitats. Climate change will have a number of serious impacts on California, including public health risks, damage to property and infrastructure, lifethreatening events, and impaired natural resources. USA TODAY 0:00 1:10 California faces a "parade of storms" over the next several weeks, on top of deluges that have killed at least 14 people, caused flooding, knocked out power and forced. Extreme heat, heavy downpours, and flooding will affect infrastructure, health, agriculture, forestry, transportation, air and water quality, and more. During that period California's 38 million residents experienced 13 consecutive months of drought. For example, some of the most significant climate impactssuch as heat and wildfire smokedisproportionately affect certain medically vulnerable groups, including: children and the elderly, populations that have underlying medical conditions (such as asthma and cardiovascular disease), and populations that spend a lot of time outdoors (such as homeless populations and outdoor workers). Should we get lobsters high before eating them? Without climate change, the drought was probably finished already in 2005. Heres how you can help. Preparing the landscape to make future fires more manageable involves clearing fire breaks and building with more fire-resistant materials in areas of high risk. Greater climate risk is also aligned with particular occupations. SACRAMENTO - From record temperatures to proliferating wildfires and rising seas, California is already feeling the significant and growing effects of climate change, according to a new report released today that tracks 36 indicators of climate change and its impacts on the state. Similarly, costs associated with modifying and maintaining existing homessuch as replacing roofs or siding to be more fire resistant, adding air conditioning and filtration for heat and smoke, or elevating to reduce flood riskwill fall largely on homeowners. This, in turn, can lead to more diseased, dying, and dead trees, which can exacerbate the severity of wildfires by providing more combustiblefuels. In recent years, smoke from wildfires has grown substantially and has been a major contributor to air pollution in the western United Statesmaking up roughly half of small particulate matter in some regions, compared to less than 20percent a decade ago. For example, lowincome households have less money to purchase and operate air conditioning units during extreme heat events, air filters to moderate wildfire smoke, or backup electricity generators to provide electricity during Public Safety Power Shutoff events. The climatic conditions that cause this warning became more frequent because of climate change. Sea levels along the California coast are projected to rise by about six inches by 2030 and as much as seven to ten feet by 2100 compared to 2000 levels, depending upon the degree of warming the planet experiences. According to the states Fourth Climate Change Assessment, by 2100, the frequency of extreme wildfires burning over 25,000acres could increase by nearly 50percent. California Climate Change Assessments. It used to record an average of five days per year with temperatures over 85 degrees. Steps the Legislature could take include a new look at what role state policies should play in influencing where and how new homes and infrastructure are built to try to minimize their exposure to climate impacts. The impacts of sealevel rise along Californias coast will be widespread, affecting public infrastructure, private property, vulnerable communities, natural resources, and drinking and agricultural water supplies. Significant Funding in 202122 Budget Package. "Exposure to wildfire smoke has been linked to health problems such as respiratory infections, cardiac arrests, low birth weight, mental health conditions, and exacerbated asthma and chronic obstructive pulmonary disease.17 Longterm exposure to wildfire smoke generated an estimated $76 billion to $136 billion per year in health costs across the continuous United States from 2008 to 2012, with some of the most significant impacts in northern California. "[37], Expected increases in extreme weather could lead to increased risk of illnesses and death. Some Californians Are More Vulnerable to Negative Climate Change Impacts. In addition to balancing how much funding to dedicate for climate adaptation against its many other statewide budgetary priorities, the Legislature also faces the challenge of prioritizing spending among various activities to prepare for and respond to climate impacts. Warmer average temperatures and drier environments also create conditions that lead to extreme, highseverity wildfires. Francesca Hopkins, an assistant professor of climate change and sustainability at University of California, Riverside, released a paper last year that looked at how climate change will affect . When you purchase a homeowners insurance policy, the insurance company takes on a certain amount of risk. Hotter temperatures lead to more smog, which can damage lungs, and increases childhood asthma, respiratory and heart disease and death. An increasing number of Americans are moving into the zones known as the wildland-urban interface, where nature and development collide. Related: The Incarcerated Women Who Fight Californias Wildfires By choice, for less than $2 an hour, the female inmate firefighters of California work their bodies to the breaking point. [5] Changing weather and precipitation patterns could require expensive adaptation measures, such as relocating crop cultivation, changing the composition or type of crops, and increasing inputs such as pesticides to adapt to changes in ecological composition, that lead to economic degradation and job loss. ) or https:// means youve safely connected to the .gov website. While Californias climate has always made the state prone to fires, the link between human-caused climate change and bigger fires is inextricable, said Park Williams, a bioclimatologist at Columbia Universitys Lamont-Doherty Earth Observatory. Since 1985, more than 50% of the wildfire area burned in the western United States can be attributed to anthropogenic climate change. As fires spread through California during a global pandemic, read some of our past coverage about whats causing them and what might help contain them. Midwest. 88% of the area was drought-stricken. How is climate change affecting the ocean? Lack of water has led to more and larger wildfires in the state. The Golden State faces an onslaught from Mother Nature. Below, we discuss each of Californias climate hazards in more detail. The Legislature could also explore opportunities to incentivize landlords to modify their rental properties to mitigate the effects of heat and smoke on their tenants. For example, statewide transportation systems will experience a range of impacts, such as sealevel rise undermining coastal railways and bridges, intense storms causing mudslides and flooding of highways, and heatwaves causing buckling and rutting of roads. [18], According to the NOAA Drought Task Force report of 2014, the drought is not part of a long-term change in precipitation and was a symptom of the natural variability, although the record-high temperature that accompanied the recent drought may have been amplified due to human-induced global warming. Hundreds of thousands of some of the countrys poorest, most neglected workers continue to pluck, weed, and pack produce for the nation as temperatures soar into the triple digits for days at a time and the air turns to a soup of dust and smoke. A 2018 state report estimated that under current GHG emissions levels, between 45percent to 56percent of the natural vegetation in California will be climatically stressed by 2100. While the companion reports in this series highlight issues specific to different sectors, certain major themes are applicable across all policy areas. Scientists suggest the combination of these factors could lead to a 50percent increase in runoff in future years, challenging the capacity of the states existing reservoirs, canals, levees, and other flood control systems, and increasing the risk of inland flooding. [33], Ocean heat waves since 2013 have delayed three Dungeness crab seasons, due to harmful algal blooms that contaminate crab meat. That is, historical housing policies may be directly responsible for some unequal exposure to current and growing climate risks. Here's what you should know. Traditionally, landuse decisionssuch as where to construct housing, locate public buildings such as schools, or build roadswere informed by historical trends, such as how often an area had flooded in the past. Work in Some Industries May Also Become Less Stable. "Warming is affecting forest fire," said Park Williams, lead author and a researcher from Columbia University. For example, work and economic activity will be disrupted by flooding of ports, docks, surrounding roadways, or adjacent railways through which goods are distributedaffecting deliveries of imports across the state, as well as exports such as Central Valley agricultural products that are shipped throughout the world. [38] There are various diseases that will impact Californians as a result to climate change. How Climate Change is Affecting the Water Cycle and Water Availability in California. Certain homesparticularly older homesmay also need to add features such as air conditioning, modern insulation, and air filtration to mitigate the effects of extreme heat and outdoor wildfire smoke. Schools and child care providers will need to plan for how they can maintain continuity of education and servicesparticularly for more vulnerable and impacted studentsas climate change disruptions become more frequent. These closures affected an average of about 950,000 students per year in 201718 through 201920. From the earliest times, civilizations managed water extremestoo much (flooding) or too little (drought). Another bill that won Senate approval would require more than 10,000 companies with . Climate models predict that California will experience less frequent but more intense storm patterns in the coming decades, including the states precipitation more frequently falling as rain rather than snow compared to historical trends. The connections are very strong, scientists who have studied the issue say. The State Will Incur Some Costs Someof the costs of preparing for climate change impacts will fall on the state. [4], A study conducted in 2009 showed that increases in frequency and intensity of extreme weather due to climate change will lead to a decreased productivity of agriculture, revenue losses, and the potential for lay offs. Below, we highlight some of the most significant crosscutting statelevel efforts and funding. The story of Turtle, one of the world's first submersibles. Significant differences in the projected number of heatrelated deaths also exist within a particular region or city. How should the state prioritize among potential climate adaptation efforts? Given Limited Funding, Legislature Will Want to Select Activities That Most Effectively Meet Its Goals. As shown in Figure4, these changing conditions will impact the coast by leading to periodic and permanent flooding, eroding sand away from coastal cliff walls and beaches, and forcing groundwater levels to rise. This report focuses on how a changing climate is affecting transportation infrastructure and key issues the Legislature faces in responding . Higher temperatures catalyze chemical interactions between nitrogen Using a Climate Lens Can Help Avoid Increasing Future Risks. For example, K12 schools and child care providers will increasingly be impacted by disasters such as wildfires and floods interrupting their ability to offer inperson educational services. What is the appropriate role of the state in preparing for climate impacts? One key question will be what role state programs and policies can and should play in adapting to climate change, including how they interact with local adaptation activities, and how they should be funded. Given the complexity of these issues, this report does not contain explicit recommendations or a specific path forward; rather, it is intended as a framing document to help the Legislature adopt a climate lens across its policy decisions. Some funding options the Legislature could consider include: State Appropriations Limit (SAL) Consideration. These impacts are widespread and affect humans, animals, the built environment, and natural resources across the globeincluding in California. Taking steps to prepare for, respond to, and recover from climate change impacts will be costly. Some key categories of statelevel activities the Legislature could consider include: State Programs Can Explicitly Focus on Supporting Vulnerable Populations. Major activities include developing and maintaining the Adaptation Clearinghouse, a searchable database of resources; regularly convening a Technical Advisory Council to improve interagency coordination and develop tools and guidance; and administering a new climate resilience planning and implementation grant program (initiated through the 202122 budget). From 2012 to 2016, the state experienced one of the worst droughts in its history. The recent decadeslong surge in catastrophic wildfires in California is almost entirely due to climate change, a new study published Monday reports. Wildfire smoke affects birds too. Researchers suggest that particulate matter in fireprone areas could roughly double by the end of the century, andthat a 50percent increase in wildfire smoke could increase deaths of older adults by an additional 9 to 20 per 100,000 people annually. Grants/Funding California Native American Tribal Relations: Funding Opportunities [13] The 2020 season became the largest in the state's recorded history in terms of area burned, with more than 4 million acres burned across the state in 9,917 wildfires. Some of these impacts already are evident. We summarize some of the key crosscutting questions the Legislature will face in the coming months and years in Figure8 and discuss them in more detail below. Effectively responding will necessitate that actions be taken across state government. Smog forms faster in warmer weather, creating a health hazard for all of us, especially infants, children and the elderly. [27][bettersourceneeded], Extended periods of higher temperatures are expected to increase navel orangeworm reproduction, resulting in increased insect damage to almond, walnut, and pistachio crops. [17] 42% of its severity is due to temperature rise as a result of climate change. Some impacted roads, railways, bridges, and ports will need to be modified or relocated to remain accessible. Prioritization factors could include the immediacy of an expected climate impact, degree of state ownership and responsibility, number of Californians affected, potential fiscal and economic implications, threat to public safety, or the abilityor inabilityof certain communities to adapt without state assistance.
