Report on Climate Change, Public Health, and Sustainable Development Goals

Climate change presents one of the most significant threats to global public health, directly undermining progress toward the United Nations Sustainable Development Goals (SDGs). This report analyzes the multifaceted health impacts of climate change, framing them within the context of specific SDGs and outlining necessary actions at both governmental and individual levels.

Climate Change Impacts on Health and Sustainable Development Goals

Empirical evidence demonstrates a clear correlation between climate change and adverse health outcomes. These impacts challenge the core objectives of several SDGs, most notably SDG 3 (Good Health and Well-being).

Extreme Heat and SDG 3

Rising global temperatures due to the atmospheric accumulation of greenhouse gases lead to more frequent and intense heat waves. This poses a direct threat to SDG 3 by increasing the incidence of heat-related illnesses and mortality.

• Heat exposure can be fatal, particularly for vulnerable populations such as the elderly, outdoor workers, and individuals with pre-existing health conditions.
• Global heat-related deaths have shown a significant increase, with projections indicating that many urban areas will face life-threatening heat conditions more regularly.

Extreme Weather Events and SDGs 3, 6, & 11

Climate change intensifies weather events, including hurricanes and flooding, which compromises multiple SDGs.

1. SDG 3 (Good Health and Well-being): Increased risk of drowning, injuries, mold exposure, and mental health issues such as post-traumatic stress disorder.
2. SDG 6 (Clean Water and Sanitation): Flooding leads to water contamination from pathogens and toxic chemicals, compromising safe drinking water.
3. SDG 11 (Sustainable Cities and Communities): Extreme weather damages infrastructure and displaces communities, threatening urban safety and resilience.

Conversely, climate change also exacerbates droughts, which impacts food supplies and increases respiratory illnesses from dust and wildfires, further affecting SDG 2 (Zero Hunger) and SDG 3.

Air Quality Degradation and SDGs 3 & 11

Worsening air quality from wildfires and pollution directly conflicts with global health and sustainability targets.

• Wildfire smoke, containing fine particulate matter (PM2.5) and hazardous compounds, increases risks of heart attacks, lung cancer, and other respiratory conditions, undermining SDG 3.
• Warmer temperatures facilitate the formation of ground-level ozone, a lung irritant.
• The burning of fossil fuels, the primary driver of climate change, releases pollutants that cause severe health problems, impacting the goal of creating safe and healthy cities under SDG 11.

Infectious Disease Proliferation and SDG 3

Changes in temperature and precipitation patterns are expanding the geographic range and transmission season for vector-borne and other infectious diseases, creating significant challenges for SDG 3.

• Warmer conditions increase mosquito biting rates and accelerate the development of pathogens they carry, leading to the spread of diseases like dengue fever and chikungunya into new regions.
• Water-related risks include increased incidence of cholera and contamination from sewage overflows after heavy rainfall.
• Drought conditions can increase the risk of fungal infections like coccidioidomycosis (valley fever).

Impacts on Nutrition and Mental Health (SDGs 2 & 3)

Climate change threatens food security and mental well-being.

• Disruptions to agriculture from drought and extreme weather can lead to lower crop yields, threatening progress on SDG 2 (Zero Hunger).
• Climate-related disasters are linked to increased rates of anxiety, depression, and post-traumatic stress, directly impacting targets within SDG 3.

Vulnerable Populations and SDG 10 (Reduced Inequalities)

The health burdens of climate change are not distributed equally, exacerbating existing disparities and hindering progress on SDG 10 (Reduced Inequalities). Vulnerable groups include:

• Young children and older adults
• Pregnant women
• Individuals with pre-existing medical conditions
• Lower-income communities with fewer resources for protection and recovery

Recommendations for Action to Achieve Climate and Health Goals

Achieving the SDGs requires a dual approach of mitigation and adaptation, involving coordinated action from governments, corporations, and individuals.

Policy and Governmental Actions (SDGs 7, 11, 13)

Governments must lead the transition toward a sustainable and resilient future.

1. Promote Clean Energy (SDG 7): Transition from fossil fuels to renewable energy sources like solar and wind, which are now more cost-effective. This is a critical component of SDG 13 (Climate Action).
2. Enhance Community Resilience (SDG 11): Implement early warning systems for extreme weather, establish public cooling centers, and design resilient drinking water and sanitation systems.
3. Protect Public Health: Enact workplace safety regulations to protect outdoor workers from heat exposure and maintain strong environmental protections to limit greenhouse gas emissions.

Individual Contributions

Individuals can adopt healthier, more sustainable lifestyles that contribute to climate action and public health.

• Reduce personal carbon footprints through sustainable transportation and diet.
• Adhere to public health guidance during extreme weather events.
• Protect against vector-borne diseases.

Analysis of Sustainable Development Goals in the Article

1. Which SDGs are addressed or connected to the issues highlighted in the article?

1. SDG 3: Good Health and Well-being
   • The article’s central theme is the threat of climate change to public health. It explicitly discusses numerous health impacts, including heat-related illnesses and deaths, respiratory issues from air pollution (wildfire smoke, ozone), the spread of infectious diseases (dengue, chikungunya, cholera), and mental health problems like anxiety and depression following disasters.
2. SDG 13: Climate Action
   • The article is fundamentally about climate change, its causes (greenhouse gas emissions from fossil fuels), and its effects. It calls for urgent action by governments to mitigate climate change by cutting emissions and adapting to its impacts, such as strengthening resilience to heat waves, hurricanes, and flooding.
3. SDG 7: Affordable and Clean Energy
   • The article identifies the burning of fossil fuels in vehicles and power plants as a primary cause of climate change and air pollution. It advocates for a transition to clean energy, stating that “solar and wind energy are less expensive than fossil fuel energy” and criticizes government subsidies for the fossil fuel industry.
4. SDG 11: Sustainable Cities and Communities
   • The article discusses climate risks specific to urban areas, noting that cities like Miami, Houston, and Phoenix will face more days with life-threatening heat. It also suggests urban solutions such as making public transit available to reduce vehicle emissions and opening cooling centers during heat waves.
5. SDG 2: Zero Hunger
   • The article connects climate change to food security by mentioning that its impacts include “disrupting food supplies” and causing “lower crop yields,” which can reduce access to nutritious food.
6. SDG 6: Clean Water and Sanitation
   • The article highlights the risk of water contamination due to extreme weather. It states that increased flooding leads to “water contamination from human pathogens and toxic chemicals” and that heavy rainfall causes “sewage-contaminated stormwater overflows into lakes and streams.”
7. SDG 15: Life on Land
   • The article discusses the impact of climate change on terrestrial ecosystems, explaining that “rising temperatures and aridity dry out forest and grasslands, making them more vulnerable to catching fire,” which leads to destructive wildfires.

2. What specific targets under those SDGs can be identified based on the article’s content?

1. Under SDG 3 (Good Health and Well-being):
   • Target 3.3: End the epidemics of AIDS, tuberculosis, malaria and neglected tropical diseases and combat hepatitis, water-borne diseases and other communicable diseases. This is relevant as the article discusses the spread of mosquito-borne diseases like dengue and chikungunya and water-borne illnesses from bacteria like Vibrio cholerae due to warming temperatures and flooding.
   • Target 3.9: Substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination. The article directly addresses this by detailing illnesses and deaths from air pollution caused by “wildfire smoke,” “ground-level ozone,” and the “burning of fossil fuels,” as well as health risks from “water contamination.”
   • Target 3.d: Strengthen the capacity of all countries, in particular developing countries, for early warning, risk reduction and management of national and global health risks. The article supports this by mentioning the need for communities to provide “early warning systems” for climate-related disasters.
2. Under SDG 13 (Climate Action):
   • Target 13.1: Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries. The article details the need to adapt to hazards like heat waves, hurricanes, and flooding by implementing measures such as opening “cooling centers” and improving workplace safety for outdoor workers.
   • Target 13.2: Integrate climate change measures into national policies, strategies and planning. The article underscores the importance of this target by criticizing the U.S. government’s move to “rescind that 2009 endangerment finding” and “reverse U.S. climate progress.”
3. Under SDG 7 (Affordable and Clean Energy):
   • Target 7.2: By 2030, increase substantially the share of renewable energy in the global energy mix. The article directly advocates for this by urging governments to “promote clean energy rather than fossil fuels” and highlighting that solar and wind are cost-effective alternatives.
4. Under SDG 11 (Sustainable Cities and Communities):
   • Target 11.5: By 2030, significantly reduce the number of deaths and the number of people affected and substantially decrease the direct economic losses relative to global gross domestic product caused by disasters, including water-related disasters, with a focus on protecting the poor and people in vulnerable situations. The article discusses deaths from the “Pacific Northwest heat dome in 2021” and “drownings” from flooding, emphasizing risks for vulnerable groups like the elderly and lower-income people.
   • Target 11.6: By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management. The article connects directly to this by discussing how climate change is “worsening air quality” through wildfire smoke and the formation of ground-level ozone.

3. Are there any indicators mentioned or implied in the article that can be used to measure progress towards the identified targets?

1. Mortality Rate Attributed to Disasters and Pollution:
   • The article provides specific data, stating that “Heat deaths have been rising globally, up 23% from the 1990s to the 2010s, when the average year saw more than half a million heat-related deaths.” It also mentions that the 2021 Pacific Northwest heat dome “killed hundreds of people.” These statistics serve as direct indicators for measuring the human cost of climate-related hazards (Targets 3.9, 11.5, 13.1).
2. Incidence of Vector-Borne and Water-Borne Diseases:
   • The article implies an indicator by tracking the geographic spread of infectious diseases. It notes that “dengue fever has turned up in Florida, Texas, Hawaii, Arizona and California” and that New York saw its “first locally acquired case of chikungunya virus.” Monitoring the incidence and location of such cases measures the health impact of climate change (Target 3.3).
3. Air Pollutant Concentrations:
   • The article explicitly mentions “microscopic particles (known as fine particulate matter, or PM2.5)” in wildfire smoke and the formation of “ground-level ozone” on warmer days. The atmospheric concentration of these pollutants is a key indicator for measuring air quality and its health risks (Targets 3.9, 11.6).
4. Greenhouse Gas Emissions Levels:
   • The article’s discussion of the government’s plan to lift “limits on greenhouse gas emissions from vehicles and power plants” implies that the total volume of national greenhouse gas emissions is a critical indicator for measuring progress on climate action (Target 13.2).
5. Share of Renewable Energy:
   • By advocating for a shift from fossil fuels to solar and wind, the article implies that the percentage of energy generated from renewable sources is a primary indicator of progress towards a sustainable energy system (Target 7.2). The mention of government “subsidizing the fossil fuel industries” suggests that the value of these subsidies is a negative indicator.
