Unlocking the Climate Crisis: Explore urgent insights on climate change. Navigate through the latest data, impactful visuals, and innovative strategies to drive awareness and inspire positive change.
Presentation from a Cary Institute of Ecosystems Studies public forum on climate change by Perry Sheffield, Professor of Pediatrics and Preventative Medicine, Mount Sinai
Public Health: Developed as a discipline in the mid 19th century in UK, Europe and US. Concerned more with national issues.
Data and evidence to support action, focus on populations, social justice and equity, emphasis on preventions vs cure.
What is global health?
Health problems, issues, and concerns that transcend national boundaries, which may be influenced by circumstances or experiences in other countries, and which are best addressed by cooperative actions and solutions (Institute Of Medicine, USA- 1997)
International Health: Developed during past decades, came to be more concerned with
the diseases (e.g. tropical diseases) and
conditions (war, natural disasters) of middle and low income countries.
Tended to denote a one way flow of ‘good ideas’.
Global Health: More recent in its origin and emphasises a greater scope of health problems and solutions
that transcend national boundaries
requiring greater inter-disciplinary approach

The elements which comprise the meteorological environment are:
Atmospheric pressure,
Air temperature,
Humidity,
Rainfall,
Direction and speed of wind and
Movement of clouds and character of weather.
A principal aim of epidemiology is to assess the cause of disease. However, since most epidemiological studies are by nature observational rather than experimental, a number of possible explanations for an observed association need to be considered before we can infer a cause-effect relationship exists.
Climate change is both a development issue and an environmental issue. Developing countries are more vulnerable to climate change than rich countries. CC may be limited to a specific region, or it may occur across the whole Earth.
It can be caused by recurring and cyclical climate patterns.
The causes of climate change are many. There is a need to understand these factors for reducing the effects.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

has contributed to climate change
in the same way
• combatting social injustice,
gender injustice, economic
injustice, intergenerational
injustice, and environmental
injustice

33. 1a. Climate Models And The
Use Of Climate Projections
• Projected climate data, such as future temperature and
precipitation, can be used to assess vulnerability and project
disease burden
• The climate models project possible future climate shifts under
the conditions of the specific scenarios. These models are run
multiple times using various scenarios of future conditions
• A climate outlook is a series of climate-related outcomes for a
future timeframe that gives probabilities that conditions, averaged
over a specified period, will be below normal, normal, or above
normal
• Health departments without staff capable of running climate
models can still use climate outlooks. However, small-scale
(downsized) climate outlooks that would be more useful for
district health departments may not be available.
34. 1b. Methodology for a climate
and health vulnerability
assessment
Identification of communities and places vulnerable to these changes in climate
can help health departments assess and prevent associated adverse health
impacts.
1. Frame and scopes of assessment,
2. A. Identify climate-related exposures, the geographic area and population
to study, the time frame to consider future changes in exposure, questions
to be addressed and steps to be used
B. Identify climate-sensitive health outcomes
2. Identify known risk factors for potential health outcome
3. Acquire spatial information on health outcomes and risk factors
4. Assess adaptive capacity
5. Assessment of vulnerability quantitative and qualitative(overlay analysis and
spatial regression) methods
35. 2. Projecting
climate-related
disease burden
1. Develop a causal pathway
2. Use ensemble projections from global
climate models
3. Establish the baseline disease burden.
3. Assess the exposure-outcome association
4. Project the health burden in a changed
climate
5. Evaluate the uncertainty.
36. Countries that have completed a
national climate change and health
vulnerability and adaptation
assessment
37. Major drivers for vulnerability (all states)
The multidimensionality of vulnerability is
evident in, for example, the most vulnerable
states Jharkhand, Mizoram, and Bihar.
They have multiple drivers of vulnerability (6-
7 for each state) encompassing biophysical,
socio-economic, livelihood, and institutional
and infrastructure- based indicators
One significant observation is that in
low vulnerable states, the overall
vulnerability is lower not because
they have a smaller number of
drivers, but because they have many
indicators in which they performed
extremely well
38. Major drivers of vulnerability (all districts)
The key drivers of vulnerability in Bihar
39. India’s
response to
climate
change
India’s approach is based on the following four key
considerations that underpin its long-term low-carbon
development strategy:
• India has contributed little to global warming. India’s
historical contribution to cumulative global GHG
emissions is therefore minuscule despite having a share
of ~17% of the world’s population.
• India is committed to pursuing low-carbon strategies for
development and is actively pursuing them, as per
national circumstances.
• The LT-LEDS aims to go beyond India’s climate targets or
the nationally determined contributions (NDC) of
achieving 50% of India’s cumulative electric power
installed capacity from non-fossil sources by 2030.
• India’s LT-LEDS rests on seven key transitions to low-
carbon development pathways.. These include electricity
systems, transport systems, urbanization, industrial
systems, CO2 removal, forestry, and economic and
financial aspects of low-carbon development.
40. Energy conservation act 2001
• This act requires large energy
consumers to adhere to energy
consumption norms
• The 2008 national climate action plan
builds on this legislation to achieve its
energy efficiency targets
• The energy consumption amendment
bill,2022 focuses on energy transition,
promoting renewable energy sources
and green hydrogen
Compensatory afforestation fund act
• The rationale behind this 2016 act is
around the concept of net present
value that encompasses services such
as flood moderation and carbon
sequestration
• Created the National Compensatory
Afforestation Management and
Planning authority(CAMPA)
National bulding code of india, 2016
• Part 11 of the code defines an
approach on sustainability that
focuses on energy efficient and other
environment compatible norms

41. National
Action Plan
on Climate
Change
• The National Action Plan on Climate Change (NAPCC) was launched
in 2008 by the Prime Minister's Council on Climate Change.
• It aims at creating awareness among the representatives of the
public, different agencies of government, scientists, industry, and the
communities on the threat posed by climate change and the steps to
counter it.
• There are 8 national missions forming the core of the NAPCC which
represent multi-pronged, long term and integrated strategies for
achieving key goals in climate change. These are-
• National Solar Mission
• National Mission for Enhanced Energy Efficiency
• National Mission on Sustainable Habitat
• National Water Mission
• National Mission for Sustaining the Himalayan Ecosystem
• National Mission for A Green India
• National Mission for Sustainable Agriculture
• National Mission on Strategic Knowledge for Climate Change
•
42. National programme on CC and human
health
• To create awareness
• To strengthen capacity of health
care system
• To strengthen health preparedness
and response
• To develop partnerships and
synergy with other missions
• To strengthen research capacity to
fill the knowledge gap
National Programme on Climate Change and Human
Health (NPCCHH) was launched by the
Ministry of Health and Family Welfare, Government
of India under National Health Mission (NHM) in
February 2019
Centre for Environmental Occupational Health and
Climate Change & Health Division at National Centre
for Diseases Control (NCDC) acts as the nodal agency
43. Challenges
• India has the potential to do things differently because it is in an early stage of development, and
it contributes very little to the changing climatic conditions. It can leapfrog to a low-carbon
economy by using high-end and emerging technologies.
• The plan report makes no commitment to cut the country's carbon emissions which should have
been an integral part of it.
• The focal point of NAPCC seems to be the solar power mission only and the government’s efforts to
maximize solar energy seemingly approve it. Equal emphasis on all missions with equal inputs
would have enabled the county to yield fast and visible results.
• Missions related to sustainable habitat, water, agriculture, and forestry are multi-sectoral,
overlapping, multi-departmental, advisory, and very slow-moving in nature. Several ongoing
activities are in principle aligned with the objectives of these missions which should either be
integrated with the missions or scrapped to save time and cost. Undertake climate-sensitivity-led
landscape restoration focused on rehabilitating, restoring, and reintegrating natural ecosystems as part of
the developmental process.
44. • UN and associated organizations have highlighted the importance of robust micro-level
vulnerability assessments, but such an assessment is absent in India
• Develop a high-resolution Climate Risk Atlas (CRA) to map critical vulnerabilities at the district
level
• Establish a centralised climate-risk commission to coordinate the environmental de-risking
mission
• Integrate climate risk profiling with infrastructure planning to increase adaptive capacity.
• Provide for climate risk-interlinked adaptation financing by creating innovative CVI-based
financing instruments that integrate climate risks for an effective risk transfer mechanism.
• A vulnerability assessment is a first step, considering only current climate risks. A future direction
of research and implementation is towards developing a climate risk map based on a hazard,
vulnerability, and exposure framework. There is a need for a climate- change risk index
development and a risk ranking of districts and states, based on a risk framework under climate
change, where:
Risk = f (Hazard, Exposure, Vulnerability)
Editor's Notes
This is a cross cutting topic which ranges from air pollution, water pollution, climate and global warming and reasons for that. These are all the hidden costs of human economic development, which we are trying to solve with the principles of one health.
This is the bottom of a coal mine in the 1800s where it shows a guy sitting at the bottom of the coal mine. The problem with the picture is not that he is not wearing a helmet but what he is trying to do. He trying to light something up which is either a pipe or a firecracker.
But lighting a flame in a coal mine is sort of a nice example of the reckless insouciance that was to characterize energy policy for the nest 200 years. Coal which we still use for energy production is a major culprit in contributing to the cimate change
This shows the global energy consumption by source from the 1800s to till now. I don’t wsanna go detail about the climate and the causes for it because I know we are all are fairly familiar with it.
Humans started using non-renewable energy sources such as coal, natural gas etc led to the release of greenhouse gases into the atmiosphere. CO2 water vapour, methane, nitrous oxide etc.. These compounds due to their heat retention capacity maintains the life on earth by the greenhouse effect. But over release of these gases and ecosystem destruction resulted in the warming up of the planet which caused the polar caps to melt and glacial retreat, hence rising the sea levels. The solubility of co2 decreases with increase in temperature where oceans usually absorb co2 and transfer them to deep ocean sequestering them.. Thus as oceans warm up the co2 will come bubbling out of the ocean like co2 comes out of a warm carbonated soft drink. Rising sea levels threat atleast one third of worlds coastal estuaries, wetlands and coral reefs. Changes in precipitation patters are expected to increase the chances of both drought and flood conditions in many areas. As drought icreases and spreads, the growth of trees and other plants decline, which further reduces the absorbtion of co2 from atmosphere. Increased precipitation is predicted in the polar and subpolar regions whereas it decreases in the middle lsttitude of both the hemispheres. But precipitation near the equator is predicted to increase. According to IPCC, projected climate change will increase the incidence of extreme weather such as heat waves, severe droughts, which could kil large number of people, reduce crop production and will help expand deserts.
Radiative forcing is a measure of the influence a given climatic factor has on the amount of downward directed radiant energy impinging upon the earths surfsce. Positive forcing is exerted by climatic factors that contribute to the warming of earths surface whereas negative forcing is exerted by factors that cool earths surface. As you can see the carbon dioxide has the maximum radiative forcing and least with aerosols.
.The pllutants with negative RF are ones that cause global dimming. Global dimming is defined as the decrease in amount of solar radiation reaching the surface of earth. Northern hemisphere ie where mos the people in the globe live has witnessed more significant reduction than southern hemisphere ie upto 4-8 %. Regions such as Europe and north America has observed partial recovery from dimming while parts of china and india are experiencing increase in global dimming. The pollutants that cause global dimming also leads to acid rain, smog and respiratory disease in humans.
Water in the northern hemisphere has also become colder which means less evsporation means less water droplets. This causes reduction in the amount of rain reaching certain parts of the globe, resulting in drought and famine situations. Also decrease in sunlight or solar radiation will negatively impact the photosynthesis in plants which means lea yield and nutrient quality.
The UN Framework Convention on Climate Change (UNFCCC)
International environmental treaty to combat "dangerous human interference with the climate system“
Multilateral environmental agreement
secretary-general of the United Nations
Parties 198
Conference of the Parties (COP)
- The COP is the highest decision-making body (represents all the parties – UNFCC)
- Very recent one (COP 27) which gained world attention was held from 6 November until 20 November 2022 in Sharm El Sheikh, Egypt.
The Intergovernmental Panel on Climate Change (IPCC)
- parent organizations are World Meteorological Organization (WMO) & United Nations Environment Program (UNEP).
Rio- adapted united nations framework convention on climate change, decided to orgsnise COP
Kyoto- aka international emmission reduction , production and sharing agreement
Copenhagen cc- officially defined the maximum acceptable increase in global temperature to be 2C above preindustrial era
Rio+20- linked climate change to sustainable development goals
Paris- all countries agreed to restrict global temperature bellow 2C and strive for 1.5C
Now I wanna talk about the ways in which CC threatens health. This is one of these diagrams that constitutes horrible powerpoint presentstion.. I really want to explain the complexity of it because the pathways through which CC affects arev complex.
Some of the changes are primary that is direct health effects such as trauma through cold or heat waves, death or disease risk….
Secondary are mitigated through ecosystem changes for eg : the conditions that give rise to infectious disease may change and that may change its transmission…..
Tertiary are mediated through changes in complex social processes ie migration, conflicts and so o n……
Heat causes heat stress, cardiovascular failure, decreased work capacity.
Sea level rise and severe weather cause injuries and fatalities, vector or water borne diseases
Air pollution causes asthma and cardiovascular disease
allergens cause respiratory and other problems
Resource scarcity and competition leading to maslnutrition conflicts forced migration etc
Last but not the least mental health is affected
EUROPE 2003 – 70K in three weeks
RUSSIA 2010 – 54K
Results show that, if there is no adaptation, heatwave-related excess mortality is expected to increase the most in tropical and subtropical countries/regions (close to the equator), while European countries and the United States will have smaller percent increases in heatwave-related excess mortality. The higher the population variant and the greenhouse gas emissions, the higher the increase of heatwave-related excess mortality in the future
For india its probably higher numbers. Over each of the past summers which were unusually hot, many people have died but we do not have good social statistics on these deaths.
A key challenge to the study of heat waves and health for developing country settings is a lack of health data. In such areas, standardized systems for health data collection for the purpose of conducting health research may not exist (Nori-Sarma et al., 2017). Additionally, local climate conditions in environments such as India with high baseline temperatures present challenges for extrapolating exposure-response functions from previous studies, which are primarily based in US and Europe with different populations and housing characteristics.
While previous literature in developed country settings showed that heat waves that occur earlier in the warm season are more impactful on health than later heat waves (Anderson and Bell, 2009, 2011; Hajat et al., 2006), we hypothesize that this may not be the case for our study region. In cooler climates, sensitive populations may succumb earlier to intense heat waves and other populations may have developed resilience to extreme heat.
Risk factors range from individual to community characteristics
Neighborhood characteristics – land use/land cover, crime rate, housing chararcteristics, and urban heat island effect
Heat waves in general have been found to be more threatening to cities for reasons such as larger population that is exposed, physical surface properties of urban land use, additional contribution from anthropogenic heat, and pollutants
There are physiological changes that help us withstand higher temperatures, but we can only acclimatize to a point.
Increased violence- rates of violent crimes increase. This may be true for suicides as well, suggesting that suicidees increase with increase in temperature
Kidney disease- working population in poor areas where people work dehydrated.

When global warming takes hold, there could be as many as 200 million people overtaken by sea-level rise and coastal flooding, by disruptions of monsoon systems and other rainfall regimes, and by droughts of unprecedented severity and duration.
Studies reveal that providing statistics can help earn people’s trust and motivate them to engage in healthier behavior.1Moreover, hearing a message from a trusted source, such as a health care professional, tends to make it more persuasive than it might otherwise be. Thus, clinicians have a powerful megaphone — and a profound responsibility — to effectively communicate health-related statistics
Four key tactics are providing a meaningful context, reducing the cognitive burden for the listener or reader, adding stories when appropriate, and furnishing feasible solutions
People can also be tripped up by overly complex information, hence the second key tactic for effective communication — reducing the cognitive burden
perceived efficacy is key to encouraging behavior change5; people need to know about possible solutions and effective actions that they believe they can take. Communications should include concrete calls to action. For example, health professionals can provide patients the information they need to protect their health during heat waves (e.g., how to identify cool locations during a power outage) or to help address climate change’s root causes (e.g., contact your government representative to demand a transition away from the burning of fossil fuels to safer, healthier renewable energy sources)
The emissions of the richest 1% of the global population account for more than twice the combined share of the poorest 50%. Compliance with the 1.5°C goal of the Paris Agreement would require the richest 1% to reduce their current emissions by at least a factor of 30, while per-person emissions of the poorest 50% could increase by a factor of about 3
Worldwide, in 2019, there were 396 disasters1 that killed 11,755 people, affected 95 million others, and cost nearly US$130 billion (28). Asia was the most affected continent with 40% of the events, 45% of the deaths, and 74% of all people affected.
However, state and local health departments often do not have the capacity to utilize climate data or climate projections
A Global Climate Model (GCM) combines a series of models of the Earth’s atmosphere, oceans, and land surface. GCMs divide the earth into many layers and thousands of three- dimensional gridded spaces. These models are skilled at replicating past and current climate. For example, GCMs accurately reproduce observed temporal warming trends, sea ice dynamics, and extreme weather events.
Each GCM is distinct and has a different sensitivity to greenhouse gas emissions. This range, taken as a whole, is important to researchers for providing a sense of the uncertainty surrounding possible future events given a particular scenario and period. To capture this range and make use of the complement of projections, ensembles of multiple global climate model simulations are often used.
Climate outlooks are based on results from running climate models. These outlooks may be useful to state and local health departments for anticipating the health impacts of climate change.
A benefit of using climate outlooks is that they do not require knowledge of how to construct or run climate models or interpret outputs from climate model runs. Health departments without staff capable of running climate models can still use climate outlooks. However, small-scale (downsized) climate outlooks that would be more useful for city and county health departments may not be available.
1…….. Identification of communities and places vulnerable to these changes in climate can help health departments assess and prevent associated adverse health impacts.
Climate-related exposures attributed to climate change would vary geographically and the rate of change would differ over time.
assessment could at least focus on near-term future projections (mid-century) or earlier
Health departments may choose a period that balances near-term public health planning, with long-term projections when climate change impacts become even large
B. The pathways through which climate-related exposures affect human health are complex (see Figure 4). For some pathways, changes in hazardous exposures have direct health impacts (e.g., cardiovascular complications during heat waves or road fatalities during extreme weather). There are other pathways where changes in local climate alter ecological conditions that affect vector ecology etc similarly there are social and health system conditions
2………Potential health risk factors includes social (e.g., education, social isolation), economic (e.g., income, social assistance), housing (e.g., housing type and age, prevalence of air conditioning), and neighborhood (e.g., land cover, parks, proximity to road) information.
3. ……..Sensus data of Demographic and socio-economic data for sub-populations can be used in GIS for mapping and analysis, by joining the census population data to the geographic data
May be measured by access to financial resources (e.g., federal aid programs), health infrastructure (e.g., hospitals or ambulatory services, cooling centers), or access to technology (air conditioning)
can be measured by the implementation of government programs, initiatives, or policies
4………adaptive capacity can be broadly defined as the ability of a system (e.g., government, infrastructure, civil society, institutions, social capital in community networks) to adjust, limit, and cope with the potential hazards, due to climate change.
Two quantitative approaches commonly used to assess vulnerability using GIS are
1) Overlay Analysis.
Overlay analysis is the underlying technique of methodologies that include risk factor analysis, environmental justice screening method(s), and social or medical vulnerability indices.
First, information on a suite of risk factors is collected from existing data sources related to the health outcome. Ideally, all of these risk factors would be measured in the same geographic units (e.g., county, census tract) so that they can be geographically aligned.
Each risk factor is then divided into categories based on the underlying distribution, with the more vulnerable categories being assigned a higher “score.” For each geographic unit (e.g., ZIP code, census tract, or county), the scores assigned to each risk factor are tallied to create a cumulative vulnerability score or index. These units are then mapped on the basis of the cumulative vulnerability score. If health outcome data are available, the overlay analysis can be validated.
) Spatial regression is another commonly used methodology for quantitatively characterizing vulnerability.
The primary distinction between spatial regression and an overlay analysis is at which step of the process one considers the health outcome. Spatial regression derives the most critical vulnerability characteristic based on the strength of statistical relationships between risk factors and the health outcome. Because of the direct connection between risk factors and health outcomes, spatial regression will likely exhibit stronger correspondence to health outcomes than overlays analysis.
However, spatial regression requires more statistical expertise and can take more time to complete. Specifically, computing time increases as the size of the analysis become more detailed or the number of risk factors increases. Therefore spatial regression may be most appropriate for health departments with an abundance of resources in terms of intermediate to advanced statistical capabilities, personnel expertise, and highly detailed health data availability.
In contrast, overlay analysis creates a vulnerability index from known risk factors of a health outcome and does not require health data, although the index can be validated with health outcome data in subsequent analysis.
Climate change disease burden projections are similar to other scenario-based modeling efforts used in public health. Examples include projections of the cholera outbreak trajectory in Haiti, the Ebola epidemic in West Africa, and long-term public health resource needs projections. While methodological specifics vary, all are decision-support tools that can help clarify how disease dynamics may shift in the future, highlight the consequences of particular management choices, and determine what resources are needed to achieve disease prevention and control goals.

Since the exposure-outcome associations may vary across different places, using locally available data to derive quantitative estimates may be beneficial. However, lack a of local data and inadequate scientific information may lead to reliance on qualitative assessment or the use of estimates available in the literature.
