Climate change is one of the most formidable

developmental challenges faced by humanity today

Its consequences are global and intergenerational

The global climate is now changing faster than at any

point of time in human civilisation

Climate change will affect, in profoundly adverse way,

some of the most fundamental determinants of health:

food, air and water, adequate shelter and freedom from

disease

Introduction

Page 4: protecting health from climate change

A recent report from the Lancet and University

College London Institute for Global Health

Commission labelled climate change as “…the biggest

global health threat of the 21st century”

Developing and poor countries would face the earliest

and most severe threats

The health risks posed by climate change are

significant, distributed throughout the globe, and

difficult to reverse (WHO)

Page 5: protecting health from climate change

Problem statement

Since the early 20th century, Earth's mean surface

temperature has increased by about 0.8 °C (1.4 °F),

with about two-thirds of the increase occurring since

1980

Developing Countries & Small Island Nations will

be the first & hardest hit by this phenomena

Each year, about 800,000 people die from causes

attributable to urban air pollution

Page 6: protecting health from climate change

Problem statement

About 2.2 million die from diarrhoea ( due to lack of

access to clean water supply and sanitation & from

poor hygiene)

3.5 million die from malnutrition

60, 000 die in natural disasters

Climate change and Global warming:

Climate change refers to any distinct change in

measures of climate lasting for a long period of time

In other words, “climate change” means major

changes in temperature, rainfall, snow, or wind

patterns lasting for decades or longer

Global warming is an average increase in

temperatures near the Earth’s surface and in the

lowest layer of the atmosphere

Page 9: protecting health from climate change

Physical evidence for & examples of climatic change:

Global surface temperatures have risen by 1.3 degrees

Fahrenheit (ºF) over the last 100 years

According to the National Oceanic and Atmospheric

Administration (NOAA), seven of the eight warmest

years on record have occurred since 2001

The rate of warming across the globe over the last 50

years (0.24ºF per decade) is almost double the rate of

warming over the last 100 years (0.13ºF per decade)

Change In Surface Temperature

Page 13: protecting health from climate change

The evidence of climate change extends well beyond increases in global surface temperatures. It also includes:

Changing precipitation patterns

Melting ice in the Arctic

Melting glaciers around the world

Increasing ocean temperatures

Rising sea level around the world

Acidification of the oceans due to elevated carbon dioxide in the

atmosphere

Responses by plants and animals, such as changing migration pattern

Page 14: protecting health from climate change

Melting of GlaciersAmong the most sensitive indicators of climate changeTheir size is determined by a mass balance between snow input & melt output

Page 15: protecting health from climate change

Decline in Arctic sea ice, both in extent and thickness, over the last several decades is further evidence for rapid climate change. Satellite observations show that Arctic sea ice is now declining at a rate of 11.5 percent per decade, relative to the 1979 to 2000 average.

Global sea level has risen at the average rate of 1.8mm/yr during 1961-2003, the rate has been faster during 1993-2003 (@3.1 mm/yr)

Sea level rise

Page 17: protecting health from climate change

Causes of climate change

Human causes includes burning fossil fuels, cutting

down forests, and developing land for farms, cities,

and roads

These activities all release greenhouse gases into the

atmosphere

Natural causes include changes in the Earth’s orbit,

the sun’s intensity, the circulation of the ocean and

the atmosphere, and volcanic activity

Page 18: protecting health from climate change

Greenhouse effect

Discovered by Joseph Fourier in 1824

The greenhouse effect is one of the Earth’s natural

processes

It helps to regulate the temperature of our planet

Without a natural greenhouse effect, the Earth’s

temperature would be 0ºF (-18ºC) instead of its

present 57ºF (14ºC)

Page 19: protecting health from climate change

“Greenhouse effect” Green House Effect

• Sunlight brings energy to climate systems, most of it is absorbed by the oceans & land.• Heat radiates outwards from warmed surface of earth.• Some of the infrared rays is absorbed by green house gases.• Some of infrared rays further warms the earth.• Some of the infra red rays entered space

Page 20: protecting health from climate change

05/01/2023 20

Increasing greenhouse gases trap more heat

Higher concentration of CO2 & other green house gases trap more infrared rays in stratosphere. The additional heat further warms atmosphere & earth’s surface.

Earth's annual carbon cycle

Human activities emit about 9 Gt of carbon each year. About 4 Gt of this human-contributed carbon remain in the atmosphere; 3 Gt are taken up by natural terrestrial processes, and another 2 Gt are removed by the ocean (Canadell et al. 2007).

Stratospheric ozone depletion

Stratospheric ozone destruction is an essentially

separate process from greenhouse gas (GHG)

accumulation in the lower atmosphere

There are several important and interesting

connections between the two

First, several of the anthropogenic greenhouse gases

(e.g. CFCs and N2O) are also ozone depleting gases

Page 31: protecting health from climate change

Stratospheric ozone depletion

Second, tropospheric warming apparently induces

stratospheric cooling that exacerbates ozone

destruction

Third, depletion of stratospheric ozone and global

warming due to the build up of greenhouse gases

interact to alter UVR related effects on health

Ozone depletion in the stratosphere increases the

formation of photochemical smog

Page 32: protecting health from climate change

Climate Change and Ecosystems

Biodiversity:

Oceans: change in the habitat and food supplies for

many kinds of marine life—from plankton to polar

bears, coral bleaching etc

Forests: Longer periods of hot weather could stress

trees, and make them more susceptible to wildfires,

insect damage, and disease

Page 33: protecting health from climate change

Climate Change and Ecosystems

Habitat: Climate change will alter, and in some cases

destroy, certain types of habitats

Invasive Species: Some of the species that thrive in

the new climatic condition might be invasive and

could gradually drive out or even kill native species

Serious Effects On Human Lives And Health

Page 36: protecting health from climate change

Major health consequences of climate change

1) Agricultural sector extremely sensitive, rising temperatures & more frequent droughts and floods compromise food security Malnutrition

2) Frequent extreme weather events (storms and floods) Deaths & Injuries Outbreaks of diseases, such as Cholera.

3) Both scarcities & excess of water Diarrhoeal disease

4) Heat-waves , especially in urban “heat islands” directly increase morbidity & mortality, mainly in elderly people with cardiovascular or respiratory disease. Also increase in ground-level ozone and hasten the onset of the pollen season Asthma attacks

5) Changing temperatures & patterns of rainfall alter the geographical distribution of insect vectors Vector borne diseases (Malaria and dengue are of greatest public health concern.)

Page 37: protecting health from climate change

Potential Climate Change Health Effects

• Heat-Related & Extreme events related Morbidity and Mortality

• Asthma, Respiratory Allergies, and Airway Diseases• Cardiovascular Disease and Stroke• Vectorborne and Zoonotic Diseases• Foodborne Diseases and Nutrition• Waterborne Diseases• Human development• Mental Health &Neurological Diseases and Disorders• Cancer

Page 38: protecting health from climate change

Heat & extreme weather -Related Morbidity and

Mortality• Heat waves, or extreme heat events, are characterized by

several days of temperatures greater than 90° F; warm, stagnant air masses; and consecutive nights with higher–than-usual minimum temperatures.

• Account for more deaths annually than hurricanes, tornadoes, floods, and earthquakes combined in the US

• Extreme weather events, sea-level rise, destruction of local economies, resource scarcity, and associated conflict due to climate change are predicted to displace millions of people worldwide. (200 million people worldwide by 2050)

Page 39: protecting health from climate change

Respiratory DiseasesAir quality affected through several pathways

– increases in regional ambient concentrations of ozone, PM2.5s fine particles, & dust.

– Increase production & allergenicity of aeroallergens (pollen mold & spores)

Aeroallergens act with other harmful air pollution worsen respiratory disease (Allergic rhinitis asthma and chronic obstructive pulmonary disease )

Ozone causes direct, reversible lung injury; increases premature mortality; worsens respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD); and may cause lasting lung damage.

PM2.5s are associated with respiratory and cardiovascular diseases, including asthma, COPD, and cardiac dysrhythmias

Global rise in asthma is an early health effect of climate change

Page 40: protecting health from climate change

Cardiovascular Disease and Stroke Dysrhythmias are primarily associated with extreme cold as

well as heat Stroke incidence increases with increasing temperature  Ozone are also associated with acute myocardial infarction Particulate matter associated with systemic inflammation,

deranged coagulation , thrombosis, blood vessel dysfunction atherosclerotic disease, compromised heart function, deep venous thromboses, & pulmonary embolism

Increased burden of PM2.5 is associated with increased hospital admissions and mortality from cardiovascular disease, as well as ischemic heart disease

Elderly and isolated individuals are at greatest risk

Page 41: protecting health from climate change

Vector-borne and Zoonotic Diseases

Distribution of vectors will change arising from: Increasing temperature Changing rainfall Cyclones, flooding Changes in animal host/reservoir populations Rising sea levels Malaria and dengue fever to re-emerge.Introduction & spread of new agents, such as West Nile virus.Some VBZD agents like Lyme disease & Hantavirus, which show evidence of seasonality & the range of these diseases could change with a changing climate

Page 42: protecting health from climate change

Food borne diseases

Increased occurrence of  Vibrio infection, especially seafood-borne disease associated with V. vulnificus & V. parahaemolyticus

Ocean acidification also lead to more virulent strains of existing pathogens & emergence of new pathogens

Drought encourage crop pests such as aphids, locusts, and whiteflies, as well as the spread of the mould Aspergillus flavus & thereby exacerbate malnutrition, poverty, and the need for human migration

Greater use of herbicides, fungicides, & insecticides, resulting in potential immediate hazards to farm workers

Page 43: protecting health from climate change

Waterborne disease

Increased risk from the:a) Concentration of nutrient and chemical contaminants b) Formation of toxic algal bloomc) Surface water contamination with human waste d) Changes in ocean and coastal ecosystemse) Changes in ph, salinity f) Contaminant runoff, leaching of arsenic, fluoride,

and nitrates from fertilizers & lead contamination g) Water security.

Severe outbreaks of cholera.

Page 44: protecting health from climate change

Human development• Environment can be a potent modifier of normal development

and behaviour

• Many of the chemicals that we use to control pests and improve crop yields can impact human development

• About 3% of all children born in the United States have a birth defect, some of which can be attributed to environmental causes (CDC)

• Environmental effects on development include subtle changes such as small reductions in IQ from exposure to lead, changes in onset of puberty from exposure to endocrine disrupting chemicals, birth defects such as cleft palate due to dioxin-like compounds, and fetal loss through exposure-related spontaneous abortion

Page 45: protecting health from climate change

Mental Health

– Anxiety and depression

– Post traumatic stress disorder, Insecurity

– Grief

– Stress, self harm and possible suicide

– Loss of social cohesion

– Solastalgia

– Specific impacts on children, women and elderly

Page 46: protecting health from climate change

Neurological diseases

Exposure to neurotoxins (eg. domoic acid ) in seafood, fresh & marine waters, pesticides & herbicide effects & heavy metals leads to onset and exacerbation

Amnesia Numbness Neurological deficits Learning disabilities Liver damage Skin and eye irritation Respiratory paralysis PD- and AD-like symptoms Epilepsy

Page 47: protecting health from climate change

Cancers Leaching of toxic chemicals and heavy metals from

storage sites & contamination of water with

chemicals.

Depletion of stratospheric ozone resulting in

increased UV radiation exposure increased risk of

skin cancers (BCC & SCC) & cataracts.

 Increased UV radiation with certain polycyclic

aromatic hydrocarbons (PAHs) phototoxicity &

DNA damage.

Vulnerability, Adaptation and Mitigation

Responses to climate change

Page 49: protecting health from climate change

• Vulnerability: In the literature of climate change, vulnerability is

defined as the combined measure of threats to a particular system.

• Vulnerability is the degree to which a system is susceptible to or

unable to cope with the adverse effects of climate change,

including climate variability and extremes

• Adaptation ability of a system to adjust to climate change in order

to reduce its vulnerability, and enhance the resilience to observed

and anticipated impacts of climate change

• Mitigation looks at limiting climate change by reducing the

emissions of GHGs (greenhouse gases)

Page 50: protecting health from climate change

Human responses to climate change

Page 51: protecting health from climate change

Vulnerability

Page 52: protecting health from climate change

• Vulnerability is a function of the character, magnitude and

rate of climate variation to which a system is exposed; its

sensitivity; and adaptive capacity (IPCC, 2001)• Mathematically,

Vulnerability = f (Exposure, Sensitivity, Adaptive Capacity)

• In other words, the greater the exposure or sensitivity, the

greater is the vulnerability.

• However, adaptive capacity is inversely related to

vulnerability. So, the greater the adaptive capacity, the

lesser is the vulnerability.

Page 53: protecting health from climate change

MITIGATION

"Mitigation is a public good; climate change is a case of ‘the tragedy of the commons’

Page 54: protecting health from climate change

Mitigation

• Efforts to reduce or prevent emission of greenhouse gases

• Using new technologies and renewable energies, making older

equipment more energy efficient, or changing management

practices or consumer behavior

• Protecting natural carbon sinks like forests and oceans, or

creating new sinks through green agriculture are also elements

of mitigation

• Multifaceted approach which includes energy, transport,

buildings, industry, agriculture, forestry, waste management etc

Page 55: protecting health from climate change

KYOTO PROTOCOL

Page 56: protecting health from climate change

• The Kyoto Protocol is a protocol to the United Nations Framework Convention on Climate Change (UNFCCC), aimed at fighting global warming

GOAL: • “Stabilization of greenhouse gas concentrations in

the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system”

• The Protocol was initially adopted on 11 December 1997 in Kyoto, Japan, and entered into force on 16 February 2005

• As of September 2011, 191 states have signed and ratified the protocol

Page 57: protecting health from climate change

Brown = Countries that have signed and ratified the treaty             (Annex I & II countries in dark brown)Blue = No intention to ratify at this stage.Dark blue = Canada, which withdrew from the Protocol in December 2011.Grey = no position taken or position unknown

Participation in Kyoto Protocol as of 2011

Page 58: protecting health from climate change

TARGETS:

Total: reduce emissions to 5.2% below 1990 levels during

“commitment period” 2008-2012

(most countries need -18% reduction in BAU by 2008)

37 industrialized nations and the EU subject to binding

emissions targets

Greenhouse gases: CO2, CH4, N2O, HFCs, PFCs, and SF6

Page 59: protecting health from climate change

PENALTY:

Non-compliant countries will have to reduce emissions

by 1.3 units for

every unit of emissions “overshoot” in subsequent

commitment period.

Ex: if your emissions target is 7Gtons per year by 2012,

and you end up at 10Gtons/yr, in the next commitment

period (2013-2020) you will have to reduce by 4Gtons/yr

(in addition to any new targets) to be compliant

Page 60: protecting health from climate change

Three primary mechanisms1. Emissions trading

- trade carbon units between Annex 1 countries (flow is from

countries with carbon credits to countries with carbon

overshoots)

- example: Europe’s Emissions Trading System (ETS),

National Allocation Plans

2. Joint Implementation

- Annex 1 countries can invest in a emissions-reduction project

in another Annex 1 country and receive emissions reduction

units (ERU)

Page 61: protecting health from climate change

3. Clean Development Mechanism- Annex 1 countries receive ERUs for emissions reductions in developing countries- must certify reductions (they would not have happened without action by Annex 1)

Annex 1 Country e.g. J apan

Non-Annex 1 Country e.g. Thailand

I nvestment

Revenues

CERs (negotiated)

Page 62: protecting health from climate change

PROS:- For countries that are ultra-efficient, Kyoto would be cost

prohibitive. Such countries can ‘buy their way out’ by buying carbon credits from other countries

- Developing countries have incentive to reduce emissions by selling carbon credits

Page 63: protecting health from climate change

Recent Advances in Kyoto Protocol

• May 2011: Russia, Japan and Canada told the G8 they would not join a second round of carbon cuts under the Kyoto Protocol at United Nations talks and the US reiterated it would remain outside the treaty. They argued that the Kyoto format did not require developing countries, including China, the world’s No. 1 carbon emitter, to make targeted emission cuts

• Aug 2011: The European Union, the major developing countries, and most African and Pacific island nations declared that they would like to see the Kyoto process extended as a prelude to a more ambitious, binding international agreement that would take effect by 2020

Page 64: protecting health from climate change

United Nations Climate Change Conference-Durban, 2011(1/2)

• A primary focus of the conference was to secure a global climate

agreement as the Kyoto Protocol's first commitment period

(2008–2012) was about to end

• Also expected to focus on finalising at least some of the Cancun

Agreements such as co-operation on clean technology, as well as

forest protection, adaptation to climate impacts, etc

• Canada's environment minister Peter Kent announced his

country's withdrawal from the Kyoto Protocol

Page 65: protecting health from climate change

• The terms of the future treaty are to be defined by 2015 and become effective in 2020

• The agreement, referred to as the "Durban platform" includes developing countries such as China and India, as well as the US which refused to sign the Kyoto Protocol

• Green fund : The conference led to progress regarding the creation of a Green Climate Fund for which a management framework was adopted. The fund is to distribute US$100bn per year to help poor countries adapt to climate impact

Page 66: protecting health from climate change

India and Kyoto Protocol

• India will not sign any legally binding global agreement for emission reduction as the country needs to eradicate poverty through economic growth

• India argues that since the CO2 in the atmosphere is from developed countries it is their responsibility to cut down the emissions. However India will make all efforts to cut down on green house gas emissions but that would be voluntary

• India being a developing country is still not stable enough to take up global warming as the emission cuts will slow down its development and cripple it economically

Enter REDD: Reducing Emissions from Deforestation and Forest DegradationFact: 18% anthropogenic emissions comes from forest destructionIdea: Developed countries will pay for developing countries

not to destroy rainforest

Page 68: protecting health from climate change

BUILDING RESILIENCE AGAINST CLIMATE EFFECTS (BRACE)

• BRACE framework is a five-step process that allows health officials to develop strategies and programs to help communities prepare for the health effects of climate change

• Part of this effort involves incorporating complex atmospheric data and both short and long range climate projections into public health planning and response activities

• Combining atmospheric data and projections with epidemiologic analysis allows health officials to more effectively anticipate, prepare for, and respond to a range of climate sensitive health impacts

Page 72: protecting health from climate change

• Renewable resources will help India in mitigating

climate change, through reduction in dependence on

power generation by coal and mineral oil based power

plants, which contribute heavily to greenhouse gas

emissions

• Renewable energy sector is expected to contribute nearly

six times its existing emission reduction capability in

future

Adaptation

Page 80: protecting health from climate change

• Adaptation: Coping with climatic change – taking

measures to reduce the negative effects, or exploit

the positive ones, by making appropriate

adjustments.

• It depends on coping range, resilience range, and

failure range

• Climate changes threaten to slow, halt or reverse the

progress that the global public health community is trying

to achieved.

• In the long run, however, the greatest health impacts may

not be from acute shocks such as natural disasters or

epidemics, but from the gradual build-up of pressure on the

natural, economic and social systems that sustain health.

• Ongoing climate change, coupled with globalisation, will

make it more difficult to contain infectious diseases

• A fair and effective response will require a sharing of

responsibilities between the populations that make the

greatest contribution to climate change and those that are

most vulnerable to its effects, in order to safeguard and

enhance global public health security.

• Critically important will be factors that directly shape the

health of populations such as education, health care,

public health prevention and infrastructure and economic

development
