How Climate Change Affects Health

The 2006 – 2010 drought turned 60%
of Syria’s fertile land into desert
By 2010, the drought had killed
80% of the country’s cattle
“I had 400 acres of wheat,
and now it’s all desert.”

farmer

A million people fled their homes
and farms due to drought
“…the Syrian minister of agriculture ... stated
publicly that economic and social fallout from
the drought was ‘beyond our capacity as a
country to deal with.’”

A 1° Celsius increase (1.8° Fahrenheit) in projected
mean temperature was found to decrease wheat
yields by nearly 21 percent.

Rising concentrations of CO2 are threatening global
nutrition by reducing levels of nutrients in food
crops like rice, wheat, and soybeans.

Climate’s Effects on E.M.’s Clinical Mission
1. Increase the incidence, prevalence and severity of many
conditions seen in the ED.
Heat Related Injuries
Exacerbated Chronic Conditions Vector Borne
Zoonotic Disease Respiratory
Water and Food Borne Urinary
Climate’s Effects on E.M.’s Clinical Mission
2. Patients who rely
disproportionately on the ED are
particularly vulnerable to
climate change.
-Marginalised Groups
-Extreme of Age
-With mental health concerns
3. Novel Diseases frequently present to the ED and Climate Change
introduces unfamiliar Vector-borne and Zoonotic Diseases into new areas.
-Rare
-Unknown
-Considered Eliminated
Climate’s Effects on E.M.’s Clinical Mission
Higher demand for ED Services
and increased surge capacities.

Climate’s Effects on E.D.’s Hospital & System Mgt.
1. Hospital ED has high intensity of
energy use.
2. EMS generates emissions through
patient transport.
3. Dependent on other specialties.
Vulnerable during system failure.
4. Reactive specialty.
5. High Cost.
The Target to stay within the 2 degree limit.
Assuming a world population of 9.5 billion people by
2050—this means that countries would need to
converge close to a global average of CO2-energy
emissions per capita of 1.6 tons in 2050, which is a
sharp decrease compared to today's global average
of 5.2 tons.

• Transitional adaption
• Transformational
