Health Impact on Climate Change

Health Impact on Climate Change

What is Climate Change?

o Climate change is the result of long-term significant changes in our weather patterns.

o In understanding global climate changes it is necessary to combine many disciplines, including oceanography, meteorology, geomorphology, geology and paleoclimatology. 

o Climate change can be natural or caused by  changes people have made to the land or atmosphere.

Causes of Climate Interruption

• Major cause of climate change.

• 97% of climate scientists agree that climate-warming trends over the past century are very likely due to human activities.

• Deforestation, Burning of Fossil Fuels, Air Pollution are the main results of global warming caused by humans which eventually changes the climate.

Health Impact on Climate Change

The most vulnerable people—

(i) The children, (ii) The elders, (iii) The poor, and (iv) Those with underlying health conditions

—are at increased risk for health effects from climate change.

Facts...

Facts…In the heat wave of

summer 2003 in Europe for

example, more than 70,000

excess deaths were recorded.

Urban air pollution causes

about 1.2 million

deaths every year.

Rising temperatures and variable precipitation are likely to decrease the production of staple foods in

many of the poorest regions – by up to 50% by 2020 in some African countries.This will increase the

prevalence of malnutrition, which currently cause 3.5 million deaths

every year.

Facts…

Studies suggest that

climate change could

expose an additional 2

billion people to dengue

transmission by the 2080

Malaria is strongly

influenced by climate. Transmitted

by Anopheles

mosquitoes, malaria kills

almost 1 million

people every year.

the modest warming that has occurred

since the 1970s was

already causing over

140 000 excess deaths

annually by the year 2004

What Can We Do?

Think & Share ideas !Try something on your own !Reduce, Reuse & Recycle!Live a Eco-Friendly Life !

Use local bus or bicycle for movement or you can even walk in short journeys!!

Some Eco-Friendly Examples!
