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...
![Page 14: Health Impact on Climate Change](https://reader034.vdocument.in/reader034/viewer/2022051016/5574561cd8b42a0c468b4e5b/html5/thumbnails/14.jpg)
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
