Global climate change
Earth's average temperature is 14 de. C.
Earth's average Earth's average temperature is rising. The average temperature
on the Earth's surface in the twentieth century was about 0.80 d.C.
It is evident from the records of various temperatures that the increase has
increased. The main reason for this is the fact that gases such as carbon
dioxide and methane are considered to be emitting heat in the atmosphere, which
increases the atmosphere's ability to store heat, thus increasing the
temperature. Although this increase in temperature does not seem very big, the
results are of concern.
Consequences of global
temperature rise
1
Heat wave- Hundreds of people were killed in heat waves in Chicago in 1995 and in Paris in 2003. Such heat waves,
especially during the summer period, result in increased accumulation of
atmospheric dust and vapor, resulting in increased storage capacity of the
atmosphere and increased temperature. Heat stroke causes people to die
2
Thermal
islands - heat waves have become more
difficult, especially in large cities where the roads are paved in comparison
to the forest areas and construction of cement concrete, industrial and
vehicular pollution is high. In such places, there is an arbitrary increase in
temperature.

Increase
in sea water level - The rise in
global sea level is due to the melting of ice and glaciers. This could endanger
the coastal region, destroying coastal towns, flooding several islands
underwater, and destroying the habitat of many fish, birds and animals. This
kind of result is felt. The sea level is predicted to rise by 1 meter by 2100,
with serious consequences in the coming years.

The melting of glaciers on the
high mountain ranges and the melting of ice in the polar regions.- Although
avalanche is a natural activity, excessive glaciers and glaciers melt away are
serious. In the last 25 years, Gangotri glacier has receded more than 850
meters. This rate is 22 meters per year. It is unnatural to melt glaciers so
fast. This means that ice formation is slower than the melting point. Similar
is the case with the glaciers in Mount Kilimanjaro, the Alps

Other Results - As the
temperature increases, some other results can be seen as follows
A Jellyfish Breeding - As ocean water temperature rises, acid levels
are increasing, so jellyfish breeding is seen in large areas even in areas
where jellyfish did not exist.
B Increase
in number of mosquitoes - Due to the
humid conditions and high temperatures required for the breeding of mosquitoes,
the average temperature rise has increased the temperature of many regions.
Diseases like dengue are spreading in new areas as well.
C Coral reefs - Coral extracts the algae in their
cells, giving them a color change when the temperature changes. If sea
temperatures rise for 10 C to 20 C, prolonged bleaching
may result in coral color or even death. And currently corals are largely dead
due to bleaching activity in the sea. As a result, more than 1/5 of the world's
coral reefs have been destroyed.
Climate change -
Continuous change in the global climate model is called `climate change'. These
include changes in seasonal wind flows, changes in seasons, changes in tree
flow periods, increase in rainfall and drought frequency. Consists of
Climate Change Matters and Consequences
1 Chronic frequency and increase in
severity - In the past few years, there has
been an increase in the number and duration of chronic diseases eg. Floods
caused by rainfall in Mumbai in 2005, as well as floods, landslides and floods
in Kedarnath in 2013. In many parts of the world, there has been an increase in
the frequency of floods in different parts of the world.
2 Increase in the intensity and frequency
of droughts and hurricanes-
temperature rise etc. S The area of drought has doubled in the earth since
1970. As the temperature of the ocean increases, the water molecules on the
seabed become more active and the water vapor levels are increasing. It
produces hurricanes and droughts.
3 Crop Growth
Period and Changes in Agricultural Income
- Increased carbon dioxide in the atmosphere is affecting climate, agriculture,
air and human health.
Carbon
dioxide in the atmosphere above 350 ppm is hazardous to
the environment. It is also affected by rainfall and rainfall is affected by
crop growth.
4 Precipitation and climate change - Forests help keep the earth's temperature
low. In the region of wide rainfall, the cooling of the plants reduces the
speed of baptism and preserves the air naturally. But due to the large amount
of deforestation or burning of these forests, the air becomes hot and dry. This creates stress on the environment. Due to large-scale
deforestation, the rainfall profile has changed dramatically.
