Earth is made up of different geographical regions. Global coastal regions are now going to vanish from each country. The main reason is the rising in the mean sea level. This decade is experiencing the highest rise in sea level. But, why mean sea level is rising? How we are involved in sinking our coastal region? How we can prevent it?

Future
By Dr. Arup Giri

2. Introduction
• Earth is made up of different geographical regions.
• Global coastal regions are now going to vanish from each
country. The main reason is the rising in the mean sea level.
• This decade is experiencing the highest rise in sea level.
• But, why mean sea level is rising?
• How we are involved in sinking our coastal region?
• How we can prevent it?

3. World Graphical Regions
The area of the Earth's five major latitudinal regions comprises of
geographical regions, separated by large latitude rings. The
differences between the two are climate-related. The details are as
follows:
The North Frigid Area, between 90°N of the North Pole and 66°33'N of
the Arctic Circle, occupies 4.12% of the Earth's atmosphere.
Between the Arctic Circle at 66°33'N and the Tropic of Cancer at
23°27'N, the North Temperate Region occupies 25.99% of the Earth's
surface area.
Between the Tropic of Cancer at 23°27'N and the Tropic of Capricorn at
23°27'S, the Torrid zone covers 39,78 per cent of the Earth's surface.
The Southern Temperate Zone, between the Capricorn Tropic at 23°27'S
and the Antarctic Circle at 66°33'S, occupies 25.99 per cent of the
Earth's surface.
From the Antarctic Circle at 66°33'S and the South Pole at 90°S, the
Southern Frigid Zone covers 4.12 per cent of the Earth's surface.

6. Reasons for Global Warming
• Global warming is caused mainly by an increased greenhouse effect,
or the tendency of some atmospheric gases to allow sunlight to enter
but not to depart. Though the Earth overall has natural periods of
warmer and colder temperatures, global warming exacerbated by
dense industry-produced gasses.
• Human activity isn't the only factor affecting the Climate on Earth.
Volcanic eruptions and solar radiation variations from the sunspots,
solar wind, and the location of the Earth relative to the sun also play
a part.
• For thousands of years now, greenhouse gas emissions to the
atmosphere are balanced out by natural-absorbed greenhouse gases.
As a result, concentrations and temperatures of greenhouse gas have
been reasonably stable, enabling human civilization to develop within
a predictable atmosphere.

7. How Global Warming Affect on the Arctic Region?
• The cryosphere consists of the ice of the Earth – especially the Arctic, the Antarctic,
and the glaciers of the world.
• Climate around the world is shifting. Earlier in the Arctic, and with more immediate
and severe effects, the impacts of climate change are being observed than in most of
the world. The Arctic is warming at a rate nearly twice the global average, and
declines in Arctic sea-ice and permafrost are becoming increasingly visible, as are
weather changes.
• The implications of a warming atmosphere are diverse, far-reaching, and
accelerating on the physical, chemical, biological, and human components of Arctic
ecosystems.
• The warming has triggered a cascade of physical changes, ranging from direct
effects such as the melting of sea-ice and sea-level rise to side effects such as
reduced albedo (surface reflectivity) and coastal erosion to tertiary effects such as
accelerated ocean warming due to feedback loops between various climate
influences.

8. How Global Warming Affects High Altitude Regions?
• According to a new study co-authored by Rutgers climate scientist Jim Miller,
global warming is taking place at an accelerated pace in many high-altitude regions
around the world, and among the effects could be water shortages.
• Globally, the team of researchers found that the rate of temperature change also
accelerates as the altitude rises. Temperatures above 4,000 meters (13,120 feet) have
warmed up 75 percent faster in the last 20 years than in altitudes below 2,000 meters
(6,560 feet).
• In tropical biomes, upper tree lines can reach above 4000 m and vascular plant
species above 5000 m, with extreme outposts above 6000 m in the Himalayas;
elevation limits of tree growth gradually fall to sea level at the margins of the Arctic.
• Given their global distribution, high-mountain ecosystems and their biodiversity
composition are considered to be sensitive indicators of the ecological impacts of
global climate change — especially in regions where direct human impacts from
traditional or modern land-use practices are low.

9. How to Prevent Glacier Melting?
• The greenhouse gases that trap heat are increasing, the global temperature is rising,
the Planet is warming up, the glaciers are melting, and the sea level is rising.
• This change in environment is impacting the wildlife and forests dramatically.
Indeed, the greenhouse effect is causing global warming.
• Some contributing factors include fossil-fuel burning, deforestation, livestock
production, and industrialization. As a result, it results in drought, constant rainfall,
hurricanes, extreme heatwaves, and other extreme weather.
• With these adverse effects of global warming going on all over the world, we need
to put in place ways to stop global warming and protect the Planet.

10. "Adults keep saying we owe it to the young people, to give
them hope, but I don't want your hope. I don't want you to be
hopeful. I want you to panic. I want you to feel the fear I feel
every day. I want you to act. I want you to act as you would in
a crisis. I want you to act as if the house is on fire, because it
is."
- Greta Thunberg
