Ice
melting, big chunks of glaciers will break off and become like ice cubes in a
big glass of water. The icebergs create mass in the ocean. The icebergs dislodge
the water causing the ocean level to rise. Some of the shoreline in many places
like Bangladesh-where the land is at a low altitude- will go under water.
Rising
global temperatures are expected to raise sea level, and change rainfall and
other local climate conditions. Changing regional climate could alter forests,
crop yields, and water supplies too. It could also affect human health,
animals, and many types of ecosystem. Deserts may expand into existing
rangelands, and features of some of our national parks may be permanently vanished.
The
earth has had highs and lows, droughts and floods, but nothing has been like
the past 150 years. Global warming is
affecting immensely on plants, animals, humans and the earth. We need to learn
how to conserve our use of fossil fuels to decrease carbon dioxide production.
This will slow down the effects of global warming
There
are many possible factors that can cause the warming of the atmosphere, for
example:
Natural deviation – the climate becomes warmer by
internal dynamics of the earth-atmosphere system.
Solar motion
– either direct increase of solar energy output or indirect mechanisms due to
solar activity may cause the surface temperature to go up.
Greenhouse effect – increasing greenhouse gases such as CO2,
CH4, NO, CFC
If the
scenario run results show warmer surface condition than the control, then it is
probable to suspect that the increasing CO2 concentration in the
atmosphere may cause warming
When the
climate becomes, the ocean may also become warmer in consequences. A warmer ocean has lower solubility of CO2
and hence will release further CO2 into the atmosphere. As we have informed
before, rising air expands and cools, causing clouds to form. The formation of
clouds will building block out the sun and the solar heating of the ocean
surface will cease. The surface will start to cool down. Thus the cloud formation
due to surface heating and convection is a downbeat feedback to the climate
system.
