Effects of Global warming

Global warming

Increasing global warming may not be a serious matter for most, but it has the vast potential to change the face of the earth completely, forever. The slogan ‘Save Earth’ or ‘Save Nature’ are very common these days but these doesn’t arise a sense of responsibility among most people as they simply walkout of the conversation by just saying “This is not my fight, I got a lot of other things to worry about”. Now I would like to remind you that earth was formed billions of years ago and since its formation, it has faced an unknown number of disasters and mass extinctions, but nothing really happened to it. Every time when something bad happened, some species that didn’t fit were wiped out, nature again played its role and new species were evolved. Now it may be a reason to think that this time it may be our species. So you should try to ‘Save Yourself’.

A small increase in few degree of temperature may not offend us in personal, but if this increase is as alarming as today's, it will have very serious effects on mass, which I would depict in the following paragraphs.

Effects on Flora & Fauna

A little bit of increase in temperature is good for flora and it increases productivity, but much of it is too bad for most of species as they die of sunburn and dryness. For fauna, it is mostly bad as it distorts their habitat and eating behavior. Due to high temperature, decomposition is enhanced leading to release of methane in the atmosphere, leading to further greenhouse effect. When the temperature is significantly high, many species which are vulnerable to climate change will go extinct, leading to further decomposition and further methane and other greenhouse gases.

Effects on Climate

Volcanic eruptions and Earthquakes

When the global temperature is high, the substances buried deep inside the earth starts changing state due to immense pressure and temperature leading to a requirement of an outlet. This causes an increase in the events of Volcanic Eruptions and Earthquakes all over the world.

Uneven whether

When the climate loses its balance, the temperature and pressure belts of all regions of the world show changes in them, leading to unexpected and completely different types of winds and cyclones. This leads to a formation of a completely different kind of weather cycle. There are many examples of floods in deserts and dry lands and draughts in regions of good annual rainfall or extremely high temperatures in summers and extremely low temperatures in winters in the recent years. The frequency of natural disasters like earthquake, tsunami, landslides, floods, massive cyclones has also increased. This unpredicted weather also leads to death of a large number of living organisms.

Floods

Since we have already talked about floods due to rains, we would move forward to another level of tsunamis. Everyone knows that glaciers around the world are melting at an alarming rate due to global warming, there is going to be a day when all the ice on the glaciers would end and all the water would be in the oceans. The first and the foremost thing that would happen after this would be that oceans will rise up to 1 meter and small countries in the oceans and islands would disappear from the globe. Sea coasts around the continents would shrink and annual rivers originating from glaciers would be dried. Apart from these, following the further effects of this sustainable flood-

1.         The day would become longer than 24 hours

When all the ice would melt, the whole mass of the water will be evenly distributed all over the world. Which would increase the mass distribution and hence Moment of Inertia of the Earth. Angular mechanics states that the angular momentum of any rotating body remains constant if there is no external torque on it. Since Earth revolves around its axis on its own in the absence of gravity, the angular momentum of the Earth must remain constant in every condition.

Now,

        L=I*ῳ

Where,

       ‘L’ is Angular Momentum

       ‘I’ is Moment of Inertia, and

      ‘ῳ’ is Angular Velocity

Since ‘L’ is constant,

      1/I ∞ ῳ

Hence, if moment of inertia increases, the angular velocity would reduce causing an increase in the day time.

This increase would have a very bad effect on almost all the species of the Earth. The migrating animals and bird species would confuse with seasons and hence most will die making wrong decisions. The body cycle of all the living organisms would change and lead to many new diseases.

2.      Failure of Ocean Conveyor Belt

With all the other glaciers, Green Land would also lose all its ice. Due to this there would be no disposal of ice in the sea and the downward flow of cold water wouldn’t start. Due to this, the Great Ocean Conveyor Belt would breakdown. Due to this the hot and cold water would not be circulated all over the world and the temperatures of the whole world would not be regulated. Above the surface of water, it would another ice age in the areas near poles and the temperatures near equatorial region would be unbearable for any species to survive. This large difference in temperature would also cause massive cyclones. The same thing would also happen inside underwater and most of the oceanic species of animals and corals will die. When the dead corals and aquatic animals would oxidize by using the dissolved oxygen and decompose. It would release organic substances in large quantity and methane would be mixed in the water in large quantity. It would also finish the oceans capacity to produce oxygen and absorb carbon die oxide from the atmosphere by killing all the living organisms inside the ocean including sea plants and all the corals. All these effects would together finish most of the life on earth.
