We all know, the earth is surrounded by a cover of gasses as atmosphere. This atmosphere allows most of the light to pass through, which reaches the surface of earth.

This light from sun is absorbed by the earth surface and converts into heat energy. This heat energy is re-emitted by the surface of the earth during night.

Due excessive presence of some gasses in the atmosphere, this escape of heat from earth surface is prevented, resulting in heating of earth called ‘global warming’.

The gasses which are responsible for causing global warming are called ‘greenhouse gasses’. Carbon dioxide is one of the most important greenhouse gases. This carbon dioxide mostly comes to atmosphere as air pollution from vehicles, coal-fired power plants and other industries burning fossil fuels. Human population increase and large scale deforestation are also responsible for carbon dioxide generation.

Thus, Global Warming adds energy to the Earth's biosphere.

The climate change which we are experiencing is due to global warming.

Heat is the fuel of weather systems. More heat, more extreme weather.

Energy drives the water cycle.

The more energy there is the faster the water cycle is driven and the more extreme the weather patterns become.

Each one degree rise in the temperature of the world's oceans is the equivalent to 1.4 BILLION one Megaton atom bombs; that is a lot of energy! This tremendous amount of devastating energy, generating because of our faulty creation “Global Warming” is responsible for the present climate change.

Thus, it shouldn't be surprising that the result is more extreme weather. More rain, more drought and more storms.

The harmful effects of presence of greenhouse gasses in atmosphere are global warming, climate change, ozone depletion, sea level rise, adverse effects on biodiversity etc.

Therefore, our prime responsibility is not to promote any industrialization which enhances carbon emission, rather than reduction.

Proper energy mix, which generates electricity without emission, is essential. Energy mix should include –

(a) substantial enhancement of Nuclear power in the industrialized countries;

(b) only clean coal technology / green coal to be used for power generation;

(c) wherever possible tap hydro-power;

(d) substantial effort needed to enhance research and implementation for provision of generation of clean energy from renewable sources such as solar and wind.

Rise in global warming - Ocean might have become 'saturated' with our emissions – An alarm bell:

Rise in global warming - Ocean might have become 'saturated' with our emissions – An alarm bell:

When the industrial revolution started, the level of CO2 in the atmosphere was around 280 parts per million by volume (ppmv) but that has risen to around 380ppmv due to our burning of fossil fuels. Because of tremendous rise in CO2 (about 35% rise) the global warming scenario has been deteriorated or faster. The melting of arctic ice, severe climate changes are some of the effects among many, of the global warming. This unexpected growth of CO2 level in the atmosphere, scientists suspect, is due to mainly two reasons –

(i) Inefficiency in the use of fossil fuels which increased the CO2 level by 17% and

(ii) Other 18% came from a decline in the natural ability of land and oceans to soak up CO2 from the atmosphere, i.e., decline in global carbon sinks. In addition, the growth of global population is responsible for significant growth of atmospheric CO2, as well.

A. The decline in global sink (there are two major carbon sinks in the biological cycle: the oceans and the land "biosphere", which includes plants and the soil) efficiency suggests that stabilization of atmospheric CO2 is even more difficult to achieve than previously thought. Study suggests, about half of emissions from human activity are absorbed by these natural "CO2 sinks" but it has been observed that, the efficiency of these sinks has fallen. Scientists believe global warming might get worse if the oceans soak up less of the greenhouse gas.

B. The weakening of the Earth's ability to cope with greenhouse gases is thought to be a result of changing wind patterns over seas and droughts on land. Nearly half of the decline in the efficiency of the ocean CO2 sink is, expected, due to the intensification of the winds in the Southern Ocean, study suggests. The declining effect is also being seen in the North Atlantic, as per the recent study.

C. In fact, the researchers are clueless about the exact reasons, whether this change in behavior of ocean is due to climate change or to natural variations. It is a tremendous surprise and troublesome factor because there were grounds for believing that in time the ocean might become 'saturated' with our emissions - unable to soak up any more. This phenomenon of ocean being saturated, leave us with all our emission to heat-up our globe – results rapidity in global warming.

D. We have to find out the ways to deal with this rapid pace in global warming. Implementation of carbon sink technology, iron fertilization of Southern oceans etc., have to be thought of. The major responsible factors such as, the issues like reduction of emission of greenhouse gasses in the atmosphere are to be tackled efficiently.

MOST IMPORTANT:

WE MUST REDUCE OUR CONSUMPTION OF NON-RENEWABLE RESOURCES.

WE MUST REDUCE THE GREENHOUSE GASES WE RELEASE.
