With every passing day, we may be losing the battle for our survival. The signs of climate change and the impending crisis are becoming more and more obvious every year, and will only get worse from here. From here on, it may not be enough to just slowdown the carbon emission. We need to reverse the process of climate change.
A Bomb About to Explode!
Once you reach dangerously close to a bomb
that is about to explode, simply standing there will not protect you from the
forthcoming catastrophe. The only way, if you wish to survive, is to run back
and away from disaster. The same is true for climate change today.
We have now accumulated enough green house
gases in our atmosphere to sustain the progress of further climate change. So
even if we stop at the current level of green house gases, the result will be
no different. The global warming will continue, and so will our story of self
destruction. The only way we can hope to avoid disaster is by reversing the
accumulation of green house gases. That is the only way we can hope to reverse
the process of global warming.
Need for
Urgent Remedies
To understand what needs to be done, there
is a need to look backwards, and understand as to how we have reached this
point. For thousands of years, we have used wood as fuel. In case of wood, the
carbon is derived from the atmosphere with the growth of the tree and goes back
to atmosphere after the burning of wood. Thus, the only carbon that goes to the
atmosphere is the carbon that is derived from the atmosphere. However the same
is not true of sequestered carbon that is stored below the surface as coal,
petroleum and gas. However, during these millennia, petroleum and gas were
unknown. Even though coal was not unknown, its mining and use were both limited
and its effect on environment was not significant.
Since the advent of industrial revolution
and the development of modern mining techniques, we have been using more and
more fossil fuel. In the process, we have released millions of tonnes of
sequestered carbon as carbon di oxide, carbon mono oxide and other green house
gases. In a few centuries, we have released carbon that was fixed by nature
over hundreds of thousands of years. This amount of carbon that is released in
atmosphere is far more than the amount of carbon that can be fixed by the
forests on this planet.
By using fossil fuel at current levels, we
will continue to add far more carbon to the atmosphere than can be fixed by the
forests on this planet. It means that at current levels, we will continue to
add more green-house gases, and thereby further aggravate the global warming in
coming decades. It also means that if we wish to salvage the situation, merely
preventing the rise of fuel consumption will not be enough. The only way we may
have a chance to survive is to reduce the fuel consumption, and aggressively
increase the forest cover on our planet. We need to do something that will add
more carbon to the Earth's crust than is being added to the atmosphere.
The
Enormity of the Challenge
This challenge is far great than we think
it is, because to be able to do what is required, we need to control our own
consumerism and energy-dependent life style, in addition to finding effective
sources of energy. As far as technological breakthrough is concerned, perhaps
our only real hope is solar energy, the only energy source that can fulfil all
our needs. The major obstacle in use of solar energy is cost, because cost of
solar energy is still nowhere near that of coal or gas. However, if one looks
beyond the cost of exploration and mining of fossil fuels, and adds the cost of
environmental damage that they are likely to cause, the fossil fuels will be
far costlier than the price at which they are marketed today. This uncovered
cost will have to be paid by our future generations, in terms of destruction of
life and environment.
We have now reached a time bomb that cannot be overlooked or treated with half hearted measures. We cannot survive merely by preventing further increase of fuel consumption. We need a drastic response from our society to reverse the green house gas accumulation. This is the one truth from which we cannot escape any more.
