Climate change is a phenomenon that has been forever with us through ice age, times of great heat, droughts etc. But for last about hundred and fifty years what we see change, instead of being nature driven, is being driven by a range of activities that humans do. We simply use energy in the form of fossil fuel. If fossil fuel is burnt, Carbon Di Oxide (C0 ) is released in the atmosphere and it stays there.There is already enough C0 gas in the atmosphere and this additional C0 affects the environment causing climate change. The result is visible in the form of the increased frequency of floods, droughts, cyclones that in general are changing the world that we know.
Climate Change -What we can do? We must remember that the beginning of the whole issue is the emphasis on how we use energy. The fact that we can read, work, lecture, move etc is all generally dependent on the electricity or petrol. In a sense without energy the quality of life that we have or aspire tc have is not possible. Rememeber-Energy requirement is central to our existence and therefore is the first important thing to keep in mind There is always a question- how much energy is enough, how much energ should we use?
There are various ways of measuring it. If we look at all the countries of the world, we may find that one easy indicator to assess this can be quality of human development UNDP's Human Development Index (HOI).As a matter of approximation,if we assume HOI at 0.9 Is a level at which the quality of life Is one that every citizen of this country would proud to have. In case If this Is agreed upon, the fact Is that there Is no country In the world that has reached the levelof HOIat 0.9 without the energy supply equivalent to three tones all per person per year.
