The author talks about the importance of greening the earth.
Talks about the increase in population over the last 50-60 years ( I recall reading that the population of India of 1930 s used to be around 30 Crs) the population of the world in 1961 was some 3 Bn and that of India 0.44 Bio. World population now is 7 Bn and India's 1.24 Bn . There is need for energy for good quality life, but the increase in energy requirement, the likely increase further of the same with increased requirement by a significant population in China , India etc who at present do not enjoy access to energy plus the increase by the current users of energy would push the overall requirement to very high and unimaginable levels
He concedes that US has been one of the greatest energy guzzlers and also concedes that the other nations have a right to claim that they too have a right to enjoy good quality life , which at this point of time means, great energy consumption. The author talks how CO2 emission from around 280 ppm sometime at the beginning of Industrial revolution os closer to 400 ppm and showing clear signs of getting to 550 ppm
Author talks of how use of Fossil fuels like Crude oil,coal etc are increasing CO2 emissions dangeously.
The author talks of the impact of increased release of greehouse gases like CO 2 ,Nitrogenous oxides etc in to the atmosphere namley increaes in tempretaures across the globe, lower forest cover, increase in extremes , floods ( ice melting),droughts, tempests etc and .
Author may sound grandiose and boastful when he talks of the need for US to show leadership and how it is only US who can bail the world out of this but one has to concede that any author who undertakes to write on a subject like this is expected to think that they know something that others did not know or know but others have not cared to ariculate .. and are expected to sound preachy ,pedagogic. One needs to give allowance and get on to gather what the author says. He does quote a lot of experts and draws on their knowledge and experience. His use of statistics and analogies/metaphors sound a bit over the top but let us concede that he has done a good job and take the essence of the book.
The author somewhere along the line concedes that there may be a small chance that increase in greenhouse gases may in fact not cause climatic changes and take the world to a disaster as has been predicted but the probability is high that such an eventualitry is highly likely and argues as to why we should take a chance and also mentions that with or without thye worst consequences that are predicted, "greening" does bring enormous benefits.
One chapter almost fully,m he devotes to the petrol politices and how prices of petrol impacts the policies and behaviour of nations, He takes the example of Iran, Saudi Arabia and traces how increased prices led to increased influence by these nations , increased money in their hands led to increased funding of terrorism,increased funding if religious schools ( Madrasas) . With increased money , the mneed to be innovative and be connecte to the world to derive technical knoweldge etc gets less and with more time in the hands there is the temptation to spread religious fundamentalism. I think , increased money also gives you an aura on some ordained power.the author also traces how, US and European nations policy of reducing energy in the 80 s by use of fuel efficient vehicles, use of alternative fule etc brought the prices of oil down and almost brought the middle east nations to start behaving better
The author visited parts of Pakistan and gathers that most of the Madrasas there are funded by Saudi. Madrasa attract people since that is one way of escaping poverty , get food , get some education , may be the wrong type but all the same some education and respectaibilty etc. This chapter sounded very logical and sounded atleast to a reader like me who has a basic understanding but not a thorough knowledge of Middle east politics.
The author spoke to a number of experts on Environment and greening experts. Does make a good case for the need to green.He logically sidesteps the doubts cast on the possible ill effects of current emission of green house gases, CO 2 to a large extent by coming out with reasons to green even without the likelhood of those extremes.
Tropical forests just 7% have a disproporionately large variety of flora and fauna variety
Talks of Indoenisa's tropical forests and how deforestation there means higher emission.
Trees and plants absorb CO 2 (photosynthesis) , lets out Oxygen and also give out CO 2 . But absorption far greater than the CO 2 that is let out. Author talks of how burning of forests could let out all the abosrbed CO 2 , he equates it to 10 years of CO 2 emission in one shot. O f course this also means , we cut out the possbility of future absorption of CO 2 by forests.
He is quite clear that as a class , politicians get attracted not by long term interests of the society but the short term interests of society where immediate benefits can be shown and get votes. He looks at some method of incentive and market mechanics being built in in such a way that greening bEcomes not just the fad of some environmentalists but becomes a commercially sensible option.
He is looking at good initial funding and encouragement by US government and in fact all Governments to make sure that the interested producers long interest in protected . Also investment in technologoes to reduce the cost of generation of renewal energy sources.
The author also talks of how a gradually gathering people's movement is also necessary to have the change in tide of political and Governmental thinking. Most of revolutionary changes happen on the bedrock of people's movements.
Author's point about hwo the future costs to the society in using fossil fuesl is not factored in.
Author extensively talks of China's energy requirement and how critical it is to make sure that China becomes an early convert (internally ) or the equation could go awry.
Good book, gauthor given to extreme examples , incremental amd marginal examples do not bring out the point forcefully. As long credibility is not lost, it is okay.
