(This article is dedicated to Dr. R.K. Pachauri who died on 13 February 2020) The history of the scientific discovery of climate change dates back to early 19th century and in the late 19th century it was believed by scientists that human made green house gas emissions could alter the climate. Even American inventor Thomas Alva Edison had expressed concern for climate change and had supported renewable energy development in the 1930s. In the 1960s there were countering suggestions that the warming could be cooled off by aerosols produced by human activities. The scientific opinion started building up from the 1970s in favour of theory of global warming. By the 1990s with the advent of supercomputers, climate change was studied theoretically and reinforced with observations on the discoveries made pertaining to Milankovitch theory of the ice ages [1]. Since then the research done has been consolidated in the reports of Intergovernmental Panel on Climate Change (IPCC), which was headed during the years 2002-2015 by a famous Indian Dr. Rajendra K. Pachauri of TERI – The Energy Research Institute, New Delhi. This article is dedicated to Dr. Pachauri who died on 13 February 2020 [2]. Climate change could be natural or manmade. The natural process may take millions of years but the manmade one is very fast within a few centuries. That is where the concern is! At present the phrases “Global Warming” and “Climate Change” are frequently used. It is being argued that the phrases are so much used and people are fed-up and hence the phrases have lost their relevance. A New York based Neuroscience study [3] suggests that the aforementioned words or phrases need to be replaced with newer jargons such as "climate crisis", "environmental destruction," "weather destabilization," or "environmental collapse." When any new phenomenon is disclosed, which is not easy to prove considering the gigantic proportion of it, then there are a lot of ambiguities and criticism leading to formation of lobby groups – one group for it and the other against it with some remaining neutral. The group which opposes the global warming phenomenon has shrunk over the decades. The criticism is not just for the sake of criticism, but it has a lot of self-interests too aided by business lobby groups such as for example oil business and the associated mafia. Everyone knows that the fossil fuels are the culprits in creating global warming gases. The ideal solution would be development of renewable energy sources (of course, Life Cycle Assessment is a Must). Those who have invested heavily in oil exploration and those who are minting huge, how they can so easily accept the concept of global warming? If they do so, then they are finished from doing business. Hence science gets entangled with business cum geopolitics cum professional envy. As explained above, the contradictions of global warming with respect to industrial activities are of one kind. Now let us look into the academic aspects of manpower development to mitigate global warming. Experts-cum-passionate teachers if teach courses such as Ecology & Environment and Environmental Impact Assessment it can create great impact on the young minds. The impact of teaching could be so much that it may create doomsday fear in the young minds. This may also create inner urge within them to save mother earth. The same institute on one end while preaching this philosophy to a bunch of students may breach the philosophy by teaching contrary to it while teaching a bulk of other students, which is a mad race for competition and development. Going back to the memory lane of roughly three decades in premier institutes of India, if one had a glimpse of the future technologies, there used to be information on the variety of emerging technologies but hardly had any mention of the global warming and climate change issues. This proves the contradictions within academic environment. When this theory is not commonly accepted by all how it could lead to an approach in unison to solve the problem. Over the years, the advancement in technology has substantially helped in consolidating the parameters pertaining to global warming and bringing them into the public domain for all to see. The warming has given a clear warning to the humankind “PDCA” or just “P” – “Plan, Do, Check, Act” or “Perish”. The United Nations has taken the issue of Global warming with all seriousness. In line with this warning, some of the countries have taken it as their country’s core value to save mother earth. For example Germany has put in place ambitious renewable energy plan. Accordingly similar other countries have initiated several programmes to mitigate global warming. In the 2016 Paris Summit on Climate Change, honourable Prime Minister of India had proposed that by the year 2030, India would generate 40% of its electrical power through renewables and low carbon footprint fuels. But the term “Global” implies that only a few countries taking corrective measures would not solve the problem. It has to be in unison on a collective global approach. The efforts have to be concentrated similar to what is being done at present in tackling Corona or COVID-19 issue. Take it from me folks, similar to COVID-19, a day would come, when the people would scramble, run helter-skelter with the global warming issue, if they don’t act now. The United Nations since 1992-United Nations Framework Convention on Climate Change (UNFCCC) and subsequent Kyoto Protocol has been issuing very serious statements and warnings in this regard, which of late in the last several months has gone into the backburner due to COVID-19 issue. If the world believes that a global phenomenon could be cured by social distancing and sitting at home, a similar approach on war footing needs to be drafted by the global community to mitigate the Global warming. It is not that, this is an argument for the sake of it but has the proof to substantiate it. Take for example the case of “Ozone Layer depletion and its reformation”. The efforts of United Nations need to be lauded in this regard. It was because of their effort such as Montreal Protocol of 1st January 1989 that the ozone depleting gases such as Freon used in refrigerators are banned from manufacturing since the year 2010. It is heartening to note that the Ozone layer is rebuilding back to its glory. Of course, some scientists may have new theories to contradict the claim of ozone layer rebuilding, but it is happening. If anyone is not convinced, then there is another example to prove the point beyond doubt that acting on solutions do work. Take the example of automobile exhaust emissions control regulations. There is a clear improvement in air quality in cities since the phased implementation of the emission control regulations by countries all over the globe. This nobody can dispute. It was reported in one of the automobile magazines that in the state of California (USA) the exhaust of automobile is cleaner than the air it inhales form the surroundings. Hence the humankind has the solution for the problems they have created. They have to act, act now before it is too late. It may be true that cities like Mangaluru may sink and in that eventuality where would one run – to the Arabian Sea or towards Nitte and the Western Ghats? Yes, Global warming and climate change are real. In changed wordings it could be “Climate Crisis” or “Environmental Collapse” to create neurological effects to act now. (PS: Renewable Energy per se will provide an alternative to mitigate Global Warming. However, LCA proves that all renewables do not mitigate the Warming. Hence a comprehensive study required all over the Globe).
