What is the big deal about climate change?

The Copenhagen summit on climate change is about to begin shortly. As usual the bickering between nations and between "developed" and "developing" nations is going on. The issue is that the developing nations especially India and China have to cut greenhouse gas emissions along with the developed countries. The rationale is that the emissions of India and China are increasing at a rapid pace. Even if the developed countries cut greenhouse gas emissions it will be more than offset by the emissions of the developing world defeating the whole purpose of fighting climate change. The rationale seems logical enough?
Sadly, climate change has become a political tool for the west to impose its controls over the emerging economies. Since much of the world media including our own Indian english channels are controlled by the west, it becomes a tool to control the public opinion in most of the world including India. Here are some "facts" about climate change you probably did not know
  1. The world's climate has been changing ever since Earth was formed 4.5 billion years ago. It has been happening even during the existence of human beings. When man was still primitive Sahara was not a desert but grassland and forest. River Saraswati probably flowed in Rajasthan. Men were hunting woolly mammoths during the last Ice Age. There was a "little" ice age in the 16th century. There are stories of crops being grown in Greenland by the Vikings suggesting that Earth may have been warmer. Although there is evidence that the present warming is "anthropogenic" it is still not conclusively proven.
  2. The common perception about global warming is that coastal cities are going to get flooded and there will be huge losses of life. According to even the worst case scenario postulated by IPCC the global sea level rise will not exceed 1m (3.3ft) by year 2100. I think gradual rise of 3ft in 90 years will not be dangerous to anybody.
  3. Thirdly, contrary to what media portrays the glaciers in the Himalayas are growing rather than shrinking. Higher temperatures lead to higher precipitation which offsets the melt loss due to warming. The Siachen glacier on which the Indian Army is stationed is an example. 
  4. Fourthly, even if the Global warming is "anthropogenic" reducing emissions will not help in any way except to slow the warming. To stop and to reverse warming you need to have negative emissions which is very difficult to achieve in present circumstances.
Whether global warming is real or not, whether it is actually harmful or not is a different issue. The worst part is how it has been used as a tool to erect the barriers of protectionism against the emerging economies. EU is mulling a carbon tax against countries which do not cut emissions. After ruining many nations using the IMF as a tool and destroying local industries across the world, now US and Europe are afraid to face competition from the so called "Third World". It speaks volumes about the hypocrisy of the west and US in particular. India has been made the villain of the whole show when the per capita emission in India is just 2 tons of CO2 per year wheras in US it is 20tons. Out of the 2 tons 200kg is from breathing alone! Probably one day they will tell that Indians should stop breathing and die because they are emitting greenhouse gases!

CAT Funda

Thousands of people attend tution classes for CAT every year, hoping that they would be able to crack the exam. They also pay thousands of rupees in tution fees, books and MOCK CATs. If you take the money spent on CAT coaching every year, you probably would be able to set up a new IIM every year!!
Anyway since I have "cracked"  or "belled" the CAT I would like to share some of the tips for free.
There are basically three steps to successfully crack CAT
  1. Accuracy: You have to be extremely accurate while answering CAT as CAT has both negative marks and limited time to answer the questions, getting a question wrong would imply that not only did you lose out on marks you have already got, you are also wasting time which could have potentially been used for answering an other question. In other words "opportunity cost" of a wrong answer in CAT is very high. 
  2. Selection: Selection is another very important area when answering CAT. You have to attempt(and get right) all the easy and moderate questions and leave out all the hard questions. The definitions of easy and moderate are quite subjective and it depends on an individual. In a general sense any question which can be solved within 4 minutes by an average person can be considered to be easy. Easy questions are questions in your comfort area. 
  3. Strategy: Strategy is another important area and it is the most misunderstood area. Firstly, people do not understand what strategy is all about and they devise elaborate plans which fall flat under examination pressure. Secondly, the strategy they devise will be inappropriate or flawed. There is no general strategy applicable to everyone. You have to devise a strategy of your own. But there are a few important points that would aid in developing an effective strategy. 
    • The strategy should be simple: A simple strategy is one which can be easily applied in an examination scenario and which is robust to changes in paper pattern. Some people have elaborate plans like attempt DI for first 15 mins, then move to Quant, come back to DI, go to verbal, come back to Quant etc etc. If there is a major change in difficulty level or change in paper pattern, there is a good chance that the whole strategy will fail
    • The strategy should reflect your strengths and weaknesses: You should thoroughly know your strengths and weaknesses before you attempt the real CAT. Although it sounds like a management cliche, all it means that you should have a good idea as to what areas you are strong in and what areas you are weak in. You have to score heavily in your strong areas and you have to minimize losses in your weak areas. If you are strong in Geometry and weak in number theory, you should ideally attempt all the questions in Geometry and attempt the easy questions in number theory.
    • The strategy should reflect your priorities: Different IIMs have different cutoffs and the admission procedures keep changing all the time. The best approach would be to cross cutoff(96 %ile) in all the sections and then maximize the overall score. However some people may be really weak in one section. Those people should try to maximize their overall score without bothering too much about cutoffs. They have to try to get a minimum threshold like (85%ile) in their weak section but should maximize their overall score. By using this strategy they can atleast get a few IIM calls and get calls from other good institutes rather than getting no calls at all.
 That is it for now. If I have the time or the inclination, I shall post more
