C an much sex be behind global climate change? At least that is what very many persons including some scientists are saying. One could argue that has been going on ever since Eve ate the apple of the forbidden tree but then in those days antibiotics and vaccines were not around. The current action combined with reduced mortality rates have led to the planet's population rising to around seven Billion. Collect a bunch of persons in a room and see how it warms up! Each body generates heat continuously. Could that be happening on a planet wide scale? However that is not what the scientists are saying. Instead what happens is that as humans develop they begin using things like cars and electricity. All those require burning fossil fuels and that adds direct heat to the planet as well as carbon emissions that are greenhouse gases. As long as it was only a few hundred million Americans and Europeans doing that it was OK, but now we have a few billion Indians and Chinese beg

Climate change through Logging, Oil on canvas by Ashok There are two facts about climate change that most people know and one that most do not know. First the two known facts: Most scientists believe that some climate change is happening Most scientists think that climate change is man made This Scientist fully agrees with the above two facts. Now the one fact that most people do not know but this author/scientist believes to be a fact is: Climate change is happening and it is most probably due to human activity i.e it is man made but the most likely cause is not increase of carbon emissions as assumed by lay persons and suggested by some scientists too. It appears to be primarily due to increasing deforestation on the planet and perhaps to some extent due to increasing concrete and cement based urbanization (even where it is unnecessary such as footpaths and surroundings of buildings that are at best left green, unpaved, pebbled etc.)

Workers inside a Refinery Ever since it was decided to shift the Rajasthan refinery project from Leelala to Pachpadra many persons in Rajasthan connected to or from the Leelala region are protesting. There is an amicable solution to solve the problem that involves the following steps Announce the acquisition of land from Leelala region for refinery at reasonable rates from farmers willing to give the land Consolidate the acquired land while returning land of small disconnected patches with some compensation for inconvenience caused Asses the size of the refinery that can be set up on available land Float international tender for a second refinery on available land with fast and speedy processing Set up a second refinery at Leelala while not disturbing plans of ongoing Pachpadra refinery Setting up of two refineries will make everyone happy, improve efficiency and technology because of competition and improve the econ

There is a nice and brief article on the internet on Properties of steam and water at this link . Another excellent resource that explains briefly what a steam table is .engineersedge    If you are a student of thermodynamics then you would need your own copy of Steam tables. I recommend my own available at most online book stores including Amazon. These were developed by me since I have taught thermodynamics to engineers at the Indian Institute of technology, The University of British Columbia in Canada and at the University of Mosul in Iraq. In case you think they are expensive, pool in with some friends, get a single copy and make photocopies for the rest. I know it is copyright stuff but I own the copy right and I assure you I will never complain against a student who photocopies these tables :). Best wishes for your course. You will find the tables at the following link http://www.amazon.com/Steam-Property-Tables-Thermodynamic-Properties/dp/147923026X
