Some time ago there was tough fight for gases and fuels below the earth. People or companies take possession of natural resources and exploit them at will and Governments get pittance while the companies make billions from extracting natural resources in form of oil , coal, minerals or forests These companies belong to private owners whose main concern is to gain profits. Mankind is the sufferer Who has right to sell reserves of minerals , oil, gas to private companies or exploit themselves unhindered because two third of the mankind is too young to understand anything and rest are powerless…

Many a times I feel sad that  questions are  being raised about plantation of trees and reducing the global warming.Other day people have pictures of their houses those houses which have plants in their surroundings having cooling effect in the environment and reducing expenditure on air conditioner and its emissions . Its simple logic that if each house plants enough trees to keep their house cool and if each of the 8 billion people plant one tree in their house hold or in adjoining area global warming will be thing of the past ? Can we just give a try . However the question is…

Why Cow-Driven Global Warming Is A Load Of Bull All animals breathe in air and then breathe it out again.  This astounding fact, seemingly new to some web users, has nothing whatsoever to do with global warming. Some people are still seemingly astonished to find that cows breathe out air deficient in oxygen and with a surfeit of CO2.  They eagerly report this brand new finding to a breathless crowd of eager supporters of any 'proof' that humans are not responsible for the inexorable rise in global CO2.Edit:  in response to a perfectly sound criticism from Michael White, in…

We can do a lot of things to reduce the greenhouse gas emissions often blamed for climate change, but cutting back on consumption of meat and dairy products isn't one of them, according to a report presented at the National Meeting of the American Chemical Society. Giving cows and pigs a bum rap is not only scientifically inaccurate, but also distracts society from embracing effective solutions to global climate change, says UC Davis Professor of Animal Science Frank Mitloehner. He noted that the notion is becoming deeply rooted in efforts to curb global warming, citing campaigns for "…

Understanding Climate : #3 - Tilting At Seasons The tilt of the earth's axis gives us our seasons. But not in an obvious way. Understanding climate science requires a cross-disciplinary approach.  This is the second part of the mainly astronomical section.  In part 2, I introduced the idea of, in a manner of speaking, building a model of our earth-moon-sun system.  Here I continue with a discussion of seasons and their primary astronomical causes.  New readers may wish to start at Understanding Climate : #1 - Components Of Climate. This is the second chunk of the…

Global meat production has tripled in the past three decades and could double its present level by 2050, according to a new report on the livestock industry by an international team of scientists and policy experts led by Standford University. If not addressed, the impact of this 'livestock revolution' is likely to have significant consequences for human health, the environment and the global economy. the report concludes that more than 1.7 billion animals are used in livestock production worldwide and occupy more than one-fourth of the Earth's land. Production of animal feed consumes about…

"First of all, FACT agrees that many unsubstantiated claims have been made on jatropha, such as high yields on marginal soils, low water and nutrient requirements, and high resistance to pests and diseases. These claims have already been falsified some years ago 2 but it seems difficult to convince all practitioners and policy makers of the facts. Despite the slowly increasing body of knowledge on jatropha cultivation methods, the agronomy of the plant is still largely unknown, and the risks of disappointing yields are substantial. Furthermore, the report describes how large biofuel…

Understanding Climate : #2 - Earth Air Water Fire Climate science is a cross-disciplinary study.  I have listed some of the disciplines in Understanding Climate : #1 - Components Of Climate and have hinted at others in Mother Earth Cycles To Work.  In this article I shall introduce some astronomical scale inputs to our global climate system.  I shall be developing the ideas in what I hope will be easily digested chunks.  This is the first chunk of the astronomy section. What astronomy teaches us about our homeworldOur planet Earth gets by far the greatest part of its…

Understanding Climate : #1 - Components Of Climate The difference between weather and climate Weather is what you see every day: whatever the sky is doing, that is your local weather.  Sun, rain, hail, snow, thunder and lightning - all these are weather.  Fluffy white clouds, thunderheads, tornados, hurricanes - all are weather. Wherever you live in the world you can pretty much guess what sort of weather you will get season by season and what weather you won't get.  The range of your local weather throughout the year doesn't change much from year to year.  If you live in…
