Climate is changing, carbon dioxide is increasing, and Earth is getting hotter. by Dr. Nitish Priyadarshi Mumbai floods First it was Bombay floods, then Kosi floods, Punjab floods, Rajasthan floods, Leh floods, Jharkhand drought (all in India). Now it is Paksitan floods, China flash floods and landslides, boiling of Moscow, forest fires in Russia, Bolivia and Portugal, and there are lots more to say and write. Millions affected, thousands died, no ending disaster. Climate of the world is changing. What would you think? Yes its climate change or in other broad definition its global warming. If we take the case of drought in Jharkhand State of India, it is very unusual. Other than some pockets of the state, Jharkhand never passed through severe droughts. Rainfall was sufficient all around the year. But from last one year rainfall pattern has changed. Farmers are still waiting for the sufficient rainfall. Agriculture scientists are worried. Monsoon Clouds have changed their way from Bay ...

Can we predict effects of climate change with accuracy? by Dr. Nitish Priyadarshi Recently all the newspaper of world was heated up with the discussions about the so called glaciers melting of Himalayas by 2035, from IPCC. Other prediction was about Amazon rain forests. The IPCC maintained that there would be a huge depletion in Amazon rain forests because of lack of precipitation. There are many more predictions given by IPCC which I think that they are over exaggerated and could not be believed. Regarding glaciers melting by 2035, it is now being defended as a minor error (it was originally meant to be 2350, some have clarified). The global warming controversy is a dispute regarding the nature, causes, and consequences of global warming. The disputed issues include the causes of increased global average air temperature, especially since the mid-20th century, whether this warming trend is unprecedented or within normal climatic variations, whether humankind has contributed significant...

CO2 Data Set: Original data file created by NOAA on Wednesday February 10, 2010 (10:13:56) Measuring Location: Mauna Loa Observatory , Hawaii Data Source: Earth Systems Research Laboratory (ESRL) / National Oceanic and Atmospheric Administration (NOAA) Why is CO2 significant? Carbon dioxide (CO2) is the chief greenhouse gas that results from human activities and causes global warming and climate change. To see whether enough is being done at the moment to solve these global problems, there is no single indicator as complete and current as the monthly updates for atmospheric CO2 from the Mauna Loa Observatory . What is the current trend? The concentrations of CO2 in the atmosphere are increasing at an accelerating rate from decade to decade. Accelerating from decade to decade. The latest atmospheric CO2 data is consistent with a continuation of this long-standing trend. What level is safe? The upper safety limit for atmospheric CO2 is 350 parts per million (ppm). Atmospheric CO...

Increasing carbon dioxide benefits trees. by Dr. Nitish Priyadarshi Almost 100% of the observed temperature increase over the last 50 years has been due to the increase in the atmosphere of carbon dioxide and other greenhouse gas concentrations like water vapour, methane and ozone.. The largest contributing source of carbon dioxide gas is the burning of fossil fuels. Research says more carbon dioxide more heating of the earth. This is one aspect of the carbon dioxide. Other aspect is its relation with the trees. If we believe on the researches by the scientists, increasing carbon dioxide benefits trees. Scientists from the University of Wisconsin-Madison and the University of Minnesota at Morris have found that increased levels of atmospheric carbon dioxide have led to the rapid growth of certain tree species. The quaking aspen, a popular North America deciduous tree, has seen a 50 percent acceleration in growth over the past 50 years due to increased CO2 levels. Trees are necessary ...

Population Explosion may trigger Global Warming. by Dr. Nitish Priyadarshi Image credit: http://webecoist.com/wp-content/uploads/2008/11/population-explosion1.jpg The earth’s population has nearly doubled since World War II. More babies than ever than ever have been born, but this is only part of the reason for the increase. More and better food and medical care have kept alive many people who would otherwise have died. This enormous increase in the number of people is called ‘population explosion.’ Many experts believe it is the greatest danger facing mankind. A doubled population means a greater drain on the world’s limited resources. Increasing in population size, age and distribution is affecting climate by producing more green house gases, either in the form of automobile or in the form of thermal energy to meet increasing electricity demand. A larger global population means a larger demand for everything--most urgently, energy. The world population is growing by 75 million peo...
