Scientists of the Potsdam Institute have found that the pattern of the Indian monsoon is supposed to change under global warming in the future.
Scientists of the Potsdam Institute for Climate Impact Research in the month of June 2013 have found that the pattern of the Indian monsoon is supposed to change under global warming in the future.Research supported with Computer simulations and a comprehensive set of 20 state-of-the-art climate models shows that Indian monsoon daily variability might increase. The ongoing ups-and-downs of Indian monsoon rainfall are likely to increase under warming.
It is found by the Scientist that a 4% to 12% variability change of daily monsoon rainfall in India is to be expected with 1 degree Celsius of warming. There is also a chance of 13% to 50% change in variability will take place if greenhouse gases continue to be emitted unabated. As per the analysis if global warming would be limited to the internationally acknowledged threshold of 2 degrees Celsius of global warming, this would bear the risk of additional day-to-day variability between 8% to 24%.It is important here to note that about 80% of annual rainfall in India occurs during the monsoon season from June through September. Factors that could disturb rainfall regularity include the higher holding capacity of moisture of the warmer air, but also more complex phenomena like cooling in the higher atmosphere which changes current pressure and thereby rainfall patterns.
The researchers focused on the 10 models with the most realistic monsoon pattern - a conservative approach, as these 10 models yield generally lower rates of change. The other 10 models showed higher rates of change.
Internet Emit 830 Million Tonnes of CO2 in Environment Annually: Researchers
The researchers from the Centre for Energy-Efficient Telecommunications (CEET) and Bell Labs in the first week of January 2013 claimed that internet video and associated cloud services including Information Communication and Technology, discharge more than 830 million tonnes of Carbon Dioxide per year. This emission of the CO2 (one of the major green house gas) from the information and communication industry includes about 2 percent of the global CO2 emission annually and it’s expected to double nearly by 2020. Same is the amount shared by the aviation industry in form of emissions.
To control this emission, the researchers have suggested measures like development of accurate and feasible model taking into account the energy use, data traffic and CO2 production in the networks as well as use of other elements in the ICT industry. The researchers from the CEET and Bell Labs following their new models of emissions and energy consumption have suggested three key factors that would help in reduction of the CO2 emissions from the ICT industry and these are efficient usage of facilities, use of energy efficient equipment and use of renewable energy sources. Centre for Energy-Efficient Telecommunications (CEET): Partnership between the Victorian State Government and Alcatel-Lucent, the University of Melbourne is responsible for the formation of CEET.Bell Laboratories: It is a R&D subsidiary of Alcatel-Lucent in Berkeley Heights, United State and is owned by France. Initially, it was a division of American Telephone & Telegraph Company (AT&T Corporation) and was half-owned by its Western Electric manufacturing subsidiary.
IEA Report: Greenhouse Gas Emissions Increasing Instead of Decreasing
A new report released by the International Energy Agencyon on 5 June 2011 stated that despite 20 years of effort, greenhouse gas emissions are increasing instead of decreasing. The IEA report revealed that energy-related carbon emissions topped 30 gigatons in 2010 which is 5 percent more than the previous record in 2008. If the emission increases further, it could lead to catastrophic climate shifts affecting global agriculture and water supplies. Moreover, it will set off more frequent and fierce storms besides causing an increase in sea levels that would endanger coastlines.The IEA report was released ahead of the Bonn summit to debate a new global warming accord taking place from 6 June to 17 June 2011. It should be noted that the World Environment Day is celebrated on 5 June 2011 every year.
Sunderbans Absorb more than Four Crore Tonnes of CO2 to Check Global Warming
According to a study conducted by the University of Calcutta done in the last week of April 2011, The Sunderbans forest plays an important ecological role by absorbing more than four crore tonnes of carbon dioxide from the atmosphere. The Sunderbans have a 2118 square kilometer of forest cover.Mangroves trees absorb carbon for their own needs. Mangroves are important for maintaining ecological balance and can be helpful in dealing with the problem of climate change. CO2 emission is responsible for global warming. Global warming causes the rise of sea levels and temperature which affects agriculture, human health and fishery. The more the number of mangroves will be the more CO2 will be absorbed from the atmosphere.The study was funded by the Union Ministry of Earth Science and the state forest department. It took two years for the study to get completed. The study was done by the varsity’s marine science department. The stududy concluded that out of the total amount of carbon tied in earthbound forms, an estimated 90 percent is stored in the world’s forests.To calculate carbon stocks in three mangrove species namely Avicennia alba, Excoecaria agallocha and Sonneratia apetala in the Sunderbans the researchers used laser beams. The team also estimated carbon content in stem, leaf and branch of the tree.The West Bengal state government may plan to earn carbon credit points and sell them for cash using the carbon emission trading system under the United Nations Framework Convention on Climate Change. Himachal Pradesh state government has already done it. One tone of carbon is valued at 19 dollars in the International market. If the Suderbans are valued in terms of the amount of CO2 it sequesters, the total value will be around 79 billion us dollars.
Report: Arctic Seas Acidifying at a Fast Pace due to Carbon Dioxide Emissions
A new report released in May 2013 claimed that the Arctic Seas are being made more acidic rapidly due to carbon dioxide emissions. Widespread changes in the ocean chemistry of the Arctic region were monitored by the scientists from the Arctic Monitoring and Assessment Programme (AMAP). As per the latest report released by the scientists, if the emissions of carbon dioxide are stopped with immediate effect at this point of time, then also it would take tens of thousands of years for Arctic Ocean chemistry to revert to pre-industrial levels. The scientists have forecasted the effects of the emission will bring in major changes in the marine ecosystem, but there exists an uncertainty over what kind of changes it will be, but will surely Impact the life of many marine creatures, including the commercially valuable fish. CO2 plays a great role in warming of the planet and it helps in making the alkaline water of the oceans more acidic after being absorbed from a Cold water absorbs CO2 faster than compared to water at normal temperature. Thus the ice cold water of Arctic seas becomes more vulnerable. The recent decline of summer sea ice has also helped in exposing the sea surface to atmospheric CO2 to a greater extent. The researchers claim that the water of the Nordic Seas is acidifying to a wide range of depths. Effect of acidifying is faster at surface water than compared in deep waters. Mosaic of different levels of pH has been mapped by the researchers across the region that too based on the scale of change in the local intake of freshwater. A huge decrease of 0.02 per decade in the pH value has been monitored by the team of researchers on the Iceland and Barents seas since 1960s. The estimates made states that the average acidity of the surface ocean waters across the world is 30 percent higher by now, than that before the industrial revolution. Overall as per the scientists and researchers working on the conditions of sea water, it will be very early to predict the exact changes that the sea will witness over the times to come.
