Green house gases

Our aim in the present study was to reveal the features of daily, seasonal and interannual dynamics of water, energy and CO2 exchange in the tropical forest. We accent the factors of seasonal and interannual dynamics of the fluxes.

At present, the global climate change is one of the biggest challenges in front of human race which results mainly from global warming due to an increased concentration of green house gases in the atmosphere. Among the major green house gases, Carbon dioxide and methane contribute maximum toward the global warming. To mitigate the global climate change the reduction in emission of green house gases is necessary. Microorganisms play a crucial role in the regulation and utilization of these gases.

A wheat growth model that includes the direct responses of canopy photosynthesis and transpiration to elevated CO2, and the response of crop growth to water stress has been developed and tested. Sensitivity analyses show that different cultivars have quite different responses to changes in ambient air temperature, ambient CO2 concentration and rainfall. Because crops reach maturity earlier under higher temperature, an increase of 3 oC may not impose further water stress to growth of a wheat crop.

Climate change has become a burning issue in the present century by changing the properties of atmosphere like rainfall, humidity, temperature etc. Green House Gases are having a major share in the climate change, Co2 being an important culprit in the scenario. Due to the increased Co2 concentration, there is an increase in atmospheric temperature, leading to Global Warming. Climate change is nowadays a trending issue in all sectors of agriculture. Researches have been done showing the influence of climate change on hostpatho system.

This paper examines the deep minimum of solar cycle 23 and its potential impact on climate change. In addition, a source region of the solar winds at solar activity minimum, especially in the solar cycle 23, the deepest during the last 500 years, has been studied. Solar activities have had notable effect on palaeoclimatic changes. Contemporary solar activity are so weak and hence expected to cause global cooling. Prevalent global warming, caused by building-up of green-house gases in the troposphere, seems to exceed this solar effect. This paper discusses this issue.

As a conventional treatment process, centrifugal dewatering of sludge required an additional energy of 1,376 kWh per day for recycling, pumping, mixing as well as transporting sludge. The conclusion was that anaerobic digestion can reduce the green-house gases versus conventional dewatering. The results from this research can thus demonstrate the applicability of anaerobic digestion on conversion of waste to energy, looking forward to resource recovery.

The initiative aims to complement the 5 year cyclic plan, the National Medium Term Development Plan (RPJPM) 20102014, as well as the 20 year National Long Term Development Plan (RPJPN) 20052023. The national government has also committed to reduce green house gases though the National Action Plan for Greenhouse Gas (RAN GRK) and Reducing Emissions from Deforestation and Forest Degradation (REDD+). Such plans are expected to be in line with the National Spatial Plan (RTRWN) which is yet to be completed. ...

We are experiencing rapid growth rate of urbanization, motorization and industrialization. Our overwhelming dependence on fossil fuel to drive our daily life and economic activities has led to releasing of various green house gases and air pollutants into the atmosphere resulting in degrading of the quality of air in the urban areas and global problem of climate change. Degrading of the quality of air in the urban areas has put at risk the lives of millions of people under direct threat due to health impacts associated with air pollution.

By inadvertently increasing the concentration of energy-trapping gases in the lower atmosphere, human actions have begun to amplify Earth’s natural green- house effect. The primary challenge facing the world community is to achieve sufficient reduction in greenhouse gas emissions so as to avoid dangerous inter- ference in the climate system. National governments, via the UN Framework Convention on Climate Change (UNFCC), are committed in principle to seeking this outcome.
