Now, with companies trying to consolidate their positions and finding effective means of sustaining growth, the management of real estate has emerged as one of the key challenges for the corporate sector. The economic slowdown in these markets have resulted in increasing pressures on the margins of companies operating out of India, which in turn has led to the companies looking to cut costs through reducing expenditure on the real estate segment.
There may also be changes in the frequency and intensity of extreme weather events, though it is difficult to connect specific events to global warming. Other effects may include changes in agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors.
Sahel desertification informative coursework essay scientific uncertainties include the exact degree of climate change expected in the future, and how changes will vary from region to region around the globe. There is ongoing political and public debate regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences.
Most national governments have signed and ratified the Kyoto Protocol aimed at combating greenhouse gas emissions. The detailed causes of the recent warming remain an active field of research, but the scientific consensus identifies increased levels of greenhouse gases due to human activity as the main influence.
This attribution is clearest for the most recent 50 years, for which the most detailed data are available.
Contrasting with the scientific consensus, other hypotheses have been proposed to explain some of the observed increase in global temperatures, including: Climate commitment studies indicate that even if greenhouse gases were stabilized at present day levels, a further warming of about 0.
Greenhouse effect [pic] [pic] Recent increases in atmospheric carbon dioxide CO2. The greenhouse effect was discovered by Joseph Fourier in and was first investigated quantitatively by Svante Arrhenius in These levels are considerably higher than at any time during the lastyears, the period for which reliable data has been extracted from ice cores.
From less direct geological evidence it is believed that CO2 values this high were last attained 20 million years ago. The rest of the anthropogenic emissions are predominantly due to land-use change, especially deforestation. The rate of rise will depend on uncertain economic, sociological, technological, natural developments, but may be ultimately limited by the availability of fossil fuels.
One of the most pronounced feedback effects relates to the evaporation of water. The warming causes more water to be evaporated into the atmosphere. Since water vapor itself acts as a greenhouse gas, this causes still more warming; the warming causes more water vapor to be evaporated, and so forth until a new dynamic equilibrium concentration of water vapor is reached at a slight increase in humidity and with a much larger greenhouse effect than that due to CO2 alone.
Feedback effects due to clouds are an area of ongoing research and debate. Seen from below, clouds absorb infrared radiation and so exert a warming effect. Seen from above, the same clouds reflect sunlight and so exert a cooling effect.
Increased global water vapor concentration may or may not cause an increase in global average cloud cover.
The net effect of clouds thus has not been well modeled, however, cloud feedback is second only to water vapor feedback and is positive in all the models that contributed to the IPCC Fourth Assessment Report. As the ice melts, land or open water takes its place. Both land and open water are on average less reflective than ice, and thus absorb more solar radiation.
This causes more warming, which in turn causes more melting, and this cycle continues. Positive feedback due to release of CO2 and CH4 from thawing permafrost is an additional mechanism contributing to warming.
Possible positive feedback due to CH4 release from melting seabed ices is a further mechanism to be considered. Effects of global warming From Wikipedia, the free encyclopedia Jump to: Global warming [pic] [pic] The net impact of global warming so far has been modest, but near-future effects are likely to become significantly negative, with large-scale extreme impacts possible by the end of the century.
The predicted effects for the environment and for human life are numerous and varied. The main effect is an increasing global average temperature. From this flow a variety of resulting effects, namely, rising sea levels, altered patterns of agriculture, increased extreme weather events, and the expansion of the range of tropical diseases.
In some cases, the effects may already be occurring, although it is generally difficult to attribute specific natural phenomena to long-term global warming.
Scientific and business groups in individual countries are also producing reports on the effects of global warming on their nation, such as in Australia. Proposed responses to the effects of global warming include mitigation and adaptation. Examples of projected climate changes include: The likelihood, magnitude, and timing of many of these changes is uncertain.Germany doesn't only want refugees, it actually really needs them.
Ecological Crisis In Sahel Essay The Sahel region is the semi-arid part of western and north-central Africa that is located between the Sahara in the north, and the humid savannah of the south— much of it being in what was formerly French West Africa.
Sahel Desertification - Informative coursework. The most effective solution to the desertification in the Sahel is to grow perennials in areas and recultivate a strong and efficient green belt.
People in the Sahel are a victim of desertification in these dry lands. This process most commonly occurs in arid and semi-arid environments, the Sahel region in Africa is one of the worst r-bridal.comtes suggest that 35% of the earth’s land surface is at risk, and the livelihoods of million people are directly affected.
75% of the world’s drier lands – 45,, square kilometers are affected by desertification, and every year 6,, hectares of agricultural land are lost and .
