Impact of climate change on Flora: All the plants/tree species requires a specific temperature for their life processes like germination of seed, growth, flowering, fruiting etc. Changes in temperature have changed this cycle. Trees which are unable to adjust to this change are becoming endangered and might get extinct if not saved. Because of the … Read more
Science and economics of climate change Science of climate change The atmosphere functions as a ‘greenhouse’ and insulates the earth from extremes of temperature. The greenhouse effect works in the following manner. Of the incoming short-wave radiation from the sun, one-third is reflected, and the atmosphere, ocean, ice, land, and biota absorb the … Read more
A glance at the world map reveals that most of the desert region is on the western part of the continent for example. Mohave desert in North America, Atacama in Southern America, Namib, Sahara in Africa , Arabian in west Asia. The reasons for such homogeny are: The hot desert lie astride the Horse latitudes … Read more
ELEMENTS OF CLIMATE AND WEATHER Climate is decided by a region’s climate system. A climate system has few major components: the atmosphere, the layer, the cryosphere, and the land surface. The atmosphere is that the most variable a part of the climate system. The composition and movement of gases encompassing the planet … Read more

The Convention, which sets out an agreed framework for dealing with the issue, was negotiated from February 1991 to May 1992 and opened for signature at the June 1992 UN Conference on Environment and Development … Read more
Climate is a major sculptor of landforms. One of generous precipitation often induces extensive erosion through plentiful runoff and stream flow. A moist, cool climate can even favor the formation of glaciers in mountains and high latitudes. Given the proper conditions, these massive ice bodies advance and heavily impact the terrain. A whole slew of … Read more
Abatement of GHGs, particularly CO2 , implies curtailment of energy consumption. Energy is a vital factor of production, and its replacement and/or reduction will entail a shift away from current production methods. If current systems employ efficient production techniques, a change in factor proportions will increase the cost of production, and have an adverse impact … Read more
Concept Definition Carbon sequestration Carbon sequestration is the process of removing carbon from the atmosphere and storing it in a fixed molecule in soil, oceans or plants. Carbon sink An organism or landscape that stores carbon is called a carbon sink. Carbon source An organism or landscape that emits carbon is called a carbon source. Climate change adaptation … Read more
According to economic survey, In a year where temperatures are 1 degree Celsius higher farmer incomes would fall by 6.2 percent during the kharif season and 6 percent during rabi in unirrigated districts. Similarly, in a year when rainfall levels were 100 millimetres less than average, farmer incomes would fall by 15 percent during kharif … Read more
The climate of japan is modified by insularity and also by meeting of the cold and warm ocean currents. It receives adequate rainfall from both the south east monsoon in summer and the north west monsoon in winter. During the north west monsoon dry cold wind from mainland Asia blows. But they gather moisture on … Read more
