According to the International World Wildlife Fund (WWF) species from the tropics to the poles are at risk. Many species may be unable to move to new areas quickly enough to survive changes that rising temperatures will bring to their historic habitats. 1/5th of the world’s most vulnerable natural areas may be facing a “catastrophic”… Continue reading Impact of Climate Change on Ecosystem and Biodiversity

Climate change is expected to exacerbate current stresses on water resources. By 2020, between 75 and 250 million people are projected to be exposed to increased water stress due to climate change. Warming has resulted in decline in mountain glaciers and snow cover in both hemispheres and this is projected to accelerate throughout the 21st… Continue reading Impact of Climate Change on Water Bodies and water insecurity

Land degradation means reduction in the potential of the land to produce benefits from a particular land use under a specified form of land management. Changes in climate are recognized as one of the major factors responsible for land degradation affecting sustained development. Land degradation encompasses change in chemical, physical and biological property of the… Continue reading Impact of Climate Change on Soil and Land Degradation

Low production: Rise in coconut yields (with some exceptions); reduced fruit and vegetable production. Negative impacts on livestock: Livestock of tropical regions would become more prone to infectious and parasitic diseases. Livestock’s productivity would decline. Indigenous breeds of India like Rathi, Tharparkar, Red Sindhi, etc. would be at danger. Regional impact: According to the Turn… Continue reading Impact of Climate Change on Agriculture

Burning of fossil fuels: People drive cars. Heat and cool their houses. People cook food. All those activities take energy. Burning coal, oil, and gas to generate energy ? Burning these things emit gases into the air. The gases cause the air to heat up. This can change the climate of a place In its… Continue reading CAUSES OF CLIMATE CHANGE: Anthropogenic

Solar irradiance Changes in the sun’s energy output would cause the climate to change, since the sun is the fundamental source of energy that drives our climate system. Studies show that solar variability has played a role in past climate changes, a decrease in solar activity is thought to have triggered the Little Ice Age… Continue reading CAUSES OF CLIMATE CHANGE: Natural

Greenhouse Effect The greenhouse effect refers to the rise in the global average temperature of the earth. The greenhouse effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things… Continue reading All about Greenhouse gases and Effect

Surface water includes river, lake and pond water but here only river water pollution is discussed as lake water pollution is discussed separately.   Major River Water Pollutants: Sewage Wastes Infectious agents include germs and viruses which causes several types of diseases like typhoid, dysentery, cholera, etc. Plants nutrients and dissolved substances e.g. chemical fertilizers,… Continue reading Surface (River) Water Pollution
