What Is Global Warming? ByRAM KRISHNA SAH Photo: David McNew/Getty Images The term "global warming" refers to the increase in the average temperature of global surface air and oceans since about 1950, and to continuing increases in those temperatures. Another term for "global warming" is "climate change." Per the Intergovernmental Panel on Climate Change , which shared the 2007 Nobel Peace with Al Gore for landmark work on climate change: "The global surface temperature is an estimate of the global mean surface air temperature. However, for changes over time, only anomalies... are used, most commonly based on the area-weighted global average of the sea surface temperature anomaly and land surface air temperature anomaly." Per Wikipedia, "The Intergovernmental Panel on Climate Change (IPCC) concludes that... greenhouse gases are responsible for most of the observed temperature increase since the middle of the t...
What is wasteland reclamation? and how it related to environment studies? Best Answ Reclaiming lands that have been laid waste in an extraction or industrial process is "wasteland reclamation." Strip-mining coal produces wastelands. Using chemicals in an industrial process, then dumping the used chemicals either on the land or into a stream creates wastelands. Or releasing chemicals into the air in an industrial process can create waste lands. Sometimes, just running an industrial process, particularly when there is no regulation of its wastes, can create wastelands. And finally, nuclear accidents can create wastelands. You might want to research Copperhill, Tennessee, as a place that underwent reclamation and regained a life. You might want to research "strip mining" as a method of creating wastelands in the first place, as well as "Chernobyl," the site of a nuclear accident in Russia, "Three Mile Island," ...
.WIND ENERGY Wind Energy is generated by harnessing the kinetic energy of atmospheric air. Wind Energy has had been in use for centuries for several other purposes such as sailing, irrigation and for grinding grain. Wind power systems transform kinetic energy of the wind into useful sources of power. During ancient times, wind power systems were used for both milling and irrigation. It was during the early years of the 20th century that wind power was started to be harnessed for generation of electricity. Windmills have also been used in several countries to pump water. Wind turbines work by transforming the Wind Energy into mechanical power that can be used for conversion to electricity or for other mechanical purposes like grinding. Wind turbines are used either as stand-alone units or in groups known as Wind Farms. Small-sized wind turbines, known as aero generators are used for charging large-sized batteries. More than 80% of the global Wind Energy capacity is installed...

Types of water pollution There are many types of water pollution because water comes from many sources. Here are a few types of water pollution: 1. Nutrients Pollution Some wastewater, fertilizers and sewage contain high levels of nutrients. If they end up in water bodies, they encourage algae and weed growth in the water. This will make the water undrinkable, and even clog filters. Too much algae will also use up all the oxygen in the water, and other water organisms in the water will die out of oxygen from starvation. 2. Surface water pollution Surface water includes natural water found on the earth's surface, like rivers, lakes, lagoons and oceans. Hazardous substances coming into contact with this surface water, dissolving or mixing physically with the water can be called surface water pollution. 3. Oxygen Depleting Water bodies have micro-organisms. These include aerobic and anaerobic organisms. When to much biodegradable matter (things that easily decay) end up in wat...
