The Upsala glacier is the third largest Southern Patagonian (Patagonia comprises the southern most region of South America) Ice Field and covers an area of 800 square kilometers. It is one of the largest glaciers located in the Los Glaciares National Park, Argentina. This glacier terminates in the northern part of Lake Argentino. Its retreat has not been directly linked to global warming. The photographs show the retreat of the glacier from January 2001 to January 2004.
The San Quintín Glacier is the largest outflow glacier of the Northern Patagonian Ice Field located in southern region of Chile. As seen in the photographs, this glacier appears to be retreating and losing mass in recent years.
The Larsen ice shelf is situated in the north-west part of the Weddell Sea. It consist of three ice-shelves, Larsen A which is the smallest, Larsen B and Larsen C, the largest. Larsen A disintegrated in January 1995 and Larsen B in January 2002. About 3,250 square km of the Larsen B ice shelf area disintegrated in a 35 day period beginning January 31, 2002 (National Snow and Ice data center). These events are being linked to global warming and the rate of warming has been 0.5 degrees Celsius per decade since 1940s in the Antarctic Peninsula.

Gangotri glacier is situated in the Uttar Kashi district of the Uttarakhand state of India. It is the largest one in the Himalaya and is 30.2 km long and 0.5-2.5 km wide. It has been receding since 1780 and started retreating rapidly after 1971. However, its retreat has not been directly linked to global warming. The blue contour lines show the recession of the glacier over time.
These true color images show a large portion of the west coast of Greenland. The grey colored ice between the bare ground (on the left) and the solid white (on the right) represents the melt zone. This area indicates that the surface of the ice sheet is saturated with water. The meltwater ponds are seen as tiny blue dots scattered in the area. From 2001-2003 the melting significantly increased and extended further south.
Methods of mitigating global warming include Conservation Reduce energy needs, such as electrical usage, petroleum usage, reduced packaging Recycling, which uses less energy to produce products compared to Another way to reduce carbon emissions is to use alternate energy sources, such as Nuclear Wind Geothermal Hydroelectric Solar Fusion?
Scientists agree that the burning of fossil fuels is causing global warming. Since these fuels are burned for energy, and everyone uses energy, everyone can help stop global warming just by using less energy or energy from renewable sources!
Global warming pro. amit
Greenhouse gases , such as carbon dioxide, water vapor, nitrous oxide, and methane, trap heat and sunlight in the earth’s atmosphere, increasing the temperature.
Warming of the earth through carbon dioxide (CO2) being pumped into the atmosphere. Then the gases trap heat like the glass in a greenhouse. This is where the term “greenhouse effect” came from.
Tropical Forests & Grass Lands will disappear ,Ground water level will go down and heat will increase. Soil Warming
Sea Warming leads to Wind Warming Wind Warming will make cyclones, hurricanes and typhoons more violent and frequent.
