Another critical factor in both the formation of thicker, denser clouds and the blocking of sun insolation is aerosols; small particulates such as ash, soot, skin cells, sea salt, sulfates, pollutants and dust. These awards are presented to recognize the efforts of individuals and government and non-government bodies for the popularization of science in the country.
Objectives of Celebrating National Science Day[ edit ] National Science Day is being celebrated every year to widely spread a message about the Importance of science used in the daily life of the people.
The climates of North America and Europe are influenced by the Gulf Stream, a warm ocean current seen boxed in red on the illustration to the left. You can begin your research by exploring the following web pages: The nearest body of open ocean found due east of Manhattan is miles away off the east end of Long Island.
The Gulf Stream acts like a conveyor belt, moving in a circular pattern; a convection current driven by the density difference between warm, tropical salt water versus the colder water found at northern latitudes.
Greenhouse gases trap heat and many locations on Earth will experience an increase in temperatures. The disruption in the Gulf Stream circulation pattern results in a severe global deep freeze which sets the stage for the fictional drama in the film.
Unnikrishnan Nair and Ms. Yet, several times in the film the cyclones are shown moving clockwise. Hurricanes tracks may change ranging farther north and south on warmer water temperatures if, in fact, ocean temperatures change but the calm eye of a cyclonic storm happens over ocean water, not land.
While one degree may not seem all that significant the fact is that such an increase has had an impact on global sea levels due to the melting of Arctic, Antarctic and Greenland Ice. Research CO2 Sequestration, focusing on the following: Over geologic time Earth has gone through several ice ages followed by inter-glacial warming periods.
When molecules of air descend they warm adiabatically due to compression. One possible cause of major periods of glaciation is a change in the tilt of Earth's axis causing a corresponding change in the intensity and location of sun insolation.
However in the movie this law of physics is dismissed by one of the main characters, scientist Jack Hall, when he states that the air in the center of the super cell is "simply descending too quickly". Cloud Cover and Aerosols Higher temperatures increase the amount of cloud cover due to an increase in higher evaporation rates of surface water.
An increase in precipitation, especially at middle and high latitudes, with an increase in river runoff. Scientists are well aware of the delicate balance between 'cloud cover, aerosols, solar radiation and greenhouse gases' and resulting climatic changes.
Drinking water is less available. First, the warm current loses heat to the air, modifying coastal land temperatures. As the Gulf Stream flows from equatorial regions, along the east coast of North America, two things happen. The Antarctic Larsen Ice Sheet has collapsed. Over geologic time Earth has gone through several ice ages followed by inter-glacial warming periods.
