’s orbit‚ mountain-building and continental drift‚ and changes in greenhouse gas concentrations. There are a variety of climate change feedbacks that can either amplify or diminish the initial forcing. Some parts of the climate system‚ such as the oceans and ice caps‚ respond slowly in reaction to climate forcings‚ while others respond more quickly.1

impacts that global warming is having on the earth. Studies have shown that the arctic sea ice is decreasing in size yearly. The red outline in the picture to the left shows how large the Polar Ice Cap was in 1979. The white are in the picture is how big the Polar Ice Cap currently is‚ that’s a significant decrease over just thirty five years. The thinner the ice gets the faster it melts. Besides the shrinking‚ the arctic sea ice is also forming later and later every year. This is directly impacting

The Arctic Tundra is among Earth’s coldest‚ harshest biomes. Tundra ecosystems are treeless regions found in the Arctic and on tops of mountains. The Arctic tundra is mostly located in the Northern Hemisphere but in the Southern Hemisphere‚ it can be located on islands off of the coast of Antarctica. The high mountain tops of North

Task 1 Can polar bears and people coexist? Polar bears are the largest land predator on earth today. They live in the Arctic area‚ surrounded by the northern nations like Norway‚ Greenland and Canada. The effects of global warming have caused the temperatures to rise‚ which have led the Arctic ice to melt. Because the polar bears’ territory is shrinking‚ they are forced to hunt further inland. They usually hunt on the sea ice‚ but they cannot do that now. A polar bear can starve for months‚ but

different ways in the ocean. The first is by thermogenesis‚ which is where methane is produced on the seafloor when organic material is broken down by heat. The other is Biogenic‚ which is where microorganisms eat organic material and leave behind methane as a waste product. ("Methane in the Ocean") There are large amounts of frozen Methane in the Arctic Ocean. ("Methane Emissions from the Arctic Ocean: Image of the Day") Methanogenic bacteria survive in anaerobic areas deep in the ocean. This methane is

realize the how global warming affects the environment. The purpose of this paper is to discuss the effects of global warming on the weather‚ overall health‚ and on wildlife. Global Warming on Weather Patterns The increase in water temperatures in the ocean has generated more energy into what used to be normal tropical storms‚ causing them not only to be more frequent‚ but a lot stronger and sometimes very destructive. As we have seen within the last decade‚ there has been a marked increase in the number

branch of Earth science that studies the ocean. It covers a wide range of topics‚ including marine organisms and ecosystem dynamics; ocean currents‚ waves‚ and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers blend to further knowledge of the world ocean and understanding of processes within it:

the global warming‚ Canadian governments and schools have devoted to take actions on climate change. Climate change refers to a change in the weather which can be an environmental problem‚ such as the sea level rising‚ more warming over land than oceans‚ and more hot days and nights. In the past century‚ climate change was consistent with greenhouse gases increase (Philippe & Kool‚ 2000‚ p.16). According to Lemieux and Scott (2005‚ p. 385)‚ anthropogenic climate warming is threaten to global
