The article, “Melting Glaciers blamed for subtle slowing of Earth’s Rotation,” by Will Dunham, talks about how the melting of glaciers appears to be slightly slowing down the Earth 's rotation. Also about how the melting of glaciers are due to the world 's temperatures. At the beginning of the article William Dunham states that the driving force behind the discernible change in the Earth 's rotation is measured by satellites and astronomical methods. Also that the global sea level rise is fuelled by an influx of meltwater into the oceans from glaciers. A geophysicist, Jerry Mitrovica, explained more on this problem when he said, “Because glaciers are at high latitudes, when they melt they redistribute water from these high latitudes towards
The glaciers cover about 10 percent of the Earth it forms in the Canada, Greenland, and Antarctica (United States). There are giant ice sheets that cover most of the continent and the depth of the ice sheets range in different thickness ranging from hundreds of feet to thousands of feet. The glaciers have made an enormous impact on the Rocky Mountains by digging through the ground, depositing the sediment that it has picked up, and creating lakes. http://www.encyclopedia.com/topic/Rocky_Mountains.aspx Glacier erosion When glaciers scrapes across the ground moving dirt and creating deep valleys, it is a process called glacier erosion. It is believed that the glacial erosion has caused the Rocky Mountains to increase its height.
Unfortunately, humans, just like Lennie, are taking it too far by causing the opposite effect. Humans essentially are over-warming the earth with rising emissions and the use of crude sources of energy. As a result, the ice caps would melt. If the ice caps were to melt, the sea level would rise exponentially, which would affect modern coastal cities and arctic wildlife. The consequences as a result of our actions could be devastating.
Finally, the sea level rise and flooding is a big problem people-wise. Flooding causes millions in damage that sometimes cannot be reversed. Flooding is encouraged by climate change because of the increase in moisture trapped in the air, and rain happening earlier in the year and falling on still frozen ground. Houses being destroyed by increased water also leave people homeless and cost a lot to fix. Climate change will cause more natural disasters such as flooding, tornadoes and
Some experts projected that combination of increase in temperature and water withdrawals, water flows in winter would less than 100 ft3 per seconds in the future. Also, they predicted that water flows in the oil sands region would decrease by 8% to 26% when an average temperature increase 3 C° by
Arctic ice reflects 80 percent of the sunlight back into space. As sea ice melts there will be more sunlight hit the ocean which increase the temperature of the ocean and cause raise of sea level. Satellite observations show that Arctic sea ice concentrations have significantly decreased over the last 25 years. Submarine observations also suggest that the Arctic ice pack has thinned dramatically in the last 20 to 30 years. As the sea ice melts the sea level increase.
Earth’s climate has been changing over the last few decades, with the global temperatures rising at a high rate (Corell, 2006). Some of these climate changes are due to natural causes, although the strength at which temperatures are rising indicates human influences, such as increased carbon dioxide emission, as well as other greenhouse gases. Climate change particularly affects the Arctic region, where warmer temperatures are causing decrease in sea ice extent and thickness, permafrost thawing, coastal erosion, changes in ice sheets and shelves, and consequently, changes in the distribution and reproduction rates of Arctic species (Corell, 2006). Warmer temperatures have led to increased melting of glaciers and sea ice, and shortening of
When large storms hit land with these increased sea levels it causes large storm surges that can destroy anything in its paths. If temperatures continue to rise other natural disasters could occur ("Global Warming Will Produce More Katrina-Like Storms"). A warmer wetter atmosphere could spawn more tropical storms and there will be floods in places that do not get much rainfall. Humans could prevent these problems if they were to cut down on the use of fossil fuels and use more renewable energy. Renewable energy consists of wind, solar, and lunar power.
The effects of the climate change are undeniable in the scientific research. The Intergovernmental Panel on Climate Change and other meteorological organizations measures the temperature of the earth on the daily basis and has indicated the potential increase. Furthermore, the dramatic decline in ice and glaciers in the North and South Pole verify the rising temperature and its impact on the sea level. It should be noted that from last decade, the sea level has been increased due to melting of the ice that ocean currently pose a threat (Shrestha, Babel, & Pandey,
One of the affects would be the rising of the ocean level. The ice which has been melts, floods down into the ocean. The glaciers and ice sheets are covering about 10% of the world 's land area. The Mount Kilimanjaro holds one of the largest glaciers of the world. However, the capacity of the glacier has been decreased by 80% over the past century.
Polar ice caps are melting, sea level is rising, wet places are drying, cold places are warmer, all of these things are caused by Global Warming. What is Global Warming? you might ask. Well Global Warming is a slow rising of the earth’s overall temperature. This means that it isn’t a drastic change and the world’s climate is getting heated up in a week.
Consequences of global warming Global warming is causing the glaciers to melt specially in rise in sea level would destroy the plants and other species as the area would get over-flooded. The animals would die from hunger due to the deterioration of forests and plants. Ultimately the people who have survived the flood and heat would suffer at the hands of hunger as the only two sources of food we have would get destroyed due to global warming.
Now another natural cause of global warming is the rising of the seas. The biggest reason for sea level rising is that global warming is causing the air to be warmer and that 's causing glaciers and ice-caps to melt. Sea level rise would affect about 11 out of the 15 biggest cities in the world. The reason this is happening because gases are being released into the atmosphere which is causing the temperatures to rise, which causes the seas to rise. Sea level rising means more money that we have to spend for people living on the coastlines because coastal populations are growing and people are crowding into coastal areas and that area could be underwater in a few years if sea levels keep rising how they have been.
According to the NOAA tide data the sea rises Between 0.8 to 3.3 mm Per year with an average rate of 1.8 per year. Greenland and Antarctica together hold enough ice, that if it all melted sea levels would rise more than 80 meters. Rising tide data published by NOAA has suggested that low lying coastal areas will be affected the most by this problem. Places Like the low lying parts of the Netherlands, Brazil, Egypt, America, Japan, India, Indonesia, Vietnam and
