Where is all this melting ice going? “Sea level rise is caused by two factors related to global warming: the added water coming from the melting of land ice and the expansion of sea water as it warms up” (Global Climate Change: Key Indicators, 2014). All these indicators data need to be studied as
These long term variations in sea level can be caused by major glacial episodes, changes in the hydrological cycle, vertical land motion or even changes in the ocean and coastal circulation. These reasons can be put into two categories which are known as eustatic and isostatic change. Over the years the global sea level has overall significantly increased from 16BC which was when it was the world’s lowest sea level, however, it has fluctuated throughout the past thousand years. Eustatic change is when there is a rise or fall in sea level changes relative to the land, due to an alteration in the volume of water in the oceans or, alternatively, a change in the shape of a drainage basin and hence a change in the amount of water the sea can hold. Throughout and after an ice age, eustatic change takes place.
All the living and non-living things living within a certain area is known as an ecosystem. Primary and secondary succession will both affect the rate at which an area will reach climatic climax. Primary succession is when plants colonise an area for the very first time, such as after the ice age once the ice had melted leaving behind bare rock where the pioneer species of mosses and lichens could begin to grow. This is known as lithosere primary succession, this will eventually lead to a climax community however, this will take a very long time due to the environment being very hostile and there being very little or no soil present. Primary succession isn’t likely to occur in the UK as there isn’t much bare rock left.
The heat transferred by oceans currents and southwesterly winds to the shores and coastal ranges of Norway is the answer for this. Warm waters, heated by insolation in the subtropics, feed the Gulf Stream. North Atlantic Current then warms the UK and northwestern Europe. On its way north, the Gulf Stream transports some 100 million cubic meters of water per second, 5 times greater than the flow of the Amazon. This enormous flow of water brings large amounts of heat, which are available through redistribution by latent heat flux.
An example of this can be found in glaciation. During glaciations the weight of ice pushing on the Earth can depress the crust, causing the land to fall relative to the level of the sea. When the ice goes in warmer periods the land rebounds upwards as Scotland and Northern Britain are today - rising relative to the level of the sea. Eustatic sea level change is a GLOBAL change in sea level, linked directly to the temperature of the Earth. In warmer periods there is less ice and the water is warmer, so expands and sea levels rise.
All the Yes points 1.Temperature from history 2.Sea level 3.Weather 4.Because people are losing lives and our climate is changing 5.Many factors involved. All the No points 1.The scale of the problem 2.The need for oil 3.Polar Bears and other species are threatened with extinction 4.Nature will adapt better than we will 5.Kids will have to eat poo Global Warming is not an issue Yes because... No because... Temperature from history If people were able to look at the temperature data for the past 200 years, that data would show that the temperature levels on the planet have always fluctuated. That same data will show that it is human beings who are causing the problem. Pollution
Salt melts ice, and researchers are studying this to find out why. Because of earlier studies, researchers believe that salt does truly melt ice, and it is not just a myth. If these amounts of salt are placed on ice: no salt, 5 mL, 10 mL, 15 mL, 20 mL, and 25 mL, then the ice cube with 25 mL of salt on it will make the ice melt most. Salt as a deicer is a very curious topic, but there is a science behind it. Science Concepts One of the science concepts is the melting point.
Without ice and snow coverage, the lakes suffer from water loss due to increased evaporation. Stable ice that once prevented shoreline and wetland erosion is disappearing and, with it, parts of our beaches (NOAA, n.d.). Known for its signature perched dunes, Michigan's Sleeping Bear Dunes National Park is one of many Great Lakes
A desert is defined as an arid land that receives less than 250 millimeters of rainfall or snow per year where a glacier is defined as a semi permanent or perennially frozen body of ice consisting largely of re-crystallized snow that moves under the pull of gravity (Murck et al., 2008). Now that we know a glacier is defined as a mostly permanent frozen body of ice, this does not mean glaciers don’t encounter change. Glaciers are in fact constantly changing in several ways. Snow that falls on the glaciers surface cause the glacier to change and glaciers will grow and shrink depending on changes in temperature and precipitation (Murck et al., 2008). Before glaciers can move and change they first have to be developed.
First off, it raises the temperature, and also the excess carbon dioxide that does not go into the atmosphere eventually gets dissolved in the oceans causing them to acidify. Water Changes Changes in water include changes in the water level, temperature, and acidity. In the last hundred years, the sea level has risen about “15 cm (6 inches) due to melting glacier ice and expansion of warmer seawater”, and in the next ninety years, “models predict that sea level may rise as much as 59
