- Global temperature should increase by between 1.4 and 5.8°C (2.5 to 10°F).
- The Northern Hemisphere cover should decrease, but the Antarctic ice sheet should increase.
- The sea level should rise by between 9 and 88 cm (3.5" to 35").
-
Other changes should occur, including an increase in some extreme weather events.
After 2100, human induced global warming effects are projected to persist for many centuries.
The sea level should continue rising for thousands of years after the climate has been stabilized.
Evidence Of Global Warming – Man-Made
The majority of people in the world accept global warming is happening most of those believe that humans are primarily responsible for this; there is clear evidence of changes in the composition of the greenhouse gases in the lower atmosphere. Ice core samples show that both carbon dioxide and methane levels are higher than at any time in the past 160,000 years.
This graph shows that as the years go by the temperature of the world starts to rises and shows that global warming is taking place
These picture shows that global warming is taking place because you can see the difference of the pictures, in the first picture you see that there is
Snow on the mountain and in the second picture you see that the snow is nearly gone.
Evidence Of Global Warming – Natural and My Own Opinion
Approximately 2.7 million years ago, the ice-age wiped out many different species, this sudden change of climate was due to a natural cycle and I believe the same thing is happening today. I believe volcanoes contribute to the greenhouse gases because they release enormous amounts of gases in a small period of time, animal waste, also adds to the greenhouse gases, the west German chemists suggest that the world's cattle emit into the atmosphere approaching 100 million tonnes of methane each year, enough to warm up the planet. As this graph suggests, the world is producing more methane than ever before, this rise could explain the rise in temperature over the last few years and negate belief that CO2 emissions is the main cause for global warming.
This graph also backs up the point that Carbon dioxide Is one of the culprits for global warming, as you can see in the graph CO2 is closely linked within the temperature.
And here is the Methane graph, this also shows that this is also a contribution towards global warming, as you may see within the graph.
My opinion on the causes of global warming is that it is a natural cause
Yes, climate fluctuation happens naturally but natural changes occur over thousands of years. The recent sharp rise in global temperature has occurred during just the past century. Nothing like that has ever happened before, and the rise corresponds precisely with the rapid growth of industry and pollution. Those who deny the reality of global warming are not looking at the facts.
Another way i look at this subject is that global warming is due to the fact that the earth is closer to the sun, this proves that global warming is not man made it is natural. Venus is a little less than 30% closer to the sun, and its clouds reflect most sunlight back into space, yet the atmosphere about 96% CO2 and about 90 times as dense as Earth’s, traps enough heat to make the surface hotter than the planet Mercury, just about hot enough to melt lead.
Altering fuel economy on vehicles will not save the Earth. This is just another way of the government to raise money, therefore in my opinion I don’t think the world could be saved. Even if the government tries hard enough it simply won’t work.
What We Should Do To Stop Global Warming
Individuals
Individuals should recycle more, and contribute to stopping global warming by driving less, and using public transport more often. They can also save 250lbs of carbon each year by keeping their tyres inflated at the correct level, but the most efficient way of saving carbon is by buying a hybrid car, doing so can save 16,000lbs of carbon yearly.
Government
Government regulation: Government can require desired behaviors (e.g., force auto companies to build more efficient cars). An advantage of regulation is that it specifies the desired outcomes and can force action. However, regulation can be inflexible and discourage innovation.
Prices and markets: Higher prices for fossil fuels encourage people to save energy by promoting energy efficient devices and behavior (e.g., expensive gas prompts companies to make and people to buy more fuel efficient cars). Government subsidies and taxes can also influence behavior. An advantage of using prices is that they present a constant incentive to innovate. However, using prices can have undesirable side effects, such as imposing a relatively larger burden on the poor.
Information and education: People often do not know how to improve efficiency or reduce emissions. Government can provide them with the information they need to make better choices.
Research and development: Government and industry can support research to demonstrate and improve existing technology, and to develop new technologies that use less energy or emit no carbon dioxide (e.g., refrigerators that use less electricity, cheap practical solar water heaters, and inexpensive solar/hydrogen technology).
