can global warmin be stopped?

Question

it s my q so wat am i to say about it plz help its 4 a n english paper

Answer 1

Global warming is at the fore front because politicians found how to use a new platform to get re-elected. The world leaders use it because they found ways to make money at it. This is a made up problem just like Global Cooling in the 1970's. Wake up people. I agree we need to be more efficient with our resources, and we should fine and jail companies who are dumping into our rivers maliciously. I want to stop the raiforest destruction, but to say that global warming is a serious man made issue and we need to destroy the American economy and bow down to the rest of the world certainly does not float my boat. Follow the money on this one and you will see that it is all for political gain and grant money for those scientists who profit off of the government if global warming stays at the front of the issues. Look deep into the Keoto (sp?) Treaty, first of all they took jets to a non-central resort location. Not very environmentally concious. THen in the parameters of the treaty they have a clause that makes it so you can buy or sell polution credits. This is all about shifting wealth and breaking down the United States. This is painfully obvious, just look at peoples agenda. The earth's mean temperature has risen .6 degrees C in the past 125 years. Greenland's icecaps have gotten colder in the past 10 years. The Scientists who do not gain anything on their posisition will tell you that the earth has a natural progression and this is what we are seeing. The UN report is made up of POLITICIANS not a good spread of scientists. THere are as many or more scientists who believe that man in NOT the reason and it is over hyped, but their voice is not heard in the LIberal Mainstream Media. This issue is 99% political, and an attempt to make the USA a socialist nation, and eventually communisim. WAKE UP AMERICA, IT IS TIME TO BE AMERICANS. FOR THE PEOPLE BY THE PEOPLE. STOP THE LIES

Answer 2

No not by humans. 1000 years ago Vikings farmed in Greenland a places that are far too cold right now. 10,000 years ago Chicago was buried under a layer of ice one mile thick. What was done to end the last ice age, nothing. What did the Vikings do to end the global warming that allowed them to farm in Greenland. Not much of anything I would guess.

There are many variables besides the levels of CO2 and water vapor in the atomsphere that determine the average temperature of the earth's surface. One is the intensity of solar radiation from the sun. Right now the polar ice caps on mars are receding. How do greenhouse gas levels on the earth cause "Mars warming". They don't.

Lets just hope global warming continues. Because when it stops we could be in for global cooling. I think we can live with a foot or two higher sea level easier than we can handle a layer of ice one mile thick over Chicago.

Answer 3

No. Global warming is part of a natural cycle that involves golbal chilling and warming.

Did you know there was a WINE GRAPE growing in England until about the year 1300? What happened to it? The Little Ice Age happened and wiped out the wine grapes.

The climate in England is still NOT WARM ENOUGH for the wine grapes to grow again.

To blame a natural cycle on human activity is really stupid.

Communisum and socialism didn't work to control humans, so now the greenies are using the boogyman of "global warming" as a means to control and stifle the human spirit.

Answer 4

There are some natural events such as volcano eruptions, and processes that encourage global warming but theres an equilibrium that humans have pushed beyond. Without human influence global warming would not be happening (at-least not to this extent). Its too late to stop global warming any time soon, but it can be prolonged and minimized. Global warming will not be helping people to farm in greenland. Global warming will eventually cause an ice age in north america and europe while the earth mean temp continues to rise.

Answer 5

Continental Drift

The process by which the continents drift about the world is called plate tectonics. The movement of the Earth's plates, on which the continents ride, is very slow, being only a few centimetres each year. However, over tens or hundreds of millions of years, both the size and position of land areas can change appreciably.

At times in Earth history, there have been super-continents in which all the continental plates were locked together in one area of the globe. The last of these occurred about 250 million years ago, and is named Pangea. Since that time, the continents have gradually moved apart, the most recent separation occurring between Europe and North America, during the last 60 to 70 million years, to form what is now the North Atlantic Ocean. What is now the Pacific Ocean used once to be the vast expanse of water called the Panthalassa Ocean that surrounded Pangea.

Changes in the distribution of landmasses are believed to explain climate changes that occur over tens or hundreds of millions of years. Of course, we have no direct way of knowing what the Earth's climate was like hundreds of millions of years ago, but we can use geological records of sea floor sediments to reconstruct what the climate may have been like. We can also use computer models to estimate how different arrangements of continents may influence the global climate. Currently, it is believed that the arrangement of continental landmasses significantly affects the ocean currents. Since ocean circulation is involved in the transfer of heat around the Earth, so the wandering of landmasses over tens and hundreds of millions of years may influence climate changes over similar time scales.

Such long-term changes to ocean circulation as a result of continental drift may explain the gradual return to an ice-covered world during the last 40 million years. Prior to that period, there was little ice covering the polar regions. As the supercontinent of Pangea continued to break up, so the continent of Antarctica became isolated at the Earth's southern pole. With ocean all around it, a new circumpolar ocean current formed, and heat from lower latitudes was prevented from reaching the continent. The subsequent expansion of the (white) ice sheet on Antarctica about 35 million years ago increased the amount of sunlight the Earth as a whole reflected, and led to a drop in average global surface temperature. Today, although we live in a period of relative warmth since the end of the last Ice Age 14,000 years ago, the Earth as a whole is still gripped by a much longer period of global frigidity. Temperatures today are still perhaps 10°C cooler on average than they were during the age of the dinosaurs.

As continents break apart, new oceans form between them, through a process known as sea-floor spreading. A major zone of sea-floor spreading is today located along the length on the Atlantic Ocean, and is called the Mid-Atlantic Ridge. At these zones large amounts carbon dioxide are released. During time of enhanced tectonic activity and sea floor spreading, elevated levels of carbon dioxide emissions may increase the strength of the Earth's natural greenhouse effect.

Different rates of sea-floor spreading can also affect the shape of the seafloor. When tectonic activity is greater, the sea floor is pushed up, leaving a smaller volume to hold the water of the oceans. Consequently, sea levels can rise by several hundred metres, covering large areas of the continents with warm shallow seas. Indeed, during the age of the dinosaurs about 100 million years ago, the sea level was much higher than it is today and the climate was much warmer.
