It would change our climate, but it would not bring us close to the level of uninhabitable Venus. A doubling in CO2 levels would make agriculture much more difficult due to shifts in climate that occur as a result of increasing temperature. CO2 can indeed cause a significant degree of warming if it is suddenly released into the atmosphere, as we have been doing for the past 150 years. Aside from that, increasing temperature can also cause the rising of sea level as the glaciers are going to melt at a faster rate like never before. Next, is the change in environmental health.
Yes, climate change will result in the extinction of species. * 7Global warming will melt down some of the glacier, which will destroy the habitat of species that are living near the South and North Pole. Eg. Polar bear; Penguin * 2The melt down of ice will raise the water level; species that used to live in low lands will now have nowhere to live. * 1In western North America, global warming results in reduction of availability of water for ecosystem.
The Extinction of the Polar Bear What Greenhouse gases are, how they work, and why they are threatening the very existence of the polar bear. “If a warming world melts nearly all sea ice during summers, as computer models predict will happen by the end of the century, scientists warn that the polar bear is unlikely to survive as a species.” Jordan Sherry 05-30-06 The Problem Carbon dioxide is what’s know as a “greenhouse gas” meaning it is able to keep the Earth warm by trapping some of the heat it produces within the Earth’s atmosphere. But if too much of the gas is trapped in the atmosphere it can get too hot, and according to scientists that is what is happening now. Starting during Industrial Revolution to concentration of carbon dioxide has increased by nearly 35 percent, which is more than the Earth has experienced in more than 650,000 years and more than the natural variability would allow. This in turn has cause the average temperature over the past century to raise about 1 degree, and another 4 degree increase is expected during the 21st century.
Furthermore, mercury spreads and destroys plants and animals in the area. All of the above help to cause the greenhouse effect, affecting global warming massively. If this continues the oxygen throughout the world will decrease. A staggering 40% of the world’s oxygen supply comes from the rainforest. Statistics state, and I quote; “at this rate the rainforest only has 28 years left “.
Owing to the development of industry and the use of fossil fuels, the amount of carbon dioxide in the earth’s atmosphere has produced and the average global temperature seems to have risen. What’s more, deforestation can affect climate changes. The growing of trees and plants can absorb carbon dioxide from the atmosphere because of photosynthesis, however, deforestation lead to carbon dioxide emissions. Both of these can lead to global warming of the atmosphere. The report (UNEPWMO, 2004, P10) also pointed out, the burning of fossil fuels and deforestation are altering the composition of the atmosphere and contributing to climate change.
EAP VI/A R/W YUCHENG WAN 11/27/12 Is Global Warming Manmade? Abstract Global warming is caused by numerous activities such as driving, taking airplanes, generating electricity, displaying fireworks, using air conditioning, developing industry and logging because those activities emit so much carbon dioxide that global temperatures rise up. Trees store CO2 in the forest system, so if forests are damaged, much CO2 will be released, which will increase the global temperatures. As this paper illustrates, natural climate cycles have already changed from warm to cool, so global warming is not because of natural factors. The solutions for global warming may include improving the efficiency of energy, protecting forests, producing more energy from renewable sources, generating electricity by wind, traveling in more fuel-efficiently vehicles, riding bicycles and using more efficient electrical appliances.
Since we have the attention of everyone, now is the best time to take action against global warming. Due to the increasing temperatures every year our public health and our agriculture/food supply is at high risk for new and worse diseases due to global warming; we need to change our climate control policies to protect ourselves. Gases are being trapped inside of earth’s atmosphere like a soda can, and are gradually increasing Earth’s temperatures that ice will start melting and there will be flooding due to rising sea levels; plants and animals will start becoming endangered (as cited in Cooper, 2001). We have already seen coastal flooding in parts of Central America and Bermuda’s forests are now endangered due to flooding (as cited in Clemmitt, 2006). Global warming has been an issue since factories were introduced to this world; gases and toxins are being highly exposed into our atmosphere causing a tremendous reaction to the balance of nature.
Today, as in the past, oceans are being treated as giant disposal areas for all types of refuse (plastics, tins, bottles etc.) with the belief that the enormous size of the oceans would be enough to dilute and break-down any materials we put into them. Most of the waste we produce on land eventually, in one way or another, reaches our oceans, either through deliberate dumping or from run-off through drains and rivers. But, sadly, now we have to reap the ramifications of our choices. With an average of 6.3 million kilograms of trash being pumped into our oceans every year, it won't be very long until they reach breaking point.
I strongly agree that people should give up their cars to save the earth. First of, according to Environmental Protection of United Kingdom, statistic proved that cars account for 22% emission of carbon dioxide which is the major contributor to climate change. World’s climate has been fluctuating throughout this decade and it arise the concern of many. Ices in North Pole are partially melted due to the drastic increase in temperature. This does not only affect the habitats living in North Pole but causing sea level to rise on top of this.
They lose their habitat and forced to move to new location; besides, many cannot survive the deforestation that destroys their homes. It is undeniable that deforestation itself has extreme effect on Global warming and hurts the air. Global warming means that air and ocean temperature is increasing. Greenhouse gases exist primarily because of human activity. Unfortunately, humans are the most polluting species on the planet.
