The process of warmth circulating and the natural greenhouse effect are well balanced. Every change in the concentration of greenhouse gases leads to the aggravation of greenhouse effect which in turn leads to the aggravation of global warming. Global warming is increasing the melt of ice in the Arctic region. Today scientists do not challenge the destructive force of human activity. Now, they are deeply convinced that the slightest change in the ability of Earth to absorb warmth, including the use of greenhouse gases and aerosols, will change the atmosphere and world oceans temperature and will destroy the steady types of circulation and weather.
Discussion The role of oceans is very important in the life of the Earth. Why? Because oceans already contain 36 trillion tons of carbon and can absorb annually an additional 10 GtC from the ocean surface components. Currently the oceans surface absorb from the atmosphere 2. 5 GtC, it is nearly 40% of all anthropogenic emissions. In the Arctic, satellite measurements of sea ice show summer melting periods have increased at the rate of 5. 3 days per decade since 1979, lengthening the lean time for polar bears, which need solid ice to hunt ringed seals.
A recent New York limes report also notes that Alaska is about five degrees warmer than it was 30 years ago, causing glaciers to retreat and permafrost to melt, ultimately affecting coastal wetlands like those in Mississippi and Louisiana, where scientists fear a corresponding rise in sea level would put submerged grass beds out of reach of redhead ducks and other species that depend on them. The greenhouse gases could warm the planet and have a huge effect on life, as it known on earth. Sea levels could rise due to melting glaciers and ice. This could cause severe flooding and erosion in coastal regions.
Harsh weather conditions have already become more fierce and frequent and could get much worse. Many plant and animal species may become extinct because they are unable to adjust at the rate the climate is changing. (Finley) More than 520 natural disasters wreaked havoc worldwide during the first ten months of 2004, and the majority of these catastrophes were weather-related, according to the United Nations Environment Program. During the next ten years, a trend in increased rainfall, caused by global warming, can be largely to blame. Environmental experts say agriculture, health, water supplies, and wildlife are increasingly suffering under the growing global warming crisis. Industrialized nations should take action to help the poorer parts of the world adapt to the increasingly unstable and extreme environments that are likely to come.
The recent back-to-back major hurricane season, which is not over yet, is nothing but a prelude to the future. According to scientists, the effect of global warming is behind the increase of killer hurricanes. The periodicity of hurricanes in the next hundred years is going to increase by 60-70% according to recent studies.
