Global Warming Solutions

The Global Warming will have a huge impact on the environment and therefore in our lives. Should greenhouse gases continue to accumulate in the atmosphere at even a moderate pace, average temperatures by the end of the century could match those last seen 125,000 years ago, in the previous warm spell between ice ages.

Over the past 400,000 years, average global temperatures have been as high as six degrees above and as low as 17 degrees below today’s average temperatures. These changes had many different causes, including volcanic eruptions, oscillations in the Earth’s orbit around the sun and changes in greenhouse gas concentrations.

Scientists say that the earth’s average temperature could rise by between 2.5 and 10 degrees Fahrenheit by 2100. This would put global average temperatures at the highest levels in thousands of years. The temperature today is changing at a rate faster than ever, and it is caused by man-made mechanisms, not the natural ones that led to previous climate oscillations.

Today, climate change is being driven by the addition of carbon dioxide and other greenhouse gases to the earth's atmosphere at rates faster than the planet's normal mechanisms can adjust to.
The major consequences will be the melting of big parts of the polar ice on the north and south pole . The effects of global warming on Arctic and Antarctic ice sheets, especially Greenland and Alaska, will be devastating.

The process of disintegration has already started, and will soon be irreversible. This would raise sea levels by more than 20 meters. So Through the melting of polar ice, there becomes more water in the seas and oceans and the sea level while rise and less heat is reflected out to space.

Through the rising of the sea level big parts of land will be flooded and there becomes less land to live on and to grow food on. Wild fire will be more frequent and larger, each time releasing huge quantities of carbon dioxide into the atmosphere and also less trees means less carbon dioxide absorbed. Methane clathrates held in the mud under the sea begin to burp, melting permafrost releases vast quantities of methane, drought kills the Amazon forest and its carbon sink is released (not only it will stop absorbing carbon dioxide it could actually release more carbon dioxide),extinction of many animal and plant species, among several other consequences.

So supplies of food and water will be greatly diminished from flooding, sea level rise, drought and chaotic weather and lets not forget that there are vast stores of CO2 and methane held in forests, in the oceans and in the soil. Before 2 degrees is reached these greenhouse gases will start to seep into the atmosphere. This will increase temperatures further, triggering the emission of more carbon dioxide and methane - and a dangerous and unstoppable feedback loop will have started. Global warming is one of the most serious challenges facing us today. To protect the health and economic well-being of current and future generations, we must reduce our emissions of heat-trapping gases by using practical solutions already at our disposal, know –how and the development of new technology.
