The issue of Climate change is something that has been around us since the beginning but we are not able to understand or really take it serious until the 20th century. The reason for our sudden realization of the negative effects of our actions towards the Environment can be attributed to advancements in Science research. Scientist are now able to determine the level of depletion of the ozone layer; Scientist are also able to calculate the depth of ice sheet even in Antarctica.
The alarm on the consequences of Climate Change being raised by raised by Scientist all over the globe, is based on their studies. Consequently, the phrase 'Climate Change' has become very common in the our discussions and debates in almost every part of our world today. But is talking about it enough?
of course not. What is required is stringent action by world leaders so that the rest of mankind can follow. Climate change is already happening and represents one of the greatest Environmental, Social and Economic threats facing the planet. The warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level. The Earth's average surface temperature has risen by 0.76° C since 1850. Most of the warming that has occurred over the last 50 years is very likely to have been caused by human activities.
In its Fourth Assessment Report (AR4), published in 2007, the Intergovernmental Panel on Climate Change (IPCC) projects that, without further action to reduce greenhouse gas emissions, the global average surface temperature is likely to rise by a further 1.8-4.0°C this century, and by up to 6.4°C in the worst case scenario. Even the lower end of this range would take the temperature increase since pre-industrial times above 2°C - the threshold beyond which irreversible and possibly catastrophic changes become far more likely.
Projected global warming this century is likely to trigger serious consequences for mankind and other life forms, including a rise in sea levels of between 18 and 59 cm which will endanger coastal areas and small islands, and a greater frequency and severity of extreme weather events.
From the above stated fact, we can see that this planet is in 'deep shit' mostly due to man's 'uncaring' behavior and attitude towards his Environment....
