Global Warming – is Planet Earth in Peril?
by Global warming has been described as the greatest threat facing humanity for one thing the physical process that underlie global climate systems are complex and not fully understood.
Signs of Trouble?
“Veu Lesa, a 73 year old villager in Tuvalu, does not need scientific reports to tell him the sea is rising. The beaches of is childhood are vanishing. The crops that used to feed his family have been poisoned by salt water. In April 2007, he had to leave his home where in a spring tide flooded it, and the waves showered it with rocks and debris.
What Some Predict?
Many believe that human activities are major cause of global warming which may have catastrophic consequences for the climate and environment. For example large-scale melting of land –based ice and the expansion of the oceans as water warms could cause sea levels to rise drastically.
At the same time, rising temperatures could intensify storms, floods, and droughts. In the Himalayas, disappearing glaciers form areas that feed seven river system – could cause shortages of fresh water for 40% percent of the world’s population.
Rising temperatures may also fasten the spread of disease by enabling mosquitoes, ticks, and other disease – carrying organism, including fungi, to spread farther afield.
Temperature Rise – Is it Real?
According to recent report of the UN – sponsored Intergovernmental Panel on Climate Change (IPCC) global warming is unequivocal or a fact and very likely mankind is largely blame.
The Greenhouse Effect – Vital for life
A reason given such changes is an intensification of the greenhouse effect, natural phenomena vital for life on earth. When energy from the sun reaches the earth, about 70% percent is absorbed, heating air land and sea. Eventually, the absorbed heat is released back into space as infrared radiation thus preventing the earth from overheating. But when pollutants change the composition of the atmosphere, less heat escapes. This case earth’s temperatures to rise.
Is Nuclear Power a Solution?
In France, one of the world most nuclear – reliant countries, up to 670 billion cubic foot of water is required annually to cool reactors. In the heat wave of 2003, the hot water normally expelled from France’s reactors threatened to raise the temperature of rivers to environmentally damaging levels.
Earth’s Future – In Whose Hands?
Will such maturity rise to the fore? Working against it are many factors: apathy, agreed, ignorance, vested interest, the scramble wealth developing lands, and the business-as-usual consuming lifestyle of millions who want to maintain a high-energy-consuming lifestyle.
Yes, our planet may appear to be in peril, but it’s continued existence as a home for mankind is not in doubt. Rather, peril waits those who continue to show disrespect for God’s creation.Above, all these things, only God knows how we can cope this problem.
