Article -Chaotic Climate
Author -Wallace S. Broecker
Magazine -Scientific American
The topic that i am issuing is all about the climate. Every day and in everyway we learn and experience something about our atmosphere. From rain to snow (which some of us have yet to experience) the weather is everywhere. From the magazine, Scientific American, comes an article on Climate changes over the next two decades.
A touching issue on the aspect of our delicate balance of nature. The author of this editorial Chaotic Climate is Wallace S. Broecker. A man who has acheived his PhD. and also did a 40 year study on and about North Atlantic Currents. He has analyzed various sources leading from Weather Balloons to Ice Cores in the Greenland Icecap (where weather from 100,000years ago can be located). Now Ice Cores can also help alot in the study of prediction.
This concept proposed by Broecker of the delicate balance of air streams to ocean currents is known as the Global Conveyor. The global conveyor belt (known technically as the thermohaline circulation) operates when the heat from the sun on the Atlantic Ocean is conveyed northward by currents, heating the north Atlantic. The ocean loses its heat in the very northern reaches and can become more saline due to ice production. The cold water sinks to the bottom (forming North Atlantic Deep Water) and circulates to complete the conveyor belt.
It is believed that the pattern the earth is in at the moment will create drastic changes in the weather. For example, if the earth were to undergo a 4 to 5degree celcius change the conveyor belt may be forced to shutdown resulting in irregular weather effects across the globe.
If this delicate balance were to become disrupted, over time our great Conveyor belts may shut down resulting irrational behavior in the earth's nature.Forests may become tundras, and the resulting after effect may lead to an Ice Age in the future. In a recent movie known as "The Day After Tomorrow", the events that Wallace S. Broeker explains are shown in dramatization.
Unknown to many Broecker has been very active in the Environmental Policy Debate. Everyday that the weather is observed his predictions seem to become more visible. This one atricle i read was one of the 400 he's published and just a piece of his literary works like "Chemical Equilibira in the Earth" and "Tracers in the Sea".
The scientist Broecker was able to aquire his vast amount of of data by using Radiocarbon dating to see the history of the ocean and its many climatic changes. The concept as said earlier before used to catagorize the large and vast balance the earth has pertaining to ocean, air, and climate. The Global conveyor is a balance. The way we live is due to the unbalancing of this nature.
From El Nino to the accumulative amount of Hurricanes in the past few months the earth is becoming more fragile each and every day. We continue to pollute and create amazing amounts of waste in ways we cannot dispense of. There are many ways to save and create better efficient energy.
It is known that there is now Hydro Generators that use the current as a means to generate electricity. Also diesel engines give off less gas emissions and embetter the atmosphere. More and more of the Ozone may be depleting due to pollution and Car exaust emissions despite the steps we can take to revolutionize the industry.
We say that we are pressing to make the earth a better place in which our future generations may enjoy cleaner air and a better atmosphere. I'm hoping the future president, Kerry or Bush, will push for a change to save energy and create better lives for everyone and thier generations to come.
