Global Warming


Global Warming
Ecclesiastes 1: 4” One generation passeth away, and another generation cometh: but the earth abideth for ever.”
The hotter the temperature the more the climate changes. Just in the last year the U.S has seen the hottest year in history and record breaking droughts over 60% of the country.  The sea level has been accelerating rapidly by 7 inches of the past century.
In the atmosphere carbon is attached to some oxygen in gas called carbon dioxide is a green house gas and traps heat in the atmosphere. Without greenhouse gases earth would be pretty much frozen. Since all of the pollution that has been going on there is about 30% more carbon dioxide in the air than there was over 150 years ago.
The nitrogen cycle carries out a process known as nitrous oxide also known as laughing gas. This is also a green house gas which contributes to global warming.
The ozone layer is a belt of natural occurring ozone gas sits 9.3 to 18.6 miles above earth and in a sense is a shield from ultra violet radiation emitted by the sun. For a little while now there have been large amounts of concerns that the ozone level is deteriorating, thanks to the release of pollution contaminating not only the ozone layer but the rest of the earth as well. According to the U.S Environmental protection Agency “One atom of chlorine can destroy more than a hundred thousand ozone molecules”.  (National Geographic)
Not all global warming is man made  the ocean contains more carbon dioxide but when it is warm it releases carbon dioxide naturally induced.
The ozone hole formation differ from that of mid-latitude thinning. Most important process in both catalytic destruction of ozone by atom halogen. The main source of these compounds are sent into the stratosphere after being emitted at the surface. Both of this type of ozone depletory were observed to increase an amount of halo-carbon increased. There have many thoughts of biological consequences such as increase in skin cancer, damage to plants, and reduction of plankton populations in the oceans photic zone may have been resulted from a large zone may have been resulted from a large increase of UV exposure due to ozone depletion.  
With global warming as with any other topic, it is crucial to understand what the facts are.
