Why is there virtually no depletion of the Ozone layer except in Antarctica?
Records of increasing UV-B arriving at Earth's surface exist for regions north and south of the equator, dating back to the 1700s, in some cases. This indicates that ozone depletion is a natural and localized phenomenon. We agree that the Arctic also has a thin layer (neither is a hole with no ozone) during it's winter. This thinning layer is no where as large as that of the southern hemisphere due to the angle of our planet verses distance to the sun in orbit. We also agree that at best, man is a minor player in this issue. The politics has gone so far beyond the science, it is laughable. 1859 saw the largest disruption, by solar flares, yet many claim solar activity and Maunder Minimums have nothing to do with this issue. Thus proving how little we actually understand about our own atmosphere. We see virtually no depletion the equatorial regions of our ozone, despite this being the most populated areas for man and his pollution. This is solely because the sun and it's energy are the principle causes of the thickness of the ozone layer.
What can we do to help repair the hole in the ozone layer?
Some believe that they have found that the ozone layer is being damaged, reported it. Politicians have then pushed and been a pain-in-the-tush to make sure some candidate chemicals were banned while scientists continue to prove their theory. They helped kill the Concorde, which was shown to damage the ozone layer. (Not true! The Concord flight was discontinued due to age of the aircraft and a major incident killing everyone on board due to their age.) Most of them are implementing personal choices that reduce their contributions to ozone layer depletion. Most Science experts agree that the Ozone layer's thinning is only at the poles and only during their winter months. They realize that the vast bulk, if not all, of the thinning is natural and due to a lack of sunlight. The banning of chemicals that are heavier then air to help a portion of our atmosphere that is very high is actually a very hard sell. Logic and honesty can not be used. Items heavier then air seldom fly to levels of 50,000 feet. They also realize that the greatest thinning (thus the largest hole) happened in the 1830's which was well before cfc's were in use. We know that this "hole" is caused by a lack of sunlight in the affected areas, not cfc's.
What did these countries agree to do?
Reduce greenhouse gas emissions
What did the US and the Soviet Union agree to start?
Reduce nuclear weapons
What did the soviet union and US agree to do in start?
Reduce nuclear weapons
Why did the United states and the Soviet Union agree to do in start?
They agreed to gradually reduce the amount of nuclear weapons held by each country - the did not, however, agree to reduce the number of warheads carried by each missile !
What did the United states and Soviet Union agree to do in START?
Reduce Nuclear Weapons, people! I HAVE FURY!
What are people doing to control the ozone?
The 1987 Montreal Protocol got all countries to agree to phase out chlorofluorocarbons (CFCs) which were then used in aerosol sprays and refrigeration. Chlorine from CFCs destroyed ozone in the ozone layer which led to the weakening of the layer. Now in 2012 scientists believe that ozone seems to be no longer being destroyed, but it will take up to 2060 before the ozone layer has repaired itself.
Can you reduce monthly mortgage by reducing percentage going to principal?
Yes, but your lender has to agree to it.
Why the president Truman agree to use the atomic bomb?
To reduce US casualties and to shorten the war.
Will the mass of a matter decrease when atoms are taken out?
the mass cannot decrease as we cannot take atoms out of matter .if i agree that scientists remove still i don't agree that matter will reduce .
Why did many governments around the world agree to ban the production and the use of cfc's in the mid 1900s?
The Montreal Protocol on Substances That Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) is an international treatydesigned to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. The treaty was opened for signature on September 16, 1987, and entered into force on January 1, 1989, followed by a first meeting in Helsinki, May 1989. Since then, it has undergone seven revisions, in 1990 (London), 1991 (Nairobi), 1992 (Copenhagen), 1993 (Bangkok), 1995 (Vienna), 1997 (Montreal), and 1999 (Beijing). It is believed that if the international agreement is adhered to, the ozone layer is expected to recover by 2050 . Due to its widespread adoption and implementation it has been hailed as an example of exceptional international cooperation with Kofi Annan quoted as saying that "perhaps the single most successful international agreement to date has been the Montreal Protocol". It has been ratified by 196 states
