The intermediary outside occupying reports, earthly ozonosphere is empty although already restoring gradually, but the environmental impact that this does not mean it has ended. A new checkup studies labor additional ultraviolet radiation is right environmental influence, make climate belt and marine temperature produce change for example, and the frangibility that brings about certain species.
Change like present climate same, ozonosphere is empty it is 20 centuries 80 time and the great environment crisis that 90 time appear. This covering layer is located in the altitude of earthly aerosphere, ruinous ultraviolet radiation is absorbed by ozone in headroom, in hold the world appropriate living respect is producing crucial effect. In 80 time metaphase, the scientist is in antarctic in the sky discovered an ozonosphere is empty.
Culprit but restrospect to contains chloric fluorine hydrocarbon (CFCs) chemical, these chemical use as normally refrigeration agent and production gas collosol. Should be when atmosphere is medium, discover these chemical material rise to react and begin deliquescent ozone to sunshine. Realize this one risk, each country government was signed 1987 " Montreal protocol " , fell into disuse to contain the use of hydrogenous fluorine hydrocarbon stage by stage.
Come more than 30 years, this ozonosphere is empty restoring gradually it seems that. Restore a process to still make progress however slow, and this ozonosphere is empty still produce a few effects to the environment. Now, u.N. environment affected the researcher that evaluates a group to undertake one examines research, so that understand its better,specific meeting produces what effect.
The biggest change is antarctic billows is moved it seems that (Antarctic Oscillation) . This is middle latitude of the Southern Hemisphere and tall latitude of the measure of a kind of whole world that air mass changes between belt of activity of state of two big compression ring " seesaw " structure, this wind belt is mixed north as the elapse naturally of time normally Xiang Na is mobile. But this examines research discovery, be located in Antarctica the ozonosphere of upper part is empty had made antarctic billows moves farther Xiang Na to move, before comparing its about the more of millenarian shift.
The variation that antarctic billows uses takes climate Xiang Na to drive, changed rainfall pattern, offshore temperature and ocean current. This changed the climate of whole hemisphere, to Australia, New Zealand, Antarctica, South America, Africa He Nabing silvers coin influential.
Deep-sea differs to the part becomes more warm or become cold, this produced an effect to the ecosystem of these areas. Warm seawater destroyed Australian islands the algal bed all round the city mixes Dasimaniya the cay with coastal Brazil. But become cold to bring profit for a few area actually, bring about appear more fish and phosphorous shrimp, these are penguin, seal is mixed avian the food that waits for place to need.
"What what we see is, ozonic change had changed the temperature of the Southern Hemisphere and precipitation pattern, this changed the alga in ocean, changed fish, sea-ox and the section that seal lives, so we " a lot of change in seeing food chain, " the say of collective author Kevin Rose of this research.
As a result of the combined influence of climate and ozonosphere hole, other live thing is sufferring more hardship. The carbon dioxide of higher level in atmosphere makes ocean becomes more acidity, make conch thinner thereby, and accept arrival more easily harm from the radiant of additional ultraviolet radiation with empty ozonosphere.
Change in climate and ozonosphere is empty between also exist it seems that " feedback loop " . "Greenhouse gas is discharged can capture in low layer air more quantity of heat, bring about high-level air to drop in temperature thereby, " Rose expresses. "Because ozone is extinct below colder temperature, colder high-level air is making of ozonosphere restore speed slow down. Colder high-level air is making of ozonosphere restore speed slow down..
