Sentences with phrase «ozone layer so»

Venus, however, has no ozone layer so the feature is absent.

Not exact matches

Why would God make it so complicated??? Seems like God would just say something like «Let there be life» and be done with it, and we wouldn't need an ozone layer, and there wouldn't be astroids or comets that could destroy us.

Nature may kick back at us from time to time — with erosion, pollution, holes in the ozone layer and so on — but we like to think that these are simply impersonal matters of ecological imbalance.

The ozone layer — a high - altitude expanse of oxygen molecules that protects us from the sun's ultraviolet rays — has been on the mend for the past decade or so.

Earth in the days when life was just beginning had no protective ozone layer, so light - dependent, iron - oxidizing bacteria formed iron minerals around themselves to protect them from damaging ultraviolet rays.

Rapid reversals of Earth's magnetic field 550 million years ago destroyed a large part of the ozone layer and let in a flood of ultraviolet radiation, devastating the unusual creatures of the so - called Ediacaran Period and triggering an evolutionary flight from light that led to the Cambrian explosion of animal groups.

The whole country is aware that it is increased ultraviolet light caused by the hole in the ozone layer over Antarctica that makes the sun so vicious.

Some air conditioners still use chemicals that deplete the ozone layer and demand for air - conditioners is expected to rise as a result of global warming, so green buildings could help counter this demand.

On the other hand the depletion of the ozone layer in spring certainly can have a significant effect on ecosystems, although so far the ozone layer has not been thinner in spring than later during the year.

These altitudes are so high that monsoon air then ascends freely into the stratosphere, the stable layer that overlies the lower part of the atmosphere and contains the Earth's protective ozone layer.

So the maximum loss occurrs in the heart of the ozone layer.

On the other hand the depletion of the ozone layer in spring certainly can have a significant effect on ecosystems, although so far the ozone layer has not been thinner in spring than later during the year.

So when we do things that emit GHGs, we also likely emit local pollution that kills, & becomes regional acid rain (destroying lakes, crops & forests), & acidifies the ocean, depletes the ozone layer (some pollutants), and maybe a hundre other harms, in addition to contributing to GW, and to runaway GW.

Imagine that its only radiatively active moiety is CO2 — no ozone, no water to speak of, etc. — so that its temperature is determined by the balance between absorption of incoming infrared by CO2 and emission of infrared out of the layer by CO2.

Again, adding CO2 will increase absorption of incoming infrared (also absorption of ozone - emitted infrared within the layer, but the spectra are different and so that effect is small).

Then, these same «holier than thou» hominids were decrying the looming ice age, and the need to remove hairspray from the planet to secure the ozone layer and eliminate the hole in it that man so glutenously produced.

I guess the question is, if all else was held the same — if we had our fossil fuel industry but had not invented the chlorofluorocarbons and equivalents so hadn't lost so much of the ozone layer for so long — would that change climate sensitivity?

However, as a result of phasing - pout ozone depleting chemicals, HFCs were commercialized by the Montreal Protocol, which is why the Montreal Protocol has a duty to eliminate HFCs so that it will not have saved the ozone layer at the expense of the global climate.

Remember... (from Wiki) Solomon also showed that volcanoes could accelerate the reactions caused by chlorofluorocarbons, and so increase the damage to the ozone layer

Solomon also showed that volcanoes could accelerate the reactions caused by chlorofluorocarbons, and so increase the damage to the ozone layer.

So, the «atmosphere absorbtion» part of solar (67 W / m2 in Kiehl and Trenberth, 1997) is mainly UV absorbtion by the ozone layer 20 - 50k above surface.

But the latest research, published in the journal Atmospheric Chemistry and Physics, finds that the bottom part of the ozone layer at more populated latitudes is not recovering, for reasons so far unidentified.

Even so, it has not been regarded as a threat to the ozone layer, because its typical lifetime in the atmosphere before it is broken down in photochemical reactions is only about five months.

If you knew the slightest thing about the problem with ozone destroying chemicals, of which the chlorinated freons were prime culprits, you would know that they were a problem because they were supremely stable in the lower atmosphere (pure chlorine not so at all), and were able to transport chlorine to the ozone layer (unlike natural chlorine compounds), whereupon UV light broke them down, released the chlorine, starting a chain reaction destroying the ozone.

Now the ozone layer over the Arctic is so thin that for the first time it can be... Continue reading →

My recent Times column argued that the alleged healing of the ozone layer is exaggerated, but so was the impact of the ozone hole over Antarctica:

When scientists discovered a huge and growing hole in the earth's ozone layer, Canadian researchers and bureaucrats were so central to the response that the ensuing global ban in the manufacture of ozone - depleting chemicals would be named the Montreal Protocol.

So in the 1980s, we received their messages through television «programs» (do you understand why they are called programs — to program the minds of the masses) that the Ozone Layer had been damaged / destroyed.

Progress continues on reducing atmospheric amounts of chlorine and bromine so as to allow for the recovery of the ozone layer.

The accumulation of chlorofluorocarbons and other ozone - depleting gases in the atmosphere as a result of human activities have altered this balance so that the ozone layer has become depleted.

Here is how the more active sun would deplete ozone in the higher layers so as to cool them and thereby accelerate the upward energy flux from the stratosphere below which then cools instead of warming when the sun is more active:

The aim of the so - called stratospheric controlled perturbation experiment, or SCoPEx, is to see if sulphate ions would undermine measures to rebuild the ozone layer.

But the ozone layer extends vertically throughout the stratosphere, so using just one measure is like «looking at a flat table,» Douglass said.

CFCs are incredibly stable molecules that must travel high into the stratosphere before breaking down, so though the phasing out of CFCs is working, the impact of the Montreal Protocol won't be noticeable in the ozone layer until about 2025, Kramarova said.

He seemed to be taking a sensibly optimistic attitude towards environmental problems, pointing to our successes in fixing up pollution problems, the ozone layer and so on, rather than focusing on doomsday scenarios.

So the depletion of the ozone layer actually has cooled Earth's climate very slightly.

This week the UN revealed that our actions paid off — the ozone layer is recovering so fast that, across most of the planet, it will be more or less repaired by 2050.

H2O and ozone react differently to solar input so you have yet another solar dependent mechanism for differential warming or cooling of the seperate layers right there.

The protective role of the ozone layer in the upper atmosphere is so vital that scientists believe life on land probably would not have evolved - and could not exist today - without it.

The controversy surrounding environmental policy has, perhaps surprisingly, arisen not so much from the issue of conserving non-renewable commodities such as fossil fuels or industrial metals, but from the increasing scarcity or overuse of renewable natural resources, causing problems such as water and air pollution, or damage to global commons such as the atmosphere or the ozone layer.
