Assuming that Global Climate Change is happening?

Question

Clarify this for me...

CO2 *adds* to the ozone layer and thus more heat is bounced back to earth? Or is the ozone layer depleting?

I have read several articles and it was not as clear as I assumed that it would be. Resources please?

BTW, please resist pasting large irrelevant answers on here. The process that this theory is based on is what I am interested in.

Thanks

Answer 1

Ozone and Carbon Dioxide are two separate gasses, and form different parts of the atmosphere. Ozone depletion and Carbon increases are two separate issues. The ozone acts as a shield against ultraviolet radiation, and its thinning leads to increased cancer rates and other problems. Carbon Dioxide, as well as other "green house gasses" insulate the planet and retain heat by reflecting infrared radiation back to the earth.

Answer 2

So far, no one has gotten this right, though joecool came close.

The ozone layer and its depletion and global warming are not connected.  There is a naturally occurring layer of ozone in the upper atmosphere, this absorbs ultraviolet radiation shielding the planet.  There is a theory that emissions of certain man made gases such as freon result in depletion of this natural ozone layer.  Most of these gases are no longer produced so this is really a dead issue now.

Global climate change (aka global warming) is attributed by some to the increase in CO2 from human consumption of various fossil fuels.  CO2 absorbs (not reflects) infrared radiation (i.e. heat) causing the atmosphere to heat up.  CO2 is not the only gas that does this, others include water, sulfur oxides, nitrogen oxides and some of the chemicals that have been used to replace freon (this is the only real link between ozone layer depletion and global warming, and is a perfect example of the law of unintended consequences).  The atmosphere is not getting thicker, just hypothetically, more heat absorbent.

Answer 3

no. co2 adds to the greenhouse effect and thus more heat is bounced back to earth.

ozone is also a minor greenhouse gas so it would also add to the greenhouse effect. a warmer earth (as a result of global warming) would also lead to more low level (tropospheric) ozone pollution. a large component of smog which causes thousands of deaths each year.

Answer 4

Let me start off by saying we (my family and I) live 100% off of the grid and are completely self-sufficient with a 0% Carbon footprint. I believe this is the first step anyone can make “help the environment”. Once you convert your own life style to a greener more eco friendly route, you can start helping others.

We definitely didn't start global warming, but we definitely do contribute to it now.

Natural gas (or Methane along with other thanes) for example, is completely a natural contributer to global warming and is derived pretty much the same way as oil. ie. Matter (animal, plant etc) decomposes over time resulting in a anaerobic (hope I spelled that right) decay of non-fossil organic material / gas (natural gas or methane).

One problem with global warming is that the concept is so vague in the minds of the people. The critical interpretation is basically how it’s explained in school and the news. However most of the public see global warming connected with the ozone and pollutants which cause harmful greenhouse gasses, etc. therefore investigating and fighting for things like alternative energy (ie. Solar, wind, hydrogen, ethanol, biodiesel, etc)

Greenhouse gases are real and do contribute to global warming. Think of the different gas layers like ozone (o3) that circumference the globe as the clear plastic on a greenhouse. Longer rays of light from the Sun go in and reflect off different thermal masses bouncing back and creating shorter lengths of energy that cannot exist the plastic barrier. These beams then just continue to bounce around inside the green house until they’re finally absorbed completely (some do escape but very few), thereby warming the greenhouse greatly even in cold temperatures.

Basically there are 2 ways that this reaction (or lack of) affects the planet. Global warming and global cooling.

1. as we add to the gases in the stratosphere, where the ozone layer is (Carbon dioxide, carbon monoxide, etc), we add to the plastic of the greenhouse, trapping more short wave length energy and heating the earth more.

2. as we deplete the ozone (with chlorofluorocarbons or CFCs), we allow more long wave length energy, which bounces back out to space without heating any thermal masses on earth, thereby cooling the planet.

It’s pretty easy to see the results..

Melting ice sheets & glaciers

Floods & droughts

Great hurricanes & cyclones

Seasonal extremes

Seasonal phenomena’s

Species extinction

New & resurgent diseases

There are many ways to stop both global warming and cooling from accruing or at least slow them down until we can discover a way to reverse it, but Stop burning fossil fuels is the biggest.

I currently own 2 converted h2 vehicles which run on 100% hydrogen and 1 EV (electric vehicle), not to mention our home is completely off the grid, using alternative energy (solar, wind, etc)

Answer 5

Our planet is surrounded by a blanket of gases which keeps the earth warm and makes it able to sustain life. This is getting thicker as increasing amounts of greenhouse gases are released by burning fossil fuels for energy and transport, trapping in heat. As a result, our climate is starting to change.

The scientific consensus is that there will be a gradual increase in global temperatures by between 1.4 and 5.8 degrees by the end of the century. This will have serious implications for ecosystems, growing seasons, animals and their habitats. There may also be more intense and frequent extreme weather events.

Answer 6

Forget ozone.  It has some minor impact on global warming but it's small.

CO2 passes visible light easily, but reflects some infrared light (heat).

So sunlight shines right through it, strikes the Earth and becomes heat.  Then CO2 blocks some of that heat from leaving, and the Earth warms up.
