Question regarding cars and global warming. Answer because I don't understand.?

The effect of ozone depletion on global warming is not nearly as significant as is the greenhouse effect.

Ozone depletion is known to allow in more ultraviolet light, and that does have some heating effect. But in this case we are not increasing heating in the scale that greenhouse effect does.

By comparison, we would have far stronger reflective effect if we had some volcanic dust up there.

Your car ozone production will have to be far less than your CO2 production if you were driving in Ontario. Our catalytic converters use up most of the ozone to burn out any unburned hydrocarbons, particulates. Both ozone and unburned hydrocarbons and particulates are very harmful to our respiratory systems, so even if ozone is doing good, it is doing so much harm at low level that we choose to eliminate it.

Ozone in the stratosphere (above the clouds) absorb some of the highest energy ultra-violet radiation. Tropospheric (the part of the atmosphere were weather occurs) ozone near the ground does not. This chemical is harmful plants, animals, and people if the concentration reaches high enough levels. Stratospheric ozone may cool the Earth, but tropospheric may increase warming (see page 4 of http://www.ipcc.ch/pdf/assessment-report/ar4/wg1/a...

Cars do not emit ozone. The chemical is made in the atmosphere through photochemical reactions. Cars emit NO2 and similar compounds that react with oxygen (O2), sunlight in the presence of volatile organic compound (like gasoline fumes) to eventually create O3 (ozone) and NO. This only happens when the sun is most intense The process is reversed when the sun goes down.

This is why if it is going to be hot with little wind they ask you to fuel your cars in the evening. It reduces the amount of VOCs and as a result, ozone in the troposphere.

Tropospheric ozone does not end up in the stratosphere. The ozone in the stratosphere is made there.

No, for two reasons.

First, ozone (like CO2) is a greenhouse gas. Ozone is transparent in the visible range, but absorbs in both ultraviolet and infrared. That means that ozone in the stratosphere actually keeps the stratosphere warm, as well as keeping UV rays out.

Second, stratospheric ozone is different from tropospheric ozone. All stratospheric ozone is formed either from UV light itself, acting on free oxygen, or (less frequently) in lightning from thunderstorms. Essentially NO surface-formed ozone can make it up to the stratosphere, because it's too dense.

There is some relationship between the ozone layer and global warming, these are really two separate issues. The mass media and pop culture often confuses these two issues.

Global warming is related to increasing amounts of greenhouse gases (water vapor, carbon dioxide, methane, nitrous oxide, etc.), and holes in the ozone layer are caused primarily by CFC’s (chlorofluorocarbons).

“Holes” in the ozone are areas where the ozone layer has thinned, or has partially been depleted. CFCs are mainly released at northern latitudes--mostly from Europe, Russia, Japan, and North America. Once in the atmosphere, CFC’s reacts with sunlight and ozone molecules in such a way that the ozone breaks down. Ozone concentrations around the world have decreased, but the thinning has been most dramatic in the sky above the South Pole. A combination of specific weather conditions and CFC chemistry created this hole above Antarctica.

The Montreal Protocol is a wonderful example of an international treaty designed to protect the environment. It went into effect on January 1, 1989. Due to its widespread adoption and implementation, the concentrations of the most significant ozone-depleting molecules have leveled off, or begun to decrease.

This concept of ozone layer depletion was politically controversial in the 1990s but has broadly been accepted by the scientific community. Paul Crutzen, Mario Molina, and F. Sherwood Rowland were awarded the 1995 Nobel Prize in Chemistry for discovering the chemical mechanism that links CFCs to ozone depletion. The Montreal Protocol was negotiated under the auspices of the United Nations and is widely seen as a model for the Kyoto Protocol. The scientific basis of ozone depletion has been disputed by some global warming skeptics and related institutions, including Patrick Michaels, Steven Milloy, and Fred Singer (this is one more reason why these guys should not be taken seriously).

Why not just plant trees and other green growing things that will eat the carbon and release oxygen for people and animals to breath. I know it is a stretch for AGW believers out there but each and every Co2 molecule out there contains two oxygen atoms for every carbon atom. If we pump the Co2 underground or shoot it into space pretty soon we will run out of oxygen atoms and we will all stop breathing.

Remember Co2 equals

Two oxygen atoms and only one carbon atom.

Green growing things eat the carbon as food and release the oxygen for us to breath.

If we sequester Co2 or shoot it into space we are eliminating the very oxygen we need for us to breath and stay alive from the atmosphere.

So do not sequester Co2 in any fashion, plant lots of green growing things so we can continue to breath and stay alive and healthy

Cars release too much CO2 for trees and plants to take in. Trees and Plants take in CO2 and release Oxygen. If there is too much CO2 for them to take in then it has to go somewhere and do something right? Cars release more CO2 then they release trioxygen. The amount of CO2 outweighs the amount of trioxygen being put out.

Global warming isn't real, and more people are starting to get that. I don't know the answer to your question, but cars (and anything else man-made) have a miniscule impact on the natural warming/cooling of the earth.

Global warming is created from OIL REFINERS plus some states do not do a em-mission test on all cars this creates pollution, CT. does TX. does NOT. that's an example ,,,,, .Russia is one of the biggest Country's for POLLUTION its not just hear in the U,S.

global warming isn't real durrr
