Air Pollution

The Greenhouse Effect works by trapping heat in the Earth's atmosphere. Greenhouse gases like carbon dioxide and methane allow sunlight to enter the atmosphere and warm the Earth's surface. However, they also absorb and trap heat that would otherwise escape back into space, keeping the Earth warmer than it would be without them.

Always best to consult one of the watch sites... Colorado State University is one of the participating members in a program designed to answer your question. see the links below.

Record sized Antarctic ozone hole in 2007, near record in 2008, 2009 season yet-to-occur.

The ozone hole heals when it is not winter at either the north or south pole. But the ozone layer is where UV-B is or is not absorbed by the amount of ozone along a vertical path. Ozone is still allowing more UV-B to arrive at the Earth's surface, so it appears that the ozone layer has not healed itself.

The ozone layer is self-healing. Depletion means that it gets thinner at equilibrium, when contaminants destroy ozone before sunlight gets a chance to. A way to measure the average thickness of the ozone between the Sun and any point on Earth's surface is to measure the amount of UV-B that arrives at a sensor at the surface. The size of the ozone hole is another indicator.

There is no indication that the ozone layer will reach some catastrophic failure point. So far it has shown to be a slow decrease in available ozone to block UV-B, allowing more UV-B to reach Earth's surface.

Ozone is mostly found in the stratosphere because this layer of the atmosphere absorbs and filters out the majority of the Sun's harmful ultraviolet (UV) radiation. Ozone molecules in the stratosphere are formed when oxygen molecules are broken apart by UV radiation and then recombine to form O3 molecules. This helps to protect life on Earth from the harmful effects of excessive UV radiation.

Appliances don't exactly produce carbon dioxide (CO2), but they are responsible for CO2 emissions. Appliances run on electricity, and most electricity is generated by burning fossil fuels (coal, oil and natural gas). This burning emits CO2, a greenhouse gas that is causing global warming.

Cars produce more carbon dioxide than factories on a global scale. Transportation is a major source of greenhouse gas emissions, accounting for a significant portion of total CO2 emissions globally. While factories also emit CO2, the collective contribution of cars is higher due to the sheer number of vehicles on the roads.

The reaction is: C + O2 = CO2

The volume (or the mass) of the released carbon dioxide depends on the concentration of carbon in charcoal; this is very variable.

The pH scale runs from 0 to 14, with 0 being extremely acid and 14 being extremely basic (alkaline). Water with a pH 7 is dead neutral. This is a suitable pH for keeping most tropical fish. If your pH of your water is less than 6.8, it is considered acid water. Fish suitable for acid water include apistogramma dwarf cichlids, angelfish, discus, tetras, gouramis, rasboras, danios, many catfish and barbs. If your pH is more than 7.4 it is considered alkaline. Suitable species for this water include kribensis, some other cichlids, rainbowfish, livebearers (guppies, mollies, platys and swordtails) most barbs and most catfish. Some water is very alkaline, with a pH of over 8. This is generally suitable only for fish that have adapted to survive in these conditions, such as African cichlids - but these are large and demanding, so do plenty of research before you buy a tank for them.

recently it was discovered that the ozone layerwas getting depleted. various man-made compounds like CFC's (carbon compounds having both flourine and chlorine which are very stable and not degraded by any biological process) were found to persist in the atmosphere. once they reached the ozone layer, they would react with the ozone molecules. this resulted in the reduction of the ozone layer and recently they have discovered a hole in the ozone layer above the antartica. it is difficult to imagine the consequences for life on earth if the ozone layer dwindles further, but many people think that it would be better not to take chances. these people advocate working towards stopping all further damage to the ozone layer!

Yes.

But less than the hundreds of thousands of overflights by aircraft that it replaces.

Nature does far more to the ozone layer then a million shuttles a month could do. The main issues with the thinning of the ozone are the lack of sun hitting the layer. That is why the "hole" is a annual event and is self healing. We also know the largest thinning of the ozone layer occurred over 100 years ago during an unusually high solar flare era. The concept that man is a major contributor to the thinning is questionable. The major issues are certainly and unquestionably natural. Man's involvement, if actual, is a recent issue and the natural aspects of this hole can positively be traced back hundreds of years.

Two natural sources of the greenhouse effect are water vapor and carbon dioxide. Water vapor is the most abundant greenhouse gas in the atmosphere, while carbon dioxide is released through natural processes such as respiration and volcanic eruptions.

Yes, animal manure contains methane. Methane is produced during the decomposition of organic matter in manure by anaerobic bacteria. Proper manure management practices can help reduce methane emissions.

Substances that deplete the ozone layer include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, carbon tetrachloride, and methyl chloroform. These substances release chlorine and bromine atoms when they break down in the atmosphere, which then react with ozone molecules and break them apart.

Greenhouse gas pollution refers to the release of gases such as carbon dioxide and methane into the atmosphere, which contribute to the greenhouse effect and global warming. This pollution is primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes. Addressing greenhouse gas pollution is essential to mitigate climate change and its impacts on the environment.

At present food crops are diverted for the production of biodiesel, most commonly corn. Granted, the corn used to produce ethanol is typically field corn rather than sweet corn, but field corn is a common animal stock used for hogs, poultry and beef. The more crops are used to produce fuel, the less are available for human consumption.

One way around this would be to engineer crops that produce sugars in the inedible parts. For example, if we could culture or devise yeast cells that could convert corn stocks instead of corn seed, we could reduce the amount of feed crops diverted for fuel production.

The economic concern comes from the fact that, because carbon emitters can simply vent gas into the atmosphere instead of sequestering it or paying for the consequences, burning coal and oil remains cheaper than producing renewable biofuel.

The layer of the atmosphere that contains weather is the troposphere. It is the lowest layer of the atmosphere where nearly all weather phenomena occur, such as clouds, rain, and storms.

The hole in the Ozone Layer over Antarctica has affected countries farther north, such as Chile and Argentina.

These countries are not in the 'Antarctic Region', but are affected nonetheless.

In terms of total absorbtion, it is water vapor. It absorbs around 75 to 80% of all the heat the atmosphere absorbs in total. Second place is CO2 which takes in around 5% of all warmth.

Ozone depletion is mainly caused by human-made chemicals called chlorofluorocarbons (CFCs), halons, and other ozone-depleting substances (ODS). These gases release chlorine and bromine atoms in the stratosphere, which then break down ozone molecules. This leads to a reduction in the protective ozone layer in the Earth's atmosphere.

Continued depletion of the ozone layer is likely to cause increased exposure to harmful ultraviolet (UV) radiation, which can result in higher rates of skin cancer, cataracts, and weakened immune systems in humans. It can also lead to harmful effects on marine life, plant ecosystems, and the overall balance of Earth's climate.

Humans create greenhouse gases by burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2). Cattle rearing and rice paddy fields release methane (CH4), another greenhouse gas.

Natural causes of greenhouse gases are volcano eruptions, and the rotting of any organic matter (trees, plants and animals).

The chemical compound responsible for the depletion of the ozone layer is chlorofluorocarbons (CFCs) and other halocarbons. These compounds contain chlorine and bromine atoms that can break down ozone molecules in the stratosphere.

The ozone layer is found in the stratosphere, a region of the Earth's atmosphere located about 10-30 kilometers above the Earth's surface. It plays a crucial role in absorbing the sun's ultraviolet radiation, which helps protect life on Earth from the harmful effects of too much UV exposure.
