Global warming has been identified as a major issue for the global community. More properly this is called "Global Climate Change" as some areas may be warmer, some cooler, some wetter, some drier...
Background:
The contention of the larger number of climatologists is that human activities since the industrial revolution have increased the content of CO2, methane and other gases (Greenhouse Gases) in the atmosphere that trap solar heat. At the same time human activities have reduced the forest cover that had traditionally absorbed these same materials. They state that an increasing level of these atmospheric constituents has lead to a chain of chemical and physical changes that have increased the world's average temperature.
Observations of atmospheric gas composition, average sea water temperatures, atmospheric temperatures etc. confirm the trends and support the proposition.
Potential Impacts: 1. The sea levels may rise. Technically this may be caused by melting ice from the polar ice caps or an increase in sea height as the less dense water is less compressed. Low lying land like many Pacific Islands and Miami will be under water. 2. Serious climate changes may result from diverted ocean currents. As an example, the Gulf Stream keeps Europe warm. If the Stream is not running Europe may be much cooler and drier. Crops may not grow. 3. Ecology changes on the land could include species of animals and plants extending their range to the polar regions. Local flora and fauna may become extinct. A good example is the spread of Africanized bees and Fire Ants. Sea life may also be impacted both through the introduction of competitive species presently kept in other areas by water temperature changes, and by failure to adapt to less saline water. 4. Human society may be disrupted if changes in rainfall and temperature cause crop failure. Famine refugees may require significant humanitarian attention by the "lucky" nations.
Conflicting opinions? Yes indeed, some people don't agree! However, the problem breaks down into two potential scenarios. Either there is a basis for fear about climate change, or, there isn't. If Climate Change isn't real and we do nothing - good! Except of course many of the problems that science has identified and blamed as causing Climate Change are just plain wastes of resources, and inefficient and uneconomical practices that should be addressed anyway. A polluted, climatically steady world with no fish and no oil will be no fun at all.
If Climate Change is not real and we do all the things that we should - reduce emissions, cut fuel use, re-establish forests - we're out money (maybe) but in general the world is a better and more sustainable place. If Climate Change is real and we do nothing - we are dead or at least very miserable.
If Climate Change is real and we work to correct all our bad habits we might still be in trouble ... if it's too little and too late, but we'll go down fighting. If we succeed we live.
Because of greenhouse gases, too much heat is trapped within the Earth and this causes climate change such as natural disasters.
Greenhouse gases act to trap infrared radiation within the Earth's atmosphere, which effectively heats the Earth's surface and lower atmosphere. The increase in temperature is theorised to result in a rise in sea level (due to melting of large glaciers and sheet ice) and will reduce the pH of the oceans killing of a significant level of marine life. Additionally, the influx of fresh water from the melting ice may alter or halt ocean currents that distribute the Earth's heat, which will result in extreme weather patterns (colder north and south, hotter middle).
A:Greenhouse gases are adding to the greenhouse house effect which is affecting global warming. Gases help trap heat causing temperatures to rise affecting not only humans but animals as well. Due to the rise in temperature glaciers are melting fast threatening the animals that live there.These gases are bad for the environment because its causing global warming. With all those gases stuck in our Earth's atmosphere it will get hotter
Greenhouse gases are a needed gas in our atmosphere and are predominantly natural (well over 99%). Without greenhouse gases being present, we would be unable to survive on this planet.
Greenhouse gases are in small proportion. but these days due to careless human activities like deforestation the greenhouse gases have increased. As there are less trees there is more co2 in air. greenhouse gases have capability to increase earth's temperature. now when there is more co2, methane etc. the temperature increases and results in melting of glaciers. it causes flood in low lying islands and many organisms lose their habitat and die.
Greenhouse gasses ensure the earth remains warm enough to be habitable. Without them the earth would be too cold to live on.
Excessive greenhouse gasses can and do change the climate globally, as has happened on the planet Venus.

The greenhouse effect warms the gases in the atmosphere.
A decrease in the amount of greenhouse gases in Earth's atmosphere would result in Cooler global temperatures. This would help decrease the impact of global warming.
They slow the loss of heat
Greenhouse gases like carbon dioxide are building up in the atmosphere and causing global warming.

The geological record shows both the amount of greenhouse gasses in the atmosphere and the past temperature of the planet.
Greenhouse gases have had a significant impact on the environment.
The greenhouse effect warms the gases in the atmosphere.
The rain-forests are important to the environment because they filter gases, such as carbon and methane, common greenhouse gases, in the atmosphere. Without them, there is nothing to stop the greenhouse gases in the atmosphere. These gases then trap more heat, adding to global warming. THE GREENHOUSE EFFECT!
A decrease in the amount of greenhouse gases in Earth's atmosphere would result in Cooler global temperatures. This would help decrease the impact of global warming.
Forests and all vegetation remove carbon dioxide from the greenhouse gases in the atmosphere. Deforestation, cutting them down, means that the greenhouse effect is increasing. This is causing global warming and climate change.
They slow the loss of heat
Greenhouse gases like carbon dioxide are building up in the atmosphere and causing global warming.
Greenhouse gas hurts the environment by warming up the atmosphere. When Greenhouse gases like carbon dioxide and methane are released, they warm up the temperatures, which aids in global warming.
