Fact: Global warming is real, and caused predominantly by human consumption of fossil fuel.
Myth: Global warming stopped in the 1990s, and earth has not warmed since.
Myth: CO2 only lags temperature change, it never precedes it.
Myth: Global warming is caused by solar cycles.
Myth: During the medieval warm period earth was hotter than it is today.
Anthropogenic (man-made) global warming is occurring. Global warming has been identified as a major issue for the global community. This is causing Global Climate Change and 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 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.
Another five:
1. The Antarctic is losing ice
2. Sea levels are rising
3. Polar bears are currently dying due to global warming
4. This warming trend started in 1850
5. That there is a general conscience between scientists
That its not true and bent

Global Warming.
True global warming does not decrease temperatures. So, either the model for global warming's effects is hokus-pokus, or global warming as presently claimed, does not exist. Some global warming followers will have you believe that global warming makes the weather "act crazy". If true, then it is not really global warming, is it.
Global warming in itself isn't pollution - global warming is the gradual warming of the earth. However, global warming was caused by carbon dioxide pollution in the atmosphere, but global warming in itself isn't a pollution. yes it is a pollution
Global warming is not important.Global warming isn't happening.Global warming is happening but it's not our fault.Global warming is happening but we can't do anything about it.Scientists are not sure about global warming.

global warming!!!!!!
Some global warning facts are that the earth has raised in temperature an average of 1.4 degrees Fahrenheit since the year 1880. Arctic ice caps are rapidly disappearing due to global warming, and coral reefs are experiencing more bleaching in the waters causing them to die off.
Fact about global warming are most trustworthy on science websites as well as Wikipedia. The best sites for that might also include regional and national sites with news.
