text: what is global warming? does anyone have any proof? i don't believe in global warming, until i have proof. i do believe in politics. global warming is the observed increase in the average temperature of the earth's atmosphere and oceans in recent decades. (http://dictionary.reference.com/browse/global%20warming ). it is mostly man-made and comes from everything from factories to cars. (http://www.epa.gov/ebtpages/airairpoglobalwarming.html )almost every single real scientific study links global warming directly to humans.  it's only certain political figures that don't want to change for reasons easily guessable. that is why the whole developed world signed that kyoto treaty and why every single developed country is working to reduce their polluting of the air, water, and land.   see the new gore movie, it has the backing of the scientific and political groups:   scientific community: http://www.usatoday.com/tech/science/200...  government groups:  noaa (national oceanic & atmospheric administration) on why peer-reviewed journals are the only real scientific studies to be believed: http://www.ncdc.noaa.gov/paleo/globalwar...  the epa's site for kids: http://www.epa.gov/globalwarming/kids/in...  from nasa: http://earthobservatory.nasa.gov/library...  the atmospheric radiation measurement (arm) program is an important part of the u.s. department of energy's strategy to understand global climate change: http://education.arm.gov/studyhall/warmi...  http://globalchange.gov/ http://www.fueleconomy.gov/feg/climate.s... http://marine.usgs.gov/cgi-bin/locator?s... http://www.usaid.gov/our_work/environmen... http://lwf.ncdc.noaa.gov/oa/climate/globalwarming.html  all of the above are .gov sites.  edit:   notice how the person below me offers no evidence what-so-ever.  that is exactly what is holding us back in taking real steps in fixing this very easily fixable problem.  all people like this due is try to poke holes in something that is already rock-solid in all real scientific (government) communities. hollywood, gore, or anyone else who has made this up.  it is our own government organizations, working separately, that have all come to the same conclusion.  the people who don't believe offer nothing but opinions and fake studies done by non-governmental - or none-peer reviews - organizations.  it is a real problem that can be fixed with easy measures.
