Global warming is one symptom of the much larger problem of human-caused climate change. “climate change” and “global warming” are often used interchangeably but have distinct meanings similarly, the terms weather and climate are sometimes confused, though they refer to events with broadly different spatial- and timescales weather refers to atmospheric conditions that . The dire forecasts of global warming hinge on a prediction that human activity will provoke a continued upsurge in atmospheric carbon dioxide many environmentalists believe that the burning of fossil fuels, the release of methane from agricultural activities, and the escape of other chemicals into the air over the next few decades will lead to .
Scientists have determined that a number of human activities are contributing to global warming learn about excess greenhouse gases. Global warming could do more than just melt polar ice it could change our maps, and displace people from cities and tropical islands see all national geogr. Global warming -- a gradual increase in planet-wide temperatures -- is now well documented and accepted by scientists as fact a panel convened by the us national research council, the nation's premier science policy body, in june 2006 voiced a high level of confidence that earth is the hottest it has been in at least 400 years, and possibly even the last 2,000 years.

The house is expected to vote this week on hconres119 expressing the sense of congress that a carbon tax is detrimental to the us economy the house passed. Global warming is primarily a problem of too much carbon dioxide (co2) in the atmosphere which acts as a blanket, trapping heat and warming the planet.
Global warming is happening now, and scientists are confident that greenhouse gases are responsible to understand what this means for humanity, it is necessary to understand what global warming is, how scientists know it's happening, and how they predict future climate.
