The earth's climate change is highly debated among scientist. The National Environmental satellite, data, and information service (NESDIS) has been tracking the changes for the last few years. Their sensors are able to pick up even the smallest change in climate throughout the world. They control many buoys, ships, weather stations, balloons, satellites, and aircrafts that travel the world to find information.
          Intergovernmental Panel on Climate Change (IPCC), National Oceanographic data center, World Meteorological Organization (WMO), and the United Nations Environment Program (UNEP) are all organizations that are focused on this issue. These groups get together every year and share information to predict the future of our global warming problems.
           Although the green house effect is essential for life on earth, it has become a problem. Without the green house effect the earth would be about 0°F as apposed to the 57°F it is now. Human activities which are important to our lives are part of the problem.
             Human Activity is increasing the concentration of the earth. There used to be about 280 parts per million by volume (ppmv) of carbon dioxide in the world, now there is about 370ppmv. According to most reports it will double by 2065.
             The temperature of the earth has increased .6°C since a century ago. And about .3 in the last twenty years. This warming occurs more and less rapdily in different parts of the world. Some areas have cooled. In the Eurasia area the temperature has increased 2°F in the last 25 years.
              Conterary to most people's beleifs El Nino has not effected the temperatureses.
