  • Question: What Causes Global Warming?Answer: Scientists have determined that a number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accummulate in the atmosphere and trap heat that normally would exit into outer space.
  • driving cars, using electricity
  • While many greenhouse gases occur naturally and are needed to create the greenhouse effect that keeps the Earth warm enough to support life, human use of fossil fuels is the main source of excess greenhouse gases. By driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the atmosphere. Deforestation is another significant source of greenhouse gases, because fewer trees means less carbon dioxide conversion to oxygen.

  • When it comes to connecting the dots between climate change, extreme weather and health, the lines are clear. The earth is saying something with record heat, drought, storms and fire. Scientists are telling us this is what global warming looks like
  • Climate change will have a significant impact on the sustainability of water supplies in the coming decades. A new analysis, performed by consulting firm Tetra Tech for the Natural Resources Defense Council (NRDC), examined the effects of global warming on water supply and demand in the contiguous United States. The study found that more than 1,100 counties -- one-third of all counties in the lower 48 -- will face higher risks of water shortages by mid-century as the result of global warming. More than 400 of these counties will face extremely high risks of water shortages. Read more »
  • Each year American power plants pump more than two billion tons of carbon dioxide into the air. EPA's new standards would reduce carbon pollution and protect public health. Read more »

  • Carbon dioxide and other global warming pollutants are collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up.
  • over the past 50 years the average global temperature has increased at the fastest rate in recorded history

    Carbon Dioxide and other harmful things are piling up in our atmosphere. The bad gases are causing the global warming. Apparently, the temperature could be from 3-9 degrees higher by the end of the century.

  • Carbon pollution is the main reason our planet is getting hotter, increasing the chances of weather disasters, drought and flood and hurting our health. There are solutions. For starters, we can cut carbon pollution by reducing our dependence on fossil fuels and increasing our use of clean, renewable energy. And we can implement policies that help us prepare for flooding, drought, storms and other consequences of climate change. But first, we need national leadership that will stop ignoring what the earth and scientists are telling us about climate change -- and instead start ignoring those who continue to deny it is happening.
  • It's time to listen – and take action. There's plenty we can do

    Global warming Global warming affects the temperature of the earths atmosphere making it much much hotter or warmer than it is supposed to be. Global warming is said to be because we are consuming too much oil, producing too much carbon dioxide and doing too much deforestation.we got to stop cutting trees. Global warming is changing the climate that all living things have come to rely upon.While we fight or struggle to figure it all out, the whole planet Earth as we know it-coasts, forests, farms, and snowcapped mountains, rivers, animals and wildlife are in the small line of melting, dying, being killed, being deforested and obviously BEING POLLUTED!!!
