  1. Find more questions on Global Warming on Yahoo Answers. I do enjoying seeing answers from the science-literate people in this forum: capitalgentleman, Koshka, Darwinist, David, Elizabeth, oikos and others (excuse me if I've left you out) and Koshka and Elizabeth often provide very amusing answers.
  2. Global warming is the rise in average global temperature caused by air pollution. Humans burn fossil fuels to generate power which releases pollution into the Earth’s atmosphere. This pollution traps heat and radiation from the sun in a process known as the greenhouse effect and has resulted in rising average global temperatures, melting.
  3. Feb 05,  · Global warming is speeding up Earth’s massive ocean currents. By Paul Voosen Feb. 5, , PM. The oceans’ great continent-wrapping currents, each one moving as .
  4. Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between and ) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere.
  5. Jul 16,  · Global warming is primarily a problem of too much carbon dioxide in the atmosphere. This carbon overload is caused mainly when we burn fossil fuels like coal, oil and gas or cut down and burn forests. There are many heat-trapping gases (e.g. methane and water vapor), but CO2 puts us at the greatest risk of irreversible changes if it continues.
  6. Global warming, the phenomenon of rising average air temperatures near Earth’s surface over the past to years. Earth’s climate has changed over various timescales since the dawn of geologic time, and the force of human activities since the Industrial Revolution has been woven into the .
  7. But change is still possible. Science suggests that we can avoid the worst impacts of climate change if we limit warming to under 2ºC. To do so, we need a much cleaner economy by mid-century or sooner. Fossil fuel companies need to stop preventing climate action. And leaders in the United States need to act. You can help.
