What is global warming we need to know ASAP?

Question

can u post ani answeres asap on global warming

Answer 1

Some gases in the atmosphere are transparent to visible light, but block heat. They let sunlight in and block the resulting heat. That's the greenhouse effect. It's like how the glass in a greenhouse keeps plants warm in winter. It's largely natural, desirable, and caused by water vapor.

Global warming is excess greenhouse effect caused by man, chiefly through burning fossil fuels and making carbon dioxide. It threatens to cause very costly flooding and serious damage to agriculture.

Answer 2

Reading the popular media can lead a person to conclude that "global warming" is:
o- either a hoax to promote business opportunities, politicians agenda and scientists grant money.....
OR
o- a problem related to overpopulation, industrialization and fossil fuels whose solution options lie in solar power, wind power, geothermal power and nuclear fusion....

However, the correct answer may be altogether different:

NASA has released never-before-seen images that show the sun's magnetic field is much more turbulent and dynamic than previously known. The international spacecraft Hinode, formerly known as Solar B, took the images. Hinode was launched Sept. 23 to study the sun's magnetic field and its explosive energy. National Aeronautics and Space Administration scientists said the spacecraft's uninterrupted high-resolution observations of the sun are expected to have an impact on solar physics comparable to the Hubble Space Telescope's impact on astronomy. "For the first time, we are now able to make out tiny granules of hot gas that rise and fall in the sun's magnetized atmosphere," said Dick Fisher, director of NASA's Heliophyics Division. "These images will open a new era of study on some of the sun's processes that effect Earth, astronauts, orbiting satellites and the solar system." Hinode is a collaborative mission led by
the Japan Aerospace Exploration Agency and includes the European Space Agency and Britain's Particle Physics Astronomy Research
Council. NASA's Marshall Space Flight Center in Huntsville, Ala., managed the development of the Hinode's scientific instrumentation provided by industry and federal agencies.

>>> as regards alternative energy methods, I favor development of the technology for nuclear fusion using lunar Helium 3

Answer 3

Global warming is an increase in the average temperature of the Earth. There are many factors that may contribute to global warming, including, pollution, over-population, precipitation, and the temperature of the sun.
