  • Is generated from carbon dioxide and other polluting gases known as human-made greenhouse gases
  • Teacher what are the causes of global warming?
  • One cause is when human activities increase the emission of greenhouse gases into the atmosphere and it retains more heat than necessary, causing the average temperature of the planet to increase and global warming occurs.
  • Another cause could also be the clearing of forests to create farms or pastures, or for other reasons, it causes emissions, since the trees, when cut, release the carbon they have been storing. As forests absorb carbon dioxide, its destruction also limits nature's ability to keep emissions out of the atmosphere.
  • Teacher and some other cause, what could it be?
  • teacher when did global warming start?
  • Global warming began 180 years ago, much earlier than previously believed, and was due to the impact of the industrial revolution on the climate, according to an international study published by the scientific journal "Nature."
  • Stephen Schneider first predicted global warming in 1976. This made him the leading expert and leader on global warming. In 1988 it is finally recognized that the climate is warmer than before 1880."
  • But the Irish physicist John Tyndall was the first to discover, in 1859, that gas molecules such as carbon dioxide, methane and water vapor (which today we call Greenhouse Gases or GHGs) block infrared radiation.
