Greeenhouse effects

The causes of greenhouse effects

The man-made problems of the greenhouse effect is caused by man’s activities that emit greenhouse gases to the atmosphere by either cars factory and many more.

The most problematic of these is the burning of fossil fuels. Fossil fuels contain carbon, and when they are burnt this carbon combines with oxygen in the atmosphere to form carbon dioxide.


The symptoms (what we notice heppening)

  1. Sea level rise: the sea levels rose about 17 centimetres in the last century. The rate in the last decade, however, is nearly double that of the last century.

  2. Global temperature rise: global surface temperature show that Earth has warmed since 1880.Most with the 20 warmest years having occurred since 1981.

  3. Warming oceans: The oceans have absorbed much of this increased heat, with the top 700 meters of ocean showing warming of 0.302 degrees.

  4. Extreme events: The number of record high temperature events in the United States has been increasing.
