2. This is influencing the climate and the earth's temperature which is leading to global warming.
3. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere.
4. The 500-year perspective allows science to determine exactly when the warming trends that the earth is witnessing started.
5. It is found that in the tropical oceans and over Northern Hemisphere continents the earliest signs of warming developed around the 1830s to 1850s.
