Solved by a verified expert :Atmospheric CO2 concentration by the year 2100 will be 476, and the average temperature increase over preindustrial levels will be 2.5 degrees celsius. If all things remain the same except we stop increasing the input of CO2 to the atmosphere now (year 2016), atmospheric CO2 concentration will be 464 ppm by the year 2100. The average temperature increase compared with preindustrial levels will be 2.3 degrees celsius.1) If tree removal falls 50% of its current level and the replanting of trees rises by 25%, and the CO2 pollution stops growing and actually starts to decline by 4% in all countries this year (2016), the temperature increase in degrees by the year 2100 will be what?2) If tree removal falls to 50% of its current level and the replanting of trees rises 25%, and the CO2 pollution stops growing and actually begins to decline by 2% in all countries this year (2016), the temperature increase in degrees by the year 2100 will be what?3) If tree removal falls to 50% of its current level and the replanting of trees rises by 25%, and the CO2 pollution stops growing and actually begins to decline by 2% in class countries by the year 2025, the temperature increase in degrees by the year 2100 will be what?4) If tree removal falls to 50% of its current level and the replanting of trees rises by 25%, and the carbon dioxide pollution stops growing and actually begins to decline by 4% in all countries by the year 2025, the temperature increase in degrees by the year 2100 will be what?5) If tree removal remains at 50% of its current level and the replanting of trees rises by 25%, and the carbon dioxide pollution stops growing and actually begins to decline by 2% in all countries by the year 2036 (20 years from now), the temperature increase in degrees by the year 2100 will be what?
