Its 2019.  You are still wondering if wanting to discuss it.  Dont know what nasa thinks.  How about you do some research.

I did research but I did not find the answers to my questions. 
  
 How much of the increase in temperature is directly attributed to humans? In percentages. 
  
 How much will a reduction in human-generated CO2 slow down the increase in temperature? In percentages. 
  
 Did not find any position from NASA on this. If they have answered this, some links would be appreciated.
