The greenhouse effect causes an increase in global temperatures,which has contributed to global climate change. This temperatureincrease is due primarily to:
a) CO2​ and other greenhouse gases allowing moresolar radiation to penetrate Earth's surface
 Â
b) CO2​ and other greenhouse gases slowing the escapeof heat from Earth
 Â
c) the loss of ozone that trapped cooling UV radiation in theatmosphere
 Â
d) CO2 and other greenhouse gases slowing the escapeof UV radiation from Earth
