Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Lower stratospheric ozone depletion in recent decades has resulted in a negative radiative forcing (i.e. a cooling effect on the climate) and has offset, by about 15-20%, the positive greenhouse forcing due to increases in other gases.
