Ozone layer in stratosphere has 10 ppm of ozone O3 which absorbs 98% of UV radiation coming from sun.

The video I quoted elsewhere answers your question - From memory - as the ozone hole grows, the upper atmosphere temperature drops which allows heat conduction to be more efficient and allows more heat to escape from the Earth more rapidly. This is partially why despite all of the claims, the temperature of the Earth has been falling since the 1940's and not rising.

NASA's temperature records are all phony. They are showing temperatures in areas all over the globe in which no weather stations exist. While those in the US are seriously impeded by the Urban Heat Island Effect nevertheless using JUST the US ground based thermometer temperature records the temperature is falling and has been since WW II. This is backed up by the number of "Over 100 degree days" in most major cities having fallen dramatically since then.

While the US is only a third of the northern hemisphere it is the only one with absolutely continuous weather recordings since the civil war.

Though spottier, the European records pretty much match the US.

No. Ozone absorbing UV does not convert to thermal energy. It converts to chemical reactions.

The formation of ozone from oxygen is an endothermic reaction. It cools the air around it when it runs. This takes place at and just above the tropopause. It is why the tropopause is so cold.
