One more for the list. The ozon hole over the Arktis has never been bigger. Get out the sun cremes
That's incorrect, buddy. The ozone hole has a cycle. It starts to form in August, and shrinks around year-end. Most countries acted very fast back in the 80s when the hole was discovered (by banning chloroflourocarbons), and the ozone layer is slowly recovering. Recovery speed varies, it's currently at its lowest.
Current projections put and end date to the hole between 2050 and 2060.

You can monitor the ozone layer, atmospheric CO2 and other related atmospheric data in the Copernicus Atmosphere Monitoring Service (an EU's environmental observation office).
