Weather patterns are mostly limited to the troposphere.
the thermosphere
troposphere
Hurricanes, tornadoes, and virtually all other forms of weather occur in the lowest layer of the atmosphere, the troposphere.
All over the planet, all of the time.
TROPOSPHERE
Over the entire earth. This is why it is known as global warming.
Global warming causes bad breathing because of all the carbon emissions that are put into the air because of pollution
Global warming occurs in every season.
Global Warming
Global warming is happening everywhere on the Earth equally
The hole in the ozone layer came about because of the artificially produced gases CFCs (chlorofluorocarbons). These contained chlorine and bromine which destroyed ozone. CFCs are now banned. The ozone hole has very little to do with global warming.
If your question is really about oxygen then it is false. And oxygen is not increasing in the atmosphere. If you are talking about carbon dioxide, a gas that IS increasing in the atmosphere, then it is true. Carbon dioxide is causing the speeding up of global warming.
Floods, and because of global warming they have increased.
No, volcanoes would have nothing to do with global warming in any measurable way. Volcanoes occur for reasons outside of the issues involved with global warming.
Global warming continues to occur, as evidenced by the fact our polar ice caps are melting, and of course by global temperature records.

A tornado would occur in the troposphere, the layer closest to the Earth.
