No, that’s not how it works. That’s a 1 dimensional view.
We will have more wild variations of weather, so some places will get much, much more humid and others will get much much drier. And maybe the same place will get wetter and drier in the same season. It will be disastrous, but in a wilder and more unpredictable way.
Absolutely correct. What's happening is the increase of total energy in a titanic, global chaotic system. By definition, and even in a purely mathematical model, you'll get more intense 'outlier' events in both range and statistical behavior. In real life, exactly the same thing happens and is happening.
I agree with you, weather is different during different seasons and other factors. No matter what the global average temperature is increasing, with that is the certainty that areas affected will have increased capacity for moisture in the air. As of 2017, this is the majority of the globe, will have greater capacity for increase humidity from previous years. I've provided data showing the anomaly over time is warmer for that majority of our planet.
