The point is that there is a different way of looking at it. Increased heat is only dangerous if people die from it. The reason why people don't die from excess heat today the way they did decades ago is because we have abundant access to AC and energy / power. Ergo if we see increases in deaths due to extreme heat then it is because of TWO causes that occur simultaneously:
a) Extreme heat. One can argue that this is NOT a new event. Or, one can argue that this is occurring more frequently.
b) We don't have sufficient power to protect people from extreme head (i.e. by using air conditioning).
This is one of the things that many climate alarmist miss.... That, despite the fact that we have much greater populations in high risk coastal communities, we've seen deaths due to weather / climate events go down dramatically. Why? Because we have advance human understanding of how to deal with them. This is despite the increase in temperatures that have occurred in the last 100 years. The stats would suggest that this trend (of fewer deaths per capita due to climate events) will likely continue.
This trend was (at least partially) due to how the use of fossil fuels have advanced our lives. Especially in the case of heat deaths and air conditioning. Ergo if the trend reverses and goes up, it is reasonable to suspect that this is due to the climate alarmists preventing us from have the kind of power supply that has saved us from such events in the past.
The logic behind this premise is not all that complicated.
Now, your logic is simple as well. Hotter temperatures due to climate change = deaths due to CO2 emissions. And, I get it. But, the trend of climate related deaths over the last 100 years doesn't seem to agree with that logic. In fact, it directly contradicts it.
