Popa has a problem with climate change theory, which I have never even seen anyone attempt to address.
The world has been warming and cooling as long as it existed. Even in very recent history (the past 500 years), we can point to climate change and have historical evidence. In 1700 CE, there was a “Little Ice Age” in Europe.

So, why is anyone surprised that the temperature is rising a couple degrees?
And why would you assume it is due to something we are doing?
If something has been happening for thousands of years and continues to happen, it is probably happening for the same reason as always.
Does anyone know anything to address this?
