In order for climate change to have a change there must be a known point. As we have no known point, then climate change is an arbitary notion.
After studying over 3000 years of climate, no one has stated known norms of climate.
So BS is always allowed when no norms are allowed.
If we do not have any scientific knowledge of what is normal; then how do we know it is abnormal.
Massive weather changes is not climtae changes, just changes in weather.
