>> No one has a clue what the normal climate should be I can live with that part. >> because it has been changing continuously for billions of years. Not quite. We can certainly ascertain the rate of change and see that the rate of change in recent times has been order of magnitude faster than before. This is not normal. >> Toronto creates it's own weather like other built up areas. So we are back to confusing local weather with global climate? The global average temperatures are not measured by averaging city thermometers. The two major sources are ocean water temperature (no buildings there to affect them) and global observations by satellites across the arctics, deserts, oceans, etc. >> The geological record clearly shows that the past has been a lot warmer and a lot colder than the present in all locations on earth. How does that dispute the effect of man made activities on increasing rate of change?
