Of course, and I apologize that it was not more clearly stated. (1) climate models project changes in climate, (2) a body of evidence is emerging that climate volatility is greater in reality than predicted by those models, eg we are on track to hit 1.5 degrees of warming in 5 years time instead of 50, (3) therefore the models were too cautious or conservative in their projection of the rate of change.
Thank you. After reading a few explanations, I think the phrase was fine. I was just parsing it in a political context, as opposed to the original meaning of the word "conservative".
Where can you find up-to-date temperature readings (as up-to-date as possible)? Are there public datasets available?
