I do not know the source of that claim you cited so I cannot answer your question. I suspect that it refers to all scientists not just those that specialize in climatology. In fact you don't need to be a scientist to understand the connection between increases in CO2 and increases in global temperature as well as ocean acidity. Any educated person can read a review or book on how human activities alter climate and learn the facts for themselves. The difficulty is finding unbiased sources of 'facts'.
