Telling us that Dr. Tim Ball was called to Capitol Hill to meet Donald Trump's senior advisors, (who are, starting with the president, probably all climate change deniers) does little to back Jerome Hauk's argument (Gazette, Feb. 8) that human activity is insignificant in climate change.
Dr. Ball belongs to a climate change denial group called Climate Exit. I would take anything he has to say or write with a grain of salt.
