Did anyone here bother to read the actual memo?
It sums up Smol's research, which didn't find what it expected to find - a decrease in zooplankton levels over time where contamination from wind-blown contaminants could cause that. Instead, according to the memo, the result of his study was that zooplankton population levels had remained relatively constant. That was true even though he was testing lakes with contaminant levels 2.5 to 23 times higher than pre-development levels.
He decided to explain this failure of result away through global warming and said that without global warming we'd have seen a reduction in population. (The water got warmer, so there were more zooplankton, but there'd be even more if there wasn't an toxin.") You can't make a claim about a result you didn't see. He didn't compare those lakes to pristine lakes at the same time. He was only checking the levels in the contaminated lakes.
Queen's University supplied the report (un-allowed) to media outlets, with a technical explanation from Smol. He then went on to do interviews and made claims that there was "a smoking gun" result when his results, if represented truthful fully by this memo, don't show that at all.
Their only direct statement about Smol's behavior was this:
The advance briefing by Queen's University and the statements would indicate a lack of neutrality in the study participants and are not in line with the study findings.
If they correctly represented what occurred in this internal memo, then they're not making any outrageous claims against him. He did make statements that don't match his findings, and do require further study before any claim could have or should have been made. He certainly didn't get a "smoking gun" result.
Their own "conclusion" after reviewing all the information about Smol's research, and other similar research conducted at the same time was to: perform further studies.
