'There is no corresponding anti-snowfall record.'

Pretty sure that means that there is no record for minimum snowfall. They are max records only.

That site is in no way dedicated to there being no climate change. Primarily it takes the skeptical view on human induced global warming and/or human induced climate change. It tries to provide a counter-point to alarmism and the politicization of climate science. It also tries to expose faulty science and claims made based on faulty methodology.

it has no mention of mars:

so there is the proof you guys needed

have you thought about what it means in regards to natural warming cycles coupled with man-made pollution?
