Cohler has created and run various performing/teaching clarinet festivals since 2000 including well-known clarinetists such as Philippe Cuper (Paris Opera), Alessandro Carbonare (Orchestra of St. Cecilia), Ricardo Morales (Philadelphia Orchestra), Paquito D'Rivera, Wenzel Fuchs (Berlin Philharmonic), and Luis Rossi (Chile). These include the International Clarinet Connection (2000,[31][46] 2001[47][48]), the International Clarinet and Saxophone Connection (2002),[49][50] and the International Woodwind Festival (2005, 2007,[51] 2010,[40][52] 2012[53][54]).
Cohler has been an adjudicator for international clarinet and music competitions including the 1st European Clarinet Competition (2010),[65][66] the Young Artist Competition of the International Clarinet Association (1997,[67] 2009,[68] 2015[69]), and the Canadian National Music Competition.
In the early 1990s, Cohler founded the classical music record company Ongaku Records, Inc.[75]
Climate change denial
Cohler publicly denied the scientific consensus on anthropogenic global warming, falsely claiming that "no model has ever correctly modeled any aspect of global warming",[76] even though numerous climate models have produced accurate results over several decades.[77] In another post, Cohler denied the existence of sea level rise, citing a pair of photos of the Sydney harbor as evidence,[78] a claim that is, likewise, factually incorrect.[79]
In June 2024, Cohler claimed that "NOBODY who understands advanced math, statistics, and physics, AND who takes the time to investigate the data for themselves could possibly believe in the #ClimateScam.".[80] As of 2021 over 99% of the peer reviewed scientific literature was in agreement regarding anthropogenic climate change.[81]
