Based on my search of official Canadian parliamentary records, the claim that Adam van Koeverden said Conservatives are "burying their heads in the sand" is accurate.

Reasoning:

• Adam van Koeverden, Secretary of State for Sport, made this statement during official House of Commons Debates (Hansard No. 75) on January 28, 2026¹.
• The exact quote from the parliamentary record is: "The Conservatives can continue to bury their heads in the sand and pretend that climate change does not exist"¹.
• The context was a discussion about food inflation and climate change, where van Koeverden was criticizing Conservative Party members for what he characterized as climate change denial¹.
• Van Koeverden has been a Liberal Member of Parliament since 2019 and currently serves as Secretary of State for Sport in Prime Minister Mark Carney's Cabinet².

Overall validity: 100%
