UBC study finds extreme heat boosts plant water loss via cuticle breakdown
Global News segment reports on UBC assistant professor Sean Michaletz's research showing plants lose more water than expected at extreme temperatures. It explains photosynthesis, stomatal closure, cuticle breakdown at 40-50°C, and resulting limits on CO2 uptake. The report notes implications for accelerating climate change and the need to update models, ending with optimism about adaptation and policy. Sourcing centers on direct quotes from Michaletz and references the underlying lab findings; no other experts or counter-views appear.
