U.S. President Donald Trump threatened to impose tariffs on the smoke from forest fires coming from Canada. Canadian leader Mark Carney emphasized that the U.S. and Canada share equal responsibility in the fight against climate change. Experts highlight that climate change is worsening conditions for forest fires. This scenario could create serious problems in northern U.S. cities. Trump's proposal for tariffs may further escalate political issues between the two countries.
