Temperature records have been smashed across the Pacific north-west over the past few days as the region continues to swelter in an unprecedented heatwave.

Weather stations at Seattle and Portland international airports have recorded their hottest-ever temperature (46.1C and 41.7C respectively) while in Vancouver, the temperature reached 32.4C, the third hottest figure since 1948.

The phenomenon is being attributed by meteorologists to a “heat dome” lingering over the northern hemisphere and trapping concentrations of hot air in place. Climate scientists say this is evidence of the ever-worsening climate crisis.
