air pollution

Ryan Kennedy, an assistant professor at the Johns Hopkins University Bloomberg School of Public Health, is the author of a new study, released Thursday, which details the shocking findings of a two-year study exposing poor air quality on four Carnival Corporation ships — the largest cruise operator in the world — including one that left Vancouver for Los Angeles in October 2018.

A prominent government scientist says he felt compelled to "back down a bit" from advice about improving pollution monitoring by Environment and Climate Change Canada after getting some pushback over his proposal's modest $60,000 price tag.
