The CO2 concentration at the Mauna Loa observatory in Hawaii has passed 430 parts per million

When man first walked on the moon, the carbon dioxide concentration in Earth's atmosphere was 325 parts per million (ppm).

By 9/11, it was 369 ppm, and when COVID-19 shut down normal life in 2020, it had shot up to 414 parts ppm.

This week, our planet hit the highest levels ever directly recorded: 430 parts per million.

BURNABY—Unifor is raising serious concerns about the sale of one of British Columbia’s last remaining oil refineries to American energy giant Sunoco. The refinery is part of a larger list of assets across Canada being sold from Parkland to Sunoco.
