The WMO reports historically high levels of the greenhouse gasses methane and nitrous oxide, which like carbon dioxide are common byproducts of human industry.

Although the port has drastically slashed diesel exhaust and nitrogen oxides through cleaner fuels and engines in the past two decades, it is now faced with its stiffest challenge to date: adopting zero-emission technology.

In a statement read to the court, a bomb disposal officer said the device contained nitrous oxide cylinders.

“If we take large-scale efforts to reduce methane emissions — and I should say nitrous oxide as well, and other shorter-lived greenhouse gases — we could buy ourselves decades of time to reduce carbon dioxide emissions.”

It used magnesium oxide boards, which do not burn, during testing and did not reveal this in marketing literature.
