Ice volcanoes, steam devils and ice pancakes show up during Okanagan’s deep freeze

Ice volcanoes, steam devils and ice pancakes show up during Okanagan’s deep freeze

Ice volcanoes have formed again along the shores of Okanagan Lake in Penticton. An ice volcano is a conical mound of ice formed over a lake via the eruption of water and slush through an ice shelf. The process is wave-driven, with wind providing the energy for the waves to cut through the ice and form the so-called volcanoes. The liquid water and slush freeze and fall back to the surface, growing the formation.

Dirty, cheap marine fuel ban will affect Canada's Arctic

Dirty, cheap marine fuel ban will affect Canada's Arctic

New rules cracking down on pollution from dirty, cheap marine fuel kicked into gear this week, placing stricter requirements on cargo vessels and cruise ships that are plying northern waters thanks to climate change. As of Jan. 1, Canada is enforcing a new UN-backed cap on the amount of sulphur allowed in heavy fuel oil (HFO) in the waters north of the 60th parallel, federal officials confirmed to National Observer on Thursday. The cap comes as Transport Canada considers a proposal to ban all HFO for ships operating in the Arctic, to address the environmental risks of oil spills.
