Ocean Acidification

The Other CO2 Problem Is in Our Oceans

When carbon dioxide (CO2) is emitted into the atmosphere it doesn't just stay there -- about 25 per cent of emissions are absorbed into the ocean, increasing the acidity of the ocean. An ocean increasing in acidity is not a very friendly place for its creatures, many of which play critical roles in marine food webs and are vital sources of human food. I recently travelled to Italy and across North America investigating how ocean acidification could impact marine life. While I like to remain hopeful in most things, what I learned has made me very worried about the future of the ocean.

North Van Mayor Proposes Way Out Of Transit Rreferendum Quagmire

One innovative plan that has been considered for about a decade, but has never been funded, is a system commonly used in Europe called "headway operations." This means buses depart at regular intervals keeping the headway (time between buses) even and avoiding bunching, instead of trying vainly to stay on a fixed schedule in widely varying conditions. This is how most rapid transit systems including SkyTrain operate.

The Ocean: A Barometer for Mass Extinction

It is a scientific fact that the oceans are acidifying at an alarming rate and the impact of this will be profound. By looking at ocean vents and seeing what happens to the coral around them, we have a crystal ball for the future. The ocean is the canary in the coalmine for mass extinctions.
