Climate change and human health changes are connected



South Florida is already coping with sea level rise.
The World Health Organization has recently published a report showing how the changing climate and health impacts are related. They divided the report into three broad categories: direct health impacts, ecosystem mediated health impacts and deferred and displacement or populations.

While all humans are predicted to face some increased health hazards from the changes, the poor and disenfranchised are expected to pay a greater price for the changes. An unexpected conclusion as I read the report was that females(human) are disproportionately affected by a warming climate. WHO made a distinction between sex – male, female – and gender roles. They opined that while physiology may play a role in the greater number of women dying in an event, the greater factor was the gender roles that women play in many cultures.

In an extreme weather event, women may be required to stay at home until a male family member gives them permission to move to safer ground, clothing may be restrictive and prevent movement in a flood situation, girls in some cultures are not taught to swim as boys often are.

Some of the effects of a warming planet have already been observed. Sea levels are increasing around the world as more of the polar ice is melting faster than it is being replenished. Some increase in sea levels may be attributed to increased use of fresh water sources which finds its way to the oceans as well.

Salt water intrusion into coastal wells and agricultural fields compromises fresh water sources and poisons the agricultural soils.

Countries normally thought of as “have nations” like those in western Europe can also be hit hard when an extreme weather event hits. In 2003 a heatwave claimed 70 000 lives in western Europe.
The “have nations” will face increasing numbers of climate refugees. Millions of people are expected to become homeless over the next 30 years due to climate changes. Even those countries that are somewhat insulated against rising temperatures will find that their traditional food crops will have to change. For instance, wheat is a cool weather crop and does not thrive in hot climates.

The massive displacement of people is also expected to trigger civil unrest. Situations of crowding and poor living conditions give rise to infections and spread of diseases.

Prince Rupert Says No to Enbridge Pipeline

Image
B. McPherson Prince Rupert city council joined a growing list of BC coastal communities that are saying “No” to the Enbridge proposal to build a twinned pipeline from Edmonton to the coast. The decision of the Prince Rupert city politicians was unanimous. Already the village of Kitimaat, Terrace and the Skeena Queen Charlottes Regional District have voiced their opposition to the project. There are ongoing hearings by a federal court appointed Joint Review Panel which are gathering input from interested parties about the proposed Enbridge Northern Gateway Pipeline which would bring crude petroleum from the oil sands of Alberta to the coast of British Columbia. The proposal would see a twinned pipeline run over the Rocky Mountains and through wilderness to the treacherous west coast. The proposed terminus at Kitimat would require tankers to wend their way through the maze of islands and reefs to load up at the head of Douglas Channel. While the hearings and the finding

Abandoned Oil Pipelines What Lurks Below?

Image
These photos were taken July 2012 in the historic Turner Valley, Alberta B. McPherson Controversy over new oil pipelines is reaching boiling point in many circles. Heated debate is taking place over the proposed Enbridge Northern Gateway and Keystone Pipeline proposals. Safety, disruption to landowners  and more are being weighed against the money to be made transporting and selling petroleum products. It got me thinking about the old pipelines. What happens to a pipeline when it is too old to use or not needed? It’s a bit of an Alice in Wonderland scene. The US laws and regulations are different from ours in Canada. The Pipeline and Gas Journal is a source of information about abandoned pipelines in Texas. Apparently a pipeline in Texas may be abandoned by a company, but it still retains ownership and may choose to reactivate the line at a later date. In the meantime, the right of way or easement is no longer maintained, but the through which the pipe extends is not free

Efficient Rail Transport May Make Pipelines Obsolete

Image
B. McPherson What happens to all the abandoned pipelines? Oil pipelines have huge direct costs to build, but they also have many hidden costs. In spite of dire warnings by environmentalist the world is demanding ever greater supplies of the black gold. For those countries that have it and market it successfully, money comes rolling in. But at what cost? An oil pipeline is a hugely complex thing. Enbridge Corp. has been battling citizens in British Columbia over its proposed Northern Gateway Pipeline and the Keystone Pipeline in the US has been stalled for months. When Big Oil needs to transport oil or bitumen to refineries, it usually gets a smooth ride to approval. Labelling energy security as a national priority, property rights are infringed upon. People in Canada cannot legally stop the installation of a pipeline across their property. The high pressure conduit is often buried only a few feet below the surface leaving crops, buildings and livestock vulnerable to a
