There are about 100,000 divers in China. Not that many considering the population. I enjoyed this WSJ article about diving a sunken part of the Great Wall of China. The water is green and visibility only 3′. Sounds like places I’ve been in Canada. One thing I noticed was that Pauli Husa needs a shorter inflator hose. It sticks out too much and will probably catch on something. From his LinkedIn profile I see he’s also a ham radio operator like me.

The US and Canada have agreed on measures to protect the Great Lakes, which has been praised by environmental groups. My father was an environmental engineer, although he dealt mostly with air pollution. He had a very pragmatic approach to his profession, and pragmatism is needed in environmental matters because there are so many variables and interests to balance.

Here’s some praise for the GoPro camera. Unfortunately, for most of the diving that I do the ambient light is much less than your average dive in Cozumel, and the low-light performance of the GoPro is terrible. I hope some day there’s a low-light version because I really like them otherwise.

I’ve only been back at the blog for about 10 days but have encountered the first report of a diver fatality.  The diver was 66 years old. No matter what shape we’re in, as we get older there’s a certain risk of having a medical issue under water. A medical issue anywhere is more likely, I suppose, but under water the chance of rescue and resuscitation are considerably less. Concentration of skills can help that by reducing the effort of diving, but sometimes you’ve got to go all out under water to rescue someone else. I suppose that means as you get older you should make sure you dive with people who know how to keep themselves out of trouble. That’s easier said than done.

The ice is melting in the Arctic and David Suzuki has spoken up about it recently. An interesting tidbit in the article is how the Republicans ignore warning about global warming except to mock the scientists who bring it up. Politics, a profession dominated by lawyers, is rife with advocacy over truth. Each side will argue what it believes will serve the usually short-term vested interests of its constituency to the point of outright lying, as many recent articles about U.S. vice-presidential candidate Paul Ryan have revealed (whose response of course is to attack the reporters, which may well be justified in some cases). My grade 11 chemistry teacher, Mr. Newman, was fond of saying that in science, 1/2 of what you believe to be true will be invalid in 10 years. That doesn’t make science wrong, it is in fact its greatest strength in the search for truth. So when politicians mock scientists because some were worried about a new ice age in the 70’s, I believe they know full well that they’re in fact making a mockery of the truth. At least I live well above sea level. Later, another article talks about being able to sail the Northwest Passage due to the lack of sea ice.

A few years ago I addressed an audience in Vancouver about “green” technology companies, in which I appeared right after the president of the David Suzuki foundation. Someone in the audience asked me what my company was doing about it, and I told them we were encouraging telecommuting and shrinking our office space, and that our downtown location encouraged people to use public transit. Someone else asked me if I thought the world would actually address the global warming issue. My reply was along the lines of “no, we are going to dig up all the oil and burn it, then we are going to start burning our crops as well to supply our energy needs”.

There’s not really much I can add to this article and video about a frisky male dolphin making advances on diver. Warning there’s explicit scenes in this video, at least if your a dolphin .

Some diver deaths in the news this week. A 66 year-old Palm Beach man died while on a routine dive. An off-duty policeman Cayman Islands policeman also died while diving.
