I'm a Podcaster Now

We had some (unusual) significant rainfalls the last few days, which are finally putting the Brisbane dam levels above 40% (later today), the first time they have reached that level since 2005. There will be some easing of water restrictions, but nothing that will really matter until the dams reach 60%. With all this wet weather has come some cold temperatures, which have caused many of my colleagues to "rug up" like the girl in this photo. The max yesterday was around 14 C (57.2 F), which is frigid for longtime Queenslanders, most of whom don't have any real heat in their homes. As for me, I find this weather quite nice!

This week I began giving lectures for the second semester at UQ. I'm teaching a new course, Social Neuroscience, which I'm really excited about because the topic is very close to my core interests. But it also requires a lot of preparation because I am having to read a lot of new research that has been published only in the last 2-3 years. As part of the course, I'm recording my lectures as video podcasts. I have some software on my laptop that records the slides the students are seeing while also recording the audio. I am making the podcasts available on my socialneuro website, where you can even subscribe to the entire course via your local iTunes app. Listening to myself, however, makes me wish for a low, deeply resonating voice like you hear on FM radio. A guy can dream...

Denial: It's Not a River

At long last, SE Queensland has been getting some very good rainfalls this week.  There's a vibrant green everywhere, which I have never seen before in my previous wintertime visits to Brisbane.  Still, the drought continues because we are still woefully down on the annual rainfall total, which has been the case for several years.  I find the graph below, which is updated every day, especially scary.  The dams represented here comprise the major water supply for the Brisbane metropolitan area.  The largest dam is Wivenhoe, which is at less than 16% capacity.  Somerset is at 35% capacity, but it is a much smaller reservoir.  
Note that the black line, which represents the total system capacity, hasn't been above 30% capacity for 18 months.  Even with the recent rainfall, there hasn't been much of an increase above 20% in the last six months.   I find numbers very convincing.  As the experts keep saying, unless we get a weather event equivalent to a cyclone, with heavy rains in the catchment areas that last for several days, we aren't going to see those lines going back up anytime soon.  By the way, this information is freely available and publicly repeated nearly every day.

Thus, reading the following comments from the Courier-Mail web site left me stymied.  How can anyone think that this 'drought' is actually some sort of government conspiracy to increase revenue?  Why do some people have such a difficult time understanding that there are always limitations to our natural resources?  And, if you live on the driest continent on the planet, how can you not think that we have to be particularly careful about our use of water?  A few examples of The Denial:
  • though that this was supposed to be all taken care of after the 1974 flooding so we don't have this risk anymore? while i love the fact that we are getting the rain is the local government infrustructer really up to the weather we are about to be facing over this year and next? the state take over of the watter supply is not going to change anything and i think even if we got all the dames full they would try to take us all up to level 7 or 8 watter restrictions... they ate now seeing that there is money in watter and in fines and while they are the government they know they can do what ever they like and every1 eats must play along. after all last time the dames got 3 months i think it was instead of keeping to the old planed time table for the higher restrictions they moved it flowered i mean really how much of a mushroom are we in Queensland? and how much longer are the government going to be feeding u crap for!!!  Posted by: Mark Brown 12:52am today
  • an independent surveyor should be engaged to tell us exactly how much water is in our dams, as i dont belive the crap the government and media reports on a daly basis, and i agree with mark brown the government will tell us lies for as long as possible to extract every last cent out of us to pay for there billion dollar blow out of the water grid,  Posted by: global warming my ar@# of qld 7:29am today

Praying for Rain

As most of you know, I moved from Atlanta, Georgia, to Brisbane, Queensland, this past June. Without intending to do so, we also stayed within the same Köppen climate classification group and subdivision: Group C: Temperate/mesothermal climate, Humid Subtropical. World cities in this group include Houston, Milan, Brisbane, Atlanta, Yalta (Ukraine), Porto Alegre (Brazil), and Luodian (China). What’s more, we moved from one drought-stricken city to another. As soon as we got here, “saving water,” “Level 5 restrictions,” and “Dam area catchments” became a regular part of our daily conversations. People here have been madly buying rain water tanks for months…so much so, that there was a shortage of tanks back in July. Huge public works projects are going on so that a large pipe grid can more easily shift water from wetter parts of the region to dryer ones. Households face restrictions based on the number of their occupants. Four-minute showers are the norm. And Level 6 restrictions go into effect next week, which will severely limit the amount of water businesses can use. I have friends involved with both the pipe grid project and the public education campaign for Queensland, and I am impressed how everything is proceeding, despite the fact that the dams are now less than 20% of their capacity.

As I said, I left Atlanta in the middle of a similar drought back in July. The only noticeable sign of the Atlanta drought back then was that people were restricted to watering their lawns at only certain times on certain days. That was it. When I visited in October, those watering restrictions were more severe (although the lawns still looked surprisingly green in my old neighborhood), but nothing else had been done. There was a mild ruckus when the Stone Mountain amusement park announced its plans would proceed for building a snow mountain in August (with temps reaching into the 90s), even though they would be using public water from the county, rather than from the lakes in the park. I also heard the governor of Georgia, Sonny Perdue, make an impassioned plea that FEMA send water trucks to Atlanta to help out. Lots of blame was put on the federal engineers who control the water at Lake Lanier, the primary reservoir for metro Atlanta, but it’s clear that the lake would run out of water anyway, regardless of whether they stopped releasing any more into the Chattahoochee. In October golf courses were still allowed to water their massive turfs. There was no talk of rain tanks, no public campaign to urge people to conserve their water usage, and no proposed long-term plan to deal with future droughts. Still, Lake Lanier could run out of water in a matter of months, if there isn’t a significant rainfall soon. And Atlanta is now entering the driest part of the year.

Well, Georgia has come up with a plan that I don’t think Queensland has thought about yet—prayer! Yes, the governor gathered a group of people on the steps of the state capitol to pray for rain on Tuesday. Interestingly, he acknowledged that the people of Georgia have been a bit shortsighted:

“We acknowledge our wastefulness. We acknowledge that we haven’t done the things we need to do. Father, forgive us and lead us to honor you as you honor us with the showers of blessing.”

I am convinced that we are going to see increasing problems around the world due to water shortages. Populations in the driest parts of the world have nearly all exceeded their local water capacities, and it’s only going to get worse. Maybe praying can help, but we all should be planning and acting now before the pipes run dry.
============================
UPDATE: I just found this New York Times story about one BIG water user, who says he only recently became aware of the severity of the drought in Atlanta:

ATLANTA, Nov. 14 — A day after Gov. Sonny Perdue asked God to forgive Georgia for being wasteful with its water, county officials in the wealthy suburbs northeast of Atlanta confirmed Wednesday just how profligate one consumer had been.

A homeowner in Marietta, Ga., used 440,000 gallons in September, or about 14,700 gallons a day. By comparison, the average consumption in the United States is about 150 gallons a day per person, and in the Atlanta metropolitan area about 183 gallons.

Month after month during a record-setting drought, the two-story, five-bedroom home owned by that consumer, Chris G. Carlos, a wealthy investor who is a member of one of Atlanta’s most well known and philanthropic families, has topped Cobb County’s list of residential users.

Robert Quigley, a spokesman for the Cobb County Water System, said Mr. Carlos had used an average of 260,000 gallons of water a month for the last year, about twice as much as the consumer next-highest on the county’s list. Mr. Carlos has apparently been using the water not only to flush nine toilets and maintain a swimming pool but also to refresh nearly four acres of lush landscaping around his white-columned, red brick home. click here for the rest of the story...
