The Bad News International Coral Reef Symposium

Fort Lauderdale FL USA- The 11th International Coral Reef Symposium is at its midpoint and the word from the reef gurus is out. The buzz word now is coral reef resilience. The effects of global climate change has resulted in more acidic oceans and warmer seas. While some corals can indeed tolerate warmer seas, none of them can survive an acidic ocean. Those who have taken college chemistry or have drank Coca Cola would know. Calcium carbonate (which make up coral skeletons) will dissolve in acidic water.

The corals have had a double whammy. Increased sea temperatures result in coral bleaching where their symbiotic zooxanthellae are expelled. These symbionts provide the coral their nutrition and help them build their skeletons. Increased carbon dioxide in the air results in more carbonic acid in water. Under these conditions, corals can't build their skeletons.

Coral reefs have been poetically referred to by none other than Jacques Costueau as the "Stones Alive". Here he writes that the reef itself is a living wreath. The corals were "The Stones Alive at the Fringe of Death" By this he meant that the corals were existing at a very narrow range of ecological tolerance. The corals were not a wreath to the dead but for the living.

The word is that any carbon dioxide reduction strategies dicussed by the G8 countries and China and India are too little,too late. The scientists are now looking at focusing their attention in coral reef areas that will be least impacted by these global environmental changes. The center of coral reef diversity, the Philippines, is not in this area.

Coral reefs in the Philippines have experienced heaps of abuse over the years and global climate change may be the last proverbial straw as the sages say. There are 47 Pinoy scientists in the symposium and what we have heard and learned are not much to hope for. But there is room for hope.

The symposium organizers have put much effort in informing the public. The symposium exhibition caters to public educators and environmental advocates.There was a special workshop on why scientists can't get their message through to journalists (very timely).

So a global multisectoral movement is needed if we want to save the coral reefs.

If we fail, the corals will be a funeral wreath for the dead. And who are the dead? It is no less than us!

President Manuel Luis Quezon's Code of Ethics

Being a denizen of Kyusi, in honour of the man who gave my city its name and for being the most colourful prez the Philippines ever had, I have the pleasure to post Manuel L Quezon's Code of Ethics on his birthday. Let us profit from the wisdom of the Kastila.

1. Have Faith in the Divine Providence that guides the destinies of men and nations.

2. Love your country for it is the home of your people, the seat of your affection and the source of your happiness and well-being. It's defense is your primary duty. Be ready to sacrifice and die for it if necessary.

3. Respect the Constitution which is the expression of your sovereign will. The government is your government. It has been established for your safety and welfare. Obey the laws and see that they are observed by all and that public officials comply with their duties.

4. Pay your taxes willingly and promptly. Citizenship implies not only rights but obligations.

5. Safeguard the purity of suffrage and abide by the decisions of the…

Simoun's lamp has been lit, finally.. not by one but by the many!

"So often have we been haunted by the spectre of subversion which, with some fostering, has come to be a positive and real being, whose very name steals our serenity and makes us commit the greatest blunders... If before the reality, instead of changing the fear of one is increased, and the confusion of the other is exacerbated, then they must be left in the hands of time..."
Dr Jose Rizal "To the Filipino People and their Government"
Jose Rizal dominates the Luneta, which is sacred to the Philippine nation as a place of martyrdom. And many perhaps all of those executed in the Luneta, with the exception of the three Filipino secular priests martyred in 1872, have read Rizal's El Filibusterismo. Dr Rizal's second novel is a darker and more sinister one that its prequel but has much significance across the century and more after it was published for it preaches the need for revolution with caveats,  which are when the time is right and who will instigate it.

Flame trees in bloom

The hottest summer courtesy of El Nino in at least 10 years gave runners and walkers in the University of the Philippines Diliman campus a visual treat. This year the flame trees Delonix regia are in full bloom!
In past summers it wasn't as hot and dry so the trees did not shed their leaves and few blooms were produced.
It is the tropical version of the Japanese Hanami or the Cherry blossom viewing season. While Hanami tells us the fragile impermanence of beauty, the flame tree hanami tells us that summer burns but soon it will all be over.
