MANILA, Philippines — In only three decades, areas in the Philippines now home to around 6.8 million people will likely be inundated as the sea levels continue to rise.

By the end of the century, land currently occupied by 8.6 million Filipinos could be lower than the height of average annual coastal flood.

The figures are among the findings of the study produced by New Jersey-based science organization Climate Central.

The research, published in the journal Nature Communications, found that 250 million people across the globe currently live on land below current annual flood levels and 110 million live below the high tide line at present.

Using a more accurate way of calculating land elevation called CoastalDEM, the study of authors Scott Kulp and Benjamin Strauss suggests there are 5.4 million Filipinos already occupying land below annual flood levels.

Annual flood level is used to denote the water level at the shoreline that local coastal floods exceed on average once per year.

Conservative estimates

The new projections for the Philippines—an archipelago in the Pacific Ocean—are based on a relatively conservative scenario of expected changes. This assumes humans will moderately reduce warming emissions roughly in line with the 2015 Paris climate agreement’s two-degree celsius target and there will be a fairly stable Antarctica.

The numbers also used by the authors were based on a 2010 population data—100 million.

But assuming the high greenhouse gas-emissions continue unabated along with Antarctic instability, seven million Filipinos live on land that could be threatened by inundation by mid-century. By 2100, the number will rise to 13 million.

7 million Filipino below high tide line by 2050

The new data showed that 4.3 million people in the Philippines live in places that are below the high tide line.

Tideline is used to indicate the long-term average of the highest daily local tide level.

“[This] suggests that this land is protected today, possibly by coastal defenses. It is also possible that our data underestimate elevation in some places,” Peter Girard, director of communications at Climate Central, told Philstar.

Even under a highly optimistic scenario, 5.2 million Filipinos will occupy land that will be underwater at high tide by 2050. The number will increase to 6.9 million by the end of the century.

If emissions continue to rise, land currently home to 5.4 million Filipinos will fall below the level of high tide by mid-century. By 2100, the number will double to 11 million.

Vulnerable areas

The study suggests that waters threaten to consume Metro Manila—the country’s political and economic center—and areas in Bulacan facing Manila Bay.

An airport city complex is set to rise over the northern coast of Manila Bay, with environmental groups fearing that the reclamation will bring intense flooding in the coastal and low-lying areas of Bulacan and in nearby places.

Cebu City—the center of commerce, trade and education in Visayas—and Zamboanga City are also imperiled, according to the study.

The greatest effects of the sea level rise will be felt in Asia.

Mainland China, Bangladesh, India, Vietnam, Indonesia and Thailand account for roughly 75% of the 300 million people on land projected to be below average annual coastal flood levels at mid-century, the report said.

The research shows that urgent shifts in action are needed to prevent catastrophic changes across the globe, Girard said.

“Governments can take two critical actions to avoid the most severe consequence: cut carbon emissions as much and as quickly as possible to slow the pace of sea level rise,” he said.

“That will provide more time to determine how to respond to this threat and to plan and build coastal defenses to protect their citizens.”

Rising seas

In its report released last September, the United Nations-backed International Panel on Climate Change warned.

The report of the United Nations-backed Intergovernmental Panel on Climate Change released in September showed that the world’s oceans and cryosphere—glaciers and polar regions—are getting warmer, more acidic and less productive.

Sea levels are projected to rise nearly half a meter by 2100 if Earth warms 2 degrees celsius above pre-industrial levels and 84 centimeter in a 3C to 4C world.

Climate Change Commissioner Rachel Herrera earlier told Philstar that rising sea levels will likely cause more storm surges and flooding and endanger coastal communities.

“The most affected sectors will be agriculture and fisheries, impacting on fish catch and our food supply,” she said.

Global temperatures have increased 1 degree celsius above pre-industrial levels and are on track to rise another two or three degrees by 2100.

If the Paris treaty’s goal of capping warming at 1.5 to 2 degrees celsius is to be met, emissions of warming gases must drop to 50% by 2030 and to “net zero,” IPCC concluded in a report released in 2018. — with a report from Agence France-Presse

MINDANAO EARTHQUAKES: PUBLIC RELATIONS gone bad from YELLOW Yoly, a marketing specialist

yoly karma hotter

Yoly Ong, a top communications practitioner, got it all wrong with a series of statements that insulted the sensitivities of the Davao/Mindanao earthquake victims who she called Davao Disaster Survivors (a play on the DDS initials that mean Duterte Diehard Supporters). Yoly admonished the quake victims to make amends before it is too late so as to prevent more natural disasters (as in the earth swallowing them alive characteristic of really big ones) that she blamed on their popular support for the Philippine President (who she already judges to be HELL BOUND).

As she shed crocodile tears, she could not help but reveal a conspiracy to destroy her reputation thru an orchestrated and well funded campaign. She dug herself deeper by stating that she had nothing against ordinary citizens from Davao/Mindanao, her anger was directed only against the DDS (who did not deserve to be aided). Considering that the majority of the citizens in Mindanao are pro-government and thus could be labeled as DDS, then she actually insulted more people than she spared from her spite.

In the light of the fact that she is in the business of advertising, marketing, communications and public relations campaigns, she should have been the last person to be caught with her foot in her mouth. In fact, she should be the one to be advising politicians, celebrities and corporate executives on how to mitigate and minimize bad publicity. In this case she eagerly spewed fire and venom at a time when her opinion was not even being solicited. Yoly was right when she lamented she has “allowed” her politics to cloud her “better judgment” in the situation.
