Brace for wild, weird weather

The weather is going to be a lot more weird.

And you better prepare for extreme events, the Climate Change Commission (CCC) warns.

In the Philippines, carbon dioxide emissions are increasing, CCC Commisioner Yeb Saño told a workshop on Environmental Leadership in Climate Change Adaptation.

The workshop was convened by the Southeast Asian Regional Center for Graduate Study and Research in Agriculture (SEARCA) and the Department of Agriculture's Bureau of Agricultural Research (DA-BAR).

The workshop was held to strengthen the capacity of community leaders who struggle to adopt and address climate change that impacts on food and agriculture.

Increasing carbon dioxide emissions reflect a worldwide trend although the Philippines absorbs more greenhouse gases than it produces, Saño said.

Carbon dioxide is a major source of greenhouse gases, so called because of their contribution to global warming. Its emissions in the country is up because of the increasing demand for electric power and transport fuels, Saño said.

Greenhouse gas emissions increased from 60,000 kilotons in 1994 compared to the 100,000 kilotons of carbon dioxide in 2000, the latest figures used by the Greenhouse Gas inventory. A kiloton is 1,000 tons.

The surprise, Saño said, is that the highest jump in emissions was caused by garbage. “People don't segregate, and they dump garbage together,” he said. Garbage emits 64 percent more methane, for example, which is 21 times more potent than carbon dioxide, he added.

If the Greenhouse Gas inventory includes land use and forestry, carbon dioxide emissions decreased from 100,737 kilotons in 1994 to 21,767 kilotons in 2000.

However, because of discrepancies between 1994 and 2000 values for forestry, forestry is often not included. In that case, carbon dioxide emissions increased by 25 percent, from 100,865 kilotons in 1994 to 126,878 kilotons in 2000.

The highest increase was caused by waste, up 63.5 percent from 7,094 kilotons in 1994 to 11,599 kilotons in 2000. The second largest increase came from the energy sector, up 39 percent from 50,038 kilotons to 69,667 kilotons in the same period.

Carbon dioxide emissions from agriculture increased by 11.69 percent, from 33,130 kilotons  to 37,002  kilotons from 1994 to 2000. Emissions from industrial processes actually decreased by 18.8 percent during the same time, from 10,603 kilotons to 8,609 kilotons.

The latest inventory, based on 2000 data, shows that carbon dioxide emission is nearly a ton (.9 tons) of carbon dioxide for about every Filipino each year. That's not including carbon dioxide emitted or absorbed by forests.

“It's way below the global average of 1.2 tons and way, way below the American average of 20 tons,” Saño said. In Southeast Asia, the highest emissions come from Indonesia, Singapore, Malaysia and Brunei; the Philippines is just ahead of Cambodia and Laos.

“We still have 'almost' enough forests to absorb that much carbon dioxide, which is about 100,000 tons each year,” he said.

“The big thing is, we are at the receiving end of carbon dioxide emissions  and one of the  countries least prepared for climate change,” Saño pointed out.

“The SEARCA and DA-BAR workshop is clearly part of the country's efforts to enhance knowledge on climate change,” he said. “It is an opportunity to transform technical people into climate change advocates.

“We need a lot of champions as the bureaucracy finds it difficult to understand climate change. This is one step towards understanding its impact and how to cope with it,” he explained.

“It will go a long way into promoting advocacy as the onset of the problem is very slow and, being humans, we tend to think it will not be drastic and will not happen tomorrow,” he said. “But we actually have a very small window to start working before it's too late.”
