Political science masquerading as climate science insist that the gas that we humans and our animals exhale, the gas that is used by trees, flowers, fruits and other crops to grow and feed the world — carbon dioxide or CO2 — is a pollutant that must be over-taxed and over-regulated.
Far from the truth. CO2 is a useful gas, not a pollutant.
Since it is useful, the optimal carbon tax for coal in particular is not P10/ton, not P20, not P600, but zero. However, a zero tax on coal is unpopular from the world of climate alarmism, so we classify these tax rates as follows: P0 tax is optimal, P10/ton is rational, P20/ton is compromise, P600 is irrational.
Recently, eminent economist Dr. Ciel Habito made a follow-up paper, “The case for the carbon tax” and insist that the carbon tax for coal should be raised from the current P10/ton to P600/ton.
To support his claim, he used some ridiculous numbers that are peddled by the watermelon (green outside, red inside) movement. Here are two:
(1) “Dominated by CO2 (72%), GHGs trap heat… .”
Wrong. CO2 is 400 ppm or only 0.04% of all greenhouse gases (GHGs). About 95% of GHGs is water vapor — the clouds, evaporation from the seas, oceans, lakes, rivers, stomata of leaves, etc. The remaining 4%+ are methane, nitrous oxide, others.
(2) “CO2 averaged about 280 parts per million (ppm) for the last 10,000 years…In 2015… 400 ppm for the first time…. now triggering much more frequent extreme weather events.”
This is perhaps 5% geological science and 95% politics.
The Minoan, Roman, and Medieval Warm Periods (when there were no SUVs, no coal plants, no airplanes) were much warmer than the Modern Warm Period (mid-1800s to roughly 2000). There were wild swings in global warming and global cooling cycles regardless of the CO2 level. How would one call this — “much less frequent extreme weather events than today?” Garbage.
Climate change (CC) is true. All skeptics recognize climate change, recognize global warming. Planet Earth is 4.6 billion years old and there were climate change all those years because climate change is cyclical (warming-cooling-warming-cooling…) and natural. Global warming is true, and so is global cooling.
It is political science that masquerades as climate science to say that there is no climate cycle, that there is no global cooling that takes place after global warming.
BACK TO COAL POWER.
From the recent energy and economic experience of our neighbors in Asia and some industrial countries in the world, the hard lessons are these: (a) Countries that have coal consumption of at least 2.1x expansion over the past two decades are also those that experienced fast GDP growth of at least 3x expansion.
Prominent examples are China, India, South Korea, Indonesia, Vietnam, Malaysia, Philippines, and even Pakistan. And (b) Philippines’ coal consumption is small compared to its neighbors; its 2016 use is just nearly 1/2 of Malaysia and Vietnam’s, just 1/3 of Taiwan’s and almost 1/5 of Indonesia’s, 1/6 of South Korea’s, 1/9 of Japan’s. (see table)
A high carbon tax is irrationalI have repeatedly argued that CO2 is a useful gas. For those who insist that CO2 is a pollutant, they can certainly help curb further CO2 emission even without legislation and carbon taxation through the following:
- Stop breathing too often; more exhalation means more CO2 emission.
- Stop adopting pets (if any), stop eating chicken, pork, meat because these animals exhale CO2.
- Stop using their cars, not even jeepneys or buses, they emit CO2; skateboards and bicycles only.
- Stop riding airplanes and motorized boats, they emit CO2; solar planes or big kites and sailboats only.
- Stop connecting from the grid and from Meralco because 48% of nationwide electricity generation comes from coal; no gensets either. Use only solar-wind-biomass + candles at home.
- Tell their friends, business associates, family members, to do the same so that there will be more people emitting less CO2.
The Habito proposal of more expensive electricity via P600/ton carbon tax on coal is dangerous because while the Senate version of TRAIN adopts a P20/ton excise tax, the P600 can spring up somewhere during the final and Bicameral Committee meeting. The proposal should be exposed as based on political science, not geological or climate science.
