Increased carbon dioxide enhances plankton growth


CO2 is good.

“Coccolithophores–tiny calcifying plants that are part of the foundation of the marine food web–have been increasing in relative abundance in the North Atlantic over the last 45 years, as carbon input into ocean waters has increased. Their relative abundance has increased 10 times, or by an order of magnitude, during this sampling period, report researchers.”

We never expected to see the relative abundance of coccolithophores to increase 10 times in the North Atlantic over barely half a century. If anything, we expected that these sensitive calcifying algae would have decreased in the face of increasing ocean acidification (associated with increasing carbon dioxide entering the ocean from the burning of fossil-fuels). Instead, we see how these carbon-limited organisms appear to be using the extra carbon from CO2 to increase their relative abundance by an order of magnitude.





CO2 increases of 80ppm to 100ppm are normal

While CO2 has increased by 85 ppm from when measurements began  in 1958 and are estimated to have risen by 120 ppm since 1750, we should also realize that increases of 80 ppm to 100 pm occurred during the last 3 glaciations without humans burning fossil fuels.

” Air trapped in bubbles in polar ice cores constitutes an archive for the reconstruction of the global carbon cycle and the relation between greenhouse gases and climate in the past. High-resolution records from Antarctic ice cores show that carbon dioxide concentrations increased by 80 to 100 parts per million by volume 600 ± 400 years after the warming of the last three deglaciations. Despite strongly decreasing temperatures, high carbon dioxide concentrations can be sustained for thousands of years during glaciations; the size of this phase lag is probably connected to the duration of the preceding warm period, which controls the change in land ice coverage and the buildup of the terrestrial biosphere.”



CO2 from Wood/Biomass is worse than Coal

The new trendy fuel being proposed to replace the EPA/Hansen vilified coal is wood and/or biomass.

One biomass power plant “will emit 1,732 tons per day of carbon dioxide to produce 380,000 MWh of power annually, an emission rate of 3,327 lbs of CO2/MWh. For comparison carbon dioxide emission rates are 2,117 lbs/MWh for existing coal plants,  1,314 lbs/MWh for existing gas plants
and 760 lbs/MWh for new power plants.”

Lets put that in a table.

Fuel lbs of CO2/Megawatt Hour
Biomass 3,327
Coal 2,117
Older Natural Gas 1,314
New Natural Gas 760

“wood fueled biomass power plants emit about 50% more CO2 per MWh than existing coal plants, 150% more than existing natural gas plants and 330% more than new gas power plants.”

Thats right. Biomass/Wood produce 330% more CO2 than a new super-efficient natural gas power plant burning natural gas. And thanks to fracking the gas is super-cheap.

If you believe in the “CO2 will end the world scam”, then please fight hard against wood and biomass power plants. And fight hard for new natural gas power plants.

If you don’t believe, then laugh at the idiots who do. And tell them the truth.

If you are against fracking, and for biomass/wood power planets, you hate the planet.
