Black carbon aerosols — particles of carbon that rise into the atmosphere when biomass, agricultural waste, and fossil fuels are burned in an incomplete way — are important for understanding climate change, as they absorb sunlight, leading to higher atmospheric temperatures, and can also coat Arctic snow with a darker layer, reducing its reflectivity and leading to increased melting.

Although the past decade has seen a shift toward using such waste, referred to as lignocellulosic biomass, to create chemicals for producing biodegradable plastics, pharmaceuticals, cosmetics and biofuels, biorefineries have struggled with finding steady supplies and with high processing costs.

The findings show that locations on the planet with high fossil fuel emissions and biomass burning emissions are rare, suggesting an inverse relationship in which an increase in one causes a decline in the other.

In this future scenario with a high need for CDR, if the PUC had built the coal + CCS project, it could choose to retrofit the plant to a biomass + CCS power plant capable of removing carbon from the atmosphere at a relatively small incremental cost.

The capital costs associated with processing the biomass are very high.

As with plants this means more photosynthesis it means more biomass production and a higher CO2 uptake.

In addition, Sundrop Fuels is able to maximize its synthesis gas production by integrating natural gas with biomass feedstock, facilitating the most efficient utilization of hydrogen from both the biomass and natural gas to produce higher yields than any other biomass process, it says.

His position: • No evidence of increasing lake clarity as a result of secchi measurements since 1946 • The interplay of stratification and plankton productivity are not «straightforward» • Challenges O'Reilly's assumption on the correlation of wind and productivity - the highest production is on the end of the lake with the lowest winds • A strong caution using diatoms as the productivity proxy (it is one of two different lake modes) • No ability to link climate change to productivity changes • More productivity from river than allowed for in Nature Geopscience article • Externally derived nutrients control productivity for a quarter of the year • Strong indications of overfishing • No evidence of a climate and fishery production link • The current productivity of the lake is within the expected range • Doesn't challenge recent temp increase but cites temperature records do not show a temperature rise in the last century • Phytoplankton chlorophylla seems to have not materially changed from the 1970s to 1990s • Disputes O'Reilly's and Verbug's claims of increased warming and decreased productivity • Rejects Verburgs contention that changes in phytoplankton biomass (biovolume), in dissolved silica and in transparency support the idea of declining productivity.

In order to address the intermittency associated with the heavy proposed use of wind power, the report proposes to deploy offshore turbines dispersed in locations all around the country (when there is little windspeed in one location, there is likely to be high windspeed in other locations), and implement backup generation consisting of biogas, biomass, hydro, and imports to manage the remaining variability.

Increased weed and pest pressure associated with longer growing seasons and warmer winters will be an increasingly important challenge; there are already examples of earlier arrival and increased populations of some insect pests such as corn earworm.64 Furthermore, many of the most aggressive weeds, such as kudzu, benefit more than crop plants from higher atmospheric carbon dioxide, and become more resistant to herbicide control.72 Many weeds respond better than most cash crops to increasing carbon dioxide concentrations, particularly «invasive» weeds with the so - called C3 photosynthetic pathway, and with rapid and expansive growth patterns, including large allocations of below - ground biomass, such as roots.73 Research also suggests that glyphosate (for example, Roundup), the most widely - used herbicide in the United States, loses its efficacy on weeds grown at the increased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is increased.72

A value of +20 % indicates biomass yields are 20 % higher when modeled using increasing CO2 values with time (according to the SRES A1B scenario of the IPCC) instead of a fixed 390 ppm for the entire run.

And as has been conclusively demonstrated in literally thousands of scientific studies, the more CO2 we put into the air, the better plants grow, producing greater amounts of biomass and becoming more efficient at using water, and better able to cope with environmental stresses such as pollution and high temperatures.

(2) This means the total NH photosynthesizing biomass has a higher proportion of land plants which interact directly with atmospheric CO2 and hence the bulk C12 - C13 - C14 fractionation process is more characteristic of land plants and more susceptible to both the annual land cycle of air / soil temperatures and short term differences in the input to the atmosphere of C - 13 and C - 14 by anthropogenic sources.

Results from Fall et al.
