Increased Carbon Dioxide Makes Climate Less Extreme

Bioenergy (wood burning) is not carbon-neutral

“There is one problem. Ecologists say that the claims of carbon neutrality, which are accepted by the European Union and the British government, do not stand up to scrutiny. The forests of North Carolina, Louisiana, and Mississippi — as well as those in Europe — are being destroyed to sustain a European fantasy about renewable energy. And with many power plants in Europe and elsewhere starting to replace coal with wood, the question of who is right is becoming ever more important.” click here

Carbon Taxes Increase Carbon Dioxide Emissions

“Instead, adopting carbon taxes in the West will actually raise global carbon emissions by offshoring economic activity from relatively environmentally-friendly places, like the USA and Germany, to places with lax environmental laws, like China.” click here

Sea Ice and Atmospheric Carbon Dioxide Unrelated

“According to climate models, anthropogenic CO2 emissions drive trends in polar sea ice.   The sea ice extent in both the Northern and Southern Hemispheres should therefore gradually decline (linearly) as human emissions rise.

However, neither the Arctic nor Antarctic sea ice trends appear to be cooperating with these modeled expectations.” click here for notrickszone.

Arctic Microbes Convert Dissolved Organic Carbon to CO2

Collin P. Ward, Sarah G. Nalven, Byron C. Crump, George W. Kling, Rose M. Cory. Photochemical alteration of organic carbon draining permafrost soils shifts microbial metabolic pathways and stimulates respiration. Nature Communications 8, Article number: 772 (2017) doi:10.1038/s41467-017-00759-2

In sunlit waters, photochemical alteration of dissolved organic carbon (DOC) impacts the microbial respiration of DOC to CO2. This coupled photochemical and biological degradation of DOC is especially critical for carbon budgets in the Arctic, where thawing permafrost soils increase opportunities for DOC oxidation to CO2 in surface waters, thereby reinforcing global warming. Here we show how and why sunlight exposure impacts microbial respiration of DOC draining permafrost soils. Sunlight significantly increases or decreases microbial respiration of DOC depending on whether photo-alteration produces or removes molecules that native microbial communities used prior to light exposure. Using high-resolution chemical and microbial approaches, we show that rates of DOC processing by microbes are likely governed by a combination of the abundance and lability of DOC exported from land to water and produced by photochemical processes, and the capacity and timescale that microbial communities have to adapt to metabolize photo-altered DOC.
