IPCC assumptions of human CO2 emissions are invalid

“The United Nations Intergovernmental Panel on Climate Change (IPCC) climate theory assumes nature is constant. This assumption forces IPCC’s invalid claim that human emissions have caused all the increase in atmospheric CO2 above 280 ppm. IPCC’s argument to support its failed theory also fails logic because the argument itself assumes nature is constant.

IPCC’s theory cannot simulate the carbon-14 data from 1965 to 1995. The carbon-14 data prove human CO2 does not “reduce the buffer capacity of the carbonate system” as IPCC claims.

A Simple Model, based only on the continuity equation with CO2 outflow proportional to level, exactly replicates the carbon-14 data. The Model shows CO2 emissions do not accumulate in the atmosphere as IPCC theory claims but set balance levels for CO2.

Present human emissions increase the level by 18 ppm and present natural emissions increase the level by 392 ppm to produce today’s total level of 410 ppm.

The Simple Model requires us to think in a new paradigm about how CO2 flows into and out of our atmosphere. It changes entirely the dominant worldview of how human emissions change the level of CO2 in our atmosphere.” click here

“Carbon dioxide is just like any other gas.”

“Carbon dioxide is just like any other gas.  Just like the ideal gas law, Boyle’s law, Charles’s law, Gay-Lussac’s law.  Carbon dioxide isn’t any different than any other gas in those laws.  And we’ve discovered that there’s a continuum across our solar system of the way atmosphere’s work: it’s strictly a function – the warmth that we experience – is due to two things: [1] distance from the Sun (which means how much solar energy we get), and [2] the amount of atmosphere we have, the atmospheric pressure that we experience here on the surface.” click here

Is there an underground carbon bomb waiting to blow up?

Suzanne B. Hodgkins et al. Tropical peatland carbon storage linked to global latitudinal trends in peat recalcitrance. Nature Communications. volume 9, A3640 (2018)

Peatlands represent large terrestrial carbon banks. Given that most peat accumulates in boreal regions, where low temperatures and water saturation preserve organic matter, the existence of peat in (sub)tropical regions remains enigmatic. Here we examined peat and plant chemistry across a latitudinal transect from the Arctic to the tropics. Near-surface low-latitude peat has lower carbohydrate and greater aromatic content than near-surface high-latitude peat, creating a reduced oxidation state and resulting recalcitrance. This recalcitrance allows peat to persist in the (sub)tropics despite warm temperatures. Because we observed similar declines in carbohydrate content with depth in high-latitude peat, our data explain recent field-scale deep peat warming experiments in which catotelm (deeper) peat remained stable despite temperature increases up to 9 °C. We suggest that high-latitude deep peat reservoirs may be stabilized in the face of climate change by their ultimately lower carbohydrate and higher aromatic composition, similar to tropical peats.

Decarbonization is unproductive, undermines community sustainability

“Batten down the hatches! A tsunami of global warming and “clean energy” propaganda is approaching! San Francisco is hosting the September 12-14 Global Climate Action Summit, a massive event at which “international and local leaders from states, regions, cities, businesses, investors and civil society … will be joined by national government leaders, scientists, students, nonprofits and others … [to share] what they have achieved to date and commit to doing more to usher in the era of decarbonization.” ” click here

Nature the primary contributor to atmospheric carbon dioxide

Increase in atmospheric CO2 attributed to deep Pacific Ocean

Jianghui Du, Brian A. Haley, Alan C. Mix, Maureen H. Walczak & Summer K. Praetorius. Flushing of the deep Pacific Ocean and the deglacial rise of atmospheric CO2 concentrations Nature Geoscience (2018)

During the last deglaciation (19,000–9,000 years ago), atmospheric CO2 increased by about 80 ppm. Understanding the mechanisms responsible for this change is a central theme of palaeoclimatology, relevant for predicting future CO2 transfers in a warming world. Deglacial CO2 rise hypothetically tapped an accumulated deep Pacific carbon reservoir, but the processes remain elusive as they are underconstrained by existing tracers. Here we report high-resolution authigenic neodymium isotope data in North Pacific sediment cores and infer abyssal Pacific overturning weaker than today during the Last Glacial Maximum but intermittently stronger during steps of deglacial CO2 rise. Radiocarbon evidence suggestive of relatively ‘old’ deglacial deep Pacific water is reinterpreted here as an increase in preformed 14C age of subsurface waters sourced near Antarctica, consistent with movement of aged carbon out of the deep ocean and release of CO2 to the atmosphere during the abyssal flushing events. The timing of neodymium isotope changes suggests that deglacial acceleration of Pacific abyssal circulation tracked Southern Hemisphere warming, sea-ice retreat and increase of mean ocean temperature. The inferred magnitude of circulation changes is consistent with deep Pacific flushing as a significant, and perhaps dominant, control of the deglacial rise of atmospheric CO2.
