Coral reefs thrive near high CO2 seafloor vents

“Though it’s believed the 130 ppm increase in atmospheric CO2 concentration since 1750 has caused the ocean waters to “acidify”, on a daily basis 50-380°C metallic acid enriched by CO2 concentrations reaching 60,000 to 95,000 ppm pours through seafloor vents. Nearby coral reefs “thrive” in these high-CO2 conditions.” click here

“…zero-emission…is a crime against humanity.”

“The past 150 years show that affordable and reliable energy is the key to prosperity. The past 150 years also show that more CO2 is beneficial for nature, greening the Earth and increasing the yields of crops. Why do governments ignore these hard facts? Why do they do the opposite and lower the quality of life by forcing high-cost, dubious low-carbon energy technologies upon their citizens? The zero-emission act is a crime against humanity.click here

Climate sensitivity to CO2 is practically zero

Gabor Drotos, Tobias Becker, Bjorn Stevens. Global variability in radiative-convective equilibrium with a slab ocean under a wide range of CO2 concentrations. Tellus A: Dynamic Meteorology and Oceanography,

In radiative-convective equilibrium (RCE), radiative cooling of the troposphere is roughly balanced by the vaporization enthalpy set free by precipitating moist convection. Many earlier studies restricted the investigation of RCE to the dynamics of the atmosphere with constant boundary conditions including prescribed surface temperature. We investigate a GCM setup where a slab ocean is coupled to the atmosphere, and we explore a wide range of CO2 concentrations. We obtain reliable statistical quantities from thousand-year-long simulations. For moderate CO2 concentrations, we find unskewed temporal variations of 1–2 K in global mean surface temperature, with an almost constant climate sensitivity of 2 K. At CO2 concentrations beyond four times the preindustrial value, the climate sensitivity decreases to nearly zero as a result of episodic global cooling events as large as 10 K. The dynamics of these cooling events are investigated in detail and shown to be associated with an increase in large-scale low-level stratiform cloudiness in the subsiding region, which is a result of penetrative shallow convection being capped by an inversion and thus not ventilating the lower troposphere. These dynamics depend on the CO2 concentration: both through the effect of temperature on stratification and through the changing spatial scale of organization of the flow, which determines the spatial scale and temporal coherence of the stratiform cloud sheets.

Carbon capture has nothing to do with trees; not a trillion trees, not even 1 tree

“House Minority Leader Kevin McCarthy recently unveiled a series of bills aimed at spending taxpayer money on carbon capture and storage research, subsidizing ongoing capture and storage, and promoting the so-called Trillion Trees Initiative.” click here

US leads the developed world in reducing carbon emissions

“European leaders have spent years trying and pointedly failing to solve the climate crisis with regulation. Whether intentionally or not, U.S. policymakers have mostly avoided top-down solutions. And counterintuitively, or perhaps it should have been intuitive, the U.S. now leads the developed world in reducing carbon emissions.” click here

IPCC climate sensitivity overestimated

The greenhouse effect concept has been developed to explain the Earth’s elevated temperature. The prevailing theory of climate change is the anthropogenic global warming theory, which assumes that the greenhouse (GH) effect is due to the longwave (LW) absorption of 155.6 Wm-2 by GH gases and clouds. The actual warming increase to 33°C of the Earth’s surface temperature according to the present GH effect definition is the infrared downward LW radiation of 345.6 Wm-2 emitted by the atmosphere. The atmosphere’s temperature is the key element behind this radiation. According to the energy laws, it is not possible that the LW absorption of 155.6 Wm-2 by the GH gases could re-emit downward LW radiation of 345.6 Wm-2 on the Earth’s surface. In this study, the GH effect is 294.5 Wm-2, including shortwave radiation absorption by the atmosphere and the latent and sensible heating effect. This greater GH effect is a prerequisite for the present atmospheric temperature, which provides downward radiation on the surface. Clouds’ net effect is 1% based on the empirical observations. The contribution of CO2 in the GH effect is 7.3% corresponding to 2.4°C in temperature. The reproduction of CO2 radiative forcing (RF) showed the climate sensitivity RF value to be 2.16 Wm-2, which is 41.6% smaller than the 3.7 Wm-2 used by the IPCC. A climate model showing a climate sensitivity (CS) of 0.6°C matches the CO2 contribution in the GH effect, but the IPCC’s climate model showing a CS of 1.8°C or 1.2°C does not.

1884 tornado outbreak associated with low CO2

“This week in 1884, one of the worst tornado outbreaks, snowstorms and floods on record hit the US. There was flooding from Southern California to the Ohio Valley, and tornadoes from Illinois to Alabama and Texas.” click here
