Why is Belgium (and Luxembourg, Switzerland, Austria, Norway) still above consumption CO2 levels per capita of 1990? While many others did go down
"Consumption-based emissions reflect the consumption and lifestyle
choices of a country’s citizens."
Via this article https://ourworldindata.org/consumption-based-co2 I see that Belgium's ...

Can the absorbtion of infrared around the 650 wavenumber in water be a substantial cause of converting that spectrum range into other spectra?
CO2 absorbs around the 15 microns wavelenght or wavenumber 650, and radiates in the same but also a somewhat wider range.
However, the top layer of the oceans seem to also convert that spectrum range. ...

How is causality between past CO$_2$ levels and fossilized plant pores proxies established?
According to Mann and Kump (2015),
Geologic proxies are characteristics of sedimentary rocks that we can
use to infer ancient environmental conditions. Climate scientists
study proxies because there ...

Can $\ce{CaCO3}$ shells contribute to $\ce{CO2}$ emissions in volcanoes within subduction zones?
CaCO3 dissolves below the Carbonate Compensation Depth (CCD).
However, this paper suggests that some CaCO3 can exist below the CCD.
My question arises from a discussion in this answer.
The question is ...

Cooling effect from the oceans in global warming
The ocean soaks up about 90 percent of the heat of climate change, because of ocean heating. When using the formula of Svante Arrhenius to calculate forcing due to atmospheric $CO_2$
$\Delta F=\alpha\...

About climate sensitivity of carbon dioxide: today compared with PETM
Due to IPCC the climate sensitivity of CO₂ very likely is 3.0 ± 1.5 ℃ for each doubling of the concentration of atmospheric CO₂.
Counting on earlier global warming using the Arrhenius formula [ΔT=λ·...
