The combustion of fossil fuel acts as a principal source of carbon dioxide (CO2) and is still contributing to its continuous rise in the atmosphere. The levels of CO2 in the atmosphere have significantly increased since the preindustrial era and future projections predict that its concentration ...
Since the industrial revolution, there has been a steady increase in CO2 emissions into the environment, creating a global climate dilemma of how to reduce such greenhouse gas (GHG) emissions [1], [2], [313]. The CO2 levels have risen from nearly 280 ppm around the time of the industrial...
Since the start of the industrial revolution, carbon dioxide (CO2) levels in the atmosphere have increased dramatically (from 278 ppm pre-industrial to currently 417 ppm) (Rudd2022). CO2absorbs and radiates heat and is the most important greenhouse gas. The oceans are the greatest ally against ...
Cu 2 O/SnO 2 Heterostructures: Role of the Synthesis Procedure on PEC CO 2 Conversion Addressing the urgent need to mitigate increasing levels of CO2 in the atmosphere and combat global warming, the development of earth-abundant catalysts fo... Zoli, Maddalena,Guzmán, Hilmar,Sacco, Adriano,....
With rising levels of CO2 in our atmosphere, technologies capable of converting CO2 into useful products have become more valuable. The field of electrochemical CO2 reduction is reviewed here, with sections on mechanism, formate (formic acid) production, carbon monoxide production, reduction to higher...
Changes in the atmospheric reservoir of CO2 occur when there is an imbalance between surface sources and sinks of CO2. While the global land and ocean areas emit approximately 30 times as much CO2 into the atmosphere as humans produce from burning of fossil fuels, they also absorb about an eq...
returns CO2recently fixed by the forest vegetation to the atmosphere. Our results expose a positive feedback mechanism within the C budget of forested catchments, where stream CO2emissions will be highly sensitive to changes in forest C allocation patterns associated with climate and land-use ...

Although different national recommendations and standards exist that suggest different indoor CO2 levels [9,15] a frequently used CO2 limit for indoor space is 1000 ppm. In our previous study [4] a 34% of questionnaire respondents confirmed that they smoke inside their dwellings. The international...
These GHG emissions result in increased concentrations in the atmosphere, contributing to climate change12,13. One of the key advantages of using a renewable feedstock is that annually renew- able resources take carbon dioxide from the atmosphere, reducing the impact ...
