The greenhouse gas levels were measured at the China Global Atmosphere Watch Baseline Observatory on Mount Waliguan in Qinghai province. Located on the Qinghai-Tibet Plateau, its data has proved to be close to levels measured at stations overseas that are near or at a similar latitude. The Wali...
Located on the Qinghai-Tibet Plateau, its data has proved to be close to levels measured at stations overseas that are near or at a similar latitude. The Waliguan observatory took part in the World Meteorological Organization's Global Atmosphere Watch program, along with 30 other participants. T...

green algae; carbon metabolism; photosynthetic capacity; lipids; ATP levels1. Introduction Increasing CO2 concentrations are accumulating in the lower layers of the atmosphere, causing the well-known greenhouse effect and subsequently global warming [1]. CO2 is the largest contributor, being responsible...
Average annual atmospheric levels of carbon dioxide (CO₂) reached a record high of 421.08 parts per million (ppm) in 2023. Monthly atmospheric CO₂ concentrations peaked that year in May, at 424 ppm. Human activities have caused CO₂ concentrations to soar Annual CO₂ concentrations con...
up-regulated under carbon-rich conditions, it was inferred that it could be participating in electron transfer and ATP synthesis during photosynthesis. The relative expression levels of three photosynthesis-related genes, gene33346, gene33340 and gene33386, were consistent with their FPKM values. In ...
It is important that emissions must be bounded in the long run and approach a finite steady-state level despite positive growth in GDP per capita (Ordás Criado et al., 2011). Information on whether CO2 converges at the global level or only at the country/region-specific levels, the ...
Let me explain.For millions of years,carbondioxidelevels in the atmosphere have been regulated, in part, by a natural partnership between plants and microbes – tiny organisms in the soil.Plants absorb CO2 from the air and transform it intosugars (Q33)and other carbon-based substances.While a...
Projecting electricity costs is apparently the most variable part of this calculation and was allocated at three levels: (i) minimal additional electricity costs of 0.025 €/kWh assumed for peak "surplus" electricity62; (ii) photovoltaic electricity costs in 2021 of about 0.058 €/kWh63, (iii)...
It is noteworthy that interglacial MS levels during the early Pleistocene (99 ± 28) are generally lower than those during the last 800 ky (154 ± 28), and most of the MS values (78 ± 11) of our 1.7–1.5 Ma samples fall below the MS range (99–227) over the...
