“CO2 in the atmosphere has gone up 100 ppm in my lifetime,” said Kathleen Benison. a geologist at West Virginia University who researches past climates. “That’s incredibly fast geologically.”“You don’t h
Those nutrients aid the growth of phytoplankton(浮游植物),which, like other plants, takes away CO2 from the air. Second, whales themselves collect CO2 in their bodies when they eat other animals. The total amount of the gas adds up to about 33 tons over a whale's lifetime. When whales ...
Decent living standards (DLS) is a key assessment framework comprising multidimensional indicators at household, community, and national levels14,15, which reflects the basic material requirements to achieve human prosperity and well-being16. Achieving a decent life as soon as possible is of great si...

This ignores the blatant fact that CO2 in the atmosphere isn’t enclosed in glass, and when it warms via conduction at Earth's surface, air gets less dense (more buoyant) and begins rising toward space along with the non-CO2 molecules it’s mixed with via convection, taking the heat ...
The equivalent of about 1/4 of annual anthropogenic CO2 emissions is absorbed and stored by the ocean, and the sea plays the primary role in naturally removing excess atmospheric CO2 on geologic timescales. Ways of safely enhancing or augmenting this car
14.1%),27, 28 further validated by the obviously observed lattice disorder marked with red gridline in Figure 1B; for comparison, ultrathin cubic WO3 layers with much lower amount of oxygen vacancies were also fabricated through tuning the annealing atmosphere (Figures S3 and S4, Vo-poor WO3 ...
Understanding and quantifying ocean–atmosphere exchanges of the long-lived greenhouse gases carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) are important for understanding the global biogeochemical cycles of carbon and nitrogen in the context of ongoing global climate change. In this cha...
, replacement, demolition, and disposal of building materials, contributes 11% of global carbon emissions and approximately 75% of a building's total emissions over a typical 60-year lifetime Its impact is fixed at the time of construction and cannot be reduced once the building is constructed....
Result:The shapes of radiation flow are now steeper in the upper atmosphere. However the overall forcing on the surface temperature to offset the fall in outgoing radiation is about the same ~ 1.1 deg.C (ground) 1.5 deg.C (TOA). So the simple model still gives a good approximation !
