The graph above shows the recent monthly mean carbon dioxide measured at Mauna Loa Observatory, Hawaii in the last five years. It is published by the National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory Global Monitoring Division.The last four complete years of the...

are a rather clear indicator of what that inaction looks like. Known as the Keeling Curve since its inception in 1958, the graph tracks the buildup of carbon dioxide in the atmosphere
The rising negative effects of climate change are caused mainly by the increase of atmospheric carbon dioxide concentrations, calling for advanced technologies to extract carbon dioxide from atmospheric air. Here we review carbon dioxide capture from atmospheric air by amine-functionalized silica composites...
Ocean acidification and atmospheric carbon Hi everyone The following graph shows levels of CO2 in the oceans increasing with atmospheric CO2. https://ocean.si.edu/conservation/acidification/ocean-acidification-graph Given that global temperatures should rise with CO2, is it theoretically possible for ...
lower than what it would be if it did not have an atmosphere to distribute heat from the dayside to the nightside. The dip in the spectrum between 4 and 5 microns (NIRCam data) can be explained by absorption of those wavelengths by carbon monoxide or carbon dioxide molecules in the ...
I’ve usually accepted the premise that increasing atmospheric carbon dioxide concentrations are due to the burning of fossil fuels by humans. After all, human emissions average around twice that which is needed to explain the observed rate of increase in the atmosphere. In other words, mankind ...
Using Fourier transformed infrared spectroscopy (FT-IR), reactive species like nitrous oxide (N2O), ozone (O3), carbon dioxide (CO2) as well as the isomerates nitric acid (HNO3) and peroxynitrous acid (ONOOH) have been found in the gas phase around the surface plasma [184]. To get ...
Following a prospective cohort design, we fitted models with reference to our a priori directed acyclic graph15 and included age, sex, marriage, education, and the penalty spline of the body-mass index as the initial predictors. We further considered temperature and precipitation in the main Cox...
Existing methods for fine-scale air quality assessment have significant gaps in their reliability. Purely data-driven methods lack any physically-based mechanisms to simulate the interactive process of air pollution, potentially leading to physically inc
