While the choice of RCP is an important factor in the magnitude and timing of atmospheric carbon dioxide levels, our previous work that included both RCP 4.5 and RCP 8.5 found far more variance in future carbon
Scientists have found that throughout history, carbon dioxide levels and the height of the Earth's oceans, existence of its ice sheets, and other key indicators of the planet's climate have marched in near lockstep. The last time Earth had a concentration of carbon dioxide comparable to today...
Carbon dioxide levels in the atmosphere follow a fairly regular pattern, year by year. They track closely with the seasons in the northern hemisphere, rising through fall, winter, and early spring, and then decreasing through late spring and ...
Carbon dioxide sink in the Arctic Ocean from cross-shelf transport of dense Barents Sea water Andreas Rogge, Markus Janout, Nadezhda Loginova, Emilia Trudnowska, Cora Hörstmann, Claudia Wekerle, Laurent Oziel, Vibe Schourup-Kristensen, Eugenio Ruiz-Castillo, Kirstin Schulz, Vasil...
All plants depend on carbon dioxide and water for their survival, making their food by the process of photosynthesis. Carbon dioxide is found in abun?dance in the atmospheres of many other planets and their moons throughout the solar system. ...
Application of Cerling's CO2 paleobarometer to these data has significantly constrained the history of atmospheric CO2 through this time period.Results indicate that atmospheric pCO2 has significantly fluctuated throughout the Phanerozoic. High concentrations of atmospheric CO2 levels in the Late Silurian ...
Human alteration of the carbon cycle How scientists study past atmosphere and climate In an attempt to understand whether recently observed changes in the global carbon cycle are a new phenomenon, or have instead occurred throughout geologic history, scientists have devoted considerable effort to develo...
Another climate record was set in May of this year. Carbon dioxide levels in the atmosphere reached a new maximum, topping out at their highest concentration seen in all of recorded history and beyond. As measured by the Scripps Institution of Oceanogra...
we find that atmospheric carbon dioxide is strongly correlated with Antarctic temperature throughout eight glacial cycles but with significantly lower concentrations between 650,000 and 750,000 yr before present. Carbon dioxide levels are below 180 parts per million by volume (p.p.m.v.) for ...
21 August 2015 Carbon dioxide level and form of soil nitrogen regulate assimilation of atmospheric ammonia in young trees Lucas C. R. Silva1, Alveiro Salamanca-Jimenez1,2, Timothy A. Doane1 & William R. Horwath1 The influence of carbon dioxide (CO2) and soil fertility on...
