reaching 1.29 in 2010. This means that the heating effect of greenhouse gases added to the atmosphere by human activities has increased by 29 percent since 1990. The air sample analyses begin in a lab ...

from expert scientist:The discussion of the link between deforestation and carbon in the atmosphere in the Introduction/Motivation is muddled. Do forests emit net carbon or just not absorb it once the ...

once again, with even lower amounts of sea ice in the Chukchi-Bering Sea, a sea-ice driven atmosphere (that is, years in which there were anomalous "bottom-up" heat flows) did not result in colder win ...

across much of the central and eastern United States was dominated by ridging in the upper atmosphere and high pressure at the surface. Both of these lead to very unfavorable conditions for widespread ...

once again broke records set just one year prior. Notably, carbon dioxide (CO2) levels in the atmosphere also reached record highs in 2020, even with an estimated 6%-7% reduction of CO2 emissions due ...

of a model in which they could represent sinks vs sources, but it only quickly explains why CO2 has increased and the effects of this increase. It's also very clear to quantitatively evaluate how muc ...

and the changes in carbon compared to oxygen, we know how much carbon is added to the atmosphere by living organisms and volcanoes (small) compared to that added by burning fossil fuels (large). Comme ...
