… future climate change. Although it is clear that sustainably reducing the warming influence of
greenhouse gases will be possible only with substantial cuts in emissions of CO 2 , … sources
and sinks of non-CO 2 GHGs and the potential for their magnitudes to change with climate. …

… CO 2 emissions and total global greenhouse gas emissions are reported for 2016. Total
global greenhouse gas emissions continued to increase by about 0.5% in 2016, reaching
49.3 gigatonnes in CO 2 equivalent. …

… CO 2 using proxies are crucial for understanding the Cretaceous “greenhouse.” In this paper
we summarize the major approaches for reconstructing CO 2 based on paleobotanical or
geochemical data, and synthesize the CO 2 … CO 2 , climate change, and geological events. …

… The link between CO 2 and climate warming has caught the attention of scientists and
politicians, as well as the general public, via the well… how widely atmospheric CO 2 would have
to vary in order to bring about changes to both colder and warmer climates sufficient to explain …

… of long-lived greenhouse gases that contribute to radiative climate forcing, CO2 and N2 O …
long-lived greenhouse gases due to CO2 is now over 90%, up from about 50% before 1990. …
to changes in atmospheric gases that absorb Earth infrared radiation (greenhouse gases) and …

… of the historical contribution of emissions to climate change (7). To date, research has
tracked the causal chain of climate change from human activities to greenhouse gas emissions,
to radiative forcing, and finally to climate change. However, this conventional methodological …

… To calculate national and regional contributions to climate change, we used cumulative CO
2 -equivalent emissions based on Global … Cumulative CO 2 -equivalent emissions is the most
commonly used indicator for national contributions to climate change, and gives outcomes …

… emissions alone will not abate climate change. At present non-CO 2 greenhouse gases
contribute about a third of total anthropogenic CO 2 equivalent (CO 2 e) emissions and 35–45%
of climate forcing (the change in radiant energy retained by Earth owing to emissions of long-…

… derived Essential Climate Variables (ECVs) in line with GCOS (Global Climate Observing …
Greenhouse Gases” (ECV GHG) is the global distribution of important climate relevant gases
– atmospheric CO 2 and CH 4 – with a quality sufficient to obtain information on regional CO 2 …

… the global climate through radiative forcing, our results identify two indirect mechanisms through
which rising atmospheric CO 2 amplifies climate change: … Future assessments of terrestrial
feedbacks to climate change should therefore consider these indirect effects of increased …
