Climate Change 2021—The Physical Science Basis
The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body responsible for assessing the science related to climate change. The Sixth Report from IPCC Working Group 1 published…

Mid- to Late Holocene climate change: an overview
Atmospheric CO2 concentrations over the last glacial termination.
The similarity of changes in CO2 concentration and variations of atmospheric methane concentration suggests that processes in the tropics and in the Northern Hemisphere, where the main sources for methane are located, also had substantial effects on atmospheric CO2 concentrations.
High-resolution carbon dioxide concentration record 650,000–800,000 years before present
It is found 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, which extends the pre-industrial range of carbon dioxide concentrations during the late Quaternary by about 10 p.p.m.v.
Orbital and Millennial Antarctic Climate Variability over the Past 800,000 Years
It is suggested that the interplay between obliquity and precession accounts for the variable intensity of interglacial periods in ice core records.
Holocene carbon-cycle dynamics based on CO2 trapped in ice at Taylor Dome, Antarctica
A high-resolution ice-core record of atmospheric CO2 concentration over the Holocene epoch shows that the global carbon cycle has not been in steady state during the past 11,000 years. Analysis of…
Orbital and millennial-scale features of atmospheric CH4 over the past 800,000 years
It is suggested that changes in the strength of tropical methane sources and sinks (wetlands, atmospheric oxidation) controlled the atmospheric methane budget, with an additional source input during major terminations as the retreat of the northern ice sheet allowed higher methane emissions from extending periglacial wetlands.
An improved method for detecting anthropogenic CO2 in the oceans
An improved method has been developed for the separation of the anthropogenic CO 2 from the large natural background variability of dissolved inorganic carbon (C) in the ocean. This technique employs…
