Mathematical description of deviation mechanisms positions of track chassis in motion with variable ground resistance by Goncharov K.A.

Chemical Weathering and Erosional Response of Northern New Guinea to Orbital‐Scale Climate Variability by Yifan Du, Peter D. Clift, Andrew Carter

“…Comparing the bulk sediment and source rock compositions shows long‐term variability in the consumption rates of CO2. Weathering is most effective at removing atmospheric CO2 during glacial times when ΔCO2 values (mol/kg) reach around three times those seen in major mainland Asian river systems. …”

Optimising Interannual Sea Ice Thickness Variability Retrieved From CryoSat‐2 by Carmen Nab, Robbie Mallett, Connor Nelson, Julienne Stroeve, Michel Tsamados

“…We derive sea ice thickness from CryoSat‐2 radar freeboard data with incremental values for α, for the 2010–2021 winter periods. By comparing these to sea ice thickness estimates derived from upward‐looking sonar moorings, we find that α values between 35%–80% result in the best representation of interannual variability observed over first‐year ice, reduced to <55% over multi‐year ice. …”

More positive and less variable North Atlantic Oscillation at high CO2 forcing by Ivan Mitevski, Simon H. Lee, Gabriel Vecchi, Clara Orbe, Lorenzo M. Polvani

“…While Earth System Models generally project a more positive NAO under 21st century high-emission scenarios, uncertainties persist as to the precise response of the NAO to increased CO2 levels, owing to large internal variability. In this study we investigate the response of the NAO to a wide range of CO2 forcings, from two to eight times the preindustrial values. …”
