The phase relations among atmospheric CO2 content, temperature and global ice volume over the past 420 ka

Quaternary Science Reviews 20 (2001) 583}589 Manfred Mudelsee Institute of Meteorology, University of Leipzig, Stephanstr. 3, D-04103 Leipzig, Germany Abstract The phase relations (leads/lags) among atmospheric CO2 content, temperature and global ice volume are key to understanding the causes of glacial-interglacial (G-IG) climate transitions. Comparing the CO2​ record with other proxy variables from the Vostok …

The Relationship between Atmospheric Carbon Dioxide Concentration and Global Temperature for the Last 425 Million Years

MDPI climate W. Jackson Davis Received: 8 August 2017 / Revised: 15 September 2017 / Accepted: 22 September 2017 / Published: 29 September 2017 Abstract Assessing human impacts on climate and biodiversity requires an understanding of the relationship between the concentration of carbon dioxide (CO2) in the Earth’s atmosphere and global temperature (T). Here I …

Univariate statistical analysis of environmental (compositional) data:Problems and possibilities

Peter Filzmoser, Karel Hron, Clemens Reimann Received 8 May 2009 Received in revised form 24 July 2009 Accepted 5 August 200 abstract For almost 30 years it has been known that compositional (closed) data have special geometrical properties.In environmental sciences, where the concentration of chemical elements in different sample materials isinvestigated, almost all datasets are …

Has global warming already arrived?

Elsevier Journal of Atmospheric and Solar-Terrestrial Physics Volume 182, January 2019, Pages 31-38 C.A.Varotsos, M.N.Efstathiou https://doi.org/10.1016/j.jastp.2018.10.020 Highlights The global warming during 1978–2018 was not more enhanced at high latitudes near the surface. The intrinsic properties of the lower stratospheric temperature are not related to those in the troposphere. The results obtained do not reveal the …
