... published papers and openly available data on sea level changes, glacier retreat, freezing/break-up dates of rivers, sea ice retreat, tree-ring observations, ice cores and changes of the cosmic-ray intensity, from the year 1000 to the present, are studied ...
... the recovery from the LIA has proceeded continuously, roughly in a linear manner, from 1800-1850 to the present.
... the Earth is still in the process of recovery from the LIA; there is no sign to indicate the end of the recovery before 1900.
... The multi-decadal oscillation of a period of 50 to 60 years was superposed on the linear change; it peaked in 1940 and 2000, causing the halting of warming temporarily after 2000.
... These changes are natural changes, and in order to determine the contribution of the manmade greenhouse effect, there is an urgent need to identify them correctly and accurately and re-move them from the present global warming/cooling trend.Sea level data, for example:
