  • Ilmastonmuutos (in Finnish)

  • ---------------------------------------------------------------
  • A brief wiew of the latest data of climate change.

  • ---------------------------------------------------------------
  • What signs are there of the socalled global warming or global cooling in Helsinki in 1829-2008 and two rural places in Finland in 1900-2008? How do they accord to HADCRUT3 or UAH data?

  • *****************************************************************


    The temperature in Helsinki and Sodankylä in Finland in 1972-2008 with a HADCRUT3 and UAH comparison
  • Has the global cooling started? A monthly graph based on HADCRUT3 and UAH data from January 2007 to November 2008.
  • Changes in Helsinki temperature during the period of 1972-2007
  • Graphs about the temperature in Helsinki, the HADCRUT3 temperatures and some UHI-free places during the period of 1972-2007
  • The temperature in Helsinki compared with HADCRUT3, the world temperature, smoothed from 1988-2007 to 1989-2006 to avoid QBO

    The warm 1930's.

  • How does the warm period in 1990's and 2000's compare with the warm period of 1930's?
  • When did the cold period after the 1930's actually begin?
  • The two cold periods in 1940-1942 and 1985-1987 compared
  • ===================================================================

    Graphical comparisons of the cold period of 1950-1978 plus the warm periods surrounding it.

  • The cold period of 1950-1978 divided into three parts plus its relations to the surroundings 1934-1949 and 1988-2005
  • The cold period of 1950-1978 plus its relations to the surroundings with QBO (quasi-biennial oscillation) removed.
  • The warm periods of 1934-1939, 1988-1992 and 1999-2005 compared.
