This page contains a description of causes and effects of what is commonly referred to as climate using the Pyrkilo method. The data used in this assessment is composed of 10 climate change related articles by 10 invited experts published in Helsingin Sanomat during Summer 2006.

'''Climate change''' typically refers to the global change of climatic patterns due to human activities, notably the release of carbon dioxide and other greenhouse gases. For more description, see [[:Category:Climate change]] or [[:en:Climate change|Climate change]] in [[Wikipedia]].
  
The description currently only includes the causes of climate.
+
The text from a [http://en.opasnet.org/en-opwiki/index.php?title=Climate_change&oldid=12136 previous version] was moved to [[Dependencies of climate change]].
The effects side of the description will be added later.

Climate change typically refers to the global change of climatic patterns due to human activities, notably the release of carbon dioxide and other greenhouse gases. For more description, see Category:Climate change or Climate change in Wikipedia.

The text from a previous version was moved to Dependencies of climate change.
