Average temperature in Oslo
Yearly average temperatures in Oslo (capital of Norway) 1850-1995 as deviation from normal temperature 1961-1990. Source: The Norwegian Meteorological Institute.
The yearly average temperature in Oslo does not indicate any climate change.
A climate change does not necessarily imply warmer weather everywhere in the long run. Norway might experience other climate changes like more precipitation, more extreme weather conditions and even a colder climate due to possible changes in the Gulf stream and other ocean currents.
Unfortunately, no finalised standards for measuring changes in occurrences of extreme weather conditions exists for the time being.
Global average temperature
Global average temperature as deviation from average temperature 1961-1990, and as sliding 10 year average. Sources: Hanson/Lebedeff (update) and IPCC. See also IPCC's predictions for year 2100 and Climatic Research Unit, University of East Anglia.
It is difficult to find reliable indicators for climate change, as natural fluctuations are considerable. However, the IPCC conference in Rome 1995 concludes that there are now clear signs of man-made climate changes. There are still considerable uncertainties. This is expressed through a high and a low estimate of what the average global temperature will be in a hundred years from now. The likely average temperature will be somewhere in between these two estimates.
Expected consequences of increased greenhouse effect are:
- Gradual global warming
- Climatic changes, with impacts on wind patterns and precipitation. Some areas are expected to receive more rain while other areas will become drier.
- Rising sea level
- Changing ecosystems and production patterns
