Emissions of greenhouse gases in Norway, C2F4 and C2F6 85-96
The graphic shows emissions of C2F4 and C2F6 in CO2 equivalents in Norway from 1985 to 1996. C2F4 and C2F6 are primarily results of the production process of alumunium. Their atmospheric lifetime is estimated to be aroun...

Emissions of N20 in Norway, 85-96
The graph shows emissions of N20 in Norway from 1985 to 1996 with projections to 2010. N20 can occour naturally or have anthropogenic sources such as fertilizrs, combustion and various industrial processes.

Sale of pesticide in Norway
Due to the high latitude and a relatively short growing season in Norway, the number of pests is limited compared with middle and southern Europe. However, some weed species are more dominant due to a general wet and col...

Norwegian emissions of CO2
Emissions of carbon dioxide in Norway, 1985-1997, with projections up to 2010 (with a current measures scenario, as of 1997). Carbon Dioxide (CO2) is the main agent of greenhouse gases that is released primarily from the...

Emissions of SF6 in Norway, 85-96
The graph shows emissions of SF6 in Norway from 1985 to 1996.SF6 is a highly potent greenhouse gas used in the industry for insulation in high voltage equipment and current interruption in electric transmission and distr...

Norwegian emissions of methane (1985-1996)
The graph shows Norwegian emissions of methane from 1985 to 1996. Methane is emitted to the atmosphere by both natural and anthropogenic sources. Among these are fossil fuels, waste dumps, and livestock.

Projected changes in Arctic pack ice (sea ice minimum extent)
The averages of the scenarios in the Arctic Climate Impact Assessment (ACIA) for the Arctic sea ice extent (the permanent ice) are presented in this map, with the successive decrease in the ice up to 2090. The projection...

South America, southern ice fields
In Southern South America there are primarily three ice fields with major glaciers - the Northern and Southern Patagonian Icefield in the Andes, and then Cordillera Darwin in the very south. All of these are very vulnera...

Trends in the ice-breaking date in the Tornio river, Finland
The icebreaking date for the Tornio River in Finland has been recorded since 1693. With the increased greenhouse effect, impacts on the cryosphere are likely. One impact will be less ice on rivers and lakes. Freeze-up da...

Arctic sea routes - Northern sea route and Northwest passage
Sea routes along the edges of the Arctic ocean, or rather along the coasts of Northern Canada and Russia, holds potential for decreasing the number of days in shipping goods from the Pacific to Atlantic coasts in Europe ...

Malaria risk and climate change
Plasmodium vivax, with the Anopheles mosquito as a vector, is an organism causing malaria. The main climate factors that have bearing on the malarial transmission potential of the mosquito population are temperature and ...

Radiative forcing - energy balances and the greenhouse effect
Radiative forcing is the change in the balance between radiation coming into the atmosphere and radiation going out. A positive radiative forcing tends on average to warm the surface of the Earth, and negative forcing te...

Change in permafrost temperature in Fairbanks (Alaska)
With a doubling of atmospheric CO2, it is likely that there will be increases in the thickness of the active layer permafrost and the disappearance of most of the ice-rich discontinous permafrost over a century-long time...

Trends in global temperatures
The figure shows the combined land-surface air and sea surface temperatures (degrees Centigrade) 1861 to 1998, relative to the average temperature between 1961 and 1990. The mean global surface temperature has increased...

Temperature trends and projections
Using the IS92 emission scenarios, projected global mean temperature changes relative to 1990 were calculated up to 2100. Climate models calculate that the global mean surface temperature could rise by about 1 to 4.5 cen...

Scenarios of sea level rise, now - 2100
Using the IS92 emission scenarios, projected global mean sea level increases relative to 1990 were calculated up to 2100. Taking into account the ranges in the estimate of climate sensitivity and ice melt parameters, and...

Sea level rise due, past and scenarios due to global warming
Over the last 100 years, the global sea level has risen by about 10 to 25 cm. Sea level change is difficult to measure. Relative sea level changes have been derived mainly from tide-gauge data. In the conventional tide-g...

CO2 emissions from industry
This map depicts the unequal distribution of industry in the world. The significant part of carbon dioxide emissions comes from energy production, industrial processes and transport. The industrialised countries conseque...
