Canada emissions of greenhouse gases (CO2, CH4, N2O) 1990 and 2010 projections Canada emissions of greenhouse gases (CO2, CH4, N2O) 1990 and 2010 projections
Emissions from human activities, and primarily fossil fuels, contribute to climate change, global warming and the greenhouse effect. This is primarily from industry, energy, transportation and related sectors. Please note that this collection of graphics has since been updated, please see http://www.grida.no or http://unfccc.int/ for the latest information and graphics

Example of enhanced water levels produced from river ice, Liard River, Canada Example of enhanced water levels produced from river ice, Liard River, Canada
The lower curve shows the correspondence between river flow and water levels under open-water conditions. The much greater maximum water levels possible under ice-jam conditions are illustrated by the upper curve. The transition in break-up severity from dynamic to thermal break-up effects (see text) is depicted by the gradually shaded area between the two curves. Dots are observed annual maximum water levels during the spring break up. The 1990...

Arctic delta pond ecosystems, seasonal flooding and adaptation Arctic delta pond ecosystems, seasonal flooding and adaptation
The physical development and ecosystem health of river deltas in cold regions are strongly controlled by ice processes and thus are highly susceptible to the effects of climate change. As an example, the photograph shows a typical lake/pond and river network in the Peace-Athabasca Delta (Canada), one of the largest freshwater deltas in the world. The water budget and sediment-nutrient supply for the multitude of lakes and ponds that dot the ripar...

Trends in spring temperatures and ice break-up dates in Canada Trends in spring temperatures and ice break-up dates in Canada
In Canada, recent evidence indicates a shortening of the freshwater-ice season over much of the country with the reduction being mainly attributable to earlier break ups. These trends match those in surface air temperature during the last 50 years. For example, similar spatial and temporal patterns have been found between trends (1966 to 1995) in autumn and spring 0°C isotherms (lines on a map showing location of 0°C air temperatures) and lake fr...

Canada, greenhouse gas emissions (COP7) Canada, greenhouse gas emissions (COP7)
This set of graphics has been produced by GRID-Arendal in co-operation with the secretariat of the United Nations Framework Convention on Climate Change (UNFCCC) for the 7th Conference of the Parties (COP-7) to the Convention, held in Marrakesh, Morocco 29th October to 9th November 2001. This graphic shows total greenhouse gas emissions from Canada. Please note that this graphic is outdated, and has since been replaced with more updated informa...

Canada, Arctic indigenous population Canada, Arctic indigenous population
Depending on the definition of the boundaries of the region, the Arctic is home to some 4 million inhabitants. Roughly one-third of this total population is indigenous peoples, spread over numerous communities around the Arctic. The indigenous proportion of each polar region varies significantly- from 88% of the regional population in Nunavut Territory in Canada (the Inuit), to 2.5% in the North of Scandanavia and the Kola Peninsulathat (the Saam...
