afs-72739	Mela, Timo J. N.	Northern agriculture: constraints and responses to global climate change	1996	6	.pdf	application/pdf	3030	142	58	In North America, fields extend to about 55°N, In Asia, there are few fields north of 60°N. Finland is the most northern agricultural country in the world, with all its field area, about 2.5 million hectares, located north of latitude 60°N. Changes in the climate and atmospheric C0 2 predicted for the future are likely to have a strong influence, either beneficial or disadvantageous, on the conditions for growth in northern areas where the annual mean temperature is 5°C or less. Changes in climate Predicted changes in climate as a result of the increasing content of so-called greenhouse gas- es, carbon dioxide (C02 ), methane (CH4 ), nitrous oxide (N,O), tropospheric ozone (O,) and halo- carbons could have an important influence on the conditions for growth in northern areas.	cache/afs-72739.pdf	txt/afs-72739.txt
