greenhouse gases
Since industrialization and human activities is advancing the concentration of greenhouse gases in the atmosphere is steadily increasing. As a result of green house gas effect the world’s average surface temperature has increased between 0.3 and 0.6oC over the past hundred years. There is expectation of global average temperature increase by 1.4 to 5.8°C in 2100 with the increase of...
The Earth's ice cover is melting in more places and at higher rates than at any time since record keeping began. Reports from around the world compiled by the Worldwatch Institute show that global ice melting accelerated during the 1990s-which was also the warmest decade on record.
Scientists suspect that the enhanced melting is among the first observable signs of human-induced...
Over the past decade, the issue of climate change has risen rapidly to an important position on international scientific and political agendas. A number of key events in this process may be identified, beginning with the 1988 Conference on "The Changing Atmosphere" (World Meteorological Organization 1989), and the consequent establishment of the Intergovernmental Panel on Climate Change (IPCC...
The possible effects of enhanced greenhouse climate change have been wide debated in the general and scientific community. The current distribution of alpine and high country flora and fauna species, their current predicted climatic envelope determined using BIOCLIM and several scenarios of regional climate change developed by the CSIRO were utilized to develop scenarios for the alpine...
Scotland has over 90 percent of the UK's montane (alpine) habitat. These areas contain important populations of relic arctic, alpine and endemic plants, which also support important bird populations, all of which are of high conservation value. Within these areas, natural zonation of vegetation can be seen at different altitudes. This zonation is largely due the effects of temperature and...
