The fourth assessment report of the intergovernmental panel on climate change: Working group II contribution

Abstract

Basic results of IPCC Working Group II, derived in the process of the work at the Fourth Assessment Report, are considered in brief. The results are given in conformity with the Summary for Policymakers adopted at the Plenary Meeting of Working Group II in Brussels on April 6, 2007. The authors' comments on some results connected with the key vulnerable elements of natural and socioeconomic systems are given in the conclusion.Key impacts: Dependence on increasing global mean air temperature (they also depend on adaptation, rate of temperature change, the way of socioeconomic development). Two asterisks denote high reliability impacts. Changes in global mean temperature are given relative to the level of 1980-1999. "Significant" means > 40%. An asterisk denotes the impact based on the assessment of the rate of the sea level rise of 4.2 mm/year in 2000-2080.

Ecophysiological model of net primary production of woody species and estimation of their climatic ranges

“…There is a vast body of literature devoted to formalization of assimilation and stomatal conductance dependence on each of these factors. We selected the corresponding functions in the simplest and widely used form found in the literature [4,19].…”

“…These consequences may relate, in particular, to natural systems, economy, and human health [4,9,44]. The consequences may have different scales: global, regional, and even local.…”

The correlation between precipitation and temperature of cold and posterior warm periods in the South of Khabarovsk Krai

“…Previous investigations carried out after [1] for the territory of the south of Khabarovsk krai for the period of 1979-2008 demonstrated that during recent 30 years, the average annual air temperature has been increasing here by 0.09°per year, mainly in the cold period (November-March) [2]. The total precipitation during the warm period in the south of Khabarovsk krai decreases by 65 mm per year on average whereas the sum of monthly mean temperature values of the warm period and total precipitation of the cold period remain invariable.…”

Effect of regional climate variations and economic activity on changes in the hydrological regime of watersheds and small-river runoff

“…Kondrat'ev [30], V.M. Kotly akov [33,34,35], and other researchers [42], as well as reports of the Intergovernmental Panel on Climate Change (IPCC) [22]. Global climate changes cause inevitable changes in the natural course of many natu ral processes and changes in all components of the biosphere at the global, regional, and local levels [16].…”
