The A., a physical geographer, addresses climate change and feedbacks for Eurasia over longer (tectonic forcing, intermediate (Earth's orbital relations) and shorter timeframes, emphasizing that climates change more or less continuously in response
to many forcing factors (solar output, Earth's eccentric orbit, rotational tilt, precession, and interactive atmosphere-ocean-land systems, including human impacts). The nesting of the current, three-decade pattern of warming within longer centennial
- and millennial-scale cycles of warming and cooling since the Holocene Optimum, shows that the recent rapid warming since 1980 is not unique in Earth history, although it does warrant concern and raises questions of global significance.
Permafrost mapping of Northeast European Russia based on the period of climaticwarming 1970-1995

The geographic information system (GIS) Permafrost of the Usa River Basin was developed based on data for permafrost distribution and temperatures obtained for the period of recent warming (1970-1995). In this paper, the AA. describe the main stages
The understanding of North Atlantic climate and the dual processes of global warming and Gulf Stream action which affect it, is as uncertain today as in the early 2000s. This paper will show how fast our ideas on future global and North Atlantic
climate are altering. The interaction of positive and negative feedbacks are key to our future climate. The impact of the thermohaline circulation and of the wind power and stronger westerlies are discussed. The worrying projections on future climate

Model simulations and paleoclimatic data studies show an evident change in temperature and precipitation over China will occur under conditions of the global warming. Possible scenarios of the future climates are given here for China on the basis
of synthesizing model simulations and paleoclimatic data. Most parts of China will experience an increase in temperature, but the warming may be more remarkable in winter in the northern half of the country. Some regions will benefit from the climate change
Possible effects of climatic change on the evolution of Alpine permafrost

The purpose of this paper is to briefly summarize the present-day knowledge about the characteristics of Alpine permafrost, to hint at some first signs of permafrost response to 20th century warming in the Alps, to roughly sketch possible effects
of anticipated warming trends and to outline priorities concerning future research and monitoring activities.
Back to the future : biogeographical responses to climate change
Bibliography ; Biogeography ; Climatic variation ; Climaticwarming ; Global change ; Impact ; Methodology ; Model ; Palaeobiogeography
An appreciation of the degree of global climaticwarming over the past century has led to speculation concerning possible impacts on species, communities, ecosystems and overall global biodiversity. Paleobiogeography, in particular, has been called
upon to provide a key to the future. Back to the future has become a working methodology. But with global warming now quite well advanced, it is now possible to observe its actual biogeographic outcomes.
as the Holocene. There are also many unknowns about abrupt climate shifts in the future when the world will be much warmer than today. One favourite climate scenario suggests that cooling by a shut-down of the Gulf Stream at the end of the present century is more
than likely to be balanced by global warming. In the final analysis, we cannot be certain about our future climate.
This article shows that there are many instances of abrupt climate change in the past, especially during the last ice age, but there is much less evidence of even rapid climate change occurring during the last 10,000 years or so in the period known

to examine the nature and extent of a possible climatic variation. The analysis based on a smaller period climatic data shows a good deal of agreement with the trends of studies on global warming projections made by simulated models on the basis of CO2
Conventional climatic indicators such as rainfall distribution, temperature regime, relative humidity, sunshine duration, wind velocity and evaporation characteristics were examined over a period of twenty six years of available meteorological data
Predicted effects of climatewarming on the commercial culture of the Channel catfish, Ictalurus punctatus
permits the prediction of changes of this distribution resulting from climatewarming.
The AA. review the thermal requirements for growth in catfish and examine the role that climate (air temperature and precipitation) plays in limiting the distribution of profitable fish farms. A model is constructed from these relationships which

A study on environmental aridity over northern and southern to Qinling Mountains under climatewarming

Based on the data up to 1999 from hydroclimatological departments, this paper analyzes the climatic divide implications of the Qinling Mountains in regional response to the process of climatewarming, due to which the grades of dryness/wetness (GDW
) in 100 years show that the northern region has entered a drought period, while the southern is a humid period. This study shows the obvious trend of environmental aridity, which is of help to the understanding of regional response to global climate change.
