	20.01.2010 I.E.FROLOV, Z.M.GUDKOVICH, V.P.KARKLIN, V.M.SMOLYANITSKY CLIMATE CHANGE IN THE ARCTIC AND ANTARCTIC – RESULT OF NATURAL CAUSES Meteorological and ice observations indicate that during the XX century the Earth underwent a process of warming, which during some periods was interrupted by cooling over large areas. The challenge of preventing adverse effects of climate change requires identification of the main causes of this phenomenon. Many climatologists believe that it is caused by the accumulation of greenhouse gases of anthropogenic origin in the atmosphere. However, our recent studies suggest that ongoing climatic changes are a consequence of natural causes. To assess the true mechanisms of climate change, the most important features of this phenomenon are analyzed: the cyclical nature of climate fluctuations, its changes in time and space, relationship with the general circulation of the atmosphere (GCA), as well as incoming total solar radiation. All considered regularities can be explained in the proposed scheme of the natural mechanisms of climate change of decadal and centennial scales. Our projections, based on consideration of natural climate cycles, differ significantly from the results of numerical experiments with climate models. Instead of increasing temperatures and decreasing ice cover in the Arctic, we forecast a drop in temperature towards 2030 – 2040th and increase of ice cover, as well as preservation of the cyclic nature of changes which were characteristic for the XX century. Key words: climate change, Arctic, Antarctic, total solar radiation, solar activity, general circulation of atmosphere, polar vortices.

It is shown that the annual hydrothermal water discharge (2.8-5.5 mt of water per year) is one order of magnitude smaller than the rate of melt water inflow in the northern part of the lake. Key words: Antarctica, Lake Vostok, ice core, hydrological regime, water, balance, isotope composition, air content hydrothermal waters.

	14.04.2010 V.YE.LAGUN, A.V.KLEPIKOV, A.I.DANILOV, A.I.KOROTKOV ON THE WARMING OVER THE ANTARCTIC PENINSULA Analysis of warming process over Antarctic Peninsula due to combined atmosphere-ocean-ice interaction is presented. Remarkable regional warming in the near surface air and in the middle atmosphere is accompanied by cooling of low stratosphere, by dropping of surface pressure and intra-monthly air temperature dispersion, by cloudy cover increasing, by shortening of ice cover period, by thinning of sea ice and changing in the local ecosystems. Possible causes of the warming, connected with large scale circulation of the atmosphere and ocean are considered. Key words: Antarctic Peninsula, climate variability, fast ice, meteorological observations, warming.

	22.03.2010 О.А.ТROSHICHEV PC-INDEX AS AN INDICATOR OF THE SOLAR WIND ENERGY INCOMING INTO THE MAGNETOSPHERE The paper gives a short review of the experimental results, which formed the physical backgrounds for concept of the ground-based index characterizing the solar wind energy input into the magnetosphere. It is shown that the PC index properly responds to influence of the solar wind parameters, such as the geoeffective interplanetary electric field and dynamic pressure pulses, irrespective of UT times, season and location of stations in the northern (PCN) or southern (PCS) hemispheres. Case studies and statistical analyses of relationships between the PC index and magnetospheric substorm and geomagnetic storm clearly demonstrate that the PC growth always preceded to magnetic disturbances, that substorm onset and storm beginning occur when PC value exceeds the define threshold level ~ 2 mV/m, that the intensity and run of substorms is determined by the PC growth rate, that the storm magnitude (Dst min) is proportional to average PC value during growth phase, and so on. These experimental facts testify that the PC index manifests itself as a reliable ground-based indicator of the solar wind energy incoming into the magnetosphere. Keywords: polar cap magnetic activity, magnetospheric substorms, magnetic storms, solar wind energy, magnetosphere state diagnostic.
