[1] Carbon (C) in tropical peatlands over Southeast Asia and Amazonia, if released to the atmosphere, can substantially increase the growth rate of atmospheric carbon dioxide. Over Southeast Asia, where the most extensive tropical peatlands in the world occur, 11 climate models for the IPCC Fourth Assessment show an overall decrease of rainfall in future dry seasons. Over Amazonia, future rainf...

[1] Historical observations indicate a shift toward shorter winters and increased average air temperatures in the midwestern United States. Furthermore, a rise in soil temperatures is likely to be enhanced under projections of increased air temperature; however, reduced snow cover during winter may lead to colder soil temperatures in the future. Cumulatively, these changes will affect cold seas...

The first agricultural societies were established around 10 ka BP and had spread across much of Europe and southern Asia by 5.5 ka BP with resultant anthropogenic deforestation for crop and pasture land. Various studies (e.g. Joos et al., 2004; Kaplan et al., 2011; Mitchell et al., 2013) have attempted to assess the biogeochemical implications for Holocene climate in terms of increased carbon d...

drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...

Extended Abstract The study La Economía del Cambio Climático en Chile (Economy of Climate Change in Chile) (CEPAL, 2009) shows the impacts of Climate Change in Chile using the results from the GCM model HadCM3, with two GHG scenarios (A2 and B2). As projected in these scenarios, for the near future period it is expected a raise in temperature in Central and South Chile in the order of 1-2°C and...

The grounded ice in the Totten and Dalton glaciers is an essential component of the buttressing for the marine-based Aurora basin, and hence their stability is important to the future rate of mass loss from East Antarctica. Totten and Vanderford glaciers are joined by a deep east-west running subglacial trench between the continental ice sheet and Law Dome, while a shallower trench links the To...

Projections of future climate are determined by a wide array of detailed and imperfectly understood physical processes. While ensembles of global climate model (GCM) simulations can be run to sample the resulting uncertainties, statistical tools are needed to supplement these simulations, and hence provide a more comprehensive picture of how interactions between different processes influence th...

امروزه این باور وجود دارد که فعالیتهای انسانی، از جمله تغییر در پوشش و کاربری اراضی، موجب افزایش غلظت گاز های گلخانه ای می گردد، که پیامد آن برهم خوردن توازن کارمایه، گرم شدن اتمسفر، و در نهایت پدیده­ی تغییر اقلیم می باشد. پیش بینی بارندگی یکی از مهمترین مسائل در برنامه ریزی و مدیریت منابع آب می باشد. در این پژوهش، اندازه­ی بارندگی ایستگاههای کرمان، راور و رابر با استفاده از خروجیهای شبیهhadcm3...
