The high capacity of the agricultural sector in Kermanshah Province needs more attention for some reasons including weather and climate conditions, access to fertile lands, and ready-made labor force. The current research seeks to achieve a major strategy for the development of entrepreneurship activities in the agricultural sector of Kermanshah Province. To reach end a mixed research method wa...

Using the Max Planck Institute for Meteorology Earth System Model, we investigate the forcing of forests and the feedback triggered by forests in the pre-industrial climate and in the early Eocene climate (about 54 to 52 million years ago). Other than the interglacial, pre-industrial climate, the early Eocene climate was characterised by high 5 temperatures which led to almost ice-free poles. W...

Maps of interpolated climate normals have recently become essential tools for many types of forestry research, such as studying genetic adaptation of trees to local environments, modeling species ranges shifts, or forest productivity under climate change scenarios. In this paper, we evaluate two widely used climate models for British Columbia with respect to their general precision and regional...

climate change which is derived by increase of atmospheric co2 concentration and other greenhouse gases could have considerable effects on productivity of crops in the future. climate change impacts on chickpea yield were investigated and yield maps of dryland areas of zanjan province were provided. investigated scenarios were control scenario, in which simulated current situation, and climate ...

E very year, the Bulletin of the AMS publishes an annual report on the State of the Climate [e.g., see the Blunden and Arndt (2012) supplement to this issue]. That report does an excellent job of documenting global weather and climate conditions of the previous year and putting them into accurate historical perspective. But it does not address the causes. One of the reasons is that the scientis...
