[1] The Indian summer monsoon shapes the livelihood of a large share of the world’s population. About 80% of annual precipitation over India occurs during the monsoon season from June through September. Next to its seasonal mean rainfall, the day-to-day variability is crucial for the risk of flooding, national water supply, and agricultural productivity. Here we show that the latest ensemble of...
Within the time frame of the longevity of tree species, climate change will change faster than the ability of natural tree migration. Migration lags may result in reduced productivity and reduced diversity in forests under current management and climate change. We evaluated the efficacy of planting climate-suitable tree species (CSP), those tree species with current or historic distributions im...
Aspalathus linearis (Burm. f.) R. Dahlgren (rooibos) is endemic to the Fynbos Biome of South Africa, which is an internationally recognized biodiversity hot spot. Rooibos is both an invaluable wild resource and commercially cultivated crop in suitable areas. Climate change predictions for the region indicate a significant warming scenario coupled with a decline in winter rainfall. First estimat...
Future stratospheric ozone concentrations will be determined both by changes in the concentration of ozone depleting substances (ODSs) and by changes in stratospheric and tropospheric climate, including those caused by changes in anthropogenic greenhouse gases (GHGs). Since future economic development pathways and resultant emissions of GHGs are uncertain, anthropogenic climate change could be ...
THE overwhelming majority of climate scientists hold that humanity is facing the prospect of severe climate change and the Assessment Reports of the Intergovernmental Panel on Climate Change (IPCC) contain some stark warnings. In the IPCC’s Fourth Assessment Report, the ‘best estimate’ of the increase in global mean temperatures in the period between 1980–1999 and 2080–2099 ranged from 1.8°C (B...
BACKGROUND Oligoryzomys longicaudatus (colilargo) is the rodent responsible for hantavirus pulmonary syndrome (HPS) in Argentine Patagonia. In past decades (1967-1998), trends of precipitation reduction and surface air temperature increase have been observed in western Patagonia. We explore how the potential distribution of the hantavirus reservoir would change under different climate change sc...
اثر تغییر اقلیم بر روی کشاورزی و امنیت غذائی مردم یکی از مهمترین موضوعات مطرح در سطح جهان است. استان تهران با داشتن 60125 هکتار سطح زیرکشت گندم (سال زراعی 1389-1388) و عملکرد تولید 6/3795 تن در همین سال دارای بیشترین عملکرد تولید در بین استانهای کشور بوده است. هدف از این مطالعه ارزیابی اثر تغییر اقلیم بر عملکرد تولید محصول گندم در استان تهران است. دادههای هواشناسی 58 سال (2009-1951 میلادی) ...
The aim of the study is to analyze and discuss possible climate change impacts on flood damages in Germany. The study was initiated and supported by the German insurance sector whereby the main goal was to identify general climate-related trends in flood hazard and damages and to explore sensitivity of results to climate scenario uncertainty. The study makes use of climate scenarios regionalize...
