Northern Hemisphere controls on tropical Southeast African climate during the past 60,000 years
The processes that control climate in the tropics are poorly understood. We applied compound-specific hydrogen isotopes (D) and the TEX86 (tetraether index of 86 carbon atoms) temperature proxy to sediment cores from Lake Tanganyika to independently reconstruct precipitation and temperature variations during the past 60,000 years.

22% less rainfall in Kerala
THIRUVANANTHAPURAM: The 2008 edition of the South-West monsoon was weak over Kerala with 22 percent less rainfall than normal. The State received only 168 cm of rain from June to September, against the normal 214 cm, the Indian Meteorological Department (IMD) said.

NASA data show some African drought linked to warmer Indian Ocean
A new study, co-funded by NASA, has identified a link between a warming Indian Ocean and less rainfall in eastern and southern Africa. Computer models and observations show a decline in rainfall, with implications for the region

Crop yield response to climate change in East Africa: Comparing highlands and lowlands
Climate change will have significant impacts on agriculture, particularly in East Africa where there is such variation in topography and climate. Modelling studies can help to show where these impacts may be largest, to help guide adaptations to ensure food security in the coming decades. Results suggest that crop yield reductions may be expected over 50% to 70% of the area simulated.

Dimensions of global change in African mountains: The example of Mount Kenya
This paper discusses the effects of global change in African mountains, with the example of Mount Kenya. The geographical focus is the northwestern, semi-arid foot zone of the mountain (Laikipia District). Over the past 50 years, this area has experienced rapid and profound transformation, the respective processes of which are all linked to global change.

Satellite rainfall estimation in the Hindu Kush-himalayan region
Satellite-enhanced rainfall estimation appears to offer an effective and viable alternative means for estimating precipitation. Satellite-improved rainfall estimates for the HKH region delivered in a timely fashion will facilitate the use of regional flood-information systems.

Analysis of variability and trends of extreme rainfall events over India using 104 years of gridded daily rainfall data
In this study, using 104 years (1901–2004) of high resolution daily gridded rainfall data, variability and long-term trends of extreme rainfall events over central India have been examined. Frequency of extreme rainfall events shows significant inter-annual and inter-decadal variations in addition to a statistically significant long term trend of 6% per decade. Detailed analysis shows that inter-annual, inter-decadal and long-term trends of extreme rainfall events are modulated by the SST variations over the tropical Indian Ocean. The present study supports the hypothesis that the increasing trend of extreme rainfall events in the last five decades could be associated with the increasing trend of sea surface temperatures and surface latent heat flux over the tropical Indian Ocean. In the global warming scenario, the coherent relationship between Indian Ocean SST and extreme rainfall events suggests an increase in the risk of major floods over central India.

Governor concerned over global warming effect
Meghalaya, despite its low population density and little industrialization, contributes least to global warming, but could become one of the worst sufferer of the impending climate change, Governor RS
