Climate change communication and adaptation



Farmers and pastoralists, as well as policy makers, development and humanitarian programmes in Africa are searching for the best ways to adapt to the impacts of climate variability and change. Changes in seasonal rainfall patterns and more unpredictable, severe and frequent extreme events like floods and droughts are already being observed, threatening livelihoods in vulnerable communities.
Most adaptation strategies aim to spread or reduce potential risks, for example by using drought tolerant seeds, cereal banks, diversification to non climate dependent income sources, weather based insurance products, or early warning systems. Although such concrete measures are essential, climate change is continuous and unpredictable. Adaptive capacity to make informed and flexible decisions for action is becoming even more important to ensure resilience to climate change impacts.
Climate science and meteorology provide valuable sources of information that can help, not only in predicting future weather and climate (which can never be fully accurate), but also in developing understanding and skill in befriending and managing uncertainty. Seasonal forecasts for example, give probabilities of three different rainfall scenarios.

Gene cloned proteins yet to live up to the Hype...



There’s no argument that biotechnology has dramatically improved global healthcare with the introduction of many novel biotherapeutics . A few examplies include:
Enbrel for the treatment of rheumatoid arthritis; 
Rituxan for non-Hodgkin’s lymphoma; Herceptin for breast cancer; 
Humulin for diabetes; Procrit for the treatment of anemia in patients with kidney failure, HIV, or cancer
Avastin for metastatic colorectal cancer, advanced nonsquamous non–small cell lung cancer, metastatic kidney cancer, and glioblastoma.
