Forum GRF Davos is calling for people to submit articles, study, abstracts for presentation at the Forum “5th International Disaster and Risk Conference Integrative Risk Management – The role of Science, Technology & Practice” GRF Davos Davos in Switzerland from 24-28/08/2014.

Forum GRF is a forum of global disaster risk.

Năm 2013 được gọi là Mùa bão Thái Bình Dương, là một sự kiện mà theo đó các xoáy thuận nhiệt đới hình thành ở phía tây của Thái Bình Dương. Mùa bão sẽ kéo dài trong suốt năm 2013 với phần lớn các cơn bão hình thành từ tháng 5 đến tháng 11. Dưới đây là 10 cơn bão đã xuất hiện tại Việt Nam kể từ đầu năm 2013 đến nay.

Bão lớn Sonamu (Bão số 1) 

Ngày 1 tháng Một, 2013, Cơ quan khí tượng Nhật Bản (JMA) bắt đầu theo dõi một áp thấp nhiệt đới phát triển tại vị trí cách Hagåtña, Guam 1085 km về phía Tây Nam. Trong hai ngày tiếp theo vùng thấp di chuyển về phía Tây Bắc, trước khi vượt qua đảo Mindanao, Philippine và cuối ngày mùng 2 tháng Một. Trong ngày 3 tháng Một vùng thấp này di chuyển vào Biển Sulu, và được Cục quản lý Thiên văn, Địa vật lý và Khí quyển Philippines (PAGASA) đặt tên Auring, trước khi cơ quan khí tượng Nhật Bản đưa ra thông báo vùng thấp đã phát triển trở thành bão nhiệt đới và đặt tên cho nó là Sonamu.

Earthquakes can contribute to global warming by releasing greenhouse gases from the ocean floor. This finding suggests a natural source of greenhouse gases not previously considered. Research published in the journal Nature Geoscience, News reported.

Scientists have found evidence of a major earthquake in 1945 Arab north sea, emissions than 7 million m3 of methane (CH4) into the atmosphere. This finding suggests a natural source of greenhouse gases not previously considered. Research published in the journal Nature Geoscience,AccordingNewsreported.

But with little in the atmosphere, but CH4 is a greenhouse gas causing higher 20 times higher than CO2. Large amount of CH4 are stored in hydrate ice structure on the floor of the continental shelf around the earth.

Estimated 1.000 to 5.000 giga tonnes of carbon were stored in methane hydrate ice structure, more than the total annual emissions by burning fossil fuels.

After analyzing sediment samples taken from five Arab north sea 2007, group of scientists found signs of a chemical release for large-scale CH4, Historical documents record an earthquake intensity 8,1 magnitude happened nearby in 1945.

Dr. David Fischer from the University of Bremen, Germany says: “Based on a number of criteria, we see that the earthquake ruptured sediments, liberate gas trapped beneath”.

Currently methane hydrate was proposed as a promising energy source, but they are very expensive to exploit and dangers. They are stable on the ocean floor and will be freed if an earthquake, Tsunami.

One study showed that damming a river hydro generating, a drinking water reservoir and recreation, sources are contributing to warming of the earth much earlier than previously thought.

50.000 large dams in the world is a source of methane, spray bubble up from the sediment organic matter after barrier. Methane is a greenhouse gas,, with stronger heating effect of carbon dioxide 25 time.

Andreas Maeck, a graduate student at the University of Koblenz in Germany, team leader methane escaping from the small dam water depth less than 15 meters. There are millions of dams around the world, group and found the relationship between sediment accumulation with the production of methane in water.

Researchers reported that the "hot spots" of methane has the potential to increase the status of this gas to escape 7 %, a higher number of people than previously thought.

In a study published in the journal Environmental Science & Technology, research team warns that gas escapes will certainly increase because of the dam construction booming, by demand for new sources of energy and water shortages.

The Climate Food and Farming (CLIFF) Research Network is a collaborative initiative of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and the Universities of Copenhagen and Aarhus. Each year, starting in 2011, CLIFF has provided small grants to support graduate student research on mitigation of climate change in smallholder agricultural systems.
