15 May 2017, Climate Home, Bangladesh faces food supply crunch after flash floods. The price of rice has spiked in Bangladesh after flash floods wiped out vast stretches of paddy field just ahead of harvest time. Unusually heavy pre-monsoon rainfall submerged 400,000 hectares of wetland in the northeast of the country, damaging some 2 million tonnes of rice. It is already having an impact on the market. Agricultural economist Quazi Shahabuddin, former head of the Bangladesh Institute of Development Studies, told Climate Home it will cause suffering across the country this year. A kilogram of coarse rice costs 38 Bangladeshi taka ($0.57), a 58% hike since the same period in 2016, according to official data. The government is planning to procure 600,000 tonnes of rice from countries including India and Thailand, the first time in six years it has relied on international markets. The food department has put out a tender for the first 100,000-tonne tranche. “The sudden flash flood has forced us to do that,” explained Badrul Hasan, director general of the food department. The affected districts Netrokona, Sunamganj, Brahmanbaria, Moulovibazar, Hobignaj, Kishoreganj and Sylhet are located at the foothills of Indian Meghalaya and Assam states. Known as “haor” or wetland, this region is typically inundated every year in mid-May and stays underwater for six months. The problem this year was not the volume of rain, but the timing. Flash floods came at the end of March, before the farmers had harvested the “boro” crop they rely on for their annual income. Read More here

6 May 2017, Inside Climate News, Extreme Weather Flooding the Midwest Looks a Lot Like Climate Change. Devastating storms still roiling much of the American Midwest have dumped record levels of rain over the past week and caused flash flooding that has killed at least 10 people, inundated towns and highways, and forced hundreds of people to evacuate their homes. Parts of Missouri, Illinois, Indiana, Arkansas and Louisiana received 10 to 15 inches of rain in the past seven days, according to the National Weather Service, resulting in record crests of numerous rivers across the central United States.Extreme storms like these have become more common as global temperatures have risen and the oceans have warmed. Some have the clear fingerprints of man-made climate change. “Of course there is a climate change connection, because the oceans and sea surface temperatures are higher now because of climate change, and in general that adds 5 to 10 percent to the precipitation,” Kevin Trenberth, a climate scientist with the National Center for Atmospheric Research, said. “There have been many so-called 500-year floods along the Mississippi about every five to 10 years since 1993.” Scientists won’t know the extent to which climate change played a role in these storms unless they do an attribution study. Such analyses determine how much the rise in trapped greenhouse gases increased the odds of a single event happening. Increasingly, scientists have tried to do these studies far more quickly to spread accurate information about how climate change is affecting us today and improve longer-term forecasts and warnings. An attribution study of last August’s deadly Louisiana’s storms—classified as a 1,000-year storm in the worst-hit areas and a 500-year storm in others—found that human-caused climate warming increased the chances of the torrential rains by at least 40 percent. That figure corresponds to the overall increase in extreme storms in the region. “Across the board, the United States has seen an increase in the heaviest rainfall events, and the Midwest specifically has seen an increase [in these events] of almost 40 percent,” said Heidi Cullen, chief scientist at Climate Central and a member of World Weather Attribution (WWA), a group that is developing methods to quickly determine climate change’s role in extreme weather events.

5 May 2017, Bloomberg Business Week, The Jersey Shore Would Rather Fight Flooding With Walls Than Retreat. The state’s $300 million fund to get coastal homeowners to relocate inland isn’t working. n a recent rainy afternoon near the Jersey Shore, John Spodofora, the mayor of Stafford Township, stood at the edge of the water and pointed to a spot in the salt marsh where he wants to build a giant berm to blunt the force of hurricanes. Stafford is on the western side of Barnegat Bay, the 40-mile body of brackish water north of Atlantic City that’s surrounded by blue-collar bungalows, cheap motels, and oceanfront mansions. In 2012, Stafford took a direct hit from Hurricane Sandy, which destroyed 3,000 of its homes. Rather than leave, most residents chose to rebuild. The berm project would cost as much as $100 million, money the town doesn’t have. Spodofora is hoping the federal or state government will fund it, even though most of the 5,000 homes the berm would protect will likely be underwater in a few decades with or without it. Still, Spodofora is committed. “There’s no areas of my town that I can say aren’t worth protecting,” he says. In coastal New Jersey, the debate about whether the climate is changing has been superseded by a more urgent question: What to do about it? While local officials such as Spodofora want to build walls against rising seas and fiercer storms, environmentalists say that delays the inevitable. The best policy, they say, is to encourage people to move inland and let the most vulnerable areas disappear into the water. They may have found allies in the Federal Emergency Management Agency. After spending more than $278 billion on disaster relief over the past decade, the agency has begun to consider a change in tactics. In March, Bob Fenton, FEMA’s acting administrator, told a meeting of state emergency directors that governments need to find ways to reduce risk. “We need to move out of threatened areas,” he said. New Jersey shows just how hard that will be. Read More here
28 April 2017, Climate News Network, Sea floor erosion causes coral reefs to sink. Five US coral reefs are sinking beneath the waves due to the erosion of the sea floor, robbing coastal communities of their natural storm barrier. The world’s coral reefs are not just in hot water and under threat from acid attack; they may even be getting out of their depth. New research around five US coral reefs shows that even as sea levels rise, the sea floor around the reefs is being eroded. And coral growth simply may not be fast enough to keep up, which means that coastal communities in Florida, the Caribbean and Hawaii could become increasingly at risk from storms, waves and erosion. The news comes close after revelations that great tracts of Australia’s Great Barrier Reef, like other coral colonies, have been devastated by bleaching, as ocean temperatures rise above the levels that corals – animals that live in symbiosis with algae – can tolerate, and researchers have warned that this could soon be happening to reefs almost everywhere, every year. Coral under threat There is already widespread alarm among marine scientists as the seas become measurably more acidic due to an increase in levels of carbon dioxide in the atmosphere, and this too poses a threat to corals everywhere. But while researchers in the tropics had monitored the living reefs of the surface waters, hardly anybody had paid attention to the sea floor around the reefs. Now, scientists of the US Geological Survey report in Biogeosciences that – possibly as a consequence of the degradation of the reefs of the Florida Keys, the US Virgin Islands and the Hawaiian island of Maui – the sea floor is being scoured of sand and sediments, just as sea levels continue to creep to a predicted rise of up to a metre by 2100.
