According to a new technical report, the effects of climate change will continue to threaten the health and vitality of U.S. coastal communities’ social, economic and natural systems.
Blanket bogs, which provide vital habitats for a unique range of plants, birds, small mammals, reptiles and amphibians, are at risk of declining as a result of climate change.
Research by the Universities of Exeter and Bristol in the UK and Macquarie University in Australia, published in the journal Nature Climate Change, shows for the first time how rising temperatures will threaten these sensitive ecosystems.
The study highlights the urgency of developing a plan to protect these important habitats.
Found in wet, coastal areas of high latitude regions, blanket bogs cover around 700,000 hectares of land in the UK, much of it designated as a Site of Special Scientific Interest (SSSI). Blanket bogs are found in the north and west of the UK, extending from Devon in the south to Shetland in the north, and it has been estimated that 10 to15 per cent of the world’s blanket bog occurs in Britain. As well as being crucial in supporting wildlife, blanket bogs also capture and store large amounts of carbon, helping to mitigate against climate change, and reduce the risk of flooding, by slowing down water flow. With some blanket peat being over 9,000 years old, they also hold historically-significant archaeological material. (more…)
Women in rural Bangladesh prefer inexpensive, traditional stoves for cooking over modern ones — despite significant health risks, according to a Yale study in the Proceedings of the National Academy of Sciences.
A large majority of respondents (94%) believed that indoor smoke from the traditional stoves is harmful. Still, Bangladeshi women opted for traditional cookstove technology so they could afford basic needs.
“Non-traditional cookstoves might be more successful if they were designed with features valued more highly by users, such as reducing operating costs even if they might not reduce environmental impact,” said Mushfiq Mobarak, a co-author and associate professor of economics at the Yale School of Management.

New estimates suggest more U.S. land prone to flooding than previously thought.
About 3.7 million Americans are at risk for flooding as the sea level continues to rise in the coming century, according to a new study from a team that includes University of Arizona researchers.
Areas on the south Atlantic Seaboard and surrounding the Gulf of Mexico appear to be most prone to future flooding. In terms of numbers of people at risk, Florida is the most vulnerable, closely followed by Louisiana, California, New York and New Jersey. (more…)
ANN ARBOR, Mich.— Typhoons thrash the Philippines every year, causing flash flooding and mudslides that often kill hundreds of people in the Southeast Asian nation. Many blame the death and destruction on the wrath of nature. But Gavin Shatkin has a different view.
“Disasters are not natural,” said Shatkin, an associate professor of urban planning at the University of Michigan. “They happen because of social structures.” (more…)
History tells us that Paul Chomedey de Maisonneuve erected a cross atop Mount Royal in 1643 to thank God for sparing the city from flooding. However, according to 18th century archival documents, the cross was planted two kilometers away from where it is today.
“I discovered a document reporting the trial of a man accused of murder and living near the cross in 1750,” says Theresa Gabos. “When going through the aveux et dénombrements (the land and assets belonging to an individual) of the time, we learn that this man lived near the current intersection of Sherbrooke Street and chemin de la Côte-des-Neiges. This wasn’t the De Maisonneuve cross, but rather a replica of the original that had rotted. Nonetheless, this probably reveals the original location of the cross and highlights the fact that perception of the mountain and its summit has evolved with time.” (more…)
WASHINGTON —The extreme rain events that have caused flooding across northern Australia may become an increasingly familiar occurrence, new research suggests. The study uses the growth patterns in near-shore corals to determine which summers brought more rain than others, creating a centuries-long rainfall record for northern Australia.
“This reconstruction provides a new insight into rainfall in northeast Queensland,” says Janice Lough, climate scientist of the Australian Institute of Marine Science (AIMS) in Townsville, Queensland, who authored the study. “These coral samples, which date from 1639 to 1981, suggest that the summer of 1973–1974 was the wettest in 300 years. This summer is now being compared with that record-setting one.” (more…)
SACRAMENTO, Calif. — For emergency planning purposes, scientists unveiled a hypothetical California scenario that describes a storm that could produce up to 10 feet of rain, cause extensive flooding (in many cases overwhelming the state’s flood-protection system) and result in more than $300 billion in damage.
The “ARkStorm Scenario,” prepared by the U.S. Geological Survey and released at the ARkStorm Summit in Sacramento on Jan. 13 – 14, combines prehistoric geologic flood history in California with modern flood mapping and climate-change projections to produce a hypothetical, but plausible, scenario aimed at preparing the emergency response community for this type of hazard.
