With longer and hotter heat waves in the offing, a Harvard professor has put the urban “heat island” under the microscope, finding smaller heat islands — mainly occupied by the poor — within city limits, and identifying features that could counter their effects.Hurricane Sandy’s toll on New York and New Jersey brought into stark relief the threat that rising sea levels pose to urban areas, sending officials around the world scrambling to begin efforts to mitigate climate change. But Joyce Klein Rosenthal, an assistant professor of urban design, said it would be a mistake if those plans focused on coastal storms and sea level rise to the exclusion of heat waves.The deadly potential of heat waves has become clearer in recent years, most strikingly through an August 2003 heat wave in France that caused an estimated 14,800 excess deaths. Further, climate modelers believe that by 2050, heat-related deaths may be up 70 percent in the New York City region alone.What that means, Rosenthal said, is that it’s important to think about ways to cool the city’s hot spots, as well as protect its coastal communities and move utility connections out of the basement.“Everyone in the design community was galvanized by Sandy and we absolutely need to work on coastal solutions, but we also have to be mindful that sea level isn’t the only threat,” Rosenthal said.The new study is one of the few to examine the effects of extreme heat within New York. Published in the journal Health and Place, it was conducted by Rosenthal, Patrick Kinney from Columbia University, and Kristina Metzger, formerly of the New York City Department of Health and Mental Hygiene.The report analyzed heat-related mortality rates in residents over 65 among 59 New York community districts and 42 United Hospital Fund neighborhoods between 1997 and 2006. Citywide, it found a 4 percent increase in deaths on the hottest days, those with a heat index of 100 or greater. The deaths were unevenly distributed, however, with higher rates in neighborhoods in the southern and western Bronx, central Brooklyn, northern Manhattan, and the eastern side of midtown.In examining neighborhood effects, the study showed a strong correlation between excess deaths and poverty, poor housing quality, hypertension, and impervious land cover.“It is known that there is an unequal distribution of risk from climate change around the world,” Rosenthal said. “What’s less known is that there is a significant variability of risks from climate change and extreme events within American cities, related to poverty and conditions in the built environment.“It’s very important to recognize that designers, architects, and urban planners have the capacity and agency to improve urban conditions. What’s exciting to me is that, through intra-urban analysis of the effects of place on health, we can focus on modifiable exposures. If we understand the finer-scale spatial and social patterns of vulnerability within cities, we have a better chance at implementing more effective adaptive strategies with communities.”To be sure, Rosenthal said, several cities — New York among them — have taken steps to ease the heat for vulnerable residents, with longstanding programs to distribute fans and air-conditioners and open cooling centers on the hottest days. Some cities have developed “cool roofs” projects and building code requirements that encourage re-covering acres of black tar roofs with light-colored materials that mitigate rather than intensify the heat.The study provides data to support such efforts, and to add trees and parks to the built environment, Rosenthal said. Some interventions can be as simple as putting bars on windows, so that elderly residents feel secure enough to open them. Other programs that give residents a break on electric bills can encourage the use of air conditioners.“Studies like this provide health outcome-related evidence supporting adaptive interventions,” Rosenthal said. “We have health disparities in the spatial distribution of excess mortality of seniors during heat events. The types of characteristics we found to be associated [with that mortality] are within the collective ability of municipalities to intervene.”Rosenthal framed heat as another environmental pollutant, disproportionately affecting the poor and communities of color.“Heat, like ground-level ozone, is an environmental stressor, unevenly distributed in places where there are less trees, less green space, and associated with poorer housing quality,” Rosenthal said. “At every scale [examined], income levels are associated with surface temperatures. Poorer neighborhoods are hotter; wealthier neighborhoods are cooler. Urban design strategies can make a difference in reducing urban micro-heat islands.”Rosenthal said an aging population, a hotter climate, and a lack of affordable housing, if not addressed, may constitute a “perfect storm” for future heat wave deaths.“It’s really a great concern, and one that needs to be taken seriously. This study adds evidence: Does greening a neighborhood make a difference? Can efforts to improve livability of a neighborhood make a difference? The answer is yes. The disciplines of the built environment — urban planning, architecture, landscape architecture, and urban design — have the knowledge and responsibility to make a difference.”
Belgian tanker shipping company Euronav Tankers NV has acquired the ultra large crude carrier (ULCC) Seaways Laura Lynn from Oceania Tanker Corporation, a subsidiary of International Seaways.The ship is the second of the two ULCCs that exist in the global fleet and has been renamed Oceania and registered under the Belgian flag.The 2003-built Seaways Laura Lynn, which features a massive 441,561 dwt capacity, cost Euronav USD 32.5 million.The company already owns the other ULCC, the 442,470 dwt TI Europe, built in 2002.“Bringing the only other ULCC in the world fleet under our control will provide us with a significant strategic opportunity,” Paddy Rodgers, CEO of Euronav, said.The company has just completed the merger with US-based crude oil shipping company Gener8 Maritime, as disclosed at the beginning of this month.The merger creates a crude tanker operator giant with 76 operating crude tankers, consisting of 43 VLCCs, 27 Suezmaxes, 2 ULCCs, two Panamax tankers and two FSOs under joint venture.
Mathieu Flamini believes Chelsea boss Jose Mourinho has done Arsenal a “good favour” in selling Petr Cech to the Gunners. Press Association He is now likely to start at Wembley on Sunday when his new club Arsenal meet Mourinho’s Premier League champions in the Community Shield. The traditional curtain-raiser will give Arsene Wenger a chance to measure his current Arsenal side against the league’s yard-stick and Flamini feels the acquisition of Cech is something the club must make use of. “I was surprised by Mourinho because he really doesn’t do that,” Flamini was quoted as saying in several national newspapers. “He (Mourinho) is a competitor and usually doesn’t like to sell any players to his rivals, but it’s a good favour for us and now we have to take advantage. “It’s a top signing. That’s why we have been lucky on this one.” Having added the attacking talents of Mesut Ozil, Alexis Sanchez and Danny Welbeck in recent summers, Wenger has now strengthened at the other end of the pitch – and France international Flamini reckons the advantages of having Cech on board stretch beyond his goalkeeping abilities. “It’s very important. Not only for his quality but also for his character,” added Flamini. “When you play at the top level, the leaders on the pitch make the difference. “Not only when things go well but especially when things go bad. So, for us, Petr Cech is a top signing. “He is someone with character, someone with a winning mentality.” The 33-year-old goalkeeper ended a long association with Chelsea to move across London to the Emirates Stadium earlier in the summer. Having lost his position as first-choice stopper to Thibaut Courtois, Cech was allowed to leave Stamford Bridge even though Mourinho was keen to keep hold of the Czech Republic international.
