Climate Change Poses Major Risks for Unprepared Cities

A new examination of urban policies has been carried out recently by Patricia Romero Lankao. She is a sociologistspecializing in climate change and urban development. She warns that many of the world’s fast-growing urban areas, especially in developing countries, will likely suffer from the impacts of changing climate. Her work also concludes that most cities are failing to reduce emissions of carbon dioxide and other greenhouse gases. These gases are known to affect the atmosphere. “Climate change is a deeply local issue and poses profound threats to the growing cities of the world.”Says Romero Lankao.“but too few cities are developing effective strategies to protect their residents.”

Cities are major sources of greenhouse gases. And urban populations are likely to be among those most severely affected by future climate change. Lankao’s highlight ways in which city-residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term benefits.

The locations and dense construction patterns of cities often place their populations at greater risk for natural disasters. Potential threats associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat heavily paved cities more than surrounding areas. The impacts of such natural events can be more serious in an urban environment. For example, a prolonged heat wave can increase existing levels of air pollution, causing widespread health problems. Poorer neighborhoods that may lack basic facilities such as drinking water or a dependable network of roads, are especially vulnerable to natural disasters. Many residents in poorer countries live in substandard housing without access to reliable drinking water, roads and basic services.

Local governments, therefore, should take measures to protect their residents. “Unfortunately, they tend to move towards rhetoric rather than meaningful responses,” Romero Lankao writes. “They don’t emphasize mass transit and reduce automobile use. Infact, many local governments are taking a hands-off approach.” Thus, she urges them to change their idle policies and to take strong steps to prevent the harmful effects of climate change on cities.

Free Statins With Fast Could Neutralize Heart Risk

Fast food outlets could provide statin drugs free of charge o that customers can reduce the heart disease dangers of fatty food, researchers at Imperial College London suggest in a new study.

Statins reduce the amount of unhealthy “LDL” cholesterol in the blood. A wealth of trial data has proven them to be highly effective at lowering a person’s heart attack risk.

Ina paper published in the American Journal of Cardiology, Dr Darrel Francis and colleagues calculate that the reduction in heart attack risk offered by a statin is enough to offset the increase in heart attack risk from eating a cheeseburger and drinking a milkshake.

Dr Francis, from the National Heart and Lung Institute at Imperial College London, who is the senior author of the study, said: “Statins don’t cut out all of the unhealthy effects of cheeseburgers and French fries. It’s better to avoid fatty food altogether. But we’ve worked out that in terms of your possibility of having a heart attack, taking a statin can reduce your risk to more or less the same degree as a fast food meal increases it.”

“It’s ironic that people are free totake as many unhealthy condiments in fast food outlets as
