The presence or scarcity of vegetation is an essential factor in determining how much urban areas heat up, according to a NASA study. Using data from multiple satellites, the researchers found that areas covered in part by impervious surfaces such as asphalt, concrete, and steel had an average summer temperature 3.4 degrees F higher than nearby rural areas. The highest U.S. urban temperatures compared to surrounding areas were along the Interstate-95 corridor from Boston to Washington and around Atlanta and the I-85 corridor in the Southeast. In desert cities such as Phoenix, the urban area was actually cooler because irrigated lawns and trees provide cooling that dry, rocky areas do not, the researchers explain. The urban heat island effect, as the phenomenon is known, occurs primarily during the day, when impervious surfaces in cities absorb more sunlight than surrounding vegetated areas. Plants naturally lower surrounding surface temperatures by releasing water back into the atmosphere during photosynthesis. An increase of just 1.8 degrees F can raise energy demands for air conditioning from 5 to 20 percent in the United States, according the Environmental Protection Agency.
This week, Mayor Miguel Angel Mancera celebrated the Day of the Pedestrian by announcing strong new policies to reduce speed limits and to increase penalties for dangerous driving. In doing so, he ushered in a new era of traffic safety in Mexico City.
Mayor Mancera’s actions reflect a growing global recognition of road safety as global health crisis. Around the world, 1.24 million people die in car crashes annually, including 1,100 in Mexico City in 2012—an average of three people killed every day. According to the World Health Organization, road traffic injuries are expected to become the seventh leading cause of death globally by 2030. The tragedy is that each traffic death is preventable. As we saw in New York City over the last decade and in our ongoing work with cities around the world, lives can be saved through strong road safety laws and increased enforcement. Yet nearly 85 percent of nations globally don’t have adequate traffic laws to help counter traffic deaths and injuries.
Mexico City joins world class cities like New York and London in addressing the number-one killer on its streets: speeding. It may seem strange to limit speeding on roads that are frequently clogged with traffic, but statistics show that large streets account for more than 50 percent of the pedestrian fatalities in Mexico City. The difference in 20 km/h in speed can be the difference between life and death, which is why lowering speed limits on primary roads from 70 to 50 km/h will save lives. And even a moment of distraction can take a life, which is why texting or making calls while driving must be treated as a serious threat to the safety of everybody on the street.

Given all the urban parks, hedge mazes, and scientifically accurate themed gardens of the world—two of my favorites being the exquisite Silver Garden at Longwood Gardens and the scifi otherworldliness of the Desert Garden at the Huntington—surely there is room for a kind of translation landscape?
The Texas A&M Transportation Institute recently unveiled their semi-regular report on urban traffic congestion. Chances are you read about it in your local news outlet. While the focus and themes of the report are largely the same as previous years, big changes are underway in how we study, think about, and address metropolitan traffic congestion. This new, modern approach calls into question whether the endless pursuit of congestion relief makes sense anymore as a practical policy goal.
Honeybees play a crucial role in pollinating crops. The BEEcosystem observation hive has been designed to help combat falling bee numbers by encouraging people to take up beekeeping and get educated about bees.
