Researchers at the Stockholm Environment Institute (SEI) at the University of York have played a key role in a new study that shows that implementing 14 key air pollution control measures could slow the pace of global warming, save millions of lives and boost agricultural production.

Elizabeth Demaray, an associate professor of fine arts, is cultivating lichen on the sides of New York City skyscrapers to counteract the lack of native vegetation found in the city. Her "Lichen for Skyscrapers Project" was featured as part of New York's Art in Odd Places Festival from Oct. 1-10 and is currently on view as a site-specific installation on 14th Street between Union Square Park and the Hudson River. "Metropolitan centers figure into local temperatures in an interesting way," Demaray says. "They are sometimes referred to as 'urban heat islands' because they create heat and they trap heat. A large part of this process is due to the materials that we build with and the actual architecture of the buildings that we create." Demaray says one of the ways to reduce heat in these cities is to cultivate lichen, which forms a protective barrier, insulating its supporting building from harmful elements. It can lower cumulative temperatures by absorbing sunlight and reflecting heat due to its light color palate while making oxygen and creating green space on the sides of buildings.

More than half the world's population live in cities, many of which are increasingly vulnerable to the impacts of climate change. But cities are also emerging as the innovative "first responders" in dealing with climate change, says a major new report led by researchers at Columbia University and the City University of New York (CUNY) and published by Cambridge University Press.

A team of scientists in the United Kingdom and the United States has warned that the native fauna and unique ecology of the Southern Ocean, the vast body of water that surrounds the Antarctic continent, is under threat from human activity. Their study is published this week in the peer-reviewed journal Annals of the New York Academy of Sciences.

There are few things journalists like to discuss more than, well, themselves and the long-term prospects for their industry. How long will print newspapers survive? Are news aggregation sites the future? Or are online paywalls - such as the one the New York Times just launched - the way to go? As media organizations plot their future, it's worth discarding some misconceptions about what it will take to keep the press from becoming yesterday's news.

A new analysis, published this week and conducted by a team of scientists led by Drew Shindell of NASA's Goddard Institute for Space Studies (GISS) in New York City, shows stricter vehicle emission standards would yield major health, agricultural, and climate benefits.

Bloomberg's office says the new initiatives include plans to build solar power plants on capped landfills and launch a loan program to help property owners pay for green energy efficiency upgrades.
