If U.S. sulfur dioxide emissions are cut to zero by 2100, as some researchers have projected they will be, rainfall over Africa’s Sahel region could increase up to 10 percent from 2000 levels, computer simulations suggest.
Undergraduate sustainability students explored innovative software and 3D printing to create a set of possible solutions to help Singapore cope with a big problem: haze and air pollution drifting over the city state from burning forests in neighboring Indonesia.
Undergraduates from Columbia and Barnard will be able to serve as research assistants on research projects related to sustainable development and the environment with distinguished faculty and researchers at the cutting edge of this burgeoning field.
In fall 2015, smoke from agricultural fires in Indonesia blanketed much of equatorial Asia. Schools and businesses closed, planes were grounded and tens of thousands of people sought treatment for respiratory illnesses. In a new study, researchers estimate that the smoke caused upward of 100,000 deaths across Indonesia, Malaysia, and Singapore.
By the Numbers: Air Quality and Pollution in New York City
New York City is known for many things, but having clean air isn’t one of them. Explore some of the issues and challenges the Big Apple faces in clearing NYC’s air through interactive maps and data.
The investment in environmental clean-up often stimulates other upgrades that enable businesses to more effectively compete in a global economy. Moreover, a clean environment reduces illness and that reduces the need for expensive health care.
The problem of air pollution in China continues to reach new heights. To combat the problem in any real way stringent regulation is needed. A new paper from Columbia University’s Earth Institute finds that this can be done without hurting job creation.
Air pollution, both outdoors and indoors, causes millions of premature deaths each year. The deaths are mainly caused by the inhalation of particulate matter, especially black carbon. But black carbon not only has impacts on human health, it also affects visibility, harms ecosystems, reduces agricultural productivity and exacerbates global warming.
Looking at regional differences in PM2.5 concentrations gives us a sense of the changing face of air quality throughout the world.
