Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. But it not directly measurable from space, due to the abundance of ozone higher in the atmosphere, which masks the surface. Now, researchers have devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to predict when and where ozone will form.
We need to ensure that our air, water and soil is free of poisons and to do that we need to take pollution control more seriously than we do today. Many industries have found that environmental regulation is compatible with long term production and profits.
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.
