International travelers experience adverse cardiopulmonary health effects even after short stay in polluted cities

Green Car Congress

For travelers who visit cities with high levels of air pollution, even a short stay leads to breathing problems that can take at least a week from which to recove, a new study led by researchers at NYU School of Medicine finds. The study is the first of its kind, say the authors, to analyze pollution-related coughing and breathing difficulties and recovery times upon returning home, in healthy, young adults who’ve travelled internationally.

Study links air pollution and cyclone intensity in Arabian Sea; suggested solutions include diesel filters and two-stroke engines running on LPG fuel

Green Car Congress

Pollution is making Arabian Sea cyclones more intense, according to a study in the journal Nature. We’re showing that pollution from human activities as simple as burning wood or driving a vehicle with a diesel engine can change these massive atmospheric phenomena in a significant way. Cyclone Phet in 2010 struck the coastlines of Pakistan and Oman and caused nearly $2 billion in damage. Scientists are working to better understand atmospheric brown clouds and their effects.

Air pollution is the leading environmental cause of death worldwide according to the State of Global Air 2018 , the annual report and interactive website published by the Health Effects Institute (HEI). Ozone, another important component of outdoor air pollution, whose levels are on the rise around the world, contributed to 234,000 deaths from chronic lung disease. All told, long-term exposure to outdoor and indoor air pollution contributed to 6.1

Global CO2 emissions stalled for the third year in a row

Green Car Congress

Emissions are increasing in other developing countries: 6% for Indonesia and Malaysia; 9% for Pakistan and 12% for the Philippines. Information on the other two greenhouse gases, methane (CH 4 ) and nitrous oxide (N 2 O), is only available until 2012, as international statistics on agricultural activities—the main source of these emissions—are not updated as frequently as on energy and industry-related activities.

2018 Environmental Performance Index: Air quality top public health threat

Green Car Congress

Recent research cited by the EPI suggests that around five million people die prematurely every year due to air pollution, accounting for approximately one in every ten deaths annually. Substantial populations still suffer from poor air quality, most notably in India, China, and Pakistan. The 2018 Environmental Performance Index (EPI) finds that air quality is the leading environmental threat to public health.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

While carbon dioxide is the primary driver of global warming over the long term, limiting black carbon and methane are complementary actions that would have a more immediate impact because these two pollutants circulate out of the atmosphere more quickly. The team considered about 400 emission control measures to reduce these pollutants by using current technology and experience. Iran, Pakistan and Jordan would experience the most improvement in agricultural production.
