World's Biggest NO2 Emissions Hotspots Revealed
Greenpeace has revealed the world's largest nitrogen dioxide (NO2) air pollution hotspots across six continents, and identified Mpumalanga, South Africa as the biggest NO2 hotspot, even outranking areas in China, India and the U.S.
The lush, green province is home to the southern half of Kruger National Park and the iconic Blyde River Canyon. At the same time, it's home to a dozen coal fired power plants owned and operated by the power utility Eskom.
NO2 is a dangerous pollutant that's emitted when fossil fuels such as coal, oil, gas or diesel are burned at high temperatures, and also comes from transportation, forest fires and crop burning. The gas can react to create smog, acid rain and is central to the formation of fine particles and ground ozone, which are both linked to adverse health effects.
"The health toll from these emissions shows the need for an energy revolution that eliminates our reliance on fossil fuels: renewable power generation, energy efficiency, transport and mobility systems that rely less on private cars, as well as electric vehicles," Greenpeace explained in a report.

Greenpeace's new analysis is based on data produced by the European Space Agency's Sentinel 5P satellite, which measures air pollution in the atmosphere, between June to August 2018.
Besides Mpumalanga being the biggest NO2 hotspot, the findings show that China has the world's highest number of individual hotspots, followed by the Middle East, the European Union, India, the U.S. and the Democratic Republic of Congo, Quartz Africa noted from the study.

"The map also points to the impact of emissions regulations in some places. While there are plenty of coal plants in the U.S., NO2 concentrations near plants in India, South Africa, Australia and Indonesia stand out much more. In these countries, there has been a failure to enforce meaningful pollution standards, or to implement them," Greenpeace's journalism unit, Unearthed, pointed out.

Greenpeace researchers noted that the extreme NO2 pollution levels emanating from Mpumalanga blow into the nearby cities of Johannesburg and Pretoria.
"Because South Africa's coal-belts are hidden from view for the majority of South Africans, it can be easy to pretend that they don't actually exist. The reality is that coal extraction and burning has devastating impacts on the people living in the area," Melita Steele, the senior climate and energy campaign manager of Greenpeace Africa, said in a press release. "This satellite data now confirms that there is nowhere to hide: Eskom's coal addiction in Mpumalanga means that millions of people living in Johannesburg and Pretoria are also impacted by the pollution from coal."

Cities such as Santiago de Chile, London, Paris, Dubai and Tehran were also singled out by the analysis due to transport-related emissions.
"Air pollution is a global health crisis, with up to 95 percent of the world's population breathing unsafe air," Steele continued in the press release. "South Africa is a significant global hotspot with its high concentration of coal power stations and its weak air pollution standards. Our Government urgently needs to come up with an action plan that protects millions of people, instead of dirty coal power stations."

One hundred seconds to midnight. That's how close humanity is to the apocalypse, and it's as close as the world has ever been, according to Wednesday's annual announcement from the Bulletin of the Atomic Scientists, a group that has been running its "Doomsday Clock" since the early years of the nuclear age in 1947.

The majority of Americans are stressed, sleep-deprived and overweight and suffer from largely preventable lifestyle diseases such as heart disease, cancer, stroke and diabetes. Being overweight or obese contributes to the 50% of adults who suffer high blood pressure, 10% with diabetes and additional 35% with pre-diabetes. And the costs are unaffordable and growing. About 90% of the nearly $4 trillion Americans spend annually for health care in the U.S. is for chronic diseases and mental health conditions. But there are new lifestyle "medicines" that are free that doctors could be prescribing for all their patients.
Taking an unconventional approach to conduct the largest-ever poll on climate change, the United Nations' Development Program and the University of Oxford surveyed 1.2 million people across 50 countries from October to December of 2020 through ads distributed in mobile gaming apps.
