Has Beijing found a solution to smog?


Daan Roosegaarde, a Dutch artist and innovator, has invented a giant seven-metre-tall (23 feet) air purifier that is set to be tested this coming September in the city with 21 million residents.

The colossal device, named Smog Free Tower, is the largest air purifier in the world, claims Studio Roosegaarde. 

It can collect pollutants, process them and then condenses it into cubes measuring around four centimetres (1.6 inches).

The tower, standing about two stories tall, can clean 30,000 cubic metres (1,060,000 square feet) of fine smog per hour and uses no more electricity than a water boiler.

He teamed up with experts and designers from his studios to make the machine over a period of two years.

Everything is possible except and effort to reduce the CO2 emissions


Concentration of CO2 in atmosphere hits new high



Petteri Taalas, secretary-General of the World Metheorological Organization, an institute depending of the UN has said that levels of CO2 in the atmosphere have surged past an important threshold and may not dip below it for ”many generations”.659


The 400 parts per million benchmark was broken globally for the first time in recorded history in 2015.

But according to the World Meteorological Organisation (WMO), 2016 will likely be the first full year to exceed the markcarbon-dioxide


Prior to 1800 atmospheric levels were around 280ppm, according to the US National Oceanic And Atmospheric Administration (Noaa).

The WMO says that the rise through the 400ppm barrier has persisted and it’s likely that 2016 will be the first full year when the measurements show CO2 above that benchmark, and ”hence for many generations”.
