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.

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”.

How Can We Make People Care About Climate Change?

http://e360.yale.edu/feature/how_can_we_make_people_care_about_climate_change/2892/Norwegian psychologist Per Espen Stoknes has studied why so many people have remained unconcerned about climate change. In a Yale Environment 360 interview, he talks about the psychological barriers to public action on climate and how to overcome them. Read the article by Richard Schiffman i Environment 360.

 

Cranes flying between Extremadura and Southern Sweden

 

Sunset at HornborgasjönCranes that breed in southern Sweden overwinter usually in Extremadura, in southwestern Spain. The cranes fly every year from Spain to Sweden in March. After a cold autumn night, maybe in the beginning of October, the cranes leave Hornborgasjön. Breakup is magnificent. Groups of birds takes height and head south, to a pleasant winter in Spain.
Hornborgasjön is one of the 51 wetlands in Sweden we have particular responsibility under the Wetlands Convention. The lake is just over 10 kilometers long and two to three kilometers wide. The area is about 35 square kilometers. Maximum water depth is 1.5 meters (at mean water level). Water level can, in extreme cases, vary by almost two meters during the year. The lake harbors some 50 breeding wetland dependent species. A total of 290 species have been seen in the area.

Economic Growth and Sustainable Development

2015 marked the target date for the achievement of the Millennium Development Goals and the start of the post-2015 development and climate processes, which ultimately aim to eradicate poverty, improve people’s lives, and rapidly transition to a low-carbon, climate-resilient economy, are mutually reinforcing: when acted on together, they can provide prosperity and security for present and future generations.

Sustainable development, which balances current needs with the needs of future generations, is at the core of the UN’s development agenda.

The UN has shifted to the idea of sustainable development in part because of climate change.  According to the Intergovernmental Panel on Climate Change, if climate change is left unchecked, it will increase the likelihood of severe, irreversible changes to our ecosystems. Sustainable development, because it is less harmful to our ecosystems, can help in the fight against climate change.  Sustainable development will also help the development needs of the poor and most vulnerable, who have contributed the least to the climate change problem.miljogruppenUN
