Brumadinho Landslide in Brazil

The Brumadinho landslide occurred on 26 January 2019 in the Brazilian state of Minas Gerais. To date, around 60 bodies have been recovered from the Brumadinho landslide but almost 300 are still missing. Although bodies were recovered it proved very difficult to identify them. The current disaster happened just three years after the collapse of another tailings (waste materials) dam, near the town of Mariana, also in the state of Minas Gerais. It killed 19 people, forced many people to ...

Polar Vortex

Chicago has been affected by temperatures as low as -30°C in January this year. When the wind chill is added to this, it was said to feel like -50°C. The reason behind these unseasonally low temperatures is the polar vortex. The polar vortex refers to upper level winds which normally keep very cold winds in the region around the North Pole. (It is a winter equivalent to the mid-latitude jet stream which sometimes breaks down forming a blocking anticyclone that ...

The New Hong Kong-Zhuhai-Macao Bridge (HKZM)

The new 55-km Hong Kong-Zhuhai-Macao Bridge (HKZM) – the world’s longest sea-bridge, links three main cities in the greater bay Area of China (formerly called the Pearl River Delta). The Bay Area is China’s economic powerhouse, accounting for 14% of China’s GDP in 2017, but only 5% of its population. China’s economy has been slowing down, and there are problems related to inequalities in wealth, an ageing workforce and increasing pollution of air and water. It is hoped that the ...

Burial in China

Around 10 million people die in China each year. Of these about 50% are cremated. The Chinese authorities have looked at ways of reforming burials in China, in order to deal with the lack of space and high prices of burials in certain areas. Each cremation releases around 160 kg of carbon dioxide, so around 800,000 tons of CO2 are released into the atmosphere each year in China, as a result of cremations! As China’s population ages, this amount is likely ...

Peat was cut not only by Bord na Mona, but also by individual ...
