Jacob Crowell's curator insight, October 14, 2014 3:25 PM

This is an interesting way to graph out the urban footprints of various cities from around the world. This also shows how the United States has a number of the largest urban centers in the world. Along the top, New York, Chicago, LA, and Miami are massive compared to cities like Hong Kong. This shows how in the United States there are massive amounts of urban growth. Even in China where their population is one of the worlds biggest, Hong Kong a major city only has 7.1 million. In the United States, for the past century cities have been growing and this graph shows that.

Samuel D'Amore's curator insight, December 14, 2014 6:40 PM

These visuals really help to show that the size of a city doesn't necessarily correspond with it's population. Many years ago the trend was the larger the city in turn it would posses a larger population than a physically smaller city. Today this no longer holds true, in fact many smaller cities vastly out populate large sprawling cities. Most of these mega-cities in Asia and Latin America are incredibly over build and densely packed surrounded by miles of slums. 

Edgar Manasseh Jr.'s curator insight, January 22, 2015 7:16 PM

Pretty cool.

Coastal Risk Australia

Coastal Risk Australia | Lorraine's Environmental Change &  Management | Scoop.it
The Coastal Risk Australia website has been developed to help communicate the risks of coastal flooding associated with sea level rise and storm surge. There is robust evidence that sea levels have risen as a result of climate change based on observations from tide gauges, paleo indicators and satellite measurements. The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report found that over the last century global average sea level rose by 1.7 [1.5 to 1.9] mm per year. In recent years (between 1993 and 2010) this rate has increased to 3.2 [2.8 to 3.6] mm per year. The IPCC report finds that the rate of sea level rise over the last century is unusually high in the context of the last 2,000 years.
Australia is a coastal society, 85 per cent of the population lives in the coastal region and it is of high economic, social and environmental value to the nation. Nearly 39,000 residential properties are located within 110 metres of soft, erodible shorelines. Exposure will increase as Australia's population grows.
The impacts of sea level rise will be experienced mainly through its effect on extreme sea level events such as high tides and storm surges. Rising sea levels will increase the frequency or likelihood of extreme sea level events and resultant flooding.

Ghazlan Mandukai, 52, left, looks out over the vast, toxic tailings lake beyond the industrial city of Baotou, Inner Mongolia. He farmed in this area for 40 years until the influx of steel and rare earth metal factories rendered local lands infertile. Poisonous waste that results from refining rare earths is continually dumped into the Weikuang Dam, as seen here.
