The world's megacities that are sinking 10 times faster than water levels are rising

The world's megacities that are sinking 10 times faster than water levels are rising | ApocalypseSurvival | Scoop.it
Scientists have issued a new warning to the world’s coastal megacities that the threat from subsiding land is a more immediate problem than rising sea levels caused by global warming.

 

A new paper from the Deltares Research Institute in the Netherlands published in April identified regions of the globe where the ground level is falling 10 times faster than water levels are rising - with human activity often to blame.

In Jakarta, Indonesia’s largest city, the population has grown from around half a million in the 1930s to just under 10 million today, with heavily populated areas dropping by as much as six and a half feet as groundwater is pumped up from the Earth to drink.

The same practice led to Tokyo’s ground level falling by two meters before new restrictions were introduced, and in Venice, this sort of extraction has only compounded the effects of natural subsidence caused by long-term geological processes.

Inside the Colorado deluge

Inside the Colorado deluge | ApocalypseSurvival | Scoop.it

"Two things that helped make this rainfall historic are breadth and duration. Colorado can get much higher rainfall rates for brief periods and over small areas."

The devastating flooding in Colorado has impacted so many. The rainfall Colorado has experienced makes it the most on record. The massive amounts of flooding and devestation in areas like Boulder are caused by the highly populated valley areas.  

Al Picozzi's curator insight, September 17, 2013 1:13 PM

Almost seems like a perfect storm scenario.  Large amouts of rain over a long perod of time over a large area.  This combined with a late summer/early fall heat wave and tons of moisture in the air, with climate change all contributed to the disater in Colorado.  They also believe the changes made by people to the physical geography over the last hundred years or somade have contributed to teh flooding in the area.  Development can effect the way a place floods.  Where there were once open fields and trees, there are now parking lots and houses which just can't absorb rainfall.  Makes you ask the question, shouldn't there be more study of where we exapnd our cities and what effect this will have in case of a major rainfall, earthquake, blizzard, etc?

Tony Aguilar's curator insight, September 18, 2013 2:27 PM

      What was interesting about this particular deluge was how much rain fell and how it happened in such a short time. Meteroligist high wet density levels of vapor that rose to high altitutdes and was able to condense into water and help in a perfect combination of weather to create a powerfully dangerous flash flood.

    The article recounts a former major colorodo flood that occured in 1978 and had killed over 150 people during a centenial celebration.

   After this occurence warning signs were put up beside the roads to warn travelers of flash flood possiblities and to promote safety. These floods do not happen in Colorado often and are usually a surprise. They do not when the nextmajor flash flood may occur in the boulder region but they know through historical patterns that it will happen again. 

This article stood out to me because I have friends that live in these areas and had to run for safety and move their cars to prevent damage in these same areas. The good thing is that the people that I know from this area are doing ok.

Melting Glaciers Transform Alpine Landscape

Melting Glaciers Transform Alpine Landscape | ApocalypseSurvival | Scoop.it
Climate change is dramatically altering the Swiss Alps, where hundreds of bodies of water are being created by melting glaciers. Though the lakes can attract tourists and even generate electricity, local residents also fear catastrophic tidal waves.

Largest glacier calving ever filmed

"On May 28, 2008, Adam LeWinter and Director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland. The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 3,000 feet, 300-400 feet above water and the rest below water."

The Siberian Times is reporting a record heatwave for towns such as Norilsk that are both North of the Artic Circle and built on permafrost.  While on the global scale the climatic shifts are quite alarming, there are many in Siberia that see global warming as a mixed bag.  In what some would have you believe is an unrelated news item, the North Pole is experiencing the formation of large meltwater ponds

6 Ways Climate Change Will Affect You

6 Ways Climate Change Will Affect You | ApocalypseSurvival | Scoop.it
From the food we eat to the energy, transportation, and water we all need, a warmer world will bring big changes for everyone.

 

B Sinica: This article touches every aspect of geography from culture to climate [considering] how the growing population plays the biggest role in determining the future of life on Earth.  People need to recognize the problems and potential future issues with global warming and the rapidly changing environment.  Though not many issues can be prevented or even solved, the least we can do is try to lessen the severity of devastation and prolong the current conditions as much as possible before the world becomes too extreme to manage.

Brianna Simao's comment, April 30, 2013 7:22 PM
It is kind of a scary thought that global warming could greatly disrupt the way we live. Everyone is affected by it especially businesses like farms. The production of crops declines because of the excessive heat. Changing climate affect the length of each season which hurts the process of growing and harvesting crops. There would also be a change in the production, storage and transportation. It will cost more money to properly manage these businesses. This change will not only affect companies and how we handle our food but also our way of life and health. We would all have to adapt to such drastic changes in the environment which may be a struggle for some. Health wise, if it is too hot and people are not well adapted then it could lead to hospitalization and increased health risks. I don’t think there is much we can do to lessen the severity because it is a natural cycle of earth. I do think we may have sped up the process a little bit, for example car exhaustion and greenhouse gasses. But we are so dependent on such technology we can’t just make it disappear.
Dillon Cartwright's comment, May 3, 2013 1:04 PM
It's crazy that something like a little climate change can change the affect the entire world. Not just in one way either, it affects the world in many ways, like the 6 mentioned above. I don't think people realize the frailty of the environment they live in. Something as small as someones car exhaust becomes kind of a big deal when there are hundreds of millions of cars in the world.
In addition to that, I think it's great that life expectancy has gone up with cures to diseases and advances in modern medicine. It's a good thing that people are living longer lives, but it's a problem when these people aren't environmentally conscious. If there is going to be a consistent increase in population, there should also be an increase in environmental awareness so everyone can work together in slowing down this destructive process.
Victoria McNamara's curator insight, December 12, 2013 10:03 AM

Climate change is going to affect how we live in the future. It will cause lack of food, energy sources, health risks, climate changes, drought etc. It is because of our growing population and the amount of people the world has to take care of for all of us to survive. We are also using too many of its resources too quickly. What could we do now to try to slow down the process of it happening?
