What the Earth would look like if all the ice melted

We learned last year that many of the effects of climate change are irreversible. Sea levels have been rising at a greater rate year after year, and the Intergovernmental Panel on Climate Change estimates they could rise by another meter or more by the end of this century.

Changes on the Cape Cod Coastline

Changes on the Cape Cod Coastline | STEM Connections | Scoop.it
Beaches are dynamic, living landscapes. The coast off of Chatham, Massachusetts, provides a prime example of beach evolution.

To quote coastal geologist Robert Oldale, "Many people view coastal erosion as a problem that needs to be addressed and, if possible, prevented.  However, storm and wave erosion along the shore of Cape Cod has been going on for thousands of years and will likely continue for thousands of years more. It is a natural process that allows the Cape to adjust to rising sea level. Erosion is only a peril to property. If we build on the shore, we must accept the fact that sooner or later coastal erosion will take the property away.”

The NASA Earth Observatory is a teaching tool used to assist educators in teaching students about the environmental, including natural hazards with visualizations depicting the date and time these vast changes in the climate occurs. There are multiple global maps which  depict data over a period of time which can be used as a tool to see the effects of global warming it’s the implications on the environment on a global scale. Animations, videos and side by side images are also available to teachers to show how sustainable choices or designs can influence our environment. I really enjoyed looking at all of the real-world images on this site and it opened my eyes to how creating a more sustainable environment could influence our world on a global scale.

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 | STEM Connections | 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.
