Antartica’s Largest Iceberg Will Soon Be Non-Existent

On its course to the equator, this massive iceberg breaking off of Antartica’s Ross Shelf is nearing destruction.

The iceberg, called B-15, has been drifting away from Antartica for around 20 years, covering more than 6,600 miles. The iceberg has gradually fractured into multiple smaller sections, and the section pictured is called B-15Z.

This map tracks the course of B-15Z over time, and the iceberg is now passing the South Georgian Islands. The iceberg is nearing the equator, and the warmer tropical waters will quickly melt away the gargantuan ice mass,

Chasing Ice

I’ve posted a few things about changing temperatures and human impact consequences, so I wanted to share a documentary that I recently saw called Chasing Ice. This documentary follows environmental photographer James Balog, on his passionate project to give the public visual evidence of global warming. Balog and his team decided to focus on melting glaciers, and the drastic changes that are adding to sea level rise. With the ongoing controversy on the truth of global warming, Balog knew that people needed evidence that they could see with their own eyes. Balog and team of scientists, EIS engineers, and photo assistants, traveled to Greenland, Iceland, and Alaska capturing otherwise never could be seen glacial calving. They set up timer cameras to capture images of glacier melting over a few month period and created a time-lapse video which gave the public a real look into how temperature is effecting these areas. Even though these places seem and are so far away, our daily choices effect them, and in turn will effect us in the future. Be sure to check out the documentary, which can be found on Netflix! Our impact does effect the environment, and now the argument of “not seeing” our effects, can in fact be seen and trust me it will shock you.

Melting Glacier

Sheridan Glacier

This icy glacier, located right outside Cordova, Alaska, is a beautiful spot that has been a popular location to visit while in the area. There are hiking trails, nearby skiing areas, and walkable glacier areas with ice caves. This breathtaking place of nature unfortunately is seeing some changes in size which could be related to shifts in temperature. On http://www.mappler.net/sheridan/ you can see the changes from an aerial view.

As you can see, there are quite noticeable changes between the top photo and the bottom photo. The ice is being separated further and further apart and looks like the result of temperature change.
