Olympic Park, Sochi

Here’s a “before-and-after” view of the Olympic Park showing some of the transformation that has occurred in the vicinity of Sochi to accommodate the ongoing Winter Olympics:

Timelapse: Three Decades of Powder River Basin Coal Mining

Earlier this year Google launched the Timelapse project,  a global interactive map that uses three decades of Landsat imagery to show how our world is changing. One stunning example of human impact on the planet is the rapid buildout of Powder River Basin coal mines in the Thunder Basin National Grassland.

In addition to domestic power production, coal exports are an increasingly controversial issue as demand in Asia increases. Exporting coal means even more mining here at home, long coal trains transporting it to ports through busy cities, increased train derailments, and more dirty coal terminals that spill and flood

If you can’t see the embedded map above, please check it out on our website: http://skytruth.org/issues/mining/energy/

Be sure to check out past posts on this issue to see mines like this one compared with more familiar features like San Francisco, and get an idea how big the trains are that carry all this coal to foreign markets. And do some skytruthing of your own at: 

Panama Canal Getting Bigger. Much Bigger.

A man, a plan, a canal. Panama!

It’s not just a quaint anagram. In this age of relentlessly expanding global commerce, Panama has been planning ahead, and is investing billions of dollars in supersizing the canal (photo gallery here) to allow the passage of the new breed of supersized cargo ships.  Even more coal mined from Appalachian mountains and Montana/Wyoming prairies — and possibly natural gas extracted from shale by hydraulic fracturing — will likely be shipped to Asia and other markets once this expansion work is completed.

The global warming-driven decline in Arctic sea ice might divert some of the cargo traffic Panama is counting on to pay for this expansion, if the Northwest Passage becomes a viable trade route. So in a bit of irony, by feeding the world’s addiction to fossil fuels, Panama may be undercutting its business plan.  Just sayin.

Here are a couple of images from Google Earth showing the area around the Caribbean end of the Panama Canal near the Gatun Locks, as it appeared in 2005 and with the expansion project well underway in 2012.

More post-Sandy NOAA Aerial Photography Available

NOAA has posted a new set of post-Hurricane Sandy aerial photography covering much of the New Jersey shoreline and parts of the New York City metro area.  The images were shot yesterday, November 1.

It’s remarkable how much beach erosion is evident from these photos.  It’s possible the “before” images were taken during low tide, but breaking waves are apparent much closer to roadways and homes along the shore than on the pre-Sandy photos.

Here are a few examples to follow up the ones we posted yesterday.  You can view all the photos from October 31 and November 1 on NOAA’s handy interactive website. NOAA has also created a small gallery of before/after image pairs using a neat slider tool for easy comparison. [Another, bigger gallery is here.]


BEFORE: Lake Como, NJ.


AFTER: Flooded neighborhoods surrounding Lake Como, NJ. November 1, 2012.

BEFORE: Beach near Monmouth, NJ.

Before-After Aerial Photography Shows Damage, Shoreline Changes from Hurricane Sandy

NOAA has published their first round of post-Hurricane Sandy aerial survey photography, covering the Atlantic coastlines of parts of Maryland, Delaware and New Jersey.  You can view this detailed, high-resolution color imagery in a convenient, easy to use map viewer.  You can choose a street map or recent Google imagery for a backdrop; and you can flicker between that backdrop and the new aerial imagery by toggling the check boxes next to the aerial imagery layers shown along the left side of the map, to get a direct “before and after” comparison.

In many places, the damage is quite stark.  Homes and businesses have vanished.  The shoreline has changed dramatically, and new inlets have opened up.  Here are a few examples that we found after just a few minutes of review.  The post-Sandy images in these examples were shot yesterday (October 31):

BEFORE: Bridge south of Point Pleasant, NJ.
AFTER: New inlet; damaged/destroyed houses; flooding. October 31, 2012.
BEFORE:  Amusement park, Seaside Heights, NJ.
AFTER:  Partial collapse of amusement park pier; wreckage of roller coaster lying in surf (see photo below); mounds of debris piled up on beach. October 31, 2012.

AFTER: Severe erosion, dune washover, shoreline change. October 31, 2012.

We’ll be looking for more NOAA aerial survey photography in coming days, covering additional parts of the affected coastline.  Let us know if you see anything you find particularly interesting.
