Tree Sitters Block Bayou Bridge Pipeline Construction in Atchafalaya Basin

Tree Sitters Block Bayou Bridge Pipeline Construction in Atchafalaya Basin
ATCHAFALAYA NATIONAL HERITAGE AREA, LA: Water protectors living high in the canopy of old growth cypress trees brought construction on the Bayou Bridge pipeline to a halt earlier today in the Atchafalaya Basin, the largest swamp in North America.

The action – known as a tree sit– was initiated to amplify pleas from Louisiana residents who have begged their local elected officials to protect these ancient trees from destruction by the pipeline company and to provide an evacuation route for the predominantly African American St. James community, which sits at the tail end of the 163-mile Energy Transfer Partners project.

The Bayou Bridge Pipeline

The Bayou Bridge Pipeline (BBP) would impact numerous communities across Southern Louisiana. The pipeline would lead to more fracking for oil in the shale fields of North Dakota and further the global dependence on climate change-causing fossil fuels.

"The High Plains Aquifer, also known as the Ogallala Aquifer, is under stress. Farmers today have to drill ever deeper wells in order to pump water for irrigation, and one recent study found the aquifer to be under more strain than any other in the United States."


Facts about the depletion of the Ogallala Aquifer:

The industrial-level pumping of water from the aquifer began after World War II.

By 1980, the aquifer's water levels had dropped by at least ten feet in most of the regions that took advantage of it.

Some regions of the High Plains, at that same time, had seen a 100-foot drop in their water level.

These days, the water being pulled out of the aquifer annually is equal to eighteen Colorado Rivers.

The northern end of the Ogallala Aquifer is less affected by the overuse. The southern end is the part of the aquifer that is less likely to recover, as it doesn't receive as much precipitation annually.

Shown below is a map of the Ogallala Aquifer, how long it has been irrigated in different regions, and a link to the full article.

Using Landsat to track patterns in irrigation may help water managers sketch out a more sustainable future for the Ogallala Aquifer in the central United States.

NASA’s Parker Solar Probe is aiming for the sun | Science News
"NASA’s Parker Solar Probe is about to embark on one daredevil stunt of a space mission.
Slated to launch August 4, the probe will be the first spacecraft to swoop through the sun’s outer atmosphere, or corona, a roiling inferno of plasma heated to several million degrees Celsius.

The solar probe, if all goes well, is set to circle the sun two dozen times during its seven-year mission. It will be orbiting the sun from approximately six million kilometers away and at a speed of around 700,000 kilometers per hour. The Parker Solar Probe will observe the corona and the solar wind created by the sun. Both of which will likely help in learning more about the sun and its atmosphere. The information gathered from this mission will help future space travel.

Along with the probe will be the names of those who filled out a "Send Your Name To The Sun" submission at http://parkersolarprobe.jhuapl.edu/The-Mission/Name-to-Sun/ before the deadline back in April.
