Uncovering Impacts of Gold Mining in Papua New Guinea

From late December 2015 through January, a team of Earth Institute scientists and human rights lawyers from Columbia University worked in the highlands of Papua New Guinea to deliver the results of an independent study of water quality and human rights to the indigenous communities living near an industrial gold mine.

Understanding the Paris Climate Accord and Its Implications

On Saturday, Dec. 12, 2015, 195 countries reached a history-making agreement to reduce their greenhouse gas emissions in order to avert the direst effects of climate change. Here are some of the best and most reliable resources to help you understand the Paris accord and its implications.

From Copenhagen to Paris: Getting Beyond Talk

The climate issue seems to generate a high level of ideologically based politics, emotional rhetoric and political symbolism. It is time to move past symbols to pragmatism and political reality.

The Paris Climate Change Conference – What You Need to Know

The United Nations Climate Change Conference, meeting in Paris from Nov. 30 to Dec. 11, brings together world leaders to craft a new international agreement to keep the average global temperature rise below 2°C by 2100. Here’s what you need to know about it.

The drillers insert the larger diameter 4" PVC pipe into the well.  Handling the 10 meter pipe is challenging.

Last Sample and Home

We finished our work at the river transect. Now we had one more sample to collect. Alamgir had arranged for drillers at this new site, but they were delayed because of a knife fight between two villages over some property.

Hammering the OSL sampler, which is at the end of many auger extension rods.  The sampler fits inside the 3" PVC pipe that had been installed.

OSL Samples at Last

The success of the tube wells for drilling and obtaining samples was a great boon to our field program. We drilled three additional tube wells to complete a five-well transect across the abandoned river valley. When we date the samples, we will find out if the river switched position suddenly, possibly from an earthquake.

Standing ankle deep in mud by the resistivity meter.  The smokestack of the brick factory can be seen in the distance.

Tubewells to the Rescue

The resistivity testing was hampered by bad roads and flooded fields. The augering was proving similarly difficult in the thick muds of the abandoned channel. It was time to change to our alternative plan: drilling with tube wells. That worked better and we had turned a corner.

The large abandoned channel we hoped to work in is completely flooded.

Pani, Pani Everywhere

Heading out to our field area, we discovered that the abandoned river valley we planned to study was completely flooded. There was pani—the Bangla word for water—everywhere.

The Taj Mahal. You can see its enormous size from the line of people waiting to get inside standing on the pedestal. The line completely circled the tomb on this holiday weekend.

Bangladesh and India, Too

Returning to Bangladesh for additional fieldwork, I stopped off in India for several meetings, but we found time for some sightseeing, too. We were able to see the Qutub Minar complex in Delhi as well as the Taj Mahal and Agra Fort in Agra. Plus all the meetings in Delhi, Kolkata and Dhaka were very successful.

What the World Thinks of Climate Change

We all know that climate change can generate great debate in the United States. But what about the rest of the world?
