For about 10 years, environmental law professor Karl Coplan has been trying to winnow down his direct footprint of CO2 emissions. He has been successful, and has just published a book chronicling his efforts.

My last days in the field brought us to monuments in a makeshift home near the ocean, a flooded field next to a school, and adjacent to a jute mill. Most of us now head back to Dhaka, the capital. Céline will stay on a few more days, then Hasnat with Saif and Nahin will continue until all the monuments are resurveyed.

We continued our GPS surveys of monuments to measure land subsidence. While the work general went very well, we faced challenges from obscured or tilted monuments. We also struggled with large traffic delays, particularly at unpredictable ferry crossings.

Getting to remote sites started to prove challenging, and involved many forms of transportation by land and water.

I am back in Bangladesh once more to investigate the balance between sea level rise, the sinking of the land, and the filling of the space with sediments.

New study challenges many climate scientists’ expectations that plants will make much of the world wetter in the future.

Artificial and modified organisms could become essential tools to fight climate change, clean up pollution, protect biodiversity, and more.

Lower air pollution levels saved an estimated 5,660 lives in New York State in 2012, compared to 2002 levels, according to a new study.

We added a campaign monument to the tide gauge at Khepupara on the way to our last GPS and SET installation site at Patuakhali. We faced challenges such as bad roads and broken bridges, and leeches, but got the work done. The field work was now coming to a close.

We replaced the GPS at Khulna University, then met some colleagues in Barisal. We continued to Khepupara and the beach at Kuakata for more installations. The beach on the Bay of Bengal is fresh water in the summer due to the enormous water discharge at the Ganges-Brahmaputra Delta.
