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

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.
Silting rivers and bad roads made it difficult to find a last site. After a successful installation and an upgrade to an existing GPS site, we left the boat for land. We then discovered the local river had washed away some of our equipment.
We sailed to Hiron Point in the Sundarban Mangrove Forest to upgrade old and install new equipment. I have been to this beautiful remote site several times before. After competing the work, we sailed for over a day to reach our next site on a primary school roof.
By working a 16-hour day, we managed to get both GPS and SETs completed at our first field site. We then sailed into the Sundarban Mangrove Forest, the world’s largest, to visit an existing site and make measurements.
I am back in Bangladesh for a new project examining the balance between sea level rise, land subsidence and sedimentation. We will be installing, repairing or upgrading equipment to measure changes to the landscape.
Warming temperatures, rising seas, and more extreme weather are going to cost us. But they’ll create new business opportunities, too.
In an unusual new study, scientists say they have detected a growing fingerprint of human-driven global warming on global drought conditions starting as far back as 1900.
A new book, the second in a series of primers with the Earth Institute imprint, provides an interdisciplinary overview drought, bringing together many fields including climate science, hydrology and ecology.
Upmanu Lall is director of the Columbia Water Center, and the lead author of the new U.S. National Climate Assessment’s chapter on water resources. The report paints a dire picture of the nation’s climate future. We spoke with Lall about the outlook for water supplies, quality and infrastructure.
