Gizmodo on populations

Daniel Kolitz, a writer for Gizmodo, a science and technology website with many readers, runs a weekly feature called Giz Asks, in which he poses a simple question to a handful of relevant experts.  This week’s question is: Is the world overpopulated?

Jesse Ausubel draws on our carrying capacity work to offer an answer:  https://earther.gizmodo.com/is-the-world-really-overpopulated-1834854464

Ocean Policy session on Capitol Hill

13 March 2019 the Consortium for Ocean Leadership (COL) held its annual Public Policy Forum. The topic was U.S. Ocean Policy: Past, Present, and Future, and used as a point of departure  the 2004  U.S. Commission on Ocean Policy report An Ocean Blueprint for the 21st Century.  Jesse Ausubel led off and moderated the final hour-long session on future ocean policy, videotaped here.

The Forum began with the superb review of the Ocean Commission report by our close colleague and friend VADM (ret.) Paul Gaffney, with whom we have conducted the Monmouth U – Rockefeller U Marine Science and Policy Initiative since 2015.

Quiet Ocean Experiment in Nature magazine

An article in the 11 April 2019 issue of Nature magazine discusses the issue of sound in the ocean and notes the role of the International Quiet Ocean Experiment (IQOE) in studying ocean sound and its effects on marine organisms. PHE has helped conceive and foster the IQOE.

More news is in the March 2019 IQOE Newsletter.

Deep Carbon Observatory abiotic carbon research

A press release summarizes the research of the Deep Carbon Observatory on methane and other hydrocarbons that are not fossil fuels but rather abiotic in origin.  Congratulations to Giuseppe Etiope and others who have led the work.  Tommy Gold would be happy.

Science magazine on eDNA conference report

Science magazine runs a helpful story by Alex Fox on the final report from our 29-30 November 2018 National Conference on Marine eDNA:

The ocean is full of drifting DNA. The United States needs to collect it, researchers say

Also, a good new Japanese research paper is published on eDNA:

Effect of water temperature and fish biomass on environmental DNA shedding, degradation, and size distribution

and in Revelator 27 February 2019

How Do You Protect a Species You Can’t See? For manatees and other hard-to-spot species, the answer may lie in the minute particles of DNA they leave behind as they move through their environments.

Nordhaus Nobel recollection

In December 2018 Jesse Ausubel had the privilege and fun of inclusion in the delegation to Stockholm of William Nordhaus for his receipt of a Nobel prize.  The occasion stimulated Jesse’s recollection, “Getting to know Bill Nordhaus and Climate: On the occasion of his receipt of the Nobel Memorial Prize in Economics for the study of the economics of climate change.
