The Marine Debris community aims to contribute to tackling the challenge that marine debris poses to the marine biosphere and, in many ways, to humans. To achieve this mission, the community assesses related societal knowledge needs, assesses existing technologies and identifies needs for new technologies, approaches and best practices, utilizes Earth observations and models to meet those knowledge needs, and assesses options that could mitigate existing marine debris or prevent future debris entering the ocean.
If you are concerned about the plastics and other marine debris in the ocean, join us and help finding pathways to limit what goes into the ocean and to extract form the ocean what is already there.

[Jan. 09, 2026] Ocean Heat Content Sets Another Record in 2025: The analysis published in Advances in Atmospheric Sciences reveals that global ocean warming continued unabated in 2025 in response to increased greenhouse gas concentrations and recent reductions in sulfate aerosols. In the article by Damian Carrington published in The Guardian, John Abraham, a member of the analysis team, is quoted: “Global warming is ocean warming. If you want to know how much the Earth has warmed or how fast we will warm into the future, the answer is in the oceans.”
[Dec. 21, 2025] How to tackle the Human Emergency: In his blog How to become Earth Citizens, Julian Cribb states that “we are now living amid the greatest emergency in humanity’s million-year tenure of the Earth.” He underlines that this emergency comprises ten existential threats that can not be addresses separately: Extinction, Resource Scarcity, Global Poisoning, WMD, Hothouse Earth, Food Scarcity, Uncontrolled Technologies, Pandemics, Overpopulation, Misinformation. “The Council for the Human Future describes this constellation of threats as ‘ the human emergency’.” Cribb emphasizes that “if we want to survive, humans must first agree to survive.” The Council for the Human Future “considers that now is the time for a new kind of human to emerge – the Earth Citizen.” This is what we also aim for here at Place4Us.
