COP26 is the 2021 United Nations climate change conference

For nearly three decades the UN has been bringing together almost every country on earth for global climate summits – called COPs – which stands for ‘Conference of the Parties’. In that time climate change has gone from being a fringe issue to a global priority. Specifically part of the COP conference is focused on our oceans and seas. Part of the COP discussions includes the ‘Ocean Decade’.

What is the Ocean Decade?

The Ocean Decade provides a ‘once-in a-lifetime’ opportunity to create a new foundation across the
science-policy interface to strengthen the management of the ocean and coasts for the benefit of humanity and to mitigate the impacts of climate change. The Ocean Decade Implementation Plan outlines ten Decade Challenges, representing the most immediate and pressing needs of the Decade.

New study on phytoplankton changes and climate from 1850-2100

Climate change is causing significant shifts in the phenology of phytoplankton communities, but current Earth System Models (ESMs) do not take into account the various phenotypes and trait groups that result from evolutionary strategies. A new study has used a species-based modelling approach, combined with large-scale plankton observations, to investigate past, contemporary, and future phenological […]

Phytoplankton and climate change in the North Atlantic

A team of UK and French scientists have shown dramatic changes in the abundance of phytoplankton in the North Atlantic over the last 60 years driven primarily by climate variability and North Atlantic warming. In particular, the scientists focused on the important group of phytoplankton collectively known as diatoms. This major phytoplankton group contributes approximately […]

Deep ocean warming as climate changes

Much of the “excess heat” stored in the subtropical North Atlantic is in the deep ocean (below 700m), new research suggests. Oceans have absorbed about 90% of warming caused by humans. The study found that in the subtropical North Atlantic (25°N), 62% of the warming from 1850-2018 is held in the deep ocean. The researchers […]

Warming oceans are getting louder

FASTER SOUND TRANSMISSION IN THE OCEANS DUE TO CLIMATE CHANGE WILL CHANGE THE UNDERWATER SOUNDSCAPE MARINE ORGANISMS RELY ON FOR SURVIVAL AND REPRODUCTION IN COMING DECADES. Climate change will significantly alter how sound travels underwater, potentially affecting natural soundscapes as well as accentuating human-generated noise, according to a new global study that identified future ocean […]

When variations in Earth’s orbit drive Phytoplankton evolution

Coccolithophores are microscopic algae that form tiny limestone plates, called coccoliths, around their single cells. The shape and size of coccoliths varies according to the species. After their death, coccolithophores sink to the bottom of the ocean and their coccoliths accumulate in sediments, which faithfully record the detailed evolution of these organisms over geological time. […]
