Healthy marine ecosystems are crucial for people’s livelihoods and food production. Global climate stressors, such as warming and ocean acidification, can drastically impact the structure and function of marine food webs, diminishing the production of goods and services. Our ability to predict how future food webs will respond to a changing environment is limited by our understanding of species responses to climate change, which are often tested in isolation or in simplified experimental designs.

Noble gases trapped in ice cores are used to show that the mean global ocean temperature increased by 2.6 degrees Celsius over the last glacial transition and is closely correlated with Antarctic temperature.

Present-day mass redistribution increases the total ocean mass and, on average, causes the ocean bottom to subside elastically. Therefore, barystatic sea level rise is larger than the resulting global mean geocentric sea level rise, observed by satellite altimetry and GPS-corrected tide gauges. We use realistic estimates of mass redistribution from ice mass loss and land water storage to quantify the resulting ocean bottom deformation and its effect on global and regional ocean volume change estimates.

If you imagine fish as birds of the ocean, they fly through forests and over fields which grow in the rich soil of the continental shelf.

The space agencies of China and France recently announced that they are joining forces to launch a brand new satellite into orbit to improve the understanding and prediction of ocean storms and cyc

The current period of climate change may be unparalleled over the last 100 million years, warn scientists who discovered a flaw in the way past ocean temperatures have been estimated up to now.

The history of the Earth system is a story of change. Some changes are gradual and benign, but others, especially those associated with catastrophic mass extinction, are relatively abrupt and destructive. What sets one group apart from the other? Here, I hypothesize that perturbations of Earth’s carbon cycle lead to mass extinction if they exceed either a critical rate at long time scales or a critical size at short time scales. By analyzing 31 carbon isotopic events during the past 542 million years, I identify the critical rate with a limit imposed by mass conservation.

Something needs to be done to check it: expert

It is possible to trigger ocean oxygen depletion, choking the world’s seas.

This policy brief, prepared by SIWI and Alliance for Global Water Adaptation (AGWA), is a contribution to the discussions and activities at UNFCCC meetings in order to improve understanding and application of gender and water knowledge in the climate arena.
