The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
The world’s oceans rose to the highest temperatures ever recorded by far in 2017, scientists have warned. Research by a team of Chinese experts found the upper 2,000m of ocean water were far warmer in 2017 than the previous hottest year in 2015. The findings, published in the journal Advances …
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 …
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 …
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.
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. Just as on land, it's Earth teeming with roots and creatures that form the base of the sea's food web and upon which its …
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 cyclones. The China-France Oceanography Satellite (CFOSAT), the first satellite to have been constructed as a partnership between the …
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. According to the methodology widely used by the scientific community, the temperature of the ocean depths and …
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 …
Something needs to be done to check it: expert The oceans around the globe have become the dumping ground for everything and huge quantity of plastic is dumped into it. This is already a major ecological problem and the aquatic life is threatened. Something needs to be done to arrest …
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. The interface between freshwater and oceans captures the vital development …
It is possible to trigger ocean oxygen depletion, choking the world’s seas. The suffocation zone – the region of the deep sea floor that is now oxygen-depleted – could double in a century, because of human-triggered climate change and other actions. But don’t panic: the last time the oceans lost …
Growing international and national focus on quantitatively measuring and improving ocean health has increased the need for comprehensive, scientific, and repeated indicators to track progress towards achieving policy and societal goals. The Ocean Health Index (OHI) is one of the few indicators available for this purpose. Here we present results …
While global ocean health has remained relatively stable over the past five years, individual countries have seen changes, according to a study published July 5, 2017 in the open-access journal PLOS ONE by Benjamin Halpern from University of California Santa Barbara, USA and colleagues. The Ocean Health Index has been …
As humans put ever more heat-trapping gases into the atmosphere, the Earth heats up. These are the basics of global warming. But where does the heat go? How much extra heat is there? And how accurate are our measurements? These are questions that climate scientists ask. If we can answer …
Fears that progress towards some Sustainable Development Goals (SDGs) may undermine achievements in others are largely unfounded, a science-based analysis of their interactions has concluded. The SDGs were designed with linkages between the health, environmental, and social-economic aspects of development in mind. But it is unclear whether they will reinforce …
As world leaders criticise the United States for pulling out of the Paris climate agreement, scientists are trying to work out exactly what a warmer world will mean. That includes researchers in Senegal, who are making precise measurements of the ocean to try to predict how it will change. And …
President Ali Bongo Ondimba announced to the UN Ocean Conference that the government of Gabon has created a network of marine protected areas the size of Costa Rica. Gabon pledges ‘massive’ protected network for oceans The network of marine protected areas covers some 53,000 square kilometers (20,463 square miles) of …
On World Oceans Day, 8 June, UNESCO will present the first ever global stock-taking of the oceanographic sciences at the United Nations' Ocean Conference, at the UN in New York from 5 to 9 June. Other UNESCO events at the conference will focus on underwater cultural heritage and marine World …
Global average temperatures could pass 1.5C above pre-industrial levels within the next decade, new projections suggest. The timing of when we actually hit the 1.5C threshold will depend heavily on a natural cycle in the Pacific Ocean, the study finds, which can either dampen or accelerate global temperature rise. The …
Fungi have recently been found to comprise a significant part of the deep biosphere in oceanic sediments and crustal rocks. Fossils occupying fractures and pores in Phanerozoic volcanics indicate that this habitat is at least 400 million years old, but its origin may be considerably older. A 2.4-billion-year-old basalt from …
