The sea gets warmer – the species die.
It’s not just coral reefs and fish that are threatened as the oceans warm – it’s all life.
Not since an asteroid wiped out the dinosaurs – along with at least half of all other creatures on Earth – has marine life been so vulnerable.
As the oceans get warmer, all habitats are threatened. There are species that do better than others, but all are affected. Biodiversity, the diversity of species, is threatened which in turn will affect us all.
El Niño events are around 36 per cent more intense than they were before industrialisation. And this trend has accelerated over the last four decades.
The average sea-surface temperature has exceeded 21.1 degrees. It has not been this warm for as long as records have been kept. The record was set on 21 August, according to the EU’s Copernicus Climate Change Service, whose data series outside the polar regions dates back to 1979. What stands out is that the temperature […]
The ocean’s remarkable ability to absorb almost all the excess heat we produce is beginning to wane. There are many reasons for this, and the ones that receive the most attention in the media and in research are global warming and the fact that the water is becoming increasingly acidic. But what is also happening is a rapid loss of dissolved oxygen. Put simply, the sea is running out of oxygen. And a sea that is gasping for breath is a cause for concern for the entire planet.
Octopuses appearing off the coast of Scotland and ‘paddling pool’ temperatures of 33 degrees off the coast of Mallorca. For two weeks in July, parts of the Mediterranean were warmer than ever before. The WWA research network has now calculated that such temperatures would have been impossible without human emissions.
Never before have there been so many of the poisonous predatory fish known as the greater weever in the Kattegat. Commercial fishermen see commercial opportunities. But swimmers would rather avoid the creature that has been dubbed the ‘viper of the sea’. In just a few months this year, Danish fishermen have caught 800 tonnes of […]
Western Europe is experiencing its hottest summer to date, and the sea has never been warmer during the month of July.In Western Europe, a persistent high-pressure system has made the period from June to July the hottest on record, according to the EU’s Copernicus Climate Change Service. The heat is exacerbated by dry ground, which […]
Vibrio bacteria have become increasingly common in Swedish waters. However, it is not yet known exactly how common they are or where they are found. Sweden lacks an overall picture of where they are found and who is at risk of becoming seriously ill from them, says researcher Betty Collin. Infections caused by Vibrio bacteria […]
Our carbon dioxide emissions are causing the world’s oceans to become increasingly acidic. Researchers have now discovered unexpected side effects of this in octopuses – their brains are shrinking dramatically. It is well known that, in the long term, ocean acidification could lead to what are essentially catastrophic conditions for many marine organisms. At present, […]
In June, the world’s oceans were warmer than ever before. According to researchers, temperatures may rise further in the coming months.
The information on the new platform http://www.climate.us is based on data from the formerly popular federal website Climate.gov, which was run by NOAA. (National Oceanic and Atmospheric Administration) One of the government agencies that has seen its budget drastically cut since Donald Trump returned to power in January 2025.
Sound is the whale’s most important tool for finding food, navigating and finding a mate. Now, global warming is wreaking havoc in the oceans. As the acoustic landscape changes, whales are forced to move, alter their mating calls – or fall completely silent when hunger takes over.
Scientists and government agencies are closely monitoring developments in the Pacific Ocean. A new El Niño could lead to sharply rising temperatures and global heat records in the coming year.
New research shows that larger warm-blooded fish species, such as sharks and tuna—known as mesotherms—are at risk of overheating as sea temperatures rise.
Over the past 20 years, macroalgae blooms have increased at an unprecedented rate. This is shown by a new study, which warns that the spread could lead to major changes in the ecology of the sea.
År 2025 blev det tredje varmaste året som registrerats. Det slår EU:s klimattjänst Copernicus fast i en ny rapport. För första gången har planetens medeltemperatur legat över 1,5 graders uppvärmning under tre sammanhängande år. En av platserna där det märks som mest är Antarktis.
The Netherlands has failed to protect the inhabitants of the former colony of Bonaire from climate change, according to a ruling by the District Court in The Hague. ‘This gives island states a boost,’ says researcher Björn Ola Linnér.
The costs of climate change almost double if the impact on the oceans is also included in the calculations. ‘If we don't put a price on the damage that climate change causes to the oceans, it will remain invisible to key decision-makers,’ says environmental economist Bernardo Bastien-Olvera.
A British environmental organisation has named 2025 the ‘year of the octopus’ after a record number of octopus sightings in the coastal waters of the archipelago. A mild winter followed by an unusually warm spring is the reason. En mild vinter följd av en ovanligt varm vår är orsaken.
A new study shows that there is a link between rising temperatures and changes in polar bears' DNA. This may help the bears adapt to increasingly challenging environments.
Climate change intensified the recent catastrophic rainfall in Southeast Asia, according to a rapid assessment by the World Weather Attribution (WWA) research network.
Climate change has caused tropical storms to increase in strength. One contributing factor is rising sea temperatures, which can give storms more power and lead to worse consequences for those affected.
The new report from the United Nations Environment Programme, Emissions Gap Report, states that the world has so far failed to slow down climate change sufficiently. For the ocean, this means dying corals, migrating species and even higher temperatures. - Cod may abandon the North Sea and the Baltic Sea altogether, says Kerstin Johannesson, professor of marine ecology at the University of Gothenburg.
Catastrophic and life-threatening floods loom as Category 5 Hurricane Melissa reaches Jamaica. The storm is the strongest on the globe this year – and among the 20 strongest ever to form over the Atlantic.
They have been called a ‘secret weapon’ in the fight against climate change – eelgrass beds and kelp forests in the sea. They can be likened to trees in the sea that bind carbon dioxide 35 times faster than the Amazon rainforest. But they are under threat from human presence, environmental pollution and emissions.
