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.
The Earth’s frozen regions have been so severely affected by global warming that it threatens the very foundations of human societies. And it is difficult to reverse this trend.
The ‘little boy’ may sound innocent, but this year’s El Niño is anything but harmless. It is fuelled by the climate crisis and is expected to be the strongest ever recorded.
Achieving the target of a maximum of 1.5 degrees of warming is not enough for the Earth’s ice-covered regions. Warming must be reduced – ideally to below one degree, according to a new report.
Europe must prepare better for global warming, urges the EU. However, the new measures have been met with criticism.
The US has, single-handedly, worsened the outlook for the planet, according to a report by the UN Environment Programme (UNEP). The country’s shift under Donald Trump is the main reason why global warming is set to be worse than feared. No one will be spared, says UNEP Executive Director Inger Andersen.
In four years’ time, several key targets for the world’s wildlife and natural environment are due to be met – but progress is slow. How to achieve the targets set out in the ‘Paris Agreement for Nature’ is the focus as the UN Conference on Biological Diversity convenes for the 17th time.
A growing number of research studies warn that the ocean circulation system Amoc could be approaching a tipping point already this century. Something that would lead to severe cooling in Sweden, and that has prompted the Swedish Meteorological and Hydrological Institute (SMHI) to begin assessing the risks this could pose to society.
This year’s September was the second warmest on record, according to the EU’s Copernicus Climate Service.
Every year, there are usually isolated reports of barrel jellyfish sightings on the Swedish west coast, but this year there have been significantly more sightings than usual. `There’s no doubt it’s a huge number,´ says marine biologist Martin Stjernstedt at Havets hus in Lysekil.
This influx of heat is occurring at the same time as sea levels are rising ever more rapidly and ocean acidification continues, reports the British newspaper The Guardian. The amount of heat is equivalent to 40 times the annual global energy consumption.
The surface of the Pacific Ocean is already at record-breaking temperatures, and the El Niño weather phenomenon appears to be developing into an extremely powerful ‘super’ variant. There is nothing to compare it with, says climate researcher Gustav Strandberg.
Greenland and Antarctica have lost 11.3 trillion tonnes of ice since the 1970s. This has raised global sea levels by more than three centimetres, according to a new study.
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.
