EU-Klimadienst Copernicus: 21,1 Grad - Weltmeere warm wie nie
The global average sea surface temperature has reached a record high of 21.1 degrees Celsius, according to the EU's Copernicus program. This is the warmest the world's oceans have ever been, and it's happening at an unusual time of year.

The world's oceans have never been warmer than they are now, with a global average sea surface temperature of 21.1 degrees Celsius. This is a concern for climate experts, who are warning of the risks of extreme weather events and coral bleaching.
The world's oceans are getting warmer than they've ever been before. This is because of the way we're treating the Earth, releasing greenhouse gases that make the planet warmer. This can cause really bad weather and hurt the coral reefs that are important for many animals.

The Record-Breaking Sea Surface Temperature
The global average sea surface temperature has reached a record high of 21.1 degrees Celsius, according to the EU's Copernicus program. This is the warmest the world's oceans have ever been, and it's happening at an unusual time of year. In the past, the global sea surface temperature has typically been at its highest in March and April, following the southern hemisphere summer. However, this year's record-breaking temperature has occurred in August, which is a time of year when the global sea surface temperature is usually at its lowest.
The Causes of the Record-Breaking Temperature
The new record is primarily a result of the global warming caused by the release of greenhouse gases, particularly from the burning of fossil fuels. The El Niño phenomenon in the tropical Pacific, which occurs every few years and leads to unusually high temperatures in the region, has also contributed to the record-breaking temperature. According to Stefan Rahmstorf, a climate researcher at the Potsdam Institute for Climate Impact Research, the new record is a further sign of the increasing pressure on the world's oceans. As the temperature rises, so do the risks of extreme weather events and coral bleaching, which can have devastating impacts on coastal communities and ecosystems.
The Impacts of the Record-Breaking Temperature
The record-breaking sea surface temperature is a concern for climate experts, who are warning of the risks of extreme weather events and coral bleaching. The increasing temperature of the oceans is also leading to a decrease in the ability of the oceans to absorb carbon dioxide from the atmosphere, which is a key natural buffer against climate change. This means that the oceans are becoming less effective at mitigating the impacts of climate change, and the risks of extreme weather events and coral bleaching are increasing.
Key points
- The global average sea surface temperature has reached a record high of 21.1 degrees Celsius.
- The record-breaking temperature is a result of the global warming caused by the release of greenhouse gases.
- The El Niño phenomenon has contributed to the record-breaking temperature.
- The increasing temperature of the oceans is leading to a decrease in the ability of the oceans to absorb carbon dioxide from the atmosphere.
- The record-breaking sea surface temperature is a concern for climate experts, who are warning of the risks of extreme weather events and coral bleaching.
If the world's oceans can continue to absorb carbon dioxide from the atmosphere, it could help to mitigate the impacts of climate change. However, the record-breaking sea surface temperature is a concern, and it's essential to take action to reduce greenhouse gas emissions and protect the world's oceans.
The record-breaking sea surface temperature is a sign of the increasing pressure on the world's oceans. If the temperature continues to rise, it could lead to more frequent and severe extreme weather events, as well as coral bleaching, which can have devastating impacts on coastal communities and ecosystems.
