Has the 1.5°C target set out in the Paris Agreement been breached?
Last month was the fourth-warmest July on record in Europe, with average temperatures reaching 21.12°C, 1.30°C above the 1991-2020 average for July.
"There were some regional contrasts, as is often the case in Europe," Julien Nicolas, Senior Scientist at Copernicus, told Euronews. The month started extremely hot in most of Europe, particularly the western part. "As the month progressed, temperatures cooled and conditions became wetter in the western and central parts of Europe."
The anomalies which stood out in July were the much-above-average temperatures recorded in Scandinavia, where temperatures reached 30°C for several weeks. "That's quite significant, and is not the weather we would expect to persist at these latitudes."
Meanwhile, in Turkey, the temperature reached 50°C.
Long-term warming trend
One of the report's key findings noted that, globally, July 2025 was 1.25°C above the estimated 1850-1900 average used to define the pre-industrial level. In 21 of the past 25 months, the average global temperature was 1.5°C or more above this level.
This begs the question: Does this mean the landmark Paris Agreement, which is ratified by all EU member states and aims to limit the long-term average temperature increase to 1.5°C above the pre-industrial level, has failed?
"That's a debated question at the moment," Nicolas said. "I think one must remember that the Paris agreement refers to a long-term average temperature of 1.5°C that shouldn't be exceeded to avoid the most catastrophic and irreversible consequences of climate change. What we have seen over the past couple of years are temporary breaches of this limit."
He explained that generally, the long-term average will only be considered exceeded when the level has been breached over a 20-year average—the length of time that is considered apt to characterise the climate and smooth out the natural fluctuation of the global temperature.
"Once we have reached this 20-year average of global temperatures rising above the 1.5°C, that's when we can consider that we have exceeded the limit of the Paris Agreement," Nicolas added.
The recent model predictions show that this limit might be reached as soon as 2030. "This is just a few years away. But we haven't reached it yet."
Copernicus scientists noted that the recent streak of global temperature records is over—for now. There will be periods of "cooling", as in July 2025, when the average global temperature was "just" 1.25°C above the estimated 1850-1900 average. This is due to natural fluctuations in the climate.
"But that comes on top of the long-term warming trend that is directly related to the accumulation of greenhouse gases in the atmosphere." In other words, climate change hasn't stopped.
Catastrophic effects
To this point, climate scientists regularly point to the effects of a warming world that are being witnessed in all corners of Europe. In July, fatal flash flooding hit parts of Romania, while an extreme heatwave claimed lives on Italy's beaches.
"One thing to remember is that these extreme climate events didn't start two years ago; we have seen them happening for many years," said Nicolas. "We have seen the consequences of climate change. This also includes the melting of glaciers and sea level rise. But the fact that global average temperatures reached record levels makes these extreme climate events more likely."
He emphasised that this long-term warming trend and its catastrophic implications won't stop anytime soon, as long as greenhouse gases continue to accumulate in the atmosphere.
For this reason, climate scientists continue to press for measures to counter this trend. "We see the urgency of continuing climate actions to cut greenhouse gas emissions globally. And that clearly is something that shouldn't stop," Nicolas said.
This is true even if the 1.5°C limit set by the Paris Climate Agreement is exceeded. "We must continue doing everything we can to cut greenhouse gas emissions, because as we often say, every fraction of a degree matters."
It is in this context that various civil society organisations and academia have voiced concern for and opposition to the European Commission proposing to allow international carbon offsets to help meet the EU's 2040 climate targets.
This move raised concerns about outsourcing the emission reduction actions, which critics say effectively waters down climate ambitions.

Want to keep your brain sharp in old age? Helping others could be key
'What goes around comes around' may be just an expression, but helping others could have significant benefits for our brains as we age, a new study has found. Middle-aged and older adults who regularly help people they do not live with experience considerably slower cognitive decline than those who do not help others, according to the study, which was published in the journal Social Science and Medicine. Researchers analysed data from more than 30,000 adults aged 51 or older in the United States whose brain health was tracked from 1998 to 2020. Scientists explored how both formal helping, such as volunteering in an organisation, and informal helping, like assisting a neighbour or a friend outside the house, affect cognitive wellbeing and health over time. The study found that both formal and informal helping were associated with higher levels of cognitive function and a slower cognitive decline later in life, whereas withdrawing from these activities was linked to poorer cognitive ability. 'Informal helping is sometimes assumed to offer fewer health benefits due to its lack of social recognition,' Sae Hwang Han, an assistant professor of human development and family sciences at the University of Texas and one of the study's authors, said in a statement. 'It was a pleasant surprise to find that it provides cognitive benefits comparable to formal volunteering,' he added. According to the study, older adults did not need to commit much time to helping others to see the cognitive benefits. Even moderate engagement of two to four hours per week was linked to substantial advantages for brain health. 'The cognitive benefits of helping others weren't just short-term boosts but cumulative over time with sustained engagement,' Han said. However, the study also has some limitations. It did not provide details on the exact ways that people volunteered, relied on self-reported data, and cannot claim with certainty a cause-and-effect relationship between volunteering and brain health. Even so, the results are in line with previous findings. Earlier research has suggested a positive link between cognitive performance and volunteering, with some studies even highlighting that the benefits are particularly significant for women. Notably, however, volunteering opportunities often target young people. In the European Union, official regional programmes like the European Solidarity Corps are open to those aged 18 to 30 to contribute to social projects across the bloc. No such programme exists for middle-aged and older adults. In 2021, the European Commission recommended that older adults volunteer in its Green Paper on Ageing, but the focus was on intergenerational cooperation and enhanced self-esteem, not cognitive health. Han said the latest findings suggest older adults should stay active members of their communities as long as possible, for their own sake as much as others'. 'This suggests the importance of keeping older adults engaged in some form of helping for as long as possible, with appropriate supports and accommodations in place,' he said.

How many tropical nights have occurred across Europe?
Europe saw the second-highest number of tropical nights on record in 2024 due to climate change, according to the EU's Copernicus service (C3S). A tropical night is defined as a night when the temperature does not drop below 20C. Over the past few decades, the number of tropical nights in Europe has been rising. The rate of warming is more than double the global average over the last 30 years. The southeast of Europe was particularly affected, with some areas of southern Greece experiencing up to 55 more tropical nights than average. Much of Italy saw up to 50 additional tropical nights, while western Turkey recorded up to 40 more. Some regions in Croatia, Serbia, Hungary, Romania, and Bulgaria experienced up to 35 extra tropical nights. In June and early July of 2025, many areas across the European continent experienced more tropical nights than usual for that period. Parts of Spain, for example, recorded up to 24 tropical nights in June, which is 18 more than the average for that month. Linked to the marine heatwave in the Mediterranean Sea, coastal areas around the Mediterranean Sea saw around 10 to 15 tropical nights, despite typically not experiencing any in June. A World Weather Attribution study has also found that Sweden endured 10 consecutive tropical nights due to a prolonged Nordic heatwave. "Nighttime temperatures have been made about 2C hotter than they would have been without human-caused climate change, and around 33 times more likely," the report stated. "After a further 1.3C of warming, nighttime temperatures are projected to warm by a further 1.7C, with temperatures like those recorded in 2025 a further seven times more likely to occur. " How do tropical nights affect your health? Tropical nights might mean a sleepless, sweaty time in bed, when bed sheets cling to skin and opening windows brings no respite. Besides being uncomfortable, high nighttime temperatures can pose health risks, as the body may not recover from daytime heat stress as it normally would. Symptoms of heat stress include increased heart rate, dizziness, and, in severe cases, heat stroke. There were estimated to be around 47,700 heat-related deaths in Europe in 2023, and around 61,700 in 2022.

Europe says it leads the world in Earth Observation. But what is it?
The heavy-lift launcher, developed over a decade by the European Space Agency (ESA) and ArianeGroup, was launched from Europe's Spaceport in Kourou, French Guiana this Tuesday. After just over an hour, the satellite separated from the rocket and began its journey around the Earth. With this new satellite the EU strengthens its position as a leader in Earth observation, according to Andrius Kubilius, EU Commissioner for Defence and Space. What is Earth observation and why this matters? Earth observation is the process of gathering information about our planet's physical, chemical and biological systems – Europe relies on the Sentinel satellites from the Copernicus programme managed by the European Space Agency. From measuring Arctic ice melt to mapping deforestation, the technology allows scientists to see changes in the environment with great precision. The new satellite, Sentinel-5A, will be operated by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and is designed to deliver high-quality data for forecasting extreme weather, tracking greenhouse gas emissions and monitoring ocean temperatures. 'Extreme weather has cost Europe hundreds of billions of euros and tens of thousands of lives over the past 40 years,' said EUMETSAT Director-General Phil Evans to Euronews. This launch is a 'major step forward in giving national weather services sharper tools to save lives, protect property, and build resilience against the climate crisis.' Timo Pesonen, Commission Director General for Defence Industry and Space said on social media his hope that the new Sentinel satellite will participate to track air quality and emissions worldwide to support EU policies like the Methane Strategy and Air quality Directive. Europe's independent path to space The satellites programme Copernicus is the world's most advanced fleet of Earth observation – however the EU lacked its own capacity to send those satellites into space. By coupling world-class satellite technology with independent launch capacity, Europe is positioning itself as a leader in both the science and infrastructure of Earth observation. Until now, Europe's space ambitions faced this practical challenge to get satellites into orbit without depending on outside players. With Russia's Soyuz rockets no longer an option, the continent had become increasingly reliant on SpaceX, Elon Musk's US-based company, for launches – an embarrassing ally.
