Another record has fallen
Another record has fallen. The month of August 2026 is now tied for the hottest month ever recorded by scientists, a finding that officially puts it on a par with the previous record holder from July 2023. The data is final. The global average temperature was 1.65 degrees Celsius above pre-industrial levels, according to the European Union’s Copernicus Climate Change Service. They announced the new figures on Thursday. The heat was exceptional. It was also familiar.
This specific figure, 1.65 degrees, is measured against the average global temperature between the years 1850 and 1900. That period is the benchmark. It acts as a proxy for the climate before the widespread use of fossil fuels that began with the industrial revolution. Reaching 1.65 degrees above that historical average represents a significant departure from the long term norm, putting the planet into a temperature range not experienced in human history. The reading for August confirms the planet has once again reached this specific point of heating. It happened before. It has happened again.
This was a tie. The record for the single hottest month was not broken, it was equalled. For a second time, the global climate system has sustained a monthly average temperature at this level. There is no ambiguity in the data. July 2023 was the first month to reach this height, and now August 2026 has followed. The two months sit together at the top of the global temperature charts. Nothing has been recorded hotter. The world has now had two such months. They stand apart from all others in the modern observational record.
The declaration comes from an institution designed for this purpose. The Copernicus Climate Change Service operates as Europe’s primary authority on climate monitoring. Its scientists compile and analyse billions of measurements taken from satellites, ships, aircraft and weather stations located all around the world. This vast quantity of information is processed to create a comprehensive and reliable picture of the Earth's climate. The service’s conclusion that August 2026 tied with July 2023 is the result of that rigorous process. It is a statement of scientific fact.
Two forces are driving the heat
Scientists identify two principal causes. They are not separate. They are acting in concert. One is a long term process of planetary warming driven by human activity over many decades. The other is a powerful, temporary and entirely natural weather pattern known as El Niño. This combination is pushing global temperatures into uncharted territory. The August record was a product of these two forces working together. One is constant. The other is cyclical. Their effects have merged. This is the result.
The background warming is the foundation for this new record. The planet is hotter than it was a century ago. This is a simple fact. The persistent accumulation of greenhouse gases in the atmosphere has raised the world’s baseline temperature, meaning that every day, every month and every year now starts from a higher thermal point than it used to. It is this elevated platform that allows natural weather phenomena to produce such extreme outcomes. Climate change has loaded the dice. It creates the conditions for new records to be set. This is the persistent pressure. It is always there.
The second force is El Niño. This is a recurring climate pattern. It involves the unusual warming of surface waters in the eastern tropical Pacific Ocean. While it is centred there, its influence is global, altering weather patterns far from its source. The current El Niño event is a significant one. Its influence is rising. The sources for the August 2026 data are clear on a critical point. The event has not yet reached its full strength. It is still intensifying. This means its warming effect on the planet is still growing and has not reached its maximum.
The peak is yet to come. The record temperatures of August were achieved while this powerful natural driver was still in its development phase. Scientists state that the El Niño system will continue to strengthen for several more months. Its full impact is expected later in 2026 and into early 2027. This suggests that the current record, extreme as it is, may not stand for long. The same forces that produced the August heat are still building. The temporary warming from the Pacific is being added on top of the permanent warming from climate change, a potent formula for breaking records that were themselves only set recently. The system has more heat to give.
The people who measure the heat
The numbers come from one place. The Copernicus Climate Change Service. It is an arm of the European Union’s space programme, a vast and complex organisation dedicated to observing the planet. Its job is to provide authoritative data on the Earth’s climate. It is not an advocacy group. It is a data service. The information it provides is used by governments, scientists, and the public around the world. Its sole function is measurement.
How does it work? The service fuses powerful computer models with raw observations. Billions of data points are processed each month. These observations come from an array of instruments. Satellites orbiting high above the Earth provide a global perspective on atmospheric conditions and surface temperatures. Weather stations on land offer detailed local readings. Information also comes from ships at sea and from floating buoys scattered across the oceans. All this information, a flood of numbers from thousands of sources, is assimilated into a single, coherent analysis. The process, known as reanalysis, uses the laws of physics to stitch the observations together, creating a complete and physically consistent picture of the planet’s climate for a given month. It is a monumental task. The result is a trusted dataset.
The August report was not just about air temperature. There was more. Copernicus noted another record. The surface of the sea was also hotter than ever before for the month of August. This matters. The oceans absorb the vast majority of the extra heat trapped by greenhouse gases, acting as a huge thermal buffer for the planet. Record sea temperatures are a sign of immense stress on the marine ecosystem and a source of energy for extreme weather events. They show that the heating is not a superficial phenomenon. It penetrates deep into the planetary system. The ocean has a long memory. The heat it absorbs today will influence the climate for decades to come.
This is the work of the Copernicus service. It measures. It reports. The service itself does not create policy. It does not campaign. It simply holds up a mirror to the planet, reflecting the physical state of the global climate system with increasing precision every month. The data from August 2026, including the 1.65 Celsius figure and the record ocean heat, comes from this rigorous, systematic process. It is not an estimate. It is a measurement.
This is part of a sequence
August was not an island. It was part of a chain. The record heat did not arrive from nowhere, appearing suddenly in a single month of shocking temperatures before disappearing again. It was the latest marker in a progression. A run of extreme heat that started in May. It continued through June. It intensified in July. By the time August arrived, the pattern was already set, a baseline of warmth that had been building for an entire season across the northern hemisphere. The numbers from the Copernicus Climate Change Service simply confirmed what was already being experienced. The heat was persistent. It was relentless. The record was the end of a long, hot road.
This sequence extends beyond the summer of 2026. August was not a new, unique record holder. It is a joint winner. It shares the title of hottest month ever recorded with July 2023, a fact confirmed by the European Union’s Copernicus climate service. The peak has now been reached twice. The absolute zenith of global heat, a figure set in 2023 that was itself an astonishing outlier, has now been equalled by a month in 2026. The extraordinary is becoming repeatable. Climatological records historically stood for decades, high watermarks that were surpassed only rarely, during a severe confluence of long term warming and powerful natural weather patterns. That is not the pattern today. Today is different. Records are set. They are matched. They are broken again. The timeframe between them appears to be shortening.
The pattern is not confined to the air. It is also found in the ocean. The August report from Copernicus contained a second, stark finding. Global sea surface temperatures reached their highest level on record for the month of August. Another record was broken. Another part of the system is showing extreme stress. This is significant. The immense volume of the world's seas means they absorb and store vast quantities of energy, warming and cooling far more slowly than the atmosphere. A sequence of record breaking ocean temperatures, running in parallel to the atmospheric records, suggests a more fundamental and persistent shift in the planet's energy balance. It is not just the weather. It is the climate itself. Two separate datasets tell the same story. The world is warming.
Perhaps the most significant detail in this sequence is not what has already happened, but what it suggests is coming next. The run of extreme heat, from May through to the record tying warmth of August, occurred under a specific set of circumstances. It happened before the El Niño weather pattern driving much of the immediate temperature spike had reached its maximum intensity. This is a crucial detail. The full force of this recurring, natural warming phenomenon has not yet been unleashed upon the global climate system. Its peak is still months away. The world matched its all time monthly heat record without the primary short term driver even being at full power. That is the context. This combination, a strong and relentless underlying warming trend from climate change with a strengthening El Niño event layered on top, creates the conditions for the pattern to accelerate. The sequence is not over. It is building. Scientists widely expect the greatest impact of El Niño on global average temperatures to be felt later, towards the end of 2026 and into early 2027. August was a record. It might be a temporary one.
What the science predicts
The August record will not last. This is the consensus. The conditions that created it are intensifying, pointing towards even higher global temperatures in the months ahead. At the centre of these predictions is a single number. That number is 1.5. The August average temperature was 1.65 degrees Celsius above the pre-industrial average. It breached the symbolic 1.5C threshold that nations agreed to in the Paris Agreement as a guardrail for long term warming. This was a temporary breach. A single month does not represent a permanent shift of the entire climate system. Climate scientists are careful to make this distinction, separating the long term average from a short term spike. But it is a distinction with very little comfort. It has happened. The barrier has been broken.
This temporary breach is significant because of its timing. It occurred months before the El Niño weather pattern is expected to reach its maximum strength. El Niño is a natural phenomenon. It involves the warming of vast stretches of the eastern Pacific Ocean, a process which releases an enormous quantity of heat into the atmosphere. This has a direct impact on global temperatures. It pushes them upwards. The current El Niño event is still developing. Its full power has not yet been felt. The peak impact on global air temperatures characteristically lags behind the peak warming of the ocean itself, meaning the world will feel the greatest effect towards the end of 2026 and into the start of 2027. August matched the hottest month ever recorded while this powerful, natural engine of global heat was still in a lower gear. It is now accelerating. The implications are clear.
What happens next is a matter of scientific expectation. Not speculation. The combination of a strong El Niño event layered on top of the steady, relentless background warming caused by human activity creates the perfect conditions for breaking heat records. It is almost inevitable. Scientists now widely predict that 2026 or 2027 will go on to become the hottest year ever measured, surpassing previous records. The monthly records for heat set in July 2023 and August 2026 are therefore unlikely to survive the coming winter and spring. Another series of hottest ever months is the probable outcome. This makes further crossings of the 1.5C line a near certainty. The world is already hovering just below this line due to baseline global warming. El Niño provides the final push needed to go over it, again and again.
Crossing this line, even for a few months, is a profound change. It is a warning. The 1.5C target has, for years, been an abstract concept discussed in policy documents and at climate summits. It was a future to be avoided. A line on a graph. The events of August 2026 made it a present reality, a measured fact reported by the EU’s Copernicus Climate Change Service. It demonstrated that the climate has reached a point where natural variability alone is enough to push the world into this critical territory. The safety buffer has eroded. It is gone. This is what a temporary breach means. It is a real world demonstration of what the planet looks like at 1.5C of warming. It is a preview.
Eventually, this El Niño will end. The cycle will turn, the Pacific will cool, and a countervailing La Niña period may follow. Global temperatures will likely dip in response. They will probably fall back below the 1.5C line for a time. That is the nature of the cycle. But the crucial point is the baseline to which they will fall. It will be a higher baseline than the one that existed before this El Niño began. Each peak gets higher, and each trough gets shallower. This is the signature of long term climate change. The temporary breaches of 1.5C in 2026 are a glimpse of a future where such temperatures are not temporary. They are the new normal. This is what the science shows. It is a brief look at the climate that is currently being locked in for the long term. A permanent state of affairs.
