“It’s a stark warning that we are getting closer to this very important limit set by the Paris Agreement,” Copernicus senior climate scientist Nicolas Julien said in an interview. “The global temperature continues to increase. It has at a rapid pace.”


That 1.5 degree temperature mark is important because that’s the warming limit nearly all the countries in the world agreed upon in the 2015 Paris climate agreement, though Julien and other meteorologists have said the threshold won’t be crossed until there’s long-term duration of the extended heat — as much as 20 or 30 years.

“This is more than a statistical oddity and it highlights a continuing shift in our climate,” Copernicus Director Carlo Buontempo said in a statement.

The globe for June 2024 averaged 62 degrees Fahrenheit (16.66 degrees Celsius), which is 1.2 degrees (0.67 Celsius) above the 30-year average for the month, according to Copernicus. It broke the record for hottest June, set a year earlier, by a quarter of a degree (0.14 degrees Celsius) and is the third-hottest of any month recorded in Copernicus records, which goes back to 1940, behind only last July and last August.

It’s not that records are being broken monthly but they are being “shattered by very substantial margins over the past 13 months,” Julien said.

“How bad is this?” asked Texas A&M University climate scientist Andrew Dessler, who wasn’t part of the report. “For the rich and for right now, it’s an expensive inconvenience. For the poor it’s suffering. In the future the amount of wealth you have to have to merely be inconvenienced will increase until most people are suffering.”

Even without hitting the long-term 1.5-degree threshold, “we have seen the consequences of climate change, these extreme climate events,” Julien said — meaning worsening floods, storms, droughts and heat waves.

June’s heat hit extra hard in southeast Europe, Turkey, eastern Canada, the western United States and Mexico, Brazil, northern Siberia, the Middle East, northern Africa and western Antarctica, according to Copernicus. Doctors had to treat thousands of heatstroke victims in Pakistan last month as temperatures hit 117 (47 degrees Celsius).

June was also the 15th straight month that the world’s oceans, more than two-thirds of Earth’s surface, have broken heat records, according to Copernicus data.

Most of this heat is from long-term warming from greenhouse gases emitted by the burning of coal, oil and natural gas, Julien and other meteorologists said. An overwhelming amount of the heat energy trapped by human-caused climate change goes directly into the ocean and those oceans take longer to warm and cool.

The natural cycle of El Ninos and La Ninas, which are warming and cooling of the central Pacific that change weather worldwide, also plays a role. El Ninos tend to spike global temperature records and the strong El Nino that formed last year ended in June.

Another factor is that the air over Atlantic shipping channels is cleaner because of marine shipping regulations that reduce traditional air pollution particles, such as sulfur, that cause a bit of cooling, scientists said. That slightly masks the much larger warming effect of greenhouse gases. That “masking effect got smaller and it would temporarily increase the rate of warming’' that is already caused by greenhouse gases, said Tianle Yuan, a climate scientist for NASA and the University of Maryland Baltimore Campus who led a study on the effects of shipping regulations.


Climate scientist Zeke Hausfather, of the tech company Stripes and the Berkeley Earth climate-monitoring group, said in a post on X that with all six months this year seeing record heat, “that there is an approximately 95% chance that 2024 beats 2023 to be the warmest year since global surface temperature records began in the mid-1800s.”

Copernicus hasn’t computed the odds of that yet, Julien said. The U.S. National Oceanic and Atmospheric Administration last month gave it a 50% chance.

Global daily average temperatures in late June and early July, while still hot, were not as warm as last year, Julien said.

“It is likely, I would say, that July 2024 will be colder than July 2023 and this streak will end,” Julien said. “It’s still not certain. Things can change.”

Andrew Weaver, a climate scientist at the University of Victoria, said the data show Earth is on track for 3 degrees Celsius of warming if emissions aren’t urgently curtailed. And he feared that an end to the streak of record hot months and the arrival of winter’s snows will mean “people will soon forget” about the danger.

“Our world is in crisis,” said University of Wisconsin climate scientist Andrea Dutton. “Perhaps you are feeling that crisis today — those who live in the path of Beryl are experiencing a hurricane that is fueled by an extremely warm ocean that has given rise to a new era of tropical storms that can intensify rapidly into deadly and costly major hurricanes. Even if you are not in crisis today, each temperature record we set means that it is more likely that climate change will bring crisis to your doorstep or to your loved ones.”


Copernicus uses billions of measurements from satellites, ships, aircraft and weather stations around the world and then reanalyzes it with computer simulations. Several other countries’ science agencies — including NOAA and NASA — also come up with monthly climate calculations, but they take longer, go back further in time and don’t use computer simulations.

Earth's more than year-long streak of record-shattering hot months kept on simmering through June, according to the European climate service Copernicus. There's hope that the planet will soon see an end to the record-setting part of the heat streak, but not the climate chaos that has come with it, scientists said.

What is the hottest heat wave recorded? ›

Death Valley National Park — one of the hottest places on the planet — reached a record high temperature of 128 degrees on Saturday, the Los Angeles Times reported. That's just a few degrees shy of the all-time record of 134 degrees set on July 10, 1913.

Why is this heat wave lasting so long? ›

A scientific assessment of the U.S. heat wave estimates that heat this severe and long-lasting was two to four times more likely to occur today because of human-caused climate change than it would have been without it.

How much longer is the average heat wave season now than it was in the 1960s? ›

The average length of the heat wave season across the U.S. cities is 46 days longer now than it was in the 1960s and, in recent years, the average heat wave in major U.S. urban areas has lasted about four days.

What causes this extreme weather heat wave? ›

Causes. Heat waves form when a high pressure area at an altitude of 10,000–25,000 feet (3,000–7,600 metres) strengthens and remains over a region for several days and up to several weeks. This is common in summer in both the Northern and Southern Hemispheres. This is because the jet stream 'follows the sun'.

Is summer of 2024 going to be hot? ›

For its 2024 summer outlook, the almanac states that California will see hot and dry conditions. The almanac forecasts that it will likely be “warm, hot, and muggy” for most of the country. In the Northwest region, as “more seasonable summer temperatures are expected,” it said.

Is there a heatwave coming in 2024? ›

Why is the US having a heat wave? ›

Unusually hot days and heat wave events are a natural part of day-to-day variation in weather. As the Earth's climate warms, however, hotter-than-usual days and nights are becoming more common (see the High and Low Temperatures indicator) and heat waves are expected to last longer and become more frequent and intense.

Why is the heat getting worse? ›

Scientists say the increase is driven by greenhouse gas emissions that trap heat in Earth's atmosphere. That, in turn, fuels more extreme weather. ​​"Most of the warming occurred in the past 40 years, with the seven most recent years being the warmest," notes NASA.

How long will a heat wave last? ›

Are summers getting hotter? ›

But is very clear that—with global warming now heating the world to 1.2 degrees Celsius above its average in the late 19th century—summers are dramatically ramping up. “There's no question that summers have changed,” says Kristie Ebi, an epidemiologist who specializes in heat-related health risks.

Why is the world so hot right now? ›

Climate change. By far the biggest contributor to the overall +1.7°C global temperature anomaly is human-caused climate change. Overall, humanity's effect on the climate has been a global warming of about 1.2°C. The record-high rate of greenhouse gas emissions means we should expect global warming to accelerate too.
