Extreme heat, deadly temperatures and destructive wildfires are intensifying concerns about the world’s changing climate, renewing calls for environmental action and greater attention to the Catholic Church’s teaching on care for creation.
According to Vatican News, July 2026 was the hottest July recorded globally since records began in 1850, tying July 2024. The report cited data from the U.S. National Oceanic and Atmospheric Administration and described widespread consequences as extreme temperatures affected countries across several continents.
Japan experienced its longest recorded streak of temperatures reaching 40°C, or 104°F, while parts of North Africa approached 49°C, or 120°F, according to information cited by Vatican News. Europe recorded its second-warmest July, following repeated heatwaves that contributed to drought and severe wildfire conditions.
France was among the countries hit particularly hard. According to Vatican News, citing an AFP analysis, more than 7,300 excess deaths were recorded in France during historic heatwaves beginning in mid-June.
Wildfires have also swept across parts of Europe, with Belgium, Spain, France, Greece and Italy among the countries battling fires during June and July. Vatican News reported that Europe’s 2026 fire season is becoming the third worst on record, behind 2025 and 2022, based on data from the European Forest Fire Information Service.
The threat could grow considerably in the decades ahead. A study cited by Vatican News projects that wildfires could burn 39% more land in Europe by the end of the century even under a best-case climate scenario. Under a high-emissions scenario in which global temperatures rise 3.6°C above pre-industrial levels, the area burned could nearly triple.
Researchers emphasize that improved fire management can reduce the danger but cannot replace efforts to address the conditions driving higher temperatures.
Maik Billing, an ecosystem researcher at the Potsdam Institute for Climate Impact Research and lead author of a study cited by Vatican News, warned that under continued high emissions, “we still see strong increases in burnt area.”
“Fire management cannot replace climate mitigation,” Billing said.
The growing toll has also prompted renewed warnings from international climate officials. UN Climate Change Executive Secretary Simon Stiell declared in a July 28 statement that “the climate alarm is blazing from every direction.”
Stiell said climate-related disasters have reached “nightmare proportions, as the costs of humanity’s addiction to burning coal, oil and gas keep spiraling upwards.” He called for a faster transition away from fossil fuels, expanded renewable energy and greater protection for communities already experiencing the effects of extreme weather.
For Catholics, the crisis also brings renewed attention to the Church’s teaching that care for creation is inseparable from responsibility toward one’s neighbor, particularly those most vulnerable to environmental harm.
In his 2015 encyclical Laudato si’, Pope Francis called humanity to recognize both the seriousness of environmental degradation and its capacity to respond together.
“Humanity still has the ability to work together in building our common home,” Pope Francis wrote, adding, “Truly, much can be done!”
Pope Leo XIV has continued that appeal. During the “Raising Hope” conference in Castel Gandolfo in October 2025, he reiterated the call for the human family to “seek a sustainable and integral development,” according to Vatican News.
The Church’s approach to environmental stewardship extends beyond individual choices and calls for responsibility throughout society. Pope Leo cited the need for citizens, organizations and governments to work together to protect creation and reduce environmental damage.
As communities confront extreme heat, drought and increasingly destructive fires, the principles expressed in Laudato si’ remain especially relevant: creation is a gift entrusted to humanity, and protecting the common home requires cooperation, prudence and concern for generations yet to come.
