Rising Temperatures, Rising Stakes: Climate Change and Global Sports

In July 2023, the FIFA Women’s World Cup in New Zealand and Australia encountered unusually warm winter weather. This disrupted training schedules and raised concerns about player performance. Organisers had expected a temperate climate, but heatwaves and erratic weather patterns complicated the tournament's planning, demonstrating how climate change is reshaping global sports events.

Extreme weather frequently impacts sports. In August 2022, the US Open recorded court-surface temperatures exceeding 37°C (98.6°F), leading to mid-match medical interventions for dehydrated players. Climate scientists have warned since the 2018 IPCC Special Report on Global Warming of 1.5°C that heatwaves are becoming more common due to human-induced climate change.

For major events like the Olympics or FIFA World Cups, the stakes extend beyond the field. Venue construction, international travel, and energy-intensive broadcasting significantly contribute to environmental degradation. During the 2022 FIFA World Cup in Qatar, carbon emissions reached 3.6 million tonnes of CO₂e—equivalent to Namibia's annual emissions, according to FIFA's reports. Critics argue these figures may understate the reality due to inconsistencies in carbon accounting.

“Sports events are microcosms of global environmental challenges,” said Dr. Madeleine Orr, a leading researcher on sport ecology at Loughborough University. “From infrastructure to operations, hosting nations must recalibrate priorities to meet climate imperatives.” She also highlighted the paradox of carbon offsets often cited by organisers. “Net-zero pledges mean little if actions don’t align with timelines set by science,” she added.

Rising temperatures are testing athlete safety thresholds. Broadcasters and sponsors have historically prioritised viewer schedules over environmental constraints. During the 2014 World Cup in Brazil, hydration breaks were introduced mid-game as pitch-side temperatures reached 39°C (102°F). This was unprecedented in FIFA history—a signal of what lies ahead. A recent report from the Union of Concerned Scientists projects that days exceeding safe temperatures for outdoor sports could double in temperate regions by 2050 if global emissions trends persist.

Grassroots sports face similar risks. Community-run events, especially marathons and cycling races, are increasingly vulnerable to cancellations due to flooding or wildfire smoke. In September 2023, the Boulderthon marathon in Colorado was cancelled due to poor air quality, highlighting these challenges. Small-scale organisers often lack the resilience funding or insurance options available to global tournaments, leaving local economies exposed when events are cancelled.

Sustainability strategies are emerging unevenly across the sector. Innovations like zero-emission venues, such as the Climate Pledge Arena in Seattle, offer glimpses of potential. Opened in October 2021, the arena integrates renewable energy systems and water management to eliminate reliance on fossil fuels. However, these measures remain exceptions. According to the Green Sports Alliance, only 15% of major venues worldwide currently operate under stringent sustainability criteria.

For event hosts, equitable access to adaptation resources is a pressing concern. Wealthier nations and franchise-backed leagues can absorb the costs of sustainable retrofitting, while smaller economies struggle. The African Union of Broadcasting has raised concerns about the rising costs of sustainable broadcasting technologies, which often exclude developing-world broadcasters from large-scale sports events. “We risk turning sustainability into an exclusivity club,” noted Oluwasegun Adebayo, a Nigerian sports commentator.

Player advocacy groups are increasingly vocal about climate impacts. In April 2023, the World Players Association issued its first climate demands manifesto, urging international federations to enforce heat-protection protocols and transition to climate-resilient infrastructure by 2035. Players like tennis star Dominic Thiem have begun championing causes, partnering with NGOs to fund offset projects. Critics argue such initiatives offload systemic responsibilities onto personal goodwill.

The broader question is whether sports governing bodies can shift from reactive to proactive environmental stewardship. The International Olympic Committee (IOC) announced its commitment to a net-zero carbon future by 2030 but has faced scrutiny for inconsistencies in carbon accounting during the Tokyo 2020 Games. Transparency and third-party audits remain rare, raising questions about accountability.

In Lagos, Nigeria, sports enthusiasts like 27-year-old Damilola Akinyemi are closely watching the debate. “Football is everything here. But we’ve seen pitch closures for flooding three times in one season. If these problems get worse, it’s not just the athletes who lose—it’s the entire community,” she said. Akinyemi highlighted local initiatives to plant shade-providing trees around amateur football fields, demonstrating how community-led action can complement institutional efforts.

Climate adaptation is now a critical issue for sports. Without accelerated reforms, the viability of outdoor events in many regions could collapse within decades. The industry must act decisively to avoid dire consequences.

As the 2026 FIFA World Cup approaches, organisers face a litmus test. Beyond the spectacle of a 48-team format lies the reality of what climate-conscious sports programming truly entails. Will this tournament signal an era of meaningful reform? Or will it simply replicate the unsustainable status quo? Answers will emerge not only on the pitch but across the supply chains and communities enabling the games.

The costs of inaction will run deeper than tournament budgets.
