Jacqueline Zünd's "Heat": A Sensory Exploration of Climate Change

"Heat," directed by Swiss filmmaker Jacqueline Zünd, is a documentary that delves into the impacts of global warming through a sensory lens rather than traditional narrative methods. Premiering at the Visions du Réel film festival in Switzerland, the film presents a stark examination of how extreme temperatures are reshaping lives in the United Arab Emirates, Kuwait, and Egypt. Zünd aims to immerse viewers in environments where the wealthy can escape the heat while those serving them endure harsh conditions.

The documentary features a diverse range of characters, including a delivery driver working long hours in oppressive heat, a Kenyan woman employed in a Dubai ice lounge, and a real estate agent who provides food and ice for stray cats. These narratives highlight the inequalities exacerbated by climate change, as the affluent retreat into air-conditioned spaces, leaving vulnerable populations to cope with extreme temperatures.

Zünd faced significant challenges during production, including extreme heat, with temperatures sometimes exceeding 50 degrees Celsius, and restrictions on filming in the region. Access to certain environments was limited, and the crew often worked without formal authorization. Zünd noted that some filming locations, particularly accommodations for workers, were in dire conditions, with many men sharing cramped spaces without adequate cooling.

The film's visual language, developed in collaboration with cinematographer Nicolai von Graevenitz, aims to evoke the sensation of heat through imagery and sound rather than dialogue. Zünd emphasized the importance of translating physical sensations into cinematic experiences, stating, “I always want to translate states visually.” Early footage did not convey the intense heat, prompting a shift in focus towards sound design to enhance the viewer's experience of discomfort without overwhelming them.

Zünd's approach to the documentary reflects a desire to engage audiences who may be fatigued by conventional climate narratives. She expressed that people are “tired of being told what’s happening,” leading her to explore alternative methods of storytelling that resonate on a sensory level. The film opens with real mirages filmed in Egypt, symbolizing the distortion of reality caused by climate change.

"Heat" is produced by Louis Mataré for Lomotion AG in collaboration with Zünd’s Real Film, and is backed by ARTE and SFR (Swiss Radio and Television). The film is set to premiere in the international competition at Visions du Réel on April 20, running until April 26.

While the documentary aims to shed light on pressing climate issues, it has faced scrutiny regarding its portrayal of the working conditions in the Gulf region. Critics may argue that the film's focus on sensory experience could overshadow the urgent need for systemic change in addressing climate inequalities.
