Hot days or heat waves? Researchers debate how to count deaths from heat
（文章来源：Science）
More than 47,000 Europeans died from heat-related
causes last year, the warmest on record globally, a study
published this month found. The number was surpassed
only by the 60,000 Europeans who died of heat-related
causes in 2022. Another study this month found that the
toll in Europe could triple by the end of the century if
Earth continues to warm to 3°C or 4°C degrees above
preindustrial levels. The numbers, though shocking, almost
certainly understate the toll of hot weather, worsened by
global warming. But scientists aren’t sure how to do better.
Some argue the best way to understand the impact of heat is to track how death rates vary with
fluctuations in temperature, as the European studies did. But others say a truer measure is to rely on
officially declared heat waves and count excess deaths—those above the expected number—each day.
The two kinds of studies “provide answers to different questions, looking at different exposure
metrics,” says environmental epidemiologist Jaime Madrigano of Johns Hopkins University. Seeing how
deaths vary with temperature captures the health effects of gradual warming, whereas focusing on heat
waves highlights the consequences of extreme cases.
The dispute isn’t just academic. Heat waves grab headlines and the attention of policymakers,
spurring them to adopt heat warning systems that urge people to stay indoors or take other precautions.
But some scientists note that just examining heat waves omits the deaths that occur beyond what’s
considered extreme.
“We shouldn’t look at them as two efforts in parallel,” says occupational epidemiologist Barrak
Alahmad of Harvard University. Deaths from heat are increasing “anywhere you put your eye.”
Heat stroke is the most extreme and direct effect of too much time exposed to high temperatures.
But it only accounts for a minority of the toll. Deaths from many other causes also rise, for example
when heat tips someone with an underlying heart condition into a fatal heart attack.
Proponents of using heat waves to measure how temperature increases those risks say these events
are the deadliest, worst-case scenarios, so understanding them is paramount for preparedness. One study
found that 48 people—most certainly an undercount—died during a 2018 heat wave in South Korea and
its severity prompted changes in Seoul’s heat plan, such as opening more cooling centers. Counting
deaths during heat waves also captures the cumulative health impact of multiple hot days in a row, a
nuance that studies focused on daily temperatures can miss.
But limiting the scope of studies to heat waves likely undercounts deaths because there is no
universal definition of a heat wave, says epidemiologist Vijendra Ingole of the U.K. Office for National
Statistics. Heat waves are declared when temperatures exceed the historical average in an area. However,
because of climate change, a hot spell that would once have been considered a heat wave might not be
today, he says—yet remains deadly.
A study that Ingole co-authored in February with Amruta Nori-Sarma, an environmental health
researcher at Boston University, underscored the limitations of the heat wave approach. They estimated a
different number of deaths at various definitions of a heat wave in India, by duration and relative daily
temperatures. They found that even shorter, less intense heat waves not captured by some definitions have
risks similar to longer, more intense ones, including death.
Epidemiologists like Nori-Sarma argue instead for looking at excess deaths on hot days, regardless of
whether they fall within an official heat wave. That approach also allows researchers to zoom in on
specific populations—children, one geographic region, or those with cardiovascular disease—to capture
differences in the impact of heat. Although epidemiologists can still look at deaths in these groups during
a heat wave, Alahmad says those numbers don’t fully reveal the risk.
“Looking at heat waves only … you’re only looking at one slice of the cake,” says Alahmad,
whose research focuses on outdoor workers. The temperatures they experience don’t necessarily meet the
standard definition of a heat wave but can still be a danger given the longer exposure to heat. But
looking at the entire temperature range, “That’s the whole cake,” he says.
A limitation of both approaches is the lack of robust data, especially from hot places in the Global
South. For example, a 2021 study in The Lancet Planetary Health that looked at both heat waves and
daily temperatures suggested that from 2000 to 2019, almost half a million people died annually from
heat. The modeling study was cited in a United Nations call to action last month on extreme heat and
relied on data in the Multi-Country Multi-City Collaborative Research Network, which pools climate and
health data from 53 countries. But the network leaves out countries such as India, which is known for
extreme summer temperatures, and it includes just one African country: South Africa.
In much of Africa, issues such as a decentralized health care system and limited weather stations
mean mortality and weather data might not exist, says Kiswendsida Guigma, a climate scientist with the
Red Cross Red Crescent Climate Center. Without the data, it’s hard to know just how dangerous heat is.
“It’s like a chicken and egg relationship,” he says. Still, heat waves like the one that affected the
Sahel region of Africa in late March—where temperatures hit up to 45°C for five straight days—could be
opportunities for researchers to collect missing data, he says, even leveraging citizen science in remote
places.
Ultimately, it’s likely a combination of the two metrics that will most accurately capture the fatal
consequences of rising global temperatures. “Going toward one side or the other is perfectly fine, it’s
about the interpretation of the findings,” says environmental epidemiologist Ana Maria Vicedo-Cabrera at
the University of Bern, who co-authored the Lancet study.
And both sides emphasize that one fact is not in dispute. “By any metric we look at, by any
definition we choose, by any method that we pick, [mortality] is getting worse,” Alahmad says.

热天还是热浪？研究人员就如何计算高温死亡人数展开辩论
本月发表的一项研究发现，去年有47000 多名欧洲人死于与高温有关的原因，这是全球有记录以来最
温暖的一年。2022 年，只有6 万欧洲人死于与热有关的原因，超过了这一数字。本月的另一项研究发现，
如果地球继续升温到比工业化前水平高3°C 或4°C，到本世纪末，欧洲的死亡人数可能会增加两倍。这些
数字虽然令人震惊，但几乎可以肯定低估了全球变暖加剧的炎热天气造成的损失。但科学家们不确定如何
做得更好。
一些人认为，了解高温影响的最佳方法是追踪死亡率如何随温度波动而变化，正如欧洲的研究所做的
那样。但其他人表示，一个更真实的衡量标准是依靠官方宣布的热浪，并计算每天超出预期的死亡人数。
约翰斯·霍普金斯大学的环境流行病学家Jaime Madrigano 说，这两种研究“为不同的问题提供了答
案，研究了不同的暴露指标”。观察死亡人数如何随温度变化，可以捕捉到逐渐变暖对健康的影响，而关
注热浪则突显了极端病例的后果。
这场争论不仅仅是学术上的。热浪成为头条新闻和政策制定者的关注焦点，促使他们采用高温预警系
统，敦促人们呆在室内或采取其他预防措施。但一些科学家指出，仅仅研究热浪就忽略了发生在极端情况
之外的死亡。
哈佛大学的职业流行病学家Barrak Alahmad 说：“我们不应该把它们看作是两项并行的努力。”。
“无论你把眼睛放在哪里”，死于高温的人数都在增加
中暑是长时间暴露在高温下最极端和最直接的影响。但它只占死亡人数的一小部分。许多其他原因导
致的死亡人数也在上升，例如，当热量使患有潜在心脏病的人患上致命的心脏病发作时。
使用热浪来测量温度如何增加这些风险的支持者表示，这些事件是最致命、最坏的情况，因此了解它
们对于做好准备至关重要。一项研究发现，在2018 年韩国的一次热浪中，有48 人死亡，其中大多数人死
亡人数不足，其严重程度促使首尔的供暖计划发生了变化，例如开设更多的制冷中心。计算热浪期间的死
亡人数还可以捕捉到连续多个炎热天气对健康的累积影响，而专注于每日气温的研究可能会忽略这一细微
差别。
但英国国家统计局的流行病学家Vijendra Ingole 表示，将研究范围限制在热浪可能会低估死亡人数，
因为对热浪没有普遍的定义。当一个地区的温度超过历史平均水平时，就会产生热浪。然而，他说，由于
气候变化，曾经被认为是热浪的热浪可能不会出现在今天，但仍然是致命的。
Ingole 与波士顿大学环境健康研究员Amruta Nori Sarma 在2 月份共同撰写的一项研究强调了热浪方
法的局限性。他们根据持续时间和相对每日温度，对印度不同定义的热浪估计了不同的死亡人数。他们发
现，即使是一些定义没有捕捉到的更短、强度更低的热浪，也有与更长、更强烈的热浪类似的风险，包括
死亡。
诺里·萨尔马等流行病学家主张，无论是否属于官方热浪，都应关注炎热天气下的超额死亡人数。这种
方法还允许研究人员放大特定人群——儿童、一个地理区域或患有心血管疾病的人群——以捕捉热量影响
的差异。尽管流行病学家仍然可以在热浪期间观察这些群体的死亡情况，但Alahmad 表示，这些数字并不
能完全揭示风险。
Alahmad 的研究重点是户外工作者，他说：“只看热浪……你只看到了蛋糕的一块。”。他们所经历
的温度不一定符合热浪的标准定义，但由于暴露在高温下的时间较长，仍然可能存在危险。但纵观整个温
度范围，“这就是整个蛋糕，”他说。
这两种方法的局限性在于缺乏可靠的数据，特别是来自全球南方热点地区的数据。例如，《柳叶刀行
星健康》2021 年的一项研究对热浪和每日气温进行了研究，该研究表明，从2000 年到2019 年，每年有近
50 万人死于高温。上个月，联合国关于极端高温的行动呼吁中引用了这项建模研究，并依赖于多国多城市
合作研究网络的数据，该网络汇集了来自53 个国家的气候和健康数据。但该网络遗漏了以极端夏季气温而
闻名的印度等国家，只包括一个非洲国家：南非。
红十字会与红新月会气候中心的气候科学家Kiswendsida Guigma 表示，在非洲大部分地区，分散的医
疗保健系统和有限的气象站等问题意味着死亡率和天气数据可能不存在。没有这些数据，很难知道高温有
多危险。“这就像鸡和蛋的关系，”他说。尽管如此，他说，像3 月下旬影响非洲萨赫勒地区的热浪——
那里的气温连续五天达到45°C——可能是研究人员收集缺失数据的机会，甚至可以利用偏远地区的公民科
学。
最终，这两个指标的结合很可能最准确地捕捉到全球气温上升的致命后果。伯尔尼大学的环境流行病
学家Ana Maria Vicedo Cabrera 是《柳叶刀》研究的合著者，她说：“走向一边或另一边是完全可以的，
这取决于对研究结果的解释。”。
双方都强调，有一个事实没有争议。Alahmad 说：“根据我们观察的任何指标，根据我们选择的任何
定义，根据我们挑选的任何方法，[死亡率]都在恶化。”。
