📚 How Climate Change Risks Are Disrupting UK School Attendance | 气候变化风险会怎样影响英国学校正常上课
Every school year in the United Kingdom is built on an assumption of 190 statutory teaching days. Climate change is steadily eroding that assumption. Flooded access roads, classrooms above 30 °C, red weather warnings and coastal erosion now interrupt lessons in every region of England, Wales, Scotland and Northern Ireland, and the frequency of such disruption is rising faster than schools can adapt.
英国的每个学年都建立在 190 个法定教学日的假设之上，而气候变化正在逐步侵蚀这一假设。被洪水淹没的通学道路、超过 30 °C 的教室、红色天气预警以及海岸侵蚀，如今在英格兰、威尔士、苏格兰和北爱尔兰的每个地区都在打断教学，而这类干扰出现的频率正快于学校适应能力提升的速度。
1. The Core Question | 核心问题
The exam question behind this topic is simple: how does a change in the physical environment translate into a measurable change in human systems, specifically education? To answer it you must link a climatic hazard to an operational threshold, then to a consequence for pupils.
这一选题背后的考试问题很简单：自然环境的变化如何转化为人类系统（尤其是教育系统）中可测量的变化？要回答它，你必须把气候灾害与运行门槛联系起来，再与学生的后果联系起来。
The chain of reasoning runs as follows: a hazard event (flood, heatwave, storm) occurs with increasing frequency or magnitude; a school crosses a physical or safety threshold; the school closes, opens late or sends pupils home; teaching hours are lost; attainment, attendance and wellbeing are affected.
推理链条如下：灾害事件（洪水、热浪、风暴）以更高的频率或强度发生；学校突破了某一物理或安全门槛；学校停课、延迟开放或让学生回家；教学时数损失；成绩、出勤率和身心健康受到影响。
Critically, disruption is not evenly distributed. Schools in floodplains, coastal communities, older urban buildings and deprived catchment areas absorb the greatest impacts, so climate change amplifies existing educational inequality.
关键在于，这种干扰并非均匀分布。位于洪泛平原、沿海社区、老旧城市建筑和贫困学区的学校承受着最大的冲击，因此气候变化会放大既有的教育不平等。
2. The Hazard Spectrum Facing UK Schools | 英国学校面临的气候灾害谱
UK climate projections (UKCP18) point to hotter, drier summers, milder and wetter winters, more intense short-duration rainfall, and continued sea-level rise. Each of these shifts maps onto a different school disruption mechanism.
英国气候预测（UKCP18）指向更炎热干燥的夏季、更温和湿润的冬季、更强的短时强降雨以及持续的海平面上升。每一种变化都对应着不同的学校中断机制。
- Flooding - fluvial, pluvial and coastal flooding closes buildings and cuts off travel routes. 洪水——河流洪水、地表水洪水和海岸洪水导致校舍关闭、通学路线中断。
- Extreme heat - overheating classrooms, unsafe playgrounds and transport. 极端高温——教室过热、操场和交通不安全。
- Storms and high winds - red warnings, structural damage, power loss. 风暴与大风——红色预警、结构损坏、停电。
- Coastal change - erosion and sea-level rise force relocation. 海岸变化——侵蚀与海平面上升迫使学校搬迁。
- Drought and wildfire - water supply failure, field fires, subsidence. 干旱与野火——供水中断、场地火灾、地基沉降。
Projected changes by the 2070s under a high-emissions pathway include roughly a 20-30% decline in summer rainfall and a 15-25% increase in winter rainfall, so both the wet and the dry ends of the spectrum intensify.
在高排放情景下，到 2070 年代夏季降雨量预计减少约 20-30%，冬季降雨量增加约 15-25%，因此灾害谱的"湿"端与"干"端都会加剧。
3. Flooding: The Single Biggest Cause of Closure | 洪水：停课的最大单一原因
Flooding is the dominant climate-related cause of school closure in the UK. The Environment Agency assesses that over five million properties in England sit in flood-risk zones, and sector estimates place several thousand schools wholly or partly within those zones.
洪水是英国与气候相关的最主要停课原因。英国环境署评估英格兰有超过五百万处房产位于洪水风险区，而行业估算显示有数千所学校全部或部分位于这些区域内。
Three flood types matter for schools. Fluvial flooding (rivers overflowing) caused the prolonged Somerset Levels disruption of 2013-14, when the village of Muchelney was cut off for weeks. Pluvial flooding (surface water) paralyses urban schools within minutes, as seen in London in July 2021. Coastal and tidal flooding, driven by storm surges and sea-level rise, threatens schools on low-lying estuaries.
有三类洪水对学校至关重要。河流洪水（河水漫溢）造成了 2013-14 年萨默塞特平原的长期中断，当时 Muchelney 村被隔绝数周。地表水洪水（内涝）能在几分钟内让城市学校瘫痪，如 2021 年 7 月的伦敦。由风暴增水和海平面上升驱动的海岸与潮汐洪水，则威胁着低洼河口的学校。
Crucially, a school building need not be flooded to close. Flooded access roads, a failed pumping station, contaminated water supplies or a power cut to the boiler room are enough. Recovery is often slower than the flood itself: drying out, mould remediation, electrical testing and replacement of flooring can keep pupils out for weeks or months.
关键的是，学校建筑本身不必被淹也可能停课。通学道路被淹、泵站失效、供水中断或锅炉房断电就足够了。而恢复往往比洪水本身更慢：抽湿、除霉、电气检测和更换地板可能让学生停课数周甚至数月。
4. Extreme Heat and Overheating Classrooms | 极端高温与教室过热
Heat is the fastest-growing disruption risk. On 19 July 2022 the UK recorded 40.3 °C at Coningsby, Lincolnshire, the first time 40 °C had been exceeded in the national record, and dozens of stations passed 40 °C on the same day.
高温是增长最快的干扰风险。2022 年 7 月 19 日，英国林肯郡 Coningsby 录得 40.3 °C，这是全国记录中首次突破 40 °C，同日有数十个站点超过 40 °C。
Design guidance sets a clear operational threshold. Building Bulletin 101 (BB101), the ventilation and thermal comfort standard for English schools, states that internal air temperature should not exceed 28 °C for more than 120 hours per year, and should not exceed 26 °C for more than 400 hours per year.
设计指南设定了明确的运行门槛。英格兰学校通风与热舒适标准《建筑公报 101》（BB101）规定：室内气温每年超过 28 °C 的时间不应超过 120 小时，超过 26 °C 的时间不应超过 400 小时。
T ≥ 28 °C) ≤ 120 h yr⁻¹ and Σ (hours with T ≥ 26 °C) ≤ 400 h yr⁻¹
Many UK schools were never designed for these limits. Flat roofs, extensive south-facing glazing, dark asphalt playgrounds, poor cross-ventilation and carpeted teaching blocks combine to trap heat. Because the UK summer term runs into late July, and the autumn term begins in early September, the hottest weeks now coincide directly with examinations and the start of teaching.
许多英国学校从未按这些限值设计。平屋顶、大面积朝南玻璃、深色沥青操场、通风不良以及铺地毯的教学楼共同造成热量积聚。由于英国夏季学期延续到 7 月下旬，而秋季学期在 9 月初开始，最热的几周如今正好与考试期和开学教学期重合。
Responses range from early closure and shortened days to cancellation of sports fixtures, moving examinations to halls with cooling, and in some cases full closure. Evidence from international studies also links hotter classrooms to measurable falls in test performance, meaning heat affects attainment even when schools remain open.
应对方式从提早放学、缩短课时，到取消体育比赛、把考试移至有降温设施的大厅，某些情况下甚至全面停课。国际研究的证据还表明，更热的教室与考试成绩的可测量下降相关，这意味着即使学校保持开放，高温也会影响学业表现。
5. Storms, High Winds and Named Weather Events | 风暴、大风与命名天气事件
Named storms now regularly trigger mass closures. The Met Office red warning system is the key decision trigger: when a red warning for wind is issued, local authorities and multi-academy trusts typically instruct schools to close because travel is unsafe and flying debris poses a risk to life.
命名风暴如今经常引发大规模停课。英国气象局的红色预警系统是关键决策触发点：一旦发布大风红色预警，地方政府和多个学院信托通常会指示学校停课，因为出行不安全且飞散碎片危及生命。
- Storm Eunice, February 2022 - red warnings across southern England and south Wales; hundreds of schools closed and many more opened late. 2022 年 2 月的风暴 Eunice——英格兰南部和南威尔士发布红色预警，数百所学校停课，更多学校延迟开放。
- Storm Babet, October 2023 - severe flooding in Scotland and the Midlands; schools closed in Angus and beyond. 2023 年 10 月的风暴 Babet——苏格兰和中部地区严重洪灾，安格斯等地学校停课。
- Storm Bert, November 2024 - widespread flooding in Wales and the west; hundreds of closures. 2024 年 11 月的风暴 Bert——威尔士和西部大范围洪灾，数百所学校停课。
- Storm Darragh, December 2024 - red warning for wind in Wales and south-west England; mass closures and power outages. 2024 年 12 月的风暴 Darragh——威尔士和英格兰西南部大风红色预警，大规模停课与停电。
An important geographical nuance: warmer winters are reducing the frequency of traditional snow days, but the same warming is increasing the frequency of intense cyclonic storms and heavy rainfall events. The disruption does not disappear; it changes type and becomes less predictable.
一个重要的地理学细节是：更温暖的冬季减少了传统"雪天停课"的频率，但同样的增温又增加了强气旋风暴和强降雨事件的频率。干扰并未消失，而是改变了类型并变得更难预测。
6. Coastal Change and Sea-Level Rise | 海岸变化与海平面上升
Sea-level rise is a slow-onset hazard with irreversible consequences for coastal schools. UKCP18 projections for London under a high-emissions scenario indicate a rise of roughly 0.3 m by 2050 and up to about 1 m or more by 2100, with comparable or larger values in some estuaries.
海平面上升是一种缓发灾害，对沿海学校具有不可逆的后果。UKCP18 在高排放情景下对伦敦的预测显示，到 2050 年上升约 0.3 米，到 2100 年可达约 1 米甚至更多，部分河口数值相当或更大。
Two mechanisms affect schools. First, tidal flooding and storm surges make low-lying coastal schools progressively more vulnerable, since a surge that once arrived once a century may arrive once a decade. Second, coastal erosion physically removes the land on which schools stand, particularly on soft cliffs in Norfolk, Yorkshire, Cumbria and parts of Wales.
有两种机制影响学校。第一，潮汐洪水和风暴增水使低洼沿海学校日益脆弱，因为过去百年一遇的增水可能变成十年一遇。第二，海岸侵蚀会直接吞蚀学校所在的土地，尤其是在诺福克、约克郡、坎布里亚和威尔士部分地区的软质崖岸。
The disruption here is structural and long-term rather than a single closure. Managed realignment and coastal defence decisions may result in a school being relocated, merged or closed permanently, which fragments communities and forces long pupil journeys.
这里的中断是结构性和长期性的，而非单次停课。海岸管理线调整和海岸防护决策可能导致学校搬迁、合并或永久关闭，从而割裂社区并迫使学生长途通学。
7. Drought, Water Shortage and Wildfire | 干旱、缺水与野火
Drought is often overlooked because it seems less dramatic than a flood, yet it can close a school outright. Schools are intensive water users: toilets, kitchens, cleaning, hand hygiene and, increasingly, irrigation for playing fields.
干旱常被忽视，因为它似乎不如洪水戏剧化，但它可以直接让学校停课。学校是用水大户：厕所、厨房、清洁、手部卫生，以及越来越多的运动场灌溉。
A school cannot legally operate without functioning toilets and safe water, and it cannot provide free school meals without a working kitchen. When reservoirs fall and pressure drops, or when a private borehole runs dry, closure or part-time operation follows. England declared drought status in August 2022, and dry winters in 2023 and 2025 renewed pressure on supplies.
学校在没有可用厕所和安全用水的情况下无法合法运行，没有可运作的厨房也无法提供免费校餐。当水库水位下降、水压不足，或私人水井干涸时，随之而来的就是停课或部分时段运行。英格兰于 2022 年 8 月宣布进入干旱状态，2023 年和 2025 年的干燥冬季再次加剧了供水压力。
Heat and drought also raise wildfire risk on school grounds and surrounding heathland. The July 2022 fires in Wennington, east London, destroyed homes and forced local school closures, and grass fires near school playing fields have become a recurring summer incident for fire and rescue services.
高温与干旱还提高了校园及周边荒地的野火风险。2022 年 7 月伦敦东部 Wennington 的火灾摧毁了住宅并迫使当地学校停课，而校园运动场附近的草地火灾已成为消防部门每年夏季反复处置的事件。
8. Indirect Effects: Staff, Transport, Health and Wellbeing | 间接影响：教职工、交通、健康与福祉
Direct closures are only part of the story. Much of the attendance loss caused by climate change is indirect and harder to count, which makes it an excellent evaluative point in extended answers.
直接停课只是故事的一部分。气候变化造成的出勤损失很大一部分是间接的、更难统计的，这使它成为论述题中极佳的评析点。
- Staff absence - flooded homes, impassable routes and heat stress reduce the number of adults able to work, and schools may close because they cannot be safely supervised. 教职工缺勤——住宅被淹、道路不通和热应激减少了可到岗的成年人，学校可能因无法安全监管学生而停课。
- Transport failure - flooded roads, cancelled buses, rail speed restrictions when rails buckle above roughly 30 °C. 交通失效——道路被淹、公交取消，铁轨在约 30 °C 以上膨胀变形导致限速。
- Health impacts - heat exhaustion, asthma triggered by longer pollen seasons and wildfire smoke, and anxiety or trauma among pupils after flooding. 健康影响——中暑、花粉季延长与野火烟雾诱发的哮喘，以及洪水后学生的焦虑或创伤。
- Compounding absence - pupils who miss weeks after a flood often become persistently absent afterwards, and disadvantaged pupils lose the most ground. 缺勤叠加——洪水后缺课数周的学生往往此后长期缺勤，弱势学生落后最多。
There is also a wider economic dimension: unplanned closures force working parents to take leave or pay for emergency childcare, so the cost of climate disruption extends well beyond the school gate.
还有一个更广泛的经济维度：计划外停课迫使在职父母请假或支付紧急托育费用，因此气候干扰的成本远远超出校门之外。
9. Measuring the Impact: Quantifying Disruption | 影响的量化：衡量干扰
A-Level geography rewards quantification. Attendance, lost teaching hours and risk can all be expressed mathematically, and using these expressions strengthens analysis.
A-Level 地理学重视量化。出勤率、损失的教学时
