圣迭戈县宣布10月1日至8日为气候周，聚焦蒂华纳河污染治理
圣迭戈县消息——圣迭戈县政委员会宣布将2026年10月1日至8日定为「圣迭戈气候周」。据CitizenPortal对县政会议的记录，县政委员在宣布仪式上表示，为期一周的活动将通过社区讲座、清洁行动与政策讨论，推动居民与地方政府共同应对气候变化带来的高温、干旱与海岸侵蚀等挑战。
今年气候周的重点议题之一是蒂华纳河（Tijuana River）跨境污染问题：来自墨西哥一侧的污水与垃圾长期流入圣迭戈县南部海滩，造成海滩频繁关闭。县方同时关注联邦近海石油钻探动向对本县海岸的影响，并提醒公众，《清洁水法》相关公众意见征集将于10月9日截止，居民可在期限前提交意见。
圣迭戈地区是加州最早系统推动气候行动规划的县之一。县政府表示，气候周的各项活动向公众开放，具体场次可通过县政府网站查询，沿海城市与社区组织也将同期举办配套活动。
蒂华纳河污染是圣迭戈县持续数十年的环境难题：河水裹挟的污水在雨季与设备故障时跨境北流，帝国海滩（Imperial Beach）等南部海滩一度长年频繁关闭，冲浪者与沿岸居民的健康投诉不断。县政府近年来与州政府、联邦机构及墨西哥方面就污水处理设施的扩建与维护持续交涉，并把这一议题带进气候周，正是希望公众在讨论气候的同时，也关注已经影响日常生活的跨境污染。气候周的其他活动还包括社区植树、海岸清洁与学校环保课程，县环境部门表示，活动安排刻意分散到全县各社区，方便不同地区的居民就近参与。错过现场活动的居民，也可在县政府网站回看部分讲座的录像与资料。

San Diego County Proclaims October 1–8 Climate Week, With Tijuana River Pollution in Focus
SAN DIEGO COUNTY — The San Diego County Board of Supervisors has proclaimed October 1–8, 2026 as San Diego Climate Week. According to CitizenPortal's record of the board proceedings, supervisors said the week of events — community talks, cleanups and policy discussions — is meant to engage residents and local governments on challenges from extreme heat and drought to coastal erosion.
A central focus this year is cross-border pollution in the Tijuana River: sewage and trash flowing from the Mexican side have long fouled beaches in the county's south, forcing frequent closures. The county is also tracking federal offshore drilling proposals affecting its coastline, and reminded the public that comments under the Clean Water Act process are due by October 9.
San Diego was among the first California counties to adopt a systematic climate action plan. The county said Climate Week events are open to the public, with schedules on the county website, and coastal cities and community groups are holding related activities during the week.
Tijuana River pollution has plagued San Diego County for decades: sewage-laden flows cross the border during storms and equipment failures, and southern beaches such as Imperial Beach have faced frequent, sometimes prolonged closures, with surfers and coastal residents reporting illnesses. The county has pressed state and federal agencies — and, through them, Mexican counterparts — on expanding and maintaining treatment facilities for years, and it folded the issue into Climate Week to connect climate discussion with a pollution problem that already shapes daily life. Other Climate Week programming includes community tree plantings, coastal cleanups and school environmental lessons, deliberately spread across the county so residents can join nearby; recordings and materials from several talks will be posted on the county website for those who miss the live events.
