Study warns of longer extreme heat periods by century's end_我的网站

A |          (ECNS) -- Hot days worldwide could experience around four additional hours of extreme heat by the end of the 21st century under a high-emissions scenario, according to a study led by Chinese researchers.    Published in Nature Climate Change, the study found that traditional daily temperature indicators may overlook shorter periods of extreme heat, while hourly temperature analysis can provide a more detailed picture of heat exposure and associated risks.        Researchers from Sun Yat-sen University and other institutions analyzed global hourly temperature data from 1981 to 2023, combining observational records with climate model projections to assess how extreme heat exposure could change in the future.    The research team found that the duration of extreme heat increased by 62 hours per decade over the study period. Around 28% of extreme heat events occurred on days that would not have been classified as hot days based on conventional daily temperature indicators.    Under a high-emissions scenario known as SSP5-8.5, the researchers projected that between 2070 and 2099, each hot day could experience around four additional hours of extreme heat compared with the 2001-2023 period. Days not classified as hot could also see increased periods of extreme heat.    The study also found that low- and middle-income countries account for a disproportionately large share of both current and projected extreme heat exposure. Younger generations in low-income countries are expected to experience the greatest increase in lifetime exposure.    Researchers said the findings could help improve heat-warning systems, strengthen assessments of health risks and support climate adaptation efforts.    (By Helen Mo, intern Liu Shuangjing)                    。    

　    阿里云优惠券 先领券再下单        上周，我终于把 AI 编程助手从“玩具”变成了“生产力工具”。    不是靠换模型，也不是买新电脑，而是用了阿里云刚推的 百炼 Coding Plan。    

    以前用，免费额度跑两下就没了；调个 API，动不动超限。    现在？每月 90000 次请求，固定月费，不限速，还能在主流工具里直接用。    一、它到底解决了什么痛点？    很多开发者都经历过：    免费 API 调几次就 429，打断编码节奏   自建推理成本高，小项目扛不住   不同工具要配不同 Key，管理混乱    Coding Plan 把这些全包了：    固定月费（首月 7.9 元，之后续费 5 折起）   每月 90000 次请求额度，覆盖日常开发需求   一套 Key 通吃多个工具：Qwen Code、Claude Code、Cline、OpenClaw 都支持。    相当于办了张“AI 编程月卡”，不用再算 token、看配额、怕超支。    二、怎么用？三步搞定    买套餐    首购 7.9 元/月（新用户专享），在阿里云活动页下单即可。    官网链接：https://www.aliyun.com/activity/ecs/clawdbot?userCode=i4hlo7k3    拿 Key    进百炼控制台 → Coding Plan → 获取专属 API Key。

B |     这个 Key 用于 Coding Plan 套餐，和通用 API 分开，账单清晰。    接入工具    在 Qwen Code 里运行 /auth，选 “api-key”，填入 Key   在 VS Code 插件设置里粘贴 Key   Cline 或 OpenClaw 也类似，填一次就行    全程不用改代码，不配代理，开箱即用。

C |     三、支持哪些模型？够不够强？    别以为便宜就缩水。    Coding Plan 支持当前最强的一批编码模型：    Qwen3-Coder-Plus / Next   Qwen3.5-Plus / Max   GLM-5、Kimi-k2.5、GLM-4.7    我实测用 Qwen3-Coder-Next 写 Python 爬虫，生成完整带异常处理 + 日志模块的脚本，一次通过。    调用速度比免费接口快 30%，因为走的是专用通道。    四、适合谁用？    个人开发者：写 side project、自动化脚本，不再被额度限制   学生：做课程设计、竞赛项目，低成本用上顶级模型   小团队：统一 API Key 管理，避免每人乱申请额度    如果你每天写代码超过 1 小时，    这个计划大概率能省下你的时间和焦虑。

D |     五、一点提醒    首月 7.9 元仅限新用户，老用户可享续费 5 折   请求次数按“有效调用”计费，失败不扣   超出 90000 次后自动降级到按量付费，不会中断服务。    最后    AI 编程不该是“省着用”的奢侈品。         百炼 Coding Plan 把门槛打下来了——
一杯奶茶的钱，换来一个月无感调用顶级编码模型的自由。    别再让额度焦虑打断你的 coding flow。

花 5 分钟配置好，
接下来的日子，只管写代码，剩下的交给 AI。    官网链接：https://www.aliyun.com/activity/ecs/clawdbot?userCode=i4hlo7k3
