earth.nullschool.net 是一个长期存在、被广泛引用的开源数据可视化项目，其核心价值在于将全球气象与海洋数据（如风向、洋流、温度、污染颗粒物等）以动态粒子动画的形式叠加在地球模型上，用户可旋转、缩放并切换不同数据图层。它常被用于教学、新闻报道和气象科普场景，因其直观呈现大尺度自然现象而受到技术社区关注。
此次在 Hacker News 上被再次分享并获得少量互动，反映出该工具在数据可视化领域的持续影响力，也说明此类"数据即艺术"的开源项目在开发者群体中仍有稳定的受众。相比同日其他帖子（如代码工具、视频编码对比等），本条热度较低，但作为经典项目的周期性曝光，其意义更多在于唤起新用户对公开环境数据可视化资源的关注，而非带来新的技术进展或争议。

Weather and climate data shown on this website and countless others are at risk.
The National Oceanic and Atmospheric Administration (NOAA) is the U.S. agency responsible for global weather forecasting, hurricane prediction, ocean observation, and many other services vital to public safety. Its satellites, supercomputers, and research teams provide essential data that help us understand our planet and protect lives.
On February 27, the new U.S. administration initiated mass firings at NOAA. These actions are unethical and deeply disruptive to the talented scientists and engineers who dedicate themselves to the public good. The firings, along with expected budget cuts, have serious implications for the availability and quality of weather forecasts produced by the United States. They must be reversed immediately.
Much of the data on this website is downloaded directly from NOAA's servers. In this environment of uncertainty, access could be disrupted at any time. While I'll strive to keep all features on this website functional and switch to alternative data sources if necessary, some datasets have no substitute if they go offline.
If this concerns you, speak up. Share on social media. And if you're in the U.S., contact your representatives.
