节气专家说之小寒******
每到公历1月5日前后的时候，我们就会迎来小寒节气。小寒，说明这个时候非常寒冷，但实际上小寒和紧接其后的大寒，都是一年当中最寒冷的时节。
在这样的一个时间段里，河水结的冰已经非常厚了。早在《周礼》当中就有记载在这个时候藏冰的做法，专门有人来负责和冰有关的事宜，叫“凌人”。那这个就是关于古人怎么样利用自然之物，来顺利地度过一年四季，春夏秋冬。夏天非常炎热，不像我们现在有冰箱有空调，可以调节温度。那古人没有，但他们想出了办法，就是在冬天的时候为夏天做好准备。所以在小寒时节就有藏冰的做法，《诗经》里面就有讲说，“二之日凿冰冲冲，三之日纳于凌阴”，就是把冰取下来之后放到专门的场所。在清朝，仍然保留着凿冰的做法，我们前面讲到过，每到立夏日、伏日的时候，皇帝都会颁赐给大臣一些冰。
除了藏冰以外，古人也发明了很多的冰上的游戏和竞技，这就是冰嬉。在北京，明代就有记载，大家会有冰上的嬉戏活动，尤其是在什刹海、中南海一带。现在的故宫博物院当中，还藏有冰嬉图。我们从冰嬉图上是可以看到当年清朝宫廷当中非常盛大的冰上运动，场面非常壮观。
还有一个“二十四番花信风”的习俗，也是从小寒节气开始算起的。节气三候，从小寒到谷雨，总共是八个节气，总共是二十四候。在小寒这个节气里有三种花应时开放，一种是梅花，一种是山茶花，一种是水仙花。梅花大家都道其性情高洁，和梅兰竹菊构成“四君子”，又和竹松构成“岁寒三友”，在中华传统文化当中有非常高的地位；山茶花也是一种非常美好的象征；水仙花在北京被称为“年花”，小寒的时候，人们买来水仙花，晒水仙，经过一段时间的培育，到了春节的时候正好开放。水仙花和春节的喜庆、团圆，春天将至的特点结合起来，特别能够为春节增加色彩。

中新网评：处理核污水绝不是日本自家私事******
中新网北京1月19日电(蒋鲤)日本政府近日称，将于2023年春夏期间开始向海洋排放经过处理的福岛第一核电站核污水。日本罔顾国内民众及周边国家的屡屡反对，企图将核污水“一倒了之”，把一件关乎全球海洋生态环境和公众健康的事当成了自家私事。
资料图：日本福岛第一核电站。2011年，福岛核电站事故发生后，大量放射性物质泄漏到大气层和太平洋，对周围环境造成了难以逆转的伤害，数十万人被迫撤离该地区。时至今日，作为日本邻国之一的韩国仍未解除福岛海鲜禁令。
日本以核污水存储能力即将达到上限为由，在2021年4月13日，正式决定将福岛第一核电站核污水排入太平洋。过去一年多，日本政府和东京电力公司一直在持续推进核污水排海计划。
日本政府辩称，这些核污水经多核素处理系统(ALPS)处理后很安全，甚至“可以喝”，这样的表态无疑在愚弄大众。
事实上，经过处理的核污水仍含有多种放射性物质，核污水一旦排放入海就无法回收，长期来看，将会给海洋生态带来难以估量的潜在威胁，最终危害人类健康。
因此，核污水排海计划推出后，遭到日本民众强烈反对。日本《朝日新闻》2022年3月公布的问卷调查显示，福岛县、宫城县和岩手县受访的42个市町村长中，约六成反对东京电力公司福岛第一核电站核污水排放入海。日本全国渔业协会联合会也多次申明立场，反对该计划。
日本政府认为，核污水排海是最便宜、最省事的解决方案，但此举却将周边国家乃至全世界置于核污染风险中。太平洋非日本一家之海，核污水会随着洋流流动，其影响势必会跨越国界，危害周边国家乃至整个国际社会的公共福祉和利益。
《韩国经济新闻》发文称，相关研究认为，福岛核污水如果排放入海，约7个月后将到达济州等韩国海域，该国水产业和旅游业将遭受相当大的损失。
德国南极海洋机构也曾发出警告，若日本将所有核污水排入海中，不到半年，整个太平洋都将面临高度辐射威胁，包括远在大洋另一端的美国。太平洋地区人民更是对日本该计划持反对意见。
日本作为《联合国海洋法公约》缔约国，有义务保护海洋环境。然而，在核污水排海方案的正当性、核污水数据的可靠性、净化装置的有效性、环境影响的不确定性等问题上，日本未能作出科学、可信的说明。
国际原子能机构技术工作组虽已三次赴日实地考察评估，但尚未就日排海方案的安全性给出结论，并且对日本提出诸多澄清要求和整改意见。在此情况下，日本仍执意推进核污水排海工程建设，这是极不负责任的行为。
太平洋不是日本的下水道，日本必须正视各方合理关切，在与周边国家等相关利益方和国际原子能机构充分协商后，制定合理的核污水处理方案。日本也要着眼长远，若只顾眼前，执意将核污水排放入海，不仅其自身，周边国家乃至全世界都将为之买单，其后果必将会危害数代人。
Fukushima water disposal by no means Japan’s own business
By John Lee
(ECNS) -- Japan has announced it will release treated wastewater from the wrecked Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean this year.
Although Fukushima wastewater disposal affects global marine ecological environment protection and public health, Japan has turned a deaf ear to domestic and international opposition to dumping the contaminated water into the sea, treating the "global" matter as its own business.
The Fukushima accident in 2011 had sent large quantities of radiation into the atmosphere and the Pacific Ocean, causing irreversible damage to the surrounding environment, and hundreds of thousands of people were forced to evacuate the area. South Korea still maintains its import ban on Japanese seafood from areas affected by the Fukushima nuclear disaster.
On April 13, 2021, Japan announced it had decided to discharge contaminated radioactive wastewater in Fukushima Prefecture into the sea due to dwindling storage space, with the Japanese government and plant operator Tokyo Electric Power Company Holdings Inc. promoting the release plan over the past year.
The Japanese government argues that the water treated by an advanced liquid processing system, or ALPS, is safe and drinkable, which is undoubtedly fooling the public.
In fact, the treated wastewater still includes a variety of radioactive substances and can’t be recycled once discharged into the sea, which will pose a great threat to marine ecology and ultimately endanger human health in the long run.
Therefore, the discharge plan has been strongly opposed in Japan. According to a questionnaire conducted by The Asahi Shimbun, nearly 60 percent of mayors of 42 municipalities in Iwate, Miyagi and Fukushima prefectures oppose the discharge plan. The National Fisheries Cooperative Federation of Japan has also repeatedly stated its opposition in public.
The Japanese government believes that dumping Fukushima wastewater into the sea is the cheapest and most convenient solution, but neighboring countries and even the whole world will be at risk of nuclear pollution.
The Pacific Ocean doesn’t belong to Japan and the wastewater flow along oceanic currents will surely break boundaries and endanger public welfare and the interests of neighboring countries and even the international community.
The Korea Economic Daily reported that related research concluded that if contaminated water from Fukushima is released into the ocean, it would only take seven months for the contaminated water to reach the shores of Jeju Island, with the country's aquaculture and tourism suffering considerable losses.
According to the calculation of a German marine scientific research institute, radioactive materials will spread to most of the Pacific Ocean within half a year from the date of discharge, and the U.S. and Canada will be affected by nuclear pollution. People in the Pacific region also oppose the discharge plan.
As a participant of the United Nations Convention on the Law of the Sea, Japan has the obligation of protecting the marine environment.
However, it hasn’t offered a full and convincing explanation on issues like the legitimacy of the discharge plan, the reliability of data on the nuclear-contaminated water, the efficacy of the treatment system or the uncertainty of environmental impact.
Though the IAEA has yet to complete a comprehensive review after three investigations in Japan, the Japanese side has been pushing through the approval process for its discharge plan and even started building facilities for the discharge. It is rather irresponsible for Japan to act against public opinion at home and concerns abroad.
The Pacific Ocean is not a private Japanese sewer. The country must seriously heed the voices of the international community and make a reasonable plan for the Fukushima wastewater disposal after full consultation with stakeholders and international agencies.
If it only seeks instant interest and insists on discharging the contaminated water into the sea, not only itself, but also its neighboring countries and the entire world will pay for the decision and several generations will be forced to bear the consequence.
