Is the 'Doomsday Glacier' Already Doomed? Scientists Say We Might Be at the Tipping Point

‘末日冰川’已经注定毁灭了吗?科学家警告:我们可能正站在临界点上

Is the 'Doomsday Glacier' Already Doomed? Scientists Say We Might Be at the Tipping Point

科学家们正乘着名为‘阿拉昂号’的破冰船驶向思韦茨冰川——也就是所谓的‘末日冰川’——去研究它是否即将进入失控崩塌循环。听起来像科幻惊悚片,但这是现实。而且说真的,起这种名字真没什么帮助。

真正可怕的是:冰川下方的基岩向内陆倾斜,一旦‘接地线’退缩过某个临界点,温暖海水就会像暴雨时灌入地下室一样涌入。这是一个自我强化的循环——融化导致退缩,退缩引发更多融化。而我们远未达到能阻止它的减排水平。

Fun fact: the ‘Doomsday Glacier’ nickname makes my job 50% harder. Journalists love it, but it makes people think collapse is inevitable. It’s not. What we’re seeing is a possible irreversible retreat — IF warming continues. But IF we slash emissions, we might stabilize it. The science says it’s still possible. So please, stop saying it’s doomed.

冷知识:‘末日冰川’这个外号让我工作难度直接翻倍。记者爱用,但大众一听就以为崩塌不可避免。其实并非如此。我们观察到的是一种‘可能的’不可逆退缩——前提是持续变暖。如果我们大幅减排,仍有可能让它稳定下来。科学告诉我们这还办得到。求求了,别再说它注定毁灭了。

Policy Wonk from Miami (迈阿密政策书呆子)
Look, I get the science, but my city is already installing pumps for high-tide flooding. We don’t have the luxury of ‘maybe it’s reversible.’ We’re planning for 2-foot sea rise by 2050. Call it doom or not—our basements are already wet.

听着,我懂科学,但我们城市已经在为涨潮洪水安装抽水泵了。我们没资本去讨论‘也许还能逆转’。我们正按2050年海平面上升2英尺来规划。你爱叫它末日不末日——反正我们地下室已经进水了。

Skeptical Engineer (怀疑派工程师)
The ‘basement flood’ analogy is dramatic, but is it accurate? Warm water does melt ice, but ocean currents are complex. We’re modeling this on 2023 data—what if a new current pattern emerges? Let’s not turn projections into prophecies.

‘地下室进水’的比喻很戏剧化,但准确吗?暖流确实会融化冰,但洋流极其复杂。我们用的是2023年的数据建模——万一出现新的洋流模式呢?别把预测当成预言。

Climate Realist (气候现实主义者)
We need both: the dramatic awareness and the scientific caution. The nickname sucks, but it got you here, didn’t it? Now that you’re here—let’s talk solutions. Carbon capture? Geoengineering? Or just finally taxing fossil fuels like we should have in 2005?

我们两者都需要:戏剧性的警醒,以及科学的谨慎。这名字是烂,但它把你吸引来了,对吧?既然来了——咱们聊聊解决方案。碳捕捉?地球工程?还是干脆像2005年就该做的那样,给化石燃料征税?

Oceanography PhD Candidate (海洋学博士生)
The part about ice cliffs collapsing? That scenario’s looking less likely now, per 2024 modeling. But that doesn’t mean we’re safe—just that one nightmare path is off the table. The warm-water-under-ice path? That’s still very much on fire.

关于冰崖崩塌的部分?根据2024年的模型,这种情景现在看来可能性变小了。但这不代表我们安全了——只是少了一个噩梦路径。暖水侵蚀冰层的路径?那条路现在依然火光冲天。

Eco-Anxious Student (焦虑的环保学生)
Every time I read about Thwaites, I can’t sleep. It’s not just ‘sea level rise’—it’s entire cultures, ecosystems, cities. And the leaders are still arguing about quarterly profits. Sometimes I wonder if ‘doomed’ isn’t the right word after all.

每次读到思韦茨冰川的新闻,我都睡不着。这不只是‘海平面上升’——而是整个文明、生态系统、城市的命运。可领导人还在争论季度利润。有时我在想,‘注定毁灭’这个词也许根本没错。

Cynical Futurist (愤世嫉俗的未来学家)
Here’s my hot take: we won’t act until Miami is half-submerged. By then, ‘Doomsday Glacier’ won’t be a nickname. It’ll be a memorial.

我说句逆耳忠言:除非迈阿密一半被淹,否则我们根本不会行动。到那时,‘末日冰川’就不再是个绰号了——而会成为一座墓碑。
