A pioneering geoengineering experiment conducted on Arctic sea ice near Cambridge Bay in northern Canada has yielded its first promising results.

一项在加拿大北部靠近剑桥湾的北极海冰上进行的前瞻性地球工程实验，已经取得了其首批令人期待的成果。

The project, operated by a British company called Real Ice and funded by the United Kingdom government, aims to combat accelerating ice loss by artificially thickening the polar ice sheet.

该项目由一家名为 Real Ice 的英国公司运营，并由英国政府资助，旨在通过人工增厚极地冰盖来应对加速流失的冰层。

Andrea Ceccolini, the project leader, emphasized that such outcomes would have seemed inconceivable merely a year ago.

项目负责人安德里亚·塞科利尼强调，这样的成果在仅仅一年前似乎还是不可思议的。

Five months prior to the observation, researchers had endured temperatures plunging to minus forty degrees Celsius while drilling holes into the sea ice.

在进行观察的五个月前，研究人员在海冰上钻孔时，忍受了骤降至摄氏零下四十度的低温。

They subsequently pumped approximately fifty thousand tonnes of ocean water onto the frozen surface, where it solidified almost instantaneously.

他们随后将大约五万吨的海水抽到冰冻的表面上，海水在那里几乎瞬间凝固了。

According to recent measurements, this technique succeeded in augmenting the existing ice depth of one and a half metres by roughly fifty centimetres.

根据最近的测量结果，这项技术成功地将现有1.5米的冰层厚度增加了大约50厘米。

The thickened ice has demonstrably resisted early seasonal melting more effectively than untreated areas nearby.

经增厚的冰层已显著比附近未经处理的区域更有效地抵抗了早期的季节性融化。

The visual contrast between treated and untreated ice was striking during the team's recent inspection.

在团队最近的考察中，经处理与未经处理的冰面之间的视觉对比非常显著。

Whereas the artificially thickened sections remained a brilliant white with a light dusting of reflective snow, adjacent areas had already deteriorated into sky blue meltwater ponds.

然而，人工加厚的部分仍保持着带有轻微反射雪花的亮白色，而邻近区域却早已退化成天蓝色的融冰池。

Ceccolini noted that one could literally point to the boundary separating the two dramatically different surfaces.

塞科利尼指出，人们真的可以用手指着区分这两个截然不同表面的边界。

Were this approach to prove scalable, it could represent a significant breakthrough in environmental solutions for the climate crisis.

倘若这种方法被证明可行，它可能代表着应对气候危机之环境解决方案的重大突破。

However, the broader environmental context remains deeply concerning for scientific research teams working in the region.

然而，对于在该地区工作的科学研究团队来说，更广泛的环境背景仍然令人深感担忧。

Temperatures in Cambridge Bay, known as Ikaluktutiak in the Inuit language, have exceeded five degrees Celsius, far surpassing the typical range of minus six to one degree.

在因纽特语中被称为伊卡卢克图蒂亚克的剑桥湾，其气温已超过摄氏五度，远远超过了零下六度至一度的典型范围。

Ceccolini cautioned that conditions were severely out of balance, a phenomenon not confined to this single location but indicative of wider Arctic climate change.

塞科里尼警告说，情况严重失衡，这种现象不仅限于这单一地点，还预示着更广泛的北极气候变化。

#15

Not only is sea ice vanishing at an unprecedented rate, but its disappearance is also amplifying global warming through reduced reflectivity of solar radiation.

海冰不仅正以空前的速度消逝，其消失还通过太阳辐射反射率的降低，进而加剧全球暖化。
