Scientists now have unambiguous proof that a phenomenon critical to predicting the impact of climate change exists.
Researchers announced Thursday that they had detected the sea level “fingerprint” of the Greenland ice sheet melt, pinpointing the unique pattern of sea level change lixed to the melting ice.
It’s the first time such a fingerprint has been definitively measured. While scientists agreed such fingerprints theoretically exist, the dynamic nature of the ocean had made it difficult to identify them confidently — until now.

科学家们现在有了明确的证据,证明了存在一种对预测气候变化影响至关重要的现象
研究人员周四宣布,他们已经检测到了格陵兰冰盖融化的海平面 "指纹",准确地指出了与冰层融化有关的海平面变化的独特模式。
这是首次对这种指纹进行明确测量。虽然科学家们曾认为这种指纹在理论上是存在的,但是海洋的动态性质使得我们很难有把握地识别它们,不过现在可以了。

The findings, which were possible with the help of high-resolution satellite observations, detail the unique pattern of sea level change lixed to the Greenland ice sheet. The fingerprints are factored into models to predict overall sea level rise.
The discovery confirms and adds confidence to the sea level changes forecast by computational models. They are critical for understanding the consequences of climate change and preparing for future hazards. It is now more than clear that the melting of the Greenland ice sheet is accelerating, said Sophie Coulson a postdoctoral fellow at Los Alamos National Laboratory. Coulson is the lead author of the study that led to the findings, which were published in the journal Science.

借助于高分辨率卫星观测,这些发现详细描述了与格陵兰冰原相关的海平面变化的独特模式。这些指纹被纳入预测整体海平面上升的模型之中。
这一发现证实并增加了计算模型对海平面变化预报的可信度。它们对于理解气候变化的后果和为未来的灾害做好准备至关重要。洛斯阿拉莫斯国家实验室的博士后苏菲·库尔森表示,现在非常清楚的是,格陵兰冰原正在加速融化。库尔森是这项研究的主要作者,该研究导致了这一发现,并发表在《科学》杂志上。

Until recently, fingerprint science was restrained by a lack of satellite observations — records documented only the southern tip of Greenland, making it difficult to examine the oceans around it.
The Greenland ice sheet, which covers almost 80% of the island country, contains enormous quantities of frozen water. The rapid melting of the Greenland ice sheet is responsible for 20% of the current sea level rise globally, and a recent study predicted its disintegration would raise global sea levels by at least 10 inches, even if people stop burning fossil fuels.

直到最近,指纹科学还因缺乏卫星观测而受到限制,只有格陵兰岛南端的记录,这使得研究其周围的海洋变得困难。
格陵兰冰原覆盖了这座岛国近80%的面积,其中含有大量的冰冻水。目前全球海平面上升的20%是由于格陵兰冰原的快速融化造成的,最近的一项研究预测,即使人们停止燃烧化石燃料,它的解体也会使全球海平面上升至少10英寸。

The study was possible thanks to new satellite data shared by the Copernicus Marine Service, data that spanned over 30 years and extended to higher latitudes. Coulson plugged observations of ice-thickness change into a computational model and created a prediction of sea level from 1993 to 2019. She then compared the forecast against the new satellite data — and found a perfect match.

这项研究之所以成为可能,是因为哥白尼海洋局分享了新的卫星数据,这些数据跨越了30多年,并延伸到了更高的纬度。库尔森将冰层厚度变化的观测结果输入一个计算模型,并对1993年至2019年的海平面进行了预测。然后,她将预报与新的卫星数据进行了比较,发现完美匹配。

“It was really an exciting moment for us when we first looked at that side-by-side comparison of those observations to the model predictions,” Coulson said. “The images were staggeringly similar.”

库尔森说:“当我们第一次看到这些观测数据与模型预测数据并排比较时,这真是一个令人兴奋的时刻。这些图像惊人地相似。”

It was especially surprising because it’s unusual in geophysics to prove something is happening with a certainty of more than 99.9%, Coulson said. But it was clear that the pattern of sea level change revealed by the satellites was the fingerprint of the melting ice sheet — and that the estimation of sea level change predicted by both earlier models and Coulson’s new one was accurate.

库尔森说,这尤其让人惊讶,因为在地球物理学中,以超过99.9%的确定性来证明某些事情正在发生是不寻常的。但是很明显,卫星揭示的海平面变化模式是正在融化的冰盖的指纹,而且早期模型和库尔森的新模型预测的海平面变化的估计都是准确的。

“We can really say with great certainty that sea level fingerprints exist,” Coulson said. “The theory was correct.”

库尔森表示“我们可以非常肯定地说,海平面指纹是存在的,这个理论是正确的。”

Knowing fingerprints can be a tool to accurately predict sea level change is critical because the future of Earth’s oceans is so uncertain.

了解指纹可以成为准确预测海平面变化的工具,这一点至关重要,因为地球海洋的未来十分不确定。

“We know global sea levels will rise and that the amount and pace of sea level rise will depend on our greenhouse gas emissions,” Yarrow Axford, an associate professor at Northwestern University who studies the impact of climate change on Greenland’s glaciers and ice sheet, said by email. She was not a part of Coulson’s study.

“我们知道全球海平面将上升,海平面上升的幅度和速度将取决于我们的温室气体排放,”研究气候变化对格陵兰岛冰川和冰盖影响的美国西北大学副教授亚罗·阿克斯福德在电子邮件中表示。她没有参与库尔森研究的对象。

“But how fast the ice sheets in Greenland and Antarctica will respond to warming is a really big unknown, and frankly a very scary unknown,” Axford said.

“但是格陵兰岛和南极洲的冰原对气候变暖的反应速度究竟有多快,仍然是个未知数,坦率地说,这是一个非常可怕的未知数”阿克斯福德说。

Fingerprints are already used to inform ocean level projections and coastal planning. In the U.S., an estimated 30% of the population lives in coastline communities. Every inch of sea level rise is expected to make coastal storms more catastrophic for those populations.

指纹已经被用于海平面预测和海岸规划。在美国,估计有30%的人口生活在沿海社区。预计海平面每上升一英寸,都会使沿海风暴对这些人口造成更大的灾难。

That is partly because sea level changes can lead to more destructive storm surges, one of the deadliest aspects of hurricanes. Hurricane Ian’s storm surge, along with its winds and flooding rain, has caused devastation across Cuba and Florida. Sea level rise, along with other aspects of climate change, is expected to increase the intensity and frequency of hurricanes.

这在一定程度上是因为海平面的变化可能导致更具破坏性的风暴潮,这是飓风最致命的方面之一。飓风伊恩的风暴潮,以及它带来的风和洪水雨,已经在古巴和佛罗里达造成了破坏。海平面上升,以及气候变化的其他方面,预计将增加飓风的强度和频率。

“We’re already being forced to adapt to sea level rise around the world, and we need to do a lot more still to prepare,” Axford said. “Having decent projections of how fast our coastlines will retreat is essential for making tough decisions and the right big investments now in preparation for future sea level rise.”

“我们已经被迫适应世界各地的海平面上升,我们需要做更多的准备,”埃克斯福德说。“对于我们的海岸线将以多快的速度撤退,有一个合理的预测,对于做出艰难决定和现在进行正确的大规模投资,为未来海平面上升做好准备,是至关重要的。”

Honestly nothing will be done to stop climate change. Energy needs will keep increasing as more countries industrialize. It's time to shift to a strategy of adaptation and mitigation. Instead of lamenting and waiting for whatever catastrophes that may come in 20, 30, or 100 years, maybe it's better to prepare now. Whether people believe it's man-made or not is irrelevant. - UP: 43 DN: 9

说实话,没有什么能阻止气候变化。随着越来越多的国家工业化,能源需求将继续增加。是时候转向适应和减缓的战略了。与其为20年、30年或100年后可能发生的灾难感到悲伤和等待,不如现在就做好准备。无论人们是否相信这是人为的,都无关紧要。

The melting and freezing of ice has no manmade cause, it is all a perfectly natural process that has been going on for billions of years even when there were no homo sapiens in existence. It's perfectly ok for glaciers to melt, it's natural and normal and fully expected. The Earth is now in a period of inter-glaciation and ice melt is fully consistent with our current status. Manmade climate change is a complete political hoax, intellectually honest minds do not buy into the hoax. - UP: 29 DN: 28

"intellectually honest minds" consider the scientific advances that have been made over the last 50 years. Contrary to Marvin's claim, based on past climate cycles we have been in an "interglacial" period for over 10,000 years now and should be shifting back to a colder climate. But we are not. Human industrialization cannot be ignored as a driver to climate. It may SEEM like a small input to the overall atmosphere, but it can have an impact. We are seeing the results today of even the crude predictions of the 1980's. - UP: 4 DN: 3

“头脑清醒的人”会思考过去50年来所取得的科学进步。与你的说法相反,根据过去的气候周期,我们现在已经处于一万多年的“间冰期”,本应该会回到更冷的气候。但我们没有。人类工业化作为气候变化的驱动因素不能被忽视。虽然它可能看起来像是对整个大气层的一个小小的输入,但它可以产生影响。我们今天看到的结果,甚至是上世纪80年代的粗略预测。

Melting of glaciers began about 18,000 years ago and has raised sea level about 500 feet or 1/3 inch per year on average. On the N. America Atlantic seashore that has caused the shoreline to move westward about 60 miles or 18 feet per year on average. That should be enough evidence to make you discard the disproven hypothesis that "CO2 causes warming."

冰川的融化始于大约18000年前,使海平面上升了约500英尺或平均每年1/3英寸。在北美大西洋海岸,这导致海岸线向西移动60英里或平均每年18英尺。这应该足以让你抛弃“二氧化碳导致气候变暖”这一被推翻的假说。

You are a moor on if you think that man cannot influence the world’s climate. For example it is a documented fact that manmade fluorocarbons were creating a huge hole in the ozone layer. The world’s countries got together in what was called the Montreal Protocol and agreed to phase out the most damaging fluorocarbons of R-12 and R-22. As a result the hole in the ozone is now greatly reduced.
Scientific measurements have shown current CO2 levels are higher than they’ve been in the last 800,000 years and started increasing exponentially at the beginning of the industrial revolution with the burning of fossil fuels. The primary byproduct of burning fossil fuels is CO2 and CO2 is a greenhouse gas that causes the earth to hold heat. - UP: 5 DN: 1

如果你认为人类不能影响世界的气候,那你就是个笨蛋了。例如,有记载的事实是,人造的氟碳化合物在臭氧层中造成了一个巨大的空洞。世界各国在所谓的《蒙特利尔议定书》中达成一致,同意逐步淘汰危害最大的氟碳化合物R-12和R-22。因此,臭氧空洞现在大大缩小了。
科学测量显示,目前的二氧化碳水平高于过去80万年以来的水平,并且随着化石燃料的燃烧,在工业革命初期开始呈指数级增长。燃烧化石燃料的主要副产品是二氧化碳,二氧化碳是一种温室气体,会使地球保持热量。

Since the last glacial maximum around 20,000 years ago the oceans have risen over 120 meters (yes, almost 400 feet)... That's 400 FEET - not inches, not mm, not cm... FEET.
Of course the temperature and oceans will rise faster at some points and slower at others - there are natural cycles that run on various cycles. At this rate by 2100 we should absolutely expect to see approximately 80 (years) * 0.24 inches /year = 19.2" rise in the oceans. That is just an AVERAGE NUMBER...
We may indeed be in a time period of more variant weather with greater storms. This is just part of the normal cycle. Look at the little ice age that occurred just a few hundred years ago. The same reduction in the sun's output is expected to also occur in the future.
We may indeed be helping ourselves to avoid another ice age by allowing the CO2 to build up (cont'd). - UP: 6 DN: 7

自从大约2万年前的最后一次冰川期以来,海平面已经上升了120米(是的,差不多400英尺) ... 那是400英尺,不是英寸,不是毫米,不是厘米... 是英尺。
当然,温度和海洋在某些时候上升得更快,在另一些时候上升得更慢,有各种自然周期在运行。按照这个速度,到2100年,我们绝对有望看到大约80(年) * 0.24英寸/年 = 19.2英寸的海平面上升。这只是一个平均数...
我们可能确实处在一个天气更加多变,风暴更加猛烈的时期。这只是正常周期的一部分。看看几百年前发生的小冰河时期。预计未来也会出现同样的太阳能量减少的情况。
通过让二氧化碳积累起来,我们可能确实在帮助我们自己避免另一次冰河时期的到来。

Elizabeth, Humans have been changing the climate for several thousand years now. There is considerable evidence that human civilizations have existed for over 30,000 years.
However, it has only been since mankind discovered Coal and Oil that he has burned enough of them to more than double the amount of CO2 and CH4 in the atmosphere starting in the late 1500's to 1650's. Use of coal for fuel to warm homes and cook with in the 1700's accelerated its use. Since the beginning of the Industrial Revolution coal use has actually doubled every 15 years.
As for OIL refining, that began in earnest in the mid 1700's as Kerosene in Russia. As the refining process spread it was used to fuel everything from steam engines for plants which made everything from textiles to furniture.
The real question is -- does mankind have the intestinal fortitude to bite the bullet and make the switch to reliable renewables within the next 10 - 15 years and totally end their dependence upon CO2 / CH4 producing products for energy. Personally as a whole, I don't think they do.
As this article points out, the sciences have identified major markers of ice melt. The physics of ice melt is interesting - the more melt the faster what is left melts almost geometrically. - UP: 8 DN: 2

人类已经改变气候几千年了。有相当多的证据表明人类文明已经存在了三万多年。
然而,自从人类发现了煤和石油之后,从15世纪末到16世纪50年代,人类燃烧的煤和石油使大气中二氧化碳和甲烷的含量增加了一倍多。17世纪使用煤作为燃料来取暖和做饭,加速了煤的使用。自工业革命开始以来,煤的使用实际上每15年就增加一倍。
至于石油精炼,在17世纪中期,俄罗斯正式开始使用煤油。随着精炼工艺的推广,它被用于从纺织物到家具等工厂的蒸汽机的各种燃料。
真正的问题是,人类是否有勇气在未来10-15年内咬紧牙关,转向可靠的可再生能源,彻底结束对二氧化碳/甲烷产品的能源依赖。就我个人而言,我不这么认为会这么做。
正如本文所指出的,科学已经确定了冰川融化的主要标志。冰川融化的物理学很有意思,融化得越多,剩下的部分就融化得越快,几乎是几何级数的融化。
