A recently released study says the average yearly temperature on Greenland has increased by 1.5 degree Celsius above the average for the 20th century for a 15-year period ending in 2011. Scientists used examples of Greenland’s ice to get information about temperatures from hundreds of years in the past. Until recently, Greenland’s ice cores had not shown a clear sign of warming on the remotest north-central part of the island. Those findings were based on cores from 1995. Researchers involved in the recent study examined cores that were drilled in 2011. They said their work showed a rise in temperature in the previous 15 years. The German researchers published their study in Nature.

最近发布的一项研究表明，在截至 2011 年的 15 年里，格陵兰岛的年平均气温比 20 世纪的平均气温高 1.5 摄氏度。过去。直到最近，格陵兰岛最偏远的中北部地区的冰芯还没有显示出明显的变暖迹象。这些发现基于 1995 年的岩心。参与最近研究的研究人员检查了 2011 年钻探的岩心。他们说，他们的工作表明过去 15 年温度有所上升。德国研究人员在《自然》杂志上发表了他们的研究。

Maria Hoerhold, the study's lead writer, said this a clear signal of climate change. “We keep on (seeing) rising temperatures between 1990s and 2011,” she said. Hoerhold is a glaciologist at the Alfred Wegener Institute in Germany. “We have now a clear signature of global warming.”↳ Scientists take years to study ice core data. Hoerhold has new cores from 2019. But she has not finished studying them. She expects the temperature rise to continue. The study said Greenland's ice sheet and glaciers have been melting.

该研究的主要作者 Maria Hoerhold 表示，这是气候变化的一个明显信号。 “从 1990 年代到 2011 年，我们一直（看到）气温上升，”她说。 Hoerhold 是德国阿尔弗雷德韦格纳研究所的冰川学家。 “我们现在有了全球变暖的明显迹象。”↳ 科学家们花了数年时间研究冰芯数据。 Hoerhold 从 2019 年开始有了新的核心。但她还没有完成对它们的研究。她预计气温会继续上升。该研究称，格陵兰岛的冰盖和冰川一直在融化。

Information from ice cores has been used to estimate temperatures in Greenland from the year 1000 to 2011. Scientific models suggest average temperatures fell a little for the first 800 years of that period. Temperatures then increase a little and then go down until a sudden increase from the 1990s until 2011. The increase in temperatures after 1995 was much larger than pre-industrial times before the mid-19th century. There is an “almost zero” chance that it is anything but human-caused climate change, Hoerhold said. Hoerhold said Greenland’s natural weather changes in the past had hidden human-caused climate change. But, as of about 25 years ago, the warming became too big to be hidden, she said.

来自冰芯的信息已被用于估计格陵兰岛从 1000 年到 2011 年的温度。科学模型表明，该时期的前 800 年平均温度略有下降。从 1990 年代到 2011 年，气温略有上升，然后下降，直到突然上升。1995 年之后的气温上升幅度远大于 19 世纪中叶之前的工业化前时期。 Hoerhold 说，这不是人为造成的气候变化的可能性“几乎为零”。霍尔霍尔德说，格陵兰岛过去的自然天气变化隐藏了人为造成的气候变化。但是，大约 25 年前，变暖变得太大而无法隐藏，她说。

Scientists say past data shows that Greenland is not warming as fast as the rest of the Arctic, the extreme northern part of the world. Some scientists suggest the temperature of the Arctic is now increasing at a rate four times faster than the average world temperature is. Hoerhold and scientists not involved in the research said the new warming data is bad because Greenland’s ice is melting. The study ends with data from 2011. Hoerhold said that, in the following year, a lot of ice melted across Greenland, and the island’s ice loss has been high since then.

科学家们说，过去的数据表明，格陵兰岛变暖的速度不如北极其他地区，即世界最北部地区。一些科学家认为，北极的温度现在正在以比世界平均温度快四倍的速度上升。 Hoerhold 和未参与该研究的科学家表示，新的变暖数据很糟糕，因为格陵兰岛的冰层正在融化。该研究以 2011 年的数据结束。Hoerhold 说，第二年，格陵兰岛上的大量冰融化，此后岛上的冰流失量一直很高。

Jason Box is a scientist with the Danish Meteorological Institute. He said, “We should be very concerned about North Greenland warming because that region has a dozen sleeping giants in the form of wide tidewater glaciers and an ice stream.” As temperatures continue to get warmer, more ice will melt in Greenland, he said. Twila Moon is a scientist with the U.S. National Snow and Ice Data Center. Melting glaciers in Greenland means “rising seas that threaten homes, businesses, economies and communities," she said.

Jason Box 是丹麦气象研究所的科学家。他说：“我们应该非常关注北格陵兰岛变暖，因为该地区有十几个沉睡的巨人，以宽阔的潮水冰川和冰流的形式出现。”他说，随着气温继续变暖，格陵兰岛将有更多的冰融化。 Twila Moon 是美国国家冰雪数据中心的科学家。她说，格陵兰岛冰川融化意味着“海平面上升威胁着家庭、企业、经济和社区”。
