Native herpetology coordinator Alyssa Hoekstra talks about the different types of rattlesnakes in Utah and their important role in our ecosystem. Then, Walt Meier, senior research scientist at the National Snow and Ice Data Center, talks about the current state of arctic sea ice. In March, arctic sea ice was at its lowest ever recorded for that month, measuring six percent below the long-term average.

Greenland is the world's largest island and a self-governed territory of Denmark. About 57,000 people live there, mainly along its coasts. Most of Greenland lies north of the Arctic Circle, under thick sheets of ice. 格陵兰岛是世界上最大的岛屿，也是丹麦的自治领土。大约有 57,000 人居住在那里，主要居住在沿海地区。格陵兰岛的大部分地区位于北极圈以北，覆盖着厚厚的冰层。 The island plays a large part in the weather experienced by billions of people every day and in climate changes around the planet, experts say. 专家表示，该岛在数十亿人每天经历的天气以及全球气候变化中发挥着重要作用。American President-elect Donald Trump is expressing interest in buying Greenland from Denmark. He said something similar during his first term in office as well. The United States has a large military base on the island. 美国当选总统唐纳德·特朗普表示有兴趣从丹麦购买格陵兰岛。他在第一个任期内也说过类似的话。美国在岛上拥有大型军事基地。Geologists say Greenland has huge amounts of oil and natural gas below the ice and valuable elements known as rare earth minerals. Rare earth minerals are needed in communication technologies, including phones. 地质学家表示，格陵兰岛冰层下蕴藏着大量石油和天然气，以及被称为稀土矿物的宝贵元素。通信技术（包括电话）需要稀土矿物。 Most of these resources are trapped under Greenland's ice. However, warming temperatures in recent years have increased melting on the island. As more ice melts, some of these resources may become easier to reach. 这些资源大部分都被困在格陵兰岛的冰层下。然而，近年来气温升高加剧了岛上的融化。随着更多的冰融化，其中一些资源可能会变得更容易获取。 Geoff Dabelko is a security and environment professor at Ohio University. He thinks other countries are becoming interested in Greenland because China is currently the supplier of more than half of the world's rare Earth minerals. 杰夫·达贝尔科 (Geoff Dabelko) 是俄亥俄大学安全与环境教授。他认为其他国家对格陵兰岛越来越感兴趣，因为中国目前是世界一半以上稀土矿物的供应国。From 1992 to 2020, Greenland lost an average of 169 billion metric tons of ice each year, with losses reaching 444 billion metric tons in 2019. 从1992年到2020年，格陵兰岛平均每年损失1690亿吨冰，2019年损失达到4440亿吨。 Mark Serreze is director of the National Snow and Ice Data Center in Boulder, Colorado. He told The Associated Press that melting from Greenland will be a central issue through the 21st century. That is because melting ice adds to rising sea levels. Serreze noted that the amount of melting will likely increase in the future. 马克·塞雷兹 (Mark Serreze) 是科罗拉多州博尔德国家冰雪数据中心的主任。他告诉美联社，格陵兰岛融化将成为整个 21 世纪的一个中心问题。这是因为冰融化会导致海平面上升。Serreze 指出，未来融化量可能会增加。Greenland also serves as the engine for an important ocean current that influences Earth's climate in many ways, including storm activity. The current is called the Atlantic Meridional Overturning Circulation, or AMOC. The current is slowing down because more fresh water from Greenland's melting ice is entering the ocean, Serreze said. 格陵兰岛也是重要洋流的引擎，洋流以多种方式影响地球气候，包括风暴活动。该洋流被称为大西洋经向翻转环流（AMOC）。塞雷兹说，由于格陵兰岛融化的冰越来越多的淡水进入海洋，洋流正在减慢。 A shutdown of the current could lead to long-term freezes in Europe and parts of North America. 电流的关闭可能会导致欧洲和北美部分地区长期冻结。 “If this global current system were to slow substantially or even collapse . . .as we know it has done in the past — normal temperature and precipitation patterns around the globe would change drastically,” said climate scientist Jennifer Francis of the Woodwell Climate Research Center, a non-profit based in the American state of Massachusetts. “如果当前的全球体系大幅放缓甚至崩溃。。“正如我们所知，过去的情况是——全球的正常气温和降水模式将发生巨大变化，”美国马萨诸塞州非营利组织伍德韦尔气候研究中心的气候科学家詹妮弗·弗朗西斯说。 She added that the changes would have very damaging effects on farming and ecosystems. 她补充说，这些变化将对农业和生态系统产生非常破坏性的影响。As more ice melts, Greenland is also changing color from the white of ice to the blue and green of water and land. These darker colors hold more heat from the sun and can increase the speed of warming. 随着更多的冰融化，格陵兰岛的颜色也从冰的白色变为水和陆地的蓝色和绿色。这些较深的颜色会吸收更多来自太阳的热量，并会加快变暖的速度。 Greenland lies in between northern Canada, northern Europe, and Russia. That area may become more valuable to countries if melting in the Arctic Ocean continues to increase and more ships pass through the area. 格陵兰岛位于加拿大北部、北欧和俄罗斯之间。如果北冰洋的融化继续增加并且更多的船只经过该地区，该地区可能对各国变得更有价值。

Permafrost is ground that remains frozen for two years or more. It's made up of soil, rocks and sand, and held together by ice. In some places, this ground layer formed over 100,000 years ago, and can reach several miles in depth. Around 24% of land in the Northern Hemisphere has permafrost underneath it, according to the US National Snow and Ice Data Center. It's mostly found in Arctic countries, in places like Russia, Canada and Alaska. As planet Earth's climate warms, this permafrost is thawing, an alarming situation which is already having a dramatic impact. What's happening to the permafrost then? How does that affect the rest of us who don't live in those regions? In under 3 minutes, we answer your questions!

Une récente étude, dirigée par Seung-Ki Min de l'université de Pohang en Corée du Sud, propose de nouvelles estimations sur la fonte de l'arctique, en se basant sur de nouvelles données. Si l'observation n'est pas nouvelle, elle corrobore, voire confirme les propos du GIEC, (Groupe d'experts intergouvernemental sur l'évolution du climat) qui avait prédit que la région perdrait sa glace estivale d'ici les années 2040. Sauf que cette nouvelle étude est encore plus pessimiste, et suggère que cela pourrait se produire dix ans plus tôt, soit en 2030.Un tel impact de l'activité humaine sur la fonte des glaces sous-entend que les efforts nécessaires pour ralentir le réchauffement climatique ont peut-être été sous-estimés jusqu'à présent. Pour Seung-Ki Min que je cite « nous devons réduire de manière plus ambitieuse les émissions de CO₂ et nous préparer à nous adapter à ce réchauffement plus rapide dans l'Arctique ». En effet, son étude indique que même si la hausse de la température mondiale est limitée à 2 °C, la glace estivale aura disparu d'ici 2050. Parmi les conséquences que cela aura sur notre climat, le chercheur cite notamment "une augmentation des phénomènes météorologiques extrêmes que nous connaissons déjà, tels que les vagues de chaleur, les incendies de forêt et les inondations". Car la fonte des glaces entraîne des modifications de courant, notamment ceux qui contribuent à réguler le climat en Amérique du Nord, en Europe et en Asie.Pour Mark Serreze, directeur du National Snow and Ice Data Center de l'université du Colorado, je cite « le message clé est que nous perdons le contrôle de la banquise » fin de citation. Lui et Min partagent la même vision des choses, la planète se réchauffe beaucoup plus vite que prévu, et dépasser + 2 °C aurait des conséquences encore plus catastrophiques que ce que l'on peut imaginer aujourd'hui.

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”。

英语新闻|北极已经热到穿短袖了？科学家冰天雪地穿短裤打排球…According to Sky News, A heatwave swept across Europe this summer, with unprecedented 32.5C in the Arctic Circle. Climate change projections say that global warming will make these events more likely, with heatwaves growing more intense, more frequent and longer-lasting.据英国天空新闻网报道，今年夏天，热浪席卷欧洲，就连北极圈的温度也一度飙升至32.5摄氏度。气候变化预测表明，全球变暖将使热浪变得更强烈、更频繁、更持久。On July 19, CNN reporter René Marsh appeared on the Greenland News in short sleeves, saying in the video: “It's warm enough to wear short sleeves, near 60 degrees in Greenland.”7月19日，美国有线电视新闻网记者勒内·玛什穿着短袖出现在格陵兰岛新闻中，她在视频中说：格陵兰岛温度接近60华氏度（约15.5摄氏度），像今天这样温暖的天气足以穿短袖了。The ice sheet covering Greenland, the world's largest island, is also melting at an accelerating rate, according to CNN. Scientists in the Arctic can walk around in short sleeves and even play ice volleyball.据CNN报道，覆盖世界第一大岛格陵兰岛的冰盖也在加速融化。北极地区的科学家们可以穿着短袖到处逛，甚至打起了冰上排球。Several days of unusually warm weather in northern Greenland have triggered rapid melting, made visible by the rivers of meltwater rushing into the ocean.连日来异乎寻常的温暖天气，导致格陵兰岛北部的冰盖加速融化，人们可以看到冰融成水后汇成溪流涌入海洋。"Yesterday we could wander around in our t-shirts — that was not really expected," said Kutalmis Saylam, a research scientist with the University of Texas who is currently stationed in Greenland.目前驻扎在格陵兰岛的得克萨斯大学科学家库塔米斯·赛勒姆说，“昨天我们甚至可以穿着T恤到处走动——这真的出乎意料。”The amount of ice that melted in Greenland between July 15 and 17 alone — 6 billion tons of water per day — would be enough to fill 7.2 million Olympic-sized swimming pools, according to data from the US National Snow and Ice Data Center.根据美国国家冰雪数据中心的数据，仅7月15日至17日格陵兰岛每天流失的冰量多达约60亿吨，足以填满720万个奥运会规模的游泳池。Each summer, scientists worry that they will see a repeat of the record melting that occurred in 2019, when 532 billion tons of ice flowed out into the sea. An unexpectedly hot spring and a July heat wave that year caused almost the entire ice sheet's surface to melt. Global sea level rose permanently by 1.5 millimeters as a result.每年夏季，科学家们都非常担心2019年创纪录融化的重演，当年格陵兰岛冰盖融化了约5320亿吨冰，温泉和7月的热浪直接导致全球海平面永久上升达1.5毫米。"Unprecedented" rates of melting have been observed at the bottom of the Greenland ice sheet, a study published in February found, caused by huge quantities of meltwater trickling down from the surface.2月份发表的一项研究发现，格陵兰冰盖底部出现了“前所未有的”融化速度，这是由大量融水从地表滴落造成的。"The temperatures we are seeing right now are simply too hot for the ski-equipped planes to land," Grinsted said. "So we store the ice cores in large artificial caves we have made into the snow to protect it from the heat of the summer."在格陵兰岛西北部的东格陵兰冰核项目研究营地的科学家格林斯特德表示，我们一直在试图让飞机飞到营地，这样他们就可以把最近收集到的冰芯运出营地。但因为温度异常、冰层松软导致飞机无法正常起落。Scientists take advantage of the abnormal warmth while they wait, playing volleyball in their shorts on an ice sheet at the top of the world.而科学家们在等待时，竟趁着异常的温暖天气，穿着短裤在世界之巅的冰原上打起了排球。accelerating英[æk'sæləreɪtɪŋ]；美[æk'sæləreɪtɪŋ]n. 加速adj. 加速的，促进的，催化的v. （使）加快，（使）增速( accelerate的现在分词); 促使…早日发生，促进; [教育学]使（学生）跳级; 提早学完（课程等）permanently英[ˈpɜːmənəntli]；美['pɜːmənəntli]adv. 永久地，长期不变地trickling down英[ˈtrikl daun]；美[ˈtrɪkəl daʊn]向下滴流

What is permafrost? Permafrost is ground that remains frozen for two years or more. It's made up of soil, rocks and sand, and held together by ice. In some places, this ground layer formed over 100,000 years ago, and can reach several miles in depth. Around 24% of land in the Northern Hemisphere has permafrost underneath it, according to the US National Snow and Ice Data Center. It's mostly found in Arctic countries, in places like Russia, Canada and Alaska. As planet Earth's climate warms, this permafrost is thawing, an alarming situation which is already having a dramatic impact. What's happening to the permafrost then?

“For the entire development of modern civilization, Greenland and Antarctica have been holding vast amounts of water as frozen ice and helping us to maintain very steady sea levels around our coast. And that's allowed us to build infrastructure, build mega cities, right on the coast where many of our world's mega cities sit. Now….we're raising our air temperatures …and that's adding more water to our oceans, which is arriving at shores around the world… disrupting the infrastructure we built…(and) caus(ing) health and other problems.” Dr. Twila Moon on Electric Ladies Podcast We hear about melting ice caps as a symbol of global warming. What do they mean? What does the ice caps mean? What does the fact that they're melting mean? And what does it mean for our cities, towns and communities? Listen to Dr. Twila Moon, a climate scientist from and the University of Colorado at Boulder's National Snow and Ice Data Center who specializes in the ice caps - a cryosphere scientist – in this fascinating interview with Electric Ladies host Joan Michelson where she helps us understand what those melting ice caps mean for us. You'll hear about: Why glaciers matter How glaciers melting directly affects our daily lives. Why small changes in air temperature directly affect our infrastructure, food and water supplies. What we can do in our daily conversations to help people understand the impact of climate change. Plus, insightful career advice …. “So first recognizing that you're in a continually evolving space of influence and the dreams that you, that position that you were applying for three years ago, take the time now to consider…(that) you might've already grown out of that dream and already be able to take on bigger responsibilities or bigger roles. And the second thing is learning how to say no saying no is saying yes to the things already on your plate.” Twila Moon on the Electric Ladies podcast Read Joan's related Forbes articles here too.

What A Week   (8/16- 8/22)Intro: (Cue intro music) Hey everyone, welcome back to What a week!, I'm your host, Olivia Lee, here to deliver your weekly dose of the news. Let's get started!In Local News:  https://www.oregonlive.com/portland/2021/08/demonstrators-congregate-at-portland-waterfront.html https://www.theguardian.com/us-news/2021/aug/23/portland-oregon-clashes-protests-proud-boys-antifascistThis past sunday, a rightwing protest in Portland turned into a gunfight, when antifascist demonstrators returned fire at a man who shot at them with a handgun in a downtown street. The firefight took place in the heart of downtown Portland, soon after 6pm on Sunday night. Portland police bureau confirmed that a man had been arrested over the shooting but did not have any information on any injuries. The incident came after a day of protest descended into running clashes involving hundreds of protesters and counterprotesters. This past Sunday's planned gatherings were spurred by a similar event one year ago where right-wing demonstrators, including some affiliated with the Proud Boys, faced off against anti-fascist counter-demonstrators in downtown Portland. The two groups pelted each other with paintballs, mace and rocks as Portland police stayed mainly out of the way. In-state news: https://www.koin.com/news/health/coronavirus/oregon-surpasses-sad-milestone-of-3000-covid-19-deaths/Last Friday, the Oregon Health Authority reported 19 new COVID-related deaths, raising the state's death toll to 3,012. OHA Director Patrick Allen in a statement said, “Today, we mark another sad milestone in the pandemic: Our 3,000th COVID-19 related death. Our sadness is deepened by the realization that these deaths are increasingly preventable. We know that the available vaccines provide a reliable protective shield against serious illness and death from COVID-19. These vaccines are saving lives every day and I urge every Oregonian who has not yet received the vaccine to please make a plan to be vaccinated.” end quote. https://katu.com/news/local/oregon-reports-4700-new-coronavirus-cases-24-more-covid-deaths-over-the-weekendOregon health officials reported more than 4,700 new coronavirus cases and 24 COVID-19 related deaths over the span of this past weekend as the delta variant and hospitalizations continue to surge across the state. The Oregon Health Authority has identified 257,644 presumptive and confirmed coronavirus cases since the pandemic started.  In National News: https://www.npr.org/sections/coronavirus-live-updates/2021/08/23/1030251410/pfizer-covid-vaccine-fda-approvalLast week, The Food and Drug Administration formally approved Pfizer's COVID-19 vaccine. The widely anticipated decision replaces the emergency use authorization granted by the agency last December. The vaccine, developed by Pfizer and its partner BioNTech, is the first COVID-19 vaccine to be subject to a full review by the U.S. regulator and to get an approval that puts the vaccine on par with other marketed vaccines. The full approval could make it easier for employers, the military and universities to mandate vaccination and may reassure some people who are still undecided about getting the vaccine.  https://www.npr.org/sections/coronavirus-live-updates/2021/08/18/1028798003/covid-19-booster-shots-roll-out-september-moderna-pfizerThe country's top health officials announced last Wednesday that COVID-19 booster shots of the Pfizer and Moderna vaccines are set to become available for all U.S. adults beginning next month. Dr. Vivek Murthy, the surgeon general, spoke on this announcement at a White House briefing saying quote,  "We know that even highly effective vaccines become less effective over time. It is now our clinical judgment that the time to lay out a plan for COVID boosters is now.”    In International News:  ​​https://www.cnn.com/2021/08/23/china/china-zero-case-delta-intl-hnk/index.htmlLast week China reported no new locally transmitted Covid-19 cases for the first time since July, according to its National Health Commission (NHC), as authorities double down on the country's stringent zero-Covid approach. China has been grappling with the spread of the highly contagious Delta variant since July 20, when a cluster of Covid-19 infections were detected among airport cleaning staff in the eastern city of Nanjing. Since then, it has catapulted into the worst outbreak China has seen since 2020, spreading to more than half of the country's 31 provinces and infecting more than 1,200 people. The surging cases driven by Delta were seen as the biggest challenge yet,  to China's uncompromising zero tolerance virus policy. Local authorities responded by placing tens of millions of residents under strict lockdown, rolling out massive testing and tracing campaigns and restricting domestic travels. The strict measures appear to be working as  daily infections have fallen steadily over the past week into single digits, down from more than 100 from its peak two weeks ago. Lastly here is the wildcard news for the week: https://www.npr.org/2021/08/20/1029633740/rain-fall-peak-of-greenland-ice-sheet-first-climate-changeGreenland saw rain at the highest point of its ice sheet for the first time since scientists have been making observations there. According to the U.S. National Snow & Ice Data Center, rain fell for several hours on an area 10,551 feet in elevation on Aug. 14, an unprecedented occurrence for a location that rarely sees temperatures above freezing. It was also the latest date in the year scientists had ever recorded above-freezing temperatures at the National Science Foundation's Summit Station. The rainfall coincided with the ice sheet's most recent "melt event," in which temperatures get high enough that the thick ice begins to melt.  Closing:  Well that wraps up What a Week! Stay safe and see you guys next week. 

This episode features Dr. Matthew Druckenmiller from the National Snow and Ice Data Center and Director for the Navigating the New Arctic Community Office–both hosted at CU Boulder. We'll hear about how his family-centered upbringing in rural Pennsylvania formed the foundations for his lifelong work exploring the relationships between the physical environment and the communities–especially indigenous communities–that dwell there. *Intro and outro music by the artist, Broke for Free.

On This Green Earth , Nell and Chris take a closer look at Arctic Sea Ice. The Arctic Sea Ice reached its maximum surface area around the middle of March this year. What was the extent of its coverage, and how much of it has already begun to melt due to the combination of natural and man-made warming? Walt Meier, senior research scientist at the National Snow and Ice Data Center comes on the show to answer these questions.

In this episode of This Green Earth, Walt Meier, Senior Research Scientist with the National Snow and Ice Data Center is the guest. The center provides updates on the growth and conditions of sea ice up in the Arctic and Walt talks about why the year 2020 saw a near record level of sea ice melt.

On this episode of This Green Earth Walt Meier of the National Snow and Ice Data Center joins the show. He talks with Chris and Nell about the record amount of sea ice that has melted this past summer up in the Arctic Ocean, how close open water is to the North Pole and, the role climate change is playing in that annual event.

Walt Meier with the National Snow and Ice Data Center joins Nell and Chris on This Green Earth to talk about Arctic Sea Ice, it's maximum extent this past March and how much has melted since then. He also provides some information on what Arctic-based research is being impacted by COVID-19.

In this episode: We meet Dr. Ulyana Horodyskyj, a glaciologist, geologist, climatologist, and planetologist. After earning her PhD, she went on to complete postdoctoral research at the National Snow and Ice Data Center and launched an adventure and citizen science company called Science in the Wild, which offers participants the chance to go on expeditions and collect scientific data. Ulyana is also an instructor for a citizen science program called Project PoSSUM (Polar Suborbital Science in the Upper Mesosphere), and a visiting professor of environmental science at Colorado College.  In this conversation, Ulyana discusses how she first got interested in space and science, the meaning of “citizen science,” and shares her experiences as commander of a deep space mission simulation as a part of NASA’s Human Exploration Research Analog (HERA XII) project. She also describes the similarities between working at high mountain elevations and being an astronaut in space, offers advice for women trying to get into scientific professions, and explains what her ideal mission destination would be if she were to be selected for the upcoming NASA class for which she is an applicant. In discussing her research work in high mountain elevations such as the Nepal Himalayas, Ulyana says, “Twenty [thousand] to 23,000 feet is the kind of the realm I've been working in, and you still have to function in order to collect samples for the research. I think I really just enjoy both the physical and mental challenges that come along with the high-altitude climbing and the science.” For more information about Ulyana's Science in the Wild initiative, visit www.scienceinthewild.com.

Mark Serreze, director of the Snow and Ice Data Center in Boulder, Colorado, joined guest host Peter Shurman to discuss.

Nella sola giornata si sono sciolte circa 2 miliardi di tonnellate di ghiaccio, sul 40% del territorio dell'isola. Lo hanno riportato i siti di Washington Post e Cnn, citando i dati del National Snow and Ice Data Center. Questo scioglimento record è stato causato da temperature al di sopra della media della tarda primavera. «Lo scioglimento dei ghiacci» come spiega l'ANSA «è un fenomeno naturale in Groenlandia nella bella stagione. Di norma però il picco si ha fra giugno e agosto, mentre quest'anno lo scioglimento è cominciato già ad aprile».

In this week’s episode, we talk with Twila Moon, a research scientist at the National Snow & Ice Data Center out of the University of Colorado Boulder. We discuss her work in ice dynamics and ice sheet-ocean interaction as well as the Wheelhouse Institute, an organization she helped found that focuses on sharing skills, power, and networks to affirm and amplify visionary women's leadership.

In this episode of ThinkArctic, we speak with Walt Meier, senior research scientist at the National Snow and Ice Data Center, about the changing sea ice in the Arctic.

The temperature in the Arctic Circle in northern Sweden has reached 30°C. In northernSiberia, temperatures reached 32°C at the beginning of this month. In the same period of the previous year, the average temperature in this area was only 10°C. According to the monitoring data of the National Snow and Ice Data Center, theabnormal high temperature further aggravated the melting of sea ice in the Arctic Circle this summer. Among the Nordic coast and northwestern Russia, sea ice has shown an unusually low trend. The reduction of sea ice not only threatens the survival of creatures such as polar bears, but also further aggravates the abnormal weather in the northern hemisphere.在瑞典以北的北极圈，气温已经达到了30°C，八月的开始，西伯利亚的北部气温已经达到32°C。然而，往年这一时期，这些地区的平均温度也只是10°C。根据国家冰雪数据中的监测数据显示，今年夏天异常的高温天气使得北极圈海冰消融情况更加严重。北欧海岸以及俄罗斯西北部海冰平面已经呈现较低趋势。海冰的减少不仅威胁到了北极熊这些生物的生存，也使得北半球的异常天气更加常见。1.Sweden /'swidən/ 瑞典2.Siberia /sai'biəriə/西伯利亚3.average/'ævərɪdʒ/平均的Eg: the average price 平均价格4.abnormal /æb'nɔːml/ 不正常的，反常的Eg:abnormal behavior 反常行为5.aggravate/'ægrəveɪt/ 使加重；使恶化Eg:The bad weather aggravated his illness.坏天气加重了他的病情。6.hemisphere /'hemɪsfɪə/ 半球Eg:the Northern hemisphere 北半球

We all may prefer the goldilocks zone – not too hot, not too cold. But most of the universe is bitterly cold. We can learn a lot about it if we're willing to brave a temperature drop. A chilly Arctic island is the closest thing to Mars-on-Earth for scientists who want to go to the Red Planet. Meanwhile, the ice sheet at the South Pole is ideal for catching neutrinos – ghostly particles that may reveal secrets about the nature of the universe. Comet ISON is comet ice-off after its passage close to the Sun, but it's still giving us the word on solar system's earliest years. Also, scientists discover the coldest spot on Earth. A champion chill, but positively balmy compared to absolute zero. Why reaching a temperature of absolute zero is impossible, although we've gotten very, very close. Guests: Francis Halzen – Physicist, University of Wisconsin-Madison, principal investigator of The IceCube Neutrino Observatory Ted Scambos – Glaciologist, lead scientist, National Snow and Ice Data Center, University of Colorado Pascal Lee – Planetary scientist, SETI Institute, director, NASA Haughton-Mars Project, and co-founder of the Mars Institute.
