0Australian Alps face world’s largest loss of snow by end of century, research shows
研究显示，到本世纪末澳大利亚阿尔卑斯山面临最大积雪消融量
Study of global heating finds snowfall in Victoria and New South Wales could decline much faster than in other alpine areas around the world
全球变暖研究发现，维多利亚州和新南威尔士州的降雪量下降速度可能比世界其他高山地区快得多
Global heating will cause snow cover in the Australian Alps to decline by 78% by the end of the century – much faster than the declines assessed in six other major skiing regions, new research has found.
新研究发现，到本世纪末，全球变暖将导致澳大利亚阿尔卑斯山积雪减少 78%，远快于其他六个主要滑雪区。
The study published today by researchers from Germany’s University of Bayreuth cautioned about the quickening consequences of the climate crisis, predicting 13% of ski areas across the globe may lose all natural snow cover in a future with high emissions. “Within this century, ongoing climate change will globally lead to a substantial reduction in annual snow cover days in current ski areas under all emissions scenarios,” the study said. “We project a considerable increase in ski areas completely lacking snow in the future.”
在今日发表的研究中，德国拜罗伊特大学研究人员对气候危机的加速后果提出了警告，预测在未来高排放的情况下，全球13%的滑雪场可能会失去所有天然积雪。 “在本世纪内，无论碳排放情况如何，持续的气候变化将导致全球范围内现有滑雪场的年均积雪日数大幅减少，”研究称，“完全无雪的滑雪场预计将大幅增加。”
The study focused on seven major mountainous skiing regions, including the European Alps, Andes, Appalachian Mountains, Australian Alps, Japanese Alps, Southern Alps, and Rocky Mountains. For each it assessed the consequences of three climate change scenarios: “low” “high” and “very high” emissions. Under all three, annual snow cover days across the seven major mountain areas with downhill skiing will significantly decrease worldwide. “Under a high emissions scenario, ski areas in the southern hemisphere … will be most severely affected by climate change,” the study reads.
该研究重点关注七个主要山地滑雪地区，包括欧洲阿尔卑斯山、安第斯山脉、阿巴拉契亚山脉、澳大利亚阿尔卑斯山、日本阿尔卑斯山、南阿尔卑斯山和落基山脉。对于每个地区，该研究评估了三种气候变化情景下的后果：“低排放”、“高排放”和“非常高排放”。在这三种情况下，全球七大高山滑雪地区的年积雪天数都将显着减少。研究报告称：“在高排放情况下，南半球的滑雪场受到气候变化的影响最为严重。”
Australia ’s 78% rate of decline ranks by far the highest of the major skiing regions assessed, which include the European Alps at 42%, Japanese Alps at 50% and Southern Alps of New Zealand at 51%. Ski areas located in highly populated areas are predicted to be more affected by global warming, the study said, adding that the economic profitability of ski resorts around the globe may fall as a consequence of the decline in snow cover.
在迄今为止对主要滑雪区的评估中，澳大利亚阿尔卑斯山以78%的融雪率居首位，此外还包括欧洲阿尔卑斯山（42%）、日本阿尔卑斯山（50%）和新西兰南阿尔卑斯山（51%）。该研究称，预计位于人口多地区的滑雪场将更容易受到全球变暖的影响，并补充说，由于积雪减少，全球滑雪场的经济盈利能力可能会下降。
The study anticipated technical and management strategies like artificial snow making will presumably not be a sufficient compensation measure under a severe climate change scenario, despite being widely used at present to alleviate snow scarcity. “Snow resorts may need to move or expand into less populated mountain areas at higher elevations to combat the effects of climate change,” the study found. “These findings are socioeconomically and ecologically concerning.”
该研究预计，尽管人工造雪等技术和管理策略目前已被广泛用于缓解雪量短缺，但鉴于如此严重的气候变化，这可能不足以作为补偿措施。“滑雪场可能需要搬迁或扩张到海拔较高、人口较少的山区，以应对气候变化的影响，”研究发现，“这些发现在社会经济和生态方面都令人担忧。”
That’s because strategies such as slope contouring, landscaping, and developing new ski areas on north facing and higher elevated slopes are considered threats to nature and the unique mountainous biodiversity. While skiing and its touristic value are of great importance for local economies, “biodiversity in mountainous areas is already heavily affected by global warming,” the study said.
这是因为斜坡轮廓勾勒、景观美化以及在朝北和更高的斜坡上开发新滑雪场等策略是对自然和独特山区生物多样性的威胁。研究称，虽然滑雪及其旅游价值对当地经济非常重要，但“山区的生物多样性已经受到全球变暖的严重影响”。
