 Countries Urge Increased International Research in the Arctic. A joint statement from countries with interests in the Arctic emphasizes the need for scientific collaboration in this rapidly changing region but sidesteps attributing climate change to human activities... Another U.S. delegation member, Fran Ulmer, chair of the U.S. Arctic Research Commission, an independent agency based in Arlington, Va., said that the results of the meeting are "less about the statement and more about the commitment that these countries are making to the investment in Arctic research, Arctic cooperation and collaboration, and how that will benefit the decision makers, be they in government or in the private sector."

Why a Warmer World May Equal a Wetter Arctic. As the Arctic warms, it's predicted to get wetter. But why? A new study looks to history for answers, examining what happened in the region during a period of warming some 8,000 years ago. The research finds evidence that in this ancient time, western Greenland became more humid, a trend often linked to increased precipitation. The study further shows that two different climactic processes may have contributed to this elevated humidity.

 Extra Arctic Observations Can Improve Hurricane Forecasts. Japanese scientists and their international partners have found that additional weather observations in the Arctic can help predict the track and intensity of tropical and mid-latitude cyclones more accurately, improving weather forecasting of extreme weather events. Their findings were published on August 14th in Science Reports. Upper-level observations such as radiosondes (weather balloons) in the Arctic can help to forecast mid-latitude extreme events. Impacts of the Arctic observations can transfer via the tropospheric polar vortex, which is massive low-pressure air mass over the Arctic or Antarctic regions at about 6 miles (10-km) altitude.

Effects of Temperature on Fish Sex Determination: Potential Bioindictators of Global Climate Change, November 1, 2018 (Webinar). This is part of the OneNOAA Science Seminar Series. Sex determination in several fishes such as those from Atheriniform families is strongly dependent on the water temperature experienced during early life (so-called temperature-dependent sex determination or TSD). In recent years, water temperature change due to climate change has been concerning on a world-wide level. Fish that have TSD are expected to be seriously affected (e.g. extreme unbalanced sex ratios). Our recent studies have shown that some Atheriniform species possess a major, if not master, testis determining gene, the Y-chromosome-linked anti-Müllerian hormone (amhy). This discovery now makes it possible to detect mismatches (sex reversals) between genotypic (XX or XY) and phenotypic (ovary or testis) sex and demonstrate effects of temperatures on sex determination in wild populations. Using such high temperature sensitivity in sex determination/differentiation and the Y-chromosome linked gene marker, we have been working to establish Atheriniform fish species as bioindicators for the impacts of global warming/climate change on fish reproduction worldwide.

Coastal Wetlands Reduce Disaster Risk, Protect Biodiversity, and Promote Human Health and Well-Being, November 6, 2018 (Webinar). This is part of the OneNOAA Science Seminar Series. There is substantial, growing literature that details positive human health effects, psychological and physiological, of exposure to "nature," including "green" and "blue space," with evidence suggesting that diversity of species or environments may have specific positive human health benefits. These health benefits are important ecosystem services provided by healthy ecosystems. In this presentation, we discuss several critical ecosystem services provided by wetlands including disaster risk reduction, with an emphasis on benefits to human health and well-being. Impacts to human health via damage to ecosystem services from disasters have rarely been considered in disaster planning or mitigation, nor have the health benefits been part of the framework for planning urban greenspaces and land-use. Coastal wetlands can be part of "natural and nature-based" solutions, minimizing the impacts of disasters by buffering coastal communities from storms and erosion and absorbing flood waters. In addition, mental and physical health benefits of experiencing healthy wetlands could offset some stress and disease encounters related to disasters.

ArcticNet: Annual Scientific Meeting 2018, December 10-14, 2018 (Ottawa, ON Canada). Canada's North is experiencing unprecedented change in its sea and terrestrial ice, permafrost and ecosystems under the triple pressures of climate change, industrialization and modernization. The impacts of these pressures can be seen on food and energy security, shipping, sovereignty, northern community health and well-being, and sustainable development and resource exploitation. All these issues have brought the North to the forefront of national and international agendas. Building on the success of its previous Annual Scientific Meetings and International Arctic Change Conferences, the Arctic Network of Centers of Excellence announces the 14th ArcticNet Annual Scientific Meeting.
