Modelling channelized surface drainage of supraglacial lakes

first_imgSupraglacial lakes can drain to the bed of ice sheets, affecting ice dynamics, or over theirsurface, relocating surface water. Focusing on surface drainage, we first discuss observations of lakedrainage. In particular, for the first time, lakes are observed to drain >70 km across the Nivlisen iceshelf, East Antarctica. Inspired by these observations, we develop a model of lake drainage through achannel that incises into an ice-sheet surface by frictional heat dissipated in the flow. Modelled lakedrainage can be stable or unstable. During stable drainage, the rate of lake-level drawdown exceeds therate of channel incision, so discharge from the lake decreases with time; this can prevent the lake fromemptying completely. During unstable drainage, discharge grows unstably with time and alwaysempties the lake. Model lakes are more prone to drain unstably when the initial lake area, the lake inputand the channel slope are larger. These parameters will vary during atmospheric-warming-inducedablation-area expansion, hence the mechanisms revealed by our analysis can influence the dynamicresponse of ice sheets to warming through their impact on surface-water routing and storage.last_img read more

FirstEnergy’s Move to Shift Risk to Ratepayers in West Virginia

first_imgFirstEnergy’s Move to Shift Risk to Ratepayers in West Virginia FacebookTwitterLinkedInEmailPrint分享Andrew Brown for the Charleston Gazetee-Mail:The president and CEO of FirstEnergy suggested in an earnings call Wednesday that the company would seek to sell the Pleasants Power Station near St. Marys to its West Virginia subsidiaries — a move that would shift the cost and risk of that coal-powered plant from company shareholders to customers.The earnings call follows several weeks in which FirstEnergy, the parent company of MonPower and Potomac Edison, has been heavily questioned about its integrated resource plan — a 15-year energy forecast that was filed with the state Public Service Commission earlier this year. That document suggested that MonPower would seek to buy an existing, unnamed coal-fired power plant in the near future.Two environmental groups, the West Virginia Citizen Action Group and the Sierra Club, suspected that the plan was meant to set up FirstEnergy to shift the Pleasants plant off FirstEnergy’s books and onto MonPower and Potomac Edison ratepayers. The company also submitted a chart to the PSC that had the Pleasants planted listed alongside all of the other power plants owned or contracted by MonPower.In an April 2016 report by UBS, an investment bank, electric utility analysts suggested FirstEnergy would likely seek to move the Pleasants plant into a regulated marketplace, especially since the company had already spent $650 million on systems to reduce nitrogen oxide and sulfur dioxide emissions from the plant.But lawyers for the Sierra Club, the Citizen Action Group and the PSC staff have all questioned whether buying another coal-fired plant is the cheapest option for customers, and they’ve asked why FirstEnergy didn’t take into account possible regulations on carbon emissions from power plants. The naming of the Pleasants plant will likely only add to the opposition that has been building in recent months against the resource plan.James Van Nostrand, a West Virginia University law professor who has represented utilities in other states, said the fact that FirstEnergy already has the Pleasants plant listed alongside MonPower’s existing electricity sources may suggest company officials created the resource plan — which is supposed to be an objective analysis of future energy markets — so it could justify offloading the Pleasants plant.Still, with regional energy markets being flooded with cheap electricity from natural gas turbines and renewable energy sources that continue to decline in price, Van Nostrand said it makes sense that FirstEnergy executives want to sell the plant to a West Virginia subsidiary.In the regional market, known as the PJM Interconnection, the plant only makes money if it produces electricity at a cheaper price than other power sources all over the East Coast. If FirstEnergy can get the PSC to approve MonPower’s takeover, however, the company is able to guarantee a profit from West Virginia customer rates.“FirstEnergy has a fiduciary obligation to maximize return for its shareholders, but that is where the PSC comes in,” Van Nostrand said. “This is a corporate bailout. Bad management decisions should have consequence for shareholders and management.”FirstEnergy’s resource plan and the lead up to the Pleasants plant actually being named, Van Nostrand said, reminds him of the regulatory process that occurred before MonPower took over the Harrison power plant near Shinnston in 2013 — an acquisition that customers are still paying for.Full article: FirstEnergy CEO says Pleasants power plant sale may happenlast_img read more

Mexican Cartels Obtain Weapons From Central American Arsenals

first_imgBy Dialogo April 07, 2011 Mexican drug cartels are obtaining military-type weapons from arsenals left over from civil wars and conflicts in Central America, the head of the U.S. Southern Command, Gen. Douglas Fraser, affirmed. “Over 50% of the military-type weapons that are flowing throughout the region have a large source within Central American stockpiles (…), left over from wars and conflicts in the past,” Fraser indicated during a U.S. Senate hearing. In another appearance last week, Fraser identified the existence of between 45 and 80 million weapons in Central America, many of them left over from the conflicts of past decades. “There are (…) weapons coming into Mexico from other parts of Latin America,” the head of the Northern Command, Adm. James Winnefeld, warned for his part. “There are certain types of weapons that might come from south of Mexico,” Winnefeld said. U.S. authorities have made “a lot of focused efforts” in working to control the Central American arsenals, Fraser said. “But there’s a lot of funding available with these transnational criminal organizations, so corruption, slack processes are still a problem,” Fraser said. A number of sophisticated pieces of military equipment used by Mexican drug cartels, such as night-vision goggles, are of unknown origin, Winnefeld noted. The cartels “are getting more and more sophisticated,” he admitted. Nevertheless, these groups do not “pose an existential threat to the government” led by Felipe Calderón, since “they don’t have political ambitions,” the admiral said. The military commander praised the progress made by the military and police in Mexico in their fierce fight against the cartels. “I believe that the opportunity exists, if we can support them properly, if they can continue the progress that they’re making, that they can turn the corner on this, but it still remains to be seen,” Winnefeld concluded.last_img read more

Peacekeeping Missions Are a Way of Promoting Human Rights

first_imgBy Marcos Ommati/Diálogo October 23, 2017 The South American Defense Conference 2017 (SOUTHDEC) was held from August 22th to 24th in Lima, Peru, where Diálogo spoke with Army General Juan José Saavedra Fernández, the chief of Uruguay’s Defense General Staff. Gen. Saavedra talked about women’s integration into the Uruguayan Armed Forces and the international recognition that Uruguay enjoys due to its historic contribution to United Nations peacekeeping missions.Diálogo: Is the Uruguayan Defense General Staff equivalent to the general staffs of other nations?Army General Juan José Saavedra Fernández, chief of Uruguay’s Defense General Staff: Practically, yes. The [Uruguayan] Defense General Staff is an organization that was established just a few years ago; six, to be exact. A new law, the Defense Framework for the Uruguayan Armed Forces, came to replace what was previously the Joint Chiefs of Staff. The important thing is that it was given a higher rank. The Defense General Staff is at the same level as the commanders of each military service branch, which is why it has the same hierarchy as the commanders of the Uruguayan Armed Forces—–the commander of the Navy is its fleet admiral, the commander of the Air Force is its general, and the commander of the Army is an Army general. Therefore, the director of the General Staff can be a general officer of any service branch. The Defense General Staff is the highest military advisory organization within the Ministry of Defense.Diálogo: What is missing, or what is the next step for countries to put the information sharing pieces together to more efficiently combat these new threats?Gen. Saavedra: I think that, first, there have to be very clear and specific objectives, because everything is fine in these kinds of meetings, but there is a lot of talk, almost academic, at the theoretical level—. So things need to be brought down to earth. And when we talk about the specifics, we realize that our challenges are the same, they’re similar for the entire hemisphere. I think what we’re lacking is to clearly define what the challenges really are—which ones are our shared objectives—and setting timelines for them, because obviously, these are nations in a dynamic world where governments change, objectives change, and situations change. But on specific issues, I think there are objectives that can be established on the basis of important cases that are of use to us and that engender trust for sharing information in every sense. Today, there are targets such as terrorist threats, the kind of terrorism that’s hitting hard in all corners of the world, knocking on everyone’s door. I think it’s a target that we all need to be fighting and sharing information in that regard. It seems to me that there’s been progress, but that we still have challenges to overcome.Diálogo: There is a lot of discussion about these new threats. For some countries, drug trafficking and cyberattacks are among them. Which of these new threats does Uruguay face?Gen. Saavedra: I think that all of these problems, such as organized crime, or these new threats, as they are called, are evolving so quickly that even though we may not see them as being such palpable threats today, they have to be taken into account. I believe it is the responsibility of the political and military leadership in every country that we give them the importance they deserve and that we work in a comprehensive way to confront them, preparing ourselves for them—–and in addition to preparing ourselves, that we achieve something else that’s quite important, which is prevention and deterrence. That is an essential piece of it: making the potential enemy—the threat—see that it’s not worth traveling to our countries, because we’re going to fight and we’re going to beat them.With respect to cyberdefense, that’s a problem that has been evolving quite rapidly, just like everything else having to do with cyberspace. Those of us who are of a certain age are surprised by the new things cropping up there. They are palpable, and they are the new reality. Uruguay is facing that. A new cyberdefense division within the Ministry of Defense has been established. There are commercial activities that are very important to Uruguay—everything related to ranching and food production—which are based on data that is stored and kept on file. We have to protect those interests and give them importance. That level of coordination among different countries already exists. For example, we already have functioning coordination with the United States. As with anything, it could be improved and refined, but I think we need to stick with it, continuing our coordination and working together. It’s a matter of trust. There are shared goals that are important to other nations. We have to make them clear. It’s important to define them, make them clear, and trust each other. That’s the direction in which we need to work.Diálogo: What progress is being made on the issue of gender inclusion in the Uruguayan Armed Forces?Gen. Saavedra: We understand that the role of women in modern society is fulfilling the same role as men. Meaning that when we talk about gender, they have the same obligations and the same rights, of course. The Uruguayan Army and the Uruguayan Armed Forces were the first in the region to authorize and integrate women into all units, as pilots, officers and sailors, or as infantry and cavalry officers—which are the most complex branches—and in artillery, engineering and communications. And today, they keep advancing in their careers without any problem. We already have women filling command positions in combat units and performing the same duties as the men. We feel that that should continue as-is. And besides, our experience—for example in peacekeeping missions, something that is characteristic of the Uruguayan Armed Forces—has been very positive. Having women in peacekeeping missions has allowed us to get closer to the people we’re trying to assist, providing them the security that is so important for them to be able to achieve peace.Diálogo: It could be said that women are the face of Uruguayan peacekeeping missions, could it not?Gen. Saavedra: Yes. For the Uruguayan Armed Forces, it’s a point of pride that our female personnel have been in these missions and that they have been participating fully in them. We’ve been saying that women and men alike are carrying out the same duties in an egalitarian way, and because we participate in peacekeeping missions with other nations—many of them with different cultures in which women are not so integrated—we have emphasized that as an opportunity [to promote women’s integration into the Uruguayan Armed Forces]. For us, it’s an honor to have women taking part in peacekeeping missions and in all the activities of the Uruguayan Armed Forces.Diálogo: With the end of the United Nations Stabilization Mission in Haiti (MINUSTAH), will the Uruguayan service members who are participating in that mission be deployed elsewhere?Gen. Saavedra: Yes. We like to say that collaborating in peacekeeping missions is our vocation. Some years ago, around 1990, in Cambodia, our first deployment was an odyssey for Uruguay. Traveling 28,000 kilometers to the border with Laos was a real exploit. From that moment, we found that we had an opportunity. Since 1993, we have proudly served in missions in Africa, where we are currently present, and today, mainly in the Congo. Everything that we might collaborate on has added to the professional development and personal development of all members of the Uruguayan Armed Forces, across all three service branches, and we feel that it’s good to continue this. Right now in the United Nations, there are new regulations regarding these new deployments. We’re working to come up to speed on that, and we’re seeing what we can do to be more efficient and how we can better work together in new peacekeeping missions in Africa; missions that are certainly more complex and that belong to a new generation, requiring us not only to have special professional training but also a different awareness. We’re working in that regard, and we’re optimistic that by next year we’ll be able to be on the other side, working together in missions and collaborating on peacekeeping, which is somewhat difficult.Diálogo: How do the Uruguayan Armed Forces deal with the issue of human rights in peacekeeping missions?Gen. Saavedra: We feel that one way of promoting human rights is precisely to be in peacekeeping missions. We go to countries where human rights were violated for centuries—–women’s rights and children’s rights. We all know about issues like child soldiers and human trafficking… Peacekeeping missions are a tool that has proven to be useful for promoting human rights, for promoting gender equality, for promoting stabilization in societies that have gone through hard, sad, and difficult times, such as wars, so that they are able to move forward and so that those societies make advances in their own progress, in their own development. One fact that is very important is the full force of human rights. In that regard, we are convinced that we need to go back to the countries where we’ve been throughout the past 17 years—Cambodia, Mozambique, Angola, and even Congo—and also where we’ve been as observers—Rwanda, Sierra Leone, Liberia—to see how they’ve advanced. Even though they haven’t managed to solve all their problems—hardly any nation is able to completely achieve that—they’re headed in that direction, just as we all are. Somehow we’ve contributed to that happening, and we take pride in having done so and in being able to keep doing so.last_img read more
