Millennial changes in North American wildfire and soil activity over the last glacial cycle

first_imgClimate changes in the North Atlantic region during the last glacial cycle were dominated by the slow waxing and waning of the North American ice sheet as well as by intermittent, millennial-scale Dansgaard–Oeschger climate oscillations. However, prior to the last deglaciation, the responses of North American vegetation and biomass burning to these climate variations are uncertain. Ammonium in Greenland ice cores, a product from North American soil emissions and biomass burning events, can help to fill this gap. Here we use continuous, high-resolution measurements of ammonium concentrations between 110,000 to 10,000 years ago from the Greenland NGRIP and GRIP ice cores to reconstruct North American wildfire activity and soil ammonium emissions. We find that on orbital timescales soil emissions increased under warmer climate conditions when vegetation expanded northwards into previously ice-covered areas. For millennial-scale interstadial warm periods during Marine Isotope Stage 3, the fire recurrence rate increased in parallel to the rapid warmings, whereas soil emissions rose more slowly, reflecting slow ice shrinkage and delayed ecosystem changes. We conclude that sudden warming events had little impact on soil ammonium emissions and ammonium transport to Greenland, but did result in a substantial increase in the frequency of North American wildfires.last_img read more

NextDecade to optimise Rio Grande LNG project to cut emissions

first_img NextDecade will vacate train 6 at the project. (Credit: Carlo San/FreeImages) US-based LNG development company NextDecade has announced that it optimising its Rio Grande LNG project (RGLNG) in the US, to reduce carbon dioxide equivalent (CO2e) emissions.The firm said that the actual front-end engineering and design for RGLNG was based on six LNG trains each capable of producing 4.5 million metric tonnes per annum (mtpa) of LNG for export.It has identified many optimisations that will deliver a LNG project which will have capacity to produce 27mtpa with just five LNG trains.According to the company, the optimisations are expected to result in several environmental and community benefits when compared with the original plan for six-train project.The benefits include about 21% of less CO2e emissions, reduced construction time for the full project, reduced facility footprint as well as reduction in traffic on roadways.NextDecade is planning to vacate Train 6NextDecade chairman and CEO Matt Schatzman said: “This is an extremely positive development for all of our stakeholders, as the environmental benefits from these optimizations are significant.“In addition to the emissions reductions we will achieve, these optimizations will reduce the project’s footprint, traffic, and construction schedule, and demonstrate our ongoing commitments to the community in the Rio Grande Valley.”Depending on the optimisation plans, NextDecade said that it will vacate Train 6 as the project is now capable of producing the same planned total LNG volumes with five trains.Estimated to cost more than £11.7bn ($15bn), the gas liquefaction and export facility will be located at the Port of Brownsville.In February this year, NextDecade signed an agreement with Canada-based energy infrastructure firm Enbridge to sell Rio Bravo Pipeline (RBPL) for a cash purchase price not to exceed $25m. NextDecade will optimise the LNG project which will have capacity to produce 27 mtpa with just five LNG trains instead of six trainslast_img read more

Wind Booms, Coal Suffers in Oversupplied Texas Grid

first_img FacebookTwitterLinkedInEmailPrint分享S&P Global Market Intelligence:When Vistra Energy Corp. subsidiary Luminant Generation Co. LLC announced on Oct. 13 that it would retire two large coal plants in Texas next year, the company stated that “these two plants are economically challenged in the competitive ERCOT market” because of “sustained low wholesale power prices, an oversupplied renewable generation market, and low natural gas prices, along with other factors.”That statement echoed what has become a truism among merchant generators operating in the Electric Reliability Council of Texas region: the rapid spread of cheap wind power is creating an oversupply of electricity in the Texas market. ERCOT oversees the grid that supplies most of Texas with its electricity.“ERCOT is currently oversupplied,” found a December 2016 report prepared for the Texas Clean Energy Coalition by the Brattle Group, Inc. that looked at grid reliability in the face of rising penetration of renewable energy sources and accelerating retirements of coal-fired plants, “and the forecasted additions of natural gas, solar, and wind generation should provide a cushion to absorb many of the retirements that may occur.”A market that appears oversupplied to an owner of coal-fired plants, however, may not appear so to a grid operator charged with maintaining adequate resources for summertime peak loads. What’s clear is that as the penetration levels of wind and solar generation climb toward and past the 20% threshold, the issues around supply and demand, grid stability and market functioning become more complex. And Texas, a pioneer in wind power, could serve as a glimpse into the future of the U.S. power grid as renewables become cheaper and more widespread.Even as peak loads have remained relatively flat in the region in the last few years, total operating capacity from all sources combined has continued to climb.And much of that new capacity comes from wind, which grew from just over 11,000 MW in 2013 to nearly 16,260 MW in 2016 — a 48% increase in just three years — despite a renewable energy mandate that was met years ago.Following a construction boom fueled by the federal tax credits and the state’s $8 billion investment in long-distance transmission lines, Texas has nearly 20,000 MW of wind power capacity. The state supplied 25% of U.S. wind power in 2016, and wind capacity in the state is expected to reach 25,500 MW by 2019. Along with abundant supplies of low-priced natural gas, all that wind has helped depress energy prices in Texas. Despite having, by far, the highest energy usage per capita in the nation, Texas enjoys energy prices per MWh among the lowest of any state.As the Luminant retirements indicated, low wholesale power prices are driving coal generators out of the market. Exacerbating that trend, the wind boom is expected to be followed by a solar boom in the Lone Star state; in its most recent long-term scenario, ERCOT said between 14,500 MW and 28,100 MW of solar capacity could be added to the system by 2031. Through September, Texas had generated about 17% of its electricity from wind in 2017. Developers have already signed interconnection agreements for another 8,655 MW of new wind, plus 2,050 MW of new solar installations, in ERCOT.For coal plant owners, low natural gas prices and high wind penetration “have been like a one-two punch,” says Chen-Hao Tsai, senior energy economist with the Jackson School of Geosciences at the University of Texas, Austin. “If solar really takes off as ERCOT predicts, that will replace a good amount of generation from conventional generators during the daytime. I would consider that the third punch.”Adding to the blows against coal, natural gas plant construction is proceeding as well: “more than 14 GW [of] gas-fired generation capacity are also in the pipeline, with 7.6 GW scheduled to come online in 2018,” according to a July 2017 report by Tsai and his colleague Gürcan Gülen for the International Association of Energy Economics.What goes for Texas today could soon apply to the U.S. as a whole. According to the American Wind Energy Association, nearly 26,000 MW of wind capacity is now in development nationwide, with more than 14,000 MW under construction. New installed wind capacity reached 2,357 MW in the first half of this year, the American Wind Energy Assocation says, pushing total installed capacity to 84,405 MW. According to the U.S. Energy Information Administration, electricity generation from wind will reach about 526 billion KWh by 2040, nearly 11% of total U.S. generation.The Department of Energy’s more ambitious Wind Vision program aims to boost wind to 35% of U.S. generation by 2050.In Texas, meanwhile, wind power’s position is being strengthened by new farms built not in West Texas, home to the majority of the capacity built to date, but along the Gulf Coast. While West Texas still accounts for the majority of the state’s wind capacity, wind power along the Gulf Coast has increased sixfold in the last five years, reaching 2,385 MW, or nearly 12% of the state’s total wind capacity. That’s important because Gulf winds blow more consistently than those in West Texas, and better match with the peak daytime hours for electricity consumption, overcoming the variability that of generation from farms in West Texas, where the wind is highest at night.That will likely crowd out more fossil fuel generation, especially from coal plants, which are less flexible than plants that burn natural gas and are thus less able to ramp up quickly when the sun’s not shining and the wind’s not blowing. According to a May 2016 report from the Brattle Group — also prepared for TCEC — coal generators face a sharp decline in Texas: Coal’s share of generation in the state will fall from 34% in 2013 to 6% in 2035.Coal’s dethronement in Texas has implications for coal producers in Wyoming’s Powder River Basin, as well. Texas, which consumed some 86 million tons of coal in 2015, much of it from Powder River mines, is by far the largest coal market in the U.S. Accelerating retirements in Texas will have a dramatic effect on Powder River Basin mines: Luminant’s Monticello and Big Brown plants, for instance, both of which are now slated for early retirement, bought up 54% of production from Peabody Energy’s Rawhide mine through the first seven months of 2017, according to the Institute for Energy Economics and Financial Analysis.More: Wind booms, coal suffers in oversupplied Texas grid Wind Booms, Coal Suffers in Oversupplied Texas Gridlast_img read more

Bill targets human trafficking

first_img Bill targets human trafficking Calls on the Bar to educate lawyers about modern slavery A bill toughening penalties for human trafficking has cleared a key committee in the Florida Senate.SB 250, sponsored by Sen. Gwen Margolis, D-Miami, passed the Criminal Justice Committee recently, winning praise from members. Among other provisions, the bill calls on The Florida Bar and the Florida Court Education Council to improve education programs for lawyers and judges to help them recognize the victims of modern slavery when they encounter them.“We want to educate our law enforcement and courts that there are people who are being trafficked,” Margolis said. “Some come in on a travel visa and then they disappear. Some are victims of being told they were going to come over and they would have a job and they would have a better life.”But once in this country, their exploiters take away their papers, keep them from communicating with their families in their home country, restrict their movements, control the money they earn, and typically force them into prostitution or domestic servitude, she said.“It’s really a training issue. The courts have to know what to look for and obviously law enforcement needs to know how to look at this,” Margolis said.The bill would also allow human traffickers to be prosecuted under RICO laws, she said.Sen. Fredericka Wilson, D-Miami, said she saw the same television news investigative series on human trafficking that prompted Margolis’ bill, adding she too planned to introduce a bill but Margolis acted first.“I think the part that really got to me was they said 50 to 60 percent of these victims were minors,” she said. “They [traffickers] were going to Brazil and places like that and selling a bill of goods to poor minors.”The committee unanimously passed the bill, which next goes to the Senate Judiciary Committee and the Justice Appropriations Committee. An identical bill, HB 469, has been introduced in the House and referred to four committees. February 15, 2006 Regular News Bill targets human traffickinglast_img read more

Pros and cons of remote work

first_imgRemote working is an ideal way to be sure you are hiring the best possible talent, recruiting talent from competitors, reducing relocation expenses, and minimizing the impact of a job change on an employee’s family. Mergers, acquisitions, merging up, or takeovers require the industry to rethink the office as the standard corporate meeting place.Work without Walls is a Microsoft white paper that states, “62 percent of employees believe their productivity increases when they work remotely . . .” Conversely, only 15 percent say their company’s support remote working.  There is a definite gap to discuss.Remote employees have many opportunities to increase productivity. These same employees worry that bosses lose confidence in the employee’s ability to effectively perform as a fully engaged employee if not physically present in the office space.Following are some pros and cons to remote working. Then I discuss one of the biggest challenges I have seen in the industry regarding the C-Suite and remote working. continue reading » 36SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblrlast_img read more

Dengue fever outbreaks may be more severe in future, says Bahamas study

first_imgHealthLifestyle Dengue fever outbreaks may be more severe in future, says Bahamas study by: – November 2, 2011 Share Share Share Sharing is caring!center_img Tweet 11 Views   no discussions Image via: topnews.inNASSAU, Bahamas — A proper research facility is needed to assist in the fight against dengue fever, which is becoming more prevalent in The Bahamas, according to a recent study, ‘Dengue Fever: An Emerging Infectious Disease in The Bahamas’, released in The International Journal of Bahamian Studies by The College of The Bahamas (COB) last week.The study’s lead researcher is Sherrie V. Bain, who is an adjunct microbiology instructor at the Keiser University in Florida. According to the study, several recorded cases of the acute form of dengue fever this year (dengue hemorrhagic fever) suggest a trend that dengue fever might return in future with increased severity.“This is not the first time that a dengue fever outbreak has occurred in The Bahamas,” notes the study. “Dengue fever outbreaks also occurred in 1998 and 2003. However, the number of confirmed cases in this year’s outbreak, as of October 2011, is almost seven times that of the last two dengue fever outbreaks combined. On a national level, The Bahamas will need a multi-faceted, preemptive approach that is not simply limited to vector control at the onset of the next outbreak.”The study also notes that the spread of dengue fever will not be curbed by addressing the mosquito population alone.“It is time for the public health sector, as well as The College of The Bahamas, to begin to take measures to develop a comprehensive dengue fever eradication policy in The Bahamas,” read the study. “Although reduction of the Aedes vector population by using insecticide may seem like the obvious route to pursue, it may also prove to be the most difficult goal to accomplish. Even when chemical insecticides are used, the impact on the mosquito population is not permanent.”The study also indicates that due to The Bahamas’ abundance of natural habitats such as mangrove swamps, the application of insecticides might prove ineffective in dengue virus control in the long term.“Having a low density of the mosquito population does not always correlate to having a lower incidence of the disease within a specific geographic location,” read the study. “Therefore, The Bahamas should look beyond simply trying to control the vector population as a lasting solution to eradicating dengue fever. These alternative strategies need to include researching how the disease is transmitted in the mosquito vector, as well as how it may be prevented from becoming established in its human hosts.”The study states that emphasis should to be placed on developing a national infectious disease research centre that will focus primarily on discovering drug and vaccine targets against diseases such as dengue fever.“This is an objective that will require the participation and partnership of multiple governmental and private organizations within The Bahamas,” notes the study. “The Public Health Authority and the Department of Environmental Health will have to share intellectual and material resources to successfully establish a national infectious research center in The Bahamas.”By Royston Jones JrNassau Guardian Staff Reporterlast_img read more

Cayetano not yet ‘off the hook’ on SEA Games fiasco

first_img Duterte added that his statement last Thursday that Cayetano, who chairs Philippine Southeast Asian Games Organizing Committee, is innocent of corruption was only his opinion. Contrary to his previous claim, Duterte said the investigation being done on the logistical troubles prior to the opening of the biennial sporting event will spare no one. “If it causes me and my allies to fall politically then so be it,” President Duterte said in an interview with CNN Philippines on Friday night.   “That is just my opinion, I could be wrong but I have known Cayetano for many years. I have always believed in him,” the Chief Executive said. However, Duterte said that the probe should proceed presuming everyone is innocent. “I think that the investigation should proceed with the presumption of innocence then along the way if you find some wrong – either negligence or intentional – let it out and sort out what to do next either to file charges or not,” he said.center_img MANILA – House of RepresentativesSpeaker Alan Peter Cayetano is not yet absolved from the controversies houndingthe 30th Southeast Asian (SEA) Games, said President Rodrigo Duterte. “I was just kind of shooting breeze with everyone.
