A 950 yr temperature reconstruction from Duckhole Lake, southern Tasmania, Australia

first_imgA lack of quantitative high resolution paleoclimate data from the Southern Hemisphere limits the ability to examine current trends within the context of long-term natural climate variability. This study presents a temperature reconstruction for southern Tasmania based on analyses of a sediment core from Duckhole Lake (43.365°S, 146.875°E). The relationship between non-destructive whole core scanning reflectance spectroscopy measurements in the visible spectrum (380–730 nm) and the instrumental temperature record (AD 1911–2000) was used to develop a calibration-in-time reflectance spectroscopy-based temperature model. Results showed that a trough in reflectance from 650 to 700 nm, which represents chlorophyll and its derivatives, was significantly correlated to annual mean temperature. A calibration model was developed (R = 0.56, p auto < 0.05, root mean squared error of prediction (RMSEP) = 0.21°C, five-year filtered data, calibration period 1911–2000) and applied down-core to reconstruct annual mean temperatures in southern Tasmania over the last c. 950 years. This indicated that temperatures were initially cool c. AD 1050, but steadily increased until the late AD 1100s. After a brief cool period in the AD 1200s, temperatures again increased. Temperatures steadily decreased during the AD 1600s and remained relatively stable until the start of the 20th century when they rapidly decreased, before increasing from AD 1960s onwards. Comparisons with high resolution temperature records from western Tasmania, New Zealand and South America revealed some similarities, but also highlighted differences in temperature variability across the mid-latitudes of the Southern Hemisphere. These are likely due to a combination of factors including the spatial variability in climate between and within regions, and differences between records that document seasonal (i.e. warm season/late summer) versus annual temperature variability. This highlights the need for further records from the mid-latitudes of the Southern Hemisphere in order to constrain past natural spatial and seasonal/annual temperature variability in the region, and to accurately identify and attribute changes to natural variability and/or anthropogenic activities.last_img read more

Google announces deals for 1.6GW of new wind and solar generation

first_imgGoogle announces deals for 1.6GW of new wind and solar generation FacebookTwitterLinkedInEmailPrint分享Greentech Media:Google announced a package of renewables deals on Thursday totaling 1,600 megawatts, which the tech behemoth says is the largest corporate renewables purchase in history.Made up of 18 deals, Google’s projects will be built across the U.S., Europe and in Chile. The company said the purchases will increase its total wind and solar agreements by more than 40 percent.Amazon joined Google in dropping a big commitment on Thursday, announcing plans to achieve 100 percent renewable energy by 2030 and net-zero carbon by 2040. In a statement, CEO Jeff Bezos said Amazon was “done being in the middle of the herd on this issue.”Even when companies lock in 100 percent renewables commitments, it can be tricky to quantify their environmental impact. A company’s demand for renewables doesn’t necessarily shut down fossil fuel plants and encourage building new wind or solar in their place.“We’re not buying power from existing wind and solar farms, but instead are making long-term purchase commitments that result in the development of new projects,” wrote CEO Sundar Pichai of Google’s 1,600-megawatt announcement in a note published Thursday. More than half of the new Google projects are solar, following on a trend of corporate renewables purchasers turning toward offsite solar as a low-cost option. Wood Mackenzie Power & Renewables forecasts solar will overtake wind in the mid-2020s as the go-to choice for offsite corporate renewables purchases. In the U.S., all of Google’s new projects will be solar, with 75 megawatts in South Carolina and 490 megawatts in Texas.More: ‘Largest ever’: Google announces 1.6GW of renewables purchaseslast_img read more

Old forage gets a new life

first_imgShare Facebook Twitter Google + LinkedIn Pinterest A forgotten forage grass imported from Europe in the 1800s could soon be helping to boost cattle and dairy production. The grass, which has adapted well to parts of the Upper Midwest, has been released by U.S. Department of Agriculture Agricultural Resarch Service scientists in Madison, Wisconsin.The forage grass was discovered on a farmer’s shaded hilltop in a long-time pasture that had never been seeded with commercial forages. Cattle thrived on it and it gradually spread from the hilltop grove into gullies and open areas, possibly because cattle eating the ripe seed spread it in their manure. The farmer fed hay made from it to more cattle, to spread it further. He also eventually began consulting with ARS plant geneticist Michael Casler and his colleagues at the U.S. Dairy Forage Research Center.Casler and his colleagues have since spent more than a decade evaluating the grass, named Hidden Valley for the farm where it was discovered. In field trials and other tests, they evaluated how cattle respond to it and how well it grows in a variety of locations. They found that it produces a 9% lower yield than orchardgrass and tall fescue, but has a 9% higher rate of neutral detergent fiber digestibility. That means cattle digest it more easily and eat more of it, in turn gaining more weight and producing more milk. Research also shows that it has adapted to the Upper Mississippi River Basin by developing several desirable traits. It is drought tolerant and will survive freezing temperatures and repeated grazing.DNA tests show it to be a meadow fescue brought to the United States by European settlers in the 1800s. By the 1950s, meadow fescues had largely been replaced with higher yielding tall fescues and other grasses. But they never completely disappeared as forages. A movement toward managed grazing operations in the 1980s prompted renewed interest in them, and ARS researchers and colleagues at the University of Wisconsin evaluated 91 varieties in extensive field trials, including seven European varieties, on three Wisconsin dairy farms. But Hidden Valley stands out, according to Casler.“What was originally found on this farm is really remarkable,” he said.Like other meadow fescues, it has an endophyte (symbiotic fungus) that gives it some degree of environmental protection. But it does not produce the compounds found in tall fescue that can sometimes harm cattle.Surveys of the Upper Midwest “Driftless Region,” which includes parts of Illinois, Iowa, and Minnesota, also show that it can be found in a wide range of habitats and seems to grow well on land taken out of crop production and allowed to revert to pasture.Casler released Hidden Valley in June 2014, publishing an announcement in the Journal of Plant Registrations, and seed is available through the National Plant Germplasm System.last_img read more

McGregor holds strong on prediction of a knockout

first_imgConor McGregor has his hands wrapped before a media workout Friday, Aug. 11, 2017, in Las Vegas. McGregor is scheduled to fight Floyd Mayweather Jr. in a boxing match Aug. 26 in Las Vegas. (AP Photo/John Locher)LAS VEGAS — Conor McGregor is convinced he will beat Floyd Mayweather on Aug. 26, inside of four rounds.And if the Nevada Athletic Commission approves the fighters’ request to use eight-ounce gloves, he said he will beat Mayweather in the first six minutes of the fight.ADVERTISEMENT Typhoon Kammuri accelerates, gains strength en route to PH LOOK: Venues for 2019 SEA Games READ: Mayweather promoter tired of talk about ticket salesWhile speculation is McGregor will be the aggressor early on, his gameplan and strategy remain a mystery since this will be his first professional boxing match. What hasn’t been a mystery is the air of confidence he displays, combined with a clear disdain for his opponent that has him assured he will hand Mayweather his first professional loss.“You can’t prepare for me, you can’t prepare for me, you can’t prepare for the movement, you can’t prepare for any of it,” McGregor said. “He can sit here and watch this (workout), and I’m sure he has been watching that. Let him watch, let him try and study, but you cannot prepare for this. There is nobody in the game that moves like me, that strikes like me and that has the confidence like me.“This is a fight that has been in my crosshairs since Floyd’s been opening his mouth, simple as that. I see a beaten man in his eyes, in his body language, in everything he does. I’m going to knock him out bad, he’s too small. I know he’s fast, I know he’s got good reflexes, I know he’s experienced. I don’t care. I hit you, you fall, and that’s it. He will be unconscious.” WATCH: Streetboys show off slick dance moves in Vhong Navarro’s wedding Catriona Gray spends Thanksgiving by preparing meals for people with illnesses UPLB exempted from SEA Games class suspension K-pop star Jung Joon-young convicted of gang rape, spycam crimes “He’ll be unconscious inside two rounds, really one round, only for the 10-second count I will give him maybe surviving into the second,” said McGregor, who enters the boxing world with a 21-3 MMA record. “But if it’s 10-ounce gloves, maybe four rounds.

Other times he looked like an MMA fighter eager to charge his opponent, something he obviously can’t do in a boxing match. Los Angeles takes another step toward 2028 Games But with as much hype and promotion being thrown into the ring with both fighters, McGregor left plenty of intrigue and insists he didn’t show half the boxing skills he honed has a youth in Ireland, simply teasing anyone in attendance and everyone else who may have tuned into any livestreaming on social media.READ: Mayweather-McGregor is a stale act already “I don’t know how many times I’ve shocked the world, and I’m going to shock it once again,” McGregor said. “It’s not going to end well for Floyd. It’s not going to end well for all the people doubting me.”The 29-year-old Irishman insists nothing has changed in his training, other than the fact he can’t use his legs or take his opponent to the ground, and he’s the same hard-working fighter that won two Ultimate Fighting Championship titles.“I show up to the gym, I work hard, and through my hard work I gain my confidence – that’s been the same since day one,” said McGregor, the reigning UFC Lightweight Champion and former UFC Featherweight Champion. “The fundamentals are still there, I show up, I work hard.”ADVERTISEMENT Brace for potentially devastating typhoon approaching PH – NDRRMC Read Next SEA Games in Calabarzon safe, secure – Solcom chief LATEST STORIES MOST READ Manny Pacquiao on Floyd Mayweather: Let him enjoy retirement PLAY LIST 00:44Manny Pacquiao on Floyd Mayweather: Let him enjoy retirement01:49Pacquiao to Mayweather: Want fans to stop asking for rematch?
