Sequence of events from the onset to the demise of the Last Interglacial: evaluating strengths and limitations of chronologies used in climatic archives

first_imgThe Last Interglacial (LIG) represents an invaluable case study to investigate the response of components of the Earth system to global warming. However, the scarcity of absolute age constraints in most archives leads to extensive use of various stratigraphic alignments to different reference chronologies. This feature sets limitations to the accuracy of the stratigraphic assignment of the climatic sequence of events across the globe during the LIG. Here, we review the strengths and limitations of the methods that are commonly used to date or develop chronologies in various climatic archives for the time span (∼140–100 ka) encompassing the penultimate deglaciation, the LIG and the glacial inception. Climatic hypotheses underlying record alignment strategies and the interpretation of tracers are explicitly described. Quantitative estimates of the associated absolute and relative age uncertainties are provided. Recommendations are subsequently formulated on how best to define absolute and relative chronologies. Future climato-stratigraphic alignments should provide (1) a clear statement of climate hypotheses involved, (2) a detailed understanding of environmental parameters controlling selected tracers and (3) a careful evaluation of the synchronicity of aligned paleoclimatic records. We underscore the need to (1) systematically report quantitative estimates of relative and absolute age uncertainties, (2) assess the coherence of chronologies when comparing different records, and (3) integrate these uncertainties in paleoclimatic interpretations and comparisons with climate simulations. Finally, we provide a sequence of major climatic events with associated age uncertainties for the period 140–105 ka, which should serve as a new benchmark to disentangle mechanisms of the Earth system’s response to orbital forcing and evaluate transient climate simulations.last_img read more

Binghamton man arrested, charged with arson

first_imgAuthorities reported a trooper noticed Hartman in the area of the fire with black soot on his forehead. Additionally, police said neighbors told troopers they saw Hartman “running” through a backyard not far from the garage fire. Police said on Aug. 9, troopers and the Nanticoke Fire Department were called to a report of a garage fire on State Route 26. State police say the investigation revealed Hartman broke into the residence to steal items and then set fire to the garage. New York State Police charged 24-year-old Alexander D. Hartman of Binghamton with arson and burglary in the 3rd degree.center_img TOWN OF NANTICOKE, N.Y. (WBNG) — Police arrested a man for starting a fire in a garage in the town of Nanticoke on Aug. 9.

Accused Donachie quits Magpies

first_img Press Association “They are passionate, they love the club and the best thing I can try to do is get the best team I can out there to get results for them. “I have no problem with that passion. It comes to the surface. There was a bit of frustration this week with season tickets going forward. “But two years ago, we finished fifth; this year, we are eighth and we have done a brilliant job. “We have lost a great player, we know that, and in the summer hopefully we can bring three or four great players in. Let’s hope so because this club deserves it.” Pardew insisted he was “sad” at Kinnear’s demise – a feeling which was not shared by many on Tyneside – after his reign came to an end a little more than seven months after he was appointed. He left having made only two loan signings in as many transfer windows and with many still wondering what his role was meant to be. The 67-year-old did not carry out any media duties after launching a series of initial salvos – the first came before his appointment had even been officially confirmed – and with Ashley happy to take a back seat, Pardew has found himself having to shoulder that responsibility. The role proved particularly uncomfortable in the wake of the Sunderland game when he was left to field questions about the Cabaye saga, many of which he could not answer. Pardew said: “Well, to be honest, I have probably been in that position for a long time. I have to carry that responsibility, and I have no problem with that. “I don’t want to talk about other things other than football, if I am honest, but sometimes you do and I give the best answers that I can.” It remains to be seen whether or not Ashley decides to persist with a director of football, but, if he does, Pardew insists he would have no problem with that. He said: “That decision is the board’s, but I have no problem with directors of football. In the modern game, a lot of clubs have directors of football. “There is so much involved in transfers in terms of the other club, agents, the preparation for the bid and the finances that are involved now that it goes way past what we used to do 10 years ago.” Newcastle will travel to Chelsea without key midfielder Cheick Tiote, who has been ruled out of the next two games at least by a hamstring injury and joins Fabricio Coloccini, Yoan Gouffran and Papiss Cisse on the sidelines, and the suspended Loic Remy. Newcastle reserve-team manager Willie Donachie has resigned on the day the club launched an investigation into an allegation that he hit one of his players. The Magpies confirmed on Thursday night that the 62-year-old former Scotland international had stepped down from his position. A club statement said: “Newcastle United can confirm that Willie Donachie has resigned from his position as reserve team manager with immediate effect. The club will be making no further comment.” The allegation surrounds an incident involving Donachie and 19-year-old defender Remie Streete after Monday night’s 2-0 Under-21s defeat at Sunderland. News of the former Manchester City player’s exit came as senior team manager Alan Pardew prepared to sit down with owner Mike Ashley to plot the way forward. The 52-year-old will send his depleted team into Barclays Premier League battle at Chelsea on Saturday after another tumultuous week on Tyneside. The Magpies rarely do things by halves, but, even by their standards, they excelled themselves by selling the best player, Yohan Cabaye, without replacing him, losing 3-0 at home to the Black Cats and then witnessing the departure of controversial director of football Joe Kinnear inside six turbulent days. The transfer window debacle and the derby defeat proved simply too much to take for some fans, one of whom ran onto the pitch to confront Pardew, while others have signalled their intention not to renew season tickets. However, asked what his message will be when he meets Ashley to discuss life after Kinnear, the manager said: “My message is always the same – it’s about taking the club forward. “We can’t stand still. We have to go forward, so it gives us an opportunity to do that. “Let’s be honest – it was an emotional game and the fan running on the pitch with a season ticket and all that, that’s what our fans are and they will never take that away from them. last_img read more
