theHating: Proxy temperature stacks for 30° latitude bands with 1-sigma uncertainties. The stacks have been normalized by the glacial–interglacial (G–IG) range in each time series to facilitate comparison. Shakun et al. Figure 5b.
4 years ago • Report 0 theHating: As we already knew, the Earth's orbital cycles trigger the initial warming (starting approximately 19,000 years ago), which is first reflected at the highest latitudes (i.e. Greenland and the Arctic - see "Onset of seesaw" in Figure 4). theHating: This influx of fresh water then disrupted the Atlantic meridional overturning circulation (AMOC), in turn causing a seesawing of heat between the hemispheres. The Southern Hemisphere and its oceans warmed first, starting about 18,000 years ago. The warming Southern Ocean then released CO2 into the atmosphere starting around 17,500 years ago, which in turn caused the entire planet to warm via the increased greenhouse effect. theHating: "Lag correlations from 20–10 kyr ago suggest that the modelled global temperature lags CO2 concentration by 120 yr, which is within the uncertainty range of the proxy-based lag." {...} "Our global temperature stack and transient modelling point to CO2 as a key mechanism of global warming during the last deglaciation. Furthermore, our results support an interhemispheric seesawing of heat related to AMOC variability and suggest that these internal heat redistributions explain the lead of Antarctic temperature over CO2 while global temperature was in phase with or slightly lagged CO2." Sir Loin: As editor of the annual Meteorological research journal years ago I became fairly expert in translating bullshit in scientific reports but Hating you have me beat sometimes. Sir Loin: What's ya problem with Kiwis Beaver? Are you an Aussie pissed off because we thrashed you in the Bledisloe? theHating: Sir doesnt believe in calculating complex equations. He thinks some aspect of that isnt real. Hahahahaha Sir Loin: I don't believe in modelling data, then treating them as observed data to "prove" the model is correct |
