Climate change

At https://phys.org/print404556950.html … Dansgaard-Oeschger events are sudden and dramatic episodes of warming that litter the last Ice Age period. They are thought to be associated with natural instabilities, or tipping points in climate change rhetoric. This is mostly because any other explanation seems to be less likely.

It involves the 'earth-system' – ocean and atmospheric circulation. In other words, changes in the earth system are triggered by a mechanism that is not understood. That the changes occurred is apparent – but not what caused them. Therefore there is a theory – and as the ocean circulation system is a convenient explanation from an introspective earth-centric point of view, that is what we have. What might cause the circulation system to switch is the big question – not that it happens. Well, that is not true of course as the co2 alarmism kicks in here and it is said to provide the boot up the backside of the ocean circulation system by an enriched atmosphere (but no industry in the Ice Age and no fossil fuels so this is a bit of a dilemma – but that doesn't stop the tie-in becoming a fact). 

A modelling project at https://cordis.europa.en/project/rcn/108394 … is seeking to investigate these inexplicable events by looking at, among other things, levels of co2. The idea is to find out if they can find a link in order to ratchet up the scaremongering. Obviously, if they can show co2 levels went up dramatically prior to the Dansgaard-Oeschger events they would add ammunition to their arsenal. We may note that it is essentially another modelling exercise that only factors in the info they think is relevant and this will heavily favour the desired outcome. At the same time it does make sense as the input of too much data, especially less well known data, by inference, would make the models unwieldy. It illustrates how limited models can be and why most people do not understand the faith put in climate models by the scientists. Hence, we have an exercise that excludes factors outside the earth itself – such as the role of the sun or the solar wind, passing cosmic bodies, or even the passage of the solar system through different regions of space (and it's position and transit as part of our galaxy). 

Over at http://advances.sciencemag.org/content/3/1/e1600815?utm_   we have an abstract of an article in Science Advances 3:1 (4th Jan 2017) – 'The tropical lapse rate steepened during the Last Glacial Maximum' – which shows that in the tropics air temperatures at elevation differed to what they are today. This is what one might expect if there was a small pole shift at the end of the Glacial Maximum, a realignment of the position of the equator. However, as pole shift is not at the table in mainstream thinking the argument instead involves temperature lapse rates. We may note lapse rates are one of the tools climate science uses in its calculations of projected climate change. Quite unaware of the hubris that comes across we are told 'state of the art' models are involved and this latest finding accelerates the rate of global warming (or whatever is the current in-word). Obviously, the End is Nigh.
