It is known that glaciers on the Alps rapidly spread downwards as a result of contemporary written records, during the 16th and 17th centuries AD. At https://www.sciencealert.com/mysterious-artifacts-emerge-from-melting-ice-on-alps-glaciers … which begins by saying in 2022 and 2023 Switzerland lost ten per cent of its total glacier volume, presumably a reference to a global warming trope. However, to what degree the authors embraced the alarmist agenda is unclear as they go on to emphasize that in the Iron Age and Middle Ages people were travelling across the Alps with cows, mules, oil, wine, skiis, weapons and various other artifacts they left behind, subsequently picked up by hikers and archaeologists. No mention of elephant dung from Hannibal’s war elephants – but that may have been at a lower altitude. It has been estimated the glaciers shrank considerably in the Iron Age [including the Roman era]. The same was true of the medieval period. Basically, the thrust of the article is that melting ice is revealing objects left behind by people prior to the last advance of the glaciers – in the Little Ice Age. This is nothing for alarmists to gloat about of course as it simply proves the climate has been warmer in the past than it is now. All this is well illustrated in HH Lamb’s books on climate. Nowadays he is ignored by climate scientists – even though he was the founding scientist of the discipline, in the UK, and wrote an enormous amount of material on climate in Britain and in many parts of the world, including the Arctic.
Over at https://wattsupwiththat.com/2024/07/09/a-tale-of-2-opposing-ocean-warming-narratives/ … there are two differing narratives to explain recent observed ocean warming. One suggests that recent ocean warming is all down to human emissions that amplified the greenhouse effect. It is then correlated with rising co2 levels.
The second narrative suggests it was the 2023 El Nino southern oscillation [eENSO] combined with solar heating that has warmed the oceans. A quite different use of climate data. In fact, the author of the piece goes on to say the second narrative is supported by data as illustrated in NOAAs graphic of the ocean heat flux. NOAA of course is usually associated with the first narrative although very often they remain neutral. It was a clever idea to contradict the co2 agenda by making use of NOAAs own graphic. At this pont the author takes us through his assessment of the graphic and provides the reader with an image of said graphic. It shows the heat flux affected the eastern tropical Pacific and the Indian and Atlantic oceans. Other regions show no heat flux – or that is the point he is trying to convey. Whenever there is a greater flux of heat into the oceans that ventillates out, the oceans will warm, he says. Greenhouse infra red heating only penetrates a few microns into the skin surface of the oceans – and can be quickly be radiated back into space. Ocean warming by greenhouse gases is relatively insignificant. In contrast, solar heat penetrates the subsurface of the oceans – and recently there has been a lot of solar activity as we are in the middle of the current solar cycle. Indeed, the solar flare in mid May injected a lot of energy into the earth system and that energy had to go somewhere. We are enjoying benefits of that right now with above average warm temperatures in many parts of the world. Even in Death Valley according to the BBC. In Blighty it is somewhat different – distinctly cool for the time of year and lots of rain. Even the bees are shy this year. Yet, according to the mainstream mantra, the sun plays no role in recent warming. It is all down to co2. No doubt the jet stream plays a role in Britain’s wet weather and it is known that in the subtropics where the El Nino rears itself out of the depths of the Pacific, the trade winds play a role with the Intertropical Convergence Zone to bring rain. The last couple of years this has been enhanced by increased evaporation levels as a result of solar heating. Surplus solar heat, however, is absorbed by the ocean current conveyor belt [which is where the ENSO comes in] and moves through the Indian and Atlantic oceans and reaches the Arctic. At this point the warm water comes up against the cold water of the Arctic Ocean and rises to the surface. It is then ventillated into the atmosphere – and eventually into space, whence it came.
Anyone who can remember David Bellamy who was a one time popular television maker on biology and plant life in the 1970s and 1980s, may wonder why he suddenly became an unwelcome BBC personality. Go to https://www.express.co.uk/expressyourself/69623/BBC-shunned-me-for-denying-climate-change … and he did of course emigrate to the Antipodes in the aftermath. A salutory lesson in our Brave New World.
