There is a strong school of thought that ocean temps derive from undersea volcanic activity. That makes sense to me, as nothing else I know of could change ocean temps on such a time scale. And we know that undersea volcanism is huge and variable. But if I say so I am rubbished and accused of being a denier. I can only conclude that climate alarmism is a religion, not subject to scientific analysis. I suppose the US government climate agency is woke.. https://www.climate.gov/news-features/understanding-climate/climate-change-ocean-heat-content Now, where is the eyes roll emoticon?

When I mentioned volcanic activity, I was thinking of above-ground eruptions. Didn't remember that plate tectonics is driven by the undersea volcanic activity that spreads the sea floor. 1 Link to comment Share on other sites More sharing options...
pmccarthy Posted January 21 Share Posted January 21 There are hundreds of undersea volcanoes, erupting all the time. It is how the heat from the earth's mantle is transferred up into the oceans. 1 Link to comment Share on other sites More sharing options...

pmccarthy Posted January 21 Share Posted January 21 (edited) Wikipedia says only 119 submarine volcanos erupted in last 11,700 years but I have seen maps with a lot more active ones so will look further. Looks like the difference is whether the volcano is venting or erupting. Edited January 21 by pmccarthy 2 Link to comment Share on other sites More sharing options...
nomadpete Posted January 21 Share Posted January 21 I imagine that it would be difficult to measure the heat added to oceans by volcanoes. But I expect volcanologists would know a lot about that. 1 Link to comment Share on other sites More sharing options...
old man emu Posted January 21 Share Posted January 21 2 hours ago, pmccarthy said: Looks like the difference is whether the volcano is venting or erupting. In either case, a "vent" as a noun is the break in the Earth's crust through which lava rises to the surface. "to vent" as the verb means to come out of a vent. Lava can either ooze out, or if the vent gets blocked, the lava can explode out in what we call an eruption. So the count of 119 undersea eruptions is probably a good accounting, however, there are lots more active volcanic vents where lava is simply oozing out. Venting tends to construct landforms, while eruptions destroy landforms. It is venting which moves the tectonic plates. The Hawaiian islands mostly have areas of venting, while the Indonesian islands and the Philippines have eruptions. 2 Link to comment Share on other sites More sharing options...
onetrack Posted January 21 Share Posted January 21 (edited) Now the climatologists are only just starting to include vast swathes of major bushfires in their calculations. But it's not like bushfires have only just started happening, we had one of the worlds biggest bushfires in 1939 and bad ones in the 1960's and 1980's. So the climate researchers are now saying, "Yes, the bushfires are affecting our climate - but we've only just started measuring it and adding the effect". WTF? Up until now, the climate researchers have been telling us their measurements are accurate, complete, comprehensive, and there's no possibility of error in the figures. Now, we find the researchers have forgotten something else in the equation - and every couple of years, they figure out something else needs to be added to the climate equation. https://www.abc.net.au/news/2024-01-22/are-megafires-contributing-to-climate-change/103219876 Edited January 21 by onetrack Link to comment Share on other sites More sharing options...

It's a spiralling cycle. As the climate warms and average temperatures increase in some areas, the fuel load will dry out more and thus fires will increase in size and intensity - which then impacts the climate. 1 2 Link to comment Share on other sites More sharing options...
old man emu Posted January 22 Share Posted January 22 Trends, trends, trends. They are the only Truth. The argument is: Is our knowledge of these trends based on long enough time? The length of time can only realistically be set by the use of ice cores, sediment cores and tree-ring analysis as first steps. However, suitable data from various "sediments" might only take us back 150 to 200,000 years. That is a mere "tick tock" of the geological timepiece. 1 Link to comment Share on other sites More sharing options...

old man emu Posted January 22 Share Posted January 22 Mother Nature seems to be hell bent on environmental suicide. From: https://www.theguardian.com/world/2023/sep/22/canada-wildfires-forests-carbon-emissions Emissions from Canada’s record-breaking wildfire season are probably triple the country’s annual carbon footprint, experts warn, as climate systems reach a “tipping point”. This summer, as flames devoured one of the largest contiguous stretches of woodland on the planet, 2bn tonnes (2.2bn tons) of carbon dioxide were released into the atmosphere. The figure far exceeds all of the emissions tied to Canada’s economy each year, which emit a total of 670m tonnes. But I have a way that we can each do our bit to reducing our share carbon dioxide going rapidly into the atmosphere - don't get cremated. Sequester your carbon in the ground by being buried. In fact, I think I'll start an environmentally friendly organisation whose aim it is to have all cremations banned.

facthunter Posted January 22 Share Posted January 22 Human behaviour (anthropogenic) does affect the CO2 in the air and that is easily measured accurately. CO2 in water produces 2 acids Carbolic and carbonic but while they are mild they affect crustaceans and plankton shells. A lot of the CO2 has been absorbed by the oceans but it can't go on doing it. When Permafrost melts the organic matter in it will rot and put a lot of CO2 in the atmosphere. Methane has a similar effect but not as long lasting. Sorry folks this one is delayed as I didn't post it at the time it seems. Here Goes. Nev 1 Link to comment Share on other sites More sharing options...

old man emu Posted January 23 Share Posted January 23 5 minutes ago, spacesailor said: HOW Did that " organic material " get to be ' under ' that permafrost, During the last Ice Age sequence, which occupied something like 200,000 years, there were warm periods during which that countryside was at least grasslands, similar to the grasslands of the plains of North America and East Asian steppes. Each season, when the grass died, it accumulated on the surface and plant material decomposed forming carbon-rich soils. Then the climate changed to freezing and the ground containing the plant material froze, becoming what we call permafrost. Now, as the permafrost begins to melt, that plant material i available for decomposition, which released carbon dioxide into the atmosphere. 1 Link to comment Share on other sites More sharing options...
