Younger Dryas Hypothesis - The whole picture

Hi to everyone! My name is Anatoly, from Russia. I think the most here heard at least one time about the Younger Dryas Hypothesis and the comet impact that happened 12,800 years ago! Some saw may be Graham Hancock and Randall Carlson talking about these events, while the academic science already tries to refute this hypothesis. Well, at least none argues about the existence of the Younger Dryas Boundary (YDB) that dates back to 12+ thousand years. So the facts are there that something big... Read more ..read more

Oxygenation Without Photosynthesis

I thought this was interesting: https://www.nature.com/articles/d41586-024-02393-7 It seems manganese nodules on the sea floor can somehow generate free oxygen! The mechanism has yet to be explained. If this is confirmed it could add another aspect to the story of how the Great Oxygenation Event took place. It has also potential implications for the environmental effect of mining these nodules ..read more

Environmental impact analysis: older vehicle v. new electric vehicle

exchemist said: To be fair, I am advised that it is greener to run an old vehicle into the ground than to replace it, due to the emissions involved in manufacture of new vehicles being so large compared to those from operation. On that basis I am continuing to run my 20r old petrol VW Golf as long as possible, before investing an electric vehicle, which is what I plan to do when it conks out. Cradle-to-grave analysis can yield results that are not immediately obvious. Click to expand... I've been curious about... Read more ..read more

Hurricane Beryl

Hurricane Beryl: Record-breaking sign of warming world Beryl is the earliest category five Atlantic hurricane on record, fuelled by exceptional sea warmth. www.bbc.co.uk Apparently the earliest category 5 hurricane in the season for a century, with a likelihood of more and stronger ones to come. This is the kind of thing predicted by climate change modelling. And yet we still have people like sculptor who pretend it’s all to do with the sunspot cycle, or else take refuge, ostrichlike, in cod-frontiersman stuff, expressed in suddenly demotic language, about their “yard”, planting trees and ..read more

Satellite data reveal electromagnetic anomalies up to 19 days before 2023 Turkey earthquake Earthquakes may betray their impending presence much earlier than previously thought through a variety of anomalies present in the ground, atmosphere and ionosphere that can be detected using satellites, a recent study in the Journal of Applied Geodesy suggests. phys.org Developing early warning systems for earthquakes could be very helpful in preventing death and destruction. One such proposed technique involves using satellites to monitor a variety of physical and chemical parameters within th ..read more

Writing from a home running mostly on solar electricity, at night too, that exports 2 to 3 times more electricity than it consumes. It isn't all the way there; no deep cold Winter here to deal with and we still use locally sourced wood for heating supplemented by some reverse cycle aircon (daytime use to pre-warm). Would need about 3X the batteries to switch over fully to reverse aircon (air source heat pump) heating and more solar would be good too. Right now solar leaves enough left over...

Earth's oldest fossil forest found is SW England

by Pinball1970
7M ago
In this paper we report evidence for a previously unrecognized cladoxylopsid forest landscape, archived within the Eifelian Hangman Sandstone Formation of Somerset and Devon, SW England. This unit has previously been considered palaeobotanically depauperate but is here shown to contain the earliest fossil evidence for such trees in the British record, as well as the oldest known evidence globally for the relative position of standing trees: Paper here....
