    Had an interesting conversation at the ice hockey rink locker room this morning. One of the team mates had recently gotten back from an overseas holiday, and his son had insisted that they offset the carbon footprint by eating vegetarian food for two months. Which they did.

    When you think about that carefully, itís easy to see that you can forget politicians and taxes. The change will come from other direction.

    And what’s their penance for an away game?

    It’s called planetary motion

    There’s an inevitability to cyclical Earth warming and cooling .

    We had three ice ages and in between three “ global warming’s “
    Last one the N pole ice cap came down to a line from Lyon to Vienna .
    When it retreated we got the Alps and the channel + loads old other U shaped valleys like the Ogwen in N Wales etc etc .
    This all happened before any effective man made attributing effects .
    So how come ?

    Well it’s to do with planetary alignment and gravity .

    Ideally all 9 planets ( or what ever number) orbit in a pure circle round the sun .
    So there yearly seasons are the same temp wise because there distance from the sun is constant .
    But in reality they gravitationally interact with each other .

    The bigger ones can pull slightly the smaller ones .We are a small one .
    So distort the circle to more egg shape .Hence our seasons .With 8 others spinning we have no chance of zero interaction and a pure circular orbit , and we haven’t got one .We have a distorted egg shape .

    But every 100 or 1000 years it’s possible that due to the alignment a few big ones can really distort the egg shape of the lighter ones like Earth .

    Fine you say .When the Earth moves to the end , the most egg part , the most distance from the sun ...Ok we have a cold winter so what ?
    Buy it happens gradually and the ice at the N pole when the Earth is at the nearest position high summer does not melt back to the baseline so as the decades pass the Earth cools and there’s a 5 mike thick ice sheet over 1/2 of the EU .
    The reverse happens when the gravitational influence of the largest diminishes, which is exactly what’s happening now , we - the orbit has been loosing its gravitational influence of the biggest planets .
    Further more if the gravitational influence is lower than average then the orbit becomes more proper circle as less egg then the Earth goes through ..... the “ seasons are all the same “ theses days .

    Global warming

    Has mans , could man environmentally have any influence on the Earth orbit changes , the position of the other planets .....NOPE

    So what we are seeing with 0,3 degree ( or what ever ? ) rise in Ave temps is due to a more circular orbit as opposes to a more egg shaped .

    Both extremes are not nice .
    I mean anyone up for a 4 th ice age .

    Don't we own boats to get away from society..so i don't think many will give a stuff about what others think of us?

    Seasons are nothing to do with Earth's orbit and everything to do with the Earth's axis of rotation. Suggest you read up a bit more on the subject.

    It would seem that he has.
    Also I believe known as the Milankovitch effect

    It’s the extremes gradual warming or cooling .
    How do you explain the disappearance of ice from Lyon to Vienna .
    We can only see Obviously the extent of the last ( of 3 may be more ? ) ice aged .

    Summers are getting hotter or winters warmer because we are orbiting closer to the heat source ......at the mo .

    Just read this , it seems the “ tilt” changing too ( has a variable range ) in favour of hotter summers for us at this lat .

    https://en.m.wikipedia.org/wiki/Milankovitch_cycles

    So I can’t really see packing up meat for 2/12 or down sizing your diesels is gonna really x compensate for the gravitational influence of Jupiter and Saturn .
    The fuel may well change and it’s usage pattern alter , but then it’s had anyhow say from 1960 ,s .It just evolved with the available tech .

    Getting a bit pedantic, but that is one of the many contributing factors (which includes atmospheric CO2, water vapour and other geophysical factors) believed responsible for glacial and interglacial periods. The fact seasons exist is due to the axis orientation (which is why they occur on an annual basis), with parts of the Milankovitich effects changing the severity of the seasons. Our incomplete knowledge is why some of the potentially devastating impacts of climate change are not fully understood - many positive and negative feedback mechanisms to consider.

    Getting back to the core of the thread, we sold our Cranchi Endurance in March with a view to giving up boating forever. Then a trip to the IOW set me off again - the pull of the sea etc. So, a few weeks ago, we bought another boat, this time a Bavaria 34 sailing boat. A beauty it is too. It will suit our pottering around the Solent, sometimes sailing, sometimes motoring. In latter form, it’s D1-30 uses around 2 litres an hour for 6 knots. Old and on fixed incomes these days, that will do nicely thanks.
