Re: La Vagabonde's crossing

I just watched a 1 hour and 17 minute video on Youtube about magnetic pole shift and a 12,000 year cycle of the sun going mini nova.
There was a lot of evidence to support it, like glass balls all over the moon and glassification in the Sahara Desert near the pyramids.

It could explain a lot about what people perceive as climate change etc.

I'm no scientist but it seems obvious to me that the cold melt water will flow over top of the warm saline water. Therefore, a cold region where the melt water meets the Gulf Stream.

That's right YouTube is a more reliable source than the IPCC. It looks like humanity is heading back to the stone age.

Re: La Vagabonde's crossing

What a great learning opportunity it’s been. The people who want it probably already have it, but fyi Predict Wind has 50% off at the moment (I’m thinking because of the heavy traffic) which was ideal as we had been hesitant to get the full package.

I can attest that what GT and the LV crew is doing has far reaching impacts beyond their own carbon footprint. For example, we have been sailing for years and own a sailboat. We live in a remote location where I have been commuting to the city by ferry and car. When I heard about Greta’s first Atlantic Crossing, I was struck that I had not entertained the idea of commuting to school by sailboat instead. So, that ’s exactly what I will be doing. This is a significant CO2 emissions reduction, and can be directly linked to her political and normative actions of choosing to sail instead of fly.

In less than 2 months, I alone will have reduced over 1 ton of CO2 emissions- about the amount of carbon emitted for ONE person traveling one way from the US to Europe by plane. This alone makes their voyage carbon neutral because my carbon footprint can be directly attributed to Greta’s choice to sail instead of fly! Any additional CO2 expenditures made for provision for the voyage will more than be offset by further inspiration created by the voyage alone. And the bigger picture is how corporations and governments respond to the public pressure created by people inspired by her message. We still live in a fossil fuel dependant infrastructure in which nobody can be 'perfect'; what’s important here is that the concept is being challenged, and is inspiring change.

Greta, Nikki and the LV crew are also inspiring more people to get into sailing. The means a stronger industry for all those who work in it. It seems like such a great way to carry on this maritime legacy. I think it’s an exciting time for sailing and a pivotal time for humanity.

Re: La Vagabonde's crossing

And huge thanks to breaking waves (single handed as well!) et al for posting all the routing stuff, very educational and interesting. Just managed to keep the thread about the weather til the end. Big thanx!

Re: La Vagabonde's crossing

I have followed this thread with great interest. I participated in an other thread with some comments on the climate change debate. That thread was closed. But after working more than 40 years in the fields of energy conservation and environmental protection I can't keep quiet any longer. The crew on LV had done an impressive crossing and the discussions on routing is interesting. But after sailing 50 years on the Baltic I have not much to say about routing, but I can say a few words on CC.

The level of some of the contributions concerning CC is far below the water surface. And the Greta bashing concerning flights of the crew is really of the point. Greta is only saying that politicians should listen to climate science and act accordingly. She has her own, strict morale and acts according to that and try to keep her carbon footprint as low as possible. But neither she nor anyone else believes that individual life style changes is enough to stop CC. What is needed is a phase out of all fossil fuel use and major change of our life styles. That means major political changes and also a change in our economic systems. I am afraid that his will not happen in the coming decades and therefore be too late to stop a major change in climate. This will not be the end of life, but parts of the earth will become unsuited for humans, and the stress on our social systems will be great.

It is interesting to try to analyse the force of the climate denial movement. It has not always been like this. When the scientific community accepted CC as a proven fact some 30-40 years even many conservative politicians like Merkel and Bush accepted the message from science and asked for actions. But after 30 years of lobbying from the industry with help from idiots on FB and YT we have a different climate (pun intended) where this topic is highly polarised. It is a bitter irony that when empirical fact of CC is to be seen everywhere the deniers are getting more vociferous and the level of the debate is sinking as the sea levels are rising.

Noon, first let me say I love the way you position the inspiration piece. Whichever side of the debate you are on, I cannot imagine what positive actions people expect to see by denigrating the actions of anyone promoting sailing or sailing as a way to promote more positive thinking about our role in climate change.
Can you elaborate on the metrics/numbers you used to calculate your reduction in carbon emissions and how you calculated it?

PUBLICITY..
Are you implying that is wrong ,,yes more publicity for a very important cause , what is wrong with that , maybe a bit more business for anyone involved , what is wring with that , a big welcome for the completion of an important voyage , what is wrong with that ????that is common place , remember Niome James return into Dartmouth , Che Blythe , Chichester , this years GG etc , why not Vagy ????

There has been a lot of pent up forum energy and the 500 mb charts had long been forecasting a bit of a political posting explosion as the voyage ended so, I fully expected this. I was just grateful that by and large it did not derail the thread during the voyage.

I'm biting my tongue with regard to the climate change discussion, but I'll gladly drift the thread in a different direction:


It kind of blew my mind that these folks were able to get across W to E and in this season without going through a single real gale. That is simply incredible to me. Everyone else I know who has done this passage has gotten whacked over and over again and even had to lie to a drogue once or twice. Even in season. Albeit at a higher latitude (to Ireland), and without this quality of routing. So here's a question for BW:


Is this the result of modern weather routing plus a reasonably fast boat?


If so, then that really changes a lot of things. It means that a fast catamaran could be used for a much wider range of cruising than I imagined. I was looking hard at an Atlantic 57 cat and I might look again. I wouldn't take such a vessel to the Arctic but for everything else this could really be the right thing, if it is really true that with speed plus this kind of intense weather routing we can even zip across the N. Atlantic from W to E out of season like this.


The idea of crossing oceans fast and with this kind of intense awareness of how the weather develops is very appealing. When we did the Arctic last year we did have someone helping from shore, but the routing was much less strategic than this and we did get whacked a couple of times, moderately. We just bash through -- that's why I sail a strong monohull. But I see there may be another way to do this, and it's intriguing.

Re: La Vagabonde's crossing

At 09:57 GMT Monday 2 December our friends were heading SE, straight towards continental Europe's westernmost point, Cabo da Roca - with a boat speed of 8.9 knots.
Distance to go to Cascais was 168 nautical miles - from where they will start their "glory lap" tomorrow morning - up the Tagus River, under the 25 de Abril Bridge (Golden Gate "sister bridge"), towards Lisbon City center.

Nikki Henderson's latest Facebook update gives an insight into their ordeals during the rather fresh sea and wind conditions the past days. One of which is running out of tea...

It's assuring to learn that Nikki and Riley are still vigilant and focused on the tasks of completing the voyage safely

Quote:
Day 20

After a day sailing east, we reaped the rewards at midnight and turned to starboard onto a course (145°) straight for Lisbon.

The previous 12 hours had been painful. As forecast, around lunchtime the wind shifted east of north so we started smashing upwind - gaining headway east. I think I actually gained air in my bunk a number of times during my afternoon nap! Lenny and Elayna relocated to the saloon as they couldn’t sleep down low - it was all a bit chaotic! We reefed down heavily at dusk, and thankfully so. It’s been blowing 30-40 knots all night, and it’s still going!

But at midnight it all became worth it for we gained about 15 degrees wider wind angle (this generally improves comfort, safety and speed) and the boat smoothed out. We can now say “only a day left”!

That’s both sad and exciting. But the sense of achievement will start to seep in - there is nothing quite like arriving somewhere and looking behind you and going “woah 3000 miles that way is America and we worked for every mile!”

Life yesterday - well it’s the 1st December so Svante and Greta kept in the Christmas theme with cinnamon oatmeal (porridge). We listened to a lot of Florence and the Machine whilst Elayna and I reminisced fun times at festivals. We have almost finished all our fresh food - so excellent provisioning Elayna. Actually some credit due - we all said we have honestly not wanted for anything - it’s been amazing (apart from when the tea ran out...!)

It can be hard as you approach a destination after so long at sea. Things are probably a little tense onboard. Just the anticipation of getting there really. The knowledge that we nearly can have a little space and privacy makes the boat feel a little smaller. The reality of ‘real life’ stuff like emails and bills and so on looms on the horizon. Land life starts to integrate with sea life. For Riley and I it means we have to be extra vigilant not to make mistakes or get too caught up in getting there. Just keep doing what we have done - safely, calmly - not let emotions drive any decisions - and we will arrive when we arrive. But yes - we are excited - very!!

Do they even understand their own BS?
They can't.
Global warming has been happening off and on for as long as the Earth has existed.
This is not an opinion, nor politics, its frickin' science!



The European Project for Ice Coring in Antarctica (EPICA) first drilled a core near Dome-C at 75°S 123°E 300 miles from Vostok.
The ice thickness there is 3,309m, the core was drilled to 3,190 m. It is the longest ice core in the world, where ice has been sampled to an age of 800,000 year's ago. Annual average temperature there is -54°C. Information about the core was first published in Nature magazine on June 10, 2004. The core revealed 8 previous glacial cycles. The warming and cooling cycles have a 100,000 year period. Homo sapiens evolved just 200,000 year's ago, leaving the culprit for the previous 7 warming periods still on the loose!
