Malizia II – MartinHedberg.se

At 1500 GMT today (17:00 CET) Greta Thunberg, Boris Herrmann (skipper), Pierre Casiraghi (founder of Team Malizia), Svante Thunberg (Gretas father) and Nathan Grossman (filmmaker) will start their journey to sail from Plymouth to New York.

When you sail, the weather and ocean conditions are interesting, and very dynamic, conditions and boundaries. It is like a framework that sets the rules for your speed, comfort and safety. At the moment and in the future.

The weather changes all the time and as the ship moves it adds a dimension to the change. And it makes the forecasting very interesting. You don’t have to be a meteorologist or weather-geek to appreciate the conversations about how the atmosphere and ocean might, or might not, develop. At home or the office most people hardly notice small and large shifts in the weather. At sea it sets the rules.

Weather is not a mechanical system. No matter how much knowledge or powerful computer you have, you can never be certain about the development of the weather. But you can calculate the most probable development and different envelopes of evolution.

With these at hand, and knowing of how fast you can sail your yacht with different sails at different windspeed, and wind directions, you can calculate where you might be a couple of hours, or days, ahead. -But you have to take into consideration all the small steps in-between. This is called ”routing”, to navigate with respect to weather, waves and currents.

Different team have different goals when they sail. Is it to set a world record, to win a competition or to avoid storms, icebergs, waves and other harsh or dangerous conditions? If the goal was to gain speed you might consider heading north, to make use use of the intense low-pressure located between Ireland and Iceland now and over the weekend.

But the priority of this journey is 1.Safety, 2.Safety and 3.Safety. It will be hard and uncomfortable enough anyway for Greta, Svante and Nathan who has none (Greta) or only limited experience from off-shore sailing like this. The decisions from Boris Herrmann of how they will navigate will of course reflect this.

Someone compared the interior of the yacht to a tin can. It is a somewhat misleading metaphor. A tin can is nowhere near as optimised as this yacht. The tin can is for instance way too heavy in relation to its task and the environment it experiences. The boat is built for high speed sailing and you don’t add anything unless it brings speed or is necessary for safety. Paint for instance.

I was in contact with the team earlier today and they will take a somewhat southerly route. Not as far south so they reach the Trade winds, but just south of the Great circle between Plymouth and New York.

*Malizia II preliminary routing from Plymouth to New York. August 14, 2019.*

Right now, south of England, they will experience a 260/20(30) kts wind (i.e westerly wind, average speed 20 knots, gusts reaching 30 knots). It is close to head-wind so they will have to go SSW. North of Spain they will turn westward towards the Azores.

In meteorology the Azores are forever connected to sun and calm weather via the name ”The Azores High”, the North-Atlantic subtropical anticyclone. Right now there is a High centered over the Azores. But as Malizia II gets closer this weekend this has changed to low-pressure, a cold front and rain.

If it ain’t climate it is weather. Or ”Climate is what you expect, weather is what you get”. Now if you try to imagine unprecedented fast and very large climate changes. What kind of weather will we get in the future? Oh, btw, the future is already here. And the change accelerate.

Today you will set sail to cross the Atlantic. From Plymouth, England to New York, USA. When you last year started talking about sailing to the UN meeting in USA, you primarily viewed it as a sustainable transport. To do what most other people would have done, arguing that you had an important mission and therefore was justified going by airplane, was never an option for you.

You investigated going with a transport vessel or even to take the eastern way around the globe. For some time the option was the southern route over the Atlantic along with the trade winds. But it is long and this time of the year also include the risk of dealing with hurricanes.

You ended up choosing the northern Atlantic route. It is the shortest distance, not too warm and humid. Well, that is apart from all the moist and water the prevailing westerlies and extratropical cyclones, i.e. low-pressures, cold-fronts and mid-latitude storms, create in interaction with the ocean.

The crux with the northern Atlantic route, going from Europe to America, is that for lion’s share of time you will deal with variations of head-wind due to prevailing westerlies. The northern route is perfect going west to east. But as long as you don’t get stuck in a high-pressure, you will manoeuvre your sailboat to go in whatever direction you want.

There will be many reasons why the sail trip will make a lasting impression on you. Whatever vehicle you have travelled with before, to sail across an ocean is something extra. The first time you sail off-shore, watch the sun rise and set beyond the 360 degree ocean-horizon, experience a cloud-free night where the atmosphere is not polluted be either aerosols or light from surrounding cities, watch millions of stars in the Milky Way, small and large creatures living in the ocean, ride through a storm, pondering all the thoughts and conversations there are time for on board your ship, not to mention when you spot birds and land for the first time after a many days at sea.

The ship itself on the ocean is like a miniature of a society. Whatever tools, knowledge and skills you bring, is what you will have to do with. Of course you can catch some fish, collect rainwater and today also connect knowledge via satellite-communication. But you still have to handle whatever happens with whatever you have brought.

Things break, people get sick and there will be conflicts even over small matters. But on the boat there is no escape. One has to deal with everything. And that in itself is pretty beautiful and illustrative.

In ”the modern” life in cities many people don’t see the connections and relations between people and people, and nature we all depend upon. Neither do many people realize how changes in climate and ecosystems far away from them will impose changes to their life, today and in the future. But on a sailboat it is obvious, because everything is short distance and connected. There is a reason for the proverb ”to be in the same boat”.

The earth is round and there is no risk of falling over any edge when sailing towards the horizon, no matter how far one goes. But using geometry as a metaphor, there are slippery slopes and the world is about to accelerate along one or more of those. Science communicated this decades ago -and had societies acted promptly then, for example around the time for the first report from IPCC 1990, or why not in the 70’s when Limits to Growth was published and we had the first large oil-crisis?, we wouldn’t be in the climate crisis we are in today.

Today we make fun of people who claimed (some still claim!) the earth is flat. In the future people will blame and sue those who today are in the business of actively denying and counteracting the scientific knowledge about anthropogenic climate change and other man-made global changes, threatening resilient ecosystems and societies.

But many people understand the science and are concerned. However a lot think that their capacity to make a significant impact and change the devastating trajectory is too small. But then someone thought and said ”no one is too small to make a difference” 😉 Thank you.

Science is clear. Momentum among people grow. Humanity need to transform, or we will loose biodiversity, resilience, species and infrastructure beyond the carrying capacity of ecosystems and our societies. Systems collapse all the time, but we drive unprecedented changes and intensified collapses. It will force us, and all other life on the planet, into very uncomfortable adaptation. Individuals, eventually societies, suffer and die. Therefore, failure to mitigate the driving forces promptly, is not an option.

Every year of inaction, i.e. business as usual and continued emissions of greenhouse gases, we loose two years. The year of inaction and a year on the other side of the carbon budget. Every year of inaction we make the necessary transformation harder as the rate of change has to increase in order for us to stay within the budget.

Greta, you will have a very interesting, intensive and important year in America. But before that, starting this afternoon, take the opportunity to enjoy your journey with Malizia II, the crew and the ocean as you read the sky and manoeuvre your ship with a deepening understanding and relation to nature.

With kind regards,
