“The term temperature anomaly means a departure from a reference value or long-term average. A positive anomaly indicates that the observed temperature was warmer than the reference value, while a negative anomaly indicates that the observed temperature was cooler than the reference value.”
“The southern African region is projected to be a climate change hotspot in terms of both hot extremes (Figures 3.5 and 3.6) and drying (Figure 3.12). Indeed, temperatures have been rising in the subtropical regions of southern Africa at approximately twice the global rate over the last five decades (Engelbrecht et al., 2015).”

“Reflections from the North Atlantic:
For what feels like the first time in the entire journey, we are pointing directly towards Lisbon. We have 100 NM left to run before we can officially announce ‘mission complete’. The mission being - to safely sail Greta to Europe in time for her to attend the COP25 climate conference in Madrid.
Riley and I have spoken many times this trip about the ‘mission’. About feeling like we are now part of something significant. Like this crossing had real purpose beyond the normal “go from point ‘a’ to point ‘b’” which of course, whilst so simple, is one of the true beauties of travelling by sea: purpose.
Reading back through my messages from - unbelievably - only 23 days ago, we were discussing whether I would be the best person to help him and Elayna with the trip. I wrote to him and advised he make whatever decision was best for their safety - for there was “something bigger at stake than any of us”. I ... we ... felt a pull to work together for this bigger ‘thing’. There were good reasons to choose someone else - for example, the fact that I had to fly was not ideal considering what the trip represented, even though I did buy carbon offsets. What ultimately brought us together was the pull of the adventure, yes, but also a deeper common interest - a shared purpose ...
We have had many conversations on-board about the climate emergency - about how bleak the situation is. There have been some heated discussions too - is it too late? Should we still hope? Can we feel positive? Is it constructive to be afraid? To name a few.
Every discussion for me has been informative, and interesting. I’ve learned in much greater depth about the issues at hand - and had some ideas about how to contribute to fixing them. This was one reason I agreed to be part of this and support the crew - so in my view a successful 3 weeks!
One of my favourite conversations was with Svante and Greta yesterday. We were considering how the sailing trip that we have just done - a voyage that Greta decided was necessary for her to take - is so symbolic. On departing the USA we sacrificed any control or strict agenda. We surrendered to the ocean and to Mother Nature. We relied on science - the weather forecast - to guide us. We supported science with our own instinct for survival. We gained a unique perspective of how small we are in this big world. We compromised many of at least a Westerner’s life luxuries - plenty of food, running water, fast internet access - to name a few. Despite this, we are arriving feeling richer and more fulfilled than we left.
Reflecting on what this trip was about - the bigger ‘mission’- this conversation feels extremely relevant.
Whilst it could be misinterpreted this way, this trip was not about telling people what to do, or how to live. It was not about Greta or any of us travelling in the most sustainable way possible. If it was, there were probably slightly better options - although none perfect. There may have been skippers who could have joined the boat in two days without flying. There may have been boats without a diesel engine as a back up for power. There may have been vessels that could monitor their carbon footprint more closely.
This trip was about the bigger mission. It was for us to enable Greta - one of our influencers - our role models - to travel in the way that she felt was most in line with the youth climate movement message: To highlight the need for big structural change to fight the climate emergency. To make the point that there isn’t a sustainable way to travel yet, and there needs to be.
‘Big structural changes’ - no one knows exactly what that will entail. But I think it’s so beautiful that just by choosing to sail across the Atlantic, we demonstrated that it is possible to adopt ‘big structural changes’ into our lives - even if just for three weeks. These changes surely correspond with some of the changes necessary to solve the climate crisis: trusting science, setting aside differences and working together, sacrificing some of life‘s indulgences, surrendering control, compromising, staying optimistic - finding a shared sense of purpose. By sailing across the Atlantic we have shown what it is possible to achieve if you work with nature, and not against her.
In making it to Lisbon by the power of the wind, we have in a small way, contributed to the youth climate movement. We had ‘walked the walk’ and ‘talked the talk’ so to speak. Perhaps that was our shared purpose after all … ?
It has been a privilege to have helped Riley and Elayna sail Greta and her father safely to Europe, and ultimately to her family and her home. Being part of this project is something I’ll remember for the rest of my life. It’s been an opportunity to deepen my understanding of the climate emergency; to make five new friends; and best of all, to enjoy and share the purity, the perspective, and the peace that sailing across an ocean provides.”
“If damaging tipping cascades can occur and a global tipping point cannot be ruled out, then this is an existential threat to civilization. No amount of economic cost–benefit analysis is going to help us. We need to change our approach to the climate problem. In our view, the evidence from tipping points alone suggests that we are in a state of planetary emergency: both the risk and urgency of the situation are acute.”

“Denial of that sort might be embedded in our DNA. Some scientists think it’s the primary trait that distinguishes humans from other animals. We know we are going to die, so we develop beliefs in an afterlife, or we just don’t think about it at all. And in a similar way, we don’t dwell on the fact that human activity has changed the atmosphere, and that conditions could get very bad in the near future.”
“Any industry that harms its consumers, pollutes the planet and depends for its survival on political support is living on borrowed time, though. The declines to coal-fired power on multiple continents are the death throes of a technology that’s rapidly heading towards obsolescence. Humanity will still struggle to reduce our emissions fast enough to avoid devastating climate change — but don’t be surprised if this industry falls even faster than people have dared to hope.”
