Berit Svendsen held a great presentation about how to be the leader of one of the largest companies in Europe, Telenor. I was backstage at the time, so only got to hear the start though...
Ailo Gaup (left) contributed with his fantastic story of overcoming challenges and pain to follow his passion: FMX. Pain being very literal, as he has suffered several bad injuries through his sport: breaking 35 bones is just one example... As a world champion in motocross, he mesmerized the audience with his story of never giving in and keep chasing his dreams against all odds. Visit his website here.
Francois El-Safadi (right) shared his experience and wisdom, transferring his endless energy to all 500 participants. He works actively against injustice and to help the weakest in society. The wonderful passion for helping others, living in the present, building relations and the "just do it"- mentality are important values to remember from his presentation! A quote I found on his website sums up his striking personality:
"Weather is a metaphor for life - sometimes it's good, sometimes it's bad, and there's nothing much you can do about it but carry an umbrella".

Today, as Asian growth is just getting into its stride, world food production is already under pressure. Food prices are rising rapidly and, although it is nothing but an annoyance to us, it has a massive impact on poor people who spend the majority of their income on food. Close to half the world's population survives on less than $2 a day. Compare that to your daily food intake to get some perspective.
Grains provide half of the world's caloric intake, but yet, we currently feed a third of our grains to livestock and use a sixth of it for biofuels. Global food demand will triple by 2050, Chinese meat consumption is doubling every seven years and biofuels might be our only hope when peak oil hits. Oh, and then there are of course the potentially disasterous effects of climate change on agricultural output…
Eating and living sustainably saves lives. And your own health, which is a decent bonus...
This is very dangerous. Every planetary boundary we cross affects the others and reduces the rate at which our planet can generate resources and process wastes. If we keep this up, the death phase of the bacterial growth curve discussed in the previous post is inevitable. This is an irrefutable scientific fact.
We still have a choice though – a rather obvious one. It's just that I sometimes wonder if we will ever be bothered to make it…
We have only one home – planet Earth – and this planet has a finite amount of resources, a fixed boundary that cannot be crossed.
Humans seem totally oblivious to this fundamental limitation, however, and we have created for ourselves a society that is completely dependent and totally addicted to exponential growth. I'm sure you have learnt about the fate of this kind of society in high-school biology when you grew a bacteria culture in a little Petri dish…
The bacterial growth curve has four main stages: a lag phase, an exponential growth phase, a stationary phase and a death phase.
We are certainly not respecting the boundaries of our little planet Earth even though all the evidence suggests that we should have slowed down years ago. Seemingly oblivious, we simply to consume resources and excrete wastes at an ever increasing rate.
If you look at the human population growth history, we are now at the start of the stationary phase. You know what comes next…

Beneath the oceans lies more methane than we can ever imagine, frozen under low temperatures and massive pressure. If the oceans warm, however, these methane hydrates will become unstable, return to gaseous form and rush to the surface to cause all sorts of havoc.
Methane is a 22 times more potent greenhouse gas than CO2. Large scale methane hydrate release would almost certainly push the earth to the 6 degrees doomsday scenario and keep it there for centuries.
Methane is also flammable at relatively low concentrations and a massive concentrated release can be ignited by natural phenomena like lightning to explode with the force of several nuclear bombs, vaporizing everything within a radius of several kilometres.
Methane hydrate release is speculated to become an irreversible climate change driver at 5 degrees of warming. For the sake of future generations, let's make sure we never get there.
Many climate scientists fear this one the most. The amount of greenhouse gasses locked up in the vast expanses of permafrost in the high northern latitudes is in the order of 100 years' worth of human emissions.
In the video attached to post 4, we saw the disproportionate amount of heating taking place within the Arctic Circle due to the melting ice and large land masses in this area. The permafrost time bomb is therefore very inconveniently located and is projected to explode irreversibly at 4 degrees of warming.
The term "irreversibly" means that we will be powerless to stop it. The massive source of carbon will release more greenhouse gasses than we ever could and, in order to have any chance of maintaining a functional society, we will have to do insane sounding things like launch millions of mirrors into space or paint our entire world white.
A much better idea would be to avoid the tipping points in the first place...
