great barrier reef bleaching

In my previous post I briefly mentioned the most recent bleaching of the Great Barrier Reef.

A few people reached out and asked what that actually means. Happy to give you more details on this. Firstly, it’s not good news at all.

Corals are thermally sensitive, meaning that they can only tolerate small temperature ranges. However, climate change is causing abnormally high sea-surface temperatures, which is causing corals to bleach during summer months. The intensity of coral bleaching increases as temperatures become hotter.

Zooxanthellae are tiny, colourful marine algae, which live inside corals, providing them with much of their colour and, most importantly, their primary supply of energy. However, if the surrounding sea temperature becomes too warm, the algae die.

The loss of these zooxanthellae is what is referred to as ‘coral bleaching’.

Why are corals so important other than that they are nice to look at? Healthy coral reefs are among the most biologically diverse and economically valuable ecosystems on earth, providing valuable and vital ecosystem services. Coral ecosystems are a source of food for millions; protect coastlines from storms and erosion; provide habitat, spawning and nursery grounds for economically important fish species; provide jobs and income to local economies from fishing, recreation, and tourism; are a source of new medicines, and are hotspots of marine biodiversity.

This year, the Great Barrier Reef — the world’s largest reef system, spanning more than 344,400 square kilometers — suffered its third major bleaching event in the last five years. Previous ones took place in 2016 and 2017, with the 2016 event considered the most severe.

However, this year’s bleaching is proving to be the most extensive. A group of researchers has just updated the latest 5 year projection for the Great Barrier Reef from poor to very poor.

There’s really no time to lose to reduce greenhouse gas emissions and the Australian government is not pulling its weight in that regard. Which is quite astonishing in itself as 70% Australia’s GDP is coming from the services sector within which tourism is a large proportion.

Weird, don’t you think?

Let me know in the comments what you think.

tobi & mobi dee – the book

For the last two years I have been working on my next book. It looks like it will be ready to be published in April or May this year.

Sign up for my newsletter if you like to receive a notification once the book is about to be published.

Tobi & Mobi Dee – The Secret of the Arctic Ice – is a story about a young sailor Tobi and his best – whale – friend Mobi Dee. The two were born at the same time and have been traveling the Seven Seas ever since. While Tobi lives on his sailing boat SV Rainbowchaser, Mobi Dee swims along during their adventures.

Through a magic event in his childhood Tobi speaks “whalish” and is able to communicate with his best friend.

In this book Tobi and Mobi Dee get a request for help from their friend Franz, a one-tonne walrus, who lives in the Arctic Circle. Franz is worried about the amount of Ice that keeps on disappearing around his family home.

This is not just a story about two friends and their adventures but aims to educate young readers as they follow the story. Kids will learn about sailing, wind, weather and ocean related terms and are immersed in a story that uncovers climate change related issues and solutions.

The book is the result of bedtime stories I told my own kids that were deliberately spiked with some real life sailing and climate knowledge.

Time is always moving on, Nothing can stop it. The question is whether we use our time properly or not. We can’t do anything about the past, but what happens in the future depends on what we do now. Dalai Lama

If you, like me, live in Australia you will have noticed that we have a few fires going on here at the moment. Bushfires, not BBQ fires. If you don’t live in Australia you will have come across the global media coverage, unless you live on the moon that is.

brainblurb – the most useless product

Warning. This is a rant post.

Today is one of those few days where it actually rains in Sydney.

In case you would like to know, Sydney has 236 days a year sunshine. The remainder being days with rain. However, a shower only ever lasts 30-60 minutes.

With that and the general environment in mind I would like to introduce to you the most useless product ever invented. At least in my opinion.

Drum roll.

Here comes the umbrella bagging station usually found at entrances of larger offices, banks or shopping Centers.

If it is raining and you enter the building you are supposed to fold up your umbrella and bag it in one of those long plastic cover condoms.

To avoid water dropping from your wet umbrella onto the precious floor. Yes.

What an utter bullshit. Such a waste of money and resources. Especially following the plastic shopping bag ban you now get a free plastic bag for your umbrella; which you’ll use for 15min and then dispose of 👍

Anyone giving me any of this, “yeah but this is about safety, someone might slip and break their neck because of your water drops…” bullshit, please consider this: you just managed to walk through the rain without falling on your face.

If you ever met my grandma you know how to properly shake an umbrella dry before you enter a building.

Rant over.

PS – don’t use these things.

humans eat plastic

Humans don’t run on information.
Humans don’t make decisions on facts.
Humans don’t spend money based on data.
Humans run on feelings.

It has always been like this and will never change. Never.

Much more intelligent people than me figured this out. Dead and alive. Freud, Bernays, Plotinus, Socrates…

Here is only one example why the above is true.

The majority of the people in first world parts on this planet are aware of the fact that we have too much plastic in our oceans. That in itself is pretty uncool. 

You know the swimming in plastics, poor fish and turtles dying and so on. Then you add the fact that micro-plastics make their way from the ocean (via fish, rain or drink water) into the human food chain and you know that plastic in general is a pretty crap product.

At this very moment the majority of the people mentioned above will be shopping for plastic wrapped products and carry them home in plastic bags.

Humans don’t run on information.
Humans don’t make decisions on facts.
Humans don’t spend money based on data.  

Humans run on feelings.

brainblurb – why we keep the lights on?

The advantages of IOT in large buildings are pretty obvious – when heating and cooling systems, lighting, elevators and security are connected and controlled by a centralised solution, the potential returns on investment — in time and money saved, in more efficient usage, and in environmental impacts — are great.
