Let’s talk about Stockholm

Hey peeps! I know, I know, I’ve been trying to do my best to balance private life, assignments, test, and of course this incredible space for all of us where I share sustainability-related topics. As some of you may know, here at KTH, we just entered last week the dark zone of deadlines and final exams… yay! (said no one ever), crazy never-ending reports, long assignments and preparation for exams…

But well, let’s get to the topic… Stockholm! As you all know I’ve living in this amazing city for about 7 months now… what!… ok time is going really fast hehe but I’ve learnt so many thing from it. As a leading city in sustainable innovation, Stockholm is investing in not only bright minds to spread environmental knowledge, but in the city itself to be sustainable for the next generations.

This topic is simple, I want to show you a really cool video that Stockholms Stad made for one of the most sustainable neighborhood here, Hammarby Sjöstad (pretty sure you pronounce it wrong, actually no one knows how to do it. Kidding. Not really haha). This neighborhood is being totally renovated with different insight of how to make it sustainable in all ways possible.

Weather vs. Climate

So it’s been two long weeks since I posted something (and I’m sorry for that). Christmas with family and New Year’s with friends got me at the edge of bankruptcy, gaining some extra kilos and just enjoying my beloved ones, but I’m back peeps! So much has happened since my last post… so I would like to make a comeback with something that made me almost fall down from my chair. Trump’s Dec. 29th tweet. Let’s take a look why…

This tweet is wrong in so many ways; for example, no one should ever praise or encourage for more Global Warming. Secondly, if someone dares to do it, at least I don’t expect it to be the leader of one of the most powerful countries on Earth (I assume he/she would be a high educated person who understands the complex link between Earth and human processes)… and well, the fact that Mr. Trump doesn’t understand the difference between Climate and Local Weather.

Let’s remember what climate and weather are…

Climate refers to how the atmosphere acts over a long period of time.

Weather describes what’s happening on a much shorter time scale.

Then, as our friends from the New York Times said in this article, “climate can be thought of, in a way, as the sum of long periods of weather.”

So peeps, now you know! Remember Climate Change is real and we, humans, DO NOT OWN THIS PLANET, we SHARE IT with other species so lets take care of it all together! Don’t forget to comment, share and subscribe! 😀

How Much Is Too Much?

Limits. We know about speed limits, spending money limits, and even our parents’ patience limits; but how many of you have heard about Earth’s Environmental Limits? I’m pretty sure that you have heard at least 1 of the 9 planetary limits (or better called planetary boundaries), Climate Change! But what about the other 8? As a matter of fact (maybe by my own ignorance or the fact that they are quite new), before coming to Sweden I had never heard before the term “Planetary Boundaries”.

Everything started with one TED talk from Johan Röckstrom, internationally recognized Swedish scientist, where he introduced for the first time the 9 planetary boundaries. As presented in the image below, you can find our limitations for environmental stability and well-being. Inside the blue circle we are operating within safety levels without jeopardizing our future; by adding pressure to any of the limits, we enter the red circle, or the “uncertainty area”. In this red area we start reaching a point of environmental instability (e.g. more extreme weather for climate change). Passing this circle we enter the DANGER ZONE!

Here are some examples presented by the Stockholm Resilience Center (2015) and the Global Issues paper (2014) of what crossing the red circle has done to our environment:

  • Decline in the shrimp catch in the Gulf’s of Mexico “dead zone” due to fertilizes reaching the water. -Nitrogen and Phosphorus flows boundary
  • Baltic Sea eutrophication. -Nitrogen and Phosphorus flows boundary
  • More than 40% of the global river discharge is now intercepted by large dams. -Biodiversity loss boundary
  • More than 1,500 amphibians, 1,200 birds, and 1,000 mammals among others, are threatened to be extinct. -Biodiversity loss boundary

It’s quite interesting to understand the complexity of these boundaries based on their interconnected relationship. For example, more carbon dioxide leads to global warming and ocean acidification, leading to higher temperatures and melting polar ice-sheets, acid and warmer oceans that destroy coral reefs, food and shelter for many fishes… and well, I could continue with the chain but you’ll be probably gone by then 😀

Found it interesting? Remember that everything we do has positive or negative consequences to the way we thrive.Want to know more about the limits and how they are quantified? Click here and don’t forget to leave your comments and questions!

Remember, climate change is not the only boundary we should be worry about!
