Vulnerable systems around the world today
199 comments
We’ve already mentioned a few examples of vulnerable systems around the world that could one day pass a tipping point due to climate change. In the diagram above, I’ve outlined some others that I think we should keep an eye on, overlaid on a map of the number of people that might be affected by the changes.

Over the next few articles, we’ll be exploring three in greater detail:

Arctic Sea-ice Loss
Dieback of the Amazon Rainforest
Reorganisation of Circulation Systems
That doesn’t necessarily mean they are the most likely to happen, or that they will offer the biggest impacts.

Before we begin, let’s take a step back and think about what you already know about these systems. Reflect on what you’ve learnt so far about systems, perturbations and tipping points and consider what might be the forcing factors in these vulnerable systems around the world.

Post your thoughts in the discussion section or, if you’d like to talk about multiple systems, perhaps a blog post to expand on your reflections. There’s no need to do extra research for this activity, as we’d like to know how much you already know about parts of the Earth system and the forcings that might lead to their eventual tipping.

Kindly keep checking in,
Thank you 😊

Plant a tree, save the future through Climate Action

 The World today suffers great chaos, from Climate Change. Let's plant a tree, send out some more oxygen for our atmosphere, a tree planted anywhere, it's pride grows over the entire Globe because the Atmosphere is one, and all connected through wind streams. Unlike life on the Geosphere, where a change somewhere could be obstructed by barriers such as mountains, trees, water bodies etc, to reach the other end, but the atmosphere, is a system that needs our togetherness for tree life.  What if, we looked into reactions like the displacement in Science, and focus on raising the Oxygen levels, who knows it could help in some way, deter the atrocious impacts of Greenhouse gas, and help healing of the Ozone Layer, furthermore, taking the Globe back to its health state.  Let's talk it, let's live it, let's make it stand and live through. Together, we can achieve greater because together is more effective in everything, for the coverage is more wider reached than by one o

Enough hurt on mother Earth ✊

You never get convinced it's night time, until you see the darkness around charging at 360°, but at times you just never have to get so limited to the ignorance against going beyond determination, that's when you get to look at that "tik-tok tik-tok" sound, and look at the watch, reading it's already time for the darkness to get gas in the engine🤔.  When you look at the picture, you see a poor little innocent gugu guy walking after the mother, so blank of the future and thinking it's the way life is, yeah 😄.  Unfortunately, it's getting dark but this kind of a darkness, you can't see it just like the darkness you and I think of straight from the term. Mother Earth is sickling🤔😔, and this darkness is that, which rolls by the term, "Climate Change"🤨.  Alright, No fingers can work right now from any angle rather to any angle, because the only pointing of the fingers now, we need, is to make a "difference" you can.

The Bottom line - Humanity #ClimateAction

Let me try bring up some conscious into viewpoint.. When you look at the seas and oceans, the lakes and Rivers, streams and plains.. You will notice waves, in times, from the surface of these "secrets of life".. the Air takes on its pride as flys over them.. When you hear of thunder rumble!, Just know it came through from deep in the silence, of the silent "air".. When you get freaked out by lightning, just know it came through behind the back of your conscious, crunching at your presence, as well all through the silence, and that Agent through it's pride made lightning roahring like a lion. That agent, the "AiR".. Now, when you hear the trees flipping the branches and beautifying the nature around, through leaves and Alike.. Just know this messenger, takes the pride of it's nature around.. the "AiR" as the "Bottom line" of all these Earthlings 😊... As I look more closely over it all.. I see a Being... walking like oth
