“Tipping points…”

*squints at computer*

Before we start going through the deep process of learning the serious problems of tipping points related to climate change and how they seriously affect our planet, I think it would be a good idea to first let you guys understand what are tipping points, related to climate change, actually mean.

A climate tipping point is a somewhat ill-defined concept of a point when global climate changes from one stable state to another stable state, in a similar manner to a wine glass tipping over. After the tipping point has been passed, a transition to a new state occurs.

If that was sort of a blur to you, then it’s best you know an example. Would you believe me that over 6,000 years ago that Sahara desert was filled with trees, rivers and filled with vegetation? This was the Sahara’s “green” era, where everything was filled with water holes, according to studies and evidence found at an ancient cave which used to be surrounded by glorious amounts of water. Yes, the desert we all know as the largest hot desert in the world, was once filled with green, green and green. It has surprised many, as it changed abruptly, from cool and humid weather to blazing, hot sun. This is one example of a tipping point.

Time for the real stuff.

Ilissa Ocko, a scientist who explains mostly about climate change, has written a blog, on Environmental Defence Fund, about 6 of many of our worlds climate tipping points that she suggests scientist should worry about most. Here are three out of the 6 climate tipping points we all should worry about:

  1. The Arctic sea ice melts
    • Ilissa’s explanation to worry about our ice melting:The melting of the Arctic summer ice is considered to be the single greatest threat, and some scientists think we’ve already passed the tipping point.As sea ice melts and the Arctic warms, dark ocean water is exposed that absorbs more sunlight, thus reinforcing the warming. The transition to an ice-free Arctic summer can occur rapidly – within decades – and this has geopolitical implications, in addition to a whole ecosystem being disrupted. In my opinion:                                                                                                                                                                                                                                                                                           I highly agree as to what Ilissa is saying but I’d just like to give my own input and add on for more reasons on why we should worry about our ice caps melting. First, I’d always like to think about the world like a domino game, well, they have a term, it’s called dominos effect, it’s when one act or event leads to more or multiple other events, like a chain. As I was saying, when I think about the ice melting in the dominos effect, it leads to multiple disasters:                                                                                                                                                                                                                                     ICE MELTING (DOMINO EFFECT)
      • Polar Bears lose most of their home!
        1. Isn’t this terrible! We have enough endangered and extinct species in this world.
        2. According to  the U.S. Geological Survey projects, we will lose 2/3s of our polar bears by 2050
      • Water rises
        1. This, we should all understand, puts us in a grave position.
        2. Less salt water in the ocean
          1. Animals adapted to the salted water will be affected as more none salted water rises throughout the ocean
          2. Whole ecosystem being disrupted (from Ilissa)
        3. Water levels in beaches rise to much and ends up destroying nearby houses
          1. Government pays for helping locals who stay at beach front to go up to a more elevated level
        4.  Cities streets get more flooded
          1. Sewage problem
        5. Trash from ocean starts spreading everywhere
        6. Venice sinks more
      • MORE PROBLEMS!
      • Also, the snow that are peacefully laying on the ice caps help reflect a great amount of light back into space which helps balance out the climate change and when that melts that causes us an even greater problem in our climate change!
      • DOMINO EFFECT, GUYS! DOMINO EFFECT!                                                                    
  2. Greenland becomes ice – free
    • Ilissa’s good explanation to worry about Greenland becoming ice – free:                                                                                                                                                                             The warming of the Arctic may also render Greenland largely ice-free. While Greenland’s ice loss will likely reach the point of no return within this century, the full transition will take at least a few hundred years.The impacts of the Greenland ice melt is expected to raise sea levels by up to 20 feet.Half of the 10 largest cities in the world, including New York City, and one-third of the world’s 30 largest cities are already threatened by this sea level rise. Today, they are home to nearly 1.8 billion people.

      Other vulnerable American cities include Miami, Norfolk and Boston.

    • Hey, it’s me. If you haven’t heard about the story and how greenland is actually all icy and iceland is actually all green then you should know. Now you shouldn’t be as confused, at the start, like me ^__~. I’d like to explain the story of greenland and iceland but that is for another story for a later time. Just stand by. But, remember I mentioned a couple of sentences ago about the domino effect, which I am super addicted to, well, if you read closely on what Ilissa’s is saying, then you should notice that she mentioned the sea levels rising, almost, through the roof (I mentioned about the sea levels in the domino effect).           
  3. The West Antarctic ice sheet disintegrates
    • Ilissa’s view:                                                                                                                                                                                                                                                                                               On the other side of Earth, the West Antarctic ice sheet is also disintegrating. Because the bottom of this glacier is grounded below sea level, it’s vulnerable to rapid break-up, thinning and retreat as warm ocean waters eat away at the ice.Scientists expect the West Antarctic ice sheet to “tip” this century, and there is evidence that it already began happening in 2014.However, the entire collapse of the glacier, which would raise sea level by 16 feet, could take a few hundred years.
    • I have a suggestion for you to watch the documentary about climate change that Leonardo Dicaprio (Yes, the actor) has put together with his “crew”. The video is eye – opening and will change your view on climate change. In the documentary, Leonardo visited Greenland and Artic and you would see in the video surges of strong water would melting out into the ocean. We all learned from his documentary that Greenland and the Artic are both on their way to melt completely, and, Greenland is presently entering a journey into an irreversible feedback loop of melting.

But, you know, after all the problems listed out here, it’s amazing how we can help out. Just, by doing the simplest things, like, spreading the word, we could help.
