You getting the weird weather, You know? The record heat. The freak storms. The climate crisis is something we are experiencing day by day. What is going on under the surface is even more disturbing. The emergence of new scientific discovery is creating a frightening image. We are moving planetary systems to irrevertible breakdowns. It is not only about the warmer summers. It is concerning fundamental alterations to the operating system of the earth. We shall discuss those invisible tipping points which we are starting to learn.
The Point of No Return of the Amazon
The Amazon has been known long enough as the lungs of the planet. But what would it do to begin to breathe backwards? In a recent paper by Nature, satellite data and AI modeling was utilized. It proposes that there are sections of the rain forest that emit more carbon than they absorb. This beautiful revelation changes all our perception.
The guilty are deforestation and heating. They are weakening the natural operations of the forest. This provides a vicious, self-reinforcing cycle.
According to Dr. Gabriela Silva, an ecologist, who took part in the report, the process of loss of a life support system is what is being observed almost literally. The statistics indicate that the shift to the savanna at the cost of the forest is already taking place in the eastern areas.
This is not even a speculation of the future. It is a current event. The South American map is being recreated by the climate crisis.
The permafrost is considered the sleeping giant
Now, let’s travel north. Arctic permafrost is a Volcano waiting to erupt. And it is starting to wake up. Scientists who were drilling in Siberia made a chilling discovery. They measured the levels of methane 30 times more than what the model had indicated before. This methane is a greenhouse gas that is 80 and above times stronger than CO2 in the short run. It is bubbling out of the ground literally.
The implication of this finding is enormous. It may represent an excessive optimism in our climate models. They may be underestimating the rate of heating in the future.
According to one of the researchers working on the project, one of them observed that, when you hear the ground melt and methane hissing out of a new borehole, the abstract notion of the climate crisis turns sickeningly real.
The thaw is accelerating. And it is there setting a carbon bomb that we can hardly control.
Case study on the ice sheet of Greenland
Think of the great ice cover of Greenland. It is melting away at an all time pace. It lost more than 30 billion tons of ice in a span of a week in summer 2023. That alone can fill up the whole of Florida. This does not happen slowly and gradually. It is a collapse.
The most important discovery in this case is that of feedback loops. When bright and reflective ice melts it makes dark ocean or land. Such surfaces are darker and hence absorb more heat. This, in turn, melts more ice. It is the vicious circle in its momentum. A physical change of the planet is taking place. The statistics are graphic and cannot be disputed.
A Glimmer of Hope in the Discovery of the Ocean
But it’s not all dire news. The latest ocean exploration mission proved to find something amazing. Researchers discovered that there was a certain species of phytoplankton which was growing in more acidic and warmer water. These minute creatures are very effective in capturing carbon. It is a discovery of a natural discovery that might be a game-changer.
It provides an entrance to new bio-technological solutions. Maybe we can be taught by this process of nature. There is a possibility of us improving the capacity to store carbon in the ocean. This is a powerful reminder. Solutions to this problem lie in the natural world, should we seek them.
What Does This All Mean for Us?
The heavy flow of new information may be daunting. But we have to get beyond the paralysis. Such discoveries are not confined to scientists only. They are a wake up call to all of us. Policies should mirror this panic and we must demand it. We need to enable innovation that will deal with these tipping points head on.
The climate crisis is the final challenge of our overall will. Are we the generation whose data has been rolling in and done nothing? Or shall we be the one who decided to evolve, adapt and struggle to make a stable planet? The decision is being made at this moment. And we will have the next finding to make.
