The collapse of civilization is almost inevitable at this point, unless capitalism is overthrown. Now scientists say that we crossed the tipping point after which the Earth’s climate is spiraling out of control. Scientists now say that “a cascade of climate tipping points is possible”; that means that the planet is crossing a number of tipping points, all reinforcing each other, as each one contributes to a run away climate change.
Here are some of these tipping points:
1.Greenland, the arctic, the West Antarctic ice sheet, and the ice in Wilkes Basin, and the ice in East Antarctica: are all melting faster. This means meters of rising seas that could kill many millions of people and cause a massive destruction of nature.
2.Permafrost Thawing. This means that even the oldest forms of ice is melting. Together with escalating ice melting in the Arctic and Antarctica, melting can cause massive rise of seas levels that could overtake many coastal cities and cause mass migration never seen in human history before. The massive melting of ice could propel sea rise on the scales of meters, not millimeters or centimeters.
3.Amazon rainforest death, and Boreal forest death. The Amazon is experiencing another draught due to climate change, as humans massively set fires in the Amazon for crop and cattle. The drying Amazon and its exposed ground are becoming a CO2 emitter, as the absorption of greenhouse gases by the forests is diminished. This cause further warming. Because of the critical importance of a healthy Amazon for the stability of the world’s climate, this process alone can cause a climate change of catastrophic proportions. The boreal forests throughout the world are dying, because of pests and fires.The warmer climate bring more pests that kill trees, and it creates a spiral loop of warming. A similar process is taking place in California and other mediterranean climate zones throughout the world.
4.Atlantic circulation slowdown since 1950s. Together with others circulatory currents, the Atlantic circulation is slowing and becoming erratic. The change of massive sea currents circulations throughout the world is guaranteed to speed up climate change in unpredictable ways.
5.The die-out of coral reefs throughout the world. Together with the acidification of the oceans, fish and other life in the oceans are beginning to disappear. In past extinctions, and in particular in the great die-out of 90 percent of life in the Permian extinction, 250 million years ago, the warming of lifeless oceans were key for the mass die-out in lands as well.
- The speed of climate change. Never in the entire history of Earth, climate change was so rapid as it is today. In the past climate change (excluding the die-out of life when a meteor crushed into Earth) was measured in thousands of years. Under capitalism, rapid Climate change is measured in years, not even decades. That means that species have no time to adapt to the rapid warming and the changing environment, and they die.
These are only some of the causes for climate change. They all connected to each other, as they spiral out of control. For example, a warming climate brings a growing number of pests kill forests. Dead forests emit massive amount of greenhouse gases into the atmosphere. This causes additional warming of the planet. Warmer planet invites more pests to destroy forests. This process creates loopback cycles that bring more greenhouse gases into the atmosphere, as the loopback cycles contribute to the runaway out of control climate warming.
The only positive thing about Climate Change, is the creation of a mass movement against climate change with massive demonstrations and strikes, primarily by young people who are going the bear the worst effects from climate change. But time is running out fast.The only hopes is the entry of working class into the struggle against climate change. But the workers cannot just go on sporadic one day strikes. There have to be coordinated working class actions that should culminate in a world revolution that overthrows capitalism, that is the main culprit for out of control climate change. It have to happen fast or life will disappear within years, or at most, few decades.
