It is difficult to argue with the fact that the Earth's climate has undergone significant changes. The UN Intergovernmental Panel on Climate Change has collected a huge amount of observations, theories and articles on the rise in global temperatures. The main cause of climate change in our time is greenhouse gas emissions.
One of the goals of the Paris Agreement on Climate Change is to keep the global temperature from rising to 2 °, and limit it to 1.5 °. But the global temperature of the planet continues to rise. Despite the prevention of carbon dioxide emissions through the use of alternative energy sources, restrictions on greenhouse gas emissions, the growth rate of greenhouse gases in the atmosphere remains high. This raises the question, what will happen if we stop greenhouse gas emissions right now? Will this stop the rise in temperature? Will our planet return to its former stable climate system? The simple answer is NO.
By releasing greenhouse gases into the atmosphere, humans allowed them to accumulate and move freely. Even if humanity stops all emissions today, it will take the planet thousands of years to reduce the amount of greenhouse gases that it already has. True, scientists assume that in 40 years the climate will be able to stabilize, at temperatures higher than for all previous generations.
This long-term lag between cause and effect is due to the fact that it is easier for the energy trapped by greenhouse gases to heat the air than water. As soon as the water temperature rises, a new stage of global changes will begin. Having started the process, it was not in our power to stop it.
In any case, it is now impossible to stop emissions of carbon dioxide, which means that we should prepare for the new consequences of global warming. The slower the planet warms up, the more time humanity and the entire living world will have to adapt to changes.
