This is no longer a joke.
The reason for this is emissions generated by burning fossil fuels, the development of building infrastructure, plant cultivation, and the transport of goods around the globe. 2019 not only broke all records, but also a gateway to progressive global warming. The oceans that are responsible for absorbing 90 percent of the excess heat currently have the warmest recorded temperatures. Over the past 150 years, the level of water acidification on our planet has increased by as much as a quarter.
The matter goes a step further. In October this year, the global average sea level reached its highest level in history. All this in connection with the rapidly melting Greenland ice sheet, which has lost over the past 12 months 329 billion tons of ice.
What does this mean for people? Already, in the first half of 2019 over 10 million people have been internally displaced. 7 million of them in connection with extreme weather phenomena such as storms, drought or floods. By the end of this year, the number of residents who will have to change their homes can reach up to 22 million.
How to prevent this?
Madrid is currently debating what can be done together for the climate as part of an international agreement. The goal is to reduce global temperature rise below 2 degrees by the end of the century. To achieve this, humanity will have to reduce greenhouse gas emissions, as well as rebuild the economic governance patterns: mainly in the context of the use of renewable energy.
Part of the discussions taking place in Madrid is to encourage the countries concerned to increase their ambition in the fight against climate change. Friederike otto, deputy director of the Institute of Environmental Change at Oxford University, however, cools the mood. "As humanity we are not adapted to warming by 1.1 degrees, let alone by 3" – said the scientist.
If humanity continues to operate as before, climate change will start accelerating rapidly. The situation will also affect Poland. It is estimated over several decades Szczecin and Bydgoszcz may find themselves underwater. We can also lose places from Gdańsk to Krynica Morska. So there are no jokes.
However, this type of change will affect not only Poles, but also almost 750 million people around the world in a similar situation in large urban agglomerations. Currently, there is no indication that global warming has disappeared.
However, we still have some time to stop them effectively.
