The rise in sea level — a signal that climate change is not stopped. Is it true?
Source:
sea level rise may deprive house millions of people.
As reported this week , 25 thousand people from 200 countries gathered in Madrid to find a solution to the problems associated with . According to the UN Secretary-General, antónio Guterres, the point of no return is the horizon. However, no matter how intimidating did not seem this statement, we can still avoid catastrophic consequences — for this it is necessary to drastically reduce emissions of carbon dioxide. At least that is the goal of the annual conferences on climate change. But there is a small problem: as the result , we have already passed one point of no return, which should encourage us to pay more attention to adaptation to climate change.
We are Talking about the third IPCC report, which is in September. explores the status of the seas and oceans, and the findings of scientists are disappointing — every year the water level rises faster. If the water level will rise twenty meters, enough to flood vast tracts of coastal areas, depriving the house of hundreds of millions of people. However, while sea-level rise was relatively small, however, since 1993 the situation has deteriorated significantly.
The Researchers note that we have not yet observed the catastrophic sea level rise as the climate gradually responds to increased CO2. Moreover, the catastrophic growth will occur over centuries, not decades. And it is certainly good, as we have time to prepare. But there is also the flip side of this somewhat encouraging picture: the climate will inevitably change. Today the world is suffering from prolonged periods of intense heat, intense storms and forest fires. And the concentration of CO2 in the atmosphere reached a record high in 2019.

What's happening with Greenland and the Arctic?
Due to climate change the Arctic has been affected more than other regions, heating up two times faster than the rest of the world. This is reported by the researchers in a paper published in the journal . The results showed that the current warming will lead to a more rapid reduction of Arctic sea ice than is assumed by most models. This in turn will affect sea level rise. Moreover, scientists are concerned about the state of Greenland, which is rapidly losing ice cover than contributing to sea level rise. Work on the state of the ice sheet of Greenland can be found in the journal .
Greenland is rapidly losing ice cover
However, despite the fact that the rise in sea level will occur over a long period, if today you are not taken necessary measures, we will not be able to adapt to global warming. Some researchers do not hide their pessimistic attitude and say that we have neither the time nor the resources to adapt, considering the urgent need to mitigate future impacts. Recall that the climate change today affects the health of millions of people around the world. Only in 2016 weather extremes did climate refugees about 23.5 million people. And that's not including people who are forced to leave their homes by droughts, rising sea levels and melting of permafrost.
The Inability of world leaders to help people to adapt to this kind of didn't feel right. Let's hope that scientists and heads of state will be able to take all the necessary measures.
