Scientists prepare announcement of new evidence on climate change

The IPCC, the scientific entity that generates the data that guides the world on how to respond to climate change, today began a two-week meeting for the final review of a report that it will deliver to governments on the 28th and that will contain new evidence. on the socioeconomic aspects of this phenomenon, its relationship with biodiversity and will recommend that the local and indigenous knowledge that exists in this regard be valued.

"We are in the final phase of a strict and meticulous review of the report that assesses the impacts, adaptation and vulnerability to climate change"explained the president of the Intergovernmental Panel on Climate Change (IPCC), Hoesung Lee, at the opening of the meetings, after which the discussions will be held until the end behind closed doors.


This will be the second chapter (of a total of three) of the Sixth Assessment Report on climate change, a document that is being prepared over six or seven years to incorporate the new information that is being obtained on climate change and that guides international decisions and commitments at the climate change summits that take place every year.

In the last one, held last November in Glasgow (United Kingdom), the commitment to limit the rise in global temperature to below 1.5 degrees Celsius was kept alive, an objective that is increasingly difficult to meet due to the constant increase in gases that cause global warming mainly due to the use of fossil fuels.

Science has shown that a further rise in global temperature would cause more extreme weather events, increase food insecurity and put more pressure on water resources, among other serious consequences.


In this final phase of revision of the second chapter – which contains thousands of pages and whose preparation involved 270 scientists from 67 countries who have worked on it without receiving payment in return -, the government representatives will meet electronically with the authors to do a review "line by line" of the document, in a scrutiny process that will guarantee the accuracy of the data and its balance.

The first chapter was presented last August and focused on climate change projections, while the chapter that will be presented in two weeks will focus on understanding the interconnection between climate, biodiversity and human societies, and will offer solutions no longer not only at a global level, but at a local level, so that people are better able to respond to climate change at a community level.

Although the language of these reports usually puts it out of the reach of ordinary citizens, its content is crucial because it constitutes the scientific foundation that no one can reject on the progress of climate change and offers governments a concrete guide for the actions that they are required if societies are to be able to accommodate themselves to the new situation and maintain their existence.


Opening the meetings, the Secretary General of the World Meteorological Organization (WMO), Petteri Taalas, raised a different point of concern, related to the impact that the climate change debate is having on the mental health of youth, a matter that he suggested to take into consideration.

He noted that the "apocalyptic fear" is spreading especially among the youngest and in the face of this "we must carefully communicate the results of our scientific research".

Taalas, whose organization also researches and produces data that help understand climate change trends, emphasized that talking about "biosphere collapse" or of "extinction of humanity" it can only generate despair among young people.
