mainly through the emission of greenhouse gases
, have unequivocally caused global warming," says the sixth synthesis report from the Intergovernmental Panel on Climate Change (IPCC).
A well-known statement, but one that year after year, with scientific advances, is confirmed again.
This Monday, the agency's new summary report came out.
Hundreds of specialists worked on it, compiling the scientific information published in recent years - the previous report, the fifth, came out in 2014.
This new report gathers the scientific data that governments must use to develop their climate policies to mitigate and reduce emissions, but also to adapt to the changes that are already being experienced.
Human-caused climate change already affects temperatures and intensifies weather events in different parts of the planet, this new synthesis report reaffirms this.
The heat waves experienced in the country from the end of 2022 until last week, especially their recurrence, are an example of this.
Heat waves have become more frequent and intense in most regions since the 1950s
, while cold waves are less frequent and intense," states the report of one of the IPCC working groups.
At the press conference for the new report, the executive director of the United Nations Environment Program (UNEP) Inger Andersen said: "Climate change is here, threatening humans and the planet, whose well-being is one and the same. "
We have the technology and knowledge to reduce emissions and tackle climate change.
Renewable energy instead of fossil fuels, restoring ecosystems and reducing waste from the food system."
Antonio Gutiérres, Secretary General of the United Nations, at the press conference for the sixth IPCC synthesis report.
"Until now, we have collectively failed to end greenhouse gas emissions. We are very close to the 1.5°C limit - the global average temperature rise limit set by scientists which, while it would imply serious changes on the planet, it would still allow for general well-being," Andersen said.
We have to leave climate procrastination to move on to climate action and we have to start today
," she closed.
The report points out the crucial role of governments at the regional, national and international levels as those in charge of carrying out the necessary policies to reduce emissions.
In addition, civil society and companies also play a fundamental role demanding climate action and incorporating it.
"Climate change is a threat to human well-being and the health of the planet.
There is still a window of opportunity
- which is rapidly closing - to ensure a livable and sustainable future for all
", concludes the sixth synthesis report.

What is the IPCC
The Intergovernmental Panel on Climate Change -IPCC for its acronym in English- is
the United Nations body for evaluation, analysis and verification of science related to climate change.
Their task is to provide governments with the scientific information they need to develop their climate policies.
This body was created in 1988 by the United Nations Environment Program (UNEP) and the World Meteorological Organization.
The IPCC reports on the causes, risks and future impacts of climate change, as well as options -based on the best existing science- for the adaptation of societies to it and mitigation - changes in activities whose objective is to reduce emissions of greenhouse gases.
The fifth IPCC report was published in 2014. Since then, the agency has produced three special reports and three new reports that bring together the advances in research on the subject.
In 2021, the report that gathers new data on the physical bases of climate change came out.
In 2022, the report on impacts, adaptation and vulnerability came out first, and then on climate change mitigation.
The publication of the
sixth IPCC synthesis report
integrates the materials of the publications after 2014 -the six mentioned reports-.
The objective of this report is
to establish the scientific bases for the climate policies that governments must adopt.
