Why is the IPCC assessment report important?
The IPCC was created to provide policymakers with regular scientific assessments on climate change, its implications and potential future risks, as well as to put forward adaptation and mitigation options. Through its assessments, the IPCC determines the state of knowledge on climate change.
Can the IPCC be trusted?
If it was not clear yet, the answer to “can we trust the IPCC?” is obviously YES. As a reminder, the IPCC only synthesizes the available scientific knowledge on the various subjects of climate change. This synthesis is a consensus and is validated by all member governments.
What is a major conclusion of the 2021 IPCC report?
The report finds that the chance of exceeding tipping points, such as sea level rise due to collapsing ice sheets or ocean circulation changes, cannot be excluded from future planning. Their likelihood increases with greater warming.

Global warming will jeopardize food security, as well as increase the incidence of heat-related mortality, heart disease and mental health challenges. For example, under a high emissions scenario, increased flood risk could lead to an additional 48,000 deaths in children under 15 years old in 2030, due to diarrhea.

How long do we have before climate change is irreversible?
This paper shows that the climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop.
Why is the IPCC credible?
The IPCC’s technical reports derive their credibility principally from an extensive, transparent, and iterative peer review process that, as mentioned above, is considered far more exhaustive than that associated with a single peer-reviewed publication in a scientific journal.
What is the IPCC report and why does it matter?
Reports. The IPCC prepares comprehensive Assessment Reports about the state of scientific, technical and socio-economic knowledge on climate change, its impacts and future risks, and options for reducing the rate at which climate change is taking place.
Why is the IPCC report important?
What does the IPCC predict?
The IPCC Working Group I sixth assessment report shows that the world will probably reach or exceed 1.5 degrees C (2.7 degrees F) of warming within just the next two decades. Whether we limit warming to this level and prevent the most severe climate impacts depends on actions taken this decade.

The conclusion that much of the warming over the past 50 years is due to human activities is now “extremely likely,” upgraded from “very likely” in the last report. Estimates of future sea level rise have been significantly increased due to a better understanding of the movement of ice sheets in a warming climate.
