Meaning: The quote you provided is attributed to Nils-Axel Morner, a Swedish sea level expert and geologist who has been critical of the Intergovernmental Panel on Climate Change (IPCC) and its handling of sea level rise research. In this quote, Morner is expressing his skepticism about the IPCC's approach to addressing sea level questions and their alignment with what he perceives as modern knowledge of sea level change modes and mechanisms.

Nils-Axel Morner has been a controversial figure in the scientific community due to his skepticism about the extent and causes of sea level rise attributed to climate change. He has argued that the IPCC and other organizations have exaggerated the threat of rising sea levels and has been vocal in his criticism of their methodologies and conclusions.

Morner's critique of the IPCC's handling of sea level questions suggests that he believes their approach is flawed and does not align with what he considers to be the most up-to-date understanding of sea level change. His use of the term "cannot be accepted" implies that he views the IPCC's conclusions as unacceptable or invalid, while his reference to "modern knowledge of the mode and mechanism of sea level changes" suggests that he believes there is a more accurate and credible understanding of sea level dynamics that the IPCC is not incorporating into its assessments.

It's important to note that Morner's views are not universally accepted within the scientific community, and many climate scientists and researchers disagree with his assessments of sea level rise and the IPCC's findings. The overwhelming consensus among climate scientists is that sea levels are rising due to global warming and the melting of polar ice caps, which are in turn caused by human activities such as the burning of fossil fuels and deforestation.

The IPCC, as a leading international body for assessing climate change, has produced numerous reports on the impacts of global warming, including the rising sea levels. These reports are based on the collective work of thousands of scientists and researchers from around the world, and undergo rigorous peer review to ensure their scientific accuracy and credibility.

In response to criticisms from Morner and others, the IPCC has defended its methodologies and findings, stating that they are based on the best available scientific evidence and are subject to thorough evaluation and review. The organization has also acknowledged the complexities of sea level rise dynamics and the challenges of accurately projecting future changes.

It's important for individuals to critically evaluate different perspectives on complex scientific issues such as sea level rise and to consider the weight of evidence and the consensus among experts. While dissenting voices like Morner's should be heard and considered, it is also crucial to recognize the broader scientific consensus and the extensive body of research that supports the understanding of human-induced climate change and its impacts on sea levels.

In conclusion, Nils-Axel Morner's quote reflects his skepticism about the IPCC's handling of sea level questions and their alignment with what he perceives as modern knowledge of sea level change modes and mechanisms. His views are controversial and are not universally accepted within the scientific community, where there is a strong consensus that human-induced climate change is causing rising sea levels. It is important for individuals to critically evaluate different perspectives on complex scientific issues and to consider the weight of evidence and the consensus among experts.
