What level of confidence does the IPCC have that climate change and changes in land use are key drivers of ecosystem loss?

The Intergovernmental Panel on Climate Change (IPCC) assesses the confidence level regarding various aspects of climate science based on the strength and consistency of the evidence available. In the case of climate change and changes in land use being key drivers of ecosystem loss, the phrase "high confidence" indicates a strong consensus among the scientific community that these factors significantly contribute to the degradation of ecosystems.

The term "high confidence" means that there is robust evidence and a pronounced agreement in the literature and among experts, but it might not reach the highest possible degree of certainty (which is "very high"). This level also signifies that while there may still be some uncertainties or variables at play, the overwhelming data supports the idea that climate change and land use alterations are crucial factors in ecosystem loss.

This nuanced understanding of confidence levels allows stakeholders, policymakers, and the global community to make informed decisions based on the likelihood of various scenarios regarding environmental conservation and climate action.
