Multiple independent studies exist but conclusions do not agree.

Something difficult or impossible to foretell or foresee.

The IPBES Units of Analysis result from subdividing the Earth?s surface into units solely for the purposes of analysis. The following have been identified as IPBES units of analysis globally:Terrestrial:Tropical and subtropical dry and humid forestsTem.

The IPBES Units of Analysis result from subdividing the Earth's surface into units solely for the purposes of analysis. The following have been identified: IPBES units of analysis (terrestrial): Tropical and subtropical dry and humid forests, Temperate and boreal forests and woodlands, Mediterranean forests, woodlands and scrub, Tundra and High Mountain habitats, Tropical and subtropical savannas and grasslands, Temperate Grasslands, Deserts and xeric shrublands, Wetlands - peatlands, mires, bogs, Urban/Semi-urban, Cultivated areas (incl.

Units of analysis result from subdividing the Earth's surface into units solely for the purposes of analysis. The terrestrial and aquatic units of analysis serve as a framework for comparison within and across IPBES assessments and represent a pragmatic solution. The terrestrial and aquatic units of analysis used by IPBES are not intended to be prescriptive for purposes other than those of IPBES assessments. They are likely to evolve as the work of IPBES develops.

Any situation in which the current state of knowledge is such that: (i). the order or nature of things is unknown; (ii). the consequences, extent, or magnitude of circumstances, conditions, or events is unpredictable; and (iii). credible probabilities to possible outcomes cannot be assigned. Uncertainty can result from lack of information or from disagreement about what is known or even knowable. Uncertainty can be represented by quantitative measures (e.g. a range of values calculated by various models) or by qualitative statements (e.g. reflecting the judgment of a team of experts).
