Nature Atlas
Claims this atlas currently marks as unsettled or as tested and found false. A debated fact is one scholars hold competing positions on; a debunked one has been checked against the record and found not to hold. Both are kept in view rather than quietly smoothed over, with the reasoning that put each one where it stands.

Coast Redwood, Conservation StatusEndangered
Coast Redwood, Species
Standing
Concerns Conservation Status
Currently States Endangered
IUCN Red List assessment by Farjon and Schmid, 2013, listed coast redwood as Endangered under Red List criterion A2 (population decline). A 2017 US Forest Service report by Erin Clover Kelly argues the listing is methodologically flawed for a species like redwood and misidentifies the real conservation concern, which is old-growth ecosystem functionality rather than the survival of individual trees; see the dissent on this fact.

Cold Seep, Typical Low Temperature (C)1.000000
Cold Seep, Biomes
Standing
Concerns Typical Low Temperature (C)
Currently States 1.000000
1C is derived by applying this source own stated approximately 3C additional cooling below 1000m depth to the 4C deep-ocean average carried on this entity own temperature-high-c fact. The source states a relative offset rather than an absolute figure, so the result is recorded as debated rather than precisely attested.

Cold Seep, Annual Precipitation (mm)0.000000
Cold Seep, Biomes
Standing
Concerns Annual Precipitation (mm)
Currently States 0.000000
Cold seep communities sit on the deep ocean floor, the same depth band as this pass's other deep-sea biome entities, with no atmospheric contact. The surface-blended precipitation figure used on the Marine, Open Ocean, Neritic Zone and Coral Reef biome entities does not meaningfully apply to a seafloor seep, so 0mm is recorded as the physically honest figure rather than forcing an inapplicable surface figure.

Common Cuckoo, Species
Standing
Concerns Population Estimate
Currently States 25000000.000000
Published global estimate ranges from 25 million to 100 million individuals; the lower, more conservative figure is recorded here rather than a false precise midpoint, matching this atlas's existing convention for wide-range population estimates (compare Arctic Tern, Gray Wolf).
