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.
251 statements marked Debated.

Standing
Concerns Annual Precipitation (mm)
Currently States 2500.000000
2500mm/year is the humid-climate classification threshold used in a Pacific/Caribbean Colombian coastal mangrove distribution study; mangroves as a whole range from semi-arid coasts receiving far less rain to superhumid Pacific sites exceeding 5000mm/year, so this is a representative documented figure, not a global mean.

29C (19C plus the source own stated maximum 10C tolerable fluctuation) is an arithmetic upper bound derived from this source own two stated figures, not a directly reported maximum; the source itself names only the survival floor and the fluctuation tolerance, not a labeled high figure.

Standing
Concerns Annual Precipitation (mm)
Currently States 990.000000
990mm is the source's global LAND+OCEAN average annual precipitation figure; the source does not isolate an ocean-only figure. True oceanic precipitation is understood to run higher than this global blend (ocean evaporation exceeds ocean precipitation, balanced by land) and varies enormously by latitude, from near zero over the subtropical gyres to well over 3000mm under the tropical convergence zone. No single settled ocean-specific figure was found on an accessible source.

Monarch Butterfly, Species
Standing
Concerns Conservation Status
Currently States Endangered
The IUCN assessed the migratory monarch subpopulation as Endangered in 2022, while the species as a whole, including non-migratory populations outside North America, is not separately listed; national assessments in the United States have proposed but not finalized Endangered Species Act protection. This atlas records the migratory population's IUCN status as the honest current answer rather than a single unqualified figure.

Concerns Population Estimate
Currently States 225000000.000000
Monarch numbers are commonly measured by the area of forest their overwintering colonies occupy in Mexico rather than by a direct count of individuals, then converted to a population estimate; the conversion factor itself is debated among researchers, and year-to-year totals have swung by an order of magnitude, so any single figure understates the volatility.
