The report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of all the Earth's species with extinction even in the absence of the other four factors, while if the warming reached 4.3 °C (7.7 °F), 16% of the Earth's species would be threatened with extinction.
This article is a list of biological species, subspecies, and evolutionary significant units that are known to have become extinct during the Holocene, the current geologic epoch, ordered by their known or approximate date of disappearance from oldest to most recent.
Jamaica; possibly Dominica, Guadeloupe, and Bahamas Last recorded with certainty in 1880. An unconfirmed sighting was made west of Bimini, Bahamas in 1936. It was hunted with dogs in its only known breeding site, the Blue Mountains of Jamaica. [32] The extinct status is hard to ascertain as it is a nocturnal and dark-colored sea bird. [39]
Most likely underwater volcanism associated with the Caribbean large igneous province, which would have caused global warming and acidic oceans [14] Aptian extinction: 117 Ma: Unknown, but may be due to volcanism of the Rajmahal Traps [15] Jurassic: End-Jurassic (Tithonian) 145 Ma
The genus Orcinus was published by Leopold Fitzinger in 1860, [4] its type species is the orca named by Linnaeus in 1758 as Delphinus orca.Taxonomic arrangements of delphinids published by workers before and after Fitzinger, such as John Edward Gray as Orca in 1846 and Orca (Gladiator) in 1870, are recognized as synonyms of Orcinus.
A 2018 study published in Science found that global orca populations are poised to dramatically decline due such toxic pollution. [ 163 ] [ 164 ] In the Pacific Northwest , wild salmon stocks, a main resident food source, have declined dramatically in recent years. [ 3 ]
A pair of orcas working in concert have been killing great whites along a stretch of South African coastline since at least 2017, plundering the sharks’ nutrient-rich livers and discarding the rest.
