In a recent study, a team of investigators analyzed oxygen - 18 isotopes (δ18O) from the otoliths — or ear bones — from archeological Pacific cod (dating about 1790 - 1920) to reconstruct nearshore temperature regimes in the Gulf of Alaska. (arcus.org)
Biodiversity would likely collapse impacting food production and other ecosystem services; the Earth would warm to a new temperature regime of destructive extremes; and vanishing natural resources would likely spawn human conflict. (news.mongabay.com)
An entirely new temperature regime could impair the species» ability to return as it has after past beetle outbreaks. (scientificamerican.com)
