However, the speed of recent climate change is very fast. Due to this rapid change, for example cold-blooded animals (a category which includes amphibians, reptiles and all invertebrates) may struggle to find a suitable habitat within 50 km of their current location at the end of this century (for a mid-range scenario of future global warming).

Habitat loss, disease and climate change are thought to be responsible for the drastic decline in populations in recent years. [ 12 ] Declines have been particularly intense in the western United States , Central America , South America , eastern Australia and Fiji (although cases of amphibian extinctions have appeared worldwide).
Specific reasons for the decline may include climate change, chytridiomycosis, or volcanic activity, but the main threat is habitat destruction as logging, agricultural activities, and human settlement reduce their often tiny, fragmented ranges. Survey work is being undertaken to assess the status of these salamanders, and to better understand ...
Scientists have determined that a giant salamander previously housed at the London Zoo not only represents a newly discovered species — it's also likely the largest amphibian known to man.
Like most woodland salamanders, the Shenandoah salamander eats mites, flies, small beetles, springtails, and other soil invertebrates. [9] No direct observation of predation of the Shenandoah salamander has ever been reported, but potential predators residing within the habitat of the Shenandoah salamander include ring-necked snakes, short-tailed shrews, brown thrashers, and towhees.

Alpine salamanders are not resilient to habitat changes— few terrestrial salamanders are— so risks of climate change altering their living spaces is severe. [23] Although alpine salamanders are listed as Least Concern on IUCN Red List, their numbers are decreasing. [1] Additionally, some subspecies of S. atra are in greater danger. [25]
The hellbender (Cryptobranchus alleganiensis), also known as the hellbender salamander, is a species of aquatic giant salamander endemic to the eastern and central United States. It is the largest salamander in North America. A member of the family Cryptobranchidae, the hellbender is the only extant member of the genus Cryptobranchus.
In 2020, a study in Nature Climate Change estimated the effects of Arctic sea ice decline on polar bear populations (which rely on the sea ice to hunt seals) under two climate change scenarios. Under high greenhouse gas emissions, at most a few high-Arctic populations will remain by 2100: under more moderate scenario, the species will survive ...
