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 ...
Kaiho's follow-up paper estimated that under what he considered the most likely scenario of climate change, with 3 °C (5.4 °F) of warming by 2100 and 3.8 °C (6.8 °F) by 2500 (based on the average of Representative Concentration Pathways 4.5 and 6.0), would result in 8% marine species extinctions, 16–20% terrestrial animal species ...
[109] [110] A 2013 study found that 47–73 coral species (6–9%) are vulnerable to climate change while already threatened with extinction according to the IUCN Red List, and 74–174 (9–22%) coral species were not vulnerable to extinction at the time of publication, but could be threatened under continued climate change, making them a ...
In the study, scientists applied climate models simulating temperature, wind, rain and humidity trends for Pangea Ultima expected to form in the next 250 million years.
A male humpback whale made one of the longest and most unusual migrations on record for the species, an anomaly scientists say might be linked to climate change. The whale was first sighted in ...
Mammal species, for example, typically persist for 1 million years. Biodiversity has grown and shrunk in earth's past due to (presumably) abiotic factors such as extinction events caused by geologically rapid changes in climate. Climate change 299 million years ago was one such event. A cooling and drying resulted in catastrophic rainforest ...
Marine Animals: These species' average lifespan is 4–5 million years. Reasons why marine animals go extinct include interactions with fisheries, capturing, pollution, habitat degradation, climate change, and overharvesting. Mammals: These species' average lifespan is 1 million years. Habitat loss is the leading reason for why mammals go extinct.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
