A 2020 long-term study of more than 60 bee species published in the journal Science found that climate change causes drastic declines in the population and diversity of bumblebees across the two continents studied, independent of land use change and at rates "consistent with a mass extinction."
Furthermore, climate change may cause ecological disruption among interacting species, via changes in behaviour and phenology, or via climate niche mismatch. [9] For example, climate change can cause species to move in different directions, potentially disrupting their interactions with each other. [10] [11]
Habitat destruction through natural processes such as volcanism, fire, and climate change is well documented in the fossil record. [2] One study shows that habitat fragmentation of tropical rainforests in Euramerica 300 million years ago led to a great loss of amphibian diversity, but simultaneously the drier climate spurred on a burst of ...
Climate change has the potential to exacerbate all of these processes. Nehring (1999) found a total of 16 non-indigenous thermophilic phytoplankton established in habitats northwards of their normal range in the North Sea. He likened these changes in range of more southerly phytoplankton to climatic shifts in ocean temperature.
It is likely there will be a 15% decrease in the number of marine animals and a decrease of 21% to 24% in fisheries catches by the end of the 21st century because of climate change. [ 68 ] A 2020 study reports that by 2050 global warming could be spreading in the deep ocean seven times faster than it is now, even if emissions of greenhouse ...
Simply put, the professor stated that animals must either “move, change, or die.” Perhaps L. C. Megginson said this best when he paraphrased Charles Darwin and noted that, “It is not the ...
Climate change is likely to favour some invasive species and harm others, [161] but few authors have identified specific consequences of climate change for invasive species. [ 162 ] Invasive species and other disturbances have become more common in forests in the last several decades.
Deforestation causes many threats to wildlife as it not only causes habitat destruction for the many animals that survive in forests, as more than 80% of the world's species live in forests but also leads to further climate change. [8] Deforestation is a main concern in the tropical forests of the world.
