Rising temperatures increase biodiversity on Earth
Research may indicate that climate change is leading to the gradual extinction of some species, but in the long run global warming is leading to species proliferation and biodiversity enrichment, according to a new British scientific study.
Researchers from the Universities of York, Leeds and Glasgow, led by evolutionary biologist Peter Meiju, published the study in a review of the US National Academy of Sciences (PNAS) survey, according to GeoScience and Nature. data reaching up to 540 million years ago. The researchers – to their great surprise, as they say – found a direct proportional relationship between heat and biodiversity: when the former increased, so did the second, and when the former receded, the latter declined.
The study thus concluded that previous warm climates on Earth were accompanied by increasing species extinction, but at the same time promoted the creation of new species, eventually increasing biodiversity in the long run. Based on this reasoning, British scientists suspect that the current trend of rising temperatures will cause the loss of several species, but over time – something that cannot be understood now – the global biosphere will eventually be enriched by climate change.
Scientists have for years observed that the abundance of species is increasing as one approaches the hottest Ecuador. The new study argues that the same trend – the ratio between heat and biodiversity – applies not only to space, but also over time. Of course, as biology professor Tim Benton pointed out, “this does not mean that the current global warming is good for existing species. Increases in global biodiversity take millions of years and in the meantime it is to be expected that several species extinctions will occur.“
According to Meihiu, the different rhythm of the two changes plays a decisive role, as the evolution of new species from the preceding ones takes thousands or even millions of years, that is, much slower than the extinctions of species already observed due to climate change.
