Climate change will endanger nearly one in three species by 2100, studies show

Changing of the climate exacerbates global extinction crisis, new study warns.

A research group led by the University of Minnesotanearly one in three — 30 percent — of all species discovered will be extinct or endangered by 2100.

This is mainly due to the loss of biodiversity as a result of production and consumption, population and climate change.

Noah Greenwald, director of endangered species at the nonprofit Center for Biological Diversity, called the numbers “quite alarming.”

“It took many years for climate change to become a major issue for households,” Greenwald said. Bulletin of the Union.

“The extinction crisis is actually part and parcel of the same scale and severity as climate change.”

A new study warns that climate change is exacerbating the global extinction crisis. A research team led by the University of Minnesota found that by 2100, nearly one in three – 30 percent – of all species will be extinct or endangered.

The team conducted the survey, inviting input from experts from around the world, and received 3,331 responses from biodiversity scientists in 187 countries, covering all major species groups, habitats and ecosystems.

Most species include plants and insects, as well as other invertebrates, but so little is known about these creatures that experts “cannot determine the extent to which they are threatened,” said Healy Hamilton, chief scientist at nonprofit research group NatureServe. Bulletin of the Union.

However, these species are known to play a key role in purifying the air, filtering water, and ensuring the health of the Earth’s soil.

This study is one of the first to collect input from thousands of international biodiversity experts who provided geographic and demographic data.

The survey also showed that at least one million species of animals and plants are currently on the verge of extinction, and 10 percent of them are insects.

“Global biodiversity loss and its impacts may be greater than previously thought due to higher estimates provided for understudied taxa and underrepresented experts,” says a study published in the journal. The boundaries of ecology and the environment.

The team obtained an “overwhelming consensus” that climate change and overexploitation are among the top causes of biodiversity loss.

The results show that estimates of past biodiversity loss have been highest among those who study freshwater ecosystems, and many tropical habitats are estimated to have the highest percentage of species threatened or extinct since 1500.

The survey also showed that at least one million species of animals and plants are currently on the verge of extinction, and 10 percent of them are insects.

“Our survey estimates, which were provided by 629 experts studying terrestrial and freshwater invertebrates, suggest that the percentage of threatened insect species may be much higher,” the team shared in the study.

“Further research on the diversity and threatened status of insects and other superdiverse and understudied taxa is urgently needed, especially in light of significant recent insect declines in some locations.”

“If current trends continue, further biodiversity loss is expected and experts estimate that 37% (uncertainty range: 20-50%) of species could be threatened or extinct by 2100,” the study says.

In addition, it has been predicted that many endangered species will become extinct before the end of this century.

“Most experts (84%) expected species to become extinct in less than 100 years after being threatened, with 75% of experts expecting extinction to occur within decades (10–100 years) and another 9% of experts extinction is expected to occur within 10 years. years.’

The researchers encourage biodiversity experts to use these results to learn how their own perspectives differ from those of other experts and to ensure that a range of perspectives are taken into account when conducting global biodiversity assessments, setting global biodiversity goals and targets, and developing a new politicians. and other transformative changes needed to conserve biodiversity.

Akira Mori of the University of Tokyo in Japan said in a statement: “Because biodiversity is highly regional, our study’s attempt to bring together the views of regional experts from around the world is unprecedented.

“In terms of social and cultural diversity and inclusiveness, even if they are not necessarily complete, I believe that we have presented certain proposals for future discussions on international politics.”

DISAPPEARING SPECIES: EXPERTS PREDICTION GLOBAL WARMING WILL REDUCE CREATURES

A recent study in Canada showed that beetle numbers have declined in this region over the last century.

After studying eight beetle species and measuring animals from the past and present, they found that some beetles have adapted to shrinking body size.

The data also showed that larger beetles were shrinking in size, while smaller ones were not.

About 50 million years ago, the Earth warmed by three degrees Celsius (5.4 °F), and as a result, the number of animal species at that time decreased by 14 percent.

Another warming event around 55 million years ago called the Paleocene-Eocene Thermal Maximum (PETM) warmed the earth up to eight degrees Celsius (14.4 °F).

In this case, the animal species of that time were reduced by a third.

Woolly mammoths have fallen prey to a warming climate, reduced habitat and increased hunting by a growing population of early humans, leading to their extinction - along with many large animals.

Decreasing body size is seen from several global warming events.

Global temperatures are expected to continue rising and the average size of most animals will decrease.

In addition to global warming, there has been a sharp decline in the number of large animals in the world.

The so-called “megafauna” are endangered large animals. With long lifespans and relatively small populations, they are less able to adapt to rapid change than smaller animals that breed more frequently.

Large animals such as mastadon, mammoths and the western black rhinoceros, which were declared extinct in 2011 and are often hunted for trophies or food, have become extinct.
