Scientists have found that a third of the world's animals could disappear after 50 years

The anthropogenic factor has an enormous impact on the environment. Today, researchers around the world agree that rapid climate change is caused by human activity. As you know, the problem is the temperature rise. Today, a third of all plant and animal species are threatened with extinction. The results of a study published in the National Academy of Sciences' Proceedings magazine show that there will be no rhinos, zebras, elephants, lions and many other animals on Earth in just 50 years. If climate change continues at the same rate, the situation may worsen over time.

A study of humanity's impact on ecosystems around the world examined recent extinctions from climate change and various predictions of climate models. According to the study's authors, their work is probably the first of its kind. The fact is that it has been designed to assess large-scale models of the climate crisis extinction, using data from recent extinction and the rate of species development. So far, however, this work is the latest in a series of scientific studies on the sixth mass extinction of wild animals.

Past extinction data helps predict new disasters

A research team from the University of Arizona used data on 538 species at 581 locations around the world, focusing on species that were examined at the same location at least 10 years apart. They found that 44% of 538 species had already died out in one or more places where they previously lived. They also generated climate data through measurements taken during the earliest survey of each site and in later studies.

According to The Independent, by analyzing the change in 19 climate variables at each site, scientists were able to determine which variables contribute to local extinction and how many changes the species can make before it dies out. In addition, the researchers also assessed how quickly these or those species can move to avoid rapid environmental changes and temperature rises. The further goal of the researchers is to bring together all information for each species. Then scientists can provide detailed estimates of global extinction rates for hundreds of plant and animal species.

The results of the study showed that most species cannot move quickly to other regions to avoid extinction. The researchers came to this conclusion based on previous species velocities. Instead, many ways can learn to withstand a slight increase in maximum temperature, but only to a certain extent. About 50% of the species fell victim to local extinction when the maximum temperature rose more than 0.5 ° C, and 95% died out when the temperature rose more than 2.9 ° C.

In one way or another, predictions of species extinction depend on how much warmer the local climate will be in the future. If the world's leaders comply with the Paris Agreement, less than two out of ten plant and animal species will be lost on Earth by 2070. However, if temperatures continue to rise, the losses can be more than a third or even half of all animal and plant species.
