All of a sudden a new study suggests that climate change could wipe out half the planet’s plant and animal species by 2070.
The study points out that, when the temperature is rising by 0.5 degrees Celsius over the world, about half of the world’s species could become locally extinct. If the temperature is expected to rise by 2.9 ° c, up to 95 percent of the species would be locally extinct.
“In a way, it’s a” choose your own adventure,'” as one of the co-authors of the study, John, Whom, it said in a statement. “As long as we stick to the Convention of Paris for the fight against climate change, we could lose fewer than two out of every 10 plant and animal species on the planet by 2070. However, if the person is the cause a greater rise in the temperature, we will be able to lose more than one-third or even one-half of all plant and animal species, and based on our results.”

In the decade that has just ended was, by far, the hottest ever recorded on Earth, covered with the second warmest year ever, by 2019, according to data from NASA and the National Oceanic and Atmospheric Administration. In the decade and had eight of the top 10 hottest years on record. The only other in the top-10 list of 2005, and 1998.
Whose to and the other researchers looked at data from the 538 species in 581 the different parts of the world. The focus is on the plant and animal species that were surveyed in the same place in time, for at least 10 years,” the statement said, adding that 44 per cent of the 538 species have already become extinct in one or more of the sites.
“Surprisingly, extinction occurred at sites with smaller changes in average annual temperatures, with larger increases in the hottest annual temperatures,” the study authors wrote.
“By doing so, the change in the 19 climatic variables for each site, we are able to determine which of the variables is local extinction, and the amount of change in a population can tolerate without going extinct,” study co-author Cristian Román-Palacios added.
“We’ve also estimated how quickly the populations will be able to move on in order to try and escape the soaring temperatures,” Román-Palacios continued. “If we put all of these pieces of information for each and every type, we are able to come up with a detailed estimate of global extinction rates of hundreds of species of plants and animals.”
Other studies have focused on the species to migrate to cooler habitats, to avoid the negative effects of a warmer climate. However, to Whom, and Román-Palacios said that, in most of these types, you will not be able to be fast enough to avoid extinction.

They added that species living in tropical regions had a two-to-four times more likely to go extinct than in the temperate regions of the world.
“This is not a big deal, since the majority of plant and animal species occur in the tropics,” Román-Palacios said.
The study has been published in the scientific journal Proceedings of the National Academy of Sciences.
At the beginning of November, and the Home’s administration began the formal withdrawal from the scene of the Paris Climate Agreement, which was agreed upon by 2015 under the Obama administration. As part of the agreement, nearly 200 countries around the world, including China, have their own goals to curb emissions of heat-trapping gases that cause climate change.
Scholars have largely dismissed the fears about man’s impact on global warming, saying that climate change has been around since the dawn of time. There are also the dangers of a warming planet, it is heavily exaggerated, and the question of the impact of fossil fuels on climate change.
