New research shows that a wide variety of plants and animals are likely to become less common, if do not do something to avoid the worst effects of climate warming.
According to the "business as usual" scenario, there is no significant reduction in greenhouse gas emissions, one-third of the approximately 50% of the plants and animals could disappear, they are now found by half in 2080, Rachel Warren said researchers at the University of East Anglia in England. These losses may lead to the extinction of native species.
In the study, published online today (May 12) in "Nature" magazine on climate change, researchers at the global warming may affect the world's 50,000 different species. The study used a computer model to calculate the required climatic zones, these plant and animal life, and the analysis of these areas and organisms accompanying range, it is possible in the next shift, Warren told OurAmazingPlanet.

In many cases, these changes are likely to lead to the extinction of animals and plants due to global warming, to move beyond the point, they can not go, such as the top of the hill, toward the shoreline of the ocean, Warren said.
However, the limited range of plants and animals are deliberately excluded the objective of this study is to assess the impact of climate change, common species, because, Warren said. In other words, if you total extinction - This study did not - the Global Biodiversity impacts of climate change look worse.
Not too late
This is not too late to do something to prevent widespread loss of species, however. The study found that if the slowdown in emissions, and eventually begin to reduce, by 2017, about 60% of the losses can be avoided, "Warren said. Peak emissions in 2030, and to reduce the loss of about 40% can be avoided.
The loss may be Central and South America, Australia, North Africa and Southeast Asia is particularly serious, "Warren said. These areas are vulnerable to rainfall and temperature rise and fall according to the study.
She added that the decline in plants and animals decline means the services provided by these microorganisms, such as recycling of nutrients, purify the air and water, pollination, and the use of eco-tourism and leisure.
Some species may be more tolerant than others, but the point of this study is that it does not focus on any kind of plant or animal, or specific high-profile organisms, such as polar bears, Warren said. "I want to express the most important news is that there are a large proportion of species," she said.
Warren said she believed that a conservative estimate because the study did not take into account the interactions between animals and plants, which may exacerbate the fall, if the preferred food plants of the animal disappeared, it can bite the dust. The study also did not consider extreme weather and global warming, there are many models of the project will get worse, she said.
"There will be winners and losers species in the natural world to address climate change," said Hannah Lee, Conservation International, the study's senior researcher who was not involved in the biology of climate change. "This study shows that we can greatly reduce the losers common, well-known species to take measures to reduce climate change."
"Amazing," "scared me," said Terry, who was not involved in the study of Stanford University scientists root. "It shows that the number of species, we are actually the influence of carbon dioxide in the atmosphere," she told OurAmazingPlanet.
