Study of plant looming dangers of global warming

Research has shown in the United States since the days that the plants bloom faster than scientists expected response to climate change, which could have a devastating impact indirectly on food chains and ecosystems.

Scientists say that global warming will have a significant impact on hundreds of plant and animal species around the world, changing some of the patterns of education, immigration and nutrition.

May affect the increased concentration of carbon dioxide in the atmosphere from burning fossil fuels to produce plants for oxygen, while the high temperatures and rainfall patterns may change its behavior.

Researchers at  California University at San Diego and several other U.S. institutions, "predicted species response to climate change is a major challenge in ecology".

They said the plants were the focus of the study because their response to climate change may affect the food chain and ecosystem functions such as immunization and nutrition courses and water supply.

The study is based on published on the Internet site Nature (Nature) on the evidence from studies on the life cycle of plants and experiments in four continents, including 1634 species. The experiments revealed that some of the reduced speed estimate budding by 8.5 times and the growth of the papers by 4 times.

The study "in all experiments the amount of species expected lower growth - in the leaves and flowers - the result of rising temperatures."

She added that the experiments in the future may need to be improved in order to better predict how plants will respond to climate change.

And plants are essential for life on earth. They are the base of the food chain, as used photosynthesis to produce sugar from carbon dioxide and water. And release oxygen that you need almost all the organisms that live on the planet.

Scientists estimate that global temperature rose about 0.8 degrees Celsius since 1900 and about 0.2 degree per decade since 1979.

So far no efforts to reduce greenhouse gas emissions enough to prevent global warming for more than two degrees Celsius this century, a point that scientists say expose us to the risk of climate is stable common where climate variability severe, leading to droughts, floods and crop failures and rising sea levels.
