Japanese researchers found that 70 percent of climate warming from human activities.

A Japanese research team recently published a report that the impact of human activities on the increasing global warming. Over the past decade, the factors leading to the rise in the Earth’s average temperature is about 70 percent comes from human activity.

A Japanese research team recently published a report that the impact of human activities on the increasing global warming. Over the past decade, the factors leading to the rise in the Earth’s average temperature is about 70 percent comes from human activity.

Watanabe, Associate Professor, University of Tokyo research team led by Ya-ho in the new issue – the journal “Nature Climate Change” the report said, in the 1980s, the correlation ratio is about 50%. For now, the trend is constantly strengthened.

The team used computer simulations of climate change on a global scale. They assume that the start date from before the Industrial Revolution, Earth has been no increase in greenhouse gas concentrations. Then, enter the tropical waters of ocean currents cause changes in wind and other mechanical data on history, projected sea temperature variation.

The results show that changes in Pacific sea temperatures and other climatic changes inside, the impact on the average temperature in the 1980s, the share accounted for about 47 percent in the 1990s to 38 percent. Over the past decade in the 21st century, the natural effects of share has shrunk to 27%, while human activities affect the Earth’s average temperature increased to share Qi Cheng.

This shows that, although internal changes in climate have no small impact on global warming, but a growing proportion is low, the impact of human factors, the corresponding increase, and climate “warming caused by human activity could further accelerate . “
