阅读下面短文，根据其内容写一篇60词左右的内容概要。

In the last few decades, scientists have reached consensus and reported that human beings are causing changes in the Earths climate.

In the last 50 years, gases pumped into the Earth’s atmosphere by the factories and vehicles have been speeding up the process of global warming and affecting our climate, Global warming refers to an average increase in the Earths temperature that, in turn, leads to climate change. If we continue to produce carbon dioxide and other gases in such huge quantities, we are expecting severe consequences. Recent reports have warned that global warming will cause terrible climate changes including more frequent flooding, heat, waves and droughts. Serious disease will spread and industries that rely on nature will be badly affected. Increased temperatures will also cause the polar ice to melt, raising sea levels and flooding many islands and cities. How can we stop these disasters from happening?

Government all over the world should take on the responsibility, but this is no easy task. Some governments express reservations about whether global warming is really caused by human activities. Many people believe that they are simply not prepared to give up the amount of money they make from industry to save the earth.

But why wait around for governments to take action? Experts say that each person plays their part. They suggest making small changes like taking public transport, recycling using low-flow shower heads, and buying light bulbs that use less energy. Even simple things like using recycled paper or switching off the light when you leave a room can help. If we add up all these small changes made by everyone worldwide, they won’t be such small changes. They could be the changes that save our future.

In the past decade the popularity of rock climbing has greatly increased, and so has the number of injuries. It has been estimated that rock climbing is now enjoyed by more than 9 million people in the US each year. Study findings revealed a 65% increase in the number of patients that were treated in US emergency departments for rock climbing-related injuries between 1991 and 2012.

The study, published in the online issue of the American Journal of Preventive Medicine, found that about 40,000 patients were treated in US emergency departments for rock climbing-related injuries between 1991 and 2012. The most common types of rock climbing –related injuries were fractures(骨折) and sprains （扭伤）。The ankle was the most common body part to be injured (40%). Climbers in the study ranged in age from 2 to 74, with an average age of 26. The study also found that women took up a quarter of the injuries.

Falls were the primary reason for injury with over three-quarters of the injuries occurring as the result of a fall. The severity of fall-related injuries had a lot to do with the height of the fall. Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower.

“We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbing-related injury,” explained the study author Lara McKenzie, PhD, director at the Center for Injury Research and Policy at Nationwide Hospital. “This trend, combined with the fact that rock climbers have a higher hospitalization rate than other sports and recreational injuries, demonstrates the need to increase injury prevention efforts for climbers.”

1.Which body part is most likely to get injured for a climber ?

A. The arm　　　　　 B. The knee

C. The ankle　　　　 D. The hand

2.How many women climbers in American got injured while climbing a rock between 1991 and 2012 ？
