Climate change has been blamed for killer hurricanes, sea level rise, and drought, but a new report suggests the effects of climate change might hit the world's coffee supply. Up to 70 percent of the world's coffee supply could be threatened over the next 66 years, according to a new study by researchers at England's Royal Botanic Gardens.
Nearly 100 percent of the world's Arabica coffee growing regions could become unsuitable for the plant by 2080, according to the study. Beans from Arabica coffee plants account for about 70 percent of the world's coffee, but the plant also has to be grown under strict weather conditions: they grow well at temperatures between 64 and 70 degrees Celsius, and are highly influenced by frost or temperatures higher than 73 degrees Celsius.
With temperatures estimated to increase by between 1. 8 and 4 degrees Celsius by the end of the century, the fragile plant might become increasingly expensive and difficult to grow, especially in places such as Ethiopia and Kenya. In that worst case, nearly all of the world's native Arabica coffee would die out. Under more conservative(保守的)estimates, about 65 percent of the regions used to grow the coffee would become unsuitable for it. The evidence from coffee farmers and coffee growing regions around the world is that they are already suffering from the influences of increased warming.
Some farmers would likely be able to move their operations to other areas or would be able to overcome climate change with artificial cooling techniques, but wild Arabica is generally considered to be much more suitable for making high-quality coffee.
If Arabica becomes impossible to raise in its native areas, it could do serious damage to the economies of the mainly third-world countries in which it grows. Coffee is the world's most popular drink and is the second most-traded product in the world, behind oil.
The virtual choir was the idea of award-winning composer and conductor Eric Whitacre. Born in the USA on 2 January 1970, Whitacre (begin) studying music at the University of Nevada in 1988. He fell in love with Mozart's classical music when he sang for the university choir. (move) by the music, he said, "It was like seeing color for the first time." He graduated from university in 1995, and then received a master's degree in musical composition from the Juilliard School in New York in 1997. over the next 10 years, Whitacre's original compositions began to become quite popular among choirs singers.

From the age of five, I was constantly surrounded by fear. It started when I was sent to boarding school. I used to 1 the bed and, the first night it happened, I knocked on the nuns' (修女) door to ask for 2. Instead, they made me do the walk of 3, carrying a packet of wet sheets through all the 4 as they announced, 'Make way for the bed - wetter,' and 5 the children to laugh and shout horrible things. That happened 6.
I grew into a problem 7 and spent much time in bars drinking to forget the hopelessness and 8. That's where I met my first husband, who turned out to be a 9 man. It was only when he 10 me into a state of unconsciousness that things changed. I knew I couldn't go back - if I did, I would 11. So I decided to remove the layers of pain and cruelty and 12 them with happiness and success. I started to read books about how to think highly of yourself. I got into 13 and won competitions, I realised, 'I am not a 14 person like the nuns and my husband told me.' I decided to take the 15 I used in sport - my determination to keep 16 - and apply them to everything in my life. That's when I 17 I was a really good business person.
Whatever your past has been, don't 18 it for who you are today. Thy and find something 19 in it. That's the only possible way to 20 those things, be brave and turn everything around.
An experimental cleanup device called RemoveDEBRIS has successfully cast a net around a dummy (仿真的) satellite, imitating a technique that could one day collect spaceborne garbage.
The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it symbolizes an early step toward solving what has already been a critical issue: junk in space.
Millions of pieces of junk are turning around in orbit the result of 50 years of space travel and few regulations to keep space clean. At orbital speeds, even a small bit of paint crashing with a satellite can cause critical damage.
Various companies have plans to send thousands of new satellites into low-Earth orbit, already the most crowded area.
The RemoveDEBRIS experiment is run by a company and researchers led by the U. K.'s Surrey Space Center and includes Airbus, Airbus-owned Surrey Satellite Technology Ltd. and France's ArianeGroup.
Guglielmo Aglietti, the director of Surrey Space Center, said that an operational version of the RemoveDEBRlS technology would cast a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large pieces of junk, including dead satellites up to 10 meters long.
The RemoveDEBRIS satellite will conduct a few more experiments in the coming months, including testing navigation features that could help guide the satellite to a specific piece of debris.
Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, said the success of this week's experiment was exciting, but he cautioned against "over- publicizing" it.
There are still enormous barriers to clear before operational cleanup tasks are underway, he said, and the most discouraging is figuring out how to fund such projects.
Aglietti, the Surrey professor who helped lead the RemoveDEBRIS project, said "The challenge will lie in persuading the relevant authorities to sponsor these tasks." Aglietti said he hopes RemoveDEBRIS will conduct a few cleanup tasks per year, targeting the largest pieces of junk in the most crowded orbits.
