This summer we witnessed interview teams at the North Pole wearing short sleeve shirts,due to the warm weather.A study published on Aug 29 revealed more concerning issues in the supposedly coldest area of the world.Zombie ice(僵尸冰) from a massive Greenland ice sheet was confirmed to be melting,which would finally raise global sea levels by at least 10 inches on its own,reported Associated Press(AP).
Zombie ice is the kind of ice that is still attached to thicker areas of ice,but is no longer getting fed by larger glaciers(冰川).Since glaciers are getting less snow to complement the amount of ice melted,once the zombie ice is melted,it cannot be re-formed.
Scientists decided to look at the balance of the ice.In perfect balance,snow in the mountains of Greenland flows down and thickens the sides of glaciers,balancing out what's meeting on the edges,according to AP.Bot in the last few decades,there is less refill and more melting,creating an imbalance.
Study co-author William Colgan at the Geological Survey of Denmark and Greenland told AP that 3.3 percent of Greenland's total ice volume would melt eventually."Hunger"would be a good phrase for what's happening to the ice,Colgan added.
With a great number of natural resources buried under the earth,areas of melted ice revealed treasures that attracted the world's richest men.According to CNN,in early August.jye.ai was a"treasure hunt"in Greenland.Billionaires,including Bill Gates and others,financially backed KoBold Metals,a US-based mineral exploration company,to explore the rare metals under the glaciers in Greenland.The company told CNN that since there were enough minerals.jye.ai power hundreds of millions of electric vehicles,the critical resource is capable of powering the green energy transition.
While investors are taking advantage of global warming,experts express their concerns that the mineral exploration is likely to worsen the local environment,draining(榨干) up the world's resources at a faster rate.

1.Nuclear bombs.That's the go-to answer for incoming space objects like asteroids(小行星) and comets,as far as Hollywood is concerned.Movies like Deep Impact and Armageddon rely on nuclear weapons,delivered by stars like Bruce Willis,to save the world and deliver the drama.
But planetary defense experts say in reality,if astronomers spotted a dangerous incoming space rock,the safest and best answer might be something more subtle,like simply pushing it off course by crashing it with a small spacecraft.
That's just what NASA did on Monday evening,when a spacecraft headed straight into an asteroid called Dimorphous,which is around 7 million miles away and poses no threat to Earth.It's about 525 feel across and orbits another larger asteroid.
In images streamed as the impact neared,the egg-shaped asteroid grew in size from a little spot on screen to have its full rocky surface come quickly into focus before the signal went dead as the craft hit right on target.
Events happened exactly as engineers had planned,they said,with nothing going wrong. "As far as we can tell,our first planetary defense test was a success," said Elena Adams,the mission systems engineer,who added that scientists looked on with "both terror and joy" as the spacecraft neared its final destination.
The impact was the peak of NASA's Double Asteroid Redirection Test (DART) ,a 7-year and more than ﹩300 million effort which launched a space vehicle in November of 2021 to perform humanity's first ever test of planetary defense technology.It will be about two months,scientists said,before they will be able to determine if the impact was enough to drive the asteroid slightly off course,probably shortening its original orbit.
NASA plans to launch an asteroid-hunting space telescope named NEO Surveyor in 2026. "We've tacked lots of space rocks,especially the larger ones that could cause extinction-level events.Thankfully,none currently threaten Earth.But many asteroids the size of Dimorphous haven't yet been discovered,and those could potentially take out a city if they came crashing down." explains Lindley Johnson,NASA's Planetary Defense Officer.
(1)How did scientists know the craft hit the asteroid successfully?
A.The signal from the craft was lost as it hit the target.
B.They recorded the whole process with a telescope.
C.The little spot on the screen suddenly disappeared.
D.They monitored the craft with satellites in space.
(2)What is the purpose of launching the spacecraft?
A.To search for evidence of alien life.
B.To end the asteroid's threat to Earth.
C.To save the world and deliver a drama.
D.To test technology for defending Earth.
(3)What can be inferred about Dimorphous?
A.It is a dangerous incoming space rock.
B.It is an egg-shaped asteroid around Earth.
C.It may orbit the same asteroid after the hit.
D.It is expected to blow up after the impact.
(4)Which statement will Lindley Johnson probably agree with?
A.Asteroids are equally destructive whatever the size.
B.NEO Surveyor is aimed to track smaller asteroids.
C.Larger asteroids will no longer threaten Earth.
D.NASA is responsible for the safety of Earth.發(fā)布:2024/12/11 2:0:1組卷:6引用:4難度:0.5 -
