11月18日CNN聽力：奧巴馬反對美加輸油管道項目 NASA或將頒布關於火星龐大發明
For seven years and most of Barack Obama'spresidency, there's been a lot of back and forth oversomething called the Keystone XL Pipeline.
It would have been an oil pipeline carrying morethan 800,000 barrels of petroleum every day fromCanada to oil refineries in the U.S. gulf coast.
But President Obama announced on Friday that itwon't be built, unless not under his watch.
Republicans spoke out against the decision, saying it prevents thousands of jobs from beingcreated and eliminates a boost to the U.S. economy.
Democrats support the decision, saying it won't create many permanent jobs and that itcould hurt the environment.
They see oil as a dirty fuel.
The U.S. State Department doesn't think the pipeline would have been bad for theenvironment.
But the president named the climate as part of the reason for his decision.
President Obama rejected the Keystone pipeline, saying the Canadian project would have sentthe wrong message to the world on the issue of climate change.
The president accepted the recommendation of Secretary of State John Kerry whosedepartment analyzed the project for nearly seven years.
Mr.Obama acknowledged Keystone had become embroiled in politics as Republicans said theproject would have created U.S. jobs.
While Democrats argued an approval from the White House would have been a damagingdefeat in the battle against global warming.
In the past, the president had said he would turn down the pipeline if it could contributeclimate change,something his own State Department concluded would not occur.
Not surprisingly, though, the president sided with his own party.
Here's what he had to say.
America's now a global leader when it comes to taking serious action to fight climate change.
And, frankly, approving this project would have undercut that global leadership.
And that's the biggest risk we face—not acting.
The president will now take that message to the upcoming global climate summit in Paris in afew weeks.
White House officials say it would have been very difficult for President Obama to go to thatsummit having approved the Keystone Pipeline project.
Both the company behind Keystone, TransCanada, and the Canadian government, expresseddisappointment in the president's decision.

Some of our viewers in Southern California saw it on Saturday night, a bright white lightstreaming across the sky.
Some folks alerted police.
Others speculated it was a meteor or aliens.
Nope. The U.S. Navy says it was testing out a missile.
According to the military, it had been planned in advance.
It was a test missile flight launched from a submarine named the USS Kentucky.
The weapon itself was not armed, so it couldn't blow up even if it had hit something.
Los Angeles International Airport was aware of the test and says it will be keeping flights awayfrom the area until Thursday when these military tests wrap up.
My old school dream job would have been town crier.
It'd start up every "Roll Call" saying, "Hear ye, hear ye".

At the moment, it's not possible to get someone to Mars and back alive.
One of NASA's five active missions called MAVEN involves a satellite orbiting Mars that tookmore than ten months to get there from earth.
Still, because NASA hopes to put someone on Mars one day, they're getting all the informationthey can from MAVEN and its $672 million mission.
Thanks to the space probe MAVEN, we now have clues in the mystery of Mars' shift from awarmer, wetter environment to the cold, dry desert it is today.
MAVEN has been exploring Mars' atmosphere since 2014.
One of its main goals is to figure out how and why it got so thin.
This low high pressure atmosphere is comprised mostly of carbon dioxide will prevent freshwater from being present, because it will boil at 10 degrees Celsius or 50 degrees Fahrenheit.
On Earth, it boils at 212 degrees Fahrenheit.
