Thank you for joining us for today's Spotlight program. I'm Joshua Leo.
And I'm Rebekah Schipper. Spotlight uses a special English method of broadcasting.
It is easier for people to understand, no matter where in the world they live.
In 2005, scientists with NASA, the United States space program, took a picture of the earth from space.
What they saw shocked them.
The picture showed that the Arctic's thick ice is shrinking.
You see, the scientist compared their picture with another picture taken in 2004.
It was very clear that there was less ice in 2005.
In fact, in just one year, 730,000 square kilometres of the Arctic's thick ice melted.
Dr. Nghiem is one scientist who studied the pictures.
"…The change we see between 2004 and 2005 is enormous.
What we have here is 14 percent loss in one year.
This is 18 times greater than the previous rate."
Scientists have reason to believe that the earth's temperature is rising.
They have studied many affects of warmer weather.
This is the third and last program in a series about the physical signs of global warming.
People all over the world are seeing evidence of climate change.
Take a look around. Do you see any of these signs where you live?
Today's sign: Climate Refugees.
