Carbon dioxide at record high level

The level of carbon dioxide (CO2) in the (1) ____________ is now at a record high. An American weather (2) ____________ in Hawaii recorded the new high on the 9th of May. It found CO2 levels were at 400 parts per million (ppm). The (3) ____________ time CO2 was at this level was five million years ago. This was when there were no (4) ____________ on the Earth. Scientists say the 400ppm level is a warning (5) ____________. They say we must do more to stop this number (6) ____________ bigger. However, scientist James Butler said he thought CO2 levels would keep (7) ____________. He warned: “In eight to nine years, we will probably have seen the last CO2 reading (8) ____________ 400ppm.” He told reporters that even at the South Pole, CO2 would be above 400ppm.

Carbon dioxide is one of the (9) ____________ that create global warming. Just one CO2 molecule can (10) ____________ in the atmosphere for hundreds of years. Pieter Tans, one of the scientists measuring CO2 levels, said human (11) ____________ is making the Earth warmer. He said that, “the (12) ____________ of coal, oil, and natural gas is driving the acceleration”. He (13) ____________ out that 300 years ago, CO2 levels were around 280ppm. He added that 800,000 years ago, they were at 180ppm. Another scientist, Dr Ralph Keeling, (14) ____________ that CO2 is warming the Earth to dangerous levels. He is worried about arctic ice melting, causing  (15) ____________ levels to rise. This will put billions of people in danger. He said: “It takes a long time to (16) ____________ ice, but we’re doing it. It’s scary.”
