The level of carbon dioxide (CO2) in the atmosphere is [know / now] at a record high. An American [weather / weathered] station in Hawaii recorded the new high on the 9th of May. It found CO2 levels were at 400 parts [par / per] million (ppm). The [last / past] time CO2 was at this level was five million years ago. This was when there were [no / non] humans on the Earth. Scientists say the 400ppm level is a [warning / warned] sign. They say we must do more to stop this [numeral / number] getting bigger. However, scientist James Butler said he thought CO2 levels would keep [raising / rising] . He warned: "In eight to nine years, we will probably have [saw / seen] the last CO2 reading under 400ppm.” He told reporters that [even / ever] at the South Pole, CO2 would be above 400ppm.

Carbon dioxide is one of the gases that [creation / create] global warming. Just one CO2 molecule can stay [in / on] the atmosphere for hundreds of years. Pieter Tans, one of the [sciences / scientists] measuring CO2 levels, said human activity is making the Earth [warmer / warming] . He said that, "the [burning / burnt] of coal, oil, and natural gas is driving the [acceleration / engine] ". He pointed out that 300 years ago, CO2 levels were around 280ppm. He [added / attached] that 800,000 years ago, they were at 180ppm. Another scientist, Dr Ralph Keeling, warned that CO2 is warming the Earth [to / of] dangerous levels. He is worried about arctic ice melting, causing sea levels to [rise / raise] . This will put billions of people in danger. He said: “It takes a long time to melt ice, but we’re doing it.
