She says, “We can’t predict the climate well enough to know 4 to expect, but it could be very serious.” Others who agree with her think there may be 5 rise of several metres in the sea level, or predict severe storms, floods, droughts, famines, the 6 of diseases and the disappearances of 7 . On the other hand, there are those, like George Hambley, who are 8 to this view and believe that we should not worry about high levels of carbon dioxide in the air. They predict that any warming will be mild with few bad environmental 9 . In fact, Hambley states, “More carbon dioxide is actually a positive thing. It will make plants grow quicker; crops will produce more; it will 10 a greater range of animals, all of which will make life for human beings better.”
