ALL COUNTRIES SHOULD REDUCE GREENHOUSE EMISSIONS.



Without the greenhouse effect the Earth would not be warm enough for humans to live, but if it becomes even a little warmer there will be major problems. The greenhouse effect is the rise in temperature the Earth experiences because certain gases in the atmosphere (water vapour, carbon dioxide, nitrous and methane, for example) trap energy from the sun, forming greenhouse-like layer.

Average global temperatures have increased by 1 degree F over the past century. Scientist expect the average global temperature to increase an additional 2-6 degree F over the next 100 years. This may not sound like much, but at the peak of the last ice age (18000 years ago)
the temperature was only 7 degrees colder than it is today, and glaziers covered much of North America!

It is important to reduce greenhouse emissions because when the climate changes, there may be big changes in the things that people depen...
