Scientists have known about the greenhouse effect since 1824, when Joseph Fourier calculated that the Earth would be much colder if it had no atmosphere.
The rapid rise in greenhouse gases is a problem because it is changing the climate faster than some living things may be able to adapt.
Also, a new and more unpredictable climate poses unique challenges to all life.
As the mercury rises, the climate can change in unexpected ways.
In addition to sea levels rising, weather can become more extreme.
My Favourite Profession I think that the most unusual job is an astronaut. It's so fantastic to float in the air at work. I think it is an amazing experience to look upon the Earth from millions kilometers away from our planet. An astronaut pilots a space shuttle into space and works on a special part of a mission! He or she works long hours. An astronaut works as part of a crew and therefore has specific responsibilities aboard the space station. He or she has a lot of chores aboard. Surely, it's very dangerous to be an astronaut. An astronaut risks his/her life on a mission. But it would be a great experience to visit Mars!
