Scientists already know for sure what will happen in the future.
Compare your predictions about the future with the experts’
predictions. Were your guesses it right?
One important change in the future will be the temperature.
Scientists say that by 2050 the planet will have a temperature
increase of 3 to 4º C. It seems like nothing, but it will have
enormous effects in the ecosystems. Researchers analyzed
greenhouse gas emissions and not even the most optimistic
scientists’ formulas result in such a low percentage.
By 2050, the sea level will be 25 centimeters higher. With higher
temperatures, the defrosting process in Antarctica will become twice as fast. The glaciers are going to
melt. This will result in an increasement in the sea level. Scientists’ calculations say it will increase 50
cm by 2100. Another consequence will be the floods. The likelihood of flooding in coastal towns will
rise more than nine times. The economic losses will be greater than 50 billion dollars.
The growth of the Himalayas will be another change. In 2050 the highest mountain range is going to
be 165 millimeters higher due to the movement of the Indian plate below it. The nearby towns are
worried about the possibility of earthquakes in the area.
Eating fruits and vegetables is going to be difficult. There won’t be enough crops to meet world
demand. There will be serious consequences for species such as birds. Scientists say that in 2050, 99%
of seabirds will have eaten plastics.
