People save a glacier – level 2
Swedish scientists did an experiment on the Helags Glacier in the north of the country.
The scientists put a special cloth on the top of the glacier during the summer months. The cloth was made of very strong and durable material which blocked the sun and UV radiation. It also kept the glacier cold.
The team said that they saved at least 3.5 meters of ice from melting. Glaciers are melting all over the world as a result of warmer temperatures. It is important that more people know about the problem because it will be more serious in the future, and people will have to solve it.
Difficult words: durable (something that lasts for a long time without any damage), UV radiation (some of the energy which comes from the sun), melt (to become soft or change into water).
