Large Storms Affecting Caribbean, US

Everyone is talking about Harvey, Irma, Jose and Katia.

They are the names of very large storms, affecting the area around the Caribbean*, Mexico and the southern United States.

Hurricanes are given names, like “Irma” to make it easier to refer to them.

People in these areas are used to dealing with storms. But these storms are much larger than normal. They have very high winds—up to 120 kilometres an hour—with lots of rain that can flood people’s houses and force them to leave the area. (In this case, leaving your home is known as “evacuating.”) In Florida, more than 6.4 million people have been told to evacuate before Irma gets there, according to a report from CBC News.

Scientists Working To Save Arctic Ice Cap

A team of scientists has come up with a plan they say could help rebuild the Arctic ice cap. The ice cap is a huge area of sea ice that covers most of the Arctic Ocean all year round.
Usually, the sea ice gets thicker and spreads further each winter, but this hasn’t happened for the past few years.
Last month, the ice cap had shrunk to its smallest size since scientists began keeping records of it 38 years ago. The weather in the Arctic has been unusually warm this winter. Some days, temperatures have been 20 degrees Celsius higher than is normal for this time of year. This month, the temperature was above 0°C at least one day.
