Europe is very cold now. This is not normal. Heavy snow is falling. The temperature is very low. This makes travel hard. Many planes are not flying. Roads are also difficult. Many people are stuck.
Schiphol Airport in Amsterdam has many flight problems. More than 700 flights stopped there. KLM is a Dutch airline. They say this is a big problem. KLM needs special liquid. This liquid helps planes fly in ice. They worry they will not have enough. More flights may stop.
Other airports in Europe have problems too. In France, about 100 flights stopped. This was at Charles de Gaulle Airport. Orly Airport stopped 40 flights. French helpers asked airlines to fly less. This helps with the problems. London and Brussels airports also have delays.
The cold weather is bad for driving. In France, five people died in car crashes. The roads have much ice. Bosnia also has bad roads. Trucks and trains are also late. Travel is very slow.
Many people sleep at airports. More than 1000 people slept at Schiphol. Tents were made for them. They got food and drinks. They also got beds. We do not know when the cold will stop. Europe is trying to manage this cold.
