February record heat in the USA: It's already 30 degrees Celsius in Saint Louis. By Wednesday morning, temperatures will even drop below freezing point.

Experts attribute the violent temperature fluctuations to climate change and the El Niño weather phenomenon. Last month was the warmest January ever recorded worldwide. In the US state of Texas, unusually high temperatures and strong winds are encouraging the rapid spread of bush fires. Governor Greg Abbott declared a disaster for 60 communities on Tuesday so that aid can be better coordinated centrally. By Tuesday, the fire had nearly doubled in size.
