In the UK it feels like winters are getting warmer but the entire year is usually rainy. We remember things being a bit different when we were younger. Laura, Antonia and Ellie discuss evidence for changing of the seasons and look at the effect this has globally on extreme events such as wildfires, animal migration and plant growth. They also look at some research that identified new seasons and suggests humans should change their relationship with them.

Fact check:

• Seasons on a social level
• Summers getting hotter in the northern hemisphere
• Wildfire season in California is almost all year round
• New record high temperature in continental Europe
• There is less difference between UK summers and winters now compared to the 1700s
• Mouse-ear cress could be better adapted to warmer winters than we thought
• Some crops need a cold spell
• Some species of wales are altering their migration patterns
• Trees lose their leaves because falling temperatures halt chlorophyll production
