  into an extratropical system as it approached the UK. While not expected to bring hazardous weather, Dexter has played a role in shaping our current conditions. Initially forecast to pass northwest of the UK, Dexter’s influence was expected to be limited to a spell of wet weather. However, by midweek, the story

• How weather and climate change are shaping global food security

  insecurity There are a number of factors that could impact food security. These include:  Rising temperatures Average global temperatures are projected to rise in the coming decades. While this may extend growing seasons in some mid- to high-latitude regions, it is likely to reduce crop yields

• Understanding long-range forecasts: Science, skill, and application

  to predict the exact weather on a particular day months ahead, forecasters can estimate the probability of certain conditions, such as a wetter-than-average season or an increased risk of heatwaves.
