The Met Office’s recently published report on the State of the UK Climate 2020 indicates that climate change continues to have a material impact across the UK.

The country’s climate has continued to warm, with 2020 the first year to feature temperature, rain and sunshine rankings all in the top 10.

The NFU climate change team has pulled out some headline figures from the report, given the importance to British farming of understanding changing weather patterns.
