Frost Days

I drew up the following chart using data from the Met Office National Climate Information Centre HadUK-Grid climate data.

graph of frost days

We have seen long-term average temperatures increase, in England since the 1960s, with the 30 year average increasing by 0.5 degrees Celsius (see Central England Temperature with Climate Change Projections).

In this graph you can see how the lower extremes have changed. The number of days with an the air temperature below freezing point (an ‘Air Frost’) have decreased from a 30 year average of 53 days per year, down to 43 days per year. This trend is set to continue. And it does affect what plants – as well as pests and diseases – are able to survive our winters.

16 October 2018

Prompted by calls from the Paris climate summit, the IPCC commissioned this report to look at the challenge of limiting climate change to 1.5 degC compared with 2 degC. The consequences for the world of just that half-a-degree difference are stark. And it is a real call to arms for the global race to zero carbon emissions.

The aim of the presentation is to help explain the link between Extreme Events, which can dramatically affect our lives, and Climate Change, which may seem less urgent and is often talked about as rather abstract changes in global average temperatures.

Special Report on Emission Scenarios (SRES)
1 January 2014

The greatest source of uncertainty for anyone trying to predict how the climate will change is us. How will we behave in the future? Will we take the issue seriously and rapidly cut our emissions of greenhouse gases? Or will it be business as usual? There are a number of Emission Scenarios, which have been modelled to try and understand this. This section has been updated to include the new AR5 scenarios.
