Climate Shift Index

The Climate Shift Index was mentioned by ITV Anglia presenter Chris Page in his forecast last night.

It is produced by Climate Central who perform a similar role to Carbon Brief in providing reports in the arena of Climate Change.

This work is significant as the Trump administration is deleting and stopping access to research and reports on Climate Change in the USA. This will not stop it happening by the way... it will just make it harder to prepare, and make the impacts even worse... and not just in the US.

Check out the Global Map showing how much the climate has shifted.

The Climate Shift Index (CSI) is a system that quantifies the influence of climate change on local daily temperatures around the world.

The Climate Shift Index ranges from -5 to +5. Positive levels indicate temperatures that are becoming more likely due to climate change (negative scores indicate conditions that are becoming less likely).

A CSI of level 5 means that a temperature is occurring at least 5 times more frequently when compared to a world without human-caused carbon pollution. This temperature would be very difficult to encounter in a world without climate change – not necessarily impossible, just highly unlikely.

Here's how to interpret the scale from 1-5 and in the negative too.


And here is the interpretation guide for specific numbers. 
Zoom in to your local area to see what the likely impact of climate change is on the weather in your area as the summer goes on....
