CLIMATE ANALYTICS: Paris Agreement 1.5 °C Temperature Limit

"Since 2009, more than a hundred Small Island Developing States, Least Developed Countries and many others have been calling for limiting global temperature rise to 1.5°C above pre-industrial levels to prevent the worst of climate change impacts. The inclusion of a 1.5°C temperature limit in the 2015 Paris Agreement was a major victory for vulnerable countries."

CARIBBEAN NATURAL RESOURCES INSTITUTE: Communicating climate change: A toolbox for local organisations in the Caribbean

This toolbox has been developed to help local (non-governmental, community-based, and grassroots) organisations become more effective in telling their climatechange stories and making their voices heard in lobbying and advocating for thepolicies, laws and other actions necessary to mitigate and adapt to climate change atthe international, regional, national and local levels.


‘warming stripe’ graphics are visual representations of the change in temperature as measured in each country over the past 100+ years. Each stripe represents the temperature in that country averaged over a year. For most countries, the stripes start in the year 1901 and finish in 2020.

The stripes turn from mainly blue to mainly red in more recent years, illustrating the rise in average temperatures in that country.

You can generate warming stripes for most countries and for some cities around the world using this brilliant generator. The graphics have a  CC-BY 4.0 license, so can be used for any purpose as long as credit is given to Professor Ed Hawkins (University of Reading) and a link is provided to the #ShowYourStripes website.
