The header image on my homepage comes from showyourstripes.info and represents the annual average temperatures for Canada from 1901-2018 using data from Berkeley Earth. Similar images can be generated for other regions or the whole planet. From their FAQ page:

“These ‘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 2018. For the UK, USA, Switzerland & Germany, the data starts in the late 19th century.“

The one for the entire globe using data from 1850-2018 is even more striking. Will I be around long enough to see the cooler shades return?
