How do the warming stripes start conversations about climate change? #ShowYourStripes
They are stark visuals which, with a single glance, instantly communicate the simple message that the climate is heating up.
Their strength is the innovative ways that people have adapted them.
At London Fashion Week, @HouseOfTammam put on a catwalk show with dresses, accessories and a cape with the stripes as a theme, reaching a new audience and winning awards for sustainability engagement.
The rock band @ENTERSHIKARI used the warming stripes to start climate conversations with music fans during a sell-out festival tour.
Another audience was reached by @NetZeroMN who wrapped his @Tesla in Warming Stripes. This design started more climate conversations in a few days than the rest of his life put together!
Importantly, the graphic causes people to ask questions: 'what have you done to your car?'.
Reaching broad audiences through newspapers, magazines and other media #ShowYourStripes
And, innovative light shows communicating to yet another type of audience and starting more conversations. #ShowYourStripes
At the centre of the groups using the Warming Stripes has always been the TV weather forecaster community, led by @WeatherProf. These trusted voices are an important way that millions of people hear information about how our climate is changing.
The warming stripes have also been used prominently by those campaigning for more rapid action, consistent with the Paris Agreement to limit global temperature rise. #ShowYourStripes
And, today, cyclists from @ClimateClassic are cycling along the 1m elevation line in the Netherlands to highlight the risks from sea level rise.
Buildings and walls have been painted from Spain to Scotland to Jersey to Puerto Rico, amongst many others. #ShowYourStripes
In Leipzig, a crowd funded effort to paint the Sachsen Bridge has created a version of the Warming Stripes that is visible from space! #ShowYourStripes
When it is published in October this year, @GretaThunberg's new book on the climate & ecological crises will have the Warming Stripes on the cover, bringing the #ShowYourStripes graphics to a new audience.
And this use of the graphics as a book cover has a nice link back to the first time I talked about the Warming Stripes at @hayfestival in 2018 at an event with the author @nicolakidsbooks about communicating climate change.
The stripes on the screen are for the town of Hay.
So many other novel & creative ways that people have adapted the warming stripes concept. Wrapping street posts, blowing beautiful glass vases (@CathrynShilling), decorating a shower cubicle and even a snowboard! #ShowYourStripes

Whenever climate change & UK heatwaves are discussed someone will always say: 'but what about 1976?', as if this was evidence that the climate has not changed.
And, yes, summer 1976 was hot in the UK. It may not be obvious which map is 1976 when comparing with the last 8 summers.
But, taking a global view is important. Variations in the weather mean that locally some years are hotter & some cooler.
1976 clearly stands out as unusual. It was far cooler virtually everywhere when compared to the last 8 summers.
The UK happened to be an exception that year.
Local experiences of weather events are important - people are realising that we are living through more frequent & more intense heatwaves overall.
But relying on feelings about events from nearly 50 years ago is not a reliable way to understand the changes that are happening.
Delighted that the Warming Stripes were chosen for the cover of @GretaThunberg's new book.
These 172 coloured stripes represent how global average temperatures have increased from 1850 to 2021. Billions of observations taken by many thousands of observers in one simple graphic.
The graphic used for this book continues the stripes backwards in time on the spine & back cover. For the period before 1850, information from 'paleo' sources are used, i.e. data from tree rings, corals etc. Because of the dimensions of the book the back cover goes back to 1630s.
The paleo-data is actually available for the last 2000 years, and highlights the unprecedented nature of the recent warming. The rapid change is mainly caused by our burning of fossil fuels to generate energy, starting with the invention of the steam engine.
When making policy decisions with uncertain information, the most likely outcome is usually not the most relevant.
This is because unlikely events do happen. And these unlikely events can have severe consequences.
Policy-makers need to avoid severe consequences occurring.
With covid, the potential severe consequences are that health services are overrun with patients, causing cascading effects with staff off sick, cancelled appointments, deaths, more long-covid and knock-on effects throughout society.
Some figures from Chapter 1 of the new IPCC AR6 physical climate science report: ipcc.ch/report/ar6/wg1…
1/ Baselines and reference periods. Ever been confused about different climate baselines? Figures 1.11 and 1.12 may help, along with the discussion in Section 1.4.1.
2/ Climate variability. Short term fluctuations in the climate can temporarily obscure or enhance longer term trends. The size of the fluctuations depends on the variable of interest and spatial scale.
Figure 1.13 and Section 1.4.2 may help explain this.
3/ Emergence. Both the rate of change & the size of climate fluctuations matter for how climate change is experienced. The tropics tends to warm less but has smaller variations so has a larger 'signal-to-noise' ratio; the change is more apparent.
See Figure 1.14 & Section 1.4.2.
Dear @BBCNews: this phrase, used in several recent articles, is not a fair representation of the science on extremes.
”Experts say that climate change is expected to increase the frequency of extreme weather events, but linking any single event to global warming is complicated.”
How about “Experts say that climate change is already increasing the frequency of extreme weather events, and many single events have been shown to have been made worse by global warming.” instead?
Perhaps @BBCAmos, @MattMcGrathBBC, @RHarrabin or @davidshukmanbbc could chat (again?) with the news team? The science has moved on and it would be great to see that reflected in the news coverage of extreme weather events, rather than the current inaccurate stock phrase.
