After the first bang of the @IPCC_CH AR6 report, it's time to look at my favorite part of the report:
visuals in the SPM.
It was a privilege to work with a team of #dataviz and information design experts @angelamorelli @tomhal99 @jordanharold on these visuals

The first visual shows us that human influence has warmed the climate at a rate unprecedented in at least 2000 years.
I really like how it contrasts the climate our societies were used to during their development with the evidence that we are responsible.

The second visual shows how observed warming is driven by emissions from human activities.
It shows that greenhouse gases alone would already have warmed the planet by 1.5°C, but air pollution is currently cooling it. Both need to be tackled.

Climate change is already affecting us our activities contribute to many observed changes in weather and climate extremes.
Each red hexagon represents a world region in which observed hot extremes have increased, with the number of dots representing our confidence.

This visual was actually too large to fully fit in a single tweet. Here is the same visual for heavy precipitation and droughts.
We see it's happening and we know it's us.

The fourth visual shows scenarios that help @IPCC_CH describe the implications of our emission reduction choices.
They cover a full range from very high emissions that require a roll-back of climate policies to very low emissions that require deep cuts in the next decade. (9/n)

The final visual for today shows that every increment of warming matters for climate impacts.
That is true for temperatures. (10/n)

As well as for precipitation and soil moisture - important for the impact heatwaves have on society and crops.

Enough for today. Stay tuned for the second part of visual over the next days. (end)
