Hi, this is Gregor with a new Weekly Chart about depressing climate change reports.
Two weeks ago, the IPCC published their Sixth Assessment Report on the state of the global climate. And, boy, it’s not looking good. The human influence on the climate is “unequivocal”; the scale of recent changes is unprecedented over many thousands of years; and it’s already causing many heatwaves (record temperatures in Italy and Spain last week), floods (hundreds of people dead or still missing after floods in Germany and Belgium in July), wildfires (Greece and Turkey), droughts, and tropical storms.
And, despite knowing all this, we are still collectively on a fast track toward the climate apocalypse! Global warming will exceed 1.5 and 2 degrees unless “deep reductions” in greenhouse gas emissions occur, and they have to occur fast!
It is hard for many people (myself included) to understand what a global mean temperature increase actually means, so last year I tried explaining the effects of different degrees of warming. For this week’s episode, I thought about another way to make warming degrees a little less abstract and a little more scary.
So, here’s my newest attempt:
Before closing, here are a few charting decisions worth pointing out:
If you're interested in more (depressing) outlooks, I recommend checking out the IPCC Interactive Atlas, which lets you look at various regional datasets and scenarios.
That's it for this week. In case you want to visualize other IPCC datasets in Datawrapper, here's the script I used to load and transform the data. See you next Thursday!
