This visualisation is misleading because the visual area covered increases quadratically as the radius increases, and (less misleading) the velocity of the 'pen' increases linearly too. But it's measuring a difference (not an absolute quantity): so velocity and (especially) area are arbitrary. I could take the same graph and apply it to the period between 1890 and 1945 and it would seem just as concerning, with a dif…

A significant part of the debate is simply scientists going, "please, for the love of god, look at the data."

>A significant part of the debate is simply scientists going, "please, for the love of god, look at the data." Nobody! wants to look at the data. Climate change isn't about science or data anymore. It's about politics. The first group of climate change I find are the doomers. They got bored with Mayan calendars and Y2k dates. They jumped into climate change and we are literally on the verge of extinction always. When…

So, the question moves to: "How to rescue the debate from the politics?"

These visualizations are so simple to understand and shocking to the core. We need more examples like this in mainstream media.

Do you think if people saw more of these in mainstream media there would be more action demanded by them from their governments/policy makers?

Very cool visualization! What are the causes of the rapid acceleration starting in the 80s, I assume globalization had something to do with it?

The reason for the acceleration is because most of the greeh house gas emissions (CO2, CH4 etc) once emitted will stay in the atmosphere for a very long time (100s of years, they accumulate). PLus we are emitting these at a much faster pace than they can be removed from the atmosphere by natural processes (we rely on nature because currently, we do not have technologies to remove GHGs from the atmosphere at scale economically). So it has a compounding effect in terms of temperature response over time...

Have tried to share some thoughts on this here, have a look if you like

I'm not familiar with any issue that was rescued from politics. I very much doubt this is possible in any reasonable scenario when excluding violence.

What I was illustrating is that none of the groups in climate change care at all about climate change. If you extricate this issue from politics, it just goes away.

The change of color also and the fact that it’s temperature anomalies, not average temperature. I wonder what is actually behind ’temperature anomalies’, what does it mean, how is it calculated?

https://en.wikipedia.org/wiki/Temperature_anomaly As I understand it, this is a more useful number when trying to measure changes of average temperature over time.

Ok, I found the answer: it’s supposed to be the average of the difference of temperature over close to a million of region on the earth.

Yes I can see them reaching a wider audience and having more impact
