Slack Randoms: Fixed Gear Skateboard Bikes, Jet Go Karts, Dua Lipa Shoes and More

We use Slack as a workplace communication tool at Pinkbike and we have a #random channel that we use to share an assortment of videos and stories from all corners of the cycling world and beyond… We thought a few moments from the past week were too good not to share with an audience wider, so here are some of the highlights.

The climate spiral
great quotes This visualization shows monthly global temperature anomalies (changes from an average) between the years 1880 and 2021. Whites and blues indicate cooler temperatures, while oranges and reds indicate warmer temperatures. As you can see, global temperatures have warmed primarily due to human activities over time.

These temperatures are based on data from NASA’s Goddard Institute for Space Studies (GISS). Anomalies are defined relative to a base period of 1951 to 1980. The data file used to create this visualization can be accessed here:

The “climate spiral” is a visualization designed by climatologist Ed Hawkins of the National Center for Atmospheric Science, University of Reading:…. Spiral visualizations have been widely disseminated; a version was even part of the opening ceremony of the Rio de Janeiro Olympics.
