The warming that has occurred over the past 160 years has not been the same everywhere. Certain regions, such as the Arctic, have warmed far more than the Southern Ocean for example. How well do our climate models represent these differences? Continue reading Zonal mean temperature change in observations & models

Spiral birthday
Just over a year ago I received an email from a colleague I had never met. Jan Fuglestvedt asked whether I had ever made a spiral version of my global temperature graphics. He ended by suggesting that this was ‘just a (crazy) thought’.
But, it was a Friday afternoon – what else was I going to do? Continue reading Spiral birthday
Choose colour scales carefully
When designing scientific graphics, one key choice is about which colour scale to use (something discussed in several previous posts). The animated graphic below is a simulation of how an image would look to someone who is colour blind (a few percent of men). Continue reading Choose colour scales carefully
Global temperature change as polka-dots
Inspired by National Geographic’s climate change evidence graphics, I made my own global temperature polka-dot visualisations.
In the spirit of experimentation, here are three types, successively getting more complicated. After comments from several people I have made both portrait & landscape versions. I would be interested to know which works best for you. Continue reading Global temperature change as polka-dots
Animating global sea ice changes
Scientists can’t do everything by themselves. We need to engage the millions of citizens who are passionate about knowledge to help solve scientific mysteries and improve our understanding of the world around us.
There are many ways that anyone with a computer can help – volunteer to rescue old weather data or loan your computer’s CPU to simulate the climate, for example.
Those with more technical knowledge might also contribute by communicating climate change in novel ways. Recently, Kevin Pluck (a software engineer) created a global sea ice spiral which gained widespread attention on social media – here he tells Climate Lab Book how he did it.

Climate graphics of 2016
2016 has been quite a year for the climate. Warmest year ever recorded. Record low sea ice extents at both poles. It has also seen many amazing climate visualisations and animations. I have collected some of my favourites on this storify page, including graphics for temperature, sea ice, pressure observations and Hurricane Matthew.
One of the graphics is shown below, mapping temperature changes from 1850-2016, and including the decadal averages of global temperatures. This graphic has been updated from a previous version.
Lancashire temperatures, visualised
This visualisation of temperatures in Lancashire (UK) shows annual mean data from 1754-2015. The long-term warming trend is clear, with variability from year to year, and some temporary cooler periods due to large volcanic eruptions. The average of the 19th century (black line) separates the warm and cold colours.

The visualisation technique of ‘small multiples’ is often used to communicate a simple message. The above example shows maps of temperature change from 1850-2016 – the overall warming trend is obvious even though the details are fuzzy. Continue reading Mapping global temperature change
