Timelines for record temperatures

Speaking of the heat wave in Europe, Pierre Breteau for Le Monde charted record high temperatures using a step chart for each weather station in France: These graphs represent, for a part of the 146 stations for which Météo-France provided us with the data, the level of the most extreme temperatures ever recorded and their date. The data are fragmentary because it is difficult to go back beyond the 1990’s,...

Climate spiral to show temperature change

Say what you will about circular visualization, but the spiral plays. This one from NASA shows global temperature change over time: The visualization presents monthly global temperature anomalies between the years 1880-2021. These temperatures are based on the GISS Surface Temperature Analysis (GISTEMP v4), an estimate of global surface temperature change. Anomalies are defined relative to a base period of 1951-1980. The data file used to create this visualization can...

Days since record-high temperatures

Here’s a fun/alarming weather map from The Pudding. Using data from the Applied Climate Information System, they show the number of days since a record-high temperature in hundreds of U.S. cities. The counters are in the style of those signs in factories that show days since the last injury. Tags: climate, Pudding, temperature

All-time temperature records broken in 2021

Using data from NOAA, Krishna Karra and Tim Wallace for The New York Times mapped all-time temperature records set in 2021. Red indicates an all-time high, and blue indicates an all-time low. Circle size represents the degree difference from the previous record. Tags: climate change, New York Times, temperature

Mapping the probable heat around the world

Earth is getting warmer, and the previously abstract concept seems to grow more concrete every day. Probable Futures mapped increasing heat, decreasing cold, and shifting humidity under different warming scenarios. You have the global view shown above, and then when you zoom in enough, you can click on grid cells for the model estimates. Dots on the map point to a handful of short stories on how warming has changed...

Historical context for the heat in the Pacific Northwest

It’s been hot in the Pacific Northwest the past few days. NYT’s The Upshot plotted the temperatures against previous max temperatures since 1979. Hot. Tags: climate change, temperature, Upshot

Low temperatures map of the United States

Based on data from the Global Forecast System, The New York Times mapped the lowest temperatures across the country between February 14 and 16. The blue-orange color scale diverges at freezing, which creates a striking image of a very cold country. The dotted lines and temperature labels make the patterns especially obvious. As someone who lives in an orange area, I was shocked by all of the blue. Stay safe....

Quilt that shows daily high and low temperatures

Reddit user quantum-kate used daily high and low temperatures in Denver in 1992 as the basis of this quilt. I feel like I should learn to knit. Tags: quilt, temperature

Increasing ocean temperatures, decreasing ice

For National Geographic, Kennedy Elliot made a series of heatmaps that show the relative shifts in the ocean: The oceans don’t just soak up excess heat from the atmosphere; they also absorb excess carbon dioxide, which is changing the chemistry of seawater, making it more acidic. “Ocean acidification is one simple and inescapable consequence of rising atmospheric CO2 that is both predictable and impossible to attribute to any other cause,”...

A long distance relationship between a temperature difference

Everyone’s story is a little different. Alyssa Fowers tracked her long-distance relationship in the context of the temperature between two locations and the travel to and from. Tags: relationships, temperature
