NASA updates ‘climate spiral’ with September temperature

NASA has updated its so-called “climate spiral”, which shows monthly changes in the planet’s temperature from 1880 to today, visible with colored lines around three circles, indicating plus or minus 1 degree Celsius using the first year of research as the base indicator. (1880).

The vortex now includes the last month of September, the hottest month on record. We can see, in the chart, increasingly stronger colors in recent decades. In September 2023, it will be possible to see how the circular line moves away from the 0°C mark.

According to the g1,The visualization depends on the index GIS Surface Temperature Analysis (GISTEMP v4), which collects global surface temperature data. Check out the spiral below (for a better view, expand the video):

• The spiral is a way to show the monthly change in Earth’s temperature relative to the average before the Industrial Revolution.
• The new version was designed by Mark Subbarao, leader of NASA’s Scientific Visualization Studio;
• It highlights the last months of this year, especially September.
• July and August were also very hot months, which could make 2023 the hottest year on record.

[Setembro] It was the month with the largest temperature anomalies on record since we made measurements. So, according to NASA, it recorded an additional 1.47 degrees Celsius compared to the reference period from 1951 to 1980. That’s why it appears on the graph outside that circle of one degree of anomaly, almost to one degree and the temperature anomaly means

Regarding the rise in temperatures since the last century, Gavin Schmidt, director of the Goddard Institute for Space Studies (GISS), the NASA laboratory responsible for the project, said, “What is striking is that these record values ​​​​occur before the peak of the current El Niño phenomenon in 2016.” [o ano mais quente até então] “The previous record values ​​were in the spring, after the peak.”

Chart sources

The graph was originally designed by climate scientist Ed Hawkins, of the National Center for Atmospheric Science at the University of Reading (UK). A spiral-shaped version was released at the opening ceremony of the 2016 Olympic Games, in Rio de Janeiro (RJ).

Bar chart

Hawkins even translated climate escalation into a series of lines. The pattern gained so much popularity that it was printed on pants, sandals and even cars. look:

Explanation of the chart

• In the visualization, we see three blue lines representing cold years, while red lines indicate warmer years;
• Each bar indicates the average temperature for a given area in a given year;
• Hawkins interviewed g1 In 2019, he stated that the model’s simplicity is very useful, as it is “a good way to start a conversation” about climate change that ends up being “hidden” and lost in the more complex tables and graphs used by meteorologists.

Scientists often talk using complex diagrams. This is the way I found to be able to communicate with more people: We use colors to represent changes, blue for cold years and red for warmer years, so there is no difficulty in understanding.
