BotCopernicus - Minimum and maximum temperature

Climat change and global warming

Climate change has many facets, and one of the most evident is the steady rise in global temperatures.

The first graph shows the absolute global 2-meter air temperature for each month from 1960 to 2025:

• Each line represents a year from 1960 to 2025.
• The red line highlights 2025, showing how it compares to previous years.
• A clear upward trend is visible, especially in the most recent decades, with recent years consistently warmer than the historical average.

The second graph displays the monthly global temperature anomalies — how much each month's average deviated from the 1960–1990 baseline:

• Again, each line shows one year.
• The red line is 2025, which continues the trend of recent years being significantly warmer than the historical norm.

Which day is the hoter and which is the coldest?

I made a quick map showing the typical timing of the hottest and coldest days of the year globally, based on the baseline period 1960–1990.

• The first map shows the day of the year when the maximum daily average 2m air temperature typically occurs.
• The second map shows the day of the year when the minimum daily average 2m air temperature typically occurs.

Color scale represents the day of the year (from 0 to 366), helping to visualize seasonal temperature patterns across different regions of the world.
