No doubt: the earth is warming

From the end of XIXe Century, the average temperature of the Earth has increased by 1.2 C. Questionable, human activities. NASA researchers are now offering us another way to visualize this temperature evolution.

The Anthropological Global Warming Not necessarily felt on a daily basis. So, to help us understand the urgency of action, researchers are constantly releasing new images. So popular now Warming Lines, Imagined “warming lines” a Climate Analyst Ed Hawkins, from the University of Reading (UK).

Today, researchers NASA Give us a chance to visualize the evolution of the situation in a different way. Through a bell-shaped map showing the distribution Temperature anomalies On the ground, each year, between 1951 and 2020 – on an average, the average for the period 1951-1980. Shifting the map to the right shows a significant increase in frequency over time Contradictions Hot.

All numbers are in red

The researchers note that the curve is flat when it is thick on the red side. The questionable, extreme heat wave will be more and more wide. As a result, the result of different regional warming rather than an increase in temperature variation at a given location.

These curves are built from more than 26,000 data Weather stations Above the ground. Data analyzed using a method that takes into account the different spacing between these stations and the effects of urban warming. Bind to 2020 – 2016 – Note that NASA recorded an average of 1.02 C warmer than average between 1951 and 1980. In more detail, now the last seven years … Seven warmest years on record.
