Global warming in recent decades, however, has been caused to a considerable extent by man. Normally, a global temperature rise of 2 degrees lasts several thousand years. For such an increase man did not even need a whole century. In the last two decades alone, more drastic warming has become apparent.

These, however, provide informative data from large parts of the world and show a general increase in air temperatures. Especially in the last 10 to 20 years, the temperature rose more strongly than in the previous decades. All 185 measuring stations provided continuous data during the entire observation period. Changes in these average values are therefore not due to the fact that individual stations failed for a longer period of time or new ones were added in particularly warm or cold regions. The 10-year average is given in each case.

In the continents of Central and South America, which are not shown here, there were no weather stations for the period under review which continuously provided corresponding values.

The graphs show the average daily temperatures. It can already be seen quite clearly that there has been a high rise in temperatures worldwide since the 1980s. Especially noticeable are the developments in Europe, North America and Asia, where there are partly considerable temperature increases. In the countries of Oceania, on the other hand, the development has even been declining for some years. Antarctica is not listed here due to a lack of consistent data series. However, stagnation of the temperature rise can (with restrictions) also be observed there.

Since this value is not a 10-year average, but the warmest month within 10 years, global warming does not seem to have too dramatic an effect, at least on temperature extremes.
