The carbon dioxide emissions from wildfires in the northern hemisphere in 2022 already exceed the emissions of the whole European Union.

The highest temperature measured (“in shade”) in 2022 is 63 degrees Celsius.

The carbon dioxide emissions per person are highest in oil-producing small Arab countries, tightly followed by Luxembourg, Canada, Australia, Estonia and USA. The emissions by an average American are approximately double of that of and average Chinese. An average European’s emissions are currently slightly above an average Chinese, but whereas the emissions by Europeans are decreasing, those of Chinese are increasing. An average Russian emits much more carbon dioxide than Europeans, being in the middle between Chinese and Americans. Within Europe, an average Finn emits twice the amount of carbon dioxide as an average Swede. Currently, an Indian emits about 15 % of the emissions of an American, and an African only 5 %.

Humans are using more than half of all habitable land to either agriculture, roads or habitation. Forests make up ca. 35 % of habitable land, and a large part is subject to human activities, so one can estimate that currently less than 20 % of all habitable land is free from human use. Out of the agricultural land use, 75-80 % is used for livestock (either directly or to produce fodder).

Virtually all seas are overfished. The present aquacultural practices do not decrease overfishing, as most of the feed for the cultivated preferred species is obtained by catching and processing less valuable species.

The sea ice extent in Antarctica has been the lowest ever throughout 2022 and also in Arctic much less than the long-time average. While the Arctic temperatures in 2022 are generally much higher than the long-time average, the area between Alaska and Eastern Siberia makes a notable exception as it has been very cold there.

The world’s glaciers have lost more than 25 meters of ice by 2022 relative to the situation in 1970. Since the water from glaciers is the primary water source in many areas, and glaciers have melted, the water availability decreases.

In England, July was driest after 1935. Lake Mead (the most important reservoir in Colorado river) is drying up. In other places deadly floods occur (Kentucky, South Korea)
