Cherry trees bloom first in Japan due to climate crisis

In Japan the date of maximum flowering this spring season was March 26th, surpassing the previous record holder in 1409 of March 27th. This marked the ninth consecutive flowering earlier than normal. In Kyoto it is the last early bloom over the past 100-150 years.

According to the Japanese Meteorological Agency, during this period, the average temperature in Kyoto increased by about 6 degrees in the last seasons. And this is due to the global warming. Trees have bloomed earlier in several cities in USA, even early respect their season.

According a study of Osaka University, flowering had never occurred so early since the year 812. The previous record dates back to the spring of 1409, when the peak of flowering took place on 27 March. Sakura cherry trees originate from Japan, but were introduced to the United States in the early 1900s.

Since the beginning of the 19th century, the date of full cherry blossom in Kyoto has fallen earlier and earlier than the historical average, gradually moving from mid-April to the beginning of the month.

European Alps: flora and fauna are in danger of disappearing by 2100

According to recent estimates, in fact, about 45 percent of European Alps flora would be at risk of extinction by 2100, due to the climate crisis and the rise in the earth's temperature.

Alps have 13 thousand plant species, of which about 8 percent are endemic, but threatened by climate change. Glacier buttercup or the alpine androsace are also at risk, as they are gradually migrating to ever higher altitudes, competing with the rarer species that live at lower temperatures, at the top of the mountains.

And with flora, fauna also moves, in a vicious circle also confirmed by a study entitled The consequences of glacier retreat are uneven between plant species. The distance from the main anthropic activities is no longer enough: the effects of climate change are felt even at high altitudes, modifying microclimates that have remained unchanged for centuries.

If in the next 100 years the global average temperature increases by 3 degrees centigrade, in the northern hemisphere the vegetation areas will move about 600 kilometers from south to north and 600 meters upwards. Climate change is not only a danger to plants but also to animals.

This is the case of the ibex, devoid of sweat glands and which must therefore move to where it is colder. But also the white hare, the ptarmigan, the stoat and some species of butterflies are at risk.
