Extreme #weather events have become significantly more common in the #Arctic over recent decades, posing a threat to vital polar ecosystems.

Scientists have investigated changes spanning more than seven decades.

They found that in addition to rising average temperatures, Arctic ecosystems are increasingly experiencing a range of extreme weather events, such as prolonged #heat waves, #frost during the growing season, and warm winter spells.

In many areas, some of the examined extreme weather events have only begun to appear in the past 30 years.

One example is rain-on-snow events covering more than 10% of the Arctic land area.

These events can cause #plants to die over large areas and can also cause high mortality in animals, such as reindeer, which can also harm the livelihoods of Arctic people such as reindeer herders.

For people not living in the Arctic, the damage is also important because it can harm the ability of the Arctic to absorb carbon and slow #climate change

World’s vast plant #knowledge not being fully exploited to tackle biodiversity and climate challenges

An international group of researchers says that #biodiversity #conservation and scientific research are not benefiting from the vast knowledge about the world’s #plants held by #botanicGardens, because of fragmented #dataSystems and a lack of standardisation.
