Extreme weather has significant impacts on human society as well as natural ecosystems. For example, a global insurer Munich Re estimates that natural disasters cause more than $90 billion global direct losses in 2015.
Extreme weather is real and will disrupt our planet for thousands of years..
In May 2019, the levels of the greenhouse gas reached 415 parts per million (ppm), as measured by the National Oceanic and Atmospheric Administration (NOAA) at its Mauna Loa Observatory in Hawaii. During the ice ages, carbon dioxide levels in the atmosphere were around 200 ppm. And during the interglacial periods — the planet is currently in an interglacial period — levels were around 280 ppm, according to NASA. Humans are burning fossil fuels, causing the release of carbon dioxide and other greenhouse gases. And as a result, every year, the Earth sees about 3 ppm more carbon dioxide in the air. It reached 419 ppm this year (2021).
Thw Arctic Circle is already recording 118 F degrees on rhe ground. Air temperature is.86F. That's an anomalously high temperature for the Arctic Circle — and one that could exacerbate the region's melting permafrost, which is the only thing preventing ancient caches of greenhouse gases from reentering Earth's atmosphere.

The hot solstice temperatures are just the beginning. Precisely one year ago, on June 20, 2020, the same region of Siberia recorded the first 100 F (38 C) day above the Arctic Circle — the hottest temperature ever recorded there. The sweltering day in Siberia fits into a larger climate change trend. For years, average temperatures in the Arctic have been rising at a far faster rate than anywhere else on Earth, largely due to melting sea ice.
