"Absolutely all global environmental characteristics are deteriorating, except for those, this is the only exception that characterizes the state of the ozone layer," RIA Novosti quoted Danilov-Danilyan as saying at the Altai Economic Forum "Thread of Nature".

He noted that the situation with the ozone layer was improving after the adoption of the Montreal Protocol and the implementation of its obligations.

The scientist added that the concentration of greenhouse gases in the atmosphere is growing in the world, the area of forests is decreasing, and chemical poisoning of soils continues.

Earlier, US President Joe Biden said that global warming remains the only real threat to humanity.
