Evolution of the ozone layer: on the right track but slowly

Measurements of Antarctica until mid-September reveal the ozone shortage in Antarctica at this time. Data appears to follow the same line as last year, i.e. they are neither very good nor very malos.La the main difference in recent years is
that the ozone shortage is occurring more and more later. Although scarcity usually begins to occur in the first half of August, last year and this year the start of the lack of ozono.El most critical period has been delayed to the second half of September and early October, although data relevant to human health
are not expected. It can be said that the shortage of ozone is maintained and that the long-term trend can be positive. In any event, the final data will be provided in the second half of October.

Zertan da ozono zuloa aurten?
Azken urteotan legez, ozono mailaren eboluzioaren inguruko datuak ematera gatozkizue oraingo honetan ere. Ozono mailaren beherakada poloetan antzeman zuten orain 25 urte, Hego Poloan batez ere. Baina beherakada ez da urte osoan gertatzen, hemisferio horretako negutik udaberrira... [+]
