An article from An tEolaí, "The Latest News about the Ozone Layer."
Mar is eol do léitheorí an tEolaí, tá an ciseal frith- ultraivialait ózóin thuas san atmaisféar á laghdú (1) le deich mbliana nó mar sin ag ionsaí ceimiceán truaillithe ar leith. Is iad na clórafluaireacarbóin (CFC) is measa i laghdú an ózóin. (2) Anois tá eolaithe i Meiriceá tar éis a fháil amach (3) go bhfuil an méadú de na ceimiceáin seo san atmaisféar ag laghdú (4) ionas go measann siad nach (5) mbeidh siad ag méadú a thuilleadh faoi dheireadh an chéid. (6) Measann siad freisin go mbeidh an ciseal óozóin in ann (7) teacht ar ais ina dhiaidh sin bíodh is go leanfaidh an teacht ar ais ar feadh suas le céad bliain. (8)
Ní hionann seo agus sábháil iomlán an chisil ózóin in aon chor ach ciallaíonn sé go bhfuil na bearta atá i réim ag rialtais agus tionscail ag dul i bhfeidhm ar an bhfadhb. (9) Ciallaíonn sé freisin gur gá na bearta céanna a leanúint agus a leathnú chun (10) an ciseal ózóin a thabhairt ar ais go críochnaithe. (11)

(1) literally "at its reducing" i.e. "is being decreased." This is one way of rendering a passive in Irish. The instrument or agent is marked by "ag." The ozone layer is thus being decreased "ag ionsaí ceimiceán truaillithe ar leith," - "by the attack of special chemicals of pollution." Note that ceimiceán is here in the genitive plural, a form which looks like the common singular.
(2) "It is clorofluorocarbons which are the worst in reducing the ozone." "Is measa" is the superlative of "olc" - bad. Note that "ózóin" is genitive following the verbal noun "laghdú."
(3) "scientists . . . have found out." (literally "scientists . . . are after finding out."). tá + tar éis + a + verbal noun is one way of forming the perfect tense in Irish.
(4) "that the increase of these chemicals in the atmosphere is decreasing"
(5) Nach (eclipsing) is the negative form of "go" - "that"
(6) This rather long sentence is made more difficult because there are several levels of subordination. Take it a phrase at a time and it will be easier. The entire sentence can be translated: "Now scientists in America have found out that the increase of these chemicals in the atmosphere is decreasing, so that they think that they (the chemicals) will not increase any more by the end of the century."
(7) "beidh . . . in ann . . ." - "will be able to . . ."
(8) "even though the return (of the ozone) will continue in duration up to a hundred years." i.e. the return of the ozone layer to its former condition will take about a century.
(9) Another tricky sentence: " This is not at all ("in aon chor") the same as the total preservation of the ozone layer, but they it does mean that the plans which are in effect in government and industry are going into operation on the difficult problem."
(10) "chun" + object + "a" + verbal noun - "in order to" do something.
(11) It also means that it is necessary to continue and broaden the same plans in order to finally bring back the ozone layer."
