Idatha ye-New Actuaries Climate Index ebikwe namuhla yizinhlangano ezimele umsebenzi we-actuary e-Canada nase-United States ikhombisa ukuthi isilinganiso seminyaka emihlanu sokuguquguquka kwesimo sezulu esibi kakhulu emazweni womabili siseseqophelweni eliphezulu ebusika buka-2016-17 kanye nentwasahlobo ka-2017.

"Amazinga olwandle, amazinga okushisa aphezulu, kanye nemvula enamandla kuyaqhubeka kubizwa ngokuhambisana nezinkambiso zabo zomlando, okugcina inkambiso yesikhathi eside yamanani aphezulu e-ACI," kusho uDoug Collins, usihlalo weClimate Index Working Group.

Uma kulinganiswa nedatha entsha yasehlobo lika-2017 efakiwe, isilinganiso seminyaka emihlanu esinyakazayo se-Actuaries Climate Index sihlala siku-1.14, inani eliphakeme elirekhodiwe elatholwa okokuqala, futhi laqhubeka kusukela, ebusika 2016-17. Inani lenkomba eliphakeme libonisa ukuchezuka okuqhubekayo kwesimo sezulu nezinga lolwandle ngokwedlulele kusukela kumaphethini omlando alindelwe kulawa mazwe amabili.

Ukwehla kwevelu ye-ACI yesizini akuzange kuthinte isilinganiso esinyakazayo seminyaka emihlanu. Inani lesizini le-ACI lehlobo lika-2017 lalingu-1.45, uma liqhathaniswa no-1.66 entwasahlobo ka-2017, okwenza ihlobo lango-2017 libe inani lokuqala lesizini le-ACI kumasizini ayisishiyagalombili ngaphansi kuka-1.5. “Nakuba inani lesizini lingameleli ukweqisa okubonwe eminyakeni emibili edlule, inani belisaphezulu kakhulu ngokomlando,” kusho uCollins.

I-Actuaries Climate Index isekelwe ekuhlaziyweni kwedatha yesizini evela emithonjeni engathathi hlangothi, yesayensi yezingxenye eziyisithupha ezihlukene zenkomba eziqoqwe kusukela ngo-1961. Izilinganiso zenkomba ziyashintsha emazingeni okushisa aphakeme naphansi, umoya onamandla, imvula enamandla, nesomiso, kanye izinguquko ezingeni lolwandle, ezivezwe ngamayunithi okuchezuka okujwayelekile ukusuka kuncazelo yenkathi yereferensi yeminyaka engama-30 ka-1961 kuya ku-1990 e-United States naseCanada kuhlangene.

Inkomba, exhaswe yi-American Academy of Actuaries, Canadian Institute of Actuaries, Casualty Actuarial Society, kanye ne-Society of Actuaries, yakhelwe ukuhlinzeka izazi zezibalo, abenzi bezinqubomgomo zomphakathi, kanye nomphakathi jikelele ngedatha eyinhloso mayelana nezinguquko zemvamisa yezibalo. izehlakalo zesimo sezulu esibi kakhulu emashumini eminyaka amuva nje.
Amanani abuyekeziwe athunyelwa njalo ngekota ku-ActuariesClimateIndex.org njengoba idatha yesizini ngayinye yesimo sezulu itholakala. Izinhlangano futhi zenza inkomba yesibili, i-Actuaries Climate Risk Index, ukukala ukuhlobana phakathi kwezinguquko zemvamisa yezenzakalo ezimbi kakhulu njengoba kulinganiswa inkomba nokulahlekelwa kwezomnotho, ukufa, nokulimala.

LOKHO ONGAKUTHATHE KULESI SIHLOKO:

The index measures changes in extremes of high and low temperatures, high winds, heavy precipitation, and drought, as well as changes in sea level, expressed in units of standard deviations from the mean for the 30-year reference period of 1961 to 1990 for the United States and Canada combined.
