Nkhondo Yanyengo: Momwe Kutentha Kwa Dziko Kumakulitsa Mikangano

Vuto la nyengo silikubwera. Ali kale pano. Ngati tipitilira monga kale, kudzakhala kutentha madigiri asanu ndi limodzi padziko lonse lapansi kuposa momwe zinalili asanayambike mafakitale. Cholinga ndikuti achepetse kutentha kwa dziko mpaka madigiri awiri poyerekeza ndi nthawi yomwe ntchito zamakampani zisanachitike, "akutero mgwirizano wamtundu waku Paris. 1,5 madigiri abwinoko. Munali mu 2015. Palibe zambiri zomwe zachitika kuyambira pamenepo. Zomwe zili mu CO2 mumlengalenga zikupitilirabe kukwera komanso kutentha - ngakhale kuli mliri wa corona.

Zosintha zambiri zomwe tikukumana nazo nyengo ndi nyengo zidanenedweratu ndi lipoti la Club of Rome koyambirira kwa ma 70. Mu 1988, asayansi 300 ku Toronto anachenjeza za kuwonjezeka kwa kutentha kwapadziko lonse lapansi mpaka madigiri a 4,5 pofika 2005. Zotsatira zake zinali "zoyipa ngati nkhondo ya zida za nyukiliya". Mu lipoti la nyuzipepala ya New York Times, wolemba waku America a Nathaniel Rich akufotokoza momwe ma Purezidenti a US Reagan ndi Bush, atapanikizika ndi mafakitale amafuta m'ma 80, adalepheretsa chuma cha US kusinthira kugwiritsira ntchito magetsi ochepa komanso kukhazikika. Chakumapeto kwa zaka za m'ma 70, ofufuza a NASA ndi ena anali "atamvetsetsa bwino kuti kuwotcha mafuta kukubweretsa dziko lapansi m'nyengo yatsopano yotentha." Tsopano yayamba.

Oyendetsa mikangano

Mikangano yapadziko lonse ikuwonjezekanso. Anthu ambiri amafuna kukhala ngati ambiri ku Central Europe kapena North America: osachepera galimoto imodzi pakhomo pakhomo, foni yatsopano pakatha zaka ziwiri zilizonse, ndege zotsika mtengo patchuthi ndikugula zinthu zambiri zomwe sitimadziwa dzulo sidzafunika mawa. Omwe akukhala minyumba ku India, Pakistan kapena West Africa amatisamalira: Amapha zinyalala za ogula popanda zovala zoteteza, amadzipweteketsa ndikudziwotcha pochita izi ndi zomwe zatsalira. Timabweretsa zinyalala zapulasitiki, zomwe zimanenedwa kuti zitha kusinthidwa, ku East Asia, komwe zimathera munyanja. Ndipo tikadapita kuti ngati aliyense atachita izi? Osati patali kwambiri. Ngati aliyense akanakhala monga ife, tikadafunikira za maiko anayi. Mukachotsa zakumwa zaku Germany kudziko lapansi, zingakhale zitatu. Nkhondo yolimbana ndi zosowa zochepa idzawonjezeka. 

Malo osungunuka oundana, malo ouma

Madzi oundana a ku Himalaya ndi Andes akasungunuka, gawo limodzi mwa magawo asanu a anthu ku South America ndi ku Southeast Asia pamapeto pake adzapezeka pamtunda. Mitsinje ikuluikulu ku India, South ndi Indochina ikutha madzi. Gawo limodzi mwa magawo atatu a madzi oundana asungunuka kuyambira 1980. Malinga ndi zomwe a Worldwatch adanena, anthu 1,4 biliyoni akukhala kale "m'malo omwe madzi alibe". Mu 2050 adzakhala mabiliyoni asanu. Pafupifupi anthu mamiliyoni 500 amadalira madzi ochokera ku Himalaya okha. Mwachitsanzo, Laos komanso kumwera kwa Vietnam, amakhala kumadzi a Mekong. Popanda madzi kulibe mpunga, kulibe zipatso, kulibe ndiwo zamasamba. 

M'madera ena adziko lapansi, kusintha kwanyengo kumachepetsa zinthu zomwe anthu amafunikira kuti azikhalamo. Pakali pano, 40% yamalo amtunduwu amawerengedwa ngati "malo ouma" ndipo zipululu zikufalikira mopitilira muyeso. Chilala, mikuntho ndi kusefukira kwa madzi zimagunda makamaka iwo omwe ayenera kukhala opanda malo osungira ndi zomwe amalanda panthaka yawo yopanda chonde. Ndi osauka.

Chilala nkhondo yapachiweniweni

Nkhondo yapachiweniweni ku Syria idayambitsidwa ndi nthawi yayitali kwambiri ya chilala chomwe sichinachitikepo. Malinga ndi kafukufuku wofufuza za nyengo yaku America a Colin Kelley, pafupifupi Asuri 2006 miliyoni adasamukira kumizinda pakati pa 2010 ndi 1,5 - mwina chifukwa malo owuma sanawadyetsenso. Mikangano yachiwawa imayamba chifukwa chazinthu zina zomwe zimakulitsa vutoli. Mwachitsanzo, boma la Assad limadula ndalama zothandizira zakudya zamtundu uliwonse. Idalembetsa ku mfundo zandale zosasangalatsa zomwe zidasiya omwe akhudzidwa ndi chilala kuti azidzisamalira popanda thandizo la boma. "Kusintha kwanyengo kwatsegulira khomo laku gehena ku Syria", a Purezidenti wakale wa US Al Gore ndi Barack Obama adawunika nkhondo itayamba: "Chilala, kulephera kwa mbewu ndi chakudya chamtengo wapatali zidathandizira kuyambitsa mkangano woyambirira."

Komanso madera ena padziko lapansi , makamaka mdera la Sahel, kutentha kwa dziko kukuwonjezera mikangano. Chifukwa chimodzi china choyimira.
