1. Padziko lonse lapansiCO2Yafika Pamwamba Kwambiri — Koma Musachite Mantha: Mpweya Wamkati Ukadali Wosasinthika
Malinga ndiNkhani Yokhudza Mpweya Wotentha ya Bungwe la Padziko Lonse la Zanyengo (WMO), Okutobala 15, 2025, mpweya wa CO2 padziko lonse lapansi wafika pamlingo wapamwamba kwambiri m'mbiri424 ppm mu 2024, kukwera3.5 ppm m'chaka chimodzi— kulumpha kwakukulu kuyambira mu 1957.
Zingamveke ngati zowopsa pang'ono, koma musasokoneze mfundo ziwirizi.

Ngakhale kuti CO2 ikukwera padziko lonse lapansi,mpweya wabwino kapena njira zopumira mpweya wabwino zimatha kusokoneza m'nyumbaCO2milingo kuyambira 1,500 ppm mpaka pafupifupi 700–800 ppm, zomwe zimawonjezera kwambiri thanzi ndi zokolola.
2. WapamwambaCO2Sikukupatsa Poizoni — Kumakuchepetsani Mtima
Kafukufuku wa sayansi akusonyeza kuti:
| Mlingo wa CO2 | Mkhalidwe | Zotsatirapo pa Anthu |
| 400–800 ppm | Mpweya wabwino | Kuganiza bwino komanso kolunjika |
| 800–1200 ppm | Zodzaza pang'ono | Kugona, kusamvetsera kwambiri |

3. Mpweya wopumira ukugwirabe ntchito — Ndipo Ndi Wofunika Kwambiri Kuposa Kale Lonse
Ngakhale kuti CO2 ikukwera padziko lonse lapansi,mpweya wakunja ukadali woyerakuposa mpweya woipa wa m'nyumba. Mpweya wopuma umachita zambiri kuposa "kungosuntha mpweya."

6. Mafunso Ofunsidwa Kawirikawiri — Zimene Anthu Amafunsa Kawirikawiri
Q1: Ndi padziko lonse lapansiCO2Kodi mpweya wabwino kwambiri chonchi, udakali wofunikabe?
A: Inde. PanjaCO2≈ 424 ppm; kuchuluka kwa mpweya m'nyumba nthawi zambiri kumafika pa 1,500 ppm. Mpweya wabwino umabwezeretsa kuchuluka kotetezeka.
Q2: Kodi kutsegula mawindo kokwanira?
A: Mpweya wopumira wachilengedwe umathandiza, koma nyengo ndi kuipitsidwa kwa chilengedwe zimalepheretsa.Makina opangira mpweya wabwino ndi kuyang'anira ndi abwino kwambiri.
Q3: Kodi zotsukira mpweya zimachepetsaCO2?
A: Ayi. Zotsukira zimasefa tinthu tating'onoting'ono, osati mpweya.CO2ziyenera kuchepetsedwa ndi mpweya wokwanira kapena zomera.
Q4: Ndi mulingo uti "wokwera kwambiri"?
A: Yatha1,000 ppm zizindikiro za mpweya woipa;1,500 ppm zikutanthauza kuima kwakukulu.
Q5: Chifukwa chiyani masukulu ndi maofesi amakhazikitsaCO2zowunikira?
A: Malo odzaza ndi anthu ambiri, otsekedwa amasonkhanaCO2Kuwunika kosalekeza kumaonetsetsa kuti malo abwino komanso opindulitsa ali bwino.
