Klimatski kolaps na Arktiki! Tokrat se je resnično vse obrnilo!! (YouTube – 23. februar 2025)

25. februarja, 2025
| Ni komentarjev
| Spletni mediji - Web media

Video prispevek (11:14) na YouTube kanalu Just Have a Think obravnava vznemirljivo pospeševanje globalnega segrevanja, ki presega prejšnje znanstvene napovedi in podnebne cilje. Avtor izpostavlja nove podatke, po katerih je tretjina Arktike postala vir ogljika namesto njegovega ponora, kar sproža nevarne povratne zanke. Kritika je usmerjena proti politični pasivnosti in zanašanju na neobstoječe tehnologije, ki bi domnevno odstranile presežni […]

Poročilo o Arktiki za leto 2024: Arktična tundra je zdaj neto vir ogljikovega dioksida (Climate.gov – 10. december 2024)

| Spletni mediji - Web media

Details (podrobnosti): Glede na poročilo NOAA o Arktiki za leto 2024 je arktična tundra postala vir ogljikovega dioksida in metana v ozračju, kar je posledica kombinacije mikrobne aktivnosti v taljenju permafrosta in emisij iz gozdnih požarov, ki so vse pogostejši. Leta 2024 so bile temperature permafrosta najvišje v zgodovini na skoraj polovici dolgoročnih merilnih postaj […]

Na tisoče grenlandskih ledenikov se hitro krči. Fotografije pred in po razkrivajo desetletja sprememb (CNN Climate – 13. november 2023)

Prispevek na spletnem podtalu CNN Climate poroča o zaskrbljujočem umikanju grenlandskih ledenikov. Raziskovalci so primerjali stare zračne posnetke iz 30. let prejšnjega stoletja s sodobnimi satelitskimi slikami. Ugotovili so, da se je umikanje ledenikov v 21. stoletju podvojilo v primerjavi z 20. stoletjem. Študija poudarja, da se Arktika segreva štirikrat hitreje od preostalega sveta, kar povzroča dramatične posledice za dvig […]
