Il Super El Niño e il problema più grande
James Hansen e colleghi pubblicano una nuova analisi sull'attuale El Niño, già più intenso di quello record del 1997-98. Ma il problema più grande resta l'accelerazione del riscaldamento globale, con impatti già oggi gravi sulle popolazioni più vulnerabili.
Il paradosso di Fermi
Una carrellata delle possibili soluzioni al famoso Paradosso di Fermi «se l'universo pullula di vita, ed una percentuale ragionevole di quella vita ha sviluppato una tecnologia avanzata, allora dove sono?»
Sesto rapporto di valutazione IPCC
L'IPCC è ora nel suo sesto ciclo di valutazione dell'evoluzione dei cambiamenti climatici. Verranno pubblicati a breve il sesto rapporto di valutazione (AR6) con i contributi dei suoi tre gruppi di lavoro ed un rapporto di sintesi, tre rapporti speciali ed un perfezionamento del suo ultimo rapporto metodologico. Analizziamo il primo documento pubblicato.
Geo-ingegnerizzazione del clima
A mali estremi estremi rimedi. Negli ultimi anni a fronte di cambiamenti del clima senza precedenti, sono state proposte alcune soluzioni rischiose per porre fine alla catena dei disastri climatici, o almeno per tentare di rallentarne la sua corsa. Questi metodi, raggruppati sotto il titolo di geo-ingegneria del clima, mirano a ridurre l'impatto dei gas serra sulle temperature globali.
Approvvigionamento energetico ed energie rinnovabili
I risultati accumulati negli ultimi decenni hanno reso estremamente chiaro come il modello attuale di generazione dell'energia non abbia futuro. Finitezza delle risorse di energia fossile, incidenti e disastri nucleari, impatto sulla salute, cambiamenti climatici. Fortunatamente una soluzione esiste, le energie rinnovabili. Anche se indubbiamente una completa conversione a queste fonti energetiche richiederà un considerevole sforzo politico, sociale, tecnologico ed una grande inventività.
Misura del Riscaldamento Globale
Sono disponibili numerose basi dati di misure delle temperature terrestri, ragionevolmente complete, e fin dalla seconda metà del XIX secolo. Il Met Office Hadley Centre in collaboratione con il Climatic Research Unit dalla University of East Anglia ha rilasciato a metà dicembre 2020 una nuova versione della base dati HadCRUT, che copre l'intero globo terrestre e contiene i dati mensili medi di ogni cella di controllo. In questo post visualizziamo questo dataset e calcoliamo una stima del riscaldamento globale attuale.
Fisica dei Cambiamenti Climatici
Una breve carrellata sulla fisica dei Cambiamenti Climatici utili a comprendere i fenomeni che sono alla base del clima, per rendere meno astratta una espressione ormai comunemente usata da tutti, e che costituisce un importante aspetto dei cambiamenti climatici: il riscaldamento globale.

My new website is born
Well. Finally got around to putting this website together. Powered by Jekyll, the Liquid template language, it supports HTML and markdown syntaxes in the posts. The layout is enriched by the usage of Bootstrap 4, Font Awesome, Google Fonts, and a few other optional JavaScript engines.
