CRISE ECOLÓGICA, CAPITALISMO, ALTERMUNDIALISMO: UM PONTO DE VISTA ECOSSOCIALISTA
Bibliographic record
Abstract
Crise ecologica e mudanca climatica A crise ecologica planetaria atingiu um ponto de inflexao decisivo com o fenomeno da mudanca climatica. Primeira constatacao: tudo se acelera muito mais rapido que o previsto. A acumulacao de gas carbonico, o aumento da temperatura, o derretimento das geleiras polares e das ‘neves eternas’, as secas, as inundacoes: tudo se precipita, e as analises dos cientistas, cuja tinta mal secou nos documentos, se revelam muito otimistas. Pende-se agora, cada vez mais, para extremos os mais elevados, nas previsoes para os dez, vinte, trinta proximos anos. A isto, e necessario acrescentar alguns perigos, ainda pouco estudados, mas que arriscam provocar um salto qualitativo no efeito estufa e uma derrapagem incontrolavel no aquecimento do planeta. Por exemplo, os 400 bilhoes de toneladas de CO 2 aprisionadas, neste momento, no permafrost , essa tundra congelada que se estende do Canada a Siberia. Se as geleiras comecarem a derreter, por que o permafrost nao derreteria tambem? Existem poucos cenarios piores, caso a temperatura aumente 2 ou 3 graus. Os cientistas evitam delinear quadros catastroficos, mas ja sabemos os riscos aqui implicados: subida do nivel do mar, com inundacoes, nao somente de Daca e outras cidades maritimas asiaticas, mas tambem de Londres e Nova York. Desertificacao de terras a uma escala gigantesca. Falta de agua potavel. Catastrofes ‘naturais’ (tornados, tsunamis etc.) em serie. Poderiamos alongar a lista. A partir de certo nivel de temperatura – seis graus, por exemplo – a terra ainda sera habitavel para a nossa especie? Infelizmente, nao dispomos, neste momento, de um planeta sobressalente no universo conhecido dos astronomos.(...)

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
