The Double Crisis: Climate & Biodiversity

on YouTube ↗18m

" summary

Global temperature reaches 1.2°C and models project ~2.7°C on current pathways while the planetary boundaries framework and IPCC/IPBES syntheses show six of nine boundaries exceeded; intact ecosystems currently absorb roughly 0.4°C of warming so loss of nature accelerates climate risk. Empirical claims: protect 50% of nature to keep buffering capacity, Amazon now a net carbon source in parts, and 70% vertebrate decline since 1970. Observed warming rate jumps from 0.18 to 0.26°C/decade since 2014, implying degraded resilience and higher tipping risks.
