Earth at risk: An urgent call to end the age of destruction and forge a just and sustainable future

PNAS Nexus, Journal Year: 2024, Volume and Issue: 3(4)

Published: March 28, 2024

Human development has ushered in an era of converging crises: climate change, ecological destruction, disease, pollution, and socioeconomic inequality. This review synthesizes the breadth these interwoven emergencies underscores urgent need for comprehensive, integrated action. Propelled by imperialism, extractive capitalism, a surging population, we are speeding past Earth's material limits, destroying critical ecosystems, triggering irreversible changes biophysical systems that underpin Holocene climatic stability which fostered human civilization. The consequences actions disproportionately borne vulnerable populations, further entrenching global inequities. Marine terrestrial biomes face tipping points, while escalating challenges to food water access foreshadow bleak outlook security. Against this backdrop Earth at risk, call response centered on decarbonization, fostering reciprocity with nature, implementing regenerative practices natural resource management.

Abstract. Global warming is amplified in the Arctic. However, numerical models struggle to represent key processes that determine Arctic weather and climate. To collect data help constrain models, HALO–(𝒜𝒞)3 aircraft campaign was conducted over Norwegian Greenland seas, Fram Strait, central Ocean March April 2022.

Harnessing human and machine intelligence for planetary-level climate action

npj Climate Action, Journal Year: 2023, Volume and Issue: 2(1)

Published: Aug. 17, 2023

Abstract The ongoing global race for bigger and better artificial intelligence (AI) systems is expected to have a profound societal environmental impact by altering job markets, disrupting business models, enabling new governance welfare structures that can affect consensus climate action pathways. However, the current AI are trained on biased datasets could destabilize political agencies impacting change mitigation adaptation decisions compromise social stability, potentially leading tipping events. Thus, appropriate design of less system reflects both direct indirect effects societies planetary challenges question paramount importance. In this paper, we tackle data-centric knowledge generation in ways minimize AI. We argue need co-align with an epistemic web health more trustworthy decision-making. A human-in-the-loop be designed align three goals. First, it contribute supports action. Second, directly enable interventions through elements. Finally, reduce data injustices associated pretraining datasets.
