California is facing a critical water supply shift as climate change depletes traditional snowmelt-fed reservoirs, leading to an increased reliance on groundwater. The document highlights that snow is melting up to 30 days earlier than in the mid-twentieth century and that the state's surface-water storage is not designed for a future of rain-dominant precipitation. This has led to the over-pumping of aquifers, particularly in the Central Valley. To address this, the document advocates for the implementation of the Sustainable Groundwater Management Act (SGMA) of 2014, which requires local agencies to develop sustainability plans by 2020. The authors propose capturing floodwaters to recharge aquifers, which would simultaneously reduce flooding risks and provide a buffer against future droughts.

The paper examines the climatic risks of nuclear war, updating the 'nuclear winter' concept with modern climate modelling. It argues that even a regional conflict or the deployment of a single UK Trident submarine could cause significant global cooling, disrupt agriculture, and lead to mass starvation. The author concludes that any arsenal exceeding 5MT poses a global climatic threat and calls for the cessation of the UK's Trident replacement programme.

The document asserts that methane emissions from the natural gas supply chain are significantly underestimated, potentially making gas power more harmful to the climate than coal if leakage rates exceed 3%. For Japan, which imports over 90% of its gas as LNG, this creates both climate risks and energy security vulnerabilities. The briefing advocates for a transition away from gas through policies such as phasing out fossil fuel subsidies, prioritizing grid infrastructure for electrification and renewables, simplifying permitting for renewables, and implementing Carbon Contracts for Difference (CfD).

The report critiques the Indonesian government's strategy of using natural gas as a 'bridge' fuel, specifically focusing on planned gas infrastructure in Bali, including a Floating Storage Regasification Unit (FSRU) and several gas power plants (PLTG). It argues that gas is not a clean energy source due to methane leaks and carbon emissions, which contribute to the extreme weather and water crises already affecting Bali. The document highlights social and environmental damages from existing gas projects, such as the PLTGU Pemaron, and argues that Bali's significant renewable energy potential—estimated up to 26 GW—should be prioritized over fossil fuels to achieve true energy independence and climate resilience.
