This submission assesses which of the options proposed for the New Zealand government’s proposal for a Zero Carbon Bill are compatible with the Paris Agreement's long-term temperature goal.

Recent publications have argued that the remaining “carbon budget” available to meet the Paris agreement long-term temperature goal is larger than previously estimated in IPCC AR5. This briefing outlines why the notion of “more time” for climate protection is ill advised. We have no time to lose to achieve 1.5°C.

Indicators used to define limits of warming and those used to track the evolution of the Earth System under climate change are not directly comparable.

This article presents projections of future changes in aridity on small islands and evaluates overall changes in freshwater stress in small island developing states at warming levels of 1.5 and 2°C above pre-industrial level.

To support implementation of the Paris Agreement, the new HAPPI ensemble of 20 bias-corrected simulations of four climate models was used to drive two global hydrological models in worlds approximately 1.5 °C and 2 °C warmer than pre-industrial.
