Quantifications of the impacts of sea-level rise in small island states are urgently needed. Focusing on flooding from sea-level rise, a study now estimates the impacts in terms of cost, land loss and population exposure across all small islands worldwide.
However, for many islands, quantitative assessments of climate change impacts at the national level are still lacking. Writing in Nature Sustainability, Vousdoukas et al. fill this gap through a global quantitative assessment of the direct impacts from sea-level rise (SLR) on the people, land and economies of SIDS. Their study shows in grim clarity the unavoidable impacts of SLR for SIDS even under a 1.5 °C scenario, but also underscores what negative impacts can still be avoided if urgent climate action is taken.
Carbon majors’ trillion dollar damages
In this report we explore who could pay for loss and damage through the lens of responsibility for historic emissions, and the financial gains generated from selling oil and gas.
The effects of political knowledge use by developing country negotiators in Loss and Damage negotiations
This article traces how developing country negotiators used knowledge to further their interests in loss and damage negotiations from 2003 to 2013.
Research agenda for the loss and damage fund
This piece in Nature discusses what research could contribute to the design of the loss and damage fund.
The deployment length of solar radiation modification: an interplay of mitigation, net-negative emissions and climate uncertainty
Here, we investigate the deployment timescales of solar radiation modification and how they are affected by different levels of mitigation, net-negative emissions and climate uncertainty.
Emissions as usual: implications for the Safeguard Mechanism of LNG and coal mine projects
This report examines the implications of committed and proposed developments in the LNG and coal mining sectors for reform of Australia's Safeguard Mechanism.
Only halving emissions by 2030 can minimise risks of crossing cryosphere thresholds
Climate justice and loss and damage: Hurricane Dorian, Haitians and human rights
Haitian communities were the locus of the majority of deaths and missing people attributed to the 2019 Hurricane Dorian and faced a series of distributional, procedural and recognition injustices. We investigate the historical factors and contemporary conditions of Haitian communities in The Bahamas that resulted in significant inequities, disproportional impacts and infractions of human rights.
Institutional decarbonisation scenarios evaluated against the Paris Agreement 1.5°C goal
This study analyses six institutional decarbonisation scenarios published between 2020 and mid 2021 (including four from the oil majors and two from the International Energy Agency. It finds that most of the scenarios would be classified as inconsistent with the Paris Agreement as they fail to limit warming to ‘well below 2 ̊C, let alone 1.5 ̊C, and would exceed the 1.5 ̊C warming limit by a significant margin.
Uncertainty in near-term temperature evolution must not obscure assessments of climate mitigation benefits
This work comments on a study by Samset et al. that found the effects of emission mitigation will only be perceived through global temperature with a multi-decadal delay. This paper provides additional context and expresses concerns with the approach.
An emission pathway classification reflecting the Paris Agreement climate objectives
When categorising pathways in line with the Paris Agreement, the focus has been put on the temperature outcome. Here we propose a pathway based on emission reduction objectives that reflect the climate criteria set out in the Paris Agreement.
