Mitigation, pledges, impacts and effects on Least Developed Countries

Authors

Michiel Schaeffer, Felix Fallasch, Sandra Freitas, Andries Hof, Kirsten Macey, Joeri Rogelj, Bill Hare

This paper shows that ambitious global greenhouse gas mitigation action in a transparent and effective international climate regime is of great importance to Least Developed Countries. Through such ambitious global mitigation, impacts and damage to LDCs can be limited, and financial and technological flows can be generated from developed to developing countries.

Mapping the climate risk to urban forests at city scale

This study uses an urban tree inventory and high-resolution climate projections to identify species and locations at risk from climate change in Melbourne. It finds that half of the tree species in Melbourne are at risk from heat stress, which could climb to two thirds in 2050.

The 1.5°C limit and risks of overshoot

This briefing looks at what the 1.5°C limit means in terms of adaptation and loss and damage for the most vulnerable countries and regions. It finds that slowing down warming is critical to buy us time to adapt and also to avoid irreversible loss and damage. Even if warming rises above 1.5°C (overshoot) we can bring it down again with ambitious emissions reductions.

Hydrologic interpretation of machine learning models for 10-daily streamflow simulation in climate sensitive upper Indus catchments

This study augments physical hydrological modeling with machine learning models to simulate surface water flows in Upper Indus water catchments in Pakistan.

Le seuil de +1,5°C et le risque de dépassement de ce seuil

Ce rapport examine ce que la limite de 1,5 °C signifie en termes d'adaptation et de pertes et dommages pour les pays et régions les plus vulnérables. Il constate qu'il est essentiel de ralentir le réchauffement pour nous donner le temps de nous adapter et pour éviter des pertes et des dommages irréversibles. Même si le réchauffement dépasse 1,5 °C, nous pouvons le faire baisser à nouveau en réduisant les émissions de manière ambitieuse.

Representing natural climate variability in an event attribution context: Indo-Pakistani heatwave of 2022

New study finds that the 2022 Indo-Pakistani heatwave was both more likely to occur and more intense due to increasing global warming – even when accounting for the effects of natural climate variability and the forced response to anthropogenic climate change.

Extreme terrestrial heat in 2023

Multiple relentless heatwaves occurred in 2023, with much of the world experiencing at least 20 more heatwave days than the 1991–2020 average. This study looks at prominent and record-breaking events around the world.

Climate impacts in northern forests

Northern forests hold around 54% of the world’s total terrestrial carbon stock and contribute more than one-third to our global terrestrial carbon sink. This report reviews the impact of human induced climate change on northern temperate and boreal forests.

Effects of idealised land cover and land management changes on the atmospheric water cycle

This study investigates how land cover and land management affects atmospheric moisture transport using global climate models. It finds that cropland expansion is generally causing a drying and reduced local moisture recycling, while afforestation and irrigation expansion generally cause wetting and increased local moisture recycling.

Effectiveness of water-related adaptation decreases with increasing warming

When it comes to water, adaptation to climate change becomes less effective when warming is above 1.5°C, according to a new study looking at water-related climate risk at 1.5°C, 2°C, 3°C, and 4°C of warming. The study finds adaptation needs to go hand-in-hand with ambitious emissions reductions and decarbonisation.

A better integration of health and economic impact assessments of climate change

This study lays out how to integrate the economic repercussions of climate change on people's health with direct health impacts. The authors argue this could provide more realistic scenario projections than health studies on their own and be more useful for adaptation policy.

Tripling renewables by 2030: interpreting the global goal at the regional level

At COP28, governments agreed to triple global renewable capacity by 2030. This report breaks down what a 1.5ºC-aligned renewables rollout would look like at the regional level and calculate the associated investment needs.

Submission to the Australian Treasury consultation on the Petroleum Resource Rent Tax

As the gas industry in Australia has grown exponentially, the profit taxes it pays to the government have proportionally plummeted, presenting an opportunity to change this regime. Here, we respond to the Australian Government Treasury consultation on the Petroleum Resource Rent Tax (PRRT) – anti-avoidance provisions and clarifying treatment of ‘exploration’ and Mining, Quarrying or Prospecting Rights.
