Climate Analytics

RegioCrop is an online tool that gives non-expert users simple access to crop yield projections for all African countries derived from state-of-the-art global crop models. This tool gives access to spatial patterns of relative change in crop yields at different levels of global average temperature warming and corresponding aggregated impacts at the country level for a selection of crops.

Evaluating the near and long-term role of carbon dioxide removal in meeting global climate objectives

For 1.5°C pathways with limited overshoot, most of the mitigation between now and 2030 should come from emissions reductions (70%), with reductions from cutting non-CO2 emissions (20%) and land-based carbon dioxide removals such as afforestation and preventing deforestation (10%) making up the remainder.

Increasing April-May rainfall, El Niño and high vulnerability behind deadly flooding in Afghanistan, Pakistan and Iran

This April and May, large regions of central Asia were hit by a series of storms resulting in heavy downpours and flash flooding. Researchers assessed what extent human-induced climate change altered the likelihood and intensity of the weather conditions that caused the floods.

A review of loss and damage in the Caribbean (1994 to 2024)

Loss and damage from climate change has been the lived reality of Caribbean small island developing states (SIDS) for decades. Despite efforts to adapt, it is reversing development gains, leaving lasting financial stress, and causing irreparable damage, including the loss of cultural heritage. This report is the first to provide a systematic overview of how Caribbean countries are framing and reporting on loss and damage.

Earth Virtualisation Engines (EVE)

The authors propose creating an international federation of research institutions that improve the quality and accessibility of Earth systems data. The purpose is to empower all people to respond to the immense and urgent challenges posed by climate change.

Heavy precipitation hitting vulnerable communities in the UAE and Oman becoming an increasing threat as the climate warms

Researchers have assessed the extent human-induced climate change altered the likelihood and intensity of the weather conditions that caused the flooding in the United Arab Emirates and the northern parts of Oman in April 14–15 2024. The region was hit by exceptionally heavy rainfall causing massive disruption in infrastructure and public life in the area and leading to at least 20 fatalities in Oman and four in the UAE.

The impacts of multiple tropical cyclone events and associated precipitation on household income and expenditures

Climate change-fueled tropical cyclones have already reduced household incomes across the Philippines by 7% on average, according to a new study. This figure rises to more than 20% in some provinces.

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.
