Climate science demands automated workflows to transform comprehensive questions into data-driven statements across massive, heterogeneous datasets. However, generic LLM agents and static scripting pipelines lack climate-specific context and flexibility, thus, perform poorly in practice. We present ClimateAgent, an autonomous multi-agent framework that orchestrates end-to-end climate data analytic workflows. ClimateAgent decomposes user questions into executable sub-tasks coordinated by an Orchestrate-Agent and a Plan-Agent; acquires data via specialized Data-Agents that dynamically introspect APIs to synthesize robust download scripts; and completes analysis and reporting with a Coding-Agent that generates Python code, visualizations, and a final report with a built-in self-correction loop. To enable systematic evaluation, we introduce Climate-Agent-Bench-85, a benchmark of 85 real-world tasks spanning atmospheric rivers, drought, extreme precipitation, heat waves, sea surface temperature, and tropical cyclones. On Climate-Agent-Bench-85, ClimateAgent achieves 100% task completion and a report quality score of 8.32, outperforming GitHub-Copilot (6.27) and a GPT-5 baseline (3.26). These results demonstrate that our multi-agent orchestration with dynamic API awareness and self-correcting execution substantially advances reliable, end-to-end automation for climate science analytic tasks.

For a long time, many climate scientists and advocates held onto an optimistic belief that once the impacts of climate change became undeniable, people and governments would act. But whereas the predictions of climate models have increasingly borne out, the assumptions about human behavior have not. Even as disasters mount, climate change remains low on voters' priority lists, and policy responses remain tepid. To me, this gap reflects a deeper failure--not just in policy or communication, but in how we understand human adaptability. When I began my career as a computational cognitive scientist, I was drawn to a defining strength of human cognition--a marked ability to adapt.

A House Oversight Committee hearing produced a flood of bizarre claims about cloud seeding, chemtrails, and solar geoengineering. Proven, human-driven changes to the weather were dismissed. "What this whole debate comes down to is who controls the skies," Republican representative Marjorie Taylor Greene of Georgia told the audience at a House Oversight Committee hearing on Tuesday. "Do we believe in God and that he has dominion over his perfect creation of planet Earth? Do we believe that he has given us everything we need to survive as a civilization since the beginning of time? Or do you believe in man's claim of authority over the weather, based on scientists that have only been alive for decades and weren't here to witness the climate changes since the beginning of time?"

The growing complexity and volume of climate science literature make it increasingly difficult for researchers to find relevant information across models, datasets, regions, and variables. This paper introduces a domain-specific Knowledge Graph (KG) built from climate publications and broader scientific texts, aimed at improving how climate knowledge is accessed and used. Unlike keyword based search, our KG supports structured, semantic queries that help researchers discover precise connections such as which models have been validated in specific regions or which datasets are commonly used with certain teleconnection patterns. We demonstrate how the KG answers such questions using Cypher queries, and outline its integration with large language models in RAG systems to improve transparency and reliability in climate-related question answering. This work moves beyond KG construction to show its real world value for climate researchers, model developers, and others who rely on accurate, contextual scientific information.

Hosted by Ben Byford, The Machine Ethics Podcast brings together interviews with academics, authors, business leaders, designers and engineers on the subject of autonomous algorithms, artificial intelligence, machine learning, and technology's impact on society. This is our 100th episode! A super special look at AI and the environment, we interviewed four experts for this DeepDive episode. We chatted about water stress, the energy usage of AI systems and data centres, using AI for fossil fuel discovery, the geo-political nature of AI, GenAI vs other ML algorithms for energy use, demanding transparency on energy usage for training and operating AI, more AI regulation for carbon consumption, things we can change today like picking renewable hosting solutions, publishing your data, when doing "responsible AI" you must include the environment, considering who are the controllers of the technology and what do they want, and more… Hannah Smith is Director of Operations for Green Web Foundation and co-founder of Green Tech South West.

In recent years, foundation models have attracted significant interest in climate science due to their potential to transform how we approach critical challenges such as climate predictions and understanding the drivers of climate change [Thulke et al., 2024, Nguyen et al., 2024, Cao et al., 2024]. However, while these models are powerful, they often fall short when it comes to answering technical questions requiring high precision such as What is the net effect of Arctic stratus clouds on the Arctic climate? Even advanced models like GPT-4 exhibit epistemological inaccuracies in Climate Question-Answering (QA) tasks [Bulian et al., 2024], raising concerns about their reliability in scientific workflows. This highlights the need for a domain-specific evaluation framework to assess the quality and validity of outputs generated by these models. Current benchmarks for Large Language Models (LLMs) predominantly focus on linguistic accuracy or general factual correctness, but they fail to address the unique demands of climate science, where factual rigor, domain-specific knowledge, and robust reasoning are essential.

Detecting and attributing temperature increases due to climate change is crucial for understanding global warming and guiding adaptation strategies. The complexity of distinguishing human-induced climate signals from natural variability has challenged traditional detection and attribution (D&A) approaches, which seek to identify specific "fingerprints" in climate response variables. Deep learning offers potential for discerning these complex patterns in expansive spatial datasets. However, lack of standard protocols has hindered consistent comparisons across studies. We introduce ClimDetect, a standardized dataset of over 816k daily climate snapshots, designed to enhance model accuracy in identifying climate change signals. ClimDetect integrates various input and target variables used in past research, ensuring comparability and consistency. We also explore the application of vision transformers (ViT) to climate data, a novel and modernizing approach in this context. Our open-access data and code serve as a benchmark for advancing climate science through improved model evaluations.

Imagine if the world's response to climate change relied solely on speculative predictions from pundits and CEOs, rather than the rigorous--though still imperfect--models of climate science. "Two degrees of warming will arrive soon-ish but will change the world less than we all think," one might say. "Two degrees of warming is not just around the corner. This is going to take a long time," another could counter. This is more or less the world we're in with artificial intelligence, with OpenAI CEO Sam Altman saying that AI systems that can do any task a human can will be developed in the "reasonably close-ish future," while Yann LeCun, Chief AI Scientist at Facebook, argues that human-level AI systems are "going to take a long time."

Africa, with its diverse ecosystems and rich natural heritage, is not just a continent; it's a tapestry of vibrant cultures deeply intertwined with the environment. From the lush rainforests of the Congo Basin, serving as the planet's lungs, to the Sahara Desert's arid expanses, the beauty and uniqueness of Africa's ecosystems are a source of pride and integral to the African way of life. However, like all others, we as a continent face the imminent threat of climate change, which poses challenges that demand people-centric and context-aware solutions. Against this backdrop, AfriClimate AI, a grassroots community, was born with the vision to harness the power of Artificial Intelligence (AI) for a sustainable, prosperous, and climate-resilient Africa. The idea for AfriClimate AI emerged in September 2023 at the Deep Learning Indaba, Africa's largest annual gathering of AI researchers that took place in Accra, where we collectively realised the many opportunities for community-driven AI efforts in addressing this imminent threat.

These authors contributed equally to this work. Abstract Foundation models have enormous potential in advancing Earth and climate sciences, however, current approaches may not be optimal as they focus on a few basic features of a desirable Earth and climate foundation model. Crafting the ideal Earth foundation model, we define eleven features which would allow such a foundation model to be beneficial for any geoscientific downstream application in an environmental-and human-centric manner. We further shed light on the way forward to achieve the ideal model and to evaluate Earth foundation models. What comes after foundation models? Energy efficient adaptation, adversarial defenses, and interpretability are among the emerging directions. In the past decade in particular, we have witnessed a paradigm shift from single-purpose models to general-purpose models, and from supervised pre-training to self-supervised pre-training. The majority of FMs like CLIP and GPT focus on the image and text domains. In this work, we specifically focus on "data" and "downstream tasks" relating to the Earth and its climate system, as shown in Figure 1. We choose to limit the scope of our work to the Earth's surface and atmosphere for three reasons. First, the Earth's surface and troposphere are our home, and include the majority of processes that directly impact and are impacted by human activity.
