Irreversible glacier change and trough water for centuries after overshooting 1.5 °C | Nature Climate Change

Exceeding 1.5 °C of global warming above pre-industrial levels has become a distinct possibility, yet the consequences of such an overshoot for mountain glaciers and their contribution to raising sea levels and impacting water availability are not well understood. Here we show that exceeding and then returning to below 1.5 °C will have irreversible consequences for glacier mass and runoff over centuries. Global climate and glacier simulations project that a 3.0 °C peak-and-decline scenario will lead to 11% more global glacier mass loss by 2500 compared with limiting warming to 1.5 °C without overshooting. In basins where glaciers regrow after peak temperature, glacier runoff reduces further than if the glaciers stabilize, a phenomenon we call ‘trough water’. Half the studied glaciated basins show reduced glacier runoff with overshoot compared with without for decades to centuries after peak warming. These findings underscore the urgency of near-term emissions reductions and limiting temperature overshoot. (date: 07/07/2026)

Peak glacier extinction in the mid-twenty-first century | Nature Climate Change

Projections of glacier change typically focus on mass and area loss, yet the disappearance of individual glaciers directly threatens culturally, spiritually and touristically significant landscapes. Here, using three global glacier models, we project a sharp rise in the number of glaciers disappearing worldwide, peaking between 2041 and 2055 with up to ~4,000 glaciers vanishing annually. Regional variability reflects differences in average glacier size, local climate, the magnitude of warming and inventory completeness. (date: 07/07/2026)

Glacier melt trough after overshoot | Nature Climate Change

Glaciers are retreating under climate change and generating excessive meltwater. A modelling study shows that regrowing glaciers may lead to water scarcity in the centuries after overshooting the +1.5 °C temperature target. Glaciers are important for water supply in large parts of the world. In the field of glacio-hydrology, ‘peak water’ is a commonly known concept. This concept indicates that glacier wastage due to climate change initially increases meltwater production, reaching a peak at a certain point. However, as glacier loss continues, the meltwater supply to downstream eventually declines. However, understanding of the future of glaciers and their meltwater under overshoot and stabilization scenarios is lacking. Writing in Nature Climate Change, Lillian Schuster, Fabien Maussion and co-authors1 report that overshoot leads to the phenomenon of ‘trough water’, which may happen centuries in the future.

The Land Use Framework for England (accessible) - GOV.UK

Land is our greatest natural asset and the foundation of our lives. The landscapes of England are the product of centuries of changing use, the source of our food, home to the ecosystems that sustain life, and the foundation of a growing economy. How we decide to use that land in the decades ahead will shape everything: the homes our children live in, the energy that powers our economy, the nature we pass on to future generations.

UK’s 2024 Food Security Report

The impacts of climate change, biodiversity loss and water insecurity both at home and abroad remain pressing risks to food security. They drive volatility in the present and put sustainability and resilience of food production at risk over the longer term. These risks are also now interacting with heightened geopolitical tensions. Labour shortages in key sectors at home are also a continuing stress factor affecting domestic food production. (date: 07/07/2026)

Mapped: How extreme weather is destroying crops around the world

“Sudden food production losses” due to extreme weather events have become increasingly frequent “since at least [the] mid-20th century”, according to the sixth assessment report (AR6) from the Intergovernmental Panel on Climate Change (IPCC). The report found with high confidence that extreme weather events will push some current food-growing areas “beyond the safe climatic space for production”. Experts tell Carbon Brief they are concerned about how repeated and intensifying extremes will impact agriculture around the world. (date: 07/07/2026)

Data Centres Emitting More CO2 Than Thought: Study - Barron's

From Mike T: "An interesting report from Allianz Trade, highlighting that data centres power consumption and emissions are likely to be 50% more than that already predicted by the Intl. Energy Agency. Being an insurance company, with an eye to the impacts of acelerating climate change, they have an interest in getting these figures right." (date: 06/07/2026)
