Climate change is speeding up glacier melt and reducing snow cover in Central Asia, potentially creating glacial lakes that pose risks to mountain communities. A researcher from Germany's GFZ Center for Geoscientific Research highlighted these changes and their consequences at an international conference in Tashkent.

Eighteen participants from 13 African countries have completed an international geoscientific mapping training course in Namibia. Participants came from Botswana, Cameroon, Congo, Ghana, Kenya, Madagascar, Mozambique, Namibia, Nigeria, São Tomé and Príncipe, Eswatini, Zambia, and Zimbabwe. The 26-day training focused on skills in geological mapping such as field data collection, geological structures, geochemistry, geophysics, and remote sensing. The leader of PanAfGeo, Prague Stedra, said the training was to assist participants with field practical exercise. “This was training in geoscientific field mapping. We trained geologists from different African geological surveys to further develop their field-mapping skills, which are very important for every geological survey. These skills are essential for gaining control and context of the different elements connected with the geology of their respective countries.” Fieldwork was conducted in northern Namibia around Epupa, Swartbooisdrift, and Opuwo. The training was conducted by the Geological Survey of Namibia and geological institutions from Europe and Africa, with support from the European Union. Some of the participants described the training as informative. “Some of these vital skills, such as taking structural readings and identifying different rock types that you may not have in your country, tend to be forgotten. So, this training presented such an opportunity. Namibia has a vast geological setting that can provide us with all different types of rocks. In that way, we were able to refresh our skills,” said Vincent Lekula. “I understood why remote sensing is important, including why you need to understand your marks, how to interpret them, and when to apply that knowledge before going into any field-mapping experience. This involves a lot of data interpretation and understanding why you want to conduct field mapping in the first place,” added Elizabeth Akinyi.

The highest warming scenario used by climate modellers has fallen to 3.3C by 2100 from 4.6C, the first time the top of the range has come down in four generations of modelling, Carbon Brief reported on September 1. The seven new scenarios belong to the Coupled Model Intercomparison Project's seventh phase, CMIP7, which will feed the Intergovernmental Panel on Climate Change's seventh assessment. They were published in Geoscientific Model Development in April 2026 and the underlying emissions data was released on September 1. For anyone financing energy assets with a 25-year life, the change at the top of the range is commercially relevant. The scenarios that banks and insurers have been running as their stress case were built on an assumption of coal-led growth and costly renewables, and the modellers have now written that future off as implausible. What changed The old high-emissions pathways "have become implausible, based on trends in the costs of renewables, the emergence of climate policy and recent emission trends", according to the study Carbon Brief cites. The numbers behind that judgement are large. The new high scenario carries cumulative CO2 emissions of 3,820 GtCO2 between 2024 and 2100, against roughly 7,600 GtCO2 in SSP5-8.5, the highest scenario of the previous generation. The worst case has been halved. Four other things changed with it. The scenarios are named by emissions trajectory rather than by radiative forcing. There is no longer a no-climate-policy scenario, the range instead running from current policies weakening to current policies strengthening. The models now calculate atmospheric CO2 concentrations from emissions rather than having concentrations prescribed. And the runs extend to 2150, with extensions to 2500, rather than stopping at 2100. The socioeconomic assumptions were revised in 2024 towards higher population and lower income per capita. Global population in 2100 under the middle pathway is now put at 9.9bn, a billion higher than before, with income per capita 10% to 25% lower than the original assumptions across most scenarios. The seven scenarios The high scenario reaches 3.3C by 2100, with a range of 2.6C to 4.4C. Medium, which freezes current policies at 2025 levels, reaches 2.9C. High-to-low, which runs high to mid-century then reaches net zero CO2 by 2100, gives 2.8C. Medium-low gives 2.3C. At the bottom, low reaches 1.8C, low-to-negative 1.7C and very-low 1.6C. Only those last three are consistent with the Paris temperature goals, and all three require carbon removal at industrial scale. Cumulative removals to 2150 run from 655 GtCO2 in the very-low scenario to 2,360 GtCO2 in low-to-negative. In that last case about 1,750 GtCO2 of engineered removal, from bioenergy with carbon capture and from direct air capture, would need geological storage by 2150. Cutting the top of the range does not move the near-term problem. On the medium scenario, which is the one that assumes today's policies simply continue, 1.5C is essentially locked in by the late 2020s or early 2030s and 2C is crossed around 2050. It takes until about 2110 to reach 3C, and there is a one-in-four chance of 4C by 2150. The comparison across generations shows how far the ceiling has moved. SRES A1FI gave 4.6C in 2100, RCP8.5 gave 4.9C and SSP5-8.5 gave 4.6C. CMIP7's high gives 3.3C. The first model runs took place in the spring of 2026 and initial results are expected later this year.
