Researchers at the University of Cape Town have shown that the warm Agulhas Current System supplies the heat and moisture that intensified a cut-off low storm over the Western Cape, driving the province’s most destructive floods. The findings highlight the ocean’s role in extreme rainfall and disaster risk management.

Planetary scientists Brandon Johnson and Alexandria Johnson studied the asteroid that struck Earth 66 million years ago, killing most of the dinosaurs. They discovered the impact swathed the planet in an insulating dust cloud that caused planetwide spontaneous combustion, atmospheric contamination and population collapse in any species that couldn’t take shelter.

A localized study in Tiaty, Kenya, shows how climate variability and land-use change are reshaping pastoral and agro-pastoral livelihoods. Using satellite imagery, climate records, agroecological information, and socioeconomic data, researchers found shifts in vegetation, rainfall seasonality, livestock choices, and settlement patterns. The findings highlight the need for locally tailored adaptation strategies that support resilient livestock systems, sustainable rangeland management, and climate-smart farming.

The most severe droughts in the ancient Eastern Mediterranean arose when multiple natural climate cycles coincided, according to a new study from Stockholm University published in Science Advances. The findings shed new light on the climate conditions surrounding the Late Bronze Age collapse and may help improve understanding of future drought risks in a warming world.

New research found that the century-old yardstick used across many industries to estimate air-conditioning and refrigeration energy demand — called cooling degree days — is missing something fundamental. The study reports a new, physics-based version of the metric — effective cooling degree days — that captures how temperature and humidity together impact the actual work a cooling system is required to do. Applying it across North America, they found that cooling efficiency has been quietly declining by 2–4% per decade since 1971, and that the old temperature-only metric misjudges how much cooling is required in different regions, overstating demand in some places and understating it in others.

A new international study published in Nature Food reveals that age plays an important but often overlooked role in shaping global food-related greenhouse gas emissions. Effective mitigation of dietary emissions therefore requires age-sensitive approaches.

As nations worldwide confront the urgent challenge of climate change, China's "Dual Carbon" goals prioritize significant decarbonization across all economic sectors. While industrial and energy sectors often receive primary attention, the agricultural sector, particularly livestock farming, represents a substantial source of potent greenhouse gases like methane (CH₄) and nitrous oxide (N₂O). Local governments in China have implemented stringent environmental regulations, such as "Livestock-Free Zones," to curb agricultural pollution. However, the overall effectiveness of these spatially targeted policies, especially regarding their potential to displace environmental burdens, remains a subject of considerable debate.

A recent study investigated the impacts of the "Livestock-Free Zone" policy in Guangdong Province, China's largest provincial economy. Researchers utilized county-level panel data from 2014 to 2023, employing a sophisticated combination of spatial Durbin models, continuous difference-in-differences models, and network analysis. This approach allowed for a precise quantification of the policy's local effects and any subsequent spatial spillover, addressing gaps in understanding policy-induced pollution transfers within land-intensive agricultural sectors and at subnational scales.
