Additionally, there is a notable increase in warm nights and days across almost the entire state, at a rate of +0.1 to +0.6% days per year. Rainfall trends show significant increases in annual totals in the Baixadas Litorâneas, with rates between +4.0 and +32.0 mm per year, as well as more frequent heavy rain events in this region and parts of the Metropolitan Region, ranging from +2.0 to +20 mm per year. The study analyzed observational data to characterize temperature and precipitation patterns, providing critical insights into climate change impacts on this UNESCO World Heritage Site.

A century of advocacy and adventure by the Alpine Club of Canada (ACC) has shaped the Canadian Rocky Mountain Parks into a 'climber's paradise,' blending human activity with wild spaces. PearlAnn Reichwein's research, rooted in mountaineering experience and mountain culture studies, presents a novel framework for understanding these landscapes as interconnected systems. By integrating environmental history, public policy, sport studies, recreation, and tourism, the study offers a multidisciplinary perspective that challenges conventional narratives of development versus preservation. This work not only contributes to academic fields but also resonates with mountaineers, environmentalists, and travelers, providing a nuanced lens through which to view Canada's natural heritage.
Mount Qingcheng and the Dujiangyan Irrigation System

A critical analysis of the Dujiangyan Irrigation System, a 2,268-year-old UNESCO-listed marvel, reveals that its Baizhang dike and Renzi dike play pivotal roles in flood control and sediment management. Contrary to earlier assumptions, the Fish Mouth does not automatically regulate water diversion; instead, upstream reaches govern flow patterns during floods and dry seasons. The Baizhang dike stabilizes the Min River's bed, preventing flooding while allowing driftwood entry into the Inner River during non-flood periods. Annual maintenance, traditionally performed by farmers in winter, ensures system stability by clearing sediment and adjusting weir structures like Feishayan to balance flood discharge and irrigation demands. Post-1992, maintenance intervals extended to every 10 years due to reduced upstream sediment influx and modern gate installations controlling Inner River flow.
Medina of Tunis

A North African feminist movement, rooted in Tunisia's Medina of Tunis, has emerged as a response to systemic gender inequality and the neglect of vulnerable women. Sana Ben Achour, a prominent activist and legal scholar, spearheaded efforts to amend Tunisia's Code of Personal Status, addressing issues like inheritance inequality and male-dominated parental authority. Her work extended beyond legislation, establishing the first support center for victims of violence and later founding a non-profit organization to aid homeless women, a marginalized group with no social safety net. The movement also confronts growing threats to reproductive rights, as religious influences deter healthcare professionals from providing abortion services, particularly to single women. This case study highlights the intersection of legal advocacy, grassroots activism, and urban space repurposing in advancing gender equality within a UNESCO World Heritage Site.
Yellowstone National Park

The vibrant colors observed in Yellowstone National Park's thermal pools are primarily shaped by microbial mats at the pool bottoms, with their spectral properties linked to water temperature. Deeper pools, however, derive their hues mainly from wavelength-dependent absorption and scattering within the water itself. Researchers used a 1D radiative transfer model to simulate these colors, incorporating data on water attenuation, microbial mat reflection, and surface reflection. The study also utilized thermal imaging to map water skin temperatures, confirming that shallow-water features' colors are dominated by microbial activity, while deeper pools exhibit color variations due to light interaction with the water column.
