The Impact of Climate Change on High - Altitude Lichens | CBCGDF Climate Change Working Group

High - altitude lichens, the slow - growing organisms that cling to rocks and trees in mountainous regions, are facing significant challenges due to climate change.

Lichens are a unique combination of fungi and algae or cyanobacteria, living in a symbiotic relationship. They are extremely sensitive to changes in temperature, humidity, and air quality. As global temperatures rise, the delicate balance of their habitats is being disrupted.

 

In high - altitude areas, the increase in temperature is causing a shift in the optimal growing conditions for lichens. Some species that are adapted to colder temperatures may struggle to survive as their habitats warm up. Additionally, changes in precipitation patterns can lead to drought stress or excessive moisture, both of which can be harmful to lichens.

 

Air pollution, which can be exacerbated by climate - related factors such as wildfires and changes in wind patterns, also poses a threat. Lichens absorb nutrients and pollutants directly from the air, and increased levels of pollutants can damage their cells and disrupt their metabolic processes. Studying and protecting high - altitude lichens is important. They serve as indicators of environmental change, and their decline could signal broader ecological problems in mountain ecosystems. Conservation efforts should focus on reducing air pollution, protecting their habitats from human encroachment, and understanding how they can adapt to the changing climate.

The 2024 World Water Forum Opens in Indonesia's Bali

Image
The 2024 World Water Forum (10th WWF) under the theme of "Water for Shared Prosperity" officially opened on Indonesia's island of Bali on Monday. This year ’ s theme emphasizes the need to work together to promote efficient and integrated water resources management to common prosperity. The 10th WWF ’ s six subthemes are: Water Security and Prosperity; Water for Humans and Nature; Disaster Risk Reduction and Management; Governance, Cooperation and Hydro-diplomacy; Sustainable Water Finance; and Knowledge and Innovation. This year, the Forum is expected to host 350 sessions, and receive 100,000 participants and visitors, 56 ministers, 12 heads of state, and about 2,000 journalists. The 10th World Water Forum focuses on four topics, namely water conservation, clean water and sanitation, food and energy security, and mitigation of natural disasters. The 10th WWF   is jointly organized by the Government of the Republic of Indonesia and the World Water Council. The Forum is th...

Unveiling the Mysteries of Cetaceans in the South China Sea: Chinese Scientists Describe Important Marine Mammal Areas (IMMAs)

Image
The world’s ocean ecosystems are facing mounting threats—climate change, marine pollution, overfishing, and habitat destruction due to human activities, to name a few. These pressures are particularly dangerous for marine mammals like cetaceans, whose survival hinges on healthy habitats and stable populations. Yet, in regions like the South China Sea, where biodiversity is exceptionally high, little research has been done to understand the needs and habitats of cetaceans. This lack of data has left a gap in our knowledge and made it challenging to establish targeted conservation strategies. Recognizing this, Chinese scientists have now set out to fill these gaps and contribute essential data to inform future policy and management, aiming to protect these vulnerable species and support the objectives of the Kunming-Montreal Global Biodiversity Framework (GBF). In a landmark study published on October 8, 2024, in Biological Conservation, Dr. Li Songhai and his team from the Institute of...
