What are Geoengineering in Response to Climate Change | CBCGDF Climate Change Working Group

Geoengineering presents a set of potential solutions in the face of climate change. One approach is solar radiation management. For instance, the idea of injecting aerosols into the stratosphere to reflect a portion of the sun's radiation back into space has been proposed. This mimics the natural effect of volcanic eruptions, which release particles that can cool the planet. However, it also brings potential risks, such as disrupting weather patterns and affecting ozone levels.

Another aspect of geoengineering is carbon dioxide removal.

 

This includes techniques like afforestation on a large scale. Trees absorb carbon dioxide during photosynthesis, thus reducing the amount of this greenhouse gas in the atmosphere. Additionally, there are emerging technologies such as direct air capture, which aims to extract carbon dioxide directly from the air.

 

Ocean - based geoengineering is also being explored. For example, fertilizing the ocean with iron to stimulate the growth of phytoplankton, which can absorb carbon dioxide. But this may also have unforeseen consequences on marine ecosystems. Geoengineering is a complex and controversial field. While it offers possible ways to combat climate change, careful consideration of its potential impacts on the global environment is crucial.

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...
