climate change

Climate change has become a major challenge of our time. In 2013, the United Nations Intergovernmental Panel on Climate Change (IPCC) clearly indicated in its Fifth Assessment Report that the increase in the atmospheric greenhouse gas concentration due to human activities are extremely likely responsible for the observed global warming since the middle of the 20th century.

The Hong Kong Observatory (HKO), as the government department responsible for studying the scientific basis of climate change, has over the years been actively carrying out research on climate change in Hong Kong and sparing no effort in its public education activities.

This webpage serves to provide the public with a convenient means to access various information related to global and local climate change, including background on global climate change, observed climate change in Hong Kong, future climate projections, educational resources, climate change outreaching activities in Hong Kong, and publication and references, etc.
