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
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.
