Climate Change

Warming of the climate system is unequivocal
Almost every corner of the globe has experienced a warming trend during 1901-2012. Global warming has led to widespread melting of snow and ice, rise in mean sea level and changes in frequency of extreme weather events.
Hong Kong is not immune to climate change
Against the backdrop of global warming, the warming trend in Hong Kong has been exacerbated by local urbanization. Over the last hundred years, extremely hot days and extreme precipitation have become more frequent, while extremely cold days have become rarer.
Human activity is the culprit
Burning of fossil fuels and deforestation have led to significant increase in the atmospheric concentration of greenhouse gases which trap extra heat on Earth. The present-day concentration of carbon dioxide is unprecedented in at least the last 800,000 years.
What if greenhouse gas emissions continue to increase?
Globally, there will be more hot extremes as global mean temperature continues to increase. Dry regions will get drier, wet regions will get wetter. Meanwhile, global mean sea level will continue to rise, increasing the threat of storm surge and the risk of coastal inundation.
