8. 17 Sustainable
Development Goals
Set in 2015 by
the United Nations
169 specific
targets
To be achieved
by 2030
THE GLOBAL GOALS
For Sustainable Development
UNIVERSAL TRANSFORMATIVE INTEGRATED

10. SDG 13 Climate Action

11. CAN YOU
GO FAR FOR
CLIMATE?
Future generations will
most likely look back at
this moment as the single
most significant turning
point for action.
So take a deep breath
and decide that
collectively, we can do
this. And you will play
your part.
Christiana Figueres
Former UN Climate Chief who oversaw the historic Paris
Climate Agreement and now is co-founder of Global
Optimism.

12. What is
climate?
• Weather = short time
• Climate = average
weather over long time
• Highly complex system

13. What cause climate to change?
§ NOT only human activities à Greenhouse gas
§ Changes in atmosphere
§ Natural processes: Volcanoes, tectonic plate movement,
changes in the sun

14. Climate Change = Global warming?
Climate Change Global Warming
A broader term refers to long-term
changes in climate, including average
temperature and precipitation and wind
patterns
The increase of the Earth’s average
surface temperature due to a build-up of
greenhouse gas in the atmosphere
Includes the “side effects’ of warming –
melting glaciers, heavier rainstorms, more
frequent drought
Refer to rising surface temperature only

16. Climate Change = Global warming?

17. Climate Change = Global warming?
Human impacts on Carbon Cycle

18. 99% nitrogen and oxygen, with important trace greenhouse gases:
• Water vapor (10- 50,000ppm)
• Carbon dioxide (400 ppm)
• Methane (1.8 ppm)
• Nitrous oxide (330ppb)
The Science behind Climate Change :
Atmospheric Gases
Without the greenhouse effect, Earth’s
surface temperature would be below
freezing (-17oC).

19. Greenhouse effect
The greenhouse effect is a process that occurs when gases in Earth's
atmosphere trap the Sun's heat.

20. Climate Change = Global warming?
Global warming is affecting extreme events

21. Climate Change = Global warming?

23. Climate Change = Global warming?
A crucial role played by the
oceans involves the mixing
of surface heat into the
deep layers
à redistribution of heat
around the globe.
Oceans are Warming
The vast majority of Earth’s heat
is stored in the oceans.
The heat in the world’s
oceans reached a new
record level in 2019 L

24. Climate Change = Global warming?
Sea Levels Are Rising
Caused by
- Warm, melting waters
- Melting ice sheets
(Antarctica, Greenland)
- Melting glaciers

A study by Climate Central estimates that 1.3 million Hongkongers could be hit by flooding
every year in areas such as Tai Po, Sha Tin, and at the Hong Kong International Airport.

34. Survey on HK People’s Attitudes towards Climate Change
Source: Hong Kong Public Opinion Research Institute (January 2020)
§ 84% think the impact of climate change on future generations is going to be
significant.
§ 84% claimed they had very often practised energy saving to reduce carbon
emission in the past year, usually by using more public transport.
§ Most people think the government has the main responsibility for tackling
climate change. And over half did not think it was doing enough to reduce
carbon emissions.
§ Most people think climate change mitigation and adaptation measures should
be funded by government reserves and “polluter pays” tax income. More than
70 % are willing to pay more for electricity to fund an increase in renewable
energy use. On average, they are willing to pay about 20% more.
