Global Climate Change and China
Alex Huang, Atmospheric Sciences
Students will learn the science of global
climate change and its impacts to China. The
subjects include geography, climate zones,
and historical climate of China. The

Temperature Changes of the Past 50 Years in China
Tendency of mean annual temperature in China from
1951 to 2001. (Ren Guoyu 2004).
Why should China be concerned about
climate change?
• China is under international pressure for actions
• Climate change interrupts agriculture production
• Climate change affects people’s lives and properties
• Climate change hinders economic growth and
political stability

Why should China do about climate change?
• China has to continue its rapid economic development
• China has to maintain political stability
• China has to mitigate the impacts of climate change
• China has to reduce the dependency of coal
• China has to upgrade its infrastructure of industry
• China has to defend its international reputation
The Bottom Line is
Controlling carbon dioxide emissions without
hindering economic development is a major
challenge for China and the world
(Zeng et al 2008).
China’s Policies and Actions for Addressing Climate
Chang by the National development and Reform
Commission, PRC (2012)
Goals:
• To reduce energy consumption per unit of GDP by
16 percent by 2015 from the level in 2011 (2%
reduction in 2011).
• Cut CO2 emissions per unit of GDP by 17 percent
by 2015 (40% by 2020) compared to 2005 levels.
• Raise the proportion of non-fossil fuels in the
overall primary energy mix to 11.4% by 2015
( 8.6% in 2011).

6. Proactive Participation in International Negotiations
(III) China’s Basic Positions and Stand on Participation in the
Doha 2012 UN Climate Change Conference
•
Addressing climate change is based on the principles
of fairness and the principle of “common but
differentiated responsibilities and own capacities.”
•
Developed countries should fulfill their promises to
reduce emissions and provide support in terms of
funding, technology transfer and capacity building,
and ensure that the already-established mechanisms
and institutions start substantive work, and play a
substantial role in offering support to developing
countries in coping with climate change.
The Bottom Line is
China recognizes the urgency and importance of the
climate change issue and attempts to mitigate the
impacts of climate change; however,
China is vast and the overhaul of infrastructure is a
demanding challenge.
