Those of us who live in the United
States or a European country, and who fret about the future of the global
climate, have an understandable tendency to focus on what’s going on in the so
called western region of the world. We
might be upset with the Trump administration’s policies regarding the uses made
of federal lands, or with rollbacks of legislation having to do with emissions
from coal fired power plants. We of
course should be concerned—dismayed at the undoing of laws and regulations that
affect our well-being in the here and now, or failures to join with other
nations of the world in setting goals for drawdowns of CO2 emissions
in the years ahead. But if we are to be effective advocates for policies and
practices of global significance we need to
keep in mind our place in the global picture. There’s no better way to put this into
perspective than to think about China. I
recently ran across a paper published in the Proceedings of the National Academy of Science, entitled Climate Change, human impacts and carbon sequestration in China. China
is now the world’s second largest economic entity, next to the United
States. That’s impressive, but even more
important is the fact that China is changing more rapidly than any other major
national socioeconomic system except possibly India. These changes are
inexorable, and the implications for the planetary climate are profound. China
is a large and powerful entity in its own right, and it exerts immense
influence on a surrounding region that embraces a substantial fraction of the
world’s population. As China goes, so
also will a good bit of the rest of the world.
Let’s
look at this graph, lifted from the PNAS research paper I alluded to above. It reveals some important facts and
projections:
The
upper part of the figure is easy to follow. The
blue line shows the growth of China’s Gross Domestic Product (GDP). You can see that it’s shot up like mad in the
past decade, and it continues to climb at a furious rate. Then look at the green line, which shows
population over time. Two important things:
China’s population is not increasing, and in all likelihood it will not
do so in the future. But it’s already huge.
At 1.37 billion people, its population is about 4.3 and 2.7 times greater than
that of the United States and the European Union, respectively. The third line on the graph shows the rate
of CO2 emissions. These have
been increasing rapidly as China looks for the energy to propel its social and
economic development. The major fuel for
this is coal. In 2013 China accounted
for about 27% of global CO2 emissions.
The timeline below
the graph tells a powerful story. Mao
Zedong, the founder of the People's Republic of China was responsible for the
disastrous policies of the 'Great Leap Forward'. Between 1958 and 1962, a third of all homes
in China were destroyed to produce fertilizer and the nation descended into
famine and starvation. In his misplaced
monomania about producing an agricultural revolution, Mao mandated vast
deforestation and conversion of natural ecosystems to cropland. By the time
reforms were enacted, huge damage had been done to China’s ecosystems. Then the economic growth that came with
reform drove massive increases in coal burning, with accompanying pollution. To quote from the PNAS paper:
“Fast
economic development can be detrimental to the environment through land-use
change, consumption of resources, and pollution. For example, land conversion
to agriculture in northern China resulted in a drastic decline of the
groundwater table and associated water shortage. China’s application of
chemical fertilizers and pesticides accounted for about 36% and 25%, respectively,
of the global usage. Fast economic development, along with the lack of strong
environmental regulation, has resulted in severe and widespread air, water, and
soil pollution in China: a quarter of the nation’s cities are affected by acid
rain; soil erosion affects 19% of its land area; about 75% of lakes are
polluted; and 15–20% of the country’s species are endangered. CO2 emission
reduction in China is thus not only essential for achieving the global
emission-reduction target but also critical for its own environmental
protection and sustainable development.”
China
is making strong efforts to reverse the policies of the past and to restore
ecosystems, even in the face of enormous pressures to maintain its economic
gains. C emissions per unit of GDP will be reduced by 60–65% from the 2005 level;
the share of nonfossil fuels in the energy mix will be increased to 20%; forest
volume will increase by 31.6%
relative to the 2005 level.
Consider
the percentages of energy production that are renewable, as of 2015: China 25%; Germany 32%; United Kingdom, 27 %;
United States, 14%. Just to keep us a
bit more humble humble about all this, Denmark comes in at 69%. We in the US have a long
way to go, and every reason to try to do better.
Bottom
line for me is that Drawdown must be a global movement if it is to
succeed. We have a lot to do at home, but we should be active in responding to actions
our government and large corporations take all over the globe.
