An
estimated 14,500 deaths across China in 2020 could be attributed to
heatwaves, almost doubling a historical average from 1986 to 2005, while
an estimated 1.4 per cent was knocked off China’s gross domestic
product in 2020 alone as soaring temperatures cut working hours.
Exposure
to wildfires in recent years has increased, as compared with two
decades ago, and extreme precipitation – like the rains that caused
deadly floods in Henan province earlier this year – has the potential to
reverse China’s gains in flood emergency response capacity.

Those
are among the findings of a stark report from dozens of experts across
25 institutions in China and around the world. The report, published on
Sunday in The Lancet Public Health journal, is part of a global
initiative known as the Lancet Countdown, which looks at the
relationship between health and climate change.
“The health
impacts of climate change continue to worsen in every province in China
and there is mixed progress in the adaptation and mitigation responses,”
wrote the authors, who were led by Tsinghua University’s department of
Earth system science.
“After the painful lessons
from Covid-19, this important opportunity to protect the health of
people in China, both now and in the future, cannot be missed.”
The
findings of the China report were released on the heels of a Lancet
Countdown global report published late last month, which found “a world
overwhelmed by an ongoing global health crisis, which has made little
progress to protect its population from the simultaneously aggravated
health impacts of climate change”.
That report, and related projects
from regional partners including China, come as world leaders have
turned their attention to the climate crisis, meeting in Glasgow for two
weeks for the UN Climate Change Conference of the Parties (COP26),
which seeks to bolster coordination in slowing rising temperatures and
combating climate change.
A spotlight falls on China’s role in
those next steps, as the world’s largest greenhouse gas emitter and most
populous country. In recent weeks, China’s government has released a
road map for how it plans to reach previously stated goals of peak
emissions by 2030 and carbon neutrality by 2060.
But
as Beijing makes these pledges, crafts a domestic plan for climate
change adaptation and looks to shore up its health emergency capacities
following the outbreak of Covid-19 last year, it must make sure it
thinks holistically about the health impacts of environmental change,
according to report’s authors.
“The risk of
decisions made in isolation is that China might not fully realise the
health and economic benefits of addressing the pandemic alongside
tackling climate change, which is likely to be a larger global public
health threat than Covid-19 in the long run,” they wrote.

While
each region in China faces unique health and climate threats, the most
worrying trends were a rise in heat-related deaths, labour loss, and
risk of dengue fever in Guangdong; risk of flood and drought in Sichuan
province, and wildfire exposures in Liaoning and Jilin provinces, said
the authors, who examined available national and provincial data in
recent years and decades, focusing largely on tracking trends over the
past 20 years.
“We need to control the burden of
disease in China, we need to pay attention to climate change and its
impact on public health,” Tsinghua economic professor and The Lancet
Countdown Regional Centre for Asia director Cai Wenjia said at the
report launch on Monday in Beijing.
Cai also pointed to the need for global efforts to control rising temperatures.
“If
we do not make interventions, the extreme weather conditions … will
increase, [also] resulting in increasing economic loss,” she said.
Six
provinces of the 30 that responded to the group’s questionnaire
reported that they had devised health and climate change adaptation
plans, and another six were developing such plans, according to Cai.
Only four reported that they had completed an assessment of the health impacts of climate change.
There
were bright spots on China’s record, according to the report. When it
came to air pollution, premature deaths due to exposure to ambient
particulate matter of 2.5 microns or less (PM2.5) had continued to
decline.
However, 98 per cent of China’s cities still had annual
average PM2.5 concentrations that are more than the World Health
Organization guidelines.
Urban green space had also increased in
18 of 31 provinces in the past decades, according to the authors, who
described it as an important measure for coping with rising global
temperatures.
But overall, more could be done when it came to
encouraging green investments and reducing fossil fuel use, as well as
preparing health systems, according to the report.
“Even
with a Paris Agreement compliant pathway, additional, and more
ambitious, health-focused climate action plans in China could prevent
millions of deaths from reducing air pollution, improving diet and
increasing physical activity,” the authors said.
