It would be a negative feedback.
Increased CO2 emissions -> Decreased population (increased deaths)

Global Warming Would Cut Deaths

The risk of a fatal heatwave in the UK within ten years is high, but
overall global warming may mean fewer deaths due to temperature, a
report says.
A seriously hot summer between now and 2017 could claim more than 6,000
lives, the Department of Health report warns.
But it also stresses that milder winters mean deaths during this time of
year - which far outstrip heat-related mortality - will continue to
decline.
The report is to help health services prepare for climate change
effects.
A panel of scientific experts commissioned by the Department of Health
and Health Protection Agency (HPA) has looked at the way the UK has
responded to rising temperatures since the 1970s, and how the risks are
likely to change.
While summers in the UK became warmer in the period 1971 - 2003, there
was no change in heat-related deaths, but annual cold-related mortality
fell by 3% as winters became milder - so overall fewer people died as a
result of extreme temperatures.
Rather than physiological changes explaining our ability to adapt to
rising temperatures, the report puts this down primarily to lifestyle
alterations - our readiness to wear more informal clothes, for instance,
and the shift away from manual labour.
Breathing in
Nevertheless, there is at present a 25% chance that by 2017 south-east
England will see a severe heatwave which could cause 3,000 immediate
deaths and the same number of heat-related deaths throughout the summer.
Why more die in winter
While the authors acknowledge that predicting heatwaves and their
effects is difficult, the risk was nonetheless "high".
However, even 6,000 deaths pales in comparison with the number of
cold-related deaths, which in the UK currently average about 20,000 per
year.
It is also a mixed picture when it comes to the health impact of air
pollution.
As a result of regulations, levels of several key pollutants are likely
to decline over the next 50 years, but the concentration of ozone may
well increase.
Climate change poses great challenges and it is important to plan
ahead for the health consequences
Dawn Primarolo
Public Health Minister
This is associated with breathing difficulties, particularly for
asthmatics and those with existing lung problems, and could lead to
1,500 extra hospital admissions and deaths every year.
Skin cancer meanwhile is also likely to increase, although there are
studies which suggest greater exposure to sunlight may prevent other
forms of cancer.
Other areas which had caused concern may transpire not to be as worrying
as initially thought.
A reappraisal of the evidence suggests malaria outbreaks are likely to
remain rare, although health authorities need to be alert to outbreaks
in continental Europe which could affect travellers, the report says.
However, while vector-borne diseases may not be the problem once
thought, food-borne ones remain an issue: improved food hygiene will be
necessary to prevent a 14.5% increase in food poisoning by bacteria such
as Salmonella, which is affected by rising temperature.
More work ahead
Sudden periods of heavy rain may well increase the risk of flooding in
some places although certain types of flooding - notably those linked to
melting snow - may become less common.
While flooding is traumatic for those affected, it causes few direct
deaths. Relatively little is known about the total health effects of a
flood, and more work is needed, the report adds.
However heavy rain over a short period can certainly increase the amount
of bacteria in surface drinking water, while increasing temperatures may
stop current disinfection methods from working properly - a challenge
which needs to be addressed.
"Climate change poses great challenges and it is important to plan ahead
for the health consequences," said Public Health Minister Dawn
Primarolo.
"Let's not forget we also have a societal role to play in the mitigation
of climate change by supporting sustainable development programmes -
through consumer choice, reducing our carbon footprints and recycling
waste."
Gill Morgan, head of the NHS Federation, said the country's health
service "has a major role to play in tackling climate change".
"As the report highlights, rising temperatures will put significant
pressure on the NHS, and may increase the amount of heat-related deaths
and skins cancers, as well as respiratory and insect-borne diseases."
