Global warming is the current long-term rise in the average temperature of the Earth’s climate.
Climate change is shown by temperature measurements and by multiple effects of the warming.
Climate change exacerbates adverse effects of air pollution on health with: higher temperatures enhancing ground level ozone information, increased risk of wildfires and dust storms.
PM 25 from wildfire smoke and the storms increase the risk of cardiovascular disease.
Higher temperatures increase the demand for electricity, which increases fossil fuel combustion and pollution.
It is projected that with high greenhouse gases emissions, the frequency of wildfires will substantially increase over 74% of the global landmass by the end of this century.
Presently, the term global warming refers to the mainly human-caused observed increase in global surface temperatures.
There have been much earlier periods of global warming.
The terms global warming and climate change are commonly used interchangeably.
Climate change, however, includes both global warming and its effects, such as changes to precipitation and impacts that differ by region.
Climate change amplifies storm hazards by ocean warming, air temperature rise, rising ocean heat content, and increasing atmospheric moisture capacity, compounded by a rise in sea levels.
Atlantic hurricanes have become stronger, weather, and slower moving over the past few decades.
Many changes since mid 20th century have been unprecedented compared to records over decades to thousands of years.
In 2013, the Intergovernmental Panel on Climate Change (IPCC) concluded, that is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century.
The emission of greenhouse gases of significance include carbon dioxide, methane, and nitrous oxide.
Mean greenhouse gas emissions for different food types:
g CO2-Ceq per G protein
Ruminant meat 62
Recirculating Aquaculture 30
Trawling Fishery 26
Non-recirculating Aquaculture 12
Non-trawling Fishery 8.6
Starchy Roots 1.7
The US healthcare emissions is about 655 million metric tons of carbon dioxide with an annual loss of 470 disability adjusted life years, and is associated with an annual loss of life in the United States equal to leukemia or prostate cancer.
Greenhouse Gas Emissions From U.S. Healthcare On the Rise
The U.S. healthcare sector pollutes more than any other industrialized health system in the world
The U.S. healthcare system has increased its greenhouse gas emissions across the last decade, and is the greatest polluter of any industrialized healthcare system in the world.
Greenhouse gas emissions from the U.S. healthcare system rose by 6% across the last decade.
In 2018, greenhouse gas emissions and toxic air pollutants resulted in the loss of 388,000 disability-adjusted life-years.
Money spent on drugs, medical devices, hospital supplies, and other resources result in emissions from the production of those goods.
The U.S. healthcare system is responsible for around a quarter of worldwide greenhouse gas emissions, and the damage stemming from this pollution is equivalent to that of deaths from preventable medical errors.
Emissions classified into three groups: direct from hospitals and other healthcare sectors: energy use and anesthetic gases, indirect from expenditures on electricity, and indirect from the production of healthcare goods and services.
Emissions from the healthcare system make up around 8.5% of total greenhouse gas emissions in the U.S.
More than 80% of national healthcare sector emissions were contributed by the supply chain, with pharmaceuticals and chemicals having the most impact on pollution.
Expenditures on electricity contributed to about 11% of overall healthcare emissions, and direct emissions from hospitals and other facilities contributed about 7%.
Do you effects of climate change on oncology patients is particularly significant due to the increases in temperature, infectious disease, pollution, and malnourishment may have a greater effect on those with compromised immunity and comorbid illnesses.
Methane has a heat-trapping potential nearly 100 times larger than carbon dioxide.
Nitrous oxide has a global warming potential almost 300 times greater than carbon dioxide.
Cows produce between 250 and 500 liters of methane a day.
