Paleoclimate data indicate there was less Arctic sea ice during the pre-industrial period than in modern times, or when CO2 concentrations were 100 ppm lower than today (280 vs. 380 ppm).
Scientists (Diamond et al., 2021) assert that during the 18th and 19th centuries Arctic sea ice extent minimum (September) values averaged 5.54 million km². Though modern sea ice losses are often characterized as dangerously low, satellite data indicate the 2002-’06 five-year average minimum sea ice extent was 5.92 million km², which is 0.38 km² above the 1700s and 1800s or pre-industrial (PI) levels. ...
Several other studies also affirm the sea ice losses observed via satellite in recent decades are not unusual or unprecedented when compared to past centuries.
The COVID-19 pandemic wasn’t all bad, a new Biden admin plan to fight climate change argues: It at least “highlighted major opportunities” to reduce travel demand and lower carbon emissions through “remote work and virtual interactions.” The plan—which President Joe Biden’s Environmental Protection Agency and Energy, Transportation, and Housing departments released in January—aims to “eliminate nearly all greenhouse gas emissions” from the transportation sector by 2050, mostly through a transition to electric vehicles. Also included in the plan, however, is a controversial call to reduce “commuting miles” through “an increase in remote work and virtual engagements,” including in education. ...
Jazz Shaw of Hot Air has a prediction: "I can’t shake the feeling that this brings us one step closer to a declared “climate emergency.” You people can all stay locked down in your homes voluntarily to save the polar bears or we can declare an emergency and lock you down like we did during COVID."
NY Post: Experts are now recommending that doctors reduce their use of certain kinds of anesthesia in order to combat the effects of climate change. Dr. Mohamed Fayed, a senior anesthetist at Detroit’s Henry Ford Health, made the suggestion during the American Society of Anesthesiologists’ annual conference last Friday in Orlando, Florida. “Global warming is affecting our daily life more and more, and the reduction of greenhouse gas emissions has become crucial,” he said. Dr. Fayed added, “No matter how small each effect is, it will add up. As anesthesiologists, we can contribute significantly to this cause by making little changes in our daily practice — such as lowering the flow of anesthetic gas — without affecting patient care.”
Research notes that inhaled anesthesia accounts for up to 0.1% of the world’s carbon emissions, which are regarded as the primary driver of global climate change. An hour of surgery using an inhaled anesthetic is equivalent to driving as many as 470 miles, according to a 2010 study.
Flashback 2020 Study in American Cancer Society Journal in 2020 Fretted over ‘carbon footprint of cancer care’ - ACS Journal: "Climate change and cancer" - Excerpt: "To date, no studies have estimated the carbon footprint of cancer care...The energy expenditure associated with operating cancer treatment facilities and medical devices, as well as the manufacturing, packaging, and shipment of devices and pharmaceuticals, contributes significantly to greenhouse gas emissions in cancer care...Some cancer treatment facilities have begun to consider their own carbon footprint and started a process to achieve carbon neutrality."
Climate Depot's Morano: "Here is a question for the American Cancer Society: If you need cancer treatment, would you go to a cancer treatment center that was worried about its carbon footprint? Or one that was worried about delivering the best possible modern care possible?"
Researchers predict that by 2100, US case numbers will increase by 50 percent - Spread is due to global warming, meaning more hot areas for the fungus to grow. ... The fungus is endemic to the desert-like parts of the Southwest, and 97 percent of all American cases are found in Arizona and California. But a study in the journal GeoHealth predicted that, due to climate change, the endemic region of the fungus will spread north to include dry western states such as Idaho, Wyoming, Montana, Nebraska, South Dakota, and North Dakota. In a high-warming scenario, this would mean that by 2100 the number of affected states could rise from 12 to 17, while the number of cases could increase by 50 percent.
