If you\u2019ve been following recent debates about health, you\u2019ve been hearing a lot about vaccines<\/a>, diet, measles, Medicaid cuts and health insurance costs<\/a> \u2013 but much less about one of the greatest threats to global public health<\/a>: climate change.<\/p>\n

Anybody who\u2019s fallen ill during a heat wave, struggled while breathing wildfire smoke<\/a> or been injured cleaning up from a hurricane<\/a> knows that climate change can threaten human health. Studies show that heat, air pollution, disease spread and food insecurity linked to climate change are worsening and costing millions of lives around the world each year<\/a>.<\/p>\n

The U.S. government formally recognized these risks in 2009 when it determined that climate change endangers public health and welfare<\/a>.<\/p>\n

However, the Trump administration is now moving to rescind that 2009 endangerment finding<\/a> so it can reverse U.S. climate progress and help boost fossil fuel industries, including lifting limits on greenhouse gas emissions from vehicles and power plants. The administration\u2019s arguments for doing so are not only factually wrong<\/a>, they\u2019re deeply dangerous to Americans\u2019 health and safety.<\/p>\n

\"Health<\/a><\/p>\n

Health risks and outcomes related to climate change.
\n World Health Organization<\/a><\/p>\n

As physicians<\/a>, epidemiologists<\/a> and environmental health<\/a> scientists<\/a> who study these effects, we\u2019ve seen growing evidence of the connections between climate change and harm to people\u2019s health. More importantly, we see ways humanity can improve health by tackling climate change. <\/p>\n

Here\u2019s a look at the risks and some of the steps individuals and governments can take to reduce them.<\/p>\n

Extreme heat<\/p>\n

Greenhouse gases from vehicles, power plants and other sources accumulate in the atmosphere, trapping heat<\/a> and holding it close to Earth\u2019s surface like a blanket. Too much of it causes global temperatures to rise, leaving more people exposed to dangerous heat more often.<\/p>\n

Most people who get minor heat illnesses will recover, but more extreme exposure, especially without enough hydration and a way to cool off, can be fatal. People who work outside, are elderly or have underlying illnesses such as heart, lung or kidney diseases are often at the greatest risk.<\/p>\n

Heat deaths have been rising globally, up 23%<\/a> from the 1990s to the 2010s, when the average year saw more than half a million heat-related deaths. Even in the U.S., the Pacific Northwest heat dome in 2021 killed hundreds of people<\/a>. <\/p>\n<\/p>\n

Climate scientists predict<\/a> that with advancing climate change, many areas of the world, including U.S. cities such as Miami<\/a>, Houston<\/a>, Phoenix<\/a> and Las Vegas<\/a>, will confront many more days each year hot enough to threaten human survival.<\/p>\n

Extreme weather<\/p>\n

Warmer air holds more moisture, so climate change brings increasing rainfall and storm intensity, worsening flooding, as many U.S. communities have experienced<\/a> in recent years. Warm ocean water also fuels more powerful hurricanes<\/a>.<\/p>\n

Increased flooding carries health risks, including drownings, electrocution<\/a> and water contamination from human pathogens and toxic chemicals. People cleaning out flooded homes also face risks from mold exposure, injuries and mental distress.<\/p>\n

Climate change also worsens droughts<\/a>, disrupting food supplies and causing respiratory illness from dust and dry conditions as well as wildfires. And rising temperatures and aridity dry out forest and grasslands, making them more vulnerable to catching fire<\/a>, which creates other health risks.<\/p>\n

Air pollution<\/p>\n

Wildfires, along with other climate effects, are also worsening air quality<\/a> around the country.<\/p>\n

Wildfire smoke is a toxic soup of microscopic particles<\/a> (known as fine particulate matter, or PM2.5) that can penetrate deep in the lungs and hazardous compounds<\/a> such as lead, formaldehyde and dioxins generated when homes, cars and other materials burn at high temperatures. Smoke plumes can travel thousands of miles downwind<\/a> and trigger heart attacks<\/a> and elevate lung cancer risks<\/a>, among other harms<\/a>.<\/p>\n<\/p>\n

Meanwhile, warmer conditions favor the formation of ground-level ozone<\/a>, a heart and lung irritant<\/a>. Burning of fossil fuels also generates dangerous air pollutants that cause a host of health problems, including heart attacks, strokes<\/a>, asthma flare-ups<\/a> and lung cancer<\/a>.<\/p>\n

Infectious diseases<\/p>\n

Because they are cold-blooded organisms, insects are directly influenced by temperature. So as temperatures have risen, mosquito biting rates have risen as well. Warming also shortens the development time of disease agents that mosquitoes transmit. <\/p>\n

Mosquito-borne dengue fever has turned up<\/a> in Florida, Texas, Hawaii, Arizona and California. New York state just saw its first locally acquired case of chikungunya virus<\/a>, also transmitted by mosquitoes.<\/p>\n

As global temperatures rise, regions are becoming more suitable for mosquitoes to transmit dengue virus. The map shows a suitability scale, with red areas already suitable for dengue transmissions and yellow areas becoming more suitable.

And it\u2019s not just insect-borne infections. Warmer temperatures increase diarrhea and foodborne illness from Vibrio cholerae and other bacteria<\/a> and heavy rainfall increases sewage-contaminated stormwater overflows<\/a> into lakes and streams. At the other water extreme, drought in the desert Southwest increases the risk of coccidioidomycosis<\/a>, a fungal infection known as valley fever.<\/p>\n

Other impacts<\/p>\n

Climate change can threaten health in numerous other ways. Longer pollen seasons<\/a> can increase allergen exposures<\/a>. Lower crop yields can reduce access to nutritious foods<\/a>. <\/p>\n

Mental health can also suffer, with anxiety, depression<\/a> and post-traumatic stress<\/a> following disasters<\/a>, and increased rates of violent crime and suicide<\/a> tied to high-temperature days.<\/p>\n

Young children<\/a>, older adults<\/a>, pregnant women<\/a> and people with preexisting medical conditions are among the highest-risk groups. Often, lower-income people are also at greater risk because of higher rates of chronic disease, higher exposures to climate hazards and fewer resources for protection, medical care<\/a> and recovery from disasters.<\/p>\n

What can people and governments do?<\/p>\n

As an individual, you can reduce your risk by following public health advice during heat waves, storms and wildfires; protecting yourself against tick and mosquito bites; and spending time in green space that improves your mental health<\/a>.<\/p>\n

You can also make healthy choices that reduce your carbon footprint, such as:<\/p>\n

However, there are limits to what individuals can do alone. <\/p>\n

Actions by governments and companies are also necessary to protect people from a warmer climate and stop the underlying causes of climate change. <\/p>\n

Workplace safety can be addressed through rules to reduce heat exposure for people who work outdoors in industries such as agriculture and construction<\/a>. Communities can open cooling centers<\/a> during heat waves, provide early warning systems<\/a> and design drinking water systems<\/a> that can handle more intense rainfall and runoff, reducing contamination risks.<\/p>\n

Governments can ensure that public transit is available and not overly expensive to reduce the number of vehicles on the road. They can promote clean energy rather than fossil fuels to cut emissions, which can also save money since the cost of solar energy has dropped spectacularly<\/a>. In fact, both solar<\/a> and wind energy are less expensive than fossil fuel energy<\/a>. <\/p>\n

Yet the U.S. government is currently going in the opposite direction, cutting support for renewable energy while subsidizing the fossil fuel industries that endanger public health<\/a>. <\/p>\n

To really make America healthy, in our view, the country can\u2019t ignore climate change.<\/p>\n","protected":false},"excerpt":{"rendered":"If you\u2019ve been following recent debates about health, you\u2019ve been hearing a lot about vaccines, diet, measles, Medicaid…\n","protected":false},"author":2,"featured_media":287383,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[47],"tags":[192,79],"class_list":{"0":"post-287382","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-environment","8":"tag-environment","9":"tag-science"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/287382","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=287382"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/287382\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/287383"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=287382"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=287382"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=287382"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
