Climate Change Is The Greatest Threat To Human Health In History
In early October the United Nation’s Intergovernmental Panel on Climate Change (IPCC), the entire world’s definitive scientific body on the topic, published, ‘Global Warming of 1.5C.’ Over 90 scientists from 40 countries reviewing 6,000 studies prepared the IPCC report in response to a 2015 Paris climate accord request. Its purpose was to discriminate involving the effects of global warming at 1.5°C (2.7°F) versus 2.0°C (3.6°F). The Paris accord called for holding warming below 2.0°C while pursuing efforts to limit it to 1.5°C. For example, should temperatures increase to 1.5°C, the report found of 105,000 species studied, four percent of vertebrates, six percent of insects and eight percent of plants would lose half of their climatically-determined geographic range. At 2°C the percents double to triple. At 1.5°C we will lose 70 to 90 percent of coral reefs, at 2°C there is going to be a 99 percent loss.
The IPCC report is just one of many latest in an ever-increasing quantity of publications by leading national and international science bodies that conclude all life on this planet is under existential threat. What does the IPCC report additionally the subsequently published 4th National Climate Assessment and Lancet’s ‘Countdown on Health and Climate Change,’ the 2017 ‘Climate Science Special Report’ (CCSR), additionally the 2016 Obama Administration report titled ‘The Impacts of Climate Change on Human Health in america; A Scientific Assessment,’ conclude relative to the effects of global warming on human health?
Per all of these reports, the earth has warmed by 1°C since the pre-industrial era and two-thirds with this rise has occurred since 1986. The twenty warmest years on record have occurred over the past 22 years. Because air temperatures are significantly determined by ocean temperatures, they have warmed considerably over the past few years. In 2017 these people were shockingly warm. They exceeded 2015, the second warmest ocean temperature year, by 1.51 x 10^22 Joules, or the number of electrical energy China produces annually. Among other calamitous results of ocean warming is acidification – particularly problematic for phytoplankton that produces half the oxygen we breath.
As for global warming’s cause, or the nearly linear relationship between greenhouse gas emissions ad atmospheric warming, over 42 billion tons of greenhouse pollution are dumped worldwide into the atmosphere every year additionally the amount is again increasing. Per the Global Carbon Project carbon emissions are expected to increase by 2.7 percent for 2018 due in part to five consecutive years of rising oil consumption. The US is historically the largest emitter of greenhouse gas pollution and currently ranks second behind China in annual emissions. Carbon dioxide, now measured at over 400 parts per million (ppm), a 65 percent increase over pre-industrial levels, last occurred three million years ago. Concerning how will climate change affect you and your community essay the discharge rate, last year’s CCSR report concluded, ‘there is no climate analog for this century any time in at least the final 50 million years.’
Absent significant changes in political will worldwide, the EPA admitted in a recent environmental impact statement that atmospheric carbon concentrations will rise to nearly 800 ppm by the end with this century. This would be due in part to President Trump’s decision to withdraw from the Paris accord and decisions by the administration to relax restrictions on auto tailpipe emissions that account for approximately 20 percent of US greenhouse pollution, rules limiting coal fired power plants CO2 emissions that account for nearly 30 percent, and regulations requiring drilling companies to restrict venting or flaring methane, a far more potent greenhouse gas than CO2, and monitoring and repairing methane leaks. Atmospheric concentrations of methane are currently the highest on record.
While health has been effected by climate and weather, it will be the change in climate and climate variability, particularly changes in weather extremes, that is a significant threat to human health. Again, absent dramatic and near term changes in political will, temperatures are expected to increase by 4°C by the end with this century. What do increasing temperatures mean for human health? (Readers should remember that unless otherwise indicated statistics cited below come from the Obama Administration’s 2016 report.)
Warmer air holds more water and greater or rising temperatures cause higher surface evaporation that in turn advances the number and severity of rain events, now termed rain bombs, resulting storm surge additionally the intensity, frequency and duration of hurricanes. For example, the devastation caused by last year’s Hurricane Harvey was in part the result of Gulf surface temperatures for the first time on record never falling below 23°C. Hurricane Maria, the deadliest storm of the hyperactive 2017 Atlantic hurricane season, accounted for nearly 3,000 deaths across decimated Puerto Rico. Harvey, Irma and Maria combined caused over $300 billion in damages. This year’s Hurricane Michael, with sustained 155 mph winds, was one of many four most intense hurricanes to hit the mainland since records began in 1851. Michael made landfall along the Florida panhandle, where it reached nearly 20 feet in storm surge and remarkably remained a category three storm as far inland as Macon, Georgia. Recent research published into the journal Nature concluded global warming will cause hurricanes to become even more deadly by intensifying rainfall by as much as 10 percent and wind speeds by 25 mph.
Beyond the increasing severity of hurricane events, global warming means the current rate of rise in Global Mean Sea Level is greater than any time in at least 2,800 years. As for rising sea levels from ice melt, should Greenland ice sheets thaw in their entirety they would add 20 feet towards the height of global seas. The thaw of the West Antarctic Ice Sheet, that is presently vanishing faster than any previously recorded time, would add another 10 feet. At 20 feet, nearly all of Florida and a third of New York City would be under water. Keep in mind 145 million people worldwide live three feet or less above sea level and 10 percent of the world’s population or nearly 800 million live not as much as 30 feet from present sea levels. Eleven of the 16 megacities, those with more than 15 million people, are built on coasts, for example, Jakarta, Los Angeles, Manila, Mumbai, Osaka, Shanghai and Tokyo.
Rising seas or flooding compromises drinking water, human waste water treatment and storm water disposal that, in turn, results in increased risk of waterborne diseases caused by pathogens such as bacteria, viruses and protozoa. Between 1948 and 1994, 68 percent of waterborne disease outbreaks in the US were preceded by extreme precipitation events. Waterborne diseases may actually be underestimated by as much as 43-fold and by up to 143 times for Vibrio species, for example, Vibrio cholerae Severe storm events also means increased food contamination via increases into the transport of pathoge such as salmonella and noroviruses. Global warming is therefore influencing the fate, transport, transmission, viability and multiplication rate of pathogens into the food chain. Cases of Legionnaires’ disease, spread by contaminated aerosolized water have not surprisingly increased by nearly 200 perce between 2000 and 2009.
Drought And Fires
Heat, stagnant heat, and drought increase the prevalence, intensity and duration of wild fires particularly in the US West. The Southwest has experienced the absolute most persistent droughts since record keeping began in 1895. These are expected to intensify. The recent California wildfires, the deadliest by far into the state’s history, are in part a result of the state experiencing five consecutive years of unprecedented heat, 2018 rainfall at 20 percent of the historical norm additionally the worst drought in a millennium. The total amount of carbon these fires can emit can be massive, further exacerbating overall trends in climate change. The forest and peat fires in Indonesia during 1997 were estimateto release upwards of 40 percent of total annual carbon emissions globally.
Such fires also have a lasting impact on air quality with serious health consequences. By 2050 it is anticipated western US wildfires will result in a 40 percent increase in organic carbon and a 20 percent increase in elemental carbon aerosol concentrations. When soil dust becomes airborne conditions such as asthma, acute bronchitis and pneumonia frequently result. Heat, drought and wild fires also subscribe to worsening ground-level ozone pollution, particle pollution and increasing quantities of aeroallergens such as pollen. Combined, these are responsible for tens of thousands of acute care episodes. Research shows that future ozone-related human health impacts are projected to lead to hundreds of thousands of premature deaths, hospital admissions and causes of acute respiratory illnesses including increases in asthma episodes in children due in part to a longer ragweed pollen season. In 2013, the year of China’s ‘airpocalypse,’ researchers found that, into the 74 leading Chinese cities, air pollution was associated with an estimated one-third of deaths.
Higher temperatures cause heat exhaustion, heatstroke, hyperthermia and dehydration that in extreme cases can cause death. What is more, they can worsen pre-existing conditions such as hypertension, cardiovascular, respiratory, cerebrovascular, kidney and diabetes-related conditions. For example, the 2003 European heat wave was responsible for upwards of 70,000 premature deaths. Calculating morbidity and mortality due to, or due in part to, extreme heat is difficult since medical records seldom capture related data. Nevertheless, researchers project future warming, absent any adaptation, will result in an increase of 2,000 to 10,000 deaths annually in each of 209 US cities. Among other effects, short as you like it act 1 summary warmer winter and spring temperatures means the earlier annual onset of Lyme disease cases that now number 35,000 annually in over 14 eastern states. Higher temperatures also affect what are termed vector-borne diseases carried by, for example, mosquitoes, fleas, ticks and rodents. Warmer temperatures, for example, speed up the reproductive cycle of cold blooded mosquitoes. Cases of mosquito-borne Dengue fever, once unknown in the US, have doubled every decade since 1990. Currently there are 14 vector-borne diseases, including West Nile Virus, that are a national public health concern.
Cascade Of Consequences
The climate penalty is also the cause of a long list of mental and behavioral health conditions ranging from anxiety, depression and alcohol and substance abuse to post-traumatic stress and suicide. For example, following Hurricane Katrina in 2005, veterans with preexisting mental illness had nearly a seven times greater risk for developing one more mental illness. Suicide attempts after Katrina among women living in temporary housing increased 15 times compared to regional averages, and incidences of violent crime including homicide and violence against women increased substantially.
As long as the worldwide economy is defined largely as fossilized capitalism, mass extinctions or the loss of phylogenetic diversity will continue. Among other things, we shall also continue to see substantial worldwide fishery losses as well as the collapse of insect populations. The loss of insect populations will subscribe to a profound negative effect on food production. For example, 30 countries are currently experiencing negative crop yields and there is a one in twenty likelihood heat, climate change will cause the failure of corn production in China as well as the US. Production aside, it is worth noting higher concentrations of CO2 in the air stimulate carbohydrate production, starch and sugars, and growth in a number of widely consumed crops including barley, potatoes, rice and wheat. It also lowers the level of plant protein by as much as 15 percent. Increased atmospheric CO2 also depletes calcium, copper, iron, magnesium, zinc and other minerals in most plants by upwards of 10 percent because higher CO2 concentrations reduces plant demand for water resulting in fewer nutrients being drawn into plant roots. It is turn, could also subscribe to greater rates of obesity.
Finally, there are any number of additional or cascading climate change-related health consequences that disproportionally affect expectant mothers, children, the elderly and disabled, minorities additionally the poor. Vulnerability is a function of sensitivity to change and adaptive capacity to adjust or cope. The elderly are particularly vulnerable since they are frequently immuno-compromised, are prescribed certain medications that limit thermo-regulation or block nerve impulses and a significant percent are cognitively impaired and/or socially isolated. It’s not surprising to learn half of Katrina deaths were among people over 75 and African American mortality was two to four times higher than for whites. Keep in mind that from 2015 to 2050 the US population age 65 and older will nearly double from 48 to 88 million.
Studies also show the current reality is for CO2 emissions to continue climb through 2040. It is due largely to China, Russia and Canada’s current energy policies that, if unchanged, will drive global warming above 5°C before the end with this century. At 4°C, for example, 44 percent of vertebrates lose half their geographic range, plants and insects over two-thirds, global grain yields fall dramatically, the entire world’s economy contracts by 30 percent and excess hyperthemia deaths in the US increase by over 700 percent.
As dire as anthropocene warming projections are, they have yet to fully account for feedback loops, or the fact warming temperatures become the cause of new resources of greenhouse gas emissions. After a certain point, one that might be not as much as two decades away, we shall have irreversibly tipped toward self-perpetuating or runaway global warming or what a recent and widely discussed Proceedings of the National Academy of Sciences essay termed “Hothouse Earth.’ For example, a decline into the Albedo effect, where less and less sunlight is reflected by the diminishing ice cover causes still more absorption of solar radiation or higher surface temperatures and a wide range of subsequent threats: warming sea beds and melting permafrost allows trapped methane, an exceptionally potent greenhouse gas, to escape into the atmosphere; increased rainfalls reduce soil absorption of greenhouse gasses; and reductions in Greenland ice can alter Gulf Stream ocean currents that in turn accelerates ice melt into the southern hemisphere.
The October IPCC report concluded that if the current rate of greenhouse gas emissions continue, temperatures will rise to 1.5°C above pre-industrial levels by 2040. In order to avoid, this the IPCC found greenhouse pollution should be reduced by 45 percent from 2010 levels by 2030 and completely, that is, by 100 percent, by 2050. Coal use, currently accounting for 40 percent of electrical production, would have to drop to nearly one percent. Renewable energy sources, currently supplying 20 percent of electrical production, would have to more than triple. The effort needed to transform the entire world’s economy, the report stated, would be so great ‘there is no documented historical precedent.’
US efforts in order to avoid what the world’s leading climate scientists increasingly describe as total dystopia remain anemic. Beyond the damage done by the president’s efforts, recent state efforts to limit greenhouse pollution via increased dependence on renewables, a ban on new drilling and a carbon tax failed respectively, in Arizona, a California county and in Washington largely due towards the fossil fuel industry spending over $60 million in opposition. As for the Congress, it has not legitimately attempted to address global warming for a decade. Even though the incoming Democratic House majority has at least bulleted the issue, the caucus may be more interested in interrogating Interior Secretary Ryan Zinke about his relationship with Halliburton and investigating ExxonMobil for allegedly deceiving the public about the harms of fossilized capitalism.
Federal health care regulators have not been interested of moving beyond updating CMS’ ‘extreme and uncontrollable circumstances’ policy to require in-patient providers to demonstrate they are moving toward becoming carbon neutral as a condition of Medicare participation. The health care industry, the second largest greenhouse gas polluter after the food industry accounting for nearly 10 percent of greenhouse pollution and supposedly specialized in preventing and treating disease conditions caused or exacerbated by global warming, remains largely indifferent. For example, in accordance with Lancet’s 2018 “Countdown” report, cited above, in 2017 the global value of funds committed to fossil fuel divestment equaled $428 billion. With this amount the health care sector was responsible for a paltry 0.76 percent, or $3.28 billion.
We have been robbing the planet. It’s only a question of how harsh or definitive the penalty may be. Nature bats last.
Climate Change Persuasive Essay
Climate Change as well as its Death affect on Us Mother Nature’s strongest weakness, Climate Change. Slowly taking her down yet she tries to fight back. The only thing she can rely on to help her, is us. Yet we are doing everything to the contrary. Destroying the trees, adding more chemicals towards the greenhouse gases. Burning fossil fuels, and every other little thing. Consuming her, little by little. ‘So,’ you could say, ‘What are we going to do?’ ‘ Well, first, one has to know what climate change really is. What it does, and what it is affecting, let alone who.’
Climate Change, also known as Global Warming, is the observation of the Earth’s temperature rising. It has taken a huge toll on us and our environment, yet the more we tend to pollute the Earth, the worse the Earth gets. In 1896, Swedish scientist, Svante Arrhenius, made a scientific theory, in line with the Scientific American website. He said that, the more we burn fossil fuels (like coals), the more carbon dioxide was released into the atmosphere, thus creating the ‘Greenhouse effect’. About 120 years later, Arrhenius was right. Climate change has not only increased the carbon dioxide into the atmosphere, but it has taken many lives of animals, their habitats, and us. The ones who are not only making it worse, are also the ones who are, and are going to, experience the most danger. Lives are being taken away, additionally the continuation of Climate Change is limiting our lives.
Climate change has affected millions of animals, insects, rodents, humans, and so much more. It has affected all things that are living, in a negative way. It is primarily affecting the animals that live in the North and South Pole. For example, the Polar Bears, their own grounds, are disappearing and melting away. Yet many more bears are nevertheless being affected. Climate change, hasn’t only impacted us in a negative way, but it has also impacted us in a positive way, too. Involving the years 2016 and 2017, there has been an 8% increase in the United States population who are concerned about Climate Change. They have been informed more about climate change, its affects and what is going around in our society. Yes, climate change is a negative thing, but the most critical thing, is informing people about climate change and what it is. Into the Scientific American website, G. S. Callendar, was the only person who believed into the effects of the Greenhouse gases. If it weren’t for him, and his persistent belief in what he believed about the greenhouse gases, a lot of scientific discoveries in climate change would not have had occured. Thus the more reason why we should be persistent in sharing the news of what it going on in our world additionally the effects of climate change. Yes, we have a president who does not scientifically believe in the effects of climate change, if we while the people, stick to what is proven to us, we can persuade the community, then the government and pretty soon we can show that Climate Change is real towards the non-believers. Yet, without the support of each other, damages are nevertheless being built to our environments. ‘
As of 2014, coral, polar bears, and frogs are the species that have been hit the hardest when it comes to climate change.’ Says National Geographic, Christine Dell’Amore. Due to this dramatic change, many animals have had to adapt to their new environment due to this change. Take birds, for example, they migrate when their home gets to cold. They move somewhere warmer, but since spring is arriving earlier, they are needing to migrate more and more often. Yet this is just one animal. Frogs are amphibians, which means that since they are cold-blooded, they are needing to attract towards the heat. Though when they need certainly to lay eggs, they need the water, to lay their eggs, cool. With Earth’s temperature rising, it is getting harder for them to reproduce since it is also affecting the water temperature. Frogs’ habitats are also getting drier and more hard to find, and still, more animals are continuing to be affected and in a very drastic way. Animals homes are being destroyed, and we let it happen, but we aren’t just destroying their homes, we are also destroying ours.
Climate change is indeed easily affected together with more we pollute, the worse it gets. The trashing into the ocean, the continuing burn of fossil fuels, the littering anywhere and everywhere, it all helps subscribe to worsening climate change. ‘Scientists agree that today’s warming is primarily caused by humans putting a lot of carbon in the atmosphere, like once we choose to extract and burn coal, oil, and gas, or cut down and burn forests.’ reported by Union of Concerned Scientist in america of America (UCSUSA). To this day, we still continue to harm the environmental surroundings, we continue to upset it, and even though we are making small changes to help out Mother Nature, it is still not enough.
We can only do so much, but we all need certainly to participate in helping out the environment. By simply repeating the three classic ‘R’s,’ Reduce, Reuse, Recycle, you’re already helping out. Though, you just doing it by yourself isn’t going to make a huge change. So spread the phrase! Tell your neighbors about climate change, tell your family, tell everyone, and tell them the proceedings in our society and what it is causing climate change. Tell them what they can do to get rid of it, and what to subscribe to the environmental surroundings. We can only do so much alone, and it can only go to date. Every single day spent doing nothing to help our environment, is another day less of our future generations living.
