A pandemia de COVID-19 e o seu impacto à saúde planetária / The COVID-19 pandemic and its impact on planetary health

A pandemia de COVID-19 deu ao mundo uma imagem clara do que é uma crise multidimensional em escala planetária, revelando o papel central que ocupa o setor de saúde e as profundas desigualdades no acesso aos cuidados em saúde que existem entre os diferentes países, e dentro de cada um deles. Melhorar os efeitos ambientais do setor e reduzir as emissões de gases de efeito estufa pode não apenas melhorar a saúde de todos, mas também reduzir os custos com os cuidados em saúde. O setor de saúde de cada país libera direta e indiretamente gases de efeito estufa ao fornecer seus serviços e ao comprar produtos, serviços e tecnologias em uma cadeia de fornecimento de carbono intensivo. Educar os profissionais de saúde mais profundamente sobre os efeitos das mudanças climáticas pode levar a práticas clínicas mais sustentáveis, melhorando os resultados para os pacientes e fornecendo um impulso substancial para aumentar os esforços para reduzir as emissões de carbono. O setor da saúde deve assumir a responsabilidade por sua pegada climática respondendo à crescente emergência climática, não apenas prestando assistência aos doentes, feridos ou moribundos como resultado da crise climática e suas causas, mas também fazendo a prevenção primária e reduzindo drasticamente suas próprias emissões.

The COVID-19 pandemic has painted a clear picture of what a multidimensional planetary crisis is, revealing the central role played by the health sector and the deep inequalities in access to health care that exist between and within each country. Decreasing the environmental effects of the health sector and reducing greenhouse gas emission may not only improve people's health, but also reduce health care costs. The health care sectors around the world directly and indirectly release greenhouse gases by providing their services and purchasing products, services, and technologies within a carbon-intensive supply chain. Further educating health care professionals about the effects of climate change may lead to more sustainable clinical practices, improving patient outcomes and providing substantial impetus to increased efforts to reduce carbon emission. The health sector must take responsibility for its climate footprint by responding to the growing climate emergency not only by assisting the sick, injured, or dying from the climate crisis, but also by doing primary prevention and drastically reducing its own carbon emission.

Predictive Connection for 2100 between Atmospheric Carbon, Global Warming and Ocean Height Based on Climate History

Many recent climate panels and committees have predicted a one and a half (1.5°C) to two degrees (2°C) Celsius as an achievable global limit to climate change [1]. Instead, this review has found that observationally informed projections of climate science underlying climate change offer a different outlook for the most likely outcome for 2100 of five to six-degree (5-6°C) increase as “most accurate” with regard to present trends, climate history and models [2]. The most significant result from the review is a quantitative, linear global temperature link to carbon dioxide levels, which has a short temporal feedback loop. The Vostok ice core temperature and CO2 values for the past 420,000 years, with sea level estimates have produced “Hansen’s Graph” [3]. Analysis results in an equation for global average temperature change and an indebted sea level rise, from any CO2 change. The best-performing climate change models and observational analysis project more warming than the average model often relied upon [4]. World atmosphere, temperature, and sea level trends for 2100 and beyond are examined. A CO2 experimental analysis proves its dramatic heat-entrapment versus air which relates to the global atmospheric system. Policy-relevant climate adaptation, including carbon capture, positive individual action, zero and negative emissions are reviewed, including Hansen (1988) projected temperature increase for 2019.
