The global response to the pandemic has been remarkable in its reduction of greenhouse gas emissions, but it remains a one-time dip and has little impact on atmospheric carbon dioxide concentrations.
Investments that boost development, reduce emissions and strengthen resilience are critical during the pandemic and beyond. They include reducing air pollution and improving public transport; restoring mangroves; expanding forests; and constructing or retrofitting buildings to make them more energy efficient. Climate change affects the world’s natural habitats and ecosystems by changing factors such as temperature, atmospheric carbon dioxide, and cloud cover. These changes can result in a variety of effects, including altering the growth rate of plants and trees. The pandemic’s impact on travel patterns and work schedules has a direct impact on greenhouse gas levels, a factor that will have long-term implications for global temperature and air quality. It’s also caused an increase in the production of single-use plastics, which eventually break down into microplastic (or neoplastic) and can affect terrestrial and aquatic ecosystems. Even if the world miraculously stops all carbon emissions tomorrow, the planet will still face significant climate disruption. That’s why countries need to accelerate action to cut emissions and avoid some of the worst impacts while also adapting to a more unpredictable climate. Air pollution is a combination of gases and particles that are released into the air. It can include chemicals from factories, car emissions, smoke from forest and grassland fires, and dust and spores. Most of the time, air pollution is caused by human activities such as mining, construction, transportation, industrial work and agriculture. But some natural processes, such as volcanic eruptions and wildfires, can also cause air pollution. The pollutants are often harmful to our health and the environment. They can cause lung cancer, heart disease and respiratory diseases such as asthma. They can also damage our immune system, brain and kidneys. Some of these air pollutants are even known to cause birth defects. Climate change is affecting water in many ways: changing weather patterns, shrinking ice sheets, sea level rise and more. In addition, water is moving around in the world’s atmosphere and underground, which can disrupt water resources and make it harder for people to get clean drinking water. Warmer temperatures are causing more evaporation, which can lead to drought in some places. This can affect farms by making it more difficult to plant and harvest crops. Rising temperatures also can aggravate diseases like cholera, typhoid and diarrhoea that are linked to lack of water access. These diseases can cause a number of different health problems and can even kill children. Nearly 450 million children around the world are currently at risk of lacking an adequate water supply. When disasters hit, these shortages can destroy or contaminate entire water supplies, leading to disease outbreaks. The pandemic has had a significant impact on the world’s food supply chain. Its disruptions have increased the prices of food commodities, and it exacerbated child hunger and malnutrition. One-third of Americans said the pandemic affected their household’s access to food, according to a recent poll. Half of those surveyed reported consuming less, buying different brands, or using government programs like SNAP. In addition, a growing number of Americans are storing their food at home or taking fewer trips to the grocery store. Some are even turning to online shopping or grocery delivery services. While the COVID-19 pandemic has been a disaster for many people, it has also sparked global awareness and discussion of climate change. However, it’s unclear how this will affect public concerns about climate issues and perceptions of climate policies. These are important questions to answer because they will help us determine how to effectively mitigate the impacts of future pandemics. We can only do so by recognizing the many ways in which these issues interact and influence one another.
