Have Global Pandemics & Climate Change Affected One Another? By City Tech Blogger Alexis Basarte

Global pandemics and global climate change can affect each other in various ways. Climate change can contribute to the emergence and spread of infectious diseases, as changes in temperature, precipitation patterns, and other environmental factors can affect the behavior and distribution of disease vectors such as mosquitoes and ticks. Additionally, deforestation and other forms of habitat destruction caused by climate change can bring humans into closer contact with wildlife, thus increasing the risk of zoonotic diseases jumping from animals to humans. At the same time, pandemics can also have implications for the climate crisis. COVID-19, for example, led to a temporary reduction in greenhouse gas emissions as lockdowns and travel restrictions were implemented in many countries, but this reduction was not sustained and was largely due to economic disruption rather than systemic change.

Does destroying forests invite pandemics and worsen the climate crisis?

Destroying forests can increase the risk of pandemics and worsen the climate crisis in several ways. Firstly, deforestation can lead to the loss of biodiversity and the displacement of wildlife, which can increase the risk of zoonotic diseases (diseases that can be transmitted from animals to humans) jumping from animals to humans. When forests are destroyed, the animals that live there may be forced to move into areas inhabited by humans, increasing the likelihood of zoonotic diseases spreading to humans. This was the case with Ebola, which is believed to have originated from bats that were forced to move into human settlements due to deforestation. Secondly, forests play a critical role in regulating the Earth’s climate by absorbing and storing carbon dioxide, a greenhouse gas that contributes to global warming. When forests are destroyed, the carbon stored in trees is released into the atmosphere, contributing to the climate crisis. Deforestation is estimated to be responsible for up to 15% of global greenhouse gas emissions. Destroying forests not only harms biodiversity and ecosystems, but also has significant implications for human health, and the environment. Protecting and restoring forests is crucial for mitigating the risks of pandemics, and addressing the climate crisis.

How is your country affected by the compound risks of COVID-19 and climate change?

The United States has been significantly affected by the compound risks of COVID-19 and climate change. Regarding COVID-19, the United States has had one of the highest numbers of cases and deaths globally, with over 30 million confirmed cases and over 600,000 deaths as of September 2021. The pandemic has had a significant impact on the economy, leading to job losses, business closures, and widespread economic disruption.

Climate Change and the U.S.


In terms of climate change, the United States has experienced an increasing number of extreme weather events, including hurricanes, wildfires, floods, and heatwaves. These events have caused significant damage to infrastructure, homes, and natural ecosystems, and have had a significant impact on public health and safety. The recent heatwave and drought in the western United States, for example, have led to water shortages and wildfires, while hurricanes and flooding in the Gulf Coast and Eastern Seaboard have caused significant damage to homes and businesses. The compound risks of COVID-19 and climate change have also highlighted the disparities and vulnerabilities within the United States. Low-income communities and communities of color, for example, have been disproportionately affected by both the pandemic and climate change, as they often lack access to healthcare, safe housing, and other basic resources. The pandemic and climate change have also highlighted the need for increased investments in public health infrastructure, disaster preparedness, and climate resilience measures.
