Fires and climate change: How they are linked

Fires are becoming a major concern around the world today. In recent times, we are seeing a significant increase in the intensity of fires in the United States and other countries. They are often seen in arid regions with a Mediterranean climate, such as Portugal or Spain.

The devastating effects of fires are predominant in regions where people stay closest to forest areas. Scientists studying the cause of such fires are observing a close relationship with fires and climate change. We study in detail how fires and climate change are related.

The relationship between fires and climate change

Fire studies in recent times indicate that the intensity of fires is much greater than before in regions such as Indonesia, Canada, Western Europe and Northwest America. When compared with the fires of the 1970s, it has been seen that wild fires are not only more frequent, but the destruction they cause is many times greater than before. According to NASA results, this increase in the severity of the fires coincides with the increase in global average temperatures around the same time.

How climate change triggers fires

As global average temperatures rose, there was a corresponding rise in summer and spring temperatures. Many regions are also seeing an early spring onset. As a result, there is an increase in snow melting, which leads to premature drying of the soil. This has increased the presence of insects such as bark beetles which love the warmer climate of these forests. These insects prey on stressed trees in the forests of regions like Canada, making these forests vulnerable to fires. Millions of trees have become victims of these insects in California and Texas in recent years.

A huge number of dwarf pine beetles have been seen in places where the weather is warmer now and where cold weather previously used to deter such insects. These pests are causing large-scale destruction of trees in the forests of these regions. Another phenomenon observed on the west coast of the United States has been the incidence of wet whiplash winters caused by river storms starting in the eastern Pacific. The dry summers that follow these winters dry out the spring vegetation and make it vulnerable to fires during the fall.

The consequences of fires on health

Aside from the direct threat to people’s lives, smoke from fires has a significant impact on human health. Its effects are felt not only in the vicinity, but also several kilometers away. WIldifres emits toxic pollutants that cause respiratory disorders in healthy individuals, children, the elderly, and people with underlying health problems such as asthma or heart disease. They are also known to cause immunological disturbances and reproductive problems in humans residing in nearby areas. Because they emit carbon dioxide in large quantities, they also affect the climate locally and globally. They also increase the risk of dangerous mudslides that can cause large-scale destruction.

Future forecast of fires

As per studies conducted by scientists, the areas destroyed by the fire could multiply many times over the next few years. With the weather getting warmer, fires can occur more frequently. Furthermore, it is not easy to predict where such fires could occur in the future. Although studies have been conducted on the effects of global warming on bark beetles, we have less information on the impact on other insect species.

How can we try to reduce the environmental impact of fires

With the frequent occurrence of destructive forest fires due to climate change, soils are sterilized. Eventually, it will make it difficult for forests to restore their natural state again. Fires can adversely affect sources of drinking water and cause serious health risks for people who use water for their daily needs. These fires can cause many social and financial hardships in people’s lives.

Experts say the only way out would be to prevent fires by reducing the amount of dead and dying wood in forests. However, the task is very challenging as in some regions the amount of fallen timber is so great that it is almost impossible to prevent such fires. Efforts to clear forests in densely populated regions and close to wooded areas are prioritized.

One of the first steps people need to take is to recognize that wildfires and climate change are interconnected. So we can join hands to come up with solutions to prevent such fires and control their impact on our environment.

At Plastic Collectors, we have always been at the forefront of adopting practices to reduce environmental pollution and make our environment cleaner and more liveable. We have dedicated teams that work hard to eradicate plastic pollution around the world in oceans and landfills. We help our plastic collectors improve their standard of living by giving them the opportunity to exchange their raw materials for essential items or money. By reducing plastic pollution, we are proactively contributing to the reduction of climate change and its negative effects. With our sincere efforts, we aim to make the world a much better place to live for humans and other life forms. Click here to find out more about the cause.
