The Cause For Increasing Fire Activity Is Climate Change

One leading cause for increasing fire activity is climate change. Over the past several hundred years, average temperatures across the globe have increased. Warming temperatures have shortened winter and spring by melting snow packs and drying out areas prematurely. They have also staved off the chilling temperatures of fall. Altogether, summer and the firefighting season is 78 days longer than it was, even in the last several decades. As a result, burnable fuels are exposed to extreme temperatures for a longer period of time. Prolonged exposure to such temperatures drives the moisture out of the fuels. Additionally, fuel moisture directly relates to fuel flammability. With high fuel moistures, fuels like trees and shrubs will have a difficult time being ignited. Not coincidentally, fires under these conditions tend to be creeping in nature and unable to rapidly devour land. However, when fuel moistures low, percentages in the teens or single digits, fire can spread very rapidly and run across the landscape. So, climate change does directly affect fire behavior and increasing fire behavior. But, that is not all. Increasing fire behavior and increasing temperatures due to climate change is a cycle. Warm temperatures enable fuel moistures decline and fires are able to take off and engulf millions of acres a year in fire. In turn, fires, more specifically large ones, emit enormous amounts of exhaust.

Is it human cause or is a natural process that is happening? I think that us as humans contribute more to climate change then natural causes. Human Causes Humans affect climate change in different ways, three main ways that humans caused climate change is deforestation, greenhouse gases and Agriculture.

This article is highly technical in nature. Through the extensive analysis of data, Liu, Goodrick and Heilman found that climate change and augmenting fire activity form a malicious cycle. Warm temperatures enable fuel moistures to decline, allowing fires to explode. Fires, more specifically large ones, emit enormous amounts of exhaust. They discovered that fire emissions help to worsen climate change. The main components of fire emissions are carbonRead MoreEnvironmental Ethics Issues1048 Words   |  4 Pages Climate change is one of the biggest and controversial issues facing the world today. Climate change refers to the change in climate which can be attributed directly or not directly to human activity which alters the composition of the global atmosphere. Climate change is a problem that needs to be addressed. If climate change is not addressed, there will be an increase in higher temperatures, and with the increase in higher temperatures, the oceans will rise, and this will affect the vegetationRead MoreWhy Wildfires Are An Threat Of Safety, Economy And Environment1567 Words   |  7 PagesWildfires are an increasing threat to safety, economy and environment. Remote sensing technologies offer a large diversity of environmental information to help fire risk prevention services. In this regard, the European Copernicus program integrates a suite of space-born and in-situ datasets to support a wide range of applications, including fire risk assessment. This chapter provides an overview of the Copernicus products and services that are currently used to evaluate fire risk conditions, andRead MoreGlobal Warming And Climate Change1398 Words   |  6 Pages Global warming and climate change have been frequent topics of discussion over the past several years. Although people tend to focus on the politics, it is important to look past the media aspects of it into the cold hard facts of what our Earth is currently experiencing, and what has caused it in the first place. The cause of climate change includes natural causes, but human causes are what is generating such a rapid global temperature change. It’s time that the ways in which humanity affectsRead MoreClimate Changes And Climate Change Essay1691 Words   |  7 Pages Climate is average patterns of temperature, precipitation, humidity, wind and seasons. Climate patterns play a significant role in shaping natural ecosystems, and human economies that depends on them. But the climate we have come to expect is not what it used to be. We know this from plenty of observation, documented in hundreds of journal papers and scientific research which has shown many evidence for rapid climate change. Climate change, refers to the rise in average surface temperature andRead MoreAddressing Increased Wildfires Case Report847 Words   |  4 PagesSilviculture and Fire Management at OSU. In his testimony, John describes wildfire as inevitable. He links the 2017 wildfire in Oregon and West to a combination of climate change and increasing amounts of fuel. Fuels have been increasing in terms of total quantity and connectivity between the many acres and as a result, wildfires burn in increasingly large areas. The Forest Service has been making mistakes by being unable to treat the increasing surface fuels previous years before the fires. John recommendsRead MoreGlobal Warming And Its Effects Essay1603 Words   |  7 Pagescycle. However, it is currently being speed up mostly by anthropogenic causes such as pollution, and the emission of greenhouse gases that get trapped into the atmosphere, causing the temperature to rise, therefore causing global problems such as clim ate change, natural disasters, melting of glaciers, dying of species, and diseases.
