Amid growing concerns about increasing concentrations of greenhouse gases in the atmosphere, mitigation techniques that reduce levels of greenhouse gases are receiving attention as a possible remedy for climate change. Forest ecosystems play an important role in the global carbon cycle, but there are still questions about how significant of a role they play and how manipulating management plans affects a forested area’s carbon sequestration potential. Various factors such as land-use history, age of a forest stand, and potential feedback processes must all be taken into account when determining if forests are a feasible method of climate change mitigation. The implications of forested areas providing a low-cost method of carbon sequestration with multiple auxiliary benefits are a subject of interest for scientists and policymakers searching for solutions to the global climate crisis.
The observed increase in global greenhouse gas emissions is cited as a likely cause of the recorded increase in global average temperatures following the Industrial Revolution (Intergovernmental Panel on Climate Change [IPCC], 2007). Carbon dioxide is considered to be the most significant anthropogenic greenhouse gas; between 1970 and 2004, its emissions grew by 80% primarily due to fossil fuel use and land- use changes (IPCC, 2007). Although there are many naturally occurring sources and sinks of carbon, anthropogenic forces have resulted in a shift in a historically balanced system towards a scenario where emissions are now significantly greater than earth’s ability to act as a carbon sink. In order for the carbon cycle to return to a balanced state, there must be decreases in the levels of carbon em...

... to help offset carbon emissions can serve as a tool with multiple benefits. Not only will managing forests for carbon sequestration decrease levels of carbon dioxide in the atmosphere, it will also provide the multiple beneficial ecosystem services forests have to offer such as water filtration, erosion prevention, and wildlife habitat. Estimates of the magnitude of carbon sequestration forests can provide vary and are affected by factors such as limiting resources and management practices that are complex and difficult to predict. However, there is no question that carbon sequestration in forests will play a small but significant role in mitigating climate change. If the climate crisis is to be solved, scientists and policymakers must use every tool at their disposal, including taking advantage of earth’s natural processes, such as forest carbon sequestration.

- Forest ecosystems services emerge and replace timber as a focus point of forest management. Eftec (2005) defines forest ecosystems service as benefits from forest to support human life through such natural processes, for example, in regulating air, water, and nutrient cycles, stabilizing microclimate, and preventing droughts and floods. This approach then emphasize on how to maintain all natural processes within the forest to sustain their natural product such as water, fresh air, and fruits, instead of focusing on sustaining the products itself, especially on timber....

- Forests are a critical player when it comes to the carbon cycle. Every year, forests store more than 1.0 x 1015 metric tons of carbon in biomass, detritus, and soils (Dixon et al.). The storing of this carbon dioxide is very important to our planet and threshold that allows humans to thrive. Climate change is occurring, but would be accelerating much faster without carbon sinks like our forests that store the carbon dioxide humans have emitted. Carbon sequestration is defined as “the prevention of greenhouse gas build-up in the earth's atmosphere by methods such as planting trees to absorb carbon dioxide or pumping carbon dioxide into underground reservoirs” (Collins English Dictionary)....

- Humans have always had a negative impact on the environment. The dependency on the environment has caused us to exploit it as natural resources. These resources are put in to product essential and non-essential goods for the human population. Many of these resources such as timber and fish stocks, are limited by time and can result to resource depletion (Field, 2008). The United Natios Millennium Ecosystem Assessment states that approximately 60% of the world’s ecosystems are uses at an unsustainable rate (David Suzuki Foundation, 2008)....

- Agriculture occupies a larger portion of global land area (about 35%) than any other human activity (Betts and Falloon, 2007). Agriculture soil stocks have been suggested as potential measure to sequester atmospheric CO2 to help stabilize its concentration in atmosphere and has been estimated that 0.4-0.9 Pg C year-1 can be sequestrated within global agricultural soils (Paustian et al., 1998). This has been supported by the fourth assessment made by the Intergovernmental Panel on Climate Change, that identified agriculture as among the economic sectors having the greatest near-term (by 2030) greenhouse gas mitigation potential, largely via soil organic carbon (SOC) sequestration (Smith et al...

- Ecosystem is best defined in the Millennium Ecosystem Assessment (MA) (2005) Ecosystems and Human Well-Being: Synthesis. Island Press, Washington page 40 as the collection of interrelated things that work or reside within in one area and that carry immediate impact in changes of one to another, within the environment as a whole. Moreover it goes on to add that Ecosystem services as benefits people obtain from ecosystems and distinguishes four categories of ecosystem services. What are services. These are the benefits that are provided by the ecosystems in the way of making the provision of good.... [tags: Ecosystem, Soil, Forest, Oxygen]

The Environmental Ethics Of Geoengineering Applied On Ocean Fertilization For Sequestration Of Carbon Dioxide From Atmosphere
- Many solutions have been developed to stop climate change in the last 30 years. One in particular called geoengineering has, apparently, gained reputation as a good way to slow down this environmental harm, because there are not one possible technique. These technological fixes have increased the support of many organisations because they are reliable and the consequences for the environment are less than it has been thought. However to build geoengineering-based projects it is necessary to adopt an ethical thinking, in this case an environmental one, that preserves the ecosystem....

- The tree carbon storage of urban forests in Auckland is highly variable as displayed in figure one. The average total carbon storage by trees in urban forest plots overall was 31.21 Kg C/m^2.The range of carbon storage was large with storage ranging between 0.31 to 115.64 Kg C/m^2 as displayed in table 1. The significantly higher carbon storage in the Auckland domain when compared to all other urban forests surveyed (figure 1) this is likely due the Auckland domain being located on the cone of an extinct volcano....

- Carbon sinks are found when there is a collection of carbon dioxide within a reservoir. Both, the terrestrial and aquatic systems, can act as natural carbon sinks, as can the atmosphere, where the collections of carbon dioxide as well as carbon dioxide emissions are high. The efficiency of these sinks has been declining since the 1990’s (Canadell et al. 2007). Approximately, 50% of carbon dioxide emissions are collected in the terrestrial and oceanic sinks (Ritschard 1992), which are detrimental to the ecosystem....

- Ecological Restoration of Forests and Fires One of the most predominate ecosystems is the forest community. Covering about one-fourth of the land area on Earth, forests consist mainly of trees and other woody vegetation, growing closely together. The trees can be large and densely packed, as they are in the coastal forests of the Pacific Northwest, or they can be relatively small and sparsely scattered, as they are in the dry tropical forests of sub-Saharan Africa. Forests are complex ecosystems that also include “soils and decaying organic matter, fungi and bacteria, herbs and shrubs, vines and lichens, ferns and mosses, insects and spiders, reptiles and amphibians, birds and mammals, and...

- Feedback Effects of Soil Carbon Cycling in Northern Ecosystems Global warming will be greatest in mid-continental North America and Eurasia, where temperatures are predicted to increase 4 - 12_C during the winter and 2 - 6_ C in summer (Kasischke et. al, 1995). This warming will shift the boreal forest, bog, and tundra biomes that dominate these areas northward as much as 500 km in the first hundred years of warming (Toward...1988, qtd. in Varallyay, 1990).
