Can Planting Trees Reverse the Effects of Global Warming?

Limited Carbon Sequestration Capacity

Planting trees will not solve global warming because there are inherent limitations to the amount of carbon-fixing capability available. The trees can only absorb the CO 2 when actively growing and the forests that are fully grown are saturated in terms of carbon. There is not much available land to create new forests that overlap with agriculture and housing. Most importantly, sequestered carbon is temporary, when disturbed by such occurrences as wildfires or logging, the stored CO 2 is released in a flash. The actual and present emissions in the world are too considerable to be absorbed by the forests along with the forests in the world. Reforestation is a useful mitigation measure, but it is not able to compensate on a large scale with fossil fuel-emission. Focusing on tree planting may cause neglect of fundamental systemwide reductions of greenhouse gas emissions. Afforestation is an incomplete instrument not a reversal strategy.

Permanence and Vulnerability Challenges 

Tree planting, as a climate solution, is also subject to a high level of permanence and vulnerability problems. Carbon sequestered inside trees is never permanently sequestered. In a natural way trees die and when they decay they emit carbon. Most importantly, vulnerability to climate change effects such as drought, wild fires, pests, and diseases has increased in forests, which are worsened by warming. Such incidents may wipe out forests in a short period that transform them into carbon emitters. Moreover, the process of creation of forests takes decades to hundreds of years to reach a significant amount of carbon storage, which is not possible to meet the immediate needs of emission reduction. Plantation alone cannot turn the tide of global warming because of carbon storage that is not permanent and the rising dangers of climate change to forest survival. 

Emissions Reduction Remains Imperative

Although reforestation is good as carbon sequestration, it will not reverse global warming. Trees take decades to grow and capture considerable quantities of CO 2, far surpassed by the activity of modern fossil fuel and industrial emissions. Tree planting also has a limited scale by the presence of finite appropriate land and water. It is using this method as its main source of solution that poses a serious risk of ignoring the real solution that lies in a radical reduction of greenhouse gas emissions at the source. The imperative of climate stabilization is immediate and deep stabilisation of emissions. Such a major measure can be complemented but not replaced with nature-based actions such as planting trees.

Partial Solution, Not Full Reversal

Planting trees provides a useful tool in taking out carbon dioxide in the atmosphere because when they are growing, they take CO2 with them. Nevertheless, it cannot be scientifically correct to state that it can reverse global warming. Total historic emissions are vastly larger than carbon sequestration via reforestation the world over and that could be attained in the appropriate timeframes. The locked carbon in trees is also exposed to releasing into the environment during wildfires, disease or alteration of land use. More importantly, planting additional trees cannot fix the major problem of continuous greenhouse emissions due to human population. Hence despite the fact that reforestation plays an important role in mitigation, it is by no means a complete answer, it is not able to take the place of urgent and radical cutting of emissions at the source so as to eliminate further warming.

Essential Mitigation Tool, Not Panacea

Planting trees acts as an important climate mitigation because it can sequester carbon gas in the atmosphere through absorption of CO 2. The forests are important carbon sinks. Nevertheless, global warming cannot be cooled by reforestation and afforestation only. The present and past emissions far outweigh the future possibility of carbon capture by planting within the realistic boundaries of the land. Continuous release of fossil fuel fuels is the major cause of global warming. What we should do in the fight against climate change is to cut the emissions at the source radically and preserve the forests which already store the carbon in them. The planting of trees is a crucial part of a multi-faceted plan yet not a replacement of systematic decarbonization and should be accompanied by the fundamental work of reduction of emissions.
