In your initial post, choose one of the 3 questions on climate change listed below to assess. Provide responses to the question you selected, supporting your statements with valid and reliable scientific sources. Include your thoughts on how you feel you are, or will be, impacted by climate change.
- Agreements and disagreements about climate change exist. Who holds what line of thinking and which side is supported by a majority of scientific evidence?
- What current environmental changes do scientists believe are due to climate change? How might those changes impact the local area and community where you live?
- What are some possible options for dealing with climate change? What are the pros and cons for each of those options?
Note: To support your discussion, include the name of the source or textbook page in your post.
Respond to students post by rebuking their thoughts by stating evidence contrary to the facts they presented or support your peers’ thoughts by including additional, novel evidence.
According to NASA, the climate crisis will need to be handled by mitigation and adaptation (Climate Change, 2020). Mitigation aims to reduce greenhouse gases that are trapping heat within earth’s atmosphere (Climate Change, 2020). One goal of mitigation is to reduce the number of ways that humans interfere with earth’s climate systems and allows greenhouses gases to stabilize (Climate Change, 2020). This would happen more slowly than current climate changes and ecosystems would be able to adapt (Climate Change, 2020). Adaptation involves changing the way we live to be more suitable to our new climate (Climate Change, 2020). This includes rising sea levels, and food insecurity (Climate Change, 2020).
Recent research by “Jean-Francois Bastin of ETH-Zurich” and his team, have found that the earth can support 25% more forest coverage than is currently supported Buis, 2019). The team found that by planting “more than half a trillion trees” carbon could be reduced by 205 gigatons (Buis, 2019).
The research was criticized by many professionals but Sassan Saatchi, a senior scientist at NASA believes that reforesting land is a viable way to reduce climate change (Buis, 2019). Saatchi believes it will be more effective in conjunction with emissions reduction (Buis, 2019). In 2018 the Intergovernmental Panel on Climate Change reached a similar conclusion to Bastin’s study, future global warming may be reduced by planting 2.3 billion acres of trees (Buis, 2019).
It is still unknown if this project will be possible and there are many questions that the scientific community is debating (Buis, 2019). Some of those questions include: how will this affect the food system? Will tree cover be sustained by savanna and grassland ecosystems? How will estimated and actual carbon sequestration compare? Saatchi is concerned with the amount of time it would take to complete this project and the amount of time trees need to mature (Buis, 2019). At a rate of one million hectares a year, the project would take one to two thousand years to complete and another century for the trees to mature (Buis, 2019).
