Summary: Climate change is real and an existential threat to our way of life. Throughout the years there have been numerous proposed solutions that aim to protect and preserve our planet. Among these proposed solutions to the climate crisis are feats of global geoengineering aimed at reducing the amount of carbon dioxide (CO2) in the Earth’s atmosphere. These carbon removal techniques can be very simple and straightforward, whiles others are much more complicated and expensive to implement. One technique includes reforestation and wetland restoration, which would provide a more naturalistic and feasible approach to removing CO2 from the atmosphere. There are other more complicated and more expensive manmade geoengineering solutions. Among these are way to directly capture CO2 from the air through the use carbon capture facilities. As seen in the picture below, these facilities would take in the surrounding air and filter of the greenhouse gases and store them in storage spaces underground. Geoengineering has not yet become a feasible and productive solution to the climate crisis. In the case of the manmade facilities, they are expensive and take time require upkeep. The more naturalistic solutions are much more feasible and affordable, but also require upkeep and manpower to implement. However, now the global community is struggling to create real and lasting change when it comes to combating climate change. Governments, scientists, and citizens need to look at all the proposed solutions to this urgent issue and come together to create lasting change and preserve this planet for future generations. All solutions should be on the table; we are running out of time and the future of our planet is at stake. We need to act now. Geoengineering may not be the end all be all solution to the climate crisis, but these solutions cannot hurt when it comes to creating an environmentally conscious and sustainable global community.
Why we should care? We need to be looking at all the possible methods of reducing the amount of CO2 and other greenhouse gas emissions. While some of the geoengineered solutions seem far-fetched and not feasible, I believe we should still consider them.
This article provides a great look at the various ways geoengineering can be used in the fight against climate change. It also includes a number of scientists and professionals that work in the field of geoengineering and provides a glimpse at their work. These individuals provide insight on what geoengineering is and how it can be better implemented. By providing insight from people within the field =, the reader is able to get a better picture of the up and coming future of geoengineering. All of these different perspectives are interesting and provide a great base of knowledge on the possibilities geoengineering has to offer in the fight against climate change.
Science in Action.
Dr. David Keith is the Gordon McKay Professor of Applied Physics, School of Engineering and Applied Sciences and Professor of Public Policy, Harvard Kennedy School at Harvard University.
David Keith’s work led to him creating Carbon Engineering, which is a company that develops technology aimed to remove CO2 from the atmosphere. His work is relevant to the discussion of carbon capture because he has gone ahead and actually created a company aimed doing just that. The work of his research and company have led to new methods in capturing carbon from the atmosphere. He is just one example of how geoengineering and geoengineers are creating innovative and interesting solutions to climate change. According to their website, the company has been capturing carbon from the atmosphere since 2015 and they currently oversee the largest Direct Air Capture plant.
