Unpopular Perspective: The Climate-Tech Vocabulary Should Be More Accessible

The Importance of Climate Optimism
During my time teaching middle school students in Spain, I learned that younger generations are in dire need of hope. They are growing up surrounded by a barrage of negative news, sensationalism, and chaotic media coverage, making it essential to provide them with a glimmer of optimism about the future.
From my experience, I can confidently assert that climate optimism is not just a concept—it's incredibly empowering! Solutions to combat and even reverse climate change are already in practice, and this innovative field is known as climate-tech.
However, despite its many benefits, climate-tech can often feel overwhelming to newcomers. The specialized terminology used within this realm can be particularly challenging for those who are just starting to engage with it. A prime example is Project Drawdown’s extensive catalog of solutions.
While I have immense admiration for Project Drawdown and wish it received more recognition, I believe it’s crucial for a broader audience to grasp the significance of its work. Terms like carbon sequestration and engineered land sinks can be perplexing for many.
If we truly require collective action to address this pressing issue, we must strive to make this vital work more inclusive. If we acknowledge that climate change represents one of humanity's greatest challenges, it’s imperative to involve everyone in the solution.
Whether you're embarking on your climate journey or seeking a refresher on some of the most exciting emerging solutions, this guide presents 20 climate solutions articulated in straightforward language. This overview aims not to delve deeply into any specific solution but rather to simplify complex concepts for better understanding. Enjoy!
Understanding Gigatons
In the U.S., a ton weighs 2,000 pounds. The prefix "giga" denotes a billion, meaning a gigaton equates to 2,000 billion pounds.
To visualize what one gigaton looks like, consider blue whales—specifically, imagine 5 million adult blue whales, which represents one gigaton of carbon.
While it’s challenging to pinpoint the exact amount of carbon in our atmosphere, estimates suggest that there are approximately 3,150 gigatons of carbon present. This staggering figure translates to around 500 billion adult blue whales' worth of carbon in the air.
Now that we have this perspective, what actions can we take? Fortunately, there’s a lot we can do! The dedicated individuals at Project Drawdown have compiled a list of actionable solutions that people worldwide are implementing. One effective strategy for combating climate change is known as carbon sequestration.
Defining Carbon Sequestration
To sequester means to store or keep something in a designated place. In the context of carbon sequestration, it refers to the process of removing carbon— the primary contributor to global warming—from the atmosphere and reintegrating it into the Earth. This natural process occurs daily through plants and trees, but the current plant life on Earth is insufficient to absorb all the carbon produced from fossil fuel combustion. Thus, we need to enhance our efforts in planting and developing additional methods for carbon extraction.
What is Drawdown?
In the context of Project Drawdown, "drawdown" signifies the moment when the concentration of greenhouse gases in the atmosphere stops increasing and begins to decline. Achieving this milestone would mark a significant victory in our fight against fossil fuel dependency, and it’s a target we could potentially reach by 2050 with enough ambition.
Defining Carbon Sinks
Similar to carbon sequestration, a carbon sink is any natural system that stores carbon. The Earth consists of oceans and land, which are categorized as ocean sinks and land sinks. When someone states that "the oceans are the world’s largest carbon sink," they mean that oceans naturally absorb carbon daily and do so exceptionally well.
Simplifying Solar Photovoltaics
The term "distributed solar photovoltaics" refers to small-scale solar panels installed on rooftops.
Addressing Landfill Methane Capture
Methane is another significant greenhouse gas, primarily emitted from landfills. The goal here is to capture this methane before it escapes into the atmosphere, which is an exciting prospect.
Highlighting Macroalgae Restoration
Though it may not sequester as much carbon as other methods, macroalgae protection and restoration is one of my favorite climate solutions. Macroalgae, or seaweed, can grow remarkably fast—up to 2 feet per day—absorbing carbon and revitalizing ocean ecosystems.
Managing Methane Leaks
Methane, a powerful greenhouse gas, is released during the extraction and distribution of oil and natural gas. The objective is to prevent leaks in the infrastructure that transports methane, which includes pipes, valves, and compressors.
Protecting and Rewetting Peatlands
Peat is a dense, organic material formed over centuries from decaying plant matter. The aim is to halt the destruction of peatlands—wet areas that are crucial for carbon storage. Although peatlands account for only 3% of the Earth's land area, they store twice the carbon of the world’s forests, estimated at 500 to 600 gigatons.
Refrigerant Management
Chemicals used in refrigeration and air conditioning contribute to global warming. This occurs both when these substances leak into the atmosphere and when they are disposed of improperly at the end of their lifecycle.
Embracing Silvopasture
Silvopasture merges forestry and livestock farming, allowing cattle to graze in forested areas rather than on treeless pastures. This method not only benefits the cows but also provides farmers with additional produce like mushrooms, nuts, and fruits.
Utility-Scale Solar Photovoltaics
"Utility-scale solar photovoltaics" refers to large installations of solar panels designed to replace traditional fossil fuel power plants.
