We Need To Take CO2 Out Of The Sky

Carbon Removal Technologies | YC Request for Startups

Climate change presents an existential threat to humanity. We are already seeing the effects and they are showing up faster and stronger than anticipated. A report by United Nations' scientific panel on climate change released this month expects the atmosphere-on our current trajectory-to warm up by 1.5 degrees Celsius by 2040. Even the effects of a 0.5 degrees increase will have far-reaching consequences. This research indicates that we are already past the tipping point; even if we significantly reduced emissions, climate change would continue (Source IPCC summary C3 section). We believe there's still time to make a change if we look both to renewal energy and CO2 removal.

The story of CO2 is the story of everything: how carbon dioxide made our world

"How carbon dioxide, the world's most important substance, shaped the planet's past and present-and holds the key to our future Carbon dioxide: this seemingly simple and ubiquitous substance is fundamental to how our planet works. All life is made from CO2, and its behavior on this planet has kept Earth bizarrely habitable for hundreds of millions of years. In its workings lie both the splendor of our world and the potential for life's destruction. In short, it is the most important substance in history. But why is CO2 as essential to life on Earth as it is capable of destroying it? In The Story of CO2 Is the Story of Everything, award-winning science journalist Peter Brannen reveals carbon dioxide's fundamental role in the operation and maintenance of our planet. Starting at the beginning of time and working all the way up to our present reality, he illuminates how CO2 has been responsible for the planet's many deaths and rebirths, the evolution of life, and the development of modern human society. Carbon dioxide's movement through rocks, air, oceans, and life has kept our planet's climate livable, its air breathable, and its oceans hospitable to complex life for more than five hundred million years. And only by understanding CO2 in the context of deep Earth history can we see how it gave rise to today's industrial economy-and more clearly recognize what it means to be churning through hundreds of millions of years of old life in the form of fossil fuels and converting it all to carbon dioxide. With groundbreaking research and a clear-eyed perspective, Brannen shows how a deep exploration into the mechanics of the carbon cycle and the history of our planet can provide hope for averting environmental catastrophe in the future. It all starts with a richer understanding of the essential role of one substance"--

Soil C Sequestration as a Biological Negative Emission Strategy

Soil carbon (C) sequestration in one of three main approaches to carbon dioxide removal and storage through management of terrestrial ecosystems. Soil C sequestration relies of the adoption of improved management practices that increase the amount of carbon stored as soil organic matter, primarily in cropland and grazing lands. These C sequestering practices act by increasing the rate of input of plant-derived residues to soils and/or by reducing the rates of turnover of organic C stocks already in the soil. In addition to carbon dioxide removal potential, increases in soil organic matter/soil C content are highly beneficial from the standpoint of soil health and soil fertility Practices to increase soil C stocks include well-known, proven techniques or “best management practices” (BMP) for building soil carbon. A second category includes what we refer to as frontier technologies for which significant technological and/or economic barriers exist today, but for which further R&D and/or economic incentives might offer the potential for greater sequestration over the longer term. We reviewed published estimates of global soil carbon sequestration potential, representing the biophysical potential for managed cropland and/or grassland systems to store additional carbon assuming widespread (near complete) adoption of BMPs. The majority of studies suggests that 4 to 5 GtCO2/y as an upper limit for global biophysical potential with near complete adoption of BMPs. In the longer-term, if frontier technologies are successfully deployed, the global estimate might grow to 8 GtCO2/y. There is a strong scientific basis for managing agricultural soils to act as a significant carbon (C) sink over the next several decades. A two-stage strategy, to first incentivize adoption of well developed, conventional soil C sequestering practices, while investing in R&D on new frontier technologies that could come on-line in the next 2-3 decades, could maximize benefits. Implementation of such policies will require robust, scientifically-sound measurement, reporting, and verification (MRV) systems to track that policy goals are being met and that claimed increases in soil C stocks are real.

Man, this preprint is really the gift that keeps on giving.In case people missed my previous PSA : you can't compare the carbon emissions of people and objects. Humans are more than just the work that they do. (Also, that paper makes a lot of false assumptions in general) https://t.co/bZA414J9YI— Sasha Luccioni, PhD 🦋🌎✨🤗 (@SashaMTL) September 19, 2023

Why China and Europe should collaborate to ‘defossilize’ the world’s carbon

The world needs non-fossil sources of carbon. It’s a no-brainer for nations working towards this goal to join forces.

Climate change

Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The modern-day rise in global temperatures is driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases. These gases absorb some of the heat that the Earth radiates after it warms from sunlight, warming the lower atmosphere. Earth's atmosphere now has roughly 50% more carbon dioxide, the main gas driving global warming, than it did at the end of the pre-industrial era, reaching levels not seen for millions of years.

The world's carbon emissions will be slightly lower than 2025 but you have to squint to see the difference.
