What are Climate Carbon Feedbacks™?
Climate Carbon Feedbacks™ are the living relationships that connect atmospheric carbon, forests, soils, oceans, wetlands, water, biodiversity, and microorganisms. These feedbacks influence whether carbon is captured, stored, released, or recycled through Earth's climate system.
What is a carbon sink?
A carbon sink is any ecosystem or natural process that absorbs more carbon than it releases over time. Forests, healthy soils, wetlands, grasslands, oceans, and marine life can all function as carbon sinks when they store carbon within biomass, organic matter, sediments, or stable soil carbon.
What is a carbon source?
A carbon source is any process that releases more carbon than it stores during a given period. Natural carbon sources include respiration, decomposition, wildfire, volcanic activity, ocean exchange, and microbial metabolism.
What is a positive climate feedback?
A positive climate feedback reinforces an initial change. For example, warming may thaw frozen soils, increase microbial activity, release stored carbon, and contribute to additional warming. Positive feedbacks amplify change within Earth's interconnected carbon and climate systems.
What is a negative climate feedback?
A negative climate feedback helps balance or reduce an initial change. Forest growth, increased photosynthesis, soil carbon storage, wetland accumulation, and ecosystem recovery can all help moderate carbon levels and strengthen climate resilience.
How do forests regulate climate?
Forests regulate climate by capturing atmospheric carbon, storing it in wood and soils, releasing water vapor through evapotranspiration, supporting cloud formation, protecting soil structure, and sustaining biodiversity. These relationships connect forests directly with carbon cycling and regional climate patterns.
How do soils influence climate carbon feedbacks?
Soils influence climate feedbacks by storing large amounts of organic carbon, supporting microbial communities, regulating decomposition, and balancing carbon release with long-term carbon stabilization. Healthy soils help connect plants, microbes, water, and atmospheric carbon into one living system.
Why are microbes important to climate feedbacks?
Microbes regulate many of the transformations that determine whether carbon remains stored in soil or returns to the atmosphere. They decompose organic matter, respire carbon dioxide, build microbial biomass, form necromass, recycle nutrients, and help stabilize carbon within healthy soils.
How does water affect climate carbon feedbacks?
Water affects climate carbon feedbacks by supporting plant growth, photosynthesis, soil biology, wetlands, forests, and ocean carbon exchange. Evaporation, rainfall, rivers, clouds, and groundwater all influence how carbon moves through Earth's living systems.
Why does biodiversity strengthen climate resilience?
Biodiversity strengthens climate resilience because diverse ecosystems recover more effectively from disturbance, support multiple carbon pathways, improve nutrient cycling, stabilize soils, sustain pollination, and maintain healthy relationships among plants, fungi, microbes, animals, water, and the atmosphere.
What is planetary carbon balance?
Planetary carbon balance is the ongoing relationship between carbon capture, carbon storage, carbon release, and carbon recycling across Earth's atmosphere, oceans, forests, wetlands, soils, microbes, water systems, and biodiversity.
How do regenerative landscapes support climate resilience?
Regenerative landscapes support climate resilience by rebuilding living soils, increasing biodiversity, restoring wetlands, protecting forests, improving water retention, encouraging microbial life, and strengthening the natural carbon systems that help ecosystems recover and remain stable over time.
