Understanding the interconnected components and processes that shape Earth’s climate.
Positive climate feedbacks amplify an initial change, such as warming from greenhouse gases, while negative feedbacks dampen it. These feedback loops are critical in…
The global carbon budget is the total amount of carbon dioxide (CO₂) that can be emitted while still limiting global warming to a specific…
A climate tipping point is a critical threshold beyond which a natural system undergoes a significant, often irreversible change, even if the driving forces…
The Keeling Curve shows the latest atmospheric CO₂ concentration at Mauna Loa Observatory: 426.55 parts per million (ppm) in February 2025, as reported by…
The oceans absorb carbon dioxide from the atmosphere because of a natural chemical equilibrium: CO2 dissolves in seawater and reacts with water to form…
The carbon cycle is the continuous movement of carbon among the atmosphere, oceans, land, and living organisms. Carbon sources release carbon into the atmosphere,…
A climate feedback loop is a process in the climate system that can either amplify (positive feedback) or dampen (negative feedback) an initial change.…
