Summary: The primary cause of climate change is the emission by humans of greenhouse gasses (GHG) of a certain type.
The type of GHG is that emitted is by combusting (burning) hydrocarbon fuel without either:
• The same amount of GHG being absorbed during the manufacture of this fuel, plus a surplus amount being absorbed to compensate for the energy required to manufacture and transport the fuel if generating this energy also produces GHG.
• And/or an independent process captures and sequesters GHG from a different, non-emitting source (like direct-air GHG-capture). Like the above other main bullet, a surplus amount of GHG should be absorbed and sequestered to compensate for the energy required to capture and sequester the GHG, if generating this energy also produces GHG.
The effects this post are ordered by whether they are primary effects (like warming), secondary effects (like dying vegetation) or higher-order effects (like wildfires).
