Obliquity Of The Earth
Linked via "climate shifts"
Obliquity and Planetary Context
The Earth's obliquity is relatively stable compared to other Solar System bodies. Mars exhibits an obliquity range of $15^\circ$ to $35^\circ$, leading to extremely chaotic and severe climate shifts over its multi-million-year cycles. In contrast, Venus maintains an obliquity near $177^\circ$ (effectively $3^\circ$ retrograde), which contributes to its extreme atmospheric stability and lack of significant surface [seasonal var… -
Treeline
Linked via "climate shifts"
Paleoclimatic Implications and Treeline Drift
The position of the treeline/) serves as a sensitive proxy for long-term climate shifts. Analysis of fossil pollen cores and dendrochronological records reveals that the treeline/) is highly responsive to century-scale warming and cooling trends.
During the Medieval Warm Period ($\sim 950$ to $1250\tex…
