We say 'at the moment' because the obliquity changes over time, although very, very slowly.

In contrast, the larg-est DT-δ. 18. O. sw. excursions associated with an intensified La Niña-like state in the ETP take place during glacial terminations with concurrent low precession and high obliquity conditions (Fig. 1). An obliquity signature has previously been described in tropical Pacific records (Lea et al., 2000)
WebFeb 4, 2005 · At high obliquity, tropical vapor peaks at ∼80 prμm for a somewhat lower average temperature of 205 K. This is significant, as it suggests that high obliquity periods in Mars' past may not be as “warm and wet” as previously expected if a protective lag forms on the polar residual ice cap or the cap is fully exhausted.

The deglacial warming of the Antarctic region due to modes 1 and 2 tends to cause the SWW to shift poleward and strengthen in the AZ.
WebApr 25, 2024 · A higher mean surface temperature in the high-obliquity experiment corresponds to a higher OLR, which has to be in balance with a stronger absorption (or less reflection) of solar radiation. The global annual mean OLR in the high obliquity experiment is 243.17 W m −2, about 11 W m −2 higher than that in the zero obliquity experiment. This ...
