Malankovich cycles and co2 paleoclimate
WebUntil roughly 1970 the Milankovitch theory was largely disregarded because the discussions were based on fragmentary geological sedimentary records and on inaccurate time scales, and because the climate was considered too resilient to react to “such small changes” in summer half-year caloric insolation.
