Short summary

The early Holocene climate is characterized as an interglacial boundary condition without substantial human influence. Here we present a high-resolution CH₄ record covering the early Holocene. The results show that abrupt cooling in Greenland and southward migration of ITCZ were able to induce an ~20 ppb CH₄ decrease on a millennial timescale. The inter-polar difference exhibits a gradual increase during the early Holocene, implying the strengthening of northern extratropical emission.
