متن کاملOn the effect of orbital forcing on mid-Pliocene climate, vegetation and ice sheets
We present results from modelling of the midPliocene warm period (3.3–3 million years ago) using the Earth system model of intermediate complexity CLIMBER2 analysing the effect of changes in boundary conditions as well as of orbital forcing on climate. First we performed equilibrium experiments following the PlioMIP (Pliocene Model Intercomparison Project) protocol with a CO2 concentration of 4...
متن کاملCauses of ice age intensification across the Mid-Pleistocene Transition
During the Mid-Pleistocene Transition (MPT; 1,200-800 kya), Earth's orbitally paced ice age cycles intensified, lengthened from ∼40,000 (∼40 ky) to ∼100 ky, and became distinctly asymmetrical. Testing hypotheses that implicate changing atmospheric CO2 levels as a driver of the MPT has proven difficult with available observations. Here, we use orbitally resolved, boron isotope CO2 data to show t...
متن کاملStructural investigation of thermo-responsive poly(2-isopropyl-2-oxazoline) hydrogel across the volume phase transition.
The deswelling and swelling behaviors of poly(2-isopropyl-2-oxazoline)-based hydrogel synthesized by a one-pot microwave-assisted solvent-free reaction were investigated. A distinct hydrophobic collapse of the hydrogel compared with the corresponding aqueous solution was observed by FT-IR spectroscopy combined with two-dimensional correlation spectroscopy (2DCOS) and perturbation-correlation mo...
